| These Toads Are Surviving a Deadly Fungus – Scientists May Finally Know Why |
|
|
2026-09-05 12:01:37 +00:00
 Earlier development of diverse antimicrobial peptides may help some toad populations survive devastating chytrid fungus outbreaks. A deadly fungus has devastated frog and toad populations around the world, yet some groups eventually begin to recover even while the pathogen remains. Researchers led by University College London (UCL), ZSL, and Imperial College London have now identified [...]

| These Brain Cells May Explain Why We Eventually Have To Sleep |
|
|
2026-09-05 10:44:32 +00:00
 The longer we stay awake, the more certain brain cells appear to turn up the pressure to sleep, eventually making rest nearly impossible to resist. Sleep drive is the biological pressure to rest that builds during waking hours, making it increasingly difficult to stay alert. After prolonged wakefulness, it typically produces longer, deeper recovery sleep, [...]

| Scientists Discover Hidden Cells That Help Lung Cancer Evade the Immune System |
|
|
2026-09-05 02:53:51 +00:00
 Newly identified CHL1 fibroblasts may help lung cancers escape immune attack by recruiting regulatory T cells around tumors. A previously unknown population of fibroblasts appears to help lung tumors hide from the immune system by drawing suppressive T cells to the edge of the cancer. Columbia University researchers found that these CHL1-expressing cells can create [...]

| Scientists Push Molecules on a Surface to the Ultimate Quantum Limit |
|
|
2026-09-04 21:48:20 +00:00
 An ultra-clean crystal surface allowed individual molecules to preserve quantum coherence at the fundamental Fourier limit. A molecule placed on a surface should be easier to probe and manipulate than one hidden inside a solid or suspended in vacuum. In practice, however, surface contamination creates an unstable, noisy environment that can quickly degrade the molecule’s [...]

| World’s First Heat-Powered Cooling System Turns Waste Heat Into Cold |
|
|
2026-09-04 20:23:01 +00:00
 Researchers have developed the world’s first heat-driven elastocaloric cooling system, using waste heat and solar energy to support sustainable cooling. A cooling system powered directly by heat rather than an electric motor has worked in laboratory tests, offering a possible way to turn waste heat or solar energy into cooling. The prototype, developed by researchers [...]

| Greenland Just Lost a Manhattan-Sized Slab of Ice |
|
|
2026-09-04 16:56:05 +00:00
 A Manhattan-sized ice island has broken free from Greenland’s Petermann Glacier, and scientists say even bigger breaks may be coming. Europe’s Copernicus Sentinel-1 mission has documented a major breakup at Petermann Glacier in northwest Greenland, where a 76 sq km portion of the glacier’s floating ice tongue separated on August 4, 2026. The loss is [...]

| Antarctica Gained a Record 695 Billion Tons of Ice in Just Two Years |
|
|
2026-09-04 15:41:59 +00:00
 A tropical warming event helped drive record snowfall and a temporary 695-billion-ton ice gain in East Antarctica without reversing long-term Antarctic ice loss. Between 2021 and 2023, the Antarctic Ice Sheet gained about 695 billion tons of mass, the largest increase recorded by the GRACE satellites. New research traces much of that unusual gain to [...]

| SpaceX Dragon Leak Delays NASA’s Next Astronaut Launch |
|
|
2026-09-04 13:32:27 +00:00
 A leak in SpaceX’s Dragon propulsion system has delayed NASA’s Crew-13 launch while engineers work to clear the spacecraft for flight. NASA and SpaceX are delaying the Crew-13 mission to the International Space Station after an oxidizer leak was found in the propulsion system of the Dragon spacecraft during routine prelaunch processing. The leak was [...]

| Don’t Miss: A Brilliant Venus and Glowing Harvest Moon Light Up the Sky |
|
|
2026-09-04 12:17:33 +00:00
 September offers several eye-catching skywatching opportunities, including a brilliant Venus, the September equinox, and a Harvest Moon rising near Saturn and Neptune. The Moon can also help observers locate Antares, the Teapot star pattern, and, under dark enough skies, the direction of the Milky Way’s center. September Skywatching Highlights September 14-20: Follow the Moon to [...]

| New Twist on the Einstein Problem Reveals Unexpected Physics |

2026-09-04 02:51:19 +00:00
 Optical structures based on the Smith hat produced unusual light patterns that reflected their lack of mirror symmetry and changed with light direction and polarization. The Smith hat first drew global attention in 2023 because a single tile could cover an entire surface without ever creating a repeating pattern. Now, the same unusual geometry has [...]

| Scientists Just Challenged a Century-Old Theory of How Crystals Form |
|
|
2026-09-04 02:16:27 +00:00
 3D atomic imaging of advanced materials provides new insights into transitions such as liquids freezing into solids. For nearly a century, scientists have relied on classical nucleation theory to explain how phase transitions such as freezing and condensation get started. The theory describes how small, ordered regions called nuclei emerge within disordered matter, and a [...]

| Researchers Reveal the Hidden High Cost of “Free-To-Play” Video Games |
|
|
2026-09-04 01:41:01 +00:00
 A game may be free to download, but for a small group of players, the spending can become anything but small. Video games are a major source of entertainment for teenagers and adults, and many of the most popular titles now use a “free-to-play” business model. Players can begin without paying (‘free-to-play’ games), but they [...]
