calculate the total cumulative load of the city’s built environment. Excluding infrastructure like bridges, rail lines, and roads, the team estimated the weight of New York’s buildings and their contents at approximately 1.68 trillion pounds (762...

Discover the most influential female authors of the 20th century, including black and African American writers, Christian authors, and feminist icons. The literary contributions of female authors have significantly shaped the modern literary landscape,...

Researchers have found a way to turbocharge the cell’s tiny power plants using engineered nanomaterials, opening a new path toward treating hard‑to‑fix mitochondrial diseases and boosting regenerative medicine. Every cell in your body runs on energy....

Recent research suggests that complex cells were already surprisingly sophisticated long before they gained mitochondria, reshaping how scientists think about the origin of animals, plants, and fungi. If you imagine the first complex cells on Earth,...

A new analysis shows nitrous oxide can ease depressive symptoms within hours. The effect fades within a week after one session, but repeated treatments may extend the benefit. Depression continues to affect millions of people worldwide, and many...

As megaconstellations flood low Earth orbit, a new “CRASH Clock” reveals how close we may be to a chain reaction of satellite collisions that could disrupt life on Earth. If you checked the weather today, used GPS to navigate, watched a live sports...

A new survey has identified 529 quiet, mature K dwarf “Goldilocks stars” near the Sun, offering the most stable radiation environments known and creating an unprecedented list of prime targets in the search for habitable exoplanets. For generations,...

A landmark international study finds that nearly everyone who develops heart disease already has poorly controlled risk factors years before diagnosis, overturning the idea that cardiovascular disease appears suddenly or without cause. Heart disease is...

A large genetic study suggests that people with naturally higher lifelong caffeine levels tend to have lower body fat and a reduced risk of type 2 diabetes, offering new insight into how this everyday stimulant may influence long-term metabolic health....

A revolutionary new X-ray telescope has turned its gaze toward the most massive structures in the universe to solve a ten-year-old mystery: is dark matter hiding in plain sight as a faint, unexplained glow? The universe we see is only a tiny fraction...

Ashwagandha is everywhere right now, but its active compounds are hard to produce. Scientists have now engineered yeast to make them instead, changing how these herbal ingredients could be studied and scaled. Ashwagandha is not new. It has been used in...

After fixing hydrogen fuel leaks, NASA’s massive Artemis moon rocket developed a helium system problem, forcing another return to the hangar and delaying the first crewed lunar mission in over 50 years. For the first time in more than half a century,...

A new lab study finds sperm struggle to navigate and fertilize eggs in simulated microgravity, hinting at hidden reproductive challenges for long-term space travel. For decades, space agencies have focused on propulsion, radiation shielding, and...

A large international analysis links Parkinson’s disease to disrupted gut bacteria that reduce key B vitamins, weakening intestinal defenses and potentially accelerating brain damage. Long before tremors begin or movement slows, something subtle may...

NASA has entered the final countdown for Artemis II, a historic mission set to carry astronauts around the Moon for the first time in more than 50 years, marking a new era of human space exploration. For the first time in more than half a century, the...

Scientists suggest Titan could become humanity’s next frontier, eyeing the moon as a future destination for human exploration. A growing chorus of scientists and engineers is turning the once‑far‑off notion of landing humans on Titan, Saturn’s largest...

Archaeologists uncover a unique ancient cave at a construction site, revealing rare clues about life from hundreds of thousands of years ago. A hidden cavern beneath the hills outside Fureidis in northern Israel has yielded a suite of stone implements,...

Roman shipwreck in Lake Neuchâtel reveals 2,000‑year‑old cache of weapons, wagons and trade goods, shedding light on ancient commerce. A team of divers exploring Lake Neuchâtel uncovered a massive Roman cargo that sank between 20 and 50 AD, leaving...

SpaceX readies Starship Flight 13, adding key upgrades to fix the glitches that halted the previous launch. SpaceX is targeting a launch of Starship Flight 13 as early as July 16, a test that could become one of the company’s most consequential...

Astronomers may have found the first exomoon beyond our solar system – a Jupiter‑mass companion orbiting a brown dwarf. Using the European Southern Observatory’s Very Large Telescope, astronomers have identified a Jupiter‑sized body orbiting a brown...
