Diatom genome sizes predict abundance

Body size is a fundamental predictor of organismal abundance, and larger-bodied organisms predominate in colder areas ("Bergmann's rule"). A study of diatoms by Wade Roberts, Adam Siepielski and Andrew Alverson reveals that in these unicellular organisms, genome size, rather than cell size, is a strong predictor of species abundance in the polar oceans.

A Guide to the Types of Biological Research

Published on: January 2, 2024

Even if you are keenly interested in biology and life sciences, you may be unfamiliar with the various research branches in these fields and the specific biological research topics that captivate scientists today. After offering some fundamental information about the vital research of biologists, this guide highlights 18 different types of biological research.

Importance of Biological Research

If you’ve ever asked yourself a fundamental question about human, animal or plant life on this planet, a biologist has likely conducted a study to answer it. Few branches of science are broader or more varied than biology — an ancient yet vital scientific discipline that has led human beings to a far greater understanding of life in all its forms. Biology has also enabled us to make tremendous strides in terms of protecting and preserving life.

Fueled by critical scientific breakthroughs such as the discovery of DNA structure in the mid-1900s, research in biology has yielded countless medical discoveries that have both improved and saved the lives of countless people. From drug development to disease prevention, significant medical advances would not have come to be without extensive biological research.

And this is only the tip of the iceberg when it comes to the benefits of biological research. From supporting environmental conservation and sustainability to the growth of food and management of livestock, few areas of human advancement are left untouched by biologists and their work. The field has even answered many fundamental existential questions by uncovering the theory of evolution and generally advancing our understanding of the natural world.

18 Types of Biological Research

Today’s biology research topics are tackling some of the heaviest that humanity faces, including many that involve our very existence. Read on for brief introductions to fields of research that are shaping the future of biology as we know it.

1. Developmental Biology

Developmental biology focuses on how a life form develops. For example, a developmental biologist might study the ways in which a single-cell embryo divides into an organized group of cells that then become genetically “programmed” at specific stages for purposes and tasks. Although an organism’s DNA dictates much of its development, environmental factors also play a critical role. Beyond basic cellular function and differentiation, developmental biologists work on studies that focus on subjects such as the repair of damaged tissue and the broad clinical uses for stem cells.

2. Evolutionary Biology

Issues connected to molecular mechanisms of DNA are essential to the work of evolutionary biologists as well. However, this discipline is specifically concerned with the transfer of genetic information through generations. In addition to charting the biological adaptation and diversification of life throughout history and pre-history, evolutionary biology investigates the origin of life on Earth.

3. Computational Biology

Also known as “bioinformatics,” computational biology bridges the gap between biology and digital technology by developing and applying computational methods and software tools to analyze massive sets of biological information. The effective handling of big data can prove helpful when it comes to identifying and analyzing complex biological factors that range from genetic sequences to organism populations. To make accurate predictions and determine outcomes, computational biologists often use mathematical modeling and computer simulations.

4. Cellular Biology

True to its name, cellular biology concentrates on the cell as the fundamental unit of functional life on this planet. Cellular biology research may concern any or all aspects of cell anatomy and cell processes that range from respiration to mitotic and meiotic division. It is important to note that cellular biology, like many of the biology research specializations on this list, doesn’t exist in a vacuum. In fact, cellular biologists might perform research that involves genetics, biochemistry, molecular biology and numerous other related areas of study.

5. Immunology

Like the vast majority of living things, human beings possess immune systems that protect us from pathogens as well as other foreign entities and substances that might enter our bodies and threaten our health. These immune systems are both innate (organisms are born with immune systems) and adaptive (immune systems respond to meet the changing needs of the organism).  Medical Life Sciences News  defines immunology as the branch of biological science that studies the body’s ability to recognize “what is self and what is not.” This recognition allows the body to attack pathogens to preserve its vital internal structures and processes. Some research in the field of immunology examines what happens when the body mistakes healthy cells for foreign invaders.

