Astronomers detect a cosmic “heartbeat” in pulsar signals

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by overlapping waves from supermassive black holes. This subtle modulation could help scientists tell whether the waves stem from ancient cosmic inflation or nearby black hole binaries, potentially identifying the true source of spacetime’s gentle vibrations.

MIT scientists find metals hold secret atomic patterns

MIT researchers found that metals retain hidden atomic patterns once believed to vanish during manufacturing. These patterns arise from microscopic dislocations that guide atoms into preferred arrangements instead of random ones. The discovery introduces a new kind of physics in metals and suggests engineers can exploit these patterns to enhance material performance in demanding environments.

Your brain’s power supply may hold the key to mental illness

Groundbreaking Harvard research is exposing hidden energy failures inside brain cells that may drive major psychiatric conditions. By studying reprogrammed neurons, scientists are revealing how cellular metabolism shapes mood, thought, and cognition. The work calls for abandoning rigid diagnostic categories in favor of biology-based systems that reflect true complexity. It marks a decisive shift toward preventive and precision mental healthcare.

JWST may have found the Universe’s first stars powered by dark matter

New observations from the James Webb Space Telescope hint that the universe’s first stars might not have been ordinary fusion-powered suns, but enormous “supermassive dark stars” powered by dark matter annihilation. These colossal, luminous hydrogen-and-helium spheres may explain both the existence of unexpectedly bright early galaxies and the origin of the first supermassive black holes.

Scientists build artificial neurons that work like real ones

UMass Amherst engineers have built an artificial neuron powered by bacterial protein nanowires that functions like a real one, but at extremely low voltage. This allows for seamless communication with biological cells and drastically improved energy efficiency. The discovery could lead to bio-inspired computers and wearable electronics that no longer need power-hungry amplifiers. Future applications may include sensors powered by sweat or devices that harvest electricity from thin air.

Popular hair-loss pill linked to depression and suicide

Finasteride, a common hair-loss drug, has long been tied to depression and suicide, but regulators ignored the warnings. Prof. Mayer Brezis’s review exposes global data showing psychiatric harm and a pattern of inaction by Merck and the FDA. Despite its cosmetic use, the drug’s effects on brain chemistry can be devastating. Brezis calls for urgent regulatory reforms and post-marketing studies to protect public health.

Decades-old photosynthesis mystery finally solved

Scientists from the Indian Institute of Science (IISc) and Caltech have finally solved a decades-old mystery about how photosynthesis really begins. They discovered why energy inside plants flows down only one of two possible routes — a design that lets nature move sunlight with astonishing precision. Using advanced computer simulations, the researchers showed that one branch has a much higher energy barrier, blocking electrons from moving freely.

New research reveals how ADHD sparks extraordinary creativity

Researchers have discovered that ADHD’s hallmark mind wandering might actually boost creativity. People who deliberately let their thoughts drift scored higher on creative tests in two large studies. The findings hint that mindful management of mental drift could turn ADHD’s challenges into creative strengths.

Ancient humans in Italy butchered elephants and made tools from their bones

Researchers in Italy discovered 400,000-year-old evidence that ancient humans butchered elephants for food and tools. At the Casal Lumbroso site near Rome, they found hundreds of bones and stone implements, many showing impact marks from butchery. The findings reveal a consistent prehistoric strategy for resource use during warmer Middle Pleistocene periods.

Breakthrough compounds may reverse nerve damage caused by multiple sclerosis

Researchers have identified two compounds, K102 and K110, that could repair the nerve damage from multiple sclerosis. These drugs help regenerate the protective myelin sheath and balance immune responses. Licensed by Cadenza Bio, the discovery represents a leap from lab research to potential clinical therapy. If successful, it could transform how neurodegenerative diseases are treated.

Scientists unearth a 112-million-year-old time capsule filled with ancient insects

Researchers have unearthed South America’s first amber deposits containing ancient insects in an Ecuadorian quarry, offering a rare 112-million-year-old glimpse into life on the supercontinent Gondwana. The amber, found in the Hollín Formation, preserved a diverse range of insect species and plant material, revealing a humid, resin-rich forest teeming with life.

12,000-year-old rock art found in Arabia reveals a lost civilization

Archaeologists in Saudi Arabia discovered over 170 ancient rock engravings that may be among the earliest monumental artworks in the region. Created between 12,800 and 11,400 years ago, the massive figures were carved when water and life returned to the desert. The art likely marked territories and migration routes, revealing social and symbolic sophistication. Artifacts found nearby show early Arabian peoples connected to distant Neolithic communities.

USC engineers just made light smarter with “optical thermodynamics”

USC engineers have developed an optical system that routes light autonomously using thermodynamic principles. Rather than relying on switches, light organizes itself much like particles in a gas reaching equilibrium. The discovery could simplify and speed up optical communications and computing. It reimagines chaotic optical behavior as a tool for design rather than a limitation.
