Overfishing may drive endangered seabird to rely upon lower quality food

...greater selection of time periods to get a clearer picture of impacts of oceanic conditions and fishing pressure throughout the past century. ...

Phenotype is influenced by nature, nurture and noise

...ls in a single flask of growth medium. The mental picture most biologists have of a cell is of a smoothly running Swiss watch," said Hasty. "But our results and the findings of other theorists and computational biologists are proving otherwise. The fine-grain fluctuations we see in the genetic regulation wi...

Limiting the damage in stroke

... together permitted the researchers to get a clear picture of IKK2's role after a stroke. Mice with the hyperactive form of IKK2 in neurons and too much NF-kB signalling, they discovered, suffer even more damage than normal; far more cells die. But if the IKK2 signal is blocked, damaged cells stay alive an...

Jefferson biologist coaxing human embryonic stem cells to make dopamine with simpler, faster method

...s are avoided and a PET scan can give clinicians a picture not only of an afflicted part of the anatomy, but of the whole body over time and in a way that portrays the body's response to disease as it happens. PET is already a widely used technology. In conventional clinical settings it produces images of t...

PET imaging reveals the immune system at work

Looking for the genes that affect a person's level of response to alcohol

...ssible age they could give informed consent as the picture is clearest when they're youngest. When people get older, they get fatter, they change their percent body water, which changes their reaction per drink, their liver gets a little slower in metabolizing alcohol, their brain gets a little more sensiti...

Free-energy theory borne out in large-scale protein folding

...s of statistical mechanics, building up an overall picture of MLAc folding based upon statistical approximations of molecular events. On the experimental side, Wittung-Stafshede, Matthews and Wilson prepared samples of MLAc and added urea to cause them to unfold. The team then injected water into the soluti...

Scientists map one of biology's critical light-sensing structures

...ng a beam of X-rays to develop a three-dimensional picture of the protein. That three-dimensional portrait, which reveals the atom-by-atom configuration of the molecule, is the key to understanding the "nuts and bolts" of how the photoreceptor senses light and triggers a series of downstream events that cont...

Brain activity related to processing faces is similar in people with, without autism

... or right, thereby requiring that they look at the picture of the face," Dichter said. In addition, Belger and Dichter pointed to research that correlated the amount of time autistic people looked at features of a face with activation of the amygdala, the "anxiety center" of the brain. They propose that th...

Researchers identify molecular anchor that allows bacterial invasion of central nervous system

... all of these factors in order to paint a complete picture of how the bacteria invade the brain and spinal cord to produce this potentially devastating infection. Bacterial meningitis must be treated quickly and aggressively with antibiotics, since up to 25 percent of affected children may die or suffer per...

U. of Colorado researcher identifies tracks of swimming dinosaur in Wyoming

... The video and related studies help paint a bigger picture of the evolution and ecology of these deep-sea creatures and their predators. University of Michigan professor of geological sciences Tomasz Baumiller will show the videos and discuss the research Oct.16 at a meeting of the Geological Society of Am...

Creeping crinoids! Sea lilies crawl to escape predators, new video shows

Student scientists create living bacterial photographs

...: It makes me sad when an article that should have picture doesn't ... at least I found the webpage of the student's group in the iGEM competition , check it out! Some pictures of the concept they'll use for their bacterial 'camera'. Using Petri dishes full of genetically engineered E. coli instead of pho...

The earliest animals had human-like genes

...ry similar to human genes. That's a much different picture than we've seen from the quickly-evolving species that have been studied so far." Raible is member of both Arendt's group and a second EMBL lab, that of Peer Bork, whose specialty is analyzing genomes by computer. "Human genes are typically more com...

Brains response to visual stimuli helps us to focus on what we should see, rather than all there is to see

...e, he explained. This new study is filling in the picture of how the brain is organized into "smart" efficient networks, and researchers hope that details of this complex design might, one day, uncover the roots of such neurological diseases as schizophrenia. "We know already that schizophrenia is a proble...

Researchers find gland that tells fruit flies when to stop growing

...essment, she said, and it provides a more complete picture of how an organism's growth is controlled. Mirth ... the new research clarifies the second part of the picture ?how an organism knows that growth should stop. "There has to be a way for an animal to assess its ...

New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia

...usands of years," Horvat said. "It's really a neat picture of what evolution and natural selection can do." Although it's hard to predict, the work may have implications for people designing enzymes later on, he said. Using enzymes in reactions can greatly reduce the cost of a lot of chemical processes. Fi...

A bug's life: Exceptional genomic stability yet rapid protein evolution in a carpenter ant mutualist

...rium and by extension, to its host. "Overall, the picture emerging is one of genome deterioration, with the loss of many gene functions, and extreme genome stability," says Wernegreen. "This genomic stability may prevent the reacquisition of those lost functions or the evolution of new ones. In addition, ra...

Restaurant seafood prices since 1850s help plot marine harvests through history

...e historical component of the Census is creating a picture of what lived in the oceans before fishing became important, and how these populations have changed since fishing loomed large ?a time 50 years ago in some areas, 500 in others, and 1,000 or more in a few," he says. "The history of marine animal pop...

Scientists discover new way to look at how molecules twist and turn on water

...is Hore, Daniel Beaman and Daniel Parks provides a picture of how these surfactant molecules orient at an aqueous surface. Theirs are the first studies to determine the detailed orientation of simple soap head groups at the water surface, using a unique combination of laser-based experiments and computer mo...
