What is a Science Investigatory Project?

Imagine stepping into the shoes of a scientist – asking questions, running experiments, and discovering the secrets of the world around you. That’s exactly what a Science Investigatory Project, or SIP, is all about.

At its core, a SIP is a thrilling journey of scientific exploration. It’s a project that challenges you to pick a problem, make educated guesses (that’s your hypothesis), roll up your sleeves for experiments, collect data, and connect the dots to find answers.

Here’s how it works

Step 1: the mystery.

You start with a question – something that piques your curiosity. It could be anything from “Why do plants grow towards the light?” to “What makes the sky blue?” Your SIP is your ticket to unravel these mysteries.

Step 2: The Guess

Next comes your hypothesis – a fancy word for your best guess at the answer. It’s like saying, “I think this is what’s happening, and here’s why.”

Step 3: The Detective Work

Now, it’s time for the fun part – experimenting! You set up tests, tweak variables, and observe closely. Whether you’re mixing chemicals, observing insects, or measuring temperature, you’re the scientist in charge.

Step 4: Clues and Evidence

As you experiment, you collect clues in the form of data – numbers, measurements, observations. It’s like gathering puzzle pieces.

Step 5: The “Aha!” Moment

When you analyze your data, patterns start to emerge. You connect those puzzle pieces until you have a clear picture. Does your data support your guess (hypothesis), or do you need to rethink things?

Step 6: Sharing Your Discovery

Scientists don’t keep their findings to themselves. They share them with the world. Your SIP report or presentation is your chance to do just that. You explain what you did, what you found, and why it matters.

So, why do SIPs matter? They’re not just school projects. They’re your chance to think like a scientist, ask questions like a detective, and discover like an explorer. They’re where you become the expert, the innovator, the problem-solver.

From the mysteries of biology to the wonders of chemistry and the enigmas of physics, SIPs open doors to countless adventures in science. So, what question will you ask? What mystery will you solve? Your SIP journey awaits – embrace it, and you might just uncover something amazing.

How To : The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.

What's an Investigatory Project Exactly?

An investigatory project is basically any science experiment where you start with an issue or problem and conduct research or an investigation to decide what you think the outcome will be. After you've created your hypothesis or proposal, you can conduct a controlled experiment using the scientific method to arrive at a conclusion.

What's the Scientific Method?

For those of us who have forgotten the various steps of the scientific method, let me clear that up right here:

Remember, however, that a successful investigatory science project does not necessarily have to result in the intended outcome. The purpose of these projects is to think critically, and if the solution doesn't work out, that doesn't mean your project will fail.

What Kind of Investigatory Projects Are There?

In order to conduct a great investigatory experiment, you have to ask an interesting question and be able to conduct an experiment that can hopefully answer that question. The harder and more intriguing the initial question is, the better the resulting investigation and experiment will be.

I've listed a few examples below of some of the best investigatory experiments out there, so hopefully you'll have no problem coming up with an idea.

Project #1: Making Soap Out of Guava

Basic hygiene should be available to everyone, but what about people who live in areas without easy access to grocery stores or pharmacies? This is a great question that makes you think about scientific alternatives to store-bought soap.

Below is an example project that creates soap from guava leaf extract and sodium hydroxide, but there's no shortage of materials you can use to replace the guava, like coconut oil or a fat like lard, butter or even the grease from your kitchen .

Project #2: Used Cooking Oil as a Substitute for Diesel

We all know how lucrative the oil business is, but what if the next huge innovation in oil was sitting right inside your kitchen cabinet? With the high prices of regular gasoline and diesel fuel, the possibility of creating a usable diesel fuel from household cooking oils is pretty exciting.

Although creating diesel fuel out of cooking oils that will run a BMW may sound like a reach, it still makes for a great project. And who knows, maybe in doing this you'll actually figure out what was missing from previous attempts . Being an instant billionaire doesn't sound too bad to me.

If you're interested in trying it for yourself, there's a great step-by-step guide with a full ingredients list and photos over on Make .

Project #3: Create Another Alternative Fuel

If biodiesel isn't your forte, you can try making oxyhydrogen gas or creating hydrogen gas via electrolysis or vice versa, creating electricity from hydrogen gas .

