Phys.org / Rydberg atoms detect clear signals from a handheld radio
For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the incoming signals, Noah ...
Phys.org / InN thin films show transient Pauli blocking for broadband ultrafast optical switching
Recent decades have witnessed rapid advancements in high-intensity laser technology. The combination of laser irradiation and novel materials is opening exciting avenues for the design of functional materials and devices. ...
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 ...
Phys.org / Stress-testing the Cascadia Subduction Zone reveals variability that could impact how earthquakes spread
The Cascadia Subduction Zone is unusually quiet for a megathrust fault. Spanning more than 600 miles from Canada to California, the fault marks the convergence of the Juan de Fuca and North American plates. While other subduction ...
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 / 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 / How immune cells spot viral RNA fast: LGP2 helps MDA5 respond to short dsRNA
A study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science Tokyo. Using cryo-electron microscopy and high-speed atomic force microscopy, they found that LGP2 ...
Phys.org / Are climate models detecting monsoon changes a decade too early? 'Super-simulations' say yes
Changes in rainfall within global monsoon regions affect the livelihoods of billions. For years, climate models have suggested that the fingerprint of human-caused climate change on monsoons would become visible by a certain ...
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 ...
Medical Xpress / Why a 'spring in your step' happens: Dopamine may trigger a quick burst of movement vigor
New research by engineers at the University of Colorado Boulder aims to get to the bottom of why, as the saying goes, you get a "skip in your step" when you're happy.
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 ...
