Ozone causes skin to emit tiny airborne particles
Air pollution is responsible for 7 million premature deaths around the world every year, according to the World Health Organization. That's roughly the same number of people who die from smoking or malnutrition. The damaging effects of air pollution.....»»
How eutrophication and climate change alter food webs in the Baltic Sea
Phytoplankton is the primary energy source for all marine ecosystems: These tiny plants floating in the seawater use photosynthesis to bind energy in the form of biomass, which is then passed on step by step in the marine food webs all the way to dif.....»»
New analysis reveals a tiny black hole repeatedly punching through a larger black hole"s disk of gas
At the heart of a far-off galaxy, a supermassive black hole appears to have had a case of the hiccups. Astronomers from MIT, Italy, the Czech Republic, and elsewhere have found that a previously quiet black hole, which sits at the center of a galaxy.....»»
Researchers identify new method to boost laser processing resolution
Focusing a tailored laser beam through transparent glass can create a tiny spot inside the material. Researchers at Tohoku University have reported on a way to use this small spot to improve laser material processing, boosting processing resolution......»»
Researchers demonstrate that forests trap airborne microplastics, acting as terrestrial sinks
A research group led by Japan Women's University finds that airborne microplastics adsorb to the epicuticular wax on the surface of forest canopy leaves, and that forests may act as terrestrial sinks for airborne microplastics......»»
New study reveals influencers of global biogenic volatile organic compound emission trends over the last 20 years
Biogenic volatile organic compounds (BVOCs) emitted by vegetation are important precursors of ozone and secondary organic aerosols in the atmosphere, affecting air quality, clouds, and climate. However, BVOC emissions remain highly uncertain because.....»»
Testing begins on sensitive neutrino detector for nonproliferation and fundamental physics
Neutrinos and antineutrinos are nearly massless particles produced in many nuclear reactions, including the fission of uranium in nuclear power plants on Earth and the fusion reactions at the core of the sun......»»
The Atari 400 Mini is a tiny system with big emulation potential
The Atari 400 Mini isn't just another tiny retro console. It's the perfect home for all your emulated 8-bit Atari games......»»
Scientists on the hunt for evidence of quantum gravity"s existence at the South Pole
Several thousand sensors distributed over a square kilometer near the South Pole are tasked with answering one of the large outstanding questions in physics: does quantum gravity exist? The sensors monitor neutrinos—particles with no electrical cha.....»»
Nevada"s first big-game moose hunt will be tiny as unusual southern expansion defies climate change
In what will be a tiny big-game hunt for some of the largest animals in North America, Nevada is planning its first-ever moose hunting season this fall......»»
Jon Stewart, still a "tiny, neurotic man," back to remind Americans what"s at stake
It's an uncomfortable truth: Jon Stewart and Donald Trump both tapped the same well of latent public disaffection with politics and the media in the 2000s. Trust in media and government had been declining for several decades. But the symbiotic relati.....»»
NASA"s tiny BurstCube mission launches to study cosmic blasts
NASA's BurstCube, a shoebox-sized satellite designed to study the universe's most powerful explosions, is on its way to the International Space Station......»»
Team proposes using AI to reconstruct particle paths leading to new physics
Particles colliding in accelerators produce numerous cascades of secondary particles. The electronics processing the signals avalanching in from the detectors then have a fraction of a second in which to assess whether an event is of sufficient inter.....»»
The Mars science helicopter could be an airborne geologist on Mars
After more than 70 successful flights, a broken rotor ended the remarkable and groundbreaking Ingenuity helicopter mission on Mars. Now, NASA is considering how a larger, more capable helicopter could be an airborne geologist on the Red Planet. For t.....»»
"Tiny, beautiful, and completely unknown animals": Citizen scientists discover new beetles from the Borneo forest
The undiscovered small beetles in the tropical rainforest are probably endless. But that did not discourage citizen scientists on expeditions to the Ulu Temburong forest in Borneo to keep adding them to scientific records, one at a time. Together wit.....»»
High-quality microwave signals generated from tiny photonic chip
In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact device—a chip so small, it could fit on a sharp pencil.....»»
Using polarization to improve quantum imaging
Quantum imaging is a growing field that takes advantage of the counterintuitive and "spooky" ability of light particles, or photons, to become linked, or entangled, under specialized circumstances. If the state of one photon in the entangled duo gets.....»»
Cleaning up environmental contaminants with quantum dot technology
The 2023 Nobel Prize in Chemistry was focused on quantum dots—objects so tiny, they're controlled by the strange and complex rules of quantum physics. Many quantum dots used in electronics are made from toxic substances, but their nontoxic counterp.....»»
Study finds large accumulations of plastics in the ocean, even outside so-called garbage patch
When plastic ends up in the ocean, it gradually weathers and disintegrates into small particles. If marine animals ingest these particles, their health can be severely affected. Large accumulations of plastic can therefore disrupt the biological bala.....»»
Nanoparticles target multiple COVID variants through the twist in the spike protein
Teardrop-shaped particles designed to inactivate multiple strains of the SARS-CoV-2 virus could one day complement existing treatments for COVID-19, according to a new study led by researchers at the University of Michigan and Jiangnan University in.....»»
Astrophysicist"s research could provide a hint in the search for dark matter
Dark matter is one of science's greatest mysteries. It doesn't absorb, reflect or emit light, so we can't see it. But its presence is implied by the gravitational effects it appears to have on galaxies......»»
