Researchers boost solar concentrator efficiency

A team of researchers at the University of California, Merced, has redesigned luminescent solar concentrators to be more efficient at sending sunlight to solar cells.

Nanoprobes hit targets in tumors, could lessen chemo side effects

(PhysOrg.com) -- Tiny nanoprobes have shown to be effective in delivering cancer drugs more directly to tumor cells - mitigating the damage to nearby healthy cells - and Purdue University research has shown that the nanoprobes ...

Mysterious source of ozone-depleting chemical baffles NASA

A chemical used in dry cleaning and fire extinguishers may have been phased out in recent years but NASA said Wednesday that carbon tetrachloride (CCl4) is still being spewed into the atmosphere from an unknown source.

How single-celled organisms navigate to oxygen

A team of researchers has discovered that tiny clusters of single-celled organisms that inhabit the world's oceans and lakes, are capable of navigating their way to oxygen. Writing in e-Life scientists at the University ...

Mathematicians ask: What's in a ripple?

When a fluid or a gas experiences a sudden disturbance, such as a change in pressure or elevation, it often gives rise to a phenomenon known as an undular bore, which consists of a series of rapid oscillations that propagate ...

Students design cars the get 1000 MPG+

(PhysOrg.com) -- When you think about the design team for an ultra-fuel efficient vehicle, on that can get more than one thousand miles per gallon of gas; you probably picture a professional design lab outfitted with the ...

Drought increases CO2 concentration in the air

ETH researchers have shown that during drier years, the concentration of carbon dioxide in the atmosphere rises faster because stressed ecosystems absorb less carbon. This global effect is so strong that it must be integrated ...
