Engineers have created a new machine learning-assisted method that could make quantum photonic circuit development more efficient by rapidly pre-selecting these solid-state quantum emitters.
Eating less meat and dairy products in favor of plant-based proteins like those found in grains, legumes and nuts could make a huge difference in how much carbon dioxide reaches the atmosphere.
Scientists describe the quirky behavior of one such magnetic topological insulator. The new article includes experimental evidence that intrinsic magnetism in the bulk of manganese bismuth telluride (MnBi2Te4) also extends to the electrons on its electrically conductive surface. Such materials could be just right for making qubits, but this one doesn't obey the rules.
A class of antibiotic molecules called pleicomacrolides inhibit the Nef protein, which HIV uses to evade the body's immune system.
New research reveals in detail how the nucleosomes inside our cells block cGAS from unintentionally triggering the body's innate immune response to our own DNA.
The UNC School of Medicine lab of Camille Ehre, PhD, generated high-powered microscopic images showing startlingly high SARS-CoV-2 viral loads on human respiratory surfaces, ready to spread infection in infected individuals and transmit infection to others.
Facebook unveiled a new product today called Facebook Campus: “a college-only space designed to help students connect with fellow classmates over shared interests.”Sound familiar? Campus appears to be a throwback to the first days of Facebook, when a person had to have a college email address and attend a select group of universities to be able to join. Charmaine Hung, Campus’s product...
La Nina—which often means a busier Atlantic hurricane season, a drier Southwest and perhaps a more fire-prone California—has popped up in the Pacific Ocean.
NASA on Thursday announced it was in the market for Moon rocks, and wants to pay companies to scoop out the dirt, take a photo, and then have it ready for collection by a future mission.
People are starting almost all the wildfires that threaten U.S. homes, according to an innovative new analysis combining housing and wildfire data. Through activities like debris burning, equipment use and arson, humans were responsible for igniting 97% of home-threatening wildfires, a University of Colorado Boulder-led team reported this week in the journal Fire.
A novel process to fabricate special optical fiber that is far simpler, faster and cheaper than the conventional method has been developed by Cristiano Cordeiro, a researcher and professor at the University of Campinas's Physics Institute (IFGW-Unicamp) in the state of São Paulo, Brazil. Cordeiro created the innovation during a research internship at the University of Adelaide in Australia,...
The search is on to discover new states of matter, and possibly new ways of encoding, manipulating, and transporting information. One goal is to harness materials' quantum properties for communications that go beyond what's possible with conventional electronics. Topological insulators—materials that act mostly as insulators but carry electric current across their surface—provide some...
It is established that matter can transition between different phases when certain parameters, such as temperature, are changed. Although phase transitions are common (like water turning into ice in a freezer), the dynamics that govern these processes are highly complex and constitute a prominent problem in the field of nonequilibrium physics.
Vehicles powered by polymer electrolyte membrane fuel cells (PEMFCs) are energy-efficient and eco-friendly, but despite increasing public interest in PEMFC-powered transportation, current performance of materials that are used in fuel cells limits their widespread commercialization.
For quantum optical technologies to become more practical, there is a need for large-scale integration of quantum photonic circuits on chips.
Observations by the NASA/ESA Hubble Space Telescope and the European Southern Observatory's Very Large Telescope (VLT) in Chile have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy...
Aerosols are tiny solid or liquid particles suspended in the air. They influence the climate by absorbing or scattering sunlight and serving as cloud condensation nuclei. Moreover, they can impact human well-being through adverse health effects of fine particulate matter.
Russian military hackers responsible for cyberattacks against Democratic targets during the 2016 American election are now targeting over 200 organizations in the United States (including political parties, think tanks, and consultants serving both Democrats and Republicans), according to Microsoft, which is increasingly calling out Russian cyber espionage. In the final weeks before the...
Nigerien student Hachimou Abdou has had to catch a boat to classes since river water swamped his route to university in the capital Niamey - one of about 760,000 people hit by severe flooding in recent weeks in parts of West and Central Africa. Floods are common during the rainy season, but in recent years climate change, land degradation and poor urban planning have led to more frequent...
The year 2020 will be remembered for being a very trying year and western wildfires have just added to the year's woes. So far in 2020, California has experienced 7,606 fires and those fires have consumed 2.3 million acres. Washington and Oregon have also been hard hit by wildfires. Over 300,000 acres are reported to be burning. Four towns in Oregon have been mostly destroyed by the wildfire...
NASA's Terra satellite obtained visible imagery of Tropical Storm Rene is it continued moving north though the central North Atlantic Ocean. Rene appeared more organized on satellite imagery as wind shear eased.
NASA's Aqua satellite analyzed Tropical Storm Paulette in infrared imagery as it moved through the Central Atlantic Ocean. At NASA, the imagery was false-colored to show cloud-top temperature gradients and identify the locations of the strongest storms. The imagery also indicated Paulette was being affected by wind shear.
Jupiter's moons are hot.
Anthropogenic ammonia emissions and the water content matter more than dry particle composition for the acidity of atmospheric aerosols in populated regions.
Recent observations have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters.
