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 ...

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...

TSRI chemists have developed a fascinating new theory for how life on Earth may have begun. Their experiments demonstrate that key chemical reactions that support life today could have been carried out with ingredients likely present on Earth 4 billion years ago. “This was a black box for us,” said Ramanarayanan Krishnamurthy, PhD, associate professor of chemistry at TSRI and senior author of the new study. “But if you focus on the chemistry, the questions of origins of life become less daunting.”

For the new study, Krishnamurthy and this team focused on the citric acid cycle...

Swallowable Sensors reveal mysteries of Human Gut Health

First human trials of gas-sensing capsule reveal potential new immune system. The new technology and discoveries offer a game-changer for the 1-in-5 people worldwide who will suffer from a gastrointestinal disorder in their lifetime. They could also lead to fewer invasive procedures like colonoscopies. The ingestible capsule (the size of a vitamin pill) detects and measures gut gases – H2, CO2 and O2 – in real time. This data can be sent to a mobile phone. Professor Kourosh Kalantar-zadeh, study lead and capsule co-inventor, said the trials showed that the human stomach uses an oxidiser to fight foreign bodies in the gut.

“We found that the stomach releases oxidising chemicals to break down and beat foreign compounds that are staying...
