Study begins to reveal clues to the cause and progression of sepsis

...ponents may yield better results. No one really knows why some people develop sepsis following an infection, said Scott Somers, Ph.D., who oversees sepsis grants at the National Institute of General Medical Sciences, which partially funded the work. This large study gives us a much clearer picture of se...

Handicapping tuberculosis may be the way to a better vaccine

.... Jacobs is optimistic about the research, but he knows there is still much that needs to be done. His team is already working to modify the strain to make it less virulent, putting them one step closer to replacing BCG....

Now that Chen knows that Arabidopsis has two genes involved in the transcription process, his research team wants to learn more about genes' possible roles in plant growth and development and where those tasks are performed. "The two genes each may have specialized fu...

Antibody retards growth and induces death in liver cancer cells

...er therapies have some modest benefits, but no one knows exactly how they work. We now have identified a pathway that appears to be overly active in more than 70 percent of the cancers we examined and, when targeted, leads to significant reduction in tumor cell proliferation and survival, said Dr. Monga. ...

But he has been encouraged by recent mouse studies in his lab, which have identified peptides that have shown protection against breast cancer. Lake is advancing these preliminary mouse st...

From the corner of the eye: Paying attention to attention

La Jolla, CA Every kid knows that moms have eyes in the back of their heads. We are adept at fixing our gaze on one object while independently directing attention to others. Salk Institute neurobiologists are beginning to tease apart the complex brain networks that enable humans...

Fossil DNA illuminates life

Several projects under Danish leadership have been drilling through the icecap on Greenland, and collected complet...

How pain distracts the brain

... to concentrate on work while suffering a headache knows that pain compellingly commands attentionwhich is how evolution helped ensure survival in a painful world. Now, researchers have pinpointed the brain region responsible for pains ability to affect cognitive processing. They have found that this pain-...

New method for reading DNA sheds light on basis of cell identity

... basis of cell identity the way that a liver cell knows that it is different from a skin cell has been rather vague, much like our understanding of heredity was prior to our knowledge of DNA, said Broad Institute director Eric Lander, a co-senior author of the study. The chromatin maps suggest that it ma...

MIT tool determines landslide risk in tropics

...slides, which occur frequently. Although everybody knows that, nobody has ever put a system in place to determine where this risk or hazard is higher," said Saldivar-Sali. In her thesis, Saldivar-Sali reports some 65 recorded landslides near Baguio City between 1991 and 2004. The area is becoming increas...

Helping chlorine-eating bacteria clean up toxic waste

Normal laboratory procedures haven't provided enough answers, because the bacteria are hard to grow in a petri dish, said Ruth Richardson, Cornell assistant ...

CU study reveals why starling females cheat

... fathered by other males," said Rubenstein. No one knows why superb starling females have lower rates of cheating, but Rubenstein said it suggests that there may be less conflict between the sexes than in other species. He is currently researching this issue. While it has long been known that males of ma...

Fat fish put obesity on the hook

Everyone knows that eating lean fish helps slim waistlines, but researchers from the Center for the Study of Weight Regulation and Associated Disorders at Oregon Health and Science University in Portland, OR, have found a new way fish can help eliminate obesity. In...

Research finds that circadian rhythms dominate all life functions

...ession studies. "Anyone who diets, for example, knows you shouldn't eat late, and now we are getting closer to understanding why exactly," said Ptitsyn, a researcher in the Bioinformatics Center at the College of Veterinary Medicine and Biomedical Sciences. The center is located in the Department of Mic...

Sporns and Honey suggest that a closer look at brain structure might provide a new perspective. Despite the huge amount of work being done by neuroscientists, relatively little is kn...

Dietary vitamin B6, B12 and folate, may decrease pancreatic cancer risk among lean people

... cases and 623 cancer-free control cases. No one knows why vitamin pills may not help ward off cancer, or why, in this study, it might have a deleterious effect, Dr. Schernhammer said, but some research in animals suggests that if there is a dormant tumor, folate and other similar vitamins may stimulate ...

Math that powers spam filters used to understand how brain learns to move our muscles

...of a brain is that each brain uses what it already knows to predict or believe that something new will happen, then uses that information to help make it so. We used the idea that prior experience and belief affect the probability of future outcomes, such as taking an alternate route to work on Friday be...

Jet lag: It's all about chemical reactions in cells

Now, new research by Cornell and Dartmouth researchers explains the biological mechanism behind how circadian clocks sense light through a process that transfers energy from light to chemical...

Sleepless for science: Flies show link between sleep, immune system in Stanford study
