Metabolic compound could rewind fertility clock for women

Shifts in culture and lifestyle mean that more couples are waiting until later in life before trying to conceive. But there’s often a feeling of racing against the clock, as the quality and number of eggs declines in women as they approach middle age. … Continue reading Metabolic compound could rewind fertility clock for women→

New images reveal “golf ball asteroid” has seen its share of hits

Astronomers have taken the clearest-ever shots of asteroid Pallas, a large rock orbiting out beyond Mars. The new images revealed the surface of this tiny world to be heavily dotted with craters, to the point where it’s been dubbed the “golf ball aster… Continue reading New images reveal “golf ball asteroid” has seen its share of hits→

Solar-powered desalination systems could bring water to disaster zones

It’s one of life’s most frustrating ironies that Earth’s surface is over 70 percent water, but most of that is undrinkable. Desalination is an important technology that may help unlock more drinking water, and now two independent teams have developed n… Continue reading Solar-powered desalination systems could bring water to disaster zones→

New cancer vaccine molecules clump together to stay on target

Current cancer treatments take time, can harm healthy cells and have mixed results. Ideally, fighting cancer would be as simple as a vaccine, and scientists are taking steps towards that goal. Now, researchers at EPFL have developed a way to make vacci… Continue reading New cancer vaccine molecules clump together to stay on target→

Semi-transparent solar cells could make greenhouses self-sufficient

Greenhouses and solar panels both need to be placed in areas with a lot of sunlight – so why not combine the two? Semi-transparent solar cells could potentially be built into the glass roof panels of greenhouses, capturing light at wavelengths that pla… Continue reading Semi-transparent solar cells could make greenhouses self-sufficient→

Resurrected woolly mammoth genes illustrate genetic decline

Researchers have resurrected woolly mammoth genes in the lab. But this isn’t about bringing the extinct species back from the dead. These particular genes came from one of the last remaining mammoth populations, which are believed to have suffered gene… Continue reading Resurrected woolly mammoth genes illustrate genetic decline→

Problem protein could be new drug target for preventing heart attacks

Atherosclerosis is a disease where fatty plaques build up in the arteries, increasing a person’s risk of suffering a heart attack or stroke. But now, researchers at Oxford University have found a protein that appears to trigger this cascade of events, … Continue reading Problem protein could be new drug target for preventing heart attacks→

Interstellar isotopes found in Antarctica were forged from supernovae

In the pure white snow of Antarctica, scientists have found rare isotopes that don’t occur naturally on Earth. The isotope, known as iron-60, is usually forged in the crucible of supernova explosions, and the researchers believe it fell to Ea… Continue reading Interstellar isotopes found in Antarctica were forged from supernovae→

Food scientists cook up low-fat better butter made of mostly water

Often imitated but rarely matched, butter is one ingredient that it’s important to get right. People are picky about the consistency and creaminess of their butter, and healthier alternatives have trouble getting that right. Now, food scienti… Continue reading Food scientists cook up low-fat better butter made of mostly water→

Atomic experiment to detect dark energy fails to feel the force

The universe is generally believed to be expanding at an accelerating rate, thanks to a mysterious force dubbed dark energy. But how exactly does this force work? Researchers in the UK have conducted an experiment to test a hypothesis that th… Continue reading Atomic experiment to detect dark energy fails to feel the force→