Project #4: Purifying Used Cooking Oil

Speaking of oil, if you use it to cook, you know that a lot of it goes to waste. But what if you could clean that oil and use it over and over again? Not only would that save money, but it would also benefit the environment since most people do not properly dispose of used cooking oil (no, pouring it down the drain doesn't count).

Your project goal would be to research methods of filtration or purification and test it on cooking oils. To easily demonstrate which method works best, try cooking some food in the oil produced by each one. Good food can go a long way when it comes to winning people over.

Check out the abstract and description of a similar project here .

Project #5: Alternative Methods of Producing Iodized Salt

In areas isolated from the sea, IDD or Iodine Deficiency Disease, is very common. Since these areas do not have easy access to marine foods or grocery stores, the population becomes very susceptible to the disease due to a lack of iodine in the diet. In order to combat this, researchers and doctors have begun infusing iodine into regular table salts.

If not iodine is readily available, it can be chemically made either with sulfuric acid and alkali metal iodide or hydrochloric acid and hydroxide peroxide .

But perhaps there are other more accessible ways to create an iodized salt that people could make at home. For a starting point, take a look at this previous experiment .

Project #6: Making Biodegradable Plastic

Plastic bags are actually illegal in Santa Monica , CA (and soon to be Los Angeles ) because of their threat to the environment due to insane resistance to biodegradation. I didn't think they were that bad, but one plastic bag can take up to 1,000 years to break down completely, and it can even ruin your car along the way. So, creating a better biodegradable plastic bag would be a huge achievement.

The only question is how one would go about doing so, and what materials could be used? That's the question you can answer for your project. This project used cassava starch as an effective component for a biodegradable plastic, but you could try using a few different starches and see what works best.

Project #7: Solar Water Purification

One of the biggest world problems is finding clean water. While we in the states can find purified or drinkable tap water almost anywhere, millions of people around the world don't have access to clean drinking water.

A few students decided to investigate a potential purification process using the sun's energy and an aluminum sheet. Watch the video below for more information and a complete walkthrough of their scientific process.

And if you're an overachiever, you can step it up a notch and try purifying pee instead .

Project #8: Perfecting the Paper Bridge

Of course, an investigatory project doesn't always have to answer such grand questions. This experiment looks to discover how to build the strongest paper bridge by varying how the pieces are held together. So, the question is, "How do design changes affect a load bearing structure?"

Check out the video below for more information on replicating the project yourself.

Project #9: Making Instant Ice

It's summer time and the degrees are already hitting triple digits in some areas. When it's this hot, there are few things better than a glass of ice chilled water or lemonade. But what happens if you don't have ice? Can you create your own ice or cool drinks quickly by another method? Check out this clip from King of Random .

Cool, huh? But how does it work? Is there any other way to replicate this? Well, let the investigation begin. Figure out what your hypotheses will be and follow along with this video for you own investigatory project.

For more information and additional photos, be sure to check out the King of Random's full tutorial .

Project #10: Increase the Shelf-Life of Fruits and Veggies

Extending the shelf-life of perishable fruits and vegetables can make a huge difference for small farmers, street-side vendors and even your average Joe—groceries aren't cheap. What is an inexpensive and easily accessible way to make produce stay fresh longer?

That's the question behind this great investigatory science project featured here . While these researchers focused exclusively on chitosan coating on bananas, you can branch out (no pun intended) and try an assortment of other fruits, veggies and possible coating materials.

For more information on how to keep your fruits and vegetables fresh for longer, check out my previous article , or Yumi's recent illustration for other ideas.

Project #11: Slow the Ripening of Sliced or Chopped Produce

You could also focus your project on keeping fruits and vegetables from browning after they've already been cut up. There are various methods and materials you can use to slow down the ripening process, such as honey and lemon juice. Watch the video below and read this tutorial for more information and ideas.

Your project could revolve around finding the best option, and testing out some of your own browning-prevention solutions to see if you can come up with a better one.

Project #12: Improve Memory by Thinking Dirty

If my memory was any good I would be fluent in Spanish and never need to look up the Quadratic Formula again. But my problems are more superficial, like forgetting where I put my keys or what time my dentist appointment was supposed to be. There are folks out there who do suffer from real memory problems, so figuring out how to help improve memory makes for a great investigatory project.

