Investigating dense plasmas with positron waves
Astrophysical and lab-created plasmas under the influence of magnetic fields are the source of intense study. New research seeks to understand the dynamics of position waves traveling through these clouds of highly ionized gas......»»
NHTSA asks Tesla for more information about Calif. fatal crash
NHTSA has spent the last 18 months investigating how Tesla’s driver-assistance system Autopilot handles crash scenes involving fire trucks and other first-responder vehicles. It’s unclear whether the driver in the incident was using Autopilot......»»
Prisons should improve transparency in death investigations to improve prison safety, report finds
The UK Prisons and Probation Ombudsman (PPO) must improve transparency when investigating prisoner deaths, according to a new report and policy brief by prison safety experts at the University of Nottingham......»»
Quantifying the complex interplay behind heat waves
Unusually hot weather in India and Pakistan at the end of March; a long, warmer-than-average summer in central Europe; extreme December temperatures in northern Argentina, Uruguay and Paraguay: 2022 was definitely a year of heat waves. And there is c.....»»
Tapered optical fiber addresses challenge posed by Brillouin scattering
When optical beams, consisting of photons, travel through fibers, they cause vibrations that generate acoustic waves, consisting of phonons. The phenomenon, called Brillouin scattering, has been harnessed by researchers to optomechanically "couple" a.....»»
Investigating the nanomechanical properties of the surface layers of hair fibers
A project led by Ella Hudson, Ph.D. Researcher at The University of Sheffield, seeks to ascertain the contribution of the hair cuticle to the mechanical properties of the whole fiber......»»
Scientists observe high-speed star formation
Gas clouds in the Cygnus X Region, a region where stars form, are composed of a dense core of molecular hydrogen (H2) and an atomic shell. These ensembles of clouds interact with each other dynamically in order to quickly form new stars. That is the.....»»
Tropical seagrass meadows are sand factories that could protect coral reef islands from sea-level rise
Seagrasses are flowering plants that form dense underwater meadows in coastal waters worldwide, from the frigid seas of the Arctic to the warm shallows of the Caribbean. These meadows provide a refuge for young fish, food for grazing sea turtles and.....»»
Apple may be cutting contractors in an effort to slash costs
While Apple may have avoided the significant layoffs that have plagued other Big Tech companies like Amazon and Meta until now, it now seems that the company is quietly cutting ties with contractors.Apple ParkMass waves of layoffs have plagued tech g.....»»
Antarctica sea ice melts to a record low
The Antarctic Ocean area covered by ice has shrunk to a record low, exposing the thicker ice shelves buttressing Antarctica's ground ice sheet to waves and warmer temperatures, scientists reported Thursday......»»
Proposed quantum device may succinctly realize emergent particles such as the Fibonacci anyon
Long before Dr. Jukka Vayrynen was an assistant professor at the Purdue Department of Physics and Astronomy, he was a post-doc investigating a theoretical model with emergent particles in a condensed matter setting. Once he arrived at Purdue, he inte.....»»
Battery startup NanoGraf raises $65M to make lithium batteries more energy dense
Chicago's NanoGraf previously produced silicon anodes in Japan but took advantage of a 10 percent tax credit to start producing battery materials in the U.S......»»
Snow algae: Investigating how algal blooms impact mountain snowpack
Scott Hotaling, an Assistant Professor in the Department of Watershed Sciences in the Quinney College of Natural Resources, is exploring how the watermelon-tinted blooms of snow algae impact mountain snowpack—where they come from, what triggers a b.....»»
Scientists investigate an ancient boat buried under a pub car park
Nottingham scientists are co-leading a team investigating an ancient boat buried under a pub car park to find out where it came from and exactly how old it is......»»
How does a drying Great Salt Lake affect carbon cycling?
As water levels at the lake continue to decline, the complex natural systems the lake supports are shifting, too. Ecohydrologist Erin Rivers from the Quinney College of Natural Resources is investigating how shifting water levels at the Great Salt La.....»»
The secret lives of neutron stars
Astrophysicists use gravitational waves and light to trace genealogies of dead stars. Composite X-ray, visible-light, and radio image of the X-ray binary Circinus X-1. This object is a neutron star in mutual orbit with an ordinar.....»»
The Secret Lives of Neutron Stars
Astrophysicists are using gravitational waves and light to trace the genealogies of dead stars and reveal the history of the universe......»»
Quarks and gluons: The JADE experiment at DESY
A new paper in The European Physical Journal H (EPJ H) describes the JADE experiment at DESY in Hamburg, in which high-energy electron-positron collisions led to the discovery of the particle that holds quarks together to form protons and neutrons: t.....»»
Hubble is investigating mysterious “spokes” in Saturn’s rings
Saturn is famous for its beautiful rings, but these rings have a strange feature: spokes that appear intermittently. Now Hubble is on the case......»»
How Fiber Optic Cables Could Warn You of an Earthquake
By firing lasers through underground fibers, scientists can detect seismic waves and perhaps improve alerts—giving people precious time to prepare......»»
Goodbye flu, RSV, and COVID waves; hello, norovirus!
