Better understanding air pollution mechanisms
Earth's atmosphere has a budget, and when expenses outpace savings, secondary aerosols form in areas of excessive pollution. Greenhouse gases enter the atmosphere, and free radicals bond to the molecules, rendering them inert. But when there are more.....»»

Chinese fruit fly genomes reveal global migrations, repeated evolution
Fruit flies (Drosophila melanogaster), which humans have inadvertently spread around the globe, arrived in China roughly 4,000 years ago, according to a new population genomics study that adds to our understanding of the insect's global migration, de.....»»
Nitrogen pollution is less harmful to mixed forests, study shows
In a study published in the journal Plant and Soil, researchers from the Institute of Applied Ecology of the Chinese Academy of Sciences have shown that mixed larch and deciduous forests are more resistant to soil acidification—a decrease in soil p.....»»

MITRE released EMB3D, a cybersecurity threat model for embedded devices. The model provides a cultivated knowledge base of cyber threats to embedded devices, providing a common understanding of these threats with the security mechanisms required to m.....»»
Study finds consistent decline in nitrogen oxides emissions from human activities in China since 2020
Nitrogen oxides (NOx) form aerosols and ozone in the atmosphere and are significant contributors to air pollution and climate change. China is the largest emitter, yet accurate and timely information on NOx emissions in China has been lacking since 2.....»»
New "forever chemical" cleanup strategy discovered
As the U.S. Environmental Protection Agency cracks down on insidious "forever chemical" pollution in the environment, military and commercial aviation officials are seeking ways to clean up such pollution from decades of use of fire suppressant foams.....»»
Team develops an epigenome editing toolkit to dissect the mechanisms of gene regulation
Understanding how genes are regulated at the molecular level is a central challenge in modern biology. This complex mechanism is mainly driven by the interaction between proteins called transcription factors, DNA regulatory regions, and epigenetic mo.....»»
Marine bacteria team up to produce a vital vitamin
A German-American research team led by microbiologist Dr. Gerrit Wienhausen from the University of Oldenburg (Germany) has come an important step closer to a better understanding of highly complex interactions between marine microorganisms. The resea.....»»
Proton-lithium interactions model lays the foundation for unlocking the secrets of stellar reactions
The reactions between protons and lithium isotopes, especially lithium-6, are pivotal for several domains ranging from nuclear energy applications to astrophysics. The detailed understanding of these interactions aids in improving models for neutron.....»»
How conservationists brought Melbourne"s Merri Creek back from pollution, neglect and weeds
I met with a friend for a walk beside Merri Creek, in inner Melbourne. She had lived in the area for a few years, and as we walked beside the creek, past trees, native grasses, a small wetland echoing with frog calls, I talked about how it had looked.....»»
Study reveals differences in DNA folding between neurons and other brain cells, links them to cell functions
Researchers from Skoltech and their colleagues have investigated nerve cell regulation. Mounting knowledge of regulation mechanisms could enable a better understanding of how the healthy brain operates and what goes wrong in developmental and oncolog.....»»
Study sheds light on cancer cell "tug-of-war"
Understanding how cancerous cells spread from a primary tumor is important for any number of reasons, including determining the aggressiveness of the disease itself. The movement of cells into the extracellular matrix (ECM) of neighboring tissue is a.....»»
Fruit fly model identifies key regulators behind organ development
A new computational model simulating fruit fly wing development has enabled researchers to identify previously hidden mechanisms behind organ generation......»»
Laboratory and natural strains of intestinal bacterium turn out to have similar mutational profiles
Understanding mutational processes in a cell offers clues to the evolution of a genome. Most actively, mutation processes are studied in human cancer cells, while other genomes are often neglected......»»
