Phys.org / A new global map uses a fleet of satellites to catch methane leaks from the energy sector
When it comes to global warming and greenhouse gases, methane is one of the bad guys. It's the second most important contributor to climate change after carbon dioxide. However, quantifying the exact amount being released ...
Phys.org / Rare brown dwarf discovered orbiting ancient star
Astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) and elsewhere report the discovery of a new brown dwarf about 60 times more massive than Jupiter. The newfound substellar object, designated TOI-7019 ...
Phys.org / A new family of barium-based crystals reveals rules for structural changes
The ultimate goal of materials scientists is to design and create materials with precise structures and tailored properties. Predictive technologies have advanced significantly with the rise of AI, yet the delicate nature ...
Phys.org / Scientists identify first non-coding gene that controls cell size
What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases. Until now, the genetic basis behind cell size has ...
Phys.org / Storms in the Southern Ocean absorb more atmospheric heat than climate models predict
Intense storms that sweep over the Southern Ocean enable the ocean to absorb more heat from the atmosphere. New research from the University of Gothenburg shows that today's climate models underestimate how storms mix the ...
Phys.org / Laser light and the quantum nature of gravity: Proposed experiment could measure graviton energy exchange
When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted their existence, and the ...
Phys.org / Category '6' tropical cyclone hot spots are growing
The oceanic conditions that churn up the very strongest of hurricanes and typhoons are heating up in the North Atlantic and Western Pacific, fueled by warm water that extends well below the surface. Human-caused climate change ...
Phys.org / Altermagnetism in RuO₂ thin films: A new magnetic material for the AI era
A research team has demonstrated that thin films of ruthenium dioxide (RuO₂) exhibit altermagnetism—the defining property of what is now recognized as the third fundamental class of magnetic materials.
Phys.org / Shaking magnets with ultrafast light pulses reveals surprising spin control
An international team of researchers led by Lancaster University has discovered a highly efficient mechanism for shaking magnets using very short light pulses, shorter than a trillionth of a second. Their research is published ...
Phys.org / Why do wombats have square poop?
Most people have a preferred way of communication—phone, text, email—but bare-nosed wombats have an unusual way of relaying information.
Phys.org / Living rocks in South Africa rapidly absorb carbon and grow in harsh conditions
South Africa is home to some of the oldest evidence of life on Earth, contained in rocky, often layered outcroppings called microbialites. Like coral reefs, these complex "living rocks" are built up by microbes absorbing ...
Phys.org / Webb observes pulsar-orbiting planet whose composition defies explanation
Scientists using NASA's James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our understanding of how it formed.
