Phys.org / How Jupiter may have redirected life's ingredients toward Earth 4.5 billion years ago
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution ...
Phys.org / Nitric oxide overload jams plant immune signals, researchers find
A new study from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment (CAFE) helps explain how plants can lose track of their own disease warnings.
Phys.org / Tanzania's iconic heritage sites face damage from state-backed tourism
Assessment of four heritage sites in Tanzania finds that all are under threat from the institutions meant to steward them, prioritizing income from tourism over the sites' preservation and refusing to engage with community ...
Phys.org / Interstellar object 3I/ATLAS reveals no technosignatures in seven-hour radio scan
Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory ...
Phys.org / Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks
Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel ...
Phys.org / Brightness 'gap' in ancient star cluster reveals missing red dwarfs
Scientists from the Space Telescope Science Institute (STScI) in Baltimore, Maryland, sought to study one stellar subject and ended up finding something even more exciting. The team's results published today in Astronomy ...
Phys.org / Nanomagnets control diamond qubits, pointing to more scalable quantum hardware
Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only if scientists can build and scale the hardware needed to run the machines. New research from Virginia ...
Phys.org / Overarming America: Game theory explores how fear and social pressure drive gun purchases
A Dartmouth College study is the first to map the interplay of personal choice and social networks that has led to the United States being one of the world's most heavily armed countries, with 120 firearms for every 100 people. ...
Phys.org / Why doesn't coffee taste like caffeine?
Though decaf fans might disagree, caffeine is a critical component of a cup of joe. This compound is incredibly bitter on its own, but regular coffee itself is not. A team reporting in the Journal of Agricultural and Food ...
Phys.org / Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing
For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate ...
Phys.org / We can predict space weather—what if we could also stop it?
The weather on Earth can get pretty messy sometimes. But in space, it can be wild, and the effects can be far-reaching. Solar flares, giant explosions on the sun, can send out streams of energy that block radio communications ...
Phys.org / Arctic river deltas face rising climate pressure while holding vast frozen carbon reserves
Many rivers flow into the Arctic Ocean north of the Arctic Circle—including the Lena in Siberia and the Mackenzie River in Canada. The deltas of these large and small rivers store large amounts of carbon, which is bound there ...
