A team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a high-sensitivity differential Helmholtz photoacoustic cell and successfully applied it to methane detection......»»
Restricting cars in cities: A cost-benefit analysis of Low Emission Zones
Faced with unmanageable traffic and health-threatening air quality, hundreds of cities across Europe are adopting measures to reduce the number of vehicles clogging their streets, with the aim of lowering air pollution levels and improving the qualit.....»»
New greenhouse gas projections show Colorado moving in right direction to reduce pollution
Colorado is projected to fall short of its benchmarks for reducing greenhouse gas emissions in the next five years, but a new look at progress shows that, like a person trying to lose weight for a class reunion, the state has shaved off a few more po.....»»
Mitochondrial study offers new insights into how our cells process RNA for energy production
Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have made a major discovery in how human cells produce energy. Their study, published in The EMBO Journal, reveals the detailed mechanisms of how mitochondria process.....»»
Plastics pollution worsens the impacts of all planetary boundaries, new study says
Plastics are not as safe and inert as previously thought. A new research study written by an international team of researchers uses the planetary boundaries framework to structure the rapidly mounting evidence of the effects of plastics on the enviro.....»»
Researcher highlights the combined effects of climate change and chemical pollution
Traditionally, research has focused on either climate change or chemical pollution in isolation, overlooking their combined effects. This oversight creates a blind spot in understanding the full scope of risks to ecosystems and human health......»»
Locally optimized urban form can reduce carbon dioxide emissions
Research suggests that urban areas could reduce their carbon dioxide (CO2) emissions by optimizing their urban form. However, the relationship between urban form and emissions is highly context-dependent and generalizations cannot be made......»»
Balancing quantity and quality: How X/Twitter"s algorithm influences our consumption of news
Are we only seeing the kind of news we want to see on social media? What effects do personalized algorithms have on our perception of news quality? Do algorithms help us serendipitously encounter information that we didn't expect? These are the quest.....»»
Public pressure found to influence whether companies reduce their environmental impact
The effectiveness of national voluntary programs asking companies to pledge to lower their pollution and greenhouse gas emissions depends on pressure from the public, according to a new study led by a Penn State researcher......»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Researcher: Beefing up Border Patrol is a bipartisan goal, but the agency has a troubled history
With U.S. voters across the political spectrum strongly concerned about border security, presidential candidates Kamala Harris and Donald Trump have been trying to one-up each other on who can reduce migration at the nation's southern border fastest.....»»
How project governance helps navigate public-private "coopetition" tensions
The Ariane 6 project, Europe's new space launcher, is in the headlines as the European Space Agency (ESA) and ArianeGroup push for its first launch in 2024. This high-profile initiative has faced delays, but it remains a cornerstone of European ambit.....»»
Helping the most vulnerable stay cool in extreme heat
The health effects of heat waves hit some communities harder than others. People with preexisting health conditions, as well as those who have low income or are physically or socially isolated, very old or very young, from racial or ethnic minority g.....»»
Defibrillation devices can still save lives using 1,000 times less electricity, optimized model finds
In a paper published in Chaos, researchers from Sergio Arboleda University in Bogotá, Colombia, and the Georgia Institute of Technology in Atlanta used an electrophysiological computer model of the heart's electrical circuits to examine the effect o.....»»
Space Innovation Lab experiment heads to International Space Station
The first human tissue samples from Oxford's Space Innovation Lab (SIL) have been launched and are on their way to the International Space Station, where they will be used to study the effects of space microgravity on the human aging process......»»
Mini-transmitters show infections with parasites affect local flight behavior of swallows
Swallows infected with parasites move less and in smaller ranges than healthy ones—with detrimental effects on their foraging success and their survival. As a result, infected individuals foraged in less productive areas, such as cultivated farmlan.....»»
Spraying rice with zinc oxide nanoparticles protects yields during heat waves, study finds
A small team of horticulturists in China and the U.S. has found that spraying rice plants with a zinc oxide nanoparticle solution helps them better handle the stress of a heat wave. In their study, published in Proceedings of the National Academy of.....»»
Researchers uncover focal adhesions as subcellular signaling hubs in PI3K-AKT pathway
The phosphatidylinositol 3-kinase (PI3K)-AKT signaling pathway is one of the most critical and extensively investigated signaling pathways. It is the central regulator of various cellular processes including cell growth, proliferation, metabolism, an.....»»
Small reductions to meat production in wealthier countries may help fight climate change
Scientists and environmental activists have consistently called for drastic reductions in meat production as a way to reduce emissions and, in doing so, combat climate change. However, a new analysis concludes that a smaller reduction, borne by wealt.....»»
Not the usual suspects: Research reveals novel genetic basis of pest resistance to biotech crops
If left unchecked, insect pests can devastate crops. To minimize damage and reduce the need for insecticide sprays, crops have been genetically engineered to produce bacterial proteins that kill key pests but are not harmful to people or wildlife. Ho.....»»
Beta cells: New insights into the structure, interactions and neuronal networking of primary cilia
Dysfunctions of the tiny cell processes (primary cilia) of the pancreatic beta cells could be a cause of type 2 diabetes. Little is known about the structure and function of these cilia. An international research team led by DZD researchers from the.....»»
