Living view in animals shows how cells decide to make proteins

...e genetics to learn when and where in the animals' bodies alternative splicing decisions are made and, eventually, to learn what factors are critical in making these decisions," Garcia-Blanco said. "Given the importance of alternative splicing in health and disease," he added, "this anatomic mapping of s...

Cancer cells forming blood vessels send their copper to the edge

...ical to the spread of cancer and the copper in our bodies has been discovered by researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago, using a beamline at the Advanced Photon Source. Growing new blood vessels from existing ones ?a process called angioge...

Breathing easy: When it comes to oxygen, a bug's life is full of it

...ead, insects draw in oxygen through holes in their bodies known as spiracles and pump the oxygen through a system of increasingly tiny tubes (tracheae) that deliver oxygen directly to tissues and muscles. Insects typically have a pair of spiracles for each thoracic and abdominal segment. The same tubes t...

Major link in brain-obesity puzzle found

... obese, diabetic, and unable to stop eating. Their bodies lose the ability to sense the signals sent by leptin and insulin that tell the brain to slow down food intake and fat storage. For the new paper, they looked at not only normal mice and mice that didn’t have the SH2B1 gene, but also at mice that ...

Study of planarians offers insight into germ cell development

... nanos expression in planarians that had had their bodies and reproductive organs detached from their brains, the planarians regenerated new bodies, but with no reproductive cells. "This is the first time that nanos gene function has been studied in a non-traditional model organism," Newmark said. "This ...

Stanford scientists make major breakthrough in regenerative medicine

...science is to understand life so we can defend our bodies against injury, deformity, and disease. The ultimate medical treatment would be to change an abnormal organ or tissue back to its vibrant, normal state," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "This study is a landmark in ...

Bats prey on nocturnally migrating songbirds

.... In parallel, isotopic signatures of whole insect bodies and passerine muscular tissues were tracked throughout the year, serving as a control. The results elegantly showed that the bats ate only insects in summer, included some songbirds' flesh in their diet during spring, and depended a great deal on pas...

Bioluminescence at the service of a novel cerebral imaging technique

...y. Thus the activation by nicotine of pedunculate bodies (an important structure for learning and olfactory memory in the Drosophila) induces a secondary response which is delayed by about 10 to 15 minutes at the level of neuronal axonal projections. It is therefore probable that this new response (hither...

Protein discovery targets antibiotic-resistant bacteria

...g sensory pathways used by bacteria that enter our bodies and move from the stomach into the gastro-intestinal tract. “If we can block the sensory pathway, then the bacteria can’t adapt to that change in their environment, and won’t be able to infect,?says Dr. Martin. In North America, the people treated...

Wheat can fatally starve insect predators

... are called virulent, are capable of ridding their bodies of lectin and surviving. Avirulent larvae are unable to deactivate the lectin. However, the researchers believe that plants resistant to Hessian fly invasions may make several strains of lectins in response to virulent larvae, Williams said. Re...

Until recently, however, it was difficult to access some of these tissues for transplantation. Now, as a result of a new cooperative conceived by OHSU surgeons and administrators, Oregonians will ...

Paper challenges 1491 Amazonian population theories

...ple didn't stray very far from home, or from local bodies of water for several thousands of years. We looked at clusters of lakes and landscapes where people lived, and asked, did they leave their homesite to farm around other nearby lakes? No they didn't. These findings argue for a very localized use of Am...
