One law to rule them all: Sizes within a species appear to follow a universal distribution
Flocks of birds, schools of fish, and groups of any other living organisms might have a mathematical function in common. Studying aquatic microorganisms, Andrea Giometto, a researcher EPFL and Eawag, showed ...
Human Y chromosome much older than previously thought
(Phys.org) —University of Arizona geneticists have discovered the oldest known genetic branch of the human Y chromosome – the hereditary factor determining male sex.
Viruses can have immune systems, new research shows
A study published today in the journal Nature reports that a viral predator of the cholera bacteria has stolen the functional immune system of bacteria and is using it against its bacterial host. The study provides the fi ...
Shark found to have bioluminescence on both dorsal spine and belly
Fruit flies medicate their larvae with alcohol
Bees and flowers communicate using electrical fields, researchers discover
Flowers' methods of communicating are at least as sophisticated as any devised by an advertising agency, according to a new study, published today in Science Express by researchers from the University of Bri ...
Bigfoot genome sequenced? There are skeptics
Improved-yield dandelions prepped for tire production
Cell circuits remember their history: Engineers design new synthetic biology circuits that combine memory and logic
MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of generations.
Grooming helps insects keep their senses sharpened
Like a self-absorbed teenager, insects spend a lot of time grooming.
Plant geneticists demonstrate new means of boosting maize yields
A team of plant geneticists at Cold Spring Harbor Laboratory (CSHL) has successfully demonstrated what it describes as a "simple hypothesis" for making significant increases in yields for the maize plant.
Mapping the living cell: New technique pinpoints protein locations, helping scientists figure out their functions
To get a clear picture of what's happening inside a cell, scientists need to know the locations of thousands of proteins and other molecules. MIT chemists have now developed a technique that can tag all of ...
Decoded pigeon genome reveals secrets of their traits and origins
University of Utah researchers decoded the genetic blueprint of the rock pigeon, unlocking secrets about pigeons' Middle East origins, feral pigeons' kinship with escaped racing birds, and how mutations give ...
Earthquakes, glue and grappling hooks: Scientists dissect the movement of bacteria
(Phys.org)—A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has discovered that microscopic bacteria have a lot in common with earthquakes—when it comes ...
