A star system just 16 light-years from Earth has puzzled astronomers for more than 170 years. Now, researchers have uncovered a surprising explanation for a signal that once suggested a giant planet was hiding there. Although the discovery rules out certain massive planets, it also helps narrow the search for smaller worlds that could potentially

Global warming has accelerated sharply over the past decade, with Earth heating up faster than at any point since modern temperature records began in 1880. A new study from the Potsdam Institute for Climate Impact Research (PIK) provides the first statistically significant evidence that the pace of global warming has increased since around 2015, even
NASA astronaut Anil Menon and CSA (Canadian Space Agency) astronaut Joshua Kutryk have completed a 7-hour, 11-minute spacewalk outside the International Space Station, marking another important step in a major upgrade to the orbiting laboratory’s power system. The astronauts finished their work at 3:08 p.m. EDT. During the spacewalk, Menon and Kutryk installed and deployed
Some childhood cancers may be far more dangerous than their initial risk classification suggests. Scientists have discovered that certain tumors considered less threatening can contain hidden populations of highly aggressive cancer cells, potentially explaining why some children experience devastating outcomes despite lacking the usual genetic warning signs. The discovery could change how doctors identify children
A surprising discovery made with NASA’s Hubble Space Telescope is challenging a leading explanation for how the early universe emerged from darkness. The findings suggest that powerful explosions from dying stars may have actually interfered with a process scientists once believed they helped drive. An international research team, including astronomers from the University of Michigan,
Why did crocodiles survive the asteroid impact that wiped out the dinosaurs 66 million years ago? New research suggests that their preference for warm environments may have given them a crucial advantage during one of Earth’s greatest mass extinctions. Scientists led by UCL (University College London) found that crocodiles and their ancient relatives spent much
What if time is not a fundamental part of the universe, but something that emerges from the changes taking place inside it? A physicist at the University of Birmingham has created a miniature universe in the laboratory that offers a surprising new way to investigate this possibility. Using thousands of atoms cooled to temperatures barely
A carefully structured combination of diet and exercise may offer a powerful way to put type 2 diabetes into remission in younger adults. In a new clinical trial, more than half of participants who followed an intensive lifestyle program achieved remission within just six months, compared with only 4% of those receiving standard care. The
A simple blood test could help identify people at increased risk of Alzheimer’s-related cognitive decline years before they experience any noticeable problems with memory or thinking. In a large international study, researchers found that older adults with very high levels of a particular blood biomarker faced a 38% chance of developing cognitive impairment within five
New findings from the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) suggest that scientists can recreate an extraordinary form of matter from the earliest moments of the universe using surprisingly small atomic collisions. By smashing oxygen nuclei together at nearly the speed of light, researchers have uncovered strong evidence of quark-gluon plasma (QGP),
Scientists at Johns Hopkins University have uncovered a surprising role for a vitamin A derivative in the development of human vision. Their research reveals how this molecule works alongside thyroid hormones to help form the part of the eye responsible for our sharpest sight, challenging a scientific explanation that has stood for roughly 30 years.
Scientists at Gladstone Institutes have discovered an unusual bacterial immune system that operates in almost the opposite way of previously known defenses. The surprising mechanism allows bacteria to activate a deadly self-destruct process when viruses attack, potentially offering new ideas for developing medical treatments and gene-editing technologies. The findings, published in Molecular Cell, reveal how
A small, circular hole in a 75,000-year-old Neanderthal shoulder blade may reveal one of the earliest known cases of deadly violence involving a wooden spear. The remarkable discovery, made in a cave in Iraqi Kurdistan, suggests that the individual was struck by a sharpened wooden weapon that passed through the chest, potentially in a deliberate
Scientists have uncovered an unexpected way certain metals can withstand extreme cold without becoming dangerously brittle. The discovery challenges long-standing ideas about how metals behave at extremely low temperatures and could help engineers develop tougher materials for some of the harshest environments imaginable. The findings, published October 14 in Nature, reveal a previously unknown microscopic
In the hills of north-west Morocco, overlooking the river that gives the site its name, research at Oued Beht is bringing to light a previously unknown chapter of the region’s past. The discovery of a substantial built structure suggests that, during the second millennium BC, communities in north-west Africa were actively shaping their environment. They
For nearly two decades, scientists have known that a common gut bacterium can produce a toxin that damages the colon and helps drive the formation of tumors. What they could not explain was how the toxin first attaches to intestinal cells and begins its attack. Now, researchers have uncovered that missing step, revealing a surprising
Oct. 30, 2026 – ESI Motion Inc. is proud to announce that it is supplying the Solar Array Drive Electronics (SADE) to Lockheed Martin for its work on the Space Development Agency’s Proliferated Warfighter Space Architecture (PWSA) programs. Under the agreement, ESI Motion’s SADE technology will support SDA as the PWSA is developed. Defending our
