Dogs can tell fear from sadness — and scientists saw it in their brains
Dogs may understand our emotions more deeply than scientists realized. Brain scans show that happy human faces activate regions in dogs linked to higher-level processing and reward, suggesting that smiles carry special emotional significance for them.
MIT neuroscientists discover the brain can reason without words
MIT neuroscientists have found striking evidence that language and logical reasoning are powered by separate systems in the brain. Even people with severe language impairments caused by stroke were able to solve challenging logic puzzles as well as peo…
“Cannot be explained” – New super steel stuns scientists
Scientists have created an unusually corrosion-resistant stainless steel that could replace costly titanium components used to produce green hydrogen. The breakthrough could reduce structural material costs by roughly 40 times and make seawater-based h…
Marine heatwaves are harming human health in surprising ways
Marine heatwaves are emerging as a threat not just to coral reefs and fisheries, but to human health and well-being. Researchers warn that unusually hot oceans can fuel stronger storms, trigger harmful algal blooms, reduce seafood supplies, disrupt liv…
King Harold may have lost England by backing the wrong pope
A forgotten fragment of a lost papal letter is offering a surprising new explanation for the Norman Conquest. England may have backed the wrong pope during a bitter religious power struggle, giving Pope Alexander II a political reason to support Willia…
Black holes older than the Big Bang could explain dark matter
Some black holes roaming the Universe today may actually be older than the Big Bang. A new cosmic “bounce” model suggests the Universe expanded from an earlier contracting phase, allowing ancient black holes to survive the transition as cosmic fossils….
150-million-year-old dinosaur footprints reveal something strange about its walk
A spectacular 150-million-year-old trail of more than 130 footprints captures a giant sauropod making a complete loop before continuing on its way. Its uneven stride hints that the long-necked dinosaur may have been walking with a limp.
NASA’s moon base is taking shape with 20+ lunar landings planned
NASA is assembling the foundations of a future Moon Base through a wave of robotic missions and powerful new commercial landers. More than 20 landings are planned through 2029, testing everything from precision landings and lunar communications to rove…
A simple blood test could detect multiple cancers and reveal where they started
UCLA researchers have created a blood test that can scan DNA signals for multiple cancers, liver diseases, and signs of organ damage—and even indicate where trouble may be developing. Early results suggest the inexpensive approach could bring medicine …
