Phys.org / Canadian wildfire smoke cooled New York by 3°C and trapped air toxicants, researchers find
When smoke from Canadian wildfires turned New York City skies apocalyptically orange in June 2023, it delivered catastrophic air quality and an unexpected side effect: cooling the New York City region by about 3 degrees Celsius.
Phys.org / Tree rings and models paint a picture of past, present and future drought
As the climate warms, drought conditions are intensifying in many parts of the world. The effects of hydrological drought on water levels in rivers and other waterways are especially crucial to monitor because they can affect ...
Phys.org / Urban heat islands: A double-edged sword for city dwellers' survival
Cities having higher ambient temperatures than rural surroundings (known as the urban heat island effect) could offset some of the negative effects of increased heat-related mortality by reducing the number of deaths associated ...
Phys.org / Weather forecasting technique speeds up electrocatalyst degradation predictions
A NIMS research team has developed an approach capable of accurately and rapidly predicting the degradation behavior of electrocatalysts used in water electrolyzers by employing data assimilation—a method commonly employed ...
Phys.org / Scientists can tell healthy and cancerous cells apart by how they move
Researchers from Tokyo Metropolitan University have found that the motion of unlabeled cells can be used to tell whether they are cancerous or healthy. They observed malignant fibrosarcoma cells and healthy fibroblasts on ...
Phys.org / Rethinking neutron star mergers: Study explores the effects of magnetic fields on their oscillating frequencies
Neutron star mergers are collisions between neutron stars, the collapsed cores of what were once massive supergiant stars. These mergers are known to generate gravitational waves, energy-carrying waves propagating through ...
Phys.org / Saturday Citations: An exoplanetary biosignature; the diplomacy of body odor; personalities of bees
This week, the Curiosity rover found large carbon deposits on Mars, suggesting an ancient carbon cycle. Researchers exploring the domestication of cats believe they may have originally pounced out of Tunisia. And researchers ...
Phys.org / Red, pink or white, all roses were once yellow says genomic analysis
Red roses, the symbol of love, were likely yellow in the past, indicates a large genomic analysis by researchers from Beijing Forestry University, China. Roses of all colors, including white, red, pink, and peach, belong ...
Phys.org / Layered room-temperature altermagnet shows promise for advanced spintronics
Traditionally, magnetic materials have been divided into two main categories: ferromagnets and antiferromagnets. Over the past few years, however, physicists have uncovered the existence of altermagnets, a new type of magnetic ...
Phys.org / Astronomers confirm the existence of a lone black hole
A team of astronomers at the Space Telescope Science Institute, working with one colleague from the University of St Andrews' Center for Exoplanet Science and another from the European Southern Observatory, has confirmed ...
Phys.org / Reusable moss-based adsorbent can help clean up oil spills
Hidden within sphagnum moss, commonly known as peat moss, is an adsorbent material that can help us combat oil spills. A study by researchers from China presents a new bio-based oil adsorbent derived from sphagnum moss that ...
Phys.org / Indian astronomers investigate the behavior of X-ray binary SXP 138
Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), Indian astronomers have observed an X-ray binary system designated SXP 138. Results of the NuSTAR observations, published March 26 on thearXiv pre-print server, ...