Whereas many branches of biological research look inward to study structures and processes within the organism, ecological research examines how living things function within their environments and interact with various environmental stimuli. Ecological researchers ask questions such as, “What is the relationship between organisms and their habitats?” and “What environmental elements allow different organisms to not only survive but also thrive?”

7. Biophysics

Succinctly defined by the  Biophysical Society , biophysics is “the field that applies the theories and methods of physics to understand how biological systems work.” Furthermore, the field of biophysics bridges the gap between physics and diverse subbranches of biological study. Research projects in biophysics might investigate how molecules essential to life develop; how the various components of a cell interact; and how immune, nervous, circulatory and other bodily systems function. Beyond biology and physics, biophysical researchers may draw upon any number of other scientific disciplines including mathematics, engineering, chemistry and materials science.

8. Physiology

Another biological field that intersects and overlaps with many others, physiology studies the mechanisms and functionality of living things. To better understand these mechanisms and their functions, physiological researchers commonly examine how component parts, such as organs and cells, operate internally and interact with one another. Although the technology and methodology used to conduct physiological study has grown by leaps and bounds over the years, this branch of science is among the oldest in the field of biology. In fact, the origins of physiology have been traced back to 420 BC or earlier.

9. Biochemistry

As its name implies, biochemistry focuses on the intersection of biology and chemistry, specifically the chemical processes that occur within living things. Commonly conducted in a laboratory setting, biochemical researchers study the composition and structure of chemicals within organisms as well as the ways in which these chemicals react with one another, affect, and drive different biological processes. By optimizing healthy chemical reactions and correcting unhealthy ones, experts in this field can apply their research to a wide range of medical issues.

10. Microbiology

While most people understand that microbiologists conduct biological research at the microscopic level, fewer realize that they actually study microbes. Otherwise known as “microorganisms,” microbes are living organisms that are too small to see with the unaided eye. They include viruses, bacteria, fungi, algae, protozoa, prions and archaea. As the immunologist knows all too well, many microbes can prove dangerous and even fatal when they enter the human body. By identifying and analyzing these pathogens at the molecular level, microbiologists can develop ways to combat them. The  Microbiology Society  also lists “the manufacture of biofuels, cleaning up pollution and producing/processing food and drink” among microbiology’s most promising and effective applications.

11. Entomology

Simply put, entomology is the study of insects. Although they are just one of four classes of arthropods (animals with exoskeletons), insects are tremendously important to human beings for a variety of reasons. A large concentration of research goes into controlling the harmful effects of insects in terms of food production and disease prevention. The Insecta class is also worth studying for its sheer size; the number of insects on the planet today far exceeds that of any other type of living thing. Though there are likely many insects left to be discovered, scientists have documented more than a million insect species to date. This means that insects alone comprise roughly 40 percent of all living species known to exist.

12. Structural Biology

Structural biology examines the structure, assembly, function and interaction of biological molecules. It is generally concerned with proteins because this particular class of molecules is so prevalent in living things, especially animals. For this reason, proteomics (the study of the biological proteins) comprises a great proportion of the structural biologist’s work. Many structural biology studies concentrate on identifying and addressing misshapen protein molecules that might lead to disease.

13. Genetics

Because it provides a “blueprint” for building the molecules that comprise all life on Earth, DNA is essential in nearly all fields of biological study. As the study of genes and heredity, genetics examines the ways in which certain characteristics in living things pass through generations from parents to offspring. Genetic mutations can cause both dramatic improvements and dangerous deficits in the overall health and well-being of an organism. Genetic research can do everything from determining a person’s likelihood of developing a specific disease to creating therapeutic remedies for that disease.

14. Genomics

Genomics is closely related to the field of genetics and often considered one of its subfields. But while classical genetics tends to study a single gene or gene expression at a time, genomics studies the genomes of organisms in their entirety. This was impossible before the advent of modern genome mapping technologies and techniques such as those employed by the  Human Genome Project , which identified the precise order of the 3 billion DNA subunits that comprise the human genome.

