Scientists may have solved a 66-million-year-old mystery: how crocodiles survived the asteroid that wiped out the dinosaurs. A sweeping analysis of fossils and ancient climates suggests that their preference for warm environments placed them in tropical…
- ScienceDaily — Top news · ScienceA computer scientist breaks through a limit that stood since 1996
A computer scientist has achieved a breakthrough in a nearly 25-year-old problem involving how computers calculate distances across enormous networks. The new algorithm delivers more reliable estimates for closely connected points without sacrificing speed…
- ScienceDaily — Top news · ScienceHubble reveals a stunning twist in how the universe emerged from darkness
A surprising discovery by astronomers using the Hubble Space Telescope is challenging a leading explanation for how the early universe emerged from a dense fog of hydrogen roughly 13 billion years ago. Scientists once believed powerful winds from exploding…
- ScienceDaily — Top news · ScienceScientists reveal a hidden snakebite crisis killing up to 513,000 people a year
A startling new study suggests that venomous snakebites are killing far more people worldwide than official statistics indicate, with an estimated 274,000 to 513,000 deaths every year. Researchers found that as many as 7 million people could suffer snake…
- ScienceDaily — Top news · ScienceWhy some “lower-risk” childhood cancers turn deadly
Scientists have uncovered hidden aggressive cancer cells in children whose tumors were previously considered lower risk, revealing why some cases of rhabdomyosarcoma become unexpectedly deadly. The discovery could help doctors identify dangerous tumors…
- ScienceDaily — Top news · ScienceAstronauts just gave the International Space Station a powerful upgrade
Two astronauts completed a 7-hour, 11-minute spacewalk to install a new solar array on the International Space Station, bringing NASA one step closer to a major power upgrade. Once the final array is installed on November 5, the station will have up to 30%…
- ScienceDaily — Top news · ScienceScientists confirm global warming is accelerating faster than ever recorded
Earth is warming faster than ever recorded, with scientists detecting a major acceleration in global temperatures since around 2015. A new study reveals that the warming rate has surged to approximately 0.35°C per decade, nearly double the average pace…
- ScienceDaily — Top news · ScienceA mysterious star system just 16 light-years away may be hiding habitable planets
Astronomers have solved a 170-year-old planetary mystery in a nearby two-star system, discovering that a mysterious wobble was caused by stellar activity rather than a giant planet. Although Jupiter-sized worlds have been ruled out in key regions, smaller…
- ScienceDaily — Top news · ScienceScientists discover mysterious seahorse lookalikes that no one has ever seen alive
Scientists have discovered that three bizarre deep-sea fish that look exactly like seahorses actually belong to a separate evolutionary group, proving that nature created the same unusual body shape more than once. Nicknamed "sea muppets," these elusive…
