Phys.org / Cellular switch casts light on why humans are active in the day
Early mammalian ancestors were nocturnal, sleeping during the day while the dinosaurs dominated the land. However, some mammalian lineages, including human ancestors, independently transitioned to diurnality (active during ...
Phys.org / Most lab testing quietly inflates 2D transistor performance, research reveals
For nearly two decades, two-dimensional (2D) semiconductors have been studied as a complement or possible successor to silicon transistors, promising smaller, faster and more energy-efficient processors. To ease their production ...
Medical Xpress / Blood test predicts which bladder cancer patients may safely skip surgery
Circulating tumor DNA, or ctDNA, can predict metastatic risk in patients who receive bladder-sparing treatment for muscle-invasive bladder cancer, but it is not a good predictor of local recurrence within the bladder, according ...
Medical Xpress / Women under 25 with cervical lesions face higher risk of heart disease, study finds
Young women with a history of cervical lesions are at 20% higher risk of developing cardiovascular disease and more likely to die from it, compared to others their age without the condition. High-grade squamous intraepithelial ...
Phys.org / Female Daubenton's bats share scarce feeding grounds at the edge of their range, study finds
At newly colonized high-elevation sites in the central Italian Apennines, female Daubenton's bats take turns using the same hunting spots instead of feeding side by side. A study published by a research team from the University ...
Phys.org / From trash to climate tech: Rubber gloves find new life as carbon capturers
Every year, over 100 billion nitrile rubber gloves are produced. They are made from synthetic polymers—a material chemically related to plastic and derived from crude oil. The vast majority is used in the health care sector, ...
Phys.org / Rising carbon dioxide levels now detected in human blood
Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue. The findings are especially ...
Phys.org / The screech of peeling sticky tape conceals a rapid train of tiny shockwaves, ultrafast imaging shows
A new experiment has uncovered the mechanism responsible for the screeching sound made by peeling sticky tape. Using a combination of ultrafast imaging and synchronized acoustic recordings, Sigurdur Thoroddsen and colleagues ...
Phys.org / Why tropical cyclones' rainfall surges before landfall
A research team at The Hong Kong University of Science and Technology (HKUST) has analyzed 40 years of data covering about 1,500 tropical cyclones and discovered that average rain rates surge by more than 20% in the 60 hours ...
Phys.org / Promoters and enhancers: Tool catches gene-controlling DNA sequences doing each other's jobs
Researchers at the Weill Institute for Cell and Molecular Biology have uncovered new evidence that two major types of gene-controlling DNA sequences, promoters and enhancers, operate with a shared logic and often perform ...
Phys.org / Cooling without gases: Molecular design brings solid-state cooling closer to reality
Some solid materials can cool down or heat up when pressure is applied or released. This behavior enables cooling and heating technologies that do not rely on climate-damaging refrigerant gases. In practice, however, a major ...
Phys.org / Satellite data enable first global estimate of aerosol cloud cooling
Particles in the atmosphere, known as aerosols, cool the climate by acting as cloud condensation nuclei. The more cloud droplets form around these particles, the less sunlight penetrates a cloud. This cools the climate, although ...