15. Zoology

Although zoologists often study human beings as part of the larger animal kingdom, they primarily study non-human animals, both domestic and wild. Zoology researchers might conduct wildlife studies for government agencies or nonprofit organizations. With specialized clinical training, these professionals can also conduct crucial veterinary research.

16. Marine Biology

You probably already knew that marine biologists deal with the underwater world — but did you know their areas of expertise are restricted to life in oceans and other saltwater environments? Although it doesn’t cover freshwater animals, if you want to “do a deep dive” on sea life, marine biology research may be the path for you. It is a rich and multifaceted field that can allow you to focus on specializations ranging from marine ecology to fishery science.

Just as the zoologist studies the animal kingdom, the botanist studies the plant kingdom. An equally wide and varied field, botany encompasses all aspects of plant life study including (per Biology Online ), “morphology, anatomy, cell biology (branch dealing with plant cells), molecular biology, biochemistry, physiology (deals with phenomena related to plant growth), economic and ethnic aspects, taxonomy, environmental science, genetics, genomics, etc.”

18. Molecular Biology

A close cousin to structural biology and biochemistry, molecular biology examines the molecular basis for biological activity. Because all matter and living things are made of molecules, the molecular biologist can learn a great deal about living things by studying their molecules and how they interact.

Context Matters for Foundation Models in Biology

Just as words can have multiple meanings depending on the context of a sentence, proteins can play different roles in a cell based on their cellular environments. Advances in our understanding of protein and biomolecule functions have been propelled by recent breakthroughs in transformer-based models, such as large language models and generative pre-trained transformers, which automatically learn word semantics from diverse language contexts. Innovating a similar approach for protein functions—viewing them as distributions across various cellular contexts—could enhance the use of foundation models in biology. This would allow the models to dynamically adjust their outputs based on the biological contexts in which they operate. To this end, we have developed PINNACLE , a novel contextual AI model for single-cell biology that supports a broad array of biomedical AI tasks by tailoring its outputs to the cell type context in which the model is asked to make predictions. 

To glean the meaning of a word, we examine nearby words for context clues. For example, “buy an apple” and “grow an apple” yield different recommendations: the first phrase is used to refer to apple products, whereas the second is better associated with apple trees (Figure 1a). To resolve the role of a protein, we interrogate it in the context of the proteins with which it interacts and the cells in which it exists. For instance, H2AFX is a gene that can be involved in homologous recombination or end joining depending on its cellular context (Figure 1b).

Cellular context is critical to understanding protein function and developing molecular therapies. Still, modeling proteins across biological contexts, such as the cell types that they are activated in and the proteins they interact with, remains an algorithmic challenge. Current approaches are context-free: learning on a reference context-agnostic dataset, a single context at a time, or an integrated summary across multiple contexts. As a result, they cannot tailor outputs based on a given context, which can lead to poor predictive performance when applied to a context-specific setting or a never-before-seen context. We develop PINNACLE, a new geometric deep learning approach that generates context-aware protein representations to address these challenges.

Context-specific geometric deep learning PINNACLE model

PINNACLE is a novel geometric deep learning model that learns on contextualized protein interaction networks to produce 394,760 protein representations from 156 cell type contexts across 24 tissues. By leveraging a multi-organ single-cell atlas Tabula Sapiens from CZ CELLxGENE Discover , we construct 156 cell type specific protein interaction networks that are maximally similar to the global reference protein interaction network while maintaining cell type specificity (left and middle panels of Figure 2). We additionally create a metagraph to capture the tissue hierarchy and cell type communication among the cell type specific protein interaction networks (right panel of Figure 2). There are four distinct edge types in the metagraph: cell type to cell type (i.e., cell type interaction), cell type to tissue, tissue to cell type (i.e., tissue membership of the cell type), and tissue to tissue (i.e., parent-child tissue relationship in a tissue ontology). This results in multi-scale networks representing protein, cell type, and tissue information in a unified data representation.

