Sulfur may be a new tool for finding alien life

Astronomers have identified sulfur as a potentially crucial indicator in narrowing the search for life on other planets. While sulfur itself is not necessarily an indication of habitability, significant concentrations of ...

What is quantum coherence?

We say a message is incoherent when we can't make it out, or when it doesn't make sense. A scribbled note, a drunken argument or a conversation taking place five tables down in a crowded cafe might all be incoherent. In general, ...

Breaking the pattern: How disorder toughens materials

Cut open a bone and you'll see a subtly disordered structure. Tiny beams, called trabeculae, connect to one another in irregular patterns, distributing stress and lending bones an impressive toughness. What if human-made ...

A blueprint for making cereal crops more resistant to fungal disease

Powdery mildew is a destructive fungal disease of barley that can result in crop losses of up to 40%. To protect themselves from powdery mildew, barley has evolved a series of immune receptors that each recognize matching, ...

Umbilical cord blood biomarkers may improve preterm infant care

Northwestern Medicine investigators have discovered how proteins expressed in umbilical cord blood at birth evolve during gestational development and could serve as biomarkers to inform new precision care strategies for infants ...

January smashes heat record, surprising scientists

Last month was the hottest January on record, blitzing the previous high and stunning climate scientists who expected cooler La Niña conditions to finally start quelling a long-running heat streak.

Study reveals opsin 3's role in mouse appetite control

Scientists discovered years ago that the hypothalamus—which helps to manage body temperature, hunger, sex drive, sleep and more—includes neurons that express the protein opsin 3 (OPN3). Far less clear, however, was what ...

Don't give up singing—research shows that we need it

Singing releases happy hormones, reduces stress hormones and strengthens muscles and bones. You improve your posture when standing and singing, whether in a choir, at school or at home in the shower. When you hear someone ...

Paving the way for seaweed as a future protein source

A sustainable food system for a growing global population requires a more diversified and climate-neutral protein production. After five years of research in the recently completed CirkAlg project, led by Chalmers University ...

Peer pressure can drive teen cyberbullying, study finds

Social pressure during adolescence, a stage in which children begin to yearn for acceptance and to feel part of a group, is a cause of cyberbullying, as a series of self-justifications lead those who engage in these attacks ...

New findings on the power of enzymes could reshape biochemistry

Using a series of more than 1,000 X-ray snapshots of the shapeshifting of enzymes in action, researchers at Stanford University have illuminated one of the great mysteries of life—how enzymes are able to speed up life-sustaining ...

How climate extremes fuel droughts and heavy rains

Millions of people are already experiencing the impacts of climate change in everyday life. A few tenths of a degree warmer and the life we know becomes increasingly at risk due to climate extremes such as heat waves, droughts, ...
