Fermi spots a supernova"s "fizzled" gamma-ray burst
On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record.....»»
Why do cats and dogs get "the zoomies"?
Does your cat or dog suddenly get a burst of energy and perform athletic feats around the house that would make even a gold medalist jealous? Welcome to the world of zoomies......»»
NASA"s Fermi detects first gamma-ray eclipses from "spider" star systems
Scientists have discovered the first gamma-ray eclipses from a special type of binary star system using data from NASA's Fermi Gamma-ray Space Telescope. These so-called spider systems each contain a pulsar—the superdense, rapidly rotating remains.....»»
GHz burst mode femtosecond laser pulses can create unique two-dimensional periodic surface nanostructures
Scientists working on laser application at the RIKEN Center for Advanced Photonics (RAP) have demonstrated that GHz burst mode femtosecond laser pulses can create unique two-dimensional (2D) laser-induced periodic surface structures (LIPSS) on silico.....»»
Study suggests a paradigm shift in our understanding of gamma ray bursts
Matter outflows in the form of jets are observed in astronomical systems at fast, medium and slow speeds. The fastest jets are highly relativistic, and travel very close to the speed of light. The origin, as well as many properties of the jets, is un.....»»
How Big Tech"s pandemic bubble burst
In January 2021, Microsoft CEO Satya Nadella spoke in lofty terms about how the first year of the pandemic had sparked a staggering shift toward online services, benefiting his company in the process. "What we have witnessed over the past year is the.....»»
How stray logs in Puget Sound turn industrial shorelines green
Squinting out the windowed wheelhouse of the ship he's helmed for two decades, Captain Skip Green spots something several hundred yards in the distance......»»
20 years ago, vast bushfires razed Canberra"s suburbs—and bushfire science was never the same
It has been 20 years to the day since bushfires burst out of the Brindabella Ranges and into the suburbs of our nation's bush capital. Four lives were lost, many people were injured and more than 500 homes were destroyed......»»
Harber London Commuter Backpack review: Fashion meets tech
Made from leather and sustainable fabric, Harber London's Commuter Backpack is, in a word, sophisticated. Fashion, in this case, does come with some trade-offs.Harper London Commuter BackpackThis stylish, general-purpose bag with spots for a 16-inch.....»»
Cosmic burst probes Milky Way"s halo
Astronomers have used an intense burst of radio waves originating from a nearby galaxy to inspect the halo of gas cocooning our own Milky Way galaxy. The scientists studied the way that the light of the so-called fast radio burst, or FRB, was dispers.....»»
NASA"s retired Compton mission reveals superheavy neutron stars
Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into a black hole. This fleeti.....»»
Astronomers spot unusual stellar explosion rich in oxygen and magnesium
A study led from the University of Turku, Finland, discovered a supernova explosion that expands the understanding of the later life stages of massive stars......»»
James Webb spots early galaxies similar to our Milky Way
Astronomers have used Webb to discover some of the earliest galaxies with a feature called stellar bars, making them similar to our Milky Way......»»
Researchers inspect gamma-ray flares of the blazar 3C 279
Using NASA's Fermi spacecraft, Chinese astronomers have investigated the variability and spectral behavior of gamma-ray flares in a distant blazar known as 3C 279. Results of the study, presented in a paper published in the Publications of the Astron.....»»
Mysterious gamma-ray emitting bubbles around the center of the Milky Way explained
A scientist from Tokyo Metropolitan University has shown that large gamma-ray-emitting bubbles around the center of the Milky Way were produced by fast, outward-blowing winds and an associated "reverse shock." Numerical simulations successfully repro.....»»
What Just Happened
For those of you older than 40, it sort of felt like 2000. If you are younger than 40, a massive tech bubble just burst. I expect you know that. For the past six months, many VCs have been podcasting, tweeting, publicly writing, … and generally.....»»
Study observes Luttinger liquid behavior in a quasi-2D system
Luttinger liquids are usually paramagnetic materials exhibiting non-Fermi liquid behavior, such as molybdenum oxides. These "liquids" and their fascinating properties had so far been only observed in 1D and quasi-1D compounds, such as blue bronze A0......»»
High-speed, high-sensitivity terahertz detection using graphene transistor
On the electromagnetic spectrum, which comprises everything from radio waves to X-rays and gamma rays, there exists a deadzone where conventional electronic devices can hardly operate. This deadzone is occupied by terahertz waves......»»
