Young minds are pushing the boundaries of origami, with a NYC student discovering a fold's strength and a Japanese student modeling complex folds inspired by nature. This research aids in developing new nature-inspired technologies.
The RNA World hypothesis posits RNA as early life's genetic material. A new model suggests asteroid impacts sterilized Earth until 4.4B years ago. Post-impact, hydrothermal vents fostered RNA's emergence around 4.33B years ago, predating LUCA by ~130M years, offering precise timeline insights.
A massive volcanic eruption in Chile buried a landscape, preserving clues about Andean mountain formation. New research suggests a slow, steady uplift of the crust over millions of years.
Researchers estimated T. rex's body temperature to be 97.3°F (36.3°C), comparable to humans and elephants, indicating it was a warm-blooded, active predator. This finding impacts understanding of its habitat and behavior during the Cretaceous period.
Scientists developed a new technique to read ancient papyrus scrolls carbonized by volcanic eruptions. By first scanning for leaded ink, they can then use X-rays and AI to decipher the text, potentially revealing lost wisdom from thinkers.
New research suggests a surprising pause in gray matter reduction during menopause, unlike changes seen in menarche and pregnancy. The study highlights the critical need for more research into how hormonal shifts impact the brain throughout a woman's life.
A pristine mastodon molar, identified as a Pacific mastodon, was unearthed in California. This significant fossil from the last glacial epoch provides valuable insights into prehistoric North America and species differentiation.
A new camping tent utilizes magnetoelastic fabric to generate supplementary electricity from wind and movement, not just sunlight. Ideal for low-power devices in off-grid locations, it's not a grid replacement. Future research will focus on durability, real-world output, and affordability.
Discover why the Arctic solar eclipse path seems to reverse, a visual trick of flat maps and Earth's rotation. Learn about umbra and penumbra, and the true west-to-east path of the moon's shadow.
The LatAm-FINGERS trial demonstrates significant cognitive improvement with culturally adapted lifestyle interventions, exceeding previous studies. Targeting Lancet Commission's risk factors, it offers new hope for scalable dementia prevention, particularly for those most in need.
New research highlights Mexico's pivotal role in ancient mammal migration between North and South America. Prior to the Isthmus of Panama forming, Mexico served as a 'holding pen,' allowing northern species to adapt and diversify before entering South America.
Katalyst's mission to refuel NASA's aging Swift Observatory is delayed due to unexpected spacecraft rotation issues. Teams are working to stabilize the spacecraft and reschedule the rendezvous before Swift falls back to Earth.
Dr. Selwyn Rogers Jr. discusses treating gun violence as a public health crisis, detailing Chicago's trauma center fight, hospital-based prevention, and the vital role of lived experience. He emphasizes holistic care, community solutions, and hope for a solvable future.
Canadian wildfires, fueled by lightning and human activity, are becoming more extreme due to climate change. These massive fires, though few, destroy vast areas and create hazardous smoke impacting air quality across North America. Fire management is increasingly challenging.
Truly round animals are rare, especially on land, due to gravity and survival needs. Sea creatures like lumpsuckers and sea urchins come closest, often using spherical shapes for defense. Land animals like rabbits often only appear round due to fur, though some curl for protection or heat retention.
A meteorite that crashed through a New Jersey home has yielded the building blocks of life, including amino acids and prebiotic molecules. Researchers found it came from an ancient, underdeveloped solar system world and contained preserved bits from a primitive planet's salty surface.
A four-legged robot, KAIST CANINE, uses an APT-RL AI system to adapt its gait (trot/bound) to diverse terrains and obstacles without human input. Trained with trajectory optimization and reinforcement learning, it shows promise for navigating disaster zones.
