Ultrafast technique unlocks design principles of quantum biology

Tweet

University of Chicago researchers have created a synthetic compound that mimics the complex quantum dynamics observed in photosynthesis and may enable fundamentally new routes to creating solar-energy technologies. Engineering quantum effects into synthetic light-harvesting devices is not only possible, but also easier than anyone expected, the researchers report in the April 18 edition of Science Express.

A Horsehead (Nebula) of a different color

Astronomers have used NASA's Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory's launch aboard the space shuttle Discovery on April 24, 1990.

A fresh take on the Horsehead Nebula

This year marks the 23rd year of observing for the Hubble Space Telescope. Alongside cutting-edge science, the orbiting observatory has produced countless stunning astronomical images. Some of the most striking and beautiful subjects of Hubble's images have been nebulae -- vast interstellar clouds of gas and dust.

Change diet, exercise habits at same time for best results, Stanford study says

Tweet

STANFORD, Calif. — Most people know that the way to stay healthy is to exercise and eat right, but millions of Americans struggle to meet those goals, or even decide which to change first.

Now, researchers at the Stanford University School of Medicine have discovered that focusing on changing exercise and diet at the same time gives a bigger boost than tackling them sequentially. They also found that focusing on changing diet first — an approach that many weight-loss programs advocate — may actually interfere with establishing a consistent exercise routine.

Sniffing out solutions for millions of Americans with smell loss

Tweet

BOSTON — Snot. It's not something most of us spend a lot of time thinking about, but, for a team of researchers in Washington, D.C., it's front and center.

Robert I. Henkin, founder of the Taste and Smell Clinic in is charmingly self-deprecating. He says with a chuckle that he's often called a "spit and snot doctor," but he knows all too well that for his patients – those who no longer can appreciate the fragrance of fresh-cut grass or the intricacies of an herb-infused sauce – such loss is no laughing matter.

Early cognitive behavioral therapy reduces risk of psychosis

Tweet

Young people seeking help who are at high risk of developing psychosis could significantly reduce their chances of going on to develop a full-blown psychotic illness by getting early access to cognitive behavioural therapy (CBT), new research shows.

Researchers from The University of Manchester found the risk of developing psychosis was more than halved for those receiving CBT at six, 12 and 18-24 months after treatment started.

Swedish study suggests reduced risk of dementia

Tweet

A new Swedish study published in the journal Neurology shows that the risk of developing dementia may have declined over the past 20 years, in direct contrast to what many previously assumed. The result is based on data from the SNAC-K, an ongoing study on aging and health that started in 1987.

Kepler discovers 5-planet system like Earth

Tweet

Researchers for the first time have identified Earth-sized planets within the habitable zone of a Sun-like star. Images of the star taken by Notre Dame astrophysicist Justin Crepp rule out alternative explanations of the data, confirming that five planets orbit Kepler 62, with two located in the habitable zone. The results were published in Science magazine today.
