Orca tail dolphins to hunt salmon—and may share the catch

Killer whales or orca (Orcinus orca) have been observed hunting with Pacific white-sided dolphins (Lagenorhynchus obliquidens) in the waters off British Columbia, Canada, and sharing fish scraps with them after making a kill, according to research published in Scientific Reports.

Swarm detects rare proton spike during solar storm

The European Space Agency's Swarm mission detected a large but temporary spike of high-energy protons at Earth's poles during a geomagnetic storm in November. It did this not with the scientific instruments for measuring Earth's magnetic field, but with its 'star tracker'

The solution to finding an atmosphere on TRAPPIST-1 e

The hunt is on for terrestrial exoplanets in habitable zones, and some of the most promising candidates were discovered almost a decade ago about 40 light-years from Earth. The TRAPPIST-1 system contains seven terrestrial planets similar to Earth, and four of them may be in the

Spillover from protected areas can help ecosystems survive

Spillovers from protected areas such as national parks and wildlife reserves can play a significant role in boosting biodiversity beyond their boundaries with potential benefits to people through ecosystem services such as climate mitigation, water retention and erosion control.

Paper mill waste could unlock cheaper clean energy

Scientists developed a high-performance hydrogen-production catalyst using lignin, a common waste product from paper and biorefinery processes. The nickel–iron oxide nanoparticles embedded in carbon fibers deliver fast kinetics, long-term durability, and low overpotential.

This 15 minute hepatitis C test could change everything

Northwestern scientists have created the fastest-ever hepatitis C diagnostic, delivering accurate results in only 15 minutes. The test uses the DASH rapid PCR system, originally developed for COVID, but adapted for whole blood samples. Independent testing showed 100% agreement