There are tons of studies on memory and memory loss that you can research. But for your investigatory science project, you will want to come up with your own hypothesis based on that information and test it out. Does using colors to form associations help with memory? Does linking an image with a memory increase its hold in the carrier's head? What about drinking grape juice or sniffing rosemary ? These are the types of questions you may look to answer.

This article contends that memory can be improved by looking at NSFW images or thinking of dirty associations. Come up with your own theory and let the brain hacking begin.

Project #13: Improving Social Anxiety by Manipulating the Body & Mind

Science experiments don't always have to include chemicals or test tubes. The science of the mind can be just as interesting. So what's the investigation consist of?

Can you truly affect the way you act and feel by simply changing your posture? Does acting a certain way manipulate the mind drastically enough to actually change the way you feel?

Check out Amy Cuddy's awesome TED Talk for more ideas for additional questions you could ask.

Project #14: Kitchen DNA Extraction

You may think studying DNA is only for professionals with super expensive lab equipment, but you can actually extract DNA from any living thing with a few basic ingredients you probably have in your kitchen like dish soap and rubbing alcohol.

Decide on something to vary, like different fruits and vegetables or types of dish soap, and come up with a hypothesis regarding which will allow you to collect the most DNA material.

You can also find more information, as well as another way to perform the experiment, here .

Project #15: Make Homemade Glue from Milk

With milk, white vinegar and baking soda, you can make your own glue right at home. Make it an investigatory project by changing up the recipe and testing which results in the strongest glue. You could also try varying the ingredients to make it dry faster, or work on different materials (wood vs. plastic vs. paper).

Project #16: Make a Battery Out of Fruits and Vegetables

How can you power a small light or device without electricity? You can make a DIY battery with a few different types of fruits and vegetables. Anything from a lemon to an apple , potato , or even passion fruit will work.

Pick a few different fruits or vegetables and form a hypothesis as to which will make the battery that puts out the most energy or lasts the longest. Once you've built your batteries, hook up a volt meter to read the output and see which one is the best.

What's Your Favorite?

100 Interesting Research Paper Topics for High Schoolers

What’s covered:, how to pick the right research topic, elements of a strong research paper.

• Interesting Research Paper Topics

Composing a research paper can be a daunting task for first-time writers. In addition to making sure you’re using concise language and your thoughts are organized clearly, you need to find a topic that draws the reader in.

CollegeVine is here to help you brainstorm creative topics! Below are 100 interesting research paper topics that will help you engage with your project and keep you motivated until you’ve typed the final period. 

A research paper is similar to an academic essay but more lengthy and requires more research. This added length and depth is bittersweet: although a research paper is more work, you can create a more nuanced argument, and learn more about your topic. Research papers are a demonstration of your research ability and your ability to formulate a convincing argument. How well you’re able to engage with the sources and make original contributions will determine the strength of your paper. 

You can’t have a good research paper without a good research paper topic. “Good” is subjective, and different students will find different topics interesting. What’s important is that you find a topic that makes you want to find out more and make a convincing argument. Maybe you’ll be so interested that you’ll want to take it further and investigate some detail in even greater depth!

For example, last year over 4000 students applied for 500 spots in the Lumiere Research Scholar Program , a rigorous research program founded by Harvard researchers. The program pairs high-school students with Ph.D. mentors to work 1-on-1 on an independent research project . The program actually does not require you to have a research topic in mind when you apply, but pro tip: the more specific you can be the more likely you are to get in!

Introduction

The introduction to a research paper serves two critical functions: it conveys the topic of the paper and illustrates how you will address it. A strong introduction will also pique the interest of the reader and make them excited to read more. Selecting a research paper topic that is meaningful, interesting, and fascinates you is an excellent first step toward creating an engaging paper that people will want to read.

Thesis Statement

A thesis statement is technically part of the introduction—generally the last sentence of it—but is so important that it merits a section of its own. The thesis statement is a declarative sentence that tells the reader what the paper is about. A strong thesis statement serves three purposes: present the topic of the paper, deliver a clear opinion on the topic, and summarize the points the paper will cover.

