Pacific gray whales facing ‘catastrophic’ die-off as climate crisis hits food supply
Trump administration urged to relist a species in ‘very, very serious trouble’ under Endangered Species ActClimate change is driving a gray whale “catastrophic mortality event” in the Pacific Ocean as melting sea ice depletes food sources and the animals starve, environmental gro
Report shows declining gun homicides, record gun suicides in 2024
Report shows declining gun homicides, record gun suicides in 2024
Nearly 45,000 people in the U.S. died by gun violence in 2024—one person every 12 minutes, on average—and an all-time high of 27,593 died by firearm suicide, according to the latest annual firearm mortality report from the Johns Hopkins Center for Gun Violence Solutions at the Jo
Dark energy flips its sign, but the Hubble tension refuses to budge
For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the Supernova Cosmology Project, led by Saul Perlmutter, and the High-Z Supernova Search Team, led by Brian Schmidt and Adam Riess, discovered something strange:
This electric field trick boosted heat flow by nearly 300%
This electric field trick boosted heat flow by nearly 300%
Researchers discovered that electricity can dramatically reshape how heat flows through certain ceramic materials, increasing heat conduction by almost threefold in a preferred direction. The unexpected result could lead to much more efficient cooling technologies and energy-savi
Climate change leaves northern tree swallows more vulnerable those in the southern US
Climate change leaves northern tree swallows more vulnerable those in the southern US
Tree swallows in the northern U.S. and Canada face the greatest risk from climate change despite responding to temperature the same way as tree swallows in the southern U.S., according to a new study led by Cornell researchers that analyzed nearly 95,000 nests across five decades
First came the dead fish, then invasive plants. A year later and Lake Suchitlán’s pollutio
First came the dead fish, then invasive plants. A year later and Lake Suchitlán’s pollutio
Fishers on El Salvador’s largest lake are still looking for answers after the die-off, with no explanation provided by the governmentFrom the village of Copapayo, Noel Avalos recalls the morning they ran to the shore of Lake Suchitlán, El Salvador’s main hydroelectric reservoir,
Study reveals how gas bubbles shaped Kīlauea's 2018 lava flow
Study reveals how gas bubbles shaped Kīlauea's 2018 lava flow
The lava that buried entire neighborhoods during the 2018 Kīlauea eruption was composed of nearly 80% gas bubbles near its source. A recent study shows that those bubbles played a central role in controlling how fast and far the lava traveled and that lava flow models need to acc

Most UK media reports on June heatwave failed to mention climate crisis
Exclusive: Analysis of nearly 2,500 articles finds almost three-quarters made no reference to global heatingMost of the UK media stories about the record-breaking heatwave that struck in June failed to mention the climate crisis, analysis has found.Nearly 2,500 articles about the
A 37-year soil experiment revealed a hidden climate threat
A 37-year soil experiment revealed a hidden climate threat
The world's longest-running soil warming experiment has revealed an unexpected climate concern. After nearly four decades, researchers found that warming can cause microbes to break down stable soil carbon that scientists once believed was largely protected. That releases extra c
Record-smashing US heat wave surges from West to East
Record-smashing US heat wave surges from West to East
A record-smashing heat wave was spreading Tuesday from the West toward the East Coast, placing nearly 100 million Americans under heat alerts.
Astronomers just found four hidden white dwarf stars near Earth
Astronomers just found four hidden white dwarf stars near Earth
Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's ultraviolet observations finally revealed the long-hidden stellar remnants, including one just 25 light-years away that took nearly three decades to confirm. Th
