The first detailed map of space within about 1,000 light years of Earth places the solar system in the middle of a large hole that pierces the plane of the galaxy, perhaps left by an exploding star one or two million years ago.
The new map, produced by University of California, Berkeley, and French astronomers, alters the reigning view of the solar neighborhood. In that picture, the sun lies in the middle of a hot bubble – a region of million-degree hydrogen gas with 100-1,000 times fewer
University of California, Berkeley’s RHESSI satellite, launched last year by NASA, was snapping X-ray pictures of solar flares in December when it caught an extremely bright background gamma-ray burst, revealing a novel physical feature of these gamma rays – their polarization.
The result sheds new light on the driving force behind these mysterious explosions.
Gamma-ray bursts are mysterious flashes of gamma-ray photons that pop off about once a day randomly in the sky, briefl
Scientists have discovered that seaweeds defend themselves from specific pathogens with naturally occurring antibiotics. The finding helps explain why some seaweeds, sponges and corals appear to avoid most infections by fungi and bacteria, according to a study published May 19 in the Proceedings of the National Academy of Sciences.
“Seaweeds live in constant contact with potentially dangerous microbes, and they have apparently evolved a chemical defense to help resist disease,” said lead author
Ohio University engineers are leading one of the first comprehensive efforts to examine how fuel cell technology could pave the way for cleaner coal-fired power plants. Supported by a $4 million U.S. Department of Energy grant secured by the Ohio Congressional delegation, the project aims to find ways to use coal – the environmentally dirtiest but most abundant fossil fuel in the world — to harness high-efficiency fuel cells.
Most government-sponsored energy research is focused on using nat
Single-molecule switches have the potential to shrink computing circuits dramatically, but new results from the Arizona State University lab that first described how to wire a single molecule between gold contacts now show that laboratory-standard wired molecules have an unavoidable tendency to “blink” randomly.
In the May 30, 2003, Science, Stuart Lindsay and colleagues identify the cause of this blinking behavior as random, temporary breaks in the chemical bond between the wired molecule
Tiny blood vessels, viewed beneath a mouse’s skin with a newly developed application of multiphoton microscopy, appear so bright and vivid in high-resolution images that researchers can see the vessel walls ripple with each heartbeat — 640 times a minute.
The capillaries are illuminated in unprecedented detail using fluorescence imaging labels, which are molecule-size nanocrystals called quantum dots circulating through the bloodstream. Quantum dots are microscopic metal or semiconductor
Operations teams have confirmed NASA’s mission to “touch” the Sun survived its record-breaking closest approach to the solar surface on Dec. 24, 2024. Breaking its previous record by flying just…
At the Berlin synchrotron radiation source BESSY II, the largest magnetic anisotropy of a single molecule ever measured experimentally has been determined. The larger this anisotropy is, the better a…
