Plain packaging may help tackle teen vaping

A new study found that plain packaging of vape pods reduces young people's interest in trying them, but does not affect adults' interest. Standardised packaging also failed to deter adults from perceiving vapes as harmful compared to cigarettes.

More than a reflex: How the spine shapes sex

The study found that a specific spinal circuit is involved in both ejaculation and arousal, and integrates sensory inputs to adjust its output based on the animal's internal state. The researchers also discovered that Gal⁺ neurons receive sensory input from the penis and can trigger ejaculation, but their effects are suppressed by brai...

Montana State alumnus discovers new, extinct crocodyliform in Montana

A 2023 MSU graduate's undergraduate research project uncovered a new, 95-million-year-old crocodyliform named Thikarisuchus xenodentes. This tiny creature lived on land, feasting on plants and insects, with unique teeth that shed light on ancient ecosystems and evolutionary patterns.

How a blood test can aid spinal cord injury recovery

A recent study by the University of Waterloo found that routine blood samples can provide early warnings for spinal cord injury patient outcomes. The research team used machine learning to analyze hospital data from over 2,600 patients and discovered patterns in common blood measurements that could forecast recovery and injury severity.

USTC deciphers temperature-governed processes of lithium-mars gas batteries

Researchers from USTC deciphered the temperature-governed processes of lithium-mars gas batteries, finding that temperature regulates a balance between two-electron and four-electron processes. Low temperatures cause interface passivation, while high temperatures stimulate decomposition efficiency through the generation of highly activ...