An example of a good thesis statement of diversity in the workforce is:

Diversity in the workplace is not just a moral imperative but also a strategic advantage for businesses, as it fosters innovation, enhances creativity, improves decision-making, and enables companies to better understand and connect with a diverse customer base.

The body is the largest section of a research paper. It’s here where you support your thesis, present your facts and research, and persuade the reader.

Each paragraph in the body of a research paper should have its own idea. The idea is presented, generally in the first sentence of the paragraph, by a topic sentence. The topic sentence acts similarly to the thesis statement, only on a smaller scale, and every sentence in the paragraph with it supports the idea it conveys.

An example of a topic sentence on how diversity in the workplace fosters innovation is:

Diversity in the workplace fosters innovation by bringing together individuals with different backgrounds, perspectives, and experiences, which stimulates creativity, encourages new ideas, and leads to the development of innovative solutions to complex problems.

The body of an engaging research paper flows smoothly from one idea to the next. Create an outline before writing and order your ideas so that each idea logically leads to another.

The conclusion of a research paper should summarize your thesis and reinforce your argument. It’s common to restate the thesis in the conclusion of a research paper.

For example, a conclusion for a paper about diversity in the workforce is:

In conclusion, diversity in the workplace is vital to success in the modern business world. By embracing diversity, companies can tap into the full potential of their workforce, promote creativity and innovation, and better connect with a diverse customer base, ultimately leading to greater success and a more prosperous future for all.

Ultimate List of College Science Fair Projects

• March 8, 2022
• Science Fair Ideas

College science fairs have been a trend in many universities across the world as science students get to showcase their projects.

Students are expected to make innovative designs on at least one of their projects while having a topic related to their subject to be discussed in detail during the fair.

For college students, these fairs are an excellent opportunity to showcase their learning while organizing the required resources. We will guide you through the science project ideas that you can make use of during your college science fair.

Whatever you choose, make sure that your project is well-researched and that you have spent enough time pondering the questions that you want to answer. With a bit of hard work and a little luck, you can achieve some amazing results at your college science fair!

College Science Fair Projects

College-level science fair projects in Physics

1. How do you apply a force to another object at the home of gravity, and then how does it react? Use any type( compass ) to determine which way an object would point after it was dropped from your height above the ground.

2. Experiment with speed dilation on our planet’s oceans. Explain why there is less light happening in front than behind/around them (Include sound).

3. Experiment with the solar wind. Explain what it is, determine the speed and strength of your planet’s magnetic field (Use magnetometer as necessary), its direction at noon/noon time in your place (+10 days) using maps, etc; compare this data to where you live on earth.

4. Measuring temperature differences between hot liquids that are next to a warm object such as a table or hand and more than one hot liquid next to a cooler object such as the base of an instrument; be creative and determine what temperature is most comfortable.

5. Using your knowledge of buoyancy, explain how you can influence your underwater exploration by adding weights (diving cowboy).

Environmental science fair projects for college students

1. Using nature for power generation – You can use multiple sources such as water, wind, natural energy, etc.

2. Experiment to produce energy efficiently.

3. Recycling water waste into electricity (in residences, classrooms or offices)

4. Printer conserving materials – combine recycled objects with more durable material for use in the production of 3-dimensional printing.

Psychology science fair projects for college students

1. Dissecting and identifying kinship, mating goals or a friendly relationship in an identification chart2. Doing statistics on which scent attracts the most flies when others sit down – behavioural biology is fast becoming integral to psychology; distinguish between empathy and sympathy (which are emotions); research effects of drugs like cocaine, caffeine etc increase blood flow, especially the prefrontal cortex (thinking part) necessary for critical thinking – link up with findings on behaviour.

3. The Stroop Effect – How thinking is affected by biased mental tasks.

Biochemistry science fair projects for college

1. The five stages of protein degradation for experiments against E.coli

2. Testing the DNA in a stool sample (see “Scoop” below) to determine how long ago an infection occurred − 1st stage bacteria die, 2nd and 3rd inhibits their growth − can help isolate which type of bacteria cause diseases.

3. Test cellular behaviour involving cancer by observing the formation of cancer cells in certain organs continuously for 15 minutes thus obtaining a fluorescent stain that is produced after several days. The result will determine if there are any abnormalities with cell growth.

