Decoy particles trick coronavirus as it evolves
They might look like cells and act like cells. But a new potential COVID-19 treatment is actually a cleverly disguised trickster, which attracts viruses and binds them, rendering them inactive......»»
Treat or Trick? Astronomical Objects Are Beautiful—And Creepy
If you’ve ever seen faces in clouds, these heavenly entities will leave you haunted.....»»
Black Basta operators phish employees via Microsoft Teams
Black Basta ransomware affiliates are still trying to trick enterprise employees into installing remote access tool by posing as help desk workers, now also via Microsoft Teams. Phishing via MS Teams Earlier this year, Rapid7 warned about Black Basta.....»»
For heating plasma in fusion devices, researchers unravel how electrons respond to neutral beam injection
Heating a plasma for fusion research requires megawatts of power. One approach that research tokamaks use to achieve the necessary power input is neutral beam injection (NBI). With NBI, fast neutral particles are generated in a device called a beam s.....»»
Search results for dark photon leptonic decays manage to exclude new regions
Dark photons are hypothetical particles that resemble light particles (i.e., photons), but interact weakly with normal matter, which would make them impossible or very difficult to detect using conventional experimental methods. These particles are d.....»»
Synthesis method improves catalytic activity by controlling the surface structure of metal particles
Fine-tuning the reactions that produce hydrogen (H2) for use as a clean fuel is an important endeavor to fight against climate change. Researchers at Tohoku University and the Tokyo University of Science have succeeded in improving the catalytic acti.....»»
Tiny airborne particles within air pollution could be a silent killer
Long-term high ultrafine particle concentrations in New York state neighborhoods are linked to higher numbers of deaths. That is the key finding of our new research, published in the Journal of Hazardous Materials......»»
Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»
The Physics Trick That Makes These New Super Cars So Insanely Fast
Zero to 60 in 1.4 seconds? By lowering air pressure under the car, automakers can dial the acceleration way up......»»
Physicists show that neutron stars may be shrouded in clouds of axions
A team of physicists from the universities of Amsterdam, Princeton and Oxford have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter.....»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
New benchmark helps solve the hardest quantum problems
From subatomic particles to complex molecules, quantum systems hold the key to understanding how the universe works. But there's a catch: when you try to model these systems, that complexity quickly spirals out of control—just imagine trying to pre.....»»
A look into cloudy liquids: New method makes the expansion of turbid drops in water visible
When driving though a bank of fog, car headlights are only of limited help as the light is scattered by the water particles suspended in the air. The situation is similar when you try to observe the inside of a drop of milk in water or the internal s.....»»
Study suggests dolphins could be exposed to potentially harmful microplastics through inhalation
U.S. researchers have detected microplastic particles in air exhaled by wild bottlenose dolphins, suggesting that inhalation may be a relevant route of exposure to these potentially harmful contaminants. Miranda Dziobak of the College of Charleston i.....»»
First coherent picture of an atomic nucleus made of quarks and gluons
The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of atomic nuclei hitherto observ.....»»
A quantum material could be the future of high-energy X-ray imaging and particle detection
Scintillators are detectors that make high-energy X-rays or particles visible through flashes of light to form an image. Their many applications include particle physics, medical imaging, X-ray security and more......»»
Is COVID-19 infecting wild animals? Researcher test species from bats to seals to find out
Over the course of the COVID-19 pandemic, researchers have found coronavirus infections in pet cats and dogs and in multiple zoo animals, including big cats and gorillas. These infections have even happened when staff were using personal protective e.....»»
Solid-state batteries need proven benefits over lithium ion to become EV market player
As solid-state battery technology evolves, lithium ion batteries, which power the vast majority of EVs on the road, are also advancing......»»
Best practices for implementing threat exposure management, reducing cyber risk exposure
In this Help Net Security interview, Sanaz Yashar, CEO at Zafran, discusses the role of threat exposure management (TEM) in modern cybersecurity strategies. As traditional vulnerability management evolves, TEM addresses the overwhelming risks arising.....»»
Engineers create a chip-based tractor beam for biological particles
MIT researchers have developed a miniature, chip-based "tractor beam," like the one that captures the Millennium Falcon in the film "Star Wars," that could someday help biologists and clinicians study DNA, classify cells, and investigate the mechanis.....»»
Surprising amount and variety of gamma radiation is produced in large tropical thunderstorms, observations reveal
In the 1990s, NASA satellites built to spot high-energy particles coming from supernovas and other celestial-sized objects discovered a surprise—high energy gamma radiation bursts coming from right here on Earth......»»
