Phys.org / Why nanoscale droplets don't coalesce and microscale droplets do

Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...

Phys.org / Airborne AI spots underwater munitions in shallow seas with high precision

A new airborne imaging approach can reliably detect unexploded weapons that lie in shallow coastal waters and remain an ongoing hazard to public safety, marine ecosystems and infrastructure worldwide. By combining advanced ...

Phys.org / 'Very dangerous' super typhoon nears US Pacific islands

Howling winds and lashing rain battered Guam and the Northern Marianas late Sunday, hours before the projected arrival of a "super typhoon" with force equivalent to a Category 5 hurricane over the U.S. Pacific territories.

Phys.org / Cosmic neutrino 'whispers' may surface in 5,000-day Super-Kamiokande signal

Neutrinos: They have no electric charge, pass through matter like a ghost and are so light they were initially thought to have zero mass. These are just some of the traits that make them so difficult to detect. Research on ...

Phys.org / Congo River freshwater rides 49-day Atlantic eddy to travel 200 kilometers offshore

The Congo River is the second-largest river in the world, releasing an average of 40,000 cubic meters of water per second into the Atlantic Ocean. This huge discharge rate creates a large plume of fresh water that fans out ...

Phys.org / Mummified dogs reveal Tiwanaku people buried companions beside homes long before they became status symbols

In the arid landscapes of southern Peru, around 1,100 years ago, someone carefully dug a small pit, laid down a woven mat and placed a young dog within as if sleeping, possibly wrapped in twine. Centuries later, the mummified ...

Phys.org / How proteins are inserted into cell membranes

Researchers from Heinrich Heine University Düsseldorf (HHU) have—in collaboration with colleagues from Ludwig Maximilian University (LMU) in Munich—analyzed the complex biochemical processes that bacteria use to insert proteins ...

Phys.org / Study demonstrates neurotransmitter communication in immune cells directly for the first time

Researchers at the University of Münster and Ruhr University Bochum have demonstrated for the first time in real time that the body's own defense cells use catecholamines—neurotransmitters such as dopamine and adrenaline—to ...

Tech Xplore / A COF-graphene hybrid opens new horizons for lithium-sulfur batteries

Lithium-sulfur (Li-S) batteries combine the abundance and affordability of sulfur with an energy storage capability far beyond that of current lithium-ion technologies. Practical deployment, however, has been slowed by a ...
