Airborne observations identify major source of US landfill methane emissions

Phys.org / 10h

A team has found via testing from airplanes that landfill work faces tend to be responsible for the biggest share of methane emissions in U.S. landfills. Their findings are published in the journal Environmental Science and Technology. The researchers are from Carbon Mapper, a California nonprofit dedicated to finding ways to reduce greenhouse gas emissions, Arizona State University and the U.S. E

Surveys show full scale of massive seabird die-off due to Pacific Ocean heat wave

Common murres decline due to heat

Murres, a common seabird, look a little like flying penguins. These stout, tuxedo-styled birds dive and swim in the ocean to eat small fish and then fly back to islands or coastal cliffs where they nest in large colonies. But their hardy physiques disguise how vulnerable these birds are to changing ocean conditions.

Paleoenvironmental study at Waterfall Bluff reveals leopard seal far from Antarctic waters

Phys.org / 12h

Waterfall Bluff Rock Shelter (WB) (Eastern Cape Province (ECP), South Africa) contains archaeological deposits demonstrating persistent and continuous human occupation spanning from Late Marine Isotope Stage 3 (~39ka–29ka) to the mid-Holocene (~8ka). It is at this site that the first leopard seal (Hydrurga leptonyx) specimen was recently recovered from a Pleistocene and Holocene zooarchaeological

Saturday Citations: M87* lashes out; a deep sleep discovery; proposal to build a digital cell

Phys.org / 12h

I love it when researchers observe an extra-weird particle, and this week, scientists reported the observation of a particle that only has mass when it's moving in a single direction. Good enough! An ancient DNA analysis suggests that Neanderthals and Homo sapiens interbred for about 7,000 years. And a new paper characterized the timeless awareness reported by people in states of deep meditation.
