A few bacteria have chemical systems that generate light. This bioluminescence often occurs in bacteria that live in association with fish, and the light probably serves to attract fish or other large animals. Bacteria often function as multicellular aggregates known as biofilms, exchanging a variety of molecular signals for intercell communication and engaging in coordinated multicellular behaviour. The communal benefits of multicellular cooperation include a cellular division of labour, accessing resources that cannot effectively be used by single cells, collectively defending against antagonists, and optimising population survival by differentiating into distinct cell types. For example, bacteria in biofilms can have more than five hundred times the increased resistance to antibacterial agents than individual "planktonic" bacteria of the same species. One type of intercellular communication by a molecular signal is called quorum sensing. Quorum sensing determines whether the local population is dense enough to support investment in processes that are only successful if large numbers of similar organisms behave similarly, such as excreting digestive enzymes or emitting light. Quorum sensing enables bacteria to coordinate gene expression and to produce, release, and detect autoinducers or pheromones that accumulate with the growth in cell population.

Conservation biology is the study of the conservation of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is concerned with factors that influence the maintenance, loss, and restoration of biodiversity and the science of sustaining evolutionary processes that engender genetic, population, species, and ecosystem diversity. The concern stems from estimates suggesting that up to 50% of all species on the planet will disappear within the next 50 years, which has contributed to poverty, starvation, and will reset the course of evolution on this planet. Conservation biologists research the trends of biodiversity loss, species extinctions, and the negative effect these are having on our capabilities to sustain the well-being of human society.

The American Society of Plant Biologists (ASPB) is a non-profit professional society for research and education in plant science. It was founded in 1924 as the American Society of Plant Physiologists (ASPP); the name was changed in 2001. Membership in the society is open to any person from any country who deals with physiology, molecular biology, environmental biology, cell biology and plant biophysics or related issues. It has over 4,000 members worldwide. The society publishes the peer-reviewed journals Plant Physiology (1926–) and The Plant Cell (1989–) as well as ASPB News. The American Society of Plant Biologists also has partnered with the Society for Experimental Biology, and John Wiley & Sons to publish an online-only science journal Plant Direct. In 2000, it published the first edition of the textbook Biochemistry & Molecular Biology of Plants. The first President of the Society was Charles Albert Shull (1924–1925), with founder R. B. Harvey as Secretary-Treasurer. Other presidents of the Society include Harry Beevers (1961–1962), Aubrey Naylor (1960–1961), and Katayoon Dehesh (2021-2022). The first woman to be president of the society was Elisabeth Gantt (1988–1989).

In molecular biology, and more importantly high-throughput DNA sequencing, a chimera is a single DNA sequence originating when multiple transcripts or DNA sequences get joined. Chimeras can be considered artifacts and be filtered out from the data during processing to prevent spurious inferences of biological variation. However, chimeras should not be confused with chimeric reads, which are generally used by structural variant callers to detect structural variation events and are not always an indication of the presence of a chimeric transcript or gene. In a different context, the deliberate creation of artificial chimeras can also be a useful tool in molecular biology. For example, in protein engineering, "chimeragenesis" (forming chimeras between proteins that are encoded by homologous cDNAs) is one of the "two major techniques used to manipulate cDNA sequences". For gene fusions that occur through natural processes, see chimeric genes and fusion genes.

Between 2008 and 2011, Cardona was a Group Leader at the Institute of Neuroinformatics, jointly run by the University of Zurich and ETH Zurich. During this period, he developed computational and image-processing methods for neural circuit reconstruction and co-founded two influential open-source platforms that have become widely adopted in the neuroscience community. Cardona joined the Howard Hughes Medical Institute (HHMI) Janelia Research Campus in 2012, serving as Group Leader until 2019. In 2019, he was appointed Programme Leader at the MRC Laboratory of Molecular Biology and Professor at the University of Cambridge, where he leads research on whole-brain connectomics, circuit development, and structure–function relationships in neural systems.
Cell biology is the branch of biology that studies the structure, function, and behaviour of cells. Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and other metabolic and enzymatic processes that enable the use of energy. Genetics is the scientific study of inheritance. Classical genetics, specifically, is the study of how genes and traits are passed on from parents to offspring; its principles are called Mendelian inheritance. A Punnett square can be used to predict the results of a test cross. The chromosome theory of inheritance, which states that genes are found on chromosomes, was supported by Thomas Morgans's experiments with fruit flies, which established the sex linkage between eye color and sex in these insects.
Chattopadhyay's contributions in membrane and receptor biology and biophysics have been recognized by several awards and prizes. These include The World Academy of Sciences (TWAS) Prize, Shanti Swarup Bhatnagar Award, Ranbaxy Research Award, Prof. G.N. Ramachandran Gold Medal, SERB Distinguished Fellowship, Prof. G.N.

From Greek βίος (bíos) 'life', (from Proto-Indo-European root *gwei-, to live) and λογία (logia) 'study of'. The compound appears in the title of Volume 3 of Michael Christoph Hanow's Philosophiae naturalis sive physicae dogmaticae: Geologia, biologia, phytologia generalis et dendrologia, published in 1766. The term biology in its modern sense appears to have been introduced independently by Thomas Beddoes (in 1799), Karl Friedrich Burdach (in 1800), Gottfried Reinhold Treviranus (Biologie oder Philosophie der lebenden Natur, 1802) and Jean-Baptiste Lamarck (Hydrogéologie, 1802).