4. Assessing vitamin/mineral deficiency caused by food toxins as well as direct effects from foods. Vitamin A, C, E and K all decrease when given high doses but can be replenished again so serum levels must be monitored to test the effect.

5. Lab experiment of what foods will affect blood pressure (elevation), glucose, cholesterol and lipids in each dish as well as which should be watched because they can decrease harmful substances while also increasing the amounts needed for homeostasis

6. Test if antibiotics are causing oxidative stress by testing if effects occur under conditions where salt intake is very high.

7. Test if it is possible to measure uric acid levels using urine samples, do not want any technicians touching your sample during the storage/ analysis process and keeping results secret on the computer that backs up results of the experiment!

8. Detect viruses using an instrument that is able to bidirectionally transmit the virus but filters out all other non-viruses. Also, it needs to be able to show traps and blanks in the coverage method

9. Lab experiment where one food sample has 2 different species created as food and tested for one species over weeks to see what happens.

10. Lab experiment where you grow bacteria/ yeast on a glass slide using the same media used by other biology labs.

2. Making a ‘Virtual Star’ i.e card with velcro attached to the back that when held up in front of a light source on earth you can see it from far away and therefore you know where it is by its movement

3. Using a camera and website to show the ball of light created by the sun on earth during different times

4. Telescopes and telescopes’ parts can be used in 3 ways: 1) Antenna, 2) filters to let only specific wavelengths through depending upon wavelength etc. or for example making telescope lens blanks (which are very fragile let people use this as a science project because they will learn how frustrating it is when they cannot get the lens ‘right’ using their science project)

5. Designing and constructing a telescope with different lenses designs for example, making them bigger or smaller

6. Ways to find something you want – 1) magnifying glass – look where you think it is (possible sites in the universe), 2) some other kind of device that determines altitude by contact with ammonia otherwise known as Becquerel’s Blue Ray or through looking at stars and based upon quantities recorded on the ground which are used by early humans to predict where the sun and stars could be.

9. Consider how a forensic exam would change over time and allow an officer to determine when the below might be static in cars and trucks (tires, brakes, ghia , etc)    Identify shapes of compound at different times without touching it!

Science experiments can help students learn and retain information in a number of ways. For one, they provide a hands-on way to explore scientific concepts. Experiments can also make learning more fun and engaging, which can lead to better retention rates. Finally, doing science experiments helps students develop problem-solving skills and critical thinking abilities.

In case you’re running out of time, try essay help for your science project. That might help you save time.

Here are some key tips to winning a college science fair

1. Be creative! Don’t select something too difficult as this will take more time, and possibly even fewer observations with better quality repetitive results that will give you clues to others’ thoughts on measurement error etc.

2. If you are uncertain of your ability to successfully conduct a project, select an easier one first – perhaps something simpler and conceptually sound that involves collecting data every now and then – like in our class above for insect tracking or take this 15-question quiz on starting a research project with many questions focusing on the feasibility.

2. Consider your data! Choose to collect certain information in every collection, and then remember prior thoughts you had as it pertained to that particular item/event.

3. Organize your project in such a way that will help you keep track of your results Not only the date, time and names for each type of observation (e.g., take pictures in digital format) put them into categories such as ‘date’ or just simply write it down on a piece paper at first to help remember specifics – especially if something happens more than once.

The first thing students should know is that research can be easy or hard depending on how they approach things. You see non-scientists like us somehow get confused by what “the rules” of doing science really mean in practice –especially when we wish to achieve.

We hope that this article was helpful in finding the right project for you. By choosing one of the science fair projects listed out in this article, you’ll be well on your way to mastering the basics of that subject. Not only will you be able to develop your technical skills, but you’ll also gain an understanding of the scientific principles at play. If you’re still undecided on what science fair project to choose, explore more information on our website! We’re confident that you’ll find the perfect project for you!

ESA selects four new Earth Explorer mission ideas

As humans exert greater pressure on natural processes, understanding the intricate workings of our Earth system is increasingly vital for effective action on mitigation and adaption strategies. ESA’s Earth Explorer missions yield a wealth of astonishing findings, serving as the bedrock of scientific research in this field. Now, four new concepts have been selected to undergo assessment study, one of which is destined to be the twelfth in this family of world-leading satellite missions.

