Loss of stem cells correlates with premature aging in animal study

...s that reside in each tissue type,” says Brown. We accelerated the aging process by wiping out a large fraction of these cells prematurely, in one fell swoop. Essentially, these mice start their young adulthood with two strikes against them in terms of long-term tissue maintenance, and so, they subsequently age ...

The authors postulate that these "rapid progressor" patients, predominantly smoking males, represent a distinct clinical phenotype compared with the usual "slow progressors" patients. "These findings high...

Biodiesel study targets cleaner air, cleaner engines

...d that the success of this project will lead to an accelerated adoption of biodiesel use in on-farm applications, not only in Ontario but across Canada. This will bring both environmental and economic benefits to Canadians, since biodiesel can be produced from local, renewable resources. Biodiesel is a renewabl...

World's largest flower evolved from family of much tinier blooms

...ooms, which now weigh up to 15 lbs., evolved at an accelerated pace. However, after increasing in size by a factor of roughly 79, the plant then reverted to a more sedate evolutionary pace. This evolutionary spurt is one of the most dramatic size changes ever reported among eukaryotes; if humans were to underg...

Anti-dandruff compound may help fight epilepsy

...els, the researchers could identify molecules that accelerated the recovery. One chemical that proved quite effective in improving channel recovery was zinc pyrithione (ZnPy), the active ingredient in many dandruff shampoos. Li explains that ZnPy has a shape that allows it to fit into the gate region of the ...

Smashing the time it takes to repair our bones

...es that would otherwise heal successfully could be accelerated with the use of these stimulants. Dr Hannay said normal fractures in young, healthy people took approximately six to eight weeks to heal. "It might be possible to significantly reduce the healing time. That would be the goal." Dr Hannay gra...

Weighty viruses

...ed to the gas phase, given an electric charge, and accelerated in an electric field. However, this process must leave the viruses intact. The researchers thus chose to use a very gentle method known as LIAD (laser-induced acoustic desorption). The virus particles are released from the sample by laser-induced sou...

Global changes alter the timing of plant growth, scientists say

Nanoparticle assembly enters the fast lane

The speed of nanoparticle assembly can be accelerated with the assistance of the molecule that carries life's genetic instructions, DNA, a team of researchers at the U.S. Department of Energy's Brookhaven National Laboratory recently found. Nanoparticles, particles with dimensions on the order of billio...

...t is likely to last two years. Those risks include accelerated bone loss, motion sickness, the inability to treat minor illnesses, an inadequate quantity of food and the possibility of "interpersonal tensions" between crew members. Risk 29 addresses the fact that Mars astronauts will be bombarded by high-energ...

Temperament linked to onset of cancer and early death in female rats

In an earlier study, University of Chicago researchers looked at the lifespan of male rats and found that the adventuresome males lived longer. Because the male rats died of a variety of diseases, they could not establish a re...
