Phys.org / Great hammerheads maintain peak hunting across wide temperature swings, biologging data suggest
Most predators slow down when ocean temperatures shift. Great hammerhead sharks don't—not significantly anyway. These ocean predators are masters of the "thermal hustle," maintaining peak hunting performance across a surprisingly ...
Phys.org / NASA probe data suggests a more complex sun's magnetic engine
A Southwest Research Institute-led study found that protons and heavy ions react differently to solar magnetic reconnection events, revealing a more complex magnetic engine powering the solar wind. Magnetic reconnection converts ...
Tech Xplore / New memory chip survives temperatures hotter than lava
The electronics inside your phone, your car, and every satellite currently orbiting Earth share one critical weakness: heat. Push them past about 200 degrees Celsius and they start to fail. For decades, that thermal ceiling ...
Phys.org / Crushing soda cans and the mathematics of corrugation formation
Many people have likely found themselves watching oddly satisfying videos of random objects being squashed by a powerful hydraulic press, but rarely do people consider why things squash the way they do. One object that caught ...
Phys.org / Physicist recreates neutron star reaction, reveals how explosive stars forge elements
A Mississippi State physicist has produced a direct laboratory measurement of a key nuclear reaction believed to occur during explosive bursts on neutron stars. These bursts forge heavier elements—the building blocks of planets ...
Tech Xplore / Apple's 50-year odyssey has redefined technology, pop culture and comeback stories
A scrawny hippie and a nerdy engineer who became prank-playing friends vowed to change the world when they founded a Silicon Valley startup on April Fools' Day 50 years ago and then—no joke—pulled it off.
Phys.org / Chiral metasurfaces guide twisted light into free space
Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew ...
Phys.org / Engineers introduce first synthetic charged domain wall in 2D material
In a first for the field, materials scientists from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have interfaced two materials to artificially generate a highly conductive ferroelectric ...
Medical Xpress / Twin study suggests genes explain most of the link between IQ and socioeconomic status
New twin research shows that innate IQ plays a major role in predicting your future socioeconomic status. The study, which follows twins during the crucial early adult years, reinforces the view that heredity and genes shape ...
Medical Xpress / Cysteine pathways help T cells choose between multiplying and attacking tumors
A research team from the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health has discovered how the immune system's CD8+ T cells ...
Medical Xpress / Chemical compound clears misfolded tau, protects neurons in a model of frontotemporal dementia
New research from Washington University School of Medicine in St. Louis adds to growing evidence that helping brain cells break down and eliminate their own cellular waste is a promising treatment strategy for a variety of ...
Phys.org / Tracking the footsteps of West Africa's prehistoric metalworkers
The discovery of a 2,400-year-old metalworking workshop in Senegal provides new insights into the history of iron production in Africa. Despite decades of archaeological research, the origins of iron metallurgy in sub-Saharan ...