The selection follows a call for Earth Explorer mission ideas that was issued in early 2023.

From the 17 submissions, which were all thoroughly evaluated, ESA’s Advisory Committee for Earth Observation (ACEO) recommended that four of the ideas should go forward to the assessment study phase.

Today, ESA’s Programme Board for Earth Observation formally accepted this recommendation, which means that the proposed CryoRad, ECO, Hydroterra+ and Keystone mission ideas will now be fully assessed and, in effect, take the first competitive steps towards becoming ESA’s twelfth Earth Explorer.

Simonetta Cheli, Director for ESA’s Earth Observation Programmes, said, “These decisions are always challenging, particularly since the quality of all the proposals that were submitted was very high.

“The mission ideas that will now be further assessed each address key areas of science that would advance knowledge of our Earth system. We thank ACEO and the science community at large for their continuing support in helping us select the best ideas that will fill research gaps and demonstrate new ways of observing our planet from space.”

The four selected mission ideas

CryoRad would fill an important gap in observations of the cryosphere through the direct measurement of low-frequency passive-microwave brightness temperatures using a novel broadband radiometer. From these novel measurements key parameters such as the temperature profile of ice shelves, sea-ice thickness and sea-surface salinity in cold waters can be determined to improve our understanding of key processes in the polar regions. The mission would complement the upcoming Copernicus CIMR, CRISTAL and ROSE-L missions .

ECO would measure the difference between incoming solar radiation and outgoing radiation, which defines Earth’s energy ‘imbalance’, and which fundamentally controls Earth’s climate system. It would be the first time that this imbalance has been measured directly and would help reveal the future trajectory of the climate decades earlier than relying on monitoring global temperature and sea-level rise, as is currently the case. The unique concept envisages a satellite constellation, each carrying four wide field-of-view radiometers to ensure unprecedented coverage, accuracy and stability.

Hydroterra+ would be placed in geostationary orbit, which is unusual for an Earth-science radar mission. From this fixed position above the equator, the satellite’s C-band synthetic aperture radar would deliver data twice a day over Europe, the Mediterranean and northern Africa to understand rapid processes tied to the water cycle and tectonic events in these regions.

Keystone would provide the first direct observations of atomic oxygen in the altitude range of 50–150 km using a unique combination of limb-sounding techniques. These measurements together with observations of composition, temperature and winds would allow scientists to study the processes that drive the variability and energy balance of the mesosphere-lower-thermosphere region of the atmosphere, also looking at the impact of solar cycles and space weather.

These concepts will now undergo assessment phase studies, which will last about 18 months. After this, further down-selections will be made before the successful Earth Explorer 12 mission is selected for implementation.

The family of Earth Explorer research missions are pivotal to ESA’s  FutureEO  programme. Since the successful launch of the first Earth Explorer in 2009, this extraordinary family of missions, without exception, keep on surpassing expectations.

They continue to demonstrate how breakthrough technology can deliver an astounding range of scientific findings about our planet. Their robust technology leads to many being extended way beyond their planned life in orbit and they gain ever-growing user communities through their scientific excellence and open and free data policy.

Importantly, Earth Explorers also provide sound heritage for developing operational missions. For instance, some of the highly successful current suite of Copernicus Sentinel missions and the future Copernicus Sentinel Expansion missions would simply not be possible without the technology and application opportunities demonstrated by the Earth Explorers.

Regulatory Science Challenge

Osseoanchored prosthetics use a permanent bone anchored osseointegrated (OI) implant that penetrates and locks into the long bone inside the body and passes permanently through the skin to the outside to facilitate direct skeletal attachment of external arm and leg prosthetic devices. Such OI implants provide an alternative to traditional socket-based attachment systems and can eliminate issues with skin irritation, ease of applying and removing prosthetics, and improve range of motion. Although certain OI devices have been used internationally for the last decade, the emergence of OI use in the US market is more recent but steadily increasing. While there have been studies that have explored the loads placed on the implant abutment, or support, and consequently the bone and soft tissue to which it is implanted, few of these studies have quantified the loads and forces created during real world use. To date, most measurements of forces between the attached prosthetic and the implant have been interpreted from externally measured forces between the ground and prosthetic foot. Others have used sensing technology in a controlled laboratory and clinical setting whose size and bulk can impact the accuracy of some prosthetic limb movement. This means that the loads experienced by wearers during daily use have yet to be directly determined. Early adopters of OI devices report activities of daily living and recreational activities that are likely creating loads well above what has been measurable to date. Smaller, lighter sensors which can be integrated as part of arm and leg prosthetic systems, attached to the implant, and worn daily can provide critical information to understand the actual implant loads being experienced.

