(Phys.org) —If you asked a biologist what any given cell is going to do next, they might ask you first to tell them its electrical potential, oxygenation, pH, osmolarity or glucose concentration. Depending on how finely-scaled ...
(Phys.org)—Throughout her career, the famous biologist Lynn Margulis (1938-2011) argued that the world of microorganisms has a much larger impact on the entire biosphere—the world of all living things—than scientists typically ...
(Phys.org)—Of the many microbes that – like almost all life – require iron, some live in iron-limited environments. What to do? Secrete siderophores, of course: small, high-affinity iron chelating compounds that scavenge ...
(Phys.org)—Biological systems are characterized by a form of molecular recycling – and proteins do not escape this fate. In particular, unneeded or damaged proteins biochemically marked for destruction undergo controlled ...
(Phys.org)—Synthetic biology combines science and engineering in the pursuit of two general goals: to design and construct new biological parts, devices, and systems not found in nature; and redesign existing, natural biological ...
(PhysOrg.com) -- The effort to classify life into various groups has been a bumpy ride. Prior to the 1900s, living things were usually pegged as either plants or animals – period. By the middle of the 20th century, ...
Researchers at the Massachusetts Institute of Technology (MIT) have discovered thousands of new proteins that protect bacteria from virus attacks using an AI system called DefensePredictor. What would usually take months ...
We are continually in an evolutionary arms race with bacteria. As we develop new antibiotics, they develop resistance, and so it goes on until some of our treatments no longer work. Superbugs and antimicrobial resistance ...
Some of the most ancient fossils collected to date were traced back to the Ediacaran period. This is the time interval ranging from around 635 to 541 million years ago, shortly before the time when scientists predict that ...
A multi-institutional team of scientists, co-led by Northwestern University, has taken a crucial step toward implantable "living pharmacies"—tiny devices containing engineered cells that continuously produce medicines inside ...
