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 ...
A newly discovered part of the brain is essential for successful embryo implantation in mice. It may help to explain why some pregnancies and IVF attempts fail
Mathematicians have a new bucket list of open questions to chase
How foraging can change the way we think about food and nature
Strength training may be one of the most powerful tools for staying independent as you age. Age related muscle loss, known as sarcopenia, can make everyday tasks harder while increasing the risk of falls, fractures, and loss of mobility. Research shows that resistance exercises such as squats, weights, resistance bands, and even body weight movements can preserve or rebuild strength, and surprisingly, even one session a week can produce meaningful benefits.
