2025-09-05 09:45:10 +00:00 JWST placed new limits on planets around Epsilon Eridani and demonstrated an improved technique for spotting faint signals. In science, a negative finding can be just as valuable as a positive one. Even the most advanced observatories are sometimes challenged by data artifacts, and this was the case with the James Webb Space Telescope’s recent […] Read more…
2025-09-05 09:20:16 +00:00 A team of astronomers spotted RBFLOAT, one of the brightest fast radio bursts ever seen, and traced it to a galaxy 130 million light-years away. Using CHIME’s new Outrigger array, researchers pinpointed its origin to a spiral arm near a star-forming region, strengthening the case for magnetars as the source of these mysterious blasts. One […] Read more…
2025-09-05 08:55:14 +00:00 A new study suggests that mysterious “dark dwarfs” could provide crucial insights into the true nature of dark matter. Celestial objects known as dark dwarfs might be concealed near the center of our galaxy, and scientists believe they could help unlock the secrets of one of the biggest mysteries in modern cosmology: dark matter. In […] Read more…
2025-09-05 04:23:23 +00:00 New research shows that self-medicating with cannabis can lead to higher paranoia, anxiety, and depression—especially for those with childhood trauma. Recreational users face fewer risks, but those coping with pain or distress tend to consume more THC and struggle more with mental health. Rising Cannabis Use and Mental Health Concerns A major study led by […] Read more…
2025-09-05 03:48:21 +00:00 Ultra-processed foods don’t just pack on pounds — they change the body in hidden ways. In a tightly controlled study, young men gained more fat mass on a processed diet even when calorie counts were the same as unprocessed meals. Researchers also found worrying spikes in plastic-derived chemicals, along with drops in testosterone and other […] Read more…
2025-09-05 01:11:07 +00:00 Experimental device harnesses quantum properties for efficient processing at room temperature. Engineers are working to design computers capable of handling a difficult class of tasks known as combinatorial optimization problems. These challenges are central to many everyday applications, including telecommunications planning, scheduling, and route optimization for travel. Current computing technologies face physical limits on how […] Read more…
2025-09-05 00:36:40 +00:00 Caltech experiments uncovered a stable double helix state in plasma flux ropes. The same principles explain cosmic structures such as the Double Helix Nebula. Research into the Sun’s outer atmosphere has led Caltech applied physics professor Paul Bellan and his former graduate student Yang Zhang (PhD ’24) to identify a previously unknown equilibrium state of […] Read more…
2025-09-04 14:41:46 +00:00 Scientists have uncovered a strange and messy new way that injured cells may heal themselves. In addition to known processes like programmed cell death and controlled recycling, researchers discovered that cells can suddenly “vomit” their internal machinery, purging themselves to reset into a stem cell-like state. This shortcut, called cathartocytosis, speeds up regeneration but leaves […] Read more…
2025-09-04 14:06:51 +00:00 Researchers have created a remarkable new approach to repairing spinal cord injuries by merging 3D printing, stem cells, and lab-grown tissues. They engineered tiny scaffolds that guide stem cells to form nerve fibers capable of bridging severed spinal cords. In experiments with rats, this method restored nerve connections and movement, offering new hope that one […] Read more…
2025-09-04 08:59:54 +00:00 A new study of human deep space communications identifies the regions of space where signals from extraterrestrial intelligence are most likely to be detected. If an extraterrestrial civilization were trying to detect human signals, where and when would they be most likely to find them? A recent study by researchers at Penn State and NASA’s […] Read more…
2025-09-04 08:24:51 +00:00 Research offers new insights into protecting Earth from harmful solar radiation. A team at the University of Minnesota Twin Cities has identified and studied a previously unknown type of plasma wave within Jupiter’s aurora. The discovery provides new insight into auroral activity on other planets and, in turn, deepens our understanding of how Earth’s magnetic […] Read more…
2025-09-04 03:14:50 +00:00 Scientists discovered Syriemys lelunensis, a 50-million-year-old fossil sea turtle from Syria. Near the city of Afrin in Syria, an international group of scientists, including members of the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen, has identified a previously unknown species of fossil sea turtle. Named Syriemys lelunensis under the direction […] Read more…
2025-09-04 02:39:46 +00:00 Weak magnetic fields once exposed humans to radiation. People adapted with shelter, clothing, and mineral protection. Our first meeting was a bit awkward. One of us is an archaeologist who studies how past peoples interacted with their environments. Two of us are geophysicists who investigate interactions between solar activity and Earth’s magnetic field. When we […] Read more…
