A new study found that, out of 180 apps examined, 45 collect photos, and 12 gather videos — and most of these apps belong to top apparel giants.
Heart tumor or cardiac tumor is a rare condition that is prevalent in adults. Though the exact cause is unknown, genetics could play a role.
Your personal information may have been leaked in the ‘Mother of all Breaches’ (MOAB), cybersecurity researchers have warned.
Over 26 billion personal records have been exposed, in what researchers believe to be the biggest-ever data leak.
Sensitive information from several sites including Twitter, Dropbox, and Linkedin was discovered on an unsecured page.
Advanced Science is a high-impact, interdisciplinary science journal covering materials science, physics, chemistry, medical and life sciences, and engineering.
Insights from NASA ’s IXPE mission have transformed our understanding of particle acceleration in black holes, using the microquasar SS 433 as a case study to reveal aligned magnetic fields within its jets.
The powerful gravity fields of black holes can devour whole planets’ worth of matter – often so violently that they expel streams of particles traveling near the speed of light in formations known as jets. Scientists understand that these high-speed jets can accelerate these particles, called cosmic rays, but little is definitively known about that process.
Recent findings by researchers using data from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) spacecraft give scientists new clues as to how particle acceleration happens in this extreme environment. The observations came from a “microquasar,” a system comprised of a black hole siphoning off material from a companion star.
The ‘ten electron’ rule provides guidance for the design of single-atom alloy catalysts for targeted chemical reactions.
A collaborative team across four universities have discovered a very simple rule to design single-atom alloy catalysts for chemical reactions. The ‘ten electron rule’ helps scientists identify promising catalysts for their experiments very rapidly. Instead of extensive trial and error experiments of computationally demanding computer simulations, catalysts’ composition can be proposed simply by looking at the periodic table.
Single-atom alloys are a class of catalysts made of two metals: a few atoms of reactive metal, called the dopant, are diluted in an inert metal (copper, silver, or gold). This recent technology is extremely efficient at speeding up chemical reactions but traditional models don’t explain how they work.
Eleven astronauts and cosmonauts from around the world are living and working together aboard the International Space Station (ISS) today, January 22. The four Axiom Mission 3 (Ax-3) private astronauts met the seven Expedition 70 crew members on Saturday beginning two weeks of dual operations.
The Ax-3 crew spent the weekend getting familiar with space station systems and emergency procedures before starting Monday with a full schedule of science and media activities. Ax-3 Commander Michael López-Alegría joined Pilot Walter Villadei and studied how microgravity affects the biochemistry of neurodegenerative diseases such as Alzheimer’s to improve health on Earth and in space. The duo later inserted samples into a fluorescence microscope for a study seeking to prevent and predict cancer diseases to protect crews in space and humans on Earth.
A study using Sloan Digital Sky Survey data reveals that the Universe may be younger than estimated, challenging conventional cosmological models by analyzing satellite galaxy motions around massive groups.
In standard cosmological models, the formation of cosmological structures begins with the emergence of small structures, which subsequently undergo hierarchical merging, leading to the formation of larger systems. As the Universe ages, massive galaxy groups and clusters, being the largest systems, tend to increase in mass and reach a more dynamically relaxed state.
The motions of satellite galaxies around these groups and clusters provide valuable insights into their assembly status. The observations of such motion offer crucial clues about the age of the Universe.
The Defense Advanced Research Projects Agency launched a second iteration of its Tools Competition to discover artificial intelligence-enabled technologies that can aid data science and other forms of adult learning.
The agency said Monday that the new program aims to upskill and reskill adults in science, technology, engineering and mathematics and similarly complex areas, preparing them for the 21st century labor landscape.
The opportunity is open to digital learning platform experts, technologists, researchers, students and educators who can propose AI tools that can provide feature tutoring and self-directed learning. The resulting platform may leverage AI or large language models.
We experimentally demonstrate optoacoustic cooling via stimulated Brillouin-Mandelstam scattering in a 50 cm long tapered photonic crystal fiber. For a 7.38 GHz acoustic mode, a cooling rate of 219 K from room temperature has been achieved. As anti-Stokes and Stokes Brillouin processes naturally break the symmetry of phonon cooling and heating, resolved sideband schemes are not necessary. The experiments pave the way to explore the classical to quantum transition for macroscopic objects and could enable new quantum technologies in terms of storage and repeater schemes.