PINNACLE’s algorithm specifies graph neural message passing transformations on multi-scale protein interaction networks . It performs neural message passing with attention for each cell type specific protein interaction network (component 1 in Figure 3) and metagraph (component 2 in Figure 3), and aligns the protein and cell type embeddings using an attention bridge (component 3 in Figure 3). First, PINNACLE learns a trainable weight matrix, node embeddings, and attention weights for each cell type specific protein interaction network. They are optimized based on two protein-level tasks: link prediction (i.e., whether an edge exists between a pair of proteins) and cell type identity (i.e., which cell type a protein is activated in). Secondly, on the metagraph, PINNACLE learns edge type specific trainable weight matrices, node embeddings, and attention weights and aggregates the edge type specific node embeddings via another attention mechanism. These trainable parameters are optimized using edge type specific link prediction (i.e., whether a specific type of edge exists between a pair of nodes). Thirdly, PINNACLE learns attention weights to bridge protein and cell type embeddings. This attention bridge facilitates the propagation of neural messages from cell types and tissues to the cell type specific protein embeddings. It enables PINNACLE to generate a unified embedding space of proteins, cell types, and tissues. Further, the attention bridge enforces cellular and tissue organization of the latent protein space based on tissue hierarchy and cell type communication, enabling contextualization of protein representations.

Context-specific predictions

PINNACLE’s contextual representations can be adapted for diverse downstream tasks in which context specificity may play a significant role. Designing safe and effective molecular therapies is one such task that requires understanding the mechanisms of proteins across cell type contexts. We hypothesize that, in contrast to context-free protein representations, contextualized protein representations can enhance 3D structure-based protein representations for resolving immuno-oncological protein interactions (Figure 4) and facilitate the investigation of drugs’ effects across cell types (Figure 5).

Contextualizing 3D molecular structures of proteins using existing structure-based models is limited by the scarcity of structures captured in context-specific conformations. We show via demonstrative case studies that PINNACLE’s contextualized protein representations can improve structure-based predictions of binding (and non-binding) proteins (Figure 4a). For two immuno-oncological protein interactors, PD-1/PD-L1 and CTLA-4/B7-1, we generate embeddings of each protein using a state-of-the-art structure-based model, MaSIF. We aggregate these structure-based embeddings with a corresponding genomic-based context-free or contextualized protein embedding (i.e., from PINNACLE). By calculating a binding score (i.e., cosine similarity between a pair of protein embeddings), we find that contextualized embeddings enable better differentiation between binding and non-binding proteins (Figure 4b). This zero-shot analysis of contextualizing 3D structure-based representations exemplifies the potential of contextual learning to improve the modeling of molecular structures across biological contexts.

Nominating therapeutic targets with cell type resolution holds the promise of maximizing the efficacy and safety of a candidate drug. However, it is not possible with current models to systematically predict cell type specific therapeutic potential across all proteins and cell type contexts. By finetuning PINNACLE’s contextualized protein representations, we demonstrate that PINNACLE outperforms state-of-the-art, yet context-free, models in nominating therapeutic targets for rheumatoid arthritis (RA) and inflammatory bowel diseases (IBD). We can pinpoint cell type contexts with higher predictive capability than context-free models (Figure 5a). In collaboration with RA and IBD clinical experts, we find that the most predictive cell types are indeed relevant to RA and IBD. Further, examining predictions of individual proteins across cell types allows us to interrogate each candidate target’s therapeutic potential in each cell type context.

PINNACLE is a contextual AI model for representing proteins with cell type resolution. While we demonstrate PINNACLE’s capabilities through cell type specific protein interaction networks, the model can easily be re-trained on any protein network. Our study focuses on single-cell transcriptomic data of healthy individuals, but we expect that training disease-specific PINNACLE models can enable even more accurate predictions of candidate therapeutic targets across cell type contexts. PINNACLE’s ability to adjust its outputs based on the context in which it operates paves the way for large-scale context-specific predictions in biology.  

