Neutral particles a drag on disruptive plasma blobs
For decades, scientists have been working to harness clean, renewable fusion energy, which occurs naturally in stars like our sun. Using strong magnetic fields to confine hot plasmas within a donut-shaped device called a tokamak, researchers can gene.....»»
Quantum ‘Ghost Imaging’ Reveals the Dark Side of Plants
Entanglement lets researchers watch plants in action without disruptive visible light.....»»
Nuclear theorists turn to supercomputers to map out matter"s building blocks in 3D
Deep inside what we perceive as solid matter, the landscape is anything but stationary. The interior of the building blocks of the atom's nucleus—particles called hadrons that a high school student would recognize as protons and neutrons—are made.....»»
Black hole pairs may unveil new particles
In a paper published in Physical Review Letters this week, physicists from Amsterdam and Copenhagen argue that close observations of merging black hole pairs may unveil information about potential new particles. The research combines several new disc.....»»
Modified nano-sized cell particles found to boost cancer immunotherapy, reduce side effects
Immunotherapy is a type of cancer treatment that uses the body's own immune system to help fight cancer. This is by stimulating the immune response to recognize and attack cancer cells more effectively. The treatment involves using substances that bo.....»»
Antarctic research finds exceptional warm air intrusions and omnipresent aerosol layers in the stratosphere
Extremely clean air on the ground, warm air intrusions and sulfate aerosol at high altitudes—a Leipzig research project has gained new insights into clouds in Antarctica. From January to December 2023, the vertical distribution of aerosol particles.....»»
Toyota has repair for Grand Highlander, Lexus TX after lengthy stop-sale
A costly and disruptive stop-sale to Toyota's large three-row crossovers is expected to end in late October after Toyota determined that modified side-curtain airbags will bring the vehicles back into compliance......»»
Scientists cool positronium to near absolute zero for antimatter research
Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons. Positronium is an exotic atom composed of a single negative electron and a positively charged antimatter positron. It is naturally very short-live.....»»
Study finds tire abrasion particles threaten fresh water habitats
A research team led by Prof. Dr. Markus Pfenninger from the Senckenberg Biodiversity and Climate Research Center Frankfurt (SBiK-F) has investigated the effects of tire-abrasion particles on freshwater ecosystems......»»
Fluctuating hydrodynamics theory could describe chaotic many-body systems, study suggests
Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to the world of quantum physics?.....»»
New mass spectrometry technology could transform tiny sample analysis
Mass spectrometry is a powerful technique that allows scientists to break down and identify the building blocks of just about anything by measuring the mass of the tiny particles of which something is comprised. It has a major limitation, however—a.....»»
Greenpeace sounds alarm on microplastics ingested by Hong Kong wildlife
Microplastic particles turned up in the vast majority of waste samples taken from Hong Kong wildlife in a Greenpeace study, the group said Monday, suggesting that animals still ingest plastics even if they are not feeding in urban areas......»»
Neutral news sources could exploit today"s polarized mediascape to boost revenue—why they may choose not to
Even news outlets perceived as politically neutral can benefit from today's polarized media environment......»»
Neutral atom innovations by quantum systems accelerator mark quantum computing milestones
Before quantum computers can solve complex problems, researchers must develop technologies that manage larger numbers of qubits (the building blocks of quantum computers) for extended periods. Neutral atoms play an important role in this effort and a.....»»
Physicists capture images of atoms flowing along a boundary without resistance despite obstacles in their path
Typically, electrons are free agents that can move through most metals in any direction. When they encounter an obstacle, the charged particles experience friction and scatter randomly like colliding billiard balls......»»
Decoding the language of cells with the power of proteomics
Hundreds of millions of years ago, single cells joined forces to become multicellular organisms. At the foundation of this multicellular world is the cell surface: the plasma membrane surrounding each cell, where individual units meet and communicate.....»»
Composite plastic degrades easily with bacteria, offers environmental benefits
Billions of tons of plastic waste clutter our world. Most of it has accumulated on the ground and in the oceans or disintegrated into tiny particles known as microplastics that pollute the air and the water, penetrating vegetation and the bloodstream.....»»
Scientists uncover hidden source of snow melt: Dark brown carbon
Wildfires leave potent climate heaters behind in their wake, particles that enhance the absorption of sunlight and warm the atmosphere. Dropped on snow like a wool poncho, these aerosols darken and decrease the surface reflectance of snowy places......»»
The world"s fastest single-shot 2D imaging technique films ultrafast dynamics in flames
Candle flames and airplane engines produce tiny soot particles from polycyclic aromatic hydrocarbons (PAHs) as their precursors, both of which are harmful to humans and the environment. These carbon-based particles are also common in space, making up.....»»
Observatory reveals key evidence of cosmic ray acceleration limit in W51 for first time
The Large High Altitude Air Shower Observatory (LHAASO) officially released the precise measurements of high-energy gamma radiation from the W51 complex, confirming it as a cosmic-ray accelerator boosting particles up to so-called ultra-high energies.....»»
Nanoplastics put stress on trees and impair photosynthesis
It is well known that more and more plastic waste is ending up in soil and bodies of water. Researchers are particularly concerned about tiny micro- and nano-sized particles. It remains unclear how and to what extent they are able to enter living org.....»»
