We summarize the week's scientific breakthroughs every Thursday.
- Animals
Watch an orca ram into a sunfish so hard it explodes
This strategy expands orcas’ already broad repertoire for dispatching different types of prey.
- Animals
This humpback whale hunting strategy has been out of sight — until now
Scientists documented humpback whales hunting together at the seafloor, coordinating their arrival to scoop up sand lances.
- Oceans
Deep-sea snails ride surface currents to reach distant hydrothermal vents
The finding shows how life spreads between isolated deep-sea vents — and how closely those ecosystems are tied to the sunlit ocean.
- Climate
A new map traces the sky’s water highways
Atmospheric rivers bring heavy rain and floods, but if they don’t come around, it could mean drought. A new global map reveals little-known pathways.
- Climate
Can geoengineering blunt El Niño’s fury?
Marine cloud brightening could cool part of the Pacific and weaken extreme El Niños, simulations suggest. But the approach could have risks.
- Climate
A robot swarm is on a mission to map Greenland’s perilous ice sheets
The ambitious expedition aims to fill data gaps about the glacier-sea boundary to predict when the world might tip into a catastrophic climate regime.
- Agriculture
Scientists say Beefalo are all beef, no -alo. Breeders disagree
A whole-genome analysis of Beefalo, a hybrid bison-cattle breed, suggests very few individuals have any bison DNA at all, a new study reports.
- Plants
Giant trees have tricks to work around drought
Samples collected at daring heights provide evidence for an untested theory of tree drought adaptation, while countering another.
- Animals
The animal behind most aggressive wildlife encounters may surprise you
Analysis of 3,000 incidents in Canada reveals which animal–human activity combos are especially risky. Of note: Elk and campgrounds are a bad mix.
- Microbes
New science on algae die-offs is too late for the Reflecting Pool
Iron and hydrogen peroxide trigger cell death via ferroptosis, which cascades killer molecules through the population, causing mass die-offs of algae.
- Earth
A tropical permafrost layer in Peru may be one of the world’s largest
Vast permafrost beneath the upper slopes of Peru’s tallest volcano could become a regional water source as glaciers in the Andes retreat.
- Earth
A 2011 earthquake bounced a seismic wave off Earth’s core, nudging Japan east
The wave's round trip to Earth's core set off a fault slip along Japan's plate boundaries, revealing a seismic hazard scientists hadn't recognized.
