Runners -- Let thirst be your guide

...volves recording a person’s weight digitally, then running on a treadmill for an hour and recording their ending weight after toweling off the body sweat. “Most people don’t know how much they really sweat while exercising, but this simple test can tell you approximately how much fluid losses you are generat...

Technique monitors thousands of molecules simultaneously

...s. Working with his students, Moeller started by running a well-known electrochemical Wacker oxidation reaction, which converts an olefin into a ketone using palladium(II) on selected electrodes on the chip. In order to do this, the palladium(II) reagent needed at a selected electrode was actually made at ...

Master regulatory gene of epithelial stem cells identified

...fferentiation," says McKeon. "The defect is simply running out of stem cells. When you run out of stem cells, you run out of those tissues as we have seen with the mice lacking the p63 gene." Having established that p63 was only important to the maintenance of stem cells, McKeon and his research team then...

Newborn neurons like to hang with the 'in' crowd

...ting, enriched environment—large cages filled with running wheels, colored tunnels and playmates—boost the number of neurons that manage to hook up with the existing network to 80 percent, reinforcing the observation that using one's brain cells is the best way to optimize brain function throughout one's lif...

Fat screen delivers plant-derived chemical with antidiabetic effects

...ld be candidates for novel insulin sensitizers. By running a technologically advanced screen of more than 500 bioactive compounds, the researchers found that harmine has such a positive effect on fat. The fat cells under examination were manipulated such that they literally lit up when fat-boosting PPARã bec...

Executable biology -- Computer science sheds light on animal development

...co before performing actual lab experiments. By running their model with a wide variety of gene mutation scenarios and comparing results with available laboratory data, they found that the fate of C. elegans vulval precursor cells depends upon the time-sequence of two cellular signaling pathways, as well ...

... substitute that "is specialized to keep the motor running smoothly even as it begins to run out of gas," says Gregg Semenza, M.D., Ph.D., a professor of pediatrics and director of the vascular biology program in the Institute for Cell Engineering at Hopkins. "This is one way that cells maintain energy produ...

Researchers identify ovarian cancer biomarkers

Racing neurons control whether we stop or go

...een light," winners are able to stop, and take off running again, more quickly than their comrades. New research reveals that a similar race goes on in our brains, with impulse control being the big winner. "The research provides new insights into how the brain controls movements, which helps explain the im...

HIV protein enlisted to help kill cancer cells

...grow very fast. So they are always on the verge of running out of natural ingredients like sugars, and mistakes are accumulating in their DNA," Hawkins says. "This results in signals telling cancer cells to die, but the cells don't quite have the permission they need to do it. Proteins like TAT-Bim can tip t...

... emissions of greenhouse gases, not because we are running out of fossil fuels, he added. ''There are reserves of coal for 200 years at least, and coal can be liquefied into fuel, but it produces an awful lot of CO2,'' he explained. Biofuels, on the other hand, are carbon-neutral sources of energy, Somerv...

The origin of the brain lies in a worm

...rtebrates have a CNS in the shape of a spinal cord running along their backs, insects and annelid worms like the earthworm have a rope-ladder-like chain of nerve cell clusters on their belly side. Other invertebrates on the other hand have their nerve cells distributed diffusely over their body. Yet, all the...

Experience affects new neuron survival in adult brain; study sheds light on learning, memory
