This Australian meteor crater is oldest known, says study
“We found the world’s oldest asteroid strike in Western Australia. It might have triggered a global thaw.”

Editor’s note: This commentary is by John McClaughry, the vice president of the Ethan Allen Institute. Over the past 50 years I have seen a lot of bills introduced into the Vermont Legislature. Of all the bills over all those…
The hottest planet ever detected rips molecules apart and acts like a star
When we cast our gaze across the galaxy looking for planets that may host even the faintest signs of life, there are obvious non-candidates. Like the football-shaped planet that blasts heavy metal into the universe. Or the scorched marble that…
Lab turns trash into valuable graphene in a flash
Scientists are using high-energy pulses of electricity to turn any source of carbon into turbostratic graphene in an instant. The process promises environmental benefits by turning waste into valuable graphene that can then strengthen concrete and other composite materials.
Study connects marine heat wave with spike in whale entanglements
(University of California – Santa Cruz) Climate change is increasing the frequency and severity of marine heat waves — warm water anomalies that disrupt marine ecosystems — and this is creating new challenges for fisheries management and ocean conservation. A new study shows how the record-breaking marine heat wave of 2014 to 2016 caused changes along the US West Coast that led to an unprecedented spike in the numbers of whales that became entangled in fishing gear.
Children to bear the burden of negative health effects from climate change
(University of Texas Health Science Center at Houston) The grim effects that climate change will have on pediatric health outcomes was the focus of a ‘Viewpoint’ article published in the Journal of Clinical Investigation by Susan E. Pacheco, MD, an expert at The University of Texas Health Science Center at Houston (UTHealth).

Grandmother's sherry is making a comeback
When’s the last time you had a glass of sherry, that sweet Spanish wine with an old-fashioned reputation? For me, it was a complimentary goblet served nightly at a fusty bed-and-breakfast in Columbia, South Carolina — more than 10 years…
Blue-emitting diode demonstrates limitations and promise of perovskite semiconductors
(University of California – Berkeley) Halide perovskites have garnered attention because they’re highly efficient at capturing energy in solar cells and efficient emitters in diodes. But researchers failed at making perovskite LEDs that emit blue light. UC Berkeley chemists succeeeded, but X-ray studies of the LED’s structure show that it’s very sensitive to temperature, humidity and chemical environment. Hence environmental and chemical control is essential for stable operation. But these properties also allow for potentially broader use, such as sensors.
Black rock from Vesuvius eruption is actually someone's super-heated brain
A glassy black rock found inside the charred skull of an unfortunate victim of the Mount Vesuvius eruption has turned out to be a 2,000-year-old vitrified human brain, reports Phys.org. The remarkable finding is a testament to just how swift…
