Phys.org / WaterPuzzle uses magnets to model water's hydrogen bonds for hands-on classroom exploration
Water is one of the most essential components of life, and many of its unique properties arise from interactions between its molecules. Hydrogen bonds influence water's physical properties, contribute to the formation of ...
Phys.org / Ancient charcoal remains provide clues about Neanderthal camp organization
Usually, people associate archaeological studies with bones, pottery and primitive tools, but archaeologists often find other clues about how ancient people lived hidden throughout a site. A new study, published in the Journal ...
Phys.org / Cosmic microwave background offers evidence of gas flowing in galaxy clusters
The cosmic microwave background (CMB) is a faint glow in the universe dating back to roughly 380,000 years after the Big Bang, long before stars or galaxies emerged. Detecting this light and mapping its fluctuations provide ...
Phys.org / Ultrathin carbon ribbons conduct electricity like metals in first successful synthesis
As modern electronic devices shrink, so do the metal electrical wires inside them. However, they start to run into serious problems the smaller they get. Conventional wires generate excessive heat and suffer a massive spike ...
Phys.org / New catalyst builds proton highways to tackle a long-standing hurdle in green ammonia synthesis
Over a century ago, the Haber-Bosch process, a two-step reaction for the synthesis of ammonia (NH₃), an irreplaceable chemical for the fertilizer industry, prevented the world from going into a serious food crisis. Today, ...
Phys.org / Grand Theft Astro: Stars' criminal histories could reshape estimates of their internal magnetic fields
Magnetic fields exist in many stars, including the sun. Yet they remain too poorly understood to be reliably included in stellar evolution models, limiting their accuracy. Now, a new study by researchers at the Institute ...
Phys.org / As ancient oceans warmed, carbon export and fish productivity surged
Ocean fish stocks have been increasingly exploited over time, and remote sensing shows they have declined in the open ocean over the last three decades, particularly in the tropics. But it's uncertain how fish populations ...
Phys.org / Smaller ants devote more of their resting energy budget to their brains
The energy required for brains of different sizes to function could play a role in how different species evolved over time. While the energetic costs of brains have long been deemed important in evolution, direct measurements ...
Phys.org / Experimental study on moths supports the molecular cookie cutter idea proposed for butterflies
Have you ever thought about reinventing yourself? According to a new study on moths conducted by Andrei Sourakov, collection coordinator of Lepidoptera at the Florida Museum of Natural History and affiliate associate professor ...
Phys.org / Electrical signals reveal hidden magnetic information in altermagnets for first time
Researchers have experimentally demonstrated, for the first time, that it is possible to obtain from an altermagnet a spin current that can transport magnetic information. This result is supported by the theoretical model ...
Phys.org / Rare 4.1-billion-year-old Martian meteorite reveals clues to planet's ancient past
Scientists at the University of New Mexico have played a key role in identifying a rare, 4.1-billion-year-old Martian meteorite that provides new evidence that the red planet may have once had a wetter, Earth-like environment.
Phys.org / What drives temperature preferences? Female mice have temperature sensors tuned to run warmer
Female mice like warmer spaces than males because of two types of tiny temperature sensors in their nerves which are tuned to switch on at higher temperatures, according to researchers at the Institute of Psychiatry, Psychology ...
