A shark-shaped, climate-shifting blob of warm water — as wide as the Pacific Ocean — is rising from the depths

And yes, that is indeed an illustration comparing a complex Earth system phenomenon to, well, a shark.

Peptide induces chirality evolution in a single gold nanoparticle  

Scientists have created a synthesis method to make optically active and chiral gold nanoparticles using amino acids and peptides for the first time. Many chemicals significant to life have mirror-imaged twins and such characteristics are conventionally called as chirality. This study describes how the chirality, typically observed in organic molecules, can be extended to three-dimensional metallic nanostructures. The research will be published in Nature and featured in its cover.

How to improve habitat conservation for migrating cranes

Habitat in their path through the northern Great Plains is being lost at an alarming rate, but identifying key spots for protection is a challenge. Now, researchers behind a new study have created a model of whooping crane habitat use with the potential to greatly improve the targeting of conservation efforts during their migration.

Study reveals new Antarctic process contributing to sea level rise and climate change  

A new study has revealed a previously undocumented process where melting glacial ice sheets change the ocean in a way that further accelerates the rate of ice melt and sea level rise. The research found that glacial meltwater makes the ocean's surface layer less salty and more buoyant, preventing deep mixing in winter and allowing warm water at depth to retain its heat and further melt glaciers from below.

Your Next Pilot Could Be Drone Software  

Would you get on a plane that didn't have a human pilot in the cockpit? Half of air travelers surveyed in 2017 said they would not, even if the ticket was cheaper. Modern pilots do such a good job that almost any air accident is big news, such as the Southwest engine disintegration on Tuesday. But stories of pilot drunkenness, rants, fights and distraction, however rare, are reminders that pilots are only human. Not every plane can be flown by a disaster-averting pilot, like Southwest C...

Modeling prosocial behavior increases helping in 16-month-olds  

Shortly after they turn 1, most babies begin to help others, whether by handing their mother an object out of her reach or giving a sibling a toy that has fallen. Researchers have long studied how this helping behavior develops, but why it develops has been examined less. A new study looked at the role of imitation to find that when 16-month-olds observe others' helping behavior, they're more likely to be helpful themselves.

Performing under pressure: Modeling oxidation in high-stress materials  

Each year, the effects of corroding materials sap more than $1 trillion from the global economy. As certain alloys are exposed to extreme stress and temperatures, an oxide film begins to form, causing the alloys to break down even more quickly. What precisely makes these conditions so conducive for corrosion, however, remains poorly understood, especially in microelectromechanical devices. Chinese researchers have started to chip away at why these materials corrode under mechanical stress.

Could statins ease deadly heart condition in rare neuromuscular disease?  

Decreased HDL and ApoA-l levels in the general population are associated with an increased risk of death from cardiomyopathy and heart failure. Researchers found the FA patients had serum ApoA-I levels lower than healthy control subjects. In preclinical studies using cell models that mimicked liver cells of patients with the rare disease Friedreich's ataxia (FA), a widely used cholesterol-lowering drug increased a precursor of HDL (high-density lipoprotein).
