Phys.org / The case for an antimatter Manhattan project
Chemical rockets have taken us to the moon and back, but traveling to the stars demands something more powerful. Space X's Starship can lift extraordinary masses to orbit and send payloads throughout the solar system using ...
Phys.org / Geodesic approach links quantum physics and gravitation
It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation is captured by Einstein's ...
Phys.org / Interstellar object covered in 'icy volcanoes' could rewrite our understanding of how comets formed
Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered in erupting icy, volcano-like structures called cryovolcanoes. Researchers also discovered that the ...
Phys.org / Probing the quantum nature of black holes through entropy
In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at extremely low temperatures, ...
Phys.org / Natural language found more complex than it strictly needs to be—and for good reason
Human languages are complex phenomena. Around 7,000 languages are spoken worldwide, some with only a handful of remaining speakers, while others, such as Chinese, English, Spanish and Hindi, are spoken by billions. Despite ...
Medical Xpress / FDA memo claims COVID vaccine tied to 10 child deaths
A confidential internal memo from the U.S. Food and Drug Administration (FDA) is creating new controversy around vaccine safety after an agency official said the COVID-19 vaccine may have played a role in the deaths of at ...
Phys.org / Rare high-resolution observations of a flare-prolific solar active region
Scientists have captured an exceptionally rare, high-resolution view of an active region that produced two powerful X-class solar flares—an achievement rarely possible from Earth. Using the GREGOR solar telescope in Tenerife, ...
Phys.org / Physicists create 'quantum wire' where mass and energy flow without friction or loss
In physical systems, transport takes many forms, such as electric current through a wire, heat through metal, or even water through a pipe. Each of these flows can be described by how easily the underlying quantity—charge, ...
Phys.org / Ancient dirty dishes reveal decades of questionable findings
Olive oil is the Swiss army knife of foodstuffs. It can dress salads, sauté vegetables, even grease squeaky hinges. And for archaeologists, its ubiquitous presence in excavated pottery offers a window into the economic, ...
Phys.org / Debris disk gallery shows tell-tale signs of asteroids and comets in distant solar systems
Observations with the instrument SPHERE at ESO's Very Large Telescope have produced an unprecedented gallery of "debris disks" in exoplanetary systems.
Phys.org / First evidence of lost-wax casting for silver in Bronze Age Western Europe uncovered
In a recent study, Dr. Linda Boutoille uncovered the first evidence of lost-wax casting of silver objects in Bronze Age Iberia and, to date, Western Europe. Published in the Oxford Journal of Archaeology, the study examines ...
Phys.org / 24,000 times more harmful to the climate than CO₂: Measurements reveal SF₆ gas emissions in Germany
Sulfur hexafluoride (SF6) is a chemically stable, colorless, odorless, and non-toxic gas. It is used all over the world, primarily as an insulating and protective gas in electrical switchgear within medium- and high-voltage ...