PINNACLE exemplifies the potential of contextual AI to mimic distinctly human behavior, operating within specific contexts. As humans, we naturally consider and utilize context without conscious effort in our daily interactions and decision-making processes. For instance, we adjust our language, tone, and actions based on the environment and the people we interact with. This inherent ability to dynamically adapt to varying contexts is a cornerstone of human intelligence. In contrast, many current biomedical AI models often lack this contextual adaptability. They tend to operate in a static manner, applying the same logic and patterns regardless of differing biological environments. This limitation can hinder their effectiveness and accuracy in biological systems where context plays a crucial role.

By integrating contextual awareness, models such as PINNACLE can transform biomedical AI. We envision that context-aware models will dynamically adjust their outputs based on the specific cellular environments they encounter, leading to more accurate and relevant predictions and insights. This advancement enhances the functionality of AI models in biology and brings them a step closer to emulating the nuanced and adaptable nature of human thought processes.

Funding Not all labs will have immediate funding to support all the interested undergraduates. However, Mentored Research (Bio494R) or Introduction to Mentored Research (Bio194) are excellent ways to get started in a lab. Often a professor will eventually pay students helping them with research. In some rare cases, professors don't provide financial compensation. One remedy is the College Undergraduate Research Awards (CURA). These are grants given exclusively to undergraduate students to help foster and encourage research. More information is available at http://lscura.byu.edu.

Ecology is the study of how living organisms, including humans, interact with each other and their physical environment. Students and faculty in the Biology Department study the ecology of organisms at multiple levels or organization; from individuals, populations, communities, and ecosystems, to the entire biosphere (global ecology). The study of ecology intersects with several closely related fields, including biogeography, biodiversity, evolutionary biology, developmental biology, physiology, genetics, animal behavior, geology, biochemistry, anthropology, and paleontology.

Currently, the Earth is being transformed at a high rate and in unprecedented ways. Human activities are causing widespread habitat loss and degradation, pollution, invasive species, land-use changes, and climate change. Human health and welfare depend on our ability to understand and mitigate these changes. Thus, the study of ecology has become one of the most critical and dynamic fields in all of the biological sciences.

Do we really need more ecologists? Yes! Fundamental principles of ecology are used to inform applications and careers in conservation biology, conservation genetics, wetland management, agriculture, forestry, fisheries, wildlife management, urban planning and human ecology, community health, emerging infectious diseases, epidemiology, and economics.

As the Earth faces mounting pressure to meet the needs of our growing population, people with an understanding of ecological principals and how to apply them to sustain life will wield the most important skills we’ll need to navigate our uncertain future.

Evolutionary Biology is a sub-discipline in Biology that studies the forces that shape earth's variety of life forms, or biodiversity. There are several different forces or mechanisms that drive evolution. Natural selection is one of these major forces (and perhaps the most well-known), but there are others, including mutation, genetic drift, migration, and nonrandom mating. Collectively, these mechanisms influence how populations of organisms change over time -- how they evolve. One of the central tenets of evolution is that different species share common ancestry. Similar to how a family tree illustrates how individuals are descended from or related to others, the many species that currently live on the earth are related by descent from common ancestors. Evolutionary biology uses morphological (structural features of an organism), ecological, molecular, geographical, and behavioral data to study species relationships and understand what our planet's biodiversity used to be, how it became what it is now, and even make predictions about what it will look like in the future. As the unifying theory in Biology, evolution helps scientists understand more about the living things around us.

Education research, broadly, refers to the study of education and learning. Education researchers may focus on individuals, groups/classes, instructors, institutions and their interactions to investigate how they impact formal or informal teaching and learning. Biology education research is a type of discipline-based education research, where education research is conducted in the context of a specific field (its worldview, knowledge, and practices) and by content experts. Faculty and students in the Biology Department use their biology content expertise as well as training in broad learning theories and pedagogy to inform their biology education research. Discipline-based education research can focus on K-12 education, higher education, or informal education, although faculty in the Biology Department primarily focus on higher education.

