Phys.org / Nanotube-based thermoelectrics open a new pathway to waste-heat energy conversion
Whenever someone asks ChatGPT a question, heat is generated somewhere in the server room—a data center. When an electric vehicle battery generates heat during operation, the heat must be managed continuously. Manufacturing ...
Phys.org / Arctic shipping alters cloud formation, study finds
A study led by the EPFL suggests that shipping emissions influence climate-relevant cloud formation and may affect regional climate processes far beyond the polar region.
Phys.org / 125-million-year-old fossil reveals 'pregnant' shellfish
An international team of scientists led by Dr. Graciela Delvene of the Geological and Mining Institute of Spain (CSIC) has uncovered the oldest known evidence of maternal care in shellfish, revealing that some freshwater ...
Phys.org / Astronomers map a magnetic 'skeleton' funneling gas into a stellar nursery
Stars form when vast clouds of cold gas in space collapse under their own gravity. But not all gas collapses, and not all clouds form stars equally efficiently. A longstanding puzzle in astrophysics is what controls this ...
Phys.org / Crashing insect populations lead to smaller tree swallows that reproduce less
Since the 1970s, the number of insects at Canada's Long Point Bird Observatory has dropped by more than 60%, according to a new study led by the University of Michigan. Because of this, today's birds are smaller and facing ...
Phys.org / Artificial light is keeping reef fish awake, and the effects may ripple across coral reefs
Artificial light spilling into coastal waters from cities, ports, roads and hotels is disrupting sleep in coral reef fish and is associated with changes in markers linked to brain health, according to a new study from Bar-Ilan ...
Phys.org / Four new chameleon species found on Mozambique's mountaintop 'sky islands'
Tropical rainforest patches perched on isolated granite mountains in northern Mozambique have yielded four new species of sylvan chameleons, according to a new study by Prof. Krystal A. Tolley and Dr. Werner Conradie, recently ...
Phys.org / How thousands of nature's longest sperm squeeze into a tiny fruit fly
When Jasmin Imran Alsous peered down her microscope lens, she expected to see chaos—a mishmash of tangled cells. She was viewing the inside of a male fruit fly's sperm storage organ, using a powerful microscope at the CCBScope ...
Phys.org / Third known interstellar visitor 3I/ATLAS may be billions of years older than the solar system, study finds
An interstellar comet that blazed past the sun last year could be nearly three times older than our solar system and is unlike anything ever seen before in our cosmic backyard, astronomers said Monday.
Phys.org / Women negotiate as effectively as men—but leave people happier
Men and women achieve similar economic outcomes in negotiations, but female negotiators foster stronger interpersonal relationships, which lead in turn to greater satisfaction with the result and a greater desire to negotiate ...
Phys.org / Seal pups and seabird chicks are suffering in extreme weather. How can we protect them?
Extreme weather is becoming the new normal, disrupting human communities across the globe.
Phys.org / The Caspian Sea has lost an area nearly the size of Sicily: Human activities are a major reason why
The Caspian Sea, the largest inland body of water on Earth, is shrinking. Not fluctuating, not entering another natural cycle, but shrinking.
