The universe may be hiding conscious minds stranger than we can imagine
What if consciousness isn’t limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on E…
Scientists discover ancient brain cells that help block distractions
Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in mic…
Scientists discover hidden “footprints of death” that may help viruses spread
Scientists have uncovered a surprising new twist in what happens when cells die. As dying cells break apart, they leave behind tiny “footprints of death” packed with newly discovered particles that help guide the immune system to clean up the remains. …
Why South Africa’s leopards shrank to half their normal size
A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also…
Early humans were bringing fire into caves 1.8 million years ago
A new study suggests early humans were using fire in South Africa’s Wonderwerk Cave as far back as 1.79 million years ago. Researchers found burned bones deep inside the cave, where natural wildfires could not have reached, indicating that fire was lik…
New superconducting X-ray detector is up to 1,000 times more sensitive
A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The advance enables scientists to explore atomically thin mater…
Study challenges a common belief about vitamin D and sunlight
A study of nearly 300 people across northern Britain found that vitamin D levels often stay low all year in groups most at risk. Surprisingly, summer sunshine did not significantly boost vitamin D levels among older adults or people from minoritized et…
One tiny mutation may explain how bat viruses become human threats
Scientists found that one tiny genetic change can completely alter how a coronavirus behaves in different species. Comparing SARS-CoV-2 with a closely related bat-only virus, they showed that a single amino-acid difference affects whether the immune sy…
