Phys.org / Martian volcanoes could be hiding massive glaciers under a blanket of ash

When we think of ice on Mars, we typically think of the poles, where we can see it visibly through probes and even ground-based telescopes. But the poles are hard to access, and even more so given the restrictions on exploration ...

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 / 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 / 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 / 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 / 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 / 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 ...

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 ...

Medical Xpress / 'Sensory checkpoint' in adult brain keeps remodeling itself long after adolescence, scientists find

The dominant theory in neuroscience has been that the sensory processing circuits in our brain are finalized in early childhood and fixed afterward. A recently published study, however, overturned this widely believed theory, ...

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 / Using moon dirt with 3D printing to build future lunar colonies

Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers ...
