Phys.org / A never-before-seen picture of eagle migrations
In 1899, scientists began tracking avian migration by placing a small ring with an identifier around birds' ankles. Researchers then had to recapture the birds elsewhere, leaving the journey between those points a mystery. ...
Phys.org / Nano-sandwich photocathode improves solar conversion of CO₂ into ethanol
Czech researchers at Charles University in Prague, led by Pavla Eliášová, have developed an advanced photocathode that helps convert the greenhouse gas carbon dioxide into pure ethanol using sunlight. The new technology solves ...
Phys.org / Airborne tuberculosis bacteria may mutate as they dry, revealing a target to curb drug resistance
Tuberculosis bacteria released into the air from infected individuals dry out to form infectious particles that are second only to measles in contagiousness. Weill Cornell Medicine investigators have discovered specific mechanisms ...
Phys.org / Takeaway cups may be releasing microplastics into your coffee
Single-use paper cups used for takeout coffee and other beverages release millions of microplastic particles when exposed to hot liquid, University of Queensland researchers have found.
Phys.org / How everyday household tasks impact relationships
The physical, cognitive and emotional loads of running a household should be recognized when examining the health of a couple's relationship, new research has found. A University of Queensland study examined the "tri-load" ...
Phys.org / Engineered bacteria offer a new way to accelerate rock weathering for carbon removal
Rock weathering, the breakdown and dissolving of rocks and minerals caused by their exposure to water, air and biological life, is a major regulator of Earth's atmospheric CO2 levels and climate. Throughout Earth's history, ...
Phys.org / Light reveals internal motion in electron crystals and can trigger their melting
Electrons, particles that carry a negative electric charge, typically move through materials. At low densities and temperatures, however, the electrical repulsion between them can overpower their tendency to move, prompting ...
Phys.org / Why some earthquakes caused by fracking come with warning signs
Fracking, the injection of high-pressure fluid to fracture rock and release oil or gas, can trigger earthquakes. While some sites generate small tremors beforehand that may provide an early warning, others produce few or ...
Phys.org / Bumblebees may self-medicate when exposed to fungal infections
There is an old saying that nature is the best medicine, and it turns out bumblebees might agree. A new study published in the journal Royal Society Open Science suggests that buff-tailed bumblebees (Bombus terrestris) may ...
Phys.org / Diamond clock combines two signals to cut temperature-driven drift
Despite all the advertisements for engagement rings and necklace gifts, natural diamonds are imperfect. Their carbon atoms are arranged in a cubic lattice, but they nonetheless contain several types of crystallographic defects ...
Phys.org / Scientists capture first molecular-level images of water reorganization during a reaction crucial for life
Some of nature's most important chemical reactions rely on the coupled movement of negatively and positively charged particles. These processes play central roles in photosynthesis, catalysis and biological energy conversion ...
Phys.org / Low temperature graphene growth opens a route to sustainable resource recycling
Graphene is an exceptionally useful material for creating batteries, catalysts and electronic devices. Yet producing graphene typically requires temperatures as high as 900°C (1,652°F), limiting energy efficiency and making ...
