Scientists create black arsenic visible infrared photodetectors
In recent years, the exceptional structure and fascinating electrical and optical properties of two-dimensional (2D) layered crystals have attracted widespread attention. Examples of such crystals include graphene, black phosphorus (BP), and transiti.....»»
Scientists find ancient, endangered lamprey fish in Queensland, 1400 km north of its previous known range
The Australian brook lamprey (Mordacia praecox) is part of a group of primitive jawless fish. It's up to 15 cm long, with rows of sharp teeth. Surprisingly, it doesn't use these teeth to suck blood like most lamprey species—it's non-parasitic......»»
Researchers target spermidine production to combat emerging drug resistance in Salmonella
Food-borne diseases like typhoid, caused by Salmonella Typhimurium, are a severe threat to public health, especially in India. The indiscriminate use of antibiotics has allowed this bacterium to become resistant, posing a major hurdle in treating inf.....»»
"Lost" spy satellite orbited Earth undetected for 25 years—until now, scientists say
An experimental spy satellite that was deemed "lost" after eluding detection for decades has finally been found. "The S73-7 satellite has been rediscovered after being untracked for 25 years," astrophysicist Jonathan McDowell said in an April 29 post.....»»
Study reveals new mechanism to explain how continents stabilized
Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new mechanism proposed by Penn State scientists may explain ho.....»»
Model predicts future spread of box tree moth in North America
CABI scientists have led research with collaborations from the University of Toronto and University of Guelph, both in Canada, to update a model which predicts the future spread of the box tree moth (Cydalima perspectalis) in North America......»»
Study pinpoints cellular response to pressure in sea star embryos
An international team of scientists has discovered a new cellular mechanism that explains how cells can adapt to pressure changes during tissue growth by packing themselves into a unique shape......»»
MITRE breach details reveal attackers’ successes and failures
MITRE has shared a timeline of the recent breach if fell victim to and has confirmed that it began earlier than previously thought: on December 31, 2023. On that day, the attackers deployed a web shell on an external-facing Ivanti Connect Secure VPN.....»»
Study reveals flaw in long-accepted approximation used in water simulations
Computational scientists at the Department of Energy's Oak Ridge National Laboratory have published a study in the Journal of Chemical Theory and Computation that questions a long-accepted factor in simulating the molecular dynamics of water: the 2-f.....»»
Researchers reveal how molecular roadblocks slow the breakdown of cellulose for biofuels
Cellulose, which helps give plant cell walls their rigid structure, holds promise as a renewable raw material for biofuels—if researchers can accelerate the production process. Compared to the breakdown of other biofuel materials like corn, breakin.....»»
From fossils to fuel: Energy potential of Mozambique"s Maniamba Basin
In the ever-expanding search for energy resources, a new study has emerged from Mozambique's Maniamba Basin. A team led by Nelson Nhamutole, a Ph.D. student at the University of the Witwatersrand, and his team of scientists from around the world, sha.....»»
Global meta-analysis quantifies benefits of cover crop use
For years, both scientists and farmers have debated whether the use of cover crops—plants used to cover the ground after harvesting of main crops—have a positive or negative impact on subsequent crop yield. Hundreds of studies have been performed.....»»
Engineers develop innovative microbiome analysis software tools
Since the first microbial genome was sequenced in 1995, scientists have reconstructed the genomic makeup of hundreds of thousands of microorganisms and have even devised methods to take a census of bacterial communities on the skin, in the gut, or in.....»»
Geologists reveal mysterious and diverse volcanism in lunar Apollo Basin, Chang"e-6 landing site
The far side of the moon is a mysterious place that is never visible from the Earth. The most remarkable feature of the moon is its asymmetry between the lunar near side and far side in composition, crust thickness, and mare volcanism. Scientists hav.....»»
How NASA"s Roman mission will hunt for primordial black holes
Astronomers have discovered black holes ranging from a few times the sun's mass to tens of billions. Now a group of scientists has predicted that NASA's Nancy Grace Roman Space Telescope could find a class of "featherweight" black holes that has so f.....»»
Advanced experimental setup expands the hunt for hidden dark matter particles
Scientific evidence for dark matter comes from observing how it influences the motion of stars and galaxies. Scientists believe that dark matter may consist of particles. To search for these particles and their billiard ball-like collisions, research.....»»
Discovery of structural specialization in myriapod ovaries
Elaborate observations reveal the structural specialization within an epithelial layer covering oocytes in the Japanese pill-millipede, Hyleoglomeris japonica, considered absent in Myriapoda. Comparing this result with previous descriptions suggested.....»»
Number of religious "nones" has soared, but not number of atheists—social scientists want to know why
The number of individuals in the United States who do not identify as being part of any religion has grown dramatically in recent years, and "the nones" are now larger than any single religious group. According to the General Social Survey, religious.....»»
Materials scientists reveal pathway for designing optical materials with specialized properties
While we usually think of disorder as a bad thing, a team of materials science researchers led by Rohan Mishra, from Washington University in St. Louis, and Jayakanth Ravichandran, from the University of Southern California, have revealed that—when.....»»
Microbiome studies help explore treatments for genetic disorders
