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.
A chemical and dental analysis of 152 individuals on St. Helena reveals many originated from coastal and inland West Central Africa, shedding light on their childhood displacement and enslavement.
A man with a complex medical history presents with acute symptoms, leading to a diagnosis of secondary syphilis with early neurosyphilis. The case highlights the delayed and varied manifestations of the infection and its treatment challenges.
A US OMB proposal allowing political appointees to control science funding threatens research, mirroring Soviet Lysenkoism which caused starvation & scientific decline. It impacts mRNA research, public health, and academic freedom, risking US scientific leadership.
Experimental drug targeting interleukin-11 reduces ovarian stiffness in older mice, doubling conception rates and increasing litter size. This intervention offers hope for extending female fertility.
NASA's ISS Cold Atom Lab cools rubidium & potassium to near absolute zero, creating Bose-Einstein condensates to study quantum mechanics in microgravity. This enables precise measurements and advances future space-based quantum technologies.
Physicists explore 'strange metals' exhibiting unusual conductivity, challenging fundamental ideas of electricity flow. New theories like holography and SYK models offer insights, potentially leading to room-temperature superconductivity.
A study on onion tearing and chemosensory sensitivity reveals a disconnect: those self-reporting more tears and better smell often don't perform better on actual sniff tests. This highlights the unreliability of self-assessed sensory abilities.
The AMOC, a vital ocean current, is weakening, causing a "cold blob" near Greenland. Research links this North Atlantic Warming Hole to reduced ocean heat transport, not surface changes, warning a potential AMOC tipping point poses significant, irreversible climate change risks.
Synesthesia is a condition where sensory input triggers other senses, like seeing colors with sounds or numbers. Examples include grapheme-color and chromesthesia.
The Chicxulub asteroid impact 66 million years ago created a vast, hot, underground hydrothermal system that sustained microbial life for at least 8 million years, longer than previously thought.
An AI model refuted Paul Erdős's 80-year-old unit distance conjecture, creating a complex counterexample using algebra & number theory. This breakthrough excites mathematicians but raises concerns about AI's transparency, reliability, and potential impact on open access in math.