Project Description and Goals

The goal of this project was to design and test a prototype sensor for amputees implanted with OI implants which is small, light, accurate and safe enough to be used day-to-day as part of the total OI prosthetic limb system. The results informed whether a small light load sensor could accurately measure the range of loads placed on an OI implant by a prosthetic limb during real world use and demonstrate a sensor with form and function that can be included as part of the daily prosthetic system. To achieve this, investigators 1) Designed a low profile multi-axial load sensing prototype compatible with real world use; 2) Quantified load sensing ranges relative to overall device size and 3) Validated load sensing responsiveness, accuracy and repeatability in bench top model.

Research Outcomes/Results

JHU CERSI will continue research, development, test and evaluation of the prototype sensor for persistent OI sensor. To date, JHU CERSI has achieved significant progress toward specific aims.

• Design and fabrication of a low-profile load sensing prototype that measures4.5 cm diameter X 2.5 cm high and weighs 3 grams (not including boards and sensors) which is 1.5 and .5 cm smaller than our target and 161 grams lighter.
• Through bench testing, demonstrated the ability to measure multidirectional bending loads up to the maximum load of 70 Nm measured during take home tests with an experimental arm. Please note that experimental features included integrated load sensing capability.
• Validated the persistent load sensor prototype ability to sense loads in two axes: bending loads and torsional(rotational) loads. Sensor prototype accuracy has also been maintained over repeat loading and does so for bending loads up to 35 Nm of torque and 32 Nm of bending load. Both values exceed the max loads expected to be seen in real world upper limb use based on our past research experience.

Overall, investigators, to date, have demonstrated proof-of-concept for a compact lightweight dual axial load sensor prototype capable of measuring loads consistently at load limits higher than expected during real world use ensuring the full range of loads both expected and unexpected are measurable.

Research Impacts

Demonstration of a prototype sensor small and light enough to be integrated as a persistent prosthetic component for amputees with OI implants is the first step in realizing FDA’s regulatory science priority of understanding real world use in general, and specifically to the use of OI implants. This is especially true of upper limb OI implant users. Our prototype demonstrates that the load limits up to those expected in real world upper limb OI users can be captured accurately in a bench top model and in a light, small enough package to be used with upper limb amputees.

The bench top demonstration is the ‘catalyst for future research’ as the foundation required to realize the next steps which include real time communication of measured loads in a closed loop information delivery application. The delivery of load information directly to the patient/wearer of the prosthetic device and capturing information from the patient about the activities being performed. Investigators expect ongoing development to lead to a final design that can inform the goal of establishing targeted rehabilitation protocols, development of methods to encourage rehabilitation exercise compliance, and empowerment of the end user to understand the impact of their activities on device loading.

Huge database gives insight into salmon patterns at sea

A massive new analysis of high seas salmon surveys is enhancing the understanding of salmon ecology, adding details about where various species congregate in the North Pacific Ocean and their different temperature tolerances.

The project, led by researchers at the University of Alaska Fairbanks, integrates numerous international salmon studies from the North Pacific dating back to the 1950s. Although many individual reports were published by nations and agencies that funded those efforts, they were never fully compiled into an overarching database or analyzed comprehensively at this scale. This new research effort builds upon the extensive and valuable past body of work on the marine component of the salmon life cycle.

Together the data represent a trove of more than 44,000 high seas survey gear hauls across the North Pacific, netting over 14 million salmon. That ocean-based data also provides a contrast from the bulk of salmon research, which tends to focus on river habitat.

