Quasi-periodic oscillation detected in blazar PKS 0405-385
By analyzing the historical light curve of blazar PKS 0405-385 from NASA's Fermi spacecraft, Chinese astronomers have detected quasi-periodic oscillation from this source. The discovery, presented in a paper published May 5 on arXiv.org, could shed m.....»»
Detecting nanoplastics in fractions of a second using modified Raman spectroscopy
Microplastics are tiny, barely visible plastic particles that can harm the environment, for example, if they are eaten by animals. However, it has been difficult to assess the effect of even smaller particles, which can hardly be detected using conve.....»»
We"ve detected a star barely hotter than a pizza oven—the coldest ever found to emit radio waves
We have identified the coldest star ever found to produce radio waves—a brown dwarf too small to be a regular star and too massive to be a planet......»»
Microsoft takes pains to obscure role in 0-days that caused email breach
Critics also decry Microsoft's "pay-to-play" monitoring that detected intrusions. Enlarge (credit: Getty Images | Aurich Lawson) On Friday, Microsoft attempted to explain the cause of a breach that gave hackers working f.....»»
Astronomers discover a luminous nuclear transient
Using NASA's Swift spacecraft, an international team of astronomers has discovered a luminous and slowly-evolving nuclear transient event. The origin of the newly detected transient, designated Swift J221951-484240, is yet to be determined. The findi.....»»
New breakthrough shows how short pulses of light destroy particles
Polaritons are a peculiar state, a kind of quasi-particles consisting of part-light and part-matter that can bring unexpected abilities to conventional chemical reactions. New research from Umeå University and others reveals that when the polaritons.....»»
Impact of film thickness in laser-induced periodic structures on amorphous Si films
Since the scientists at Bell Labs invented the world's first transistor in December 1947, a revolution in microelectronics technology has profoundly affected lifestyles worldwide. As electronics get smaller and smaller, it is a challenge to find an e.....»»
Astronomers use dead stars to measure gravitational waves produced by ancient black holes
An international team of astronomers has detected a faint signal of gravitational waves reverberating through the universe. By using dead stars as a giant network of gravitational wave detectors, the collaboration—called NANOGrav—was able to meas.....»»
Astronomers puzzled by "planet that shouldn"t exist"
The search for planets outside our solar system—exoplanets—is one of the most rapidly growing fields in astronomy. Over the past few decades, more than 5,000 exoplanets have been detected and astronomers now estimate that on average there is at l.....»»
Models provide new insights into relationship between Asia-Pacific upper-tropospheric temperatures and precipitation
Pacific Oscillation (APO) is a recently identified atmospheric teleconnection pattern in the Asia-Pacific sector characterized by a seesaw vibration of upper-tropospheric temperatures between Asia and the North Pacific. Teleconnections are links betw.....»»
In a First, Scientists See Neutrinos Emitted by the Milky Way
The disk of our galaxy was long thought to produce these ghostly high-energy particles, but they haven’t been detected until now.....»»
First "ghost particle" image of Milky Way galaxy captured by scientists: Neutrinos detected by IceCube
Our Milky Way galaxy is an awe-inspiring feature of the night sky, viewable with the naked eye as a horizon-to-horizon hazy band of stars. Now, for the first time, the IceCube Neutrino Observatory has produced an image of the Milky Way using neutrino.....»»
The Universe Is Abuzz with Giant Gravitational Waves, and Scientists Just Heard Them (Maybe)
Researchers, using the galaxy as a detector, believe they have detected gravitational waves from monster black holes for the first time......»»
