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
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
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
Artemis II proved NASA’s deep space systems are ready for the next leap。 Orion survived its high-speed return with improved heat shield performance and pinpoint landing accuracy, while the SLS rocket nailed its trajectory。 Even the launch pad upgrades paid off, with minimal damage despite the powerful liftoff
After centuries of mystery, scientists are edging closer to uncovering Leonardo da Vinci’s biological secrets。 A massive 30-year effort has mapped his family across 21 generations, identified living male descendants, and even confirmed shared DNA markers that stretch back to the Renaissance。 Meanwhile, excavations at a family tomb in Vinci could pr
The Trump administration, which took a noninterventionist approach to artificial intelligence, is now discussing imposing oversight on A。 models before they are made publicly available
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
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
Creatine might be famous in the gym, but its real story is far more interesting。 Naturally produced in the body, it helps power cells by rapidly regenerating ATP—the fuel that keeps muscles, the brain, and even the heart running during intense activity。 Supplementing with creatine can boost short bursts of physical performance and may even support
