U of MN researchers turn cord blood into lung cells

...rst few years of life. Now the researchers will try to better characterize the cells, so that in the future, the cells could be used as a research tool to better understand lung development and disease. The cells may also be useful as a way to test potential new drugs. To differentiate the lung cel...

Virginia Tech's System X supercomputer provides super tool for simulation of cell division

...and Celsius readings for the same temperature, and try to deduce the formula for converting between the temperature scales." Previously, Tyson worked with simpler models whose parameters could be determined by trial and error, a process modelers call "parameter twiddling." But he and his coworker, Kat...

Protein averts cell suicide but might contribute to cancer

Anti-dandruff compound may help fight epilepsy

...n work better. So now we have a chance to actually try to fix the causes of epilepsy, rather than traditionally circumventing them. Plus, this study really shows that we don’t fully appreciate the biological roles of many familiar chemicals that surround us.? ...

Scientists unravel clue in cortisol production

...ulfilling their roles. "One of the best ways to try and figure out the function of a protein or a gene is to get rid of it or mutate it so that it's not acting normally. Then you compare it with one that is acting normally," said Sewer. In this study, they focused on a protein known as steriodogeni...

Cells use 'noise' to make cell-fate decisions

...entists examine genes and proteins individually to try to determine their functions within a cell. However, Dr. Süel said that's like examining each capacitor or switch in an electrical circuit in an attempt to understand the function of the electrical device in which the circuit is housed. "Our resea...

Tears reveal some of their deepest secrets to researchers

... "Other scientists used different techniques to try to determine the composition of meibum, but mass spectrometry is sensitive enough to detect individual lipid molecules, like oleamide," Nichols said. Oleamide was first identified as a lipid in the brain, where one of its roles is to induce sleep....

Stanford scientists make major breakthrough in regenerative medicine

... hearts, broken spines, and wounded muscles always try to repair themselves, but often the result is invalidism or disease. Even some tumors try to revert to normal, but are unsuccessful. If the genetic sequence described in the sea squirt appl...

Neural bottleneck found that thwarts multi-tasking

... However, we experience severe limitations when we try to do even two simple tasks at once, such as pressing a button when a visual stimulus appears and saying a word when a sound is presented. This is known as dual-task interference," Dux, a postdoctoral research associate in the Department of Psycholog...

Tiny clue reveals new path toward heart disease

The team, which includes researchers from several universities in the United States and the United Kingdom, reports its findings in the April 2007 issue of American Journal of Human Genetics. The research ...

Rewarding fat rats

...oncepts and technologies developed by engineers to try to understand what makes animals tick, certain computer scientists and engineers look to the natural world for inspiration and guidance as they build intelligent machines. Ongoing research has already produced some computer programs and robots that c...

Notorious cancer gene may work by destroying messenger

...izabeth Murray will use three cancer-cell lines to try to identify what messenger RNAs ?which will also tell them what proteins ?are targeted and destroyed by PMR1. “That will help tell us whether Src works through PMR1 to contribute to cancer,?Schoenberg says. Funding from the National Institute...

New research says winning a Nobel Prize adds nearly 2 years to your lifespan

...he researchers carried out their study in order to try to answer a long-standing question for economists and medical researchers as to whether social status alone can affect people's well being and lifespan. Although the existence of some kind of effect is known from studies of monkey packs, in humans it...

Scientists find potential 'off-switch' for HIV virus

...up and the infection returns, so it makes sense to try to keep the virus asleep if possible." HIV weakens the body's immune system by invading CD4+ T cells, which in essence serve as the metaphorical generals in the body's defense system against illness. When an HIV virus particle invades a T cell, mo...
