Quasi-periodic oscillations detected in pulsar LMC X-4
Using ESA's XMM-Newton telescope, Indian astronomers have performed X-ray observations of a binary X-ray pulsar known as LMC X-4. The observational campaign resulted in the detection of quasi-periodic oscillations (QPOs) in this source. The finding i.....»»
Scientists use FAST to discover a new population of "dwarf" pulses
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Prof. Han Jinlin from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) has detected distinct "dwarf pulses" from a bright.....»»
Phishers use QR codes to target companies in various industries
A phishing campaign using QR codes has been detected targeting various industries, with the aim to acquire Microsoft credentials. “The most notable target, a major Energy company based in the US, saw about 29% of the over 1000 emails containing.....»»
Astronomers confirm Maisie"s galaxy is among earliest ever observed
Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings are published in the j.....»»
New massive brown dwarf discovered
Astronomers report the discovery of a new massive brown dwarf using the Zwicky Transient Facility (ZTF). The newly detected object is about 80 times more massive than Jupiter and orbits a low-mass star. The finding was detailed in a paper published J.....»»
Avian botulism detected at California"s resurgent Tulare Lake, raising concern for migrating birds
Wildlife authorities have detected avian botulism at California's resurgent Tulare Lake, raising concerns about potential die-offs during fall bird migrations......»»
Webb telescope reveals colors of Earendel, most distant star ever detected
Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted the most distant star.....»»
After 15 years, pulsar timing yields evidence of cosmic background gravitational waves
The universe is humming with gravitational radiation—a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it......»»
Stealth swimmers: The fish that hide behind other fish to hunt
A new study provides the first experimental evidence that the trumpetfish, Aulostomus maculatus, can conceal itself by swimming closely behind another fish while hunting—and reduce the likelihood of being detected by its prey. The study, involving.....»»
NASA helps spot wine grape disease from skies above California
In a case study, scientists detected the costly infection in cabernet sauvignon grapevines before they showed symptoms visible to the human eye......»»
A solar eruption was detected on Earth, the moon, and even Mars
Scientists recently reported on a solar event that was detectable not only on Earth, but also on the moon and Mars......»»
Researchers propose new method for pulsar timing and radio-frequency interference mitigation
Radio frequency interference (RFI) caused by human communication techniques (e.g., satellites, base stations, and navigation radars) can significantly distort shapes of multichannel time-frequency radio signals. Subsequent astrophysical measurements,.....»»
Quantum-enhanced non-interferometric quantitative phase imaging
Optical phase retrieval and imaging appear in a wide variety of science fields, such as imaging of quasi-transparent biological samples or nanostructures metrological characterization, for example, in the semiconductor industry. At a fundamental leve.....»»
If rogue planets are everywhere, how could we explore them?
At one time, astronomers believed that the planets formed in their current orbits, which remained stable over time. But more recent observations, theory, and calculations have shown that planetary systems are subject to shake-ups and change. Periodic.....»»
The PLATO mission could be the most successful planet hunter ever, scientists believe
In 2026, the European Space Agency (ESA) will launch its next-generation exoplanet-hunting mission, the PLAnetary Transits and Oscillations of stars (PLATO)......»»
Tailoring quantum oscillations of a Bose-Einstein condensate of excitons as qubits
What plagues quantum upscaling? Most quantum computing devices are dependent on using complex physical phenomena that are either very short-lived (~10-12 seconds) and/or only survive at ultra-low temperatures (e.g., 10-3 to 10-6 Kelvin) and/or requir.....»»
Two additional exoplanets detected in a nearby planetary system
By conducting radial velocity (RV) follow-up observations of the GJ 367 planetary system with the High Accuracy Radial velocity Planet Searcher (HARPS), an international team of astronomers has detected two additional alien worlds, at least four time.....»»
PFAS detected in blood of horses and dogs too near factory in eastern North Carolina
Debra Stewart walked toward a horse paddock with a bag of carrots in hand. Whisper, a splashed chocolate and white paint horse, met her at the fence......»»
Social media roundup: CSAM on Mastodon; Zuckerberg faces contempt charge; Twitter’s bank plans
An investigation by the Stanford Internet Observatory has found worrying volumes of CSAM on Mastodon. Of particular concern is that the child sexual abuse material included many known examples that should have been automatically detected by digital.....»»
Spontaneous quasi-crystal self-assembly observed using tiny vibrating magnetic spheres
A team of physicists at Université Paris-Saclay has, for the first time, observed spontaneous quasi-crystal self-assembly. The observation occurred during an experiment they were conducting with tiny vibrating magnetic spheres. The team has written.....»»
A tailor-made magnetic vortex: A closer look at a special kind of quasiparticle
Skyrmions are microscopic magnetic vortices that can form in certain materials. First detected in 2009, they are of interest to researchers because they could be harnessed for new forms of data storage. As theoreticians predicted, there are also so-c.....»»
