Earth’s most diverse biological entities are the viruses that infect bacteria, called bacteriophages (phages). They are rich resources for discovering proteins and tools for biotechnology, but many ...

A new study in fruit flies describes how an animal's gut reacts differently to beneficial microbes versus harmful pathogens.

These chains come in a wide range of lengths. In humans a typical protein is about 400 amino acids long; some are a lot longer. Molecules of RNA, one of the two nucleic acids, can reach up to 100,000 ...

Glioblastoma, an aggressive brain cancer, depends on the amino acid serine as a fuel source. A serine-deficient diet has been shown to slow tumour growth in mice. Daniel Mobilio is in the Centre for ...

Every new life begins after a genetic shuffle. When organisms make eggs or sperm, maternal and paternal chromosomes pair up and swap pieces of DNA in a process called crossing over.

Biologists and computational scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory recently refined two artificial intelligence (AI) programs originally built by Meta, the ...

For decades, amino acids have been added to medical formulations like insulin as stabilizers: these small molecules keep proteins (i.e. larger particles) from interacting in undesirable ways. And for ...

On Jan. 10, Chinese scientists uploaded the genetic sequence of a novel coronavirus, later named SARS-CoV-2, to an open-access website, GenBank. The virus had been linked to a growing number of ...

Inherited metabolic diseases are rare monogenic conditions that disrupt biochemical pathways, affecting energy production and homeostasis, often leading to damaging metabolite acc ...

Proteins Bind to Metals Necessary for Life Proteins start off as long strands of smaller molecules called amino acids, linked together like beads on a string. But before these molecules can do their ...

Balance sheets illustrate a company's financial stability via assets and liabilities. The acid-test ratio measures liquidity, with values over 1 indicating strong liquidity. High acid-test ratios ...
