A microbe's fountain of youth
The yeast S.pombe is one of the best-studied microbes in the world. First isolated from East African millet beer over a century ago, it's been used as a model organism in molecular and cell biology for the ...
Biologists confirm role of sperm competition in formation of new species
Female promiscuity—something that occurs in a majority of species, including humans—results in the ejaculates from two or more males overlapping within her reproductive tract. When this happens, sperm ...
Second body clock discovered in the speckled sea louse
The diminutive speckled sea louse (Eurydice pulchra) boasts two body clocks, one for night and day and another for the ebb and flow of the tide, according to research published today.
Colonizing songbirds lost sense of syntax: Genes underlying song selection may have been lost in transit
As one species of European songbird island-hopped to colonize mid-Atlantic archipelagoes over the course of a half million years, their songs lost their sense of syntax.
Toxin-producing bacteria integrated into a pest insect
A small cicada-like insect called the Asian citrus psyllid (Diaphorina citri) threatens the world's citrus industries, transmitting an incurable and lethal citrus disease. This notorious pest harbors two ...
Scientists discover important mechanism in plant cells which regulates direction that plant cells grow
Scientists have discovered an important mechanism in plant cells which regulates the direction that plant cells grow.
Ig Nobel Prizes: Why onions make you cry and Enya is bad in the operating room
Let's face it: The Nobel Prizes aren't for everyone. That's why we celebrate the Ig Nobel Prizes, which were handed out Thursday night at Harvard's Sanders Theater.
Study sheds light on genetics of how and why fish swim in schools
How and why fish swim in schools has long fascinated biologists looking for clues to understand the complexities of social behavior. A new study by a team of researchers at Fred Hutchinson Cancer Research ...
A microbe's trick for staying young
Researchers have discovered a microbe that stays forever young by rejuvenating every time it reproduces. The findings, published in Current Biology, provide fundamental insights into the mechanisms of aging.
Darwin's dilemma resolved: Biologists measure evolution's Big Bang
A new study led by Adelaide researchers has estimated, for the first time, the rates of evolution during the "Cambrian explosion" when most modern animal groups appeared between 540 and 520 million years ...
Clues in coral bleaching mystery
Coral reefs are tremendously important for ocean biodiversity, as well as for the economic and aesthetic value they provide to their surrounding communities. Unfortunately they have been in great decline in ...
Identification of a plant-specific nanomachine regulating nuclear movement
A group led by Professor Ikuko Hara-Nishimura (Department of Botany, Graduate School of Science) revealed the molecular mechanism underlying nuclear movement in plants.
On warming Antarctic Peninsula, moss and microbes reveal unprecedented ecological change
By carefully analyzing a 150-year-old moss bank on the Antarctic Peninsula, researchers reporting in Current Biology, a Cell Press publication, on August 29 describe an unprecedented rate of ecological change ...
Evidence that disproves a long-standing assumption about fish development gives insight into evolution of skeletons
A Singapore-based research team has used fluorescent labeling of embryonic cell populations to pinpoint the origin of scales and fins in modern-day fish. These tissues are evolutionary relics of the first ...
