Researchers reveal sources of black carbon in southeastern Qinghai-Tibet plateau
Black carbon (BC) is the result of incomplete combustion of fossil fuels and biomass, with strong light absorption. It is second only to carbon dioxide as a climate-forcing factor for atmospheric warming. Deposition of BC on snow and ice surfaces red.....»»
Unraveling the mysteries of consecutive atmospheric river events
In California's 2022-2023 winter season, the state faced nine atmospheric rivers (ARs) that led to extreme flooding, landslides, and power outages—the longest duration of continuous AR conditions in the past 70 years. Scientists at Lawrence Berkele.....»»
Are Titan"s dunes made of comet dust?
A new theory suggests that Titan's majestic dune fields may have come from outer space. Researchers had always assumed that the sand making up Titan's dunes was locally made, through erosion or condensed from atmospheric hydrocarbons. But researchers.....»»
Researchers investigate three star-forming regions, identify hundreds young stellar objects
Using data from various space telescopes and astronomical surveys, Armenian researchers have investigated three star-forming regions. The study identified hundreds of young stellar objects and provided important information regarding the stellar cont.....»»
NASA"s Roman space telescope"s "eyes" pass first vision test
Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA's Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct.....»»
Atom-by-atom: Imaging structural transformations in 2D materials
Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity and magnetism.....»»
The Aral Sea has made Central Asia significantly dustier, according to study
The drying up of the Aral Sea has made Central Asia 7% dustier in the last 30 years. Between 1984 and 2015, dust emissions from the growing desert almost doubled from 14 to 27 million tons. This is the result of a study by the Leibniz Institute for T.....»»
Peptides on interstellar ice: Study finds presence of water molecules not a major obstacle for formation
A research team led by Dr. Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. However, it was previo.....»»
Huge database gives insight into salmon patterns at sea
A massive new analysis of high seas salmon surveys is enhancing the understanding of salmon ecology, adding details about where various species congregate in the North Pacific Ocean and their different temperature tolerances. The study is published i.....»»
Attosecond imaging made possible by short and powerful laser pulses
Extremely short pulses of laser light with a peak power of 6 terawatts (6 trillion watts)—roughly equivalent to the power produced by 6,000 nuclear power plants—have been realized by two RIKEN physicists. This achievement will help further develo.....»»
From tape measures to space lasers: Quantifying biomass of the world"s tallest forests
In this era of accelerating climate crisis, accounting for all aspects of Earth's carbon cycle is a crucial task. The magnitude of atmospheric carbon burden means trees and forests are limited but important instruments among a suite of mitigation opt.....»»
Discovery of organic catalyst could lead to cheaper fuel cells
With atmospheric carbon dioxide at record highs, the search for clean-energy alternatives to the use of fossil fuels is growing increasingly urgent......»»
A rechargeable nanotorch: Afterglow luminescence imaging tracks cell-based microrobots in real time
An afterglow luminescent nanoprobe opens up new possibilities for imaging living cells. As a research team reports in the journal Angewandte Chemie International Edition, their new "nanotorch" can continue to luminesce for more than 10 days after a s.....»»
Hubble spots a bright galaxy peering out from behind a dark nebula
A new image from the Hubble Space Telescope shows a galaxy partly hidden by a huge cloud of dust known as a dark nebula......»»
Iconic savanna mammals face genetic problems due to fences and roads
Whether by way of Attenborough, Disney or National Geographic, the iconic scene is familiar to many. The ground trembles and clouds of dust swirl as enormous hordes of large animals thunder across the African savanna, cross rivers en masse and are pi.....»»
Unraveling the song of ice and fire across the American landscape with machine learning
In the rugged terrain of the western United States, where wildfires rage unchecked, a surprising connection emerges with the tumultuous skies of the central US. A recent study published in Advances in Atmospheric Sciences explores the intriguing rela.....»»
Fallout 4 Next-Gen Update: Release Date & Details