Biology education research can answer a broad range of questions using a diverse set of methods. Goals of biology education researchers may include testing specific learning theories and constructing new models of effective teaching and learning in biology contexts, developing and testing evidence-based practices to improve biology teaching and learning, investigating the nature of biology expertise in specific sub-disciplines and how that expertise is developed, studying the experiences of marginalized groups in science and proposing practices to broaden participation and success, and more. Researchers may use experimental, quasi-experimental, observational, or design-based methods, and they may use quantitative and/or qualitative analysis techniques depending on the research question.

Biology education research is an exciting field that allows students to learn more about effective teaching and learning in the context of biology topics they are learning about in their coursework. Students also develop scientific skills such as study design, data collection, statistical and/or qualitative analysis, and written and verbal science communication.

At BYU we have professors and researchers working with insects and their relatives in all these ways. BYU offers several courses where insects are the exact focus of the entire class and most classes in biology include them or should include them in the general

Entomology is the study of insects and their relatives. Flies, beetles, lacewings, bees, ants, centipedes, butterflies, dragonflies, and earwigs are all fair game for study. Our best estimates show 1.5 million species have been given names, more than all other animals combined. Related estimates are that only 10% of the species of insects on Earth have been given formal scientific names. So much more basic work needs to be done, if only to name them.

In addition to this taxonomic richness, they play key parts in most ecosystems and their inherent diversity makes them model organisms for all biologists in the study of evolution, genetics, ecology, and physiology. An entomologist is a person who studies these diverse animals using morphological, molecular, and behavioral techniques.

Insects are beautiful and many have been recognized in human culture as sources of both admiration and disdain. Consider the paintings, poetry, scriptures, and windshield smashes you have seen, read, or heard.

But wait, on the positive side insects are extremely important as pollinators of much of our human food and provide direct food for humans in the form of honey. Their entire bodies are eaten and relished in many cultures.

On the negative side insects destroy large proportions of the food we would like to eat with our burgeoning populations. Insects also pass on smaller organisms that cause disease for our own human bodies. The diseases they carry can harm the crops, pets, livestock, forests, lawns, and wildlands we cherish.

Insects can be studied for their own sake. Scientists refer to this as basic research. Outcomes of basic research may or may not yield solutions to human problems: the goal here is increasing overall knowledge. And yet those increases might be used later in solving problems. . .

And of course, we need to study insects to discover their roles in enhancing and harming humans. This is called applied research where an exact insect situation is studied with goals to find ways to either control the bad outcomes or enhance the good ones.

Plant biologists study the many fascinating aspects of green life! As the only organisms with the ability to take carbon dioxide gas and turn it into carbohydrates, plants form the basis of our diets, provide feed for livestock, fuel our modern amenities (yes, coal and oil are just dead plants), make up the fibers in our clothing, give us lumber for building, and are the source of many pharmaceuticals.

Plant biologists are involved in many interesting areas. Plant taxonomists seek to understand the relationship between plant species and often discover new ones. They often also catalog the natural world to help us understand where specific plants are found. Plant geneticists seek to understand the genetic mechanisms by which plants grow and develop their individual traits. Geneticists are involved in helping us understand the fundamental basis of life, and they also do important work developing healthier, more sustainable crops. Plant biologists’ work often overlaps with ecologists, evolutionary biologists, bioinformaticians, molecular biologists, chemists, agronomists, and farmers.

So, whether you are looking to get your hand dirty, work with cutting edge science, or both, plant biology is a great place to be!

The incredible diversity of life on earth is invaluable. It is the key to adaptation to changes, creates resilient ecosystems, provides foundational ecosystem services, can broaden our perspective of the complexities of the world around us, and provides opportunities for spiritual growth and connection. While doing research, students are prepared to (1) understand principles that influence biodiversity, particularly those that create and those that reduce it, (2) document and preserve the diversity of life on the planet, in addition to the ecosystem services they support, and (3) develop a more comprehensive perspective of the world around us by considering the range of all life.

