By Manipulating Oxygen, Scientists Coax Bacteria Into Never-Before-Seen Solitary Wave
Bacteria know that they are too small to make an impact individually. So they wait, they multiply, and then they engage in behaviors that are only successful when all cells...
Researchers study 'fundamental, amazing change' in Great Lakes (w/ Video)
(PhysOrg.com) -- The Great Lakes are in the midst of a remarkable ecological transformation, driven largely by the blitzkrieg advance of two closely related species of non-native mussels.
Sex found involved in plant defense
RALEIGH, N.C., July 15 (UPI) -- U.S. biologists say they've determined some sexually produced plants better withstand insect attacks than do asexually produced plants.
New Doubts About Fasting Leading To Longer Lives Based On Study In Flies
Many studies indicate that caloric restriction extends life spans in fruit flies, mice and, most recently, rhesus monkeys, apparently by slowing the aging process. But virtually all these studies have...
LincRNAs serve as genetic air-traffic controllers
Earlier this year, a scientific team from Beth Israel Deaconess Medical Center (BIDMC) and the Broad Institute identified a class of RNA genes known as large intervening non-coding RNAs or...
New theory on why male, female lemurs same size
When it comes to investigating mysteries, Sherlock Holmes has nothing on Rice University biologist Amy Dunham. In a newly published paper, Dunham offers a new theory for one of primatology's...
Study catches 2 bird populations as they split into seperate species
A new study finds that a change in a single gene has sent two closely related bird populations on their way to becoming two distinct species. The study, published in...
Smaller plants punch above their weight in the forest
New findings from Queen's University biologists show that in the plant world, bigger isn't necessarily better...
Mathematics taking guesswork out of plastic surgery tissue transfer
Plastic surgeons are turning to mathematics to take the guesswork out of efforts to ensure that live tissue segments that are selected to restore damaged body parts will have enough...
Bird population declines in northern Europe are explained by thiamine (vitamin B1) deficiency
Wild birds of several species are dying in large numbers from a paralytic disease with hitherto unknown cause in the Baltic Sea area. A research team at Stockholm University, Sweden,...

Flexible neck in cell-receptor DC-SIGN targets more pathogens
Pathogen recognition is the foundation of the body's immune response and survival against infection. A small cell-receptor protein called DC-SIGN is part of the immune system, and recognises certain pathogens,...
Big "Transsexual" Fish in Peril
A favorite of divers in Australia, the blue groper grows to about three feet (one meter) long and can change its own sex. But its numbers are diving, and researchers are trying...
Eat up! Calorie restriction may weaken the immune system
Going hungry helps lab animals live longer, but for people like you and me living in the real world it could have the opposite effect, warns Jacob Aron
Study provides important insight into apoptosis or programmed cell death
A study by Nanyang Technological University (NTU)'s Assistant Professor Li Hoi Yeung, Assistant Professor Koh Cheng Gee and their team have made an important contribution to the understanding of the...
