It's been more than three years since the record for longest python ever caught in Florida was set. Could there be longer ...

Scientists have made mice with a remarkable amount of room for human brain tissue to grow. By genetically engineering animals lacking part of their brain, researchers created a living model in which ...

Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring ...

Megan covers the intersection of science and society. How is biomedical research funded? Who benefits? And how do new technologies reflect and shape our values? You can reach Megan on Signal at ...

A side view of a "xenocortical" mouse brain, with the grafted human tissue seen in green and red. S. Pașca Lab / Stanford University In a research lab in California, mice that look ordinary on the ...

Researchers hope to shed light on conditions such as schizophrenia, epilepsy, cerebral palsy, intellectual disability and rare forms of dementia Researchers have created mice with half-human brains in ...

Working from home or in the office each comes with its own set of distractions, but your mouse shouldn’t be one of them. A silent mouse lets you click, scroll, and work without the constant tapping ...

Scientists reconstructed videos from the brain activity of mice, producing 10-second clips based only on signals from neurons in the visual cortex. The breakthrough could help reveal how the brain ...

Researchers have developed a new way to install millions of human brain cells into mice, as a way of creating better scientific models for studying neurodegenerative disease. Using genetic tools, the ...

Semaglutide produced a striking result when given late in life to older mice: the treated animals lived longer and improved on several health markers, surpassing the outcome achieved through calorie ...

The animals may help reveal the causes of brain disease in people and point the way to treatments. But researchers already are calling for new ethical guidelines. The animals may help reveal the ...

Neuroscientists in the US have successfully adapted mice to have functioning human cells inside their own brains. The researchers hope that potential treatments for psychiatric and neurodevelopmental ...
