Tiny worms reveal backup circuits that keep survival reflexes from failing
Tiny worms reveal backup circuits that keep survival reflexes from failing
A research team led by Professor Chaogu Zheng from the School of Biological Sciences at the University of Hong Kong (HKU), in collaboration with scientists from Princeton University and Columbia University, has discovered how sensory-motor circuits—nerve circuits that turn sensor
T. rex could become most expensive fossil ever - but it's a ​problem for scientists
T. rex could become most expensive fossil ever - but it's a ​problem for scientists
A 67 million-year-old Tyrannosaurus rex will go on sale in New York with a pre-sale value of $30m. O recorte ajuda a contextualizar a pauta dentro de Agro.
Yale scientists may have found how Parkinson's disease spreads through the brain
Yale scientists may have found how Parkinson's disease spreads through the brain
Yale scientists discovered two neuron surface proteins that appear to help spread the toxic protein linked to Parkinson’s disease. Blocking these proteins in mice dramatically reduced disease progression, offering a potential new target for future therapies.
Scientists finally solved the mystery of Earth's greatest mass extinction
Scientists finally solved the mystery of Earth's greatest mass extinction
Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms
Columbia scientists discover surprising link between serotonin and heart valve disease
Columbia scientists discover surprising link between serotonin and heart valve disease
Scientists have uncovered evidence that serotonin, the chemical best known for regulating mood, may also speed the progression of a common heart valve disease in some people. The research suggests that patients with degenerative mitral regurgitation who take SSRI antidepressants
Scientists discover how the brain rewires itself to truly multitask
Scientists discover how the brain rewires itself to truly multitask
Practice may do more than make perfect. Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain's "thinking" center, people became better
Oldest quasars ever discovered add to 'perplexing' space mystery
Oldest quasars ever discovered add to 'perplexing' space mystery
The Euclid space telescope has spotted the oldest quasars—the brightest objects in the universe—ever discovered, deepening a cosmic mystery that has been puzzling scientists.
Deep-sea life has a secret food source scientists never expected
Deep-sea life has a secret food source scientists never expected
Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and how carbon is stored on Earth.

Low-cost genome sequencing approach is powering genetics research on mental illness and ma
For researchers on the hunt for the genetic roots of disease, the cost of deep whole-genome sequencing makes it challenging to conduct large genetic studies involving thousands of participants, which are needed to reveal new genetic insights. So scientists at the Broad Institute

Scientists decipher how a psychedelic substance is created, then engineer a plant to produ
Long before scientists began studying them in the lab, mind-altering substances were already being gathered from plants, fungi and even animals for use in rituals, healing practices and mental health treatment. Researchers at the Weizmann Institute of Science have now managed to

The public isn't bored with economists, management scholars and sociologists but engaging
For years, we've been told a familiar story: Social scientists such as economists, management scholars and sociologists talk, and the public shrugs. The claim goes that people don't find our work interesting, that our expertise is fuzzy compared with "hard" sciences, and that jou
Spider-like creatures help uncover the surprising origins of fatherhood
Spider-like creatures help uncover the surprising origins of fatherhood
Citizen scientists have helped researchers solve a long-standing mystery about how parental care evolved in harvestmen. Using photos and observations from iNaturalist, scientists more than doubled the known cases of egg-guarding behavior and discovered that maternal and paternal
