New study in The Journal of Urology® finds that a high intake of fruits, vegetables, and whole grains might not be enough. Men who followed a Mediterranean diet, rich in fish, boiled potatoes, whole fruits, vegetables, legumes, and olive oil, and low consumption of juices had lower risk of aggressive prostate cancer (PC) than those who followed other dietary patterns like Prudent or Western diets.

Although PC is the most common type of cancer in men and can have a high mortality rate, evidence linking ...

Scientists have solved a cosmic mystery by finding evidence that supermassive black holes prevent stars forming in some smaller galaxies. These giant black holes are over a million times more massive than the sun and sit in the centre of galaxies sending out powerful winds that quench the star-making process...

Researchers Jan Kramers and Georgy Belyanin found mineral compounds unlike anything on Earth, or in known meteorites or comets, in these fragments from the Hypatia stone, which was picked up in south-west Egypt in the Libyan Desert Glass Field.

Analyses on a small pebble in south-west Egypt cast significant questions on a widely-held view about the primitive pre-solar dust cloud which our Sun, Earth and other planets were formed from. Researchers found exotic micro-mineral compounds in the ‘Hypatia’ stone that are not known to occur on Earth, elsewhere in our solar system, or in known meteorites or comets.

In 2013, researchers announced that a pebble found in south-west Egypt, was definitely not from Earth...

UV Sense, wearable technology that sticks to the finger nail, measures UV exposure and sends safety information to an app. Credit: Northwestern University

A Northwestern University professor, working in conjunction with the global beauty company L’Oréal, has developed the smallest wearable device in the world. The wafer-thin, feather-light sensor can fit on a fingernail and precisely measures a person’s exposure to UV light from the sun.

The device, as light as a raindrop and smaller in circumference than an M&M, is powered by the sun and contains the world’s most sophisticated and accurate UV dosimeter. It was unveiled Sunday, Jan. 7, at the 2018 Consumer Electronics Show in Las Vegas and will be called UV Sense...
