Peer-reviewed journal that published the groundwater reconstruction results on June 3.
A Science Advances study of 210 tropical forest mammals finds that traits driving losses over 130,000 years now track with survival. Trait-based analogy is a shakier proxy than it looks.

A survey of fangs, spines, stingers and tusks finds durability and penetration trading off across a broad zone, not a single best shape. And the zone moves when you change the weighting.

Heidelberg researchers report that neodymium isotopes in a Rockall Plateau core track the volume of the Icelandic ice sheet across the past 230,000 years, not water masses alone.

An MPIK-led team turned an atomic gas into a time-dependent refractive element at FLASH, shaping an XUV pulse in space and in spectrum where solid optics simply absorb the light.

Bill Martin's group argues in Science Advances that the last universal common ancestor was vent chemistry, not a cell, and that bacteria and archaea became alive separately.

A Beijing Institute of Technology group stacked mercury telluride quantum dots on a two-colour OLED so that changes in infrared wavelength come out as red or cyan, not grey.

Europa Clipper's plasma instrument caught part of a coronal mass ejection that only an off-axis spacecraft could see, exposing a geometric gap in space-weather forecasting.

Direct measurements at the Beijing Meteorological Tower found trees supplied a tenth of VOC emissions but nearly half the reactivity that drives ozone, almost all of it isoprene.

A Science Advances paper says five ordinary human-associated microbes could stay alive in shadowed south-pole terrain. The expensive consequence is the baseline contamination survey it implies.

A Science Advances study dates the Jomon split from mainland East Eurasians to 27,000-19,000 years ago and reports fat-metabolism variants at frequencies far above living populations.

MIT's Horvitz lab reports that worms with broken cohesin build extra adrenergic neurons in place of GABA ones. The chromosome-structure complex is also a fate switch.

A Science Advances study finds capability tracks conformity: GPT-4 Turbo and Claude 3.5 Sonnet adopted their peers' choice between two meaningless options in groups of up to 1,000 agents.

Cores off northeastern Brazil date two intensifications of Atlantic overturning during a period when the circulation was mostly far weaker than today. One lasted about a century.

A machine-learning reconstruction finds severe, persistent groundwater losses across roughly 23% of Brazil, in the basins that supply much of the world's soy, sugarcane, coffee and oranges.
