New research suggests Einstein and Rosen’s famous “bridge” may actually reveal something even stranger: time itself could flow in two directions at once. Instead of connecting distant places in space, these bridges may connect mirror versions of time deep inside quantum physics, potentially solving the long-standing black hole information paradox and hinting that our universe existed before the Big Bang. Fri, 22 May 2026 09:09:27 EDT https://www.sciencedaily.com/releases/2026/05/260522023129.htm https://www.sciencedaily.com/releases/2026/05/260522023123.htm NASA’s Psyche spacecraft skimmed past Mars in a precision flyby that helped catapult it deeper into space toward its ultimate target: the bizarre metal-rich asteroid Psyche. During the encounter, it snapped detailed images of heavily cratered Martian terrain, including the striking double-ring Huygens crater.

Measurements from mine boreholes in Ontario show the gas can flow continuously for years, offering a potential new source of clean energy called “white hydrogen.” Researchers say this hidden resource could help power industries and remote communities while cutting carbon emissions and reducing dependence on fossil fuels. Wed, 20 May 2026 08:46:14 EDT https://www.sciencedaily.com/releases/2026/05/260519224317.htm https://www.sciencedaily.com/releases/2026/05/260519224314.htm Why did T. rex have such tiny arms? Scientists now think it’s because its giant head became the ultimate hunting tool. Across multiple dinosaur groups, stronger skulls and crushing jaws evolved alongside shrinking forelimbs, especially in predators hunting enormous prey. In other words, once the bite became deadly enough, the arms may have stopped mattering. Wed, 20 May 2026 00:29:06 EDT https://www.sciencedaily.com/releases/2026/05/260519224314.htm https://www.sciencedaily.com/releases/2026/05/260519224312.htm Women may be especially sensitive to the effects of common dementia risk factors, according to a new UC San Diego study of over 17,000 adults.

The specially engineered nanoparticles helped clear toxic amyloid proteins from the brain and repair the blood-brain barrier, which normally protects and regulates the brain’s environment. In one striking experiment, elderly mice treated with the therapy later behaved like healthy younger mice.

The glowing strand stretches 3 million light-years and links two galaxies from nearly 12 billion years ago. By observing this faint intergalactic gas directly for the first time in such detail, scientists gained new insight into how galaxies are fueled and formed.

By creating a new tool that temporarily boosts mitochondrial activity in the brain, scientists restored memory performance in mouse models of dementia. The discovery hints that energy failure inside neurons could happen before brain cells die, potentially offering a new target for future Alzheimer’s treatments.

The strongest evidence appeared in the prefrontal cortex, the region tied to emotional control and decision-making. Researchers say the discovery is the first clear chemical brain pattern linked to anxiety and could eventually lead to new nutrition-based treatments.

The find overturns the classic “ape-to-human” progression and paints human evolution as a crowded, branching tree with multiple species coexisting. Scientists dated the fossils using volcanic ash deposits and are now investigating what these ancient relatives ate and whether they competed for resources.

Using decades of geological data, researchers found that distant tectonic activity linked to the ancient ocean appears to match periods of rapid mountain formation. Surprisingly, climate and mantle processes played only a minor role. The discovery could reshape how scientists understand mountain building across the planet.

Researchers discovered that certain brain cells stay highly active even after a workout ends, and those lingering signals appear to help the body build endurance over time. In experiments with mice, blocking these brain cells prevented improvements in stamina, even when the animals still exercised normally.

Paleontologists uncovered the best-preserved stegosaur skull ever found in Europe, belonging to the iconic plated dinosaur Dacentrurus armatus, which roamed Earth around 150 million years ago. Because stegosaur skulls are extremely fragile and almost never survive intact, the fossil is helping researchers uncover previously unknown details about how these armored giants evolved.

Researchers now believe the fault contains hidden “brake zones” where seawater and unusual rock structures work together to stop quakes from becoming even larger. The discovery came from ultra-detailed seafloor recordings that captured how the fault behaves before and after major earthquakes.

Using advanced light-based brain stimulation in mice, researchers identified a serotonin-driven circuit linked directly to tinnitus-like behavior. The findings may explain why some people experience louder ringing in their ears while taking SSRIs. Fri, 15 May 2026 07:11:38 EDT https://www.sciencedaily.com/releases/2026/05/260515002155.htm
