Rats prefer to help their own kind; humans may be similarly wired

A decade after scientists discovered that lab rats will rescue a fellow rat in distress, but not a rat they consider an outsider, new research pinpoints the brain regions that drive rats to prioritize their nearest and dearest in times of crisis. It also suggests humans may share the same neural bias.

Galactic gamma ray bursts predicted last year show up right on schedule

Astronomers see many periodic emissions from space, typically caused by rotation of stars and often very regular. Astrophysicists noticed a unique periodicity in the soft gamma ray emissions from a magnetar located in our galaxy. The soft gamma repeater SGR1935+2154 appears to emit bursts only within regularly spaced windows, and is inactive in between. Based on their analysis, they predicted a...

Spectral-volumetric compressed ultrafast photography simultaneously captures 5D data in a single snapshot

Information-rich optical imaging can provide multidimensional information to enable observation and analysis of a detected target, contributing insights into mysterious and unknown worlds. With its ability to capture dynamic scenes on picosecond—and even femtosecond—timescales, ultrafast multidimensional optical imaging has important applications in the detection of the ultrafast phenomena in...

Developing lactose-free milk with graphene oxide based nano filtration membranes

Over the past years, graphene oxide membranes have been mainly studied for water desalination and dye separation. However, membranes have a wide range of applications, such as within the food industry. A research group led by Aaron Morelos-Gomez of Shinshu University's Global Aqua Innovation Center investigated the application of graphene oxide membranes for milk, which typically creates dense...
