EPFL researchers have developed a chip-based laser that keeps a very stable frequency across its tested operating range, without needing active electronic control. Their research is published in the journal Nature Photonics.
Aurochs, the ancient ancestors of modern cattle, once roamed large parts of Europe, Asia and northern Africa. New research by an international team led by Lund University indicates that multiple factors contributed to their demise in northern Europe—one of the first areas where they became extinct.
Companies that use AI tools to write their earnings presentations are sounding increasingly alike, a new study finds.
Te Whare Wānanga o Waitaha | University of Canterbury (UC) School of Earth and Environment senior lecturer Dr. Robinson was part of an international research team investigating the Aug. 26 disaster, when a massive rock and ice avalanche in the Himalaya rapidly transformed into a devastating debris flood.
NASA’s Roman Space Telescope has demonstrated remarkable pointing stability and given its powerful planet-imaging coronagraph its first look at the cosmos. The telescope can already stay locked on a target with precision comparable to aiming a laser at a dime from about 150 miles away. Its coronagraph also captured stars in the Large Magellanic Cloud, confirming that the instrument can produce focused images.
Neutron stars, the extremely dense remains of massive stars that exploded at the end of their lives, are widely studied astrophysical objects. Some of these stars, known as pulsars, spin and send out beams of radio waves, making them appear to pulse as the beams sweep past Earth.
Attachment is the term psychologists use for the most significant relationships that hold people's lives together. But what makes an attachment relationship different from all others? According to the pioneering American–Canadian developmental psychologist Mary Ainsworth, it must meet the following six conditions.
Nearly 6 in 10 people with high blood pressure in a large England study had never been diagnosed or treated, and half of those already taking medication still had elevated readings. Researchers say a more proactive approach to finding and controlling hypertension could prevent thousands of heart attacks and strokes.
New modeling shows irrigating low-flammability vegetation substantially reduces the predicted spread and intensity of wildfires, which could give communities critical extra preparation time, according to a University of the Sunshine Coast study.
The mainstream view is that there are no particularly critical phases in the development of the immune system, but a study of hundreds of infants suggests otherwise
Mysterious 97-million-year-old magnetic fossils may be the oldest evidence of an animal using Earth’s magnetic field like a built-in GPS. Their sophisticated magnetic structure could have helped an unknown ocean creature navigate thousands of kilometers with surprising precision.
Hurricanes can displace renters even when their homes suffer no damage, according to new research led by Rowan University urban planner Qian He.
JWST has revealed that galaxies were spreading carbon, oxygen, and other heavy elements through space just 500 million years after the Big Bang. The surprising discovery suggests the young universe became chemically enriched much earlier than expected, potentially erasing traces of its very first stars.
Even as the Federal Reserve moves to raise interest rates for the first time in three years, many of the metrics that economists rely on to gauge the overall health of the economy—like jobs reports, the unemployment rate and the stock market—have looked relatively strong in recent months. Despite this, only about 24% of Americans rated the economy as "good" or "excellent" in a recent Pew Research Center survey.
Ultrashort electrical pulses allowed scientists to push superconductors closer than ever to the point where their electron pairs actually break apart. The method revealed hidden differences between superconducting materials and could open new ways to probe and control their quantum behavior.
As marketers increasingly turn to artificial intelligence (AI) tools to create content and improve the efficiency of their workflows, a new study by a Penn State researcher and collaborators proposes an approach to deploying AI-generated marketing content at scale while reducing the need for costly and time-consuming traditional testing.
Archaeologists have been arguing for more than a century about whether people first entered the American continents before, during or after the coldest peak of the last ice age, called the Last Glacial Maximum (LGM). Now, a new study of the available genetic evidence suggests the group that gave rise to today's Indigenous people migrated to the Americas no earlier than 21,000 years ago."The evidence points to the arrival of humans ancestral to contemporary Indigenous peoples likely near the end of the Last Glacial Maximum, but earlier migrations may also have occurred," study co-authors Bethany Potter, an archaeologist at the Kansas Geological Survey, and Savannah Hay, a biological anthropol...
A future NASA telescope could spot atmospheric phenomena on planets orbiting other stars
High-risk MDS stem cells appear to have an unexpected “energy addiction,” relying far more heavily than healthy blood-forming cells on a molecule called NAD. Disrupting this energy pathway selectively weakened the cancer-driving cells, revealing a potential new target for treatment.
An engineer has utilized AI to break a previously unsolved cipher used by Napoleon Bonaparte to send secret messages to his generals — enabling us to read a 217-year-old letter for the first time. The announcement has historians excited about AI's potential to become a modern-day "Rosetta Stone" for translating coded historical messages. Carter Church, an AI engineer at cybersecurity firm Sentinel One, laid out the findings in a post on X on Wednesday (Sept. 30), explaining how he gave OpenAI's new model GPT-6 Astra one prompt and one image to crack the centuries-old code. Six hours later, the task was complete."I didn't believe it at first," Church told Live Science in a message. "Everyone ...
An international team has reconstructed the face of a man who lived in what's now Ecuador more than 3,000 years ago and whose skull featured in one of history's great anthropological debates.The facial reconstruction is based on the Punin-2 skull, which a farmer discovered in a ravine near the town of Punín in the Chimborazo region of Ecuador's central Andes in the 1970s.A similar skull, Punin-1, had been found in the same ravine in 1923 during an expedition led by the American Museum of Natural History. Some scientists at that time suggested its physical features were archaic, especially its prominent brow. As a result, scientists proposed in 1925 that the first Punin skull was evidence of ...
