Phys.org / 'Self-blinking dyes' simplify nanoscale imaging without sacrificing precision
Nanobodies are extremely small antibody fragments that bind to specific molecules. When nanobodies are labeled with dyes, they can be used as probes to enhance super-resolution microscopy. However, conventional blinking dyes ...
Phys.org / Extreme drought and heat from the last El Niño signal a 'new normal' for tropical forests
During the 2023–2024 El Niño, about 75% of the world's tropical forest areas experienced at least six months of unprecedented simultaneous drought and heat. According to a study published in Earth's Future, this scenario ...
Phys.org / Use of natural gas or propane in commercial kitchens exposes workers to air pollution and dangerous heat
Restaurant workers in commercial kitchens with gas and propane appliances can face heat and air pollution at levels above health-based guidelines, according to a new study by researchers from PSE Healthy Energy, the Stanford ...
Phys.org / Deep-sea clams adjust bacterial partnerships to cope with dwindling chemical energy
A research team led by professor Qian Peiyuan, chair professor in the Department of Ocean Science at The Hong Kong University of Science and Technology (HKUST), in collaboration with international partners, has made progress ...
Phys.org / Tortoise beetles use pigmentation protein to shield bacteria that help digest plants
More than 80 years ago, scientists discovered that differences in yellow pigmentation were critical to courtship success and failure for fruit flies. It was one of the first demonstrations linking genes to complex behavior, ...
Phys.org / Polymer coating tackles MXene's water stability challenge, boosting CO₂-to-methane production
A research team has developed a photocatalytic technology that improves the stability of MXene, an emerging material vulnerable to water, to efficiently convert carbon dioxide into methane.
Phys.org / Nuclear traces in whales' teeth help scientists reconstruct their life stories
New analysis of traces of radioactive fallout from nuclear weapons testing trapped in the teeth of stranded whales has helped scientists reconstruct their life stories.
Phys.org / Quantum simulations suggest lithium isotopes could affect biological reactions differently
While lithium has been used as a first-line treatment for the long-term management of bipolar disorder for more than 70 years, scientists still do not fully understand how it produces its therapeutic effects in the brain.In ...
Phys.org / Techno-optimistic scientists take fewer climate actions, study finds
Scientists who believe technology will largely solve the problems caused by climate change are 23% less likely to engage in civic climate action and 18% less likely to make high-impact lifestyle changes compared with scientists ...
Phys.org / Ancient spotted bat samples help researchers understand present-day population dynamics
Understanding changes in North American bat populations is critical to measuring the risk of extinction from emerging threats such as habitat loss, climate change, white-nose syndrome and other disturbances. A study published ...
Phys.org / A gamma-ray burst's engine stayed active for nearly a month, breaking the previous record
Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst occurred at a redshift of 0.8577, and the activity lasted about 27 days in the burst's own rest frame—around ...
Phys.org / Francis Halzen wins Nobel Prize in physics for work on mysterious ghost particles called neutrinos
Francis Halzen won the Nobel Prize in physics on Tuesday for his efforts to demystify a rare group of neutrinos, tiny cosmic particles that scientists believe offer clues to how the universe evolved.
