Visiting space likely won’t cause permanent brain damage, says NASA study
Spending months in space has a major impact on astronauts’ brains, but three years back on Earth appears to reverse the change.
Scientists are growing animals in artificial wombs. Humans might be next.
Artificial wombs promise to give people a way to have biological children without putting their own health at risk.
The neurons that make us feel hangry
Researchers gave pinpointed a cluster of cells called AgRP neurons near the underside of the brain that may create “hangry” feelings.
Sound waves can trigger torpor-like state in mice and rats
Ultrasound stimulation triggers a torpor-like state in animals, suggesting a noninvasive way to put people into the state.
Gain-of-function research is more than just tweaking risky viruses
Gain-of-function experiments in the lab can help researchers get ahead of viruses naturally gaining the ability to infect people in the wild.
Chronic pain can be objectively measured using brain signals
Even though pain is universal and we know it happens in the brain, we've never before had a way to objectively measure its intensity.
Here’s how growing plants on the Moon could benefit Earth
Making plants grow on the Moon could be instrumental in helping gardens to grow greener on Earth in the face of climate change.
Did life evolve more than once? Researchers are closing in on an answer
Current scientific consensus is that life emerged from non-living molecules in a process called abiogenesis. But if life emerged once, why not more times?
Older people were 3x stronger at the end of this science-backed 8-week program
But what if you’re in your 60s, 70s, 80s or 90s? Is it “too late” to build muscle and fight sarcopenia? Here’s what the research says.
We’re analysing DNA from ancient and modern humans to create a “family tree of everyone”
Genetic genealogy not only helps us understand where we came from, but it could also be used for tracing the origin of genetic mutations.
