Just 75 mins of physical activity a week reduces risk of early death

The top two causes of death worldwide are cardiovascular disease and cancer. Both conditions are associated with well-known risk factors, including low levels of physical activity. A large, new meta-analysis has examined the link between physical activ… Continue reading Just 75 mins of physical activity a week reduces risk of early death

Fossils reveal largest-ever penguin was probably bigger than you

An artist's reconstruction of the two new penguin species: Kumimanu fordycei and Petradyptes stonehousei

Scientists have discovered the fossil remains of what may be the largest penguins that ever lived. The bones, found on a beach in New Zealand, belonged to a giant bird that was more than three times the size of the biggest living penguins today.

Brain-frequency primer accelerates learning and retention

The brain is a constant center of electrical activity, and when measured via electroencephalogram (EEG), certain patterns emerge, in the form of regularly oscillating brainwave activity. When you’re feeling calm and relaxed, or even meditative, your br… Continue reading Brain-frequency primer accelerates learning and retention

Horde of the rings: Tree study suggests Huns’ motivation for marauding

As long-living lifeforms, trees can provide scientists with a way to look back into the past, revealing everything from a reversal in Earth’s magnetic field 42,000 years ago to a time in 774 CE when the planet was bombarded by a massive radiation storm… Continue reading Horde of the rings: Tree study suggests Huns’ motivation for marauding

Study suggests hunters may have caused rhinos to evolve smaller horns

If certain animals posses a trait that decreases their chance of survival, then that the trait is less likely to be passed along to offspring. Such appears to be the case with rhinos hunted for their large horns, according to a recent analysis of photo… Continue reading Study suggests hunters may have caused rhinos to evolve smaller horns

“Cosmic magnet” recreated in lab as alternative to rare earths

Rare earth elements are a key part of electronic and mechanical devices, but they’re in short supply. Now, scientists have found a way to recreate a promising alternative – a “cosmic magnet” that normally takes millions of years to form in meteorites c… Continue reading “Cosmic magnet” recreated in lab as alternative to rare earths

New study adds compelling evidence for lake of liquid water on Mars

New evidence has emerged in the ongoing debate about whether or not there’s water on Mars. In a study led by the University of Cambridge, scientists examined the topology of Martian ice sheets and found signatures that match subglacial lakes here on Ea… Continue reading New study adds compelling evidence for lake of liquid water on Mars

Cambridge cancer breakthrough may prompt rethink of metastasis

Cancer’s ability to spread through the body is one of its most devastating tricks. Scientists at Cambridge have now identified a protein that plays a key role in metastasis, which not only hints at a new potential treatment but reveals for the first ti… Continue reading Cambridge cancer breakthrough may prompt rethink of metastasis

Study debunks “stoner” myth that cannabis users are lazy & unmotivated

For almost a century popular culture has been filled with images of lazy, unmotivated “stoners” who do little more with their lives than smoke cannabis, but a new study from a team of UK researchers is busting that long-held myth. Across a series of la… Continue reading Study debunks “stoner” myth that cannabis users are lazy & unmotivated

Floating artificial leaves produce fuels from water, air and sunlight

The leaf is one of nature’s most impressive little machines, able to convert sunlight, carbon dioxide and water into energy. Scientists at Cambridge have now created a type of artificial leaf that can float on water, tapping into sunlight above it and … Continue reading Floating artificial leaves produce fuels from water, air and sunlight
