Phys.org / Atlantic weather pattern shaped southern Greenland's rain and snow for millennia, sediments reveal
In high-latitude coastal areas, Arctic amplification means that temperatures are rising faster than the global average. This combination of rising temperatures and changing precipitation patterns driven by the North Atlantic ...
Phys.org / Changes in DNA packaging help immune cells swell and burst
Immune cells are the elite athletes of the human body. While other cells stay in place, immune cells travel throughout our bodies, squeezing through small channels, stretching themselves, sampling the surfaces of other cells ...
Phys.org / New collar sensor could reveal how wildfire smoke affects animal health
When wildfire smoke fills the air, most people can go inside to avoid it. Wildlife does not have that option, and little is known about how animals living in remote areas respond to wildfires and smoke exposure.
Phys.org / Hearing tests reveal how sea lions and fur seals hear human-made noise
Curtin University and Taronga Conservation Society Australia researchers have conducted the first hearing tests on Australian sea lions and long-nosed fur seals, revealing what sounds these marine mammals can hear and helping ...
Phys.org / Losing plant diversity could reduce grassland CO₂ absorption 15% by 2050, model projects
A substantial loss of plant diversity could mean that grasslands worldwide, including meadows and pastures, would absorb around 15% less CO₂ through photosynthesis by midcentury compared with a scenario in which diversity ...
Phys.org / Seismic analysis reveals ancient traces of mantle flow beneath the Pacific's oldest plate
Seismic data captured by ocean-bottom instruments have revealed "fossilized" traces of mantle flow beneath the Pacific Ocean's oldest preserved piece of crust. The patterns of ancient flow traced in the uppermost mantle are ...
Phys.org / Scientists turn handheld car gadget into wildfire early-warning tool
Researchers at King's College London have converted an off-the-shelf product, usually used to determine whether car window tint is legal, into a scientific instrument that can measure leaf water content in seconds.
Phys.org / Plating matters: How sauce placement can make a dish appear healthier
Our experience of eating is shaped by the combined influence of vision, smell, touch and taste. The way food is presented can shape diners' expectations before they even taste it. Visual features, such as arrangement and ...
Phys.org / Almost 300,000 people now live in flood‑prone areas in the Nepalese Himalayas—new research
On Aug. 26, a rock and ice avalanche triggered a huge flood that swept through a steep valley in Nepal, leaving thousands dead and missing. It was an extreme example of a growing problem across the Himalayas. As glaciers ...
Phys.org / New electrode design breaks key barrier to greener ammonia production
A new approach to producing ammonia using renewable electricity has overcome a fundamental energy limitation of the technology, opening new possibilities for cleaner and potentially more cost-effective production of one of ...
Phys.org / Colombia's new bee checklist documents 738 species, including 246 newly recorded
A team led by a Penn State professor and doctoral student has compiled a checklist documenting the bee species in Colombia—the first of its kind for any country in the Western Hemisphere.
Phys.org / All-electrical imaging offers innovative alternative for tracking cell movement
Engineers from Brown University have developed a new way of imaging cell migration dynamics that are important in understanding critical processes like cancer metastasis, wound healing and immune response.
