Tyrannosaurs may be famous as fearsome apex predators, but new research reveals a more opportunistic—and slightly grim—side to their behavior。 Using high-resolution 3D scans, a researcher identified precise bite marks on a massive tyrannosaur foot bone, showing that a smaller tyrannosaur had fed on the remains of a much larger relative over 75 mill
In a striking glimpse into extreme physics, scientists have captured the split-second chaos that unfolds when powerful laser flashes blast matter into a superheated plasma。 By combining two cutting-edge lasers, researchers were able to track how copper atoms lose and regain electrons in trillionths of a second, creating and dissolving highly charge
Physicists are rethinking one of quantum mechanics’ biggest puzzles: how fuzzy possibilities become definite reality。 New research suggests that spontaneous “collapse” processes—possibly linked to gravity—could subtly blur time itself。 This wouldn’t affect clocks we use today, but it reveals a hidden limit to how precise time can ever be
Coffee doesn’t just energize—it actively reshapes the gut and mind。 Researchers found that both caffeinated and decaf coffee altered gut bacteria in ways linked to better mood and lower stress。 Decaf even improved learning and memory, while caffeine boosted focus and reduced anxiety
A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don’t exist under normal conditions。 By carefully “driving” materials with timed magnetic shifts, researchers created exotic quantum states that could be far more stable and resistant to errors—one of the biggest challeng
Researchers at Stanford have developed a compact optical amplifier that dramatically boosts light signals using very little power。 By recycling energy inside a looping resonator, the device achieves strong amplification with minimal noise and wide bandwidth。 Its efficiency and small size mean it could run on batteries and be integrated into consume
A new study suggests depression may soon be detectable through a simple blood test—by tracking how certain immune cells age。 Researchers found that accelerated aging in monocytes, a type of white blood cell, is closely tied to the emotional and cognitive symptoms of depression, like hopelessness and loss of pleasure, rather than physical symptoms s
For decades, relaxor ferroelectrics have powered everything from medical ultrasounds to sonar systems, yet their inner atomic structure remained a mystery—until now。 Researchers have finally mapped their three-dimensional structure in unprecedented detail, uncovering hidden patterns in how electric charges are arranged at the nanoscale。 The breakth
UK staff of Google’s AI research lab hope to block the use of the company’s artificial intelligence models in military settings
How research linking climate change and extreme weather events is being used in lawsuits
A new study suggests a surprisingly simple compound could help fight Alzheimer’s disease。 Researchers found that arginine—an inexpensive amino acid already considered safe—can reduce the buildup of toxic amyloid proteins in the brain, a hallmark of the disease。 In animal models, oral arginine not only lowered harmful protein deposits but also impro
A scorching, airless world just 48 light-years away is offering scientists a rare glimpse into the geology of distant planets。 Using the James Webb Space Telescope, researchers studied LHS 3844 b—a tidally locked “super-Earth” with a permanent dayside hot enough to melt metal—and discovered it’s a dark, barren rock with no atmosphere
Penn researchers have developed a smarter AI method for solving notoriously difficult inverse equations, which help scientists uncover hidden causes behind observable effects。 By introducing “mollifier layers” that smooth noisy data, they’ve made these calculations more stable and far less computationally demanding。 This could transform fields like
A strange kind of matter that “ticks” forever without energy input has just taken a major leap toward real-world use。 Known as a time crystal, this quantum system repeats its motion endlessly—like a clock that never winds down—and scientists have now managed to connect it to an external device for the first time。 By linking the time crystal to a ti
A surprising genetic twist shows that boosting a seemingly ordinary “housekeeping” gene can dramatically improve fruit quality without any trade-offs。 By increasing the activity of a tRNA-related gene in strawberries, researchers unlocked richer color, stronger aroma, and higher levels of health-boosting compounds like anthocyanins and terpenoids。
A new kind of memory device may finally solve the problem of overheating and battery drain in electronics。 By shrinking components to an extreme scale and redesigning their structure, researchers found a way to reduce energy loss instead of increasing it。 The result is a tiny memory unit that improves as it gets smaller—something once thought impos
