How mechanical ventilation affects the trajectories of aerosols that may carry viral particles
We have known for a longtime now that the COVID-19 virus, SARS-CoV-2 is a mostly airborne disease. Ventilation of indoor spaces is therefore one of the most useful ways in which we can keep people safe. Research in the International Journal of Simula.....»»
Breathing may introduce microplastics to the brain—new study
Small plastic particles are everywhere: in the soil where our food is grown, in the water we drink and in the air we breathe. They got there from the plastic we throw away, which ends up in landfill sites, rivers and seas. There the plastic waste slo.....»»
Lunar dust dynamics: Unveiling the charging properties and particle behavior of Chang"e-5 samples in an electric field
A study published in Engineering has shed new light on the behavior of lunar regolith particles under the influence of an external electric field, a discovery that could revolutionize space exploration and lunar resource utilization. The research, co.....»»
How climate change affects deer—experts draw findings from 20 years of research
Temperature, rainfall, snow and extreme weather events are all factors linked to climate change that directly affect wildlife. Understanding the impact of these factors on the physiology, population dynamics and distribution of different deer species.....»»
IBM opens its quantum-computing stack to third parties
You don't have to use IBM's tools to run software on its quantum processor. Enlarge / The small quantum processor (center) surrounded by cables that carry microwave signals to it, and the refrigeration hardware. (credit: IBM).....»»
New approach reveals details about aerosol properties from hard-to-sample areas in the atmosphere
The spatial distribution of ambient aerosol particles plays a huge role in aerosol–radiation–cloud interactions; however, not enough sampling has been done from the atmospheric boundary layer and lower free troposphere. This leaves large gaps in.....»»
Study suggests moon may have been captured from space rather than formed from collision particles
Over six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on Earth: calcium-rich, basalti.....»»
Turbulent solar wind originates in the sun"s corona, study shows
Solar wind is a never-ending stream of charged particles coming from the sun. Rather than a constant breeze, this wind is rather gusty. As solar wind particles travel through space, they interact with the sun's variable magnetic field, creating chaot.....»»
Historical racism still negatively affects the way paintings of Black people are perceived, research finds
There is little doubt that historical racism has influenced the content and composition of several famous figurative paintings. In March 2024, this could be seen in the debate around the exhibition of the Rex Whistler mural, The Expedition in Pursuit.....»»
Cryo-ET study provides viral close-up of HTLV-1, the "overlooked cousin of HIV"
In collaboration with the University of Minnesota and Cornell University, Martin Obr and Florian Schur from the Institute of Science and Technology Austria (ISTA) provide new details into the architecture of HTLV-1 (Human T-cell Leukemia Virus Type 1.....»»
War affects girls and boys differently, Democratic Republic of Congo study finds
War has become a regular part of life for many children. Millions are victims and witnesses to the horrors of war. Recent estimates by researchers at the Peace Research Institute Oslo show that one in six children globally lives in a conflict zone, a.....»»
Study finds good nutrition boosts honey bee resilience against pesticides, viruses
In a new study, researchers at the University of Illinois Urbana-Champaign tackled a thorny problem: How do nutritional stress, viral infections and exposure to pesticides together influence honey bee survival? By looking at all three stressors toget.....»»
Quantum sensing approach captures nanoscale electrochemical evolution in battery
Battery performance is heavily influenced by the non-uniformity and failure of individual electrode particles. Understanding the reaction mechanisms and failure modes at nanoscale level is key to advancing battery technologies and extending their lif.....»»
iPhone 16 Pro users experiencing touchscreen issues, some taps and swipes ignored
An increasing number of iPhone 16 Pro owners are reporting intermittent issues with their phone’s touchscreen responsiveness. Users experience taps and swipes seemingly being ignored, which affects various interactions like scrolling, pressing butt.....»»
Scientists reviewed 7,000 studies on microplastics. Their alarming conclusion puts humanity on notice
It's been 20 years since a paper in the journal Science showed the environmental accumulation of tiny plastic fragments and fibers. It named the particles "microplastics.".....»»
Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
Moral Judgments May Shift with the Seasons
Certain values carry more weight in spring and autumn than in summer and winter.....»»
Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
First-of-its kind tool allows scientists to manipulate cells without touching them
When studying the spread of cancer or the behavior of a virus like the one that causes COVID-19, the irony is that working with these harmful pathogens requires gentleness. Especially in the case of COVID, the particles do not survive well when makin.....»»
The memory in seeds: How plants carry environmental clues across generations
Phenotypic plasticity enables plants to adjust their physical traits in response to environmental variations, playing a vital role in their survival and adaptability. While past research has primarily focused on how these traits manifest within a sin.....»»
New testing system uses Janus particles to rapidly and accurately detect COVID-19
The importance of testing for diseases was thrust into the limelight during the COVID-19 pandemic. Many of us have undergone a PCR (Polymerase Chain Reaction) or ELISA (Enzyme-Linked Immunosorbent Assay) test within the past four years......»»