Human activities are presently causing widespread habitat loss and degradation, pollution, invasive species, land-use changes, and climate change. These activities have resulted in what is called the “Sixth Mass Extinction”, with estimated extinction rates at 100 to 1,000 times higher than the background rate. Human health and welfare depend on our ability to understand and mitigate these changes. Beyond human health, protecting earth’s diversity comprises foundational ethical and spiritual dimensions. Thus, the study of biodiversity and conservation has become one of the most critical, relevant, and dynamic fields across all disciplines.

Students and faculty in the Biology Department study biodiversity and conservation at multiple levels - from genetic diversity (the variety of genetic information contained in all organisms) to species diversity (the variety of different living species) to ecosystem diversity (the variety of habitats, the species that live in the habitat, and ecological processes). Here, our study of biodiversity and conservation intersects with several closely related fields, including biogeography, ecology, evolutionary biology, developmental biology, physiology, genetics, geology, biochemistry, and others.

Students are encouraged to engage in original, transformative research. With dedicated, passionate faculty mentors, students can explore topics ranging from documenting diversity to improving conservation and management strategies to developing improved educational practices to promote biodiversity and conservation. As we face mounting pressure to envision new ways to protect, promote, and value earth’s biodiversity, people with an understanding of biodiversity and principals of conservation will wield the most important skills we’ll need to navigate our uncertain future.

Bioinformatics research has several focus areas including (but not limited to) using machine-learning algorithms to clarify relationships between molecular measurements in tumors and cancer-patient outcomes, building software tools to aid biologists in their efforts to analyze biological data, and identifying pedagogical approaches that enable students to learn fundamental bioinformatics and biostatistics skills. Students in bioinformatics labs work on a variety of projects. Some projects are hypothesis driven and focus on analyzing data (typically from public repositories). Other projects are software focused--students write code and create open-source software. Other projects are experiment-driven, especially using classroom interventions to try new teaching techniques.

Shining light on dinoflagellate photosystem I

Dinoflagellates are ecologically important and essential to corals and other cnidarians as phytosymbionts, but their photosystems had been underexplored. Recently, photosystem I (PSI) of dinoflagellate Symbiodinium sp. was structurally characterized using cryo-Electron Microscopy (cryo-EM). These analyses revealed a distinct organization of the PSI supercomplex, including two previously unidentified subunits, PsaT and PsaU, and shed light on interactions between light harvesting antenna proteins and the PSI core. These results have implications with respect to the evolution of dinoflagellates and their association with cnidarians.

Restoration as a meaningful aid to ecological recovery of coral reefs

Restoration supports the recovery of ecological attributes such as cover, complexity, and diversity to slow the areal decline of natural ecosystems. Restoration activity is intensifying worldwide to combat persistent stressors that are driving global declines to the extent and resilience of coral reefs. However, restoration is disputed as a meaningful aid to reef ecological recovery, often as an expensive distraction to addressing the root causes of reef loss. We contend this dispute partly stems from inferences drawn from small-scale experimental restoration outcomes amplified by misconceptions around cost-based reasoning. Alongside aggressive emissions reductions, we advocate urgent investment in coral reef ecosystem restoration as part of the management toolbox to combat the destruction of reefs as we know them within decades.

Additionally, the topic should have a significant impact or relevance in the current state of the field. This involves considering the interests of potential readers or the audience, ensuring that the topic is not only of personal interest but also of broader academic or societal importance.

Furthermore, the selection process should involve an assessment of the current state of knowledge in the field. This includes reviewing recent advances, perspective-changing publications, and ongoing debates within the discipline. A good research topic often lies at the intersection of what is currently known and the unexplored or less understood aspects of the field. By focusing on these areas, your research paper examples can contribute to the advancement of knowledge, offering new insights or solutions to existing problems. In summary, the ideal research topic is one that sparks personal interest, addresses a gap or a pressing question in the field, and has the potential to contribute meaningfully to the broader academic community.