"This is a portion of the salmon life cycle that arguably gets overlooked, at least in terms of the grand investment in salmon research," said Curry Cunningham, an assistant professor at UAF's College of Fisheries and Ocean Sciences. "As someone who always wondered where all these fish went when they left Bristol Bay, seeing that pattern come to life was so satisfying."

Although methods and data varied among the studies, they consistently noted the water temperature and location where salmon were caught. That data allowed the research team to create maps with unprecedented detail showing the areas that various salmon species occupy while at sea.

For example, the maps highlight a hotspot for Chinooks gathering in the Bering Sea. They chart a path that maturing sockeye tend to take from the North Pacific and Gulf of Alaska toward the Alaska Peninsula, traveling through passes into the Bering Sea outside Bristol Bay throughout the spring and summer.

"It's not as if all these salmon are going to some party in the middle of the Pacific," said lead author Joe Langan, who worked on the project as a postdoctoral fellow at UAF. "This gives us a broad look at where they go."

The study also produced more evidence that cold-water tolerance varies significantly among salmon species. Sockeye and chum salmon were commonly found in temperatures down to just a few degrees above freezing, while coho and steelhead were absent from the coldest areas. Chinook and pink salmon lived in the middle of those ranges.

Those tendencies are likely to influence which species will be most capable of shifting to colder waters as their traditional ranges are warmed by climate change, Cunningham said.

The heart of the dataset is from the 1950s to the 1990s, and the research required digging up forgotten reports from varying sources. Skip McKinnell, a retired Department of Fisheries and Oceans Canada researcher and expert in high seas salmon research, participated in some of the earlier surveys. He helped dredge up, compile and standardize many of those older reports.

"It was more of a search and rescue mission rather than convincing anyone to provide their data," Langan said.

The project was funded by the National Oceanic and Atmospheric Administration's Office of Law Enforcement, which hopes to use information about where salmon are concentrated at sea to help curb illegal fishing. The centralized database will be housed by the North Pacific Anadromous Fish Commission and made publicly available.

New Global Policy Horizons Lab Used to Research Conflict in Yemen

April 17, 2024

• college of humanities and social sciences
• webster groves campus
• history politics and international relations

Samantha Ramay, a history major with a minor in international relations, is tackling a huge research project this year. She is analyzing how diplomatic, economic, military and humanitarian factors are colluding and colliding as part of the unfolding crisis in Yemen and the Red Sea. And she’s using the University’s new Global Policy Horizon Lab to aid her efforts.

“Webster has provided me with academic opportunities I didn't even know existed,” Ramay, a junior who will graduate in 2025, said. “I have been encouraged to pursue challenges outside my comfort zone thanks to the wonderful support I've received from faculty mentors. These interactions in the classroom and beyond have left me inspired and empowered to pursue new paths in my education.”

Her project is focusing on the recent Red Sea attacks being launched out of Yemen by Houthi rebels, allegedly in response to the war in Gaza. She is analyzing the complex web of history, ideology and policies in the Middle East that have contributed to the Yemen crisis. Her final study will be presented as a conflict assessment report that summarizes her findings and offers policy suggestions. Once completed, she will use other resources in the lab to submit the paper for evaluation and publication in a peer-reviewed journal.

“The lab has given me the incredible opportunity to engage in international relations research in the way a policy analyst would, and also be compensated for my research thanks to the Don Maland scholarship for Conflict Analysis and Resolution,” Ramay said. “I am incredibly thankful to be trusted with such a rewarding responsibility.”

The Global Policy Horizon Lab was created with students like Ramay in mind, said International Relations Professor Dani Belo.

“The lab is designed for students from all majors to explore national and international policies, with an emphasis on security,” Belo said. “By using the resources offered in the lab, we hope to equip students the practical knowledge and skills needed to pursue careers in the policy community.”

The lab was launched in the fall of 2023 in Room 104 of the H. Sam Priest Building. While the lab is physically located on Webster’s main campus in St. Louis, it is open to students at all of Webster’s locations around the world, Belo said. “Our resources are all digitally accessible online,” he said. Faculty also can use the lab’s resources, he added. 

Any student who wishes to participate in the Lab should contact Belo at [email protected] and by visiting the Lab website at https://www.webster.edu/humanities-social-sciences/hprr/global-policy-research-lab.php .
