Paradox of extreme cold events in a warming world
According to Copernicus Climate Change Service, February 2024 was the warmest February ever recorded globally. However, North America, Asia, and parts of Europe experienced record-breaking cold temperatures. In some places, such as China’s Mohe and Russia’s Yakutsk, temperatures dipped to the life-threatening lowest levels. Alarmingly, this juxtaposition of increasing temperatures amidst extreme…

Substantial global cost of climate inaction
Traditionally, estimates of how climate change will affect global economies have focused on the effects of annual temperature changes. However, the additional impacts of variability and extremes in rainfall and temperature have remained largely unexplored, until now. Using projections from 33 global climate models, an international research team, led by Paul Waidelich at ETH Zurich, conducted a…

Workings of working memory detailed
Cedars-Sinai investigators have discovered how brain cells responsible for working memory — the type required to remember a phone number long enough to dial it — coordinate intentional focus and short-term storage of information.
The study detailing their discovery was published in the peer-reviewed journal Nature.
“We have identified for the first time a group of neurons, influenced by two…

Understanding climate warming impacts on carbon release from the tundra
The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon sinks into a carbon source, exacerbating the effects of climate change.
A team of over 70 scientists from different countries used so called open-top chambers (OTCs) to experimentally simulate the…

Sony FE 16-25mm F2.8 G sample gallery
The Sony FE 16-25mm F2.8 G is a relatively compact wide-angle zoom E-mount lens aimed at street and travel photographers.
We were able to get our hands on the lens for a day and figured most readers would be curious to see some street and architectural photography out of this lens, so we hit the streets of downtown Seattle and ducked into the Seattle Public library when the weather turned…

Plastic pollution can kill variety of ocean embryos
High levels of plastic pollution can kill the embryos of a wide range of ocean animals, new research shows.
Scientists tested the effects of new PVC pellets (pre-production “nurdles” used to make many plastic products) on the development of seven species, spanning all major groups (superphyla) of ocean animals.
Exposure to high concentrations of PVC pellets prevented healthy development in all…

Blinken tells Jewish leaders in the US does not want Israel to ‘escalate’ after Iran attack
WASHINGTON (JTA) — The Biden administration does not want tensions between Iran and Israel to “escalate” after Iran’s massive attack on Israel over the weekend, US Secretary of State Antony Blinken told American Jewish leaders.
Blinken called the meeting at the State Department on Tuesday morning as Israel contemplates how and when to retaliate against Iran. Blinken underscored how eager the…

Pyrite, also known as fool's gold, may contain valuable lithium, a key element for green energy
There’s a reason airlines won’t let you put your laptop in your checked luggage; the lithium-ion battery poses a serious fire hazard. But why? Lithium is incredibly reactive. For instance, pure lithium violently interacts with seemingly innocuous water, releasing heat and forming highly flammable hydrogen. This reactivity, however, is exactly why lithium makes a great material for batteries, and…

Most massive stellar black hole in our galaxy found
Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency’s Gaia mission because it imposes an odd ‘wobbling’ motion on the companion star orbiting it. Data from the European Southern Observatory’s Very Large Telescope (ESO’s VLT) and other ground-based observatories were used to…

The joy of sports: How watching sports can boost well-being
For many individuals, sports have long served as a source of enjoyment and relaxation. Watching sports, particularly at large gatherings, goes beyond entertainment. It fosters a sense of community and belonging among audiences. This sense of connection not only makes individuals feel good but also benefits society by improving health, enhancing productivity, and reducing crime. Although it is…

Newly sequenced genome reveals coffee's prehistoric origin story -- and its future under climate change
The key to growing coffee plants that can better resist climate change in the decades to come may lie in the ancient past.
Researchers co-led by the University at Buffalo have created what they say is the highest quality reference genome to date of the world’s most popular coffee species, Arabica, unearthing secrets about its lineage that span millennia and continents.
Their findings, published…

Can animals count?
Research co-led by neuroscientists Professor Yung Wing-ho from City University of Hong Kong (CityUHK) and Professor Ke Ya from The Chinese University of Hong Kong (CUHK) Faculty of Medicine (CU Medicine) has made a groundbreaking discovery regarding number sense in animals by confirming the existence of discrete number sense in rats, offering a crucial animal model for investigating the neural…

A single atom layer of gold: Researchers create goldene
For the first time, scientists have managed to create sheets of gold only a single atom layer thick. The material has been termed goldene. According to researchers from Linköping University, Sweden, this has given the gold new properties that can make it suitable for use in applications such as carbon dioxide conversion, hydrogen production, and production of value-added chemicals. Their findings…

Tropical forests can't recover naturally without fruit-eating birds
New research from the Crowther Lab at ETH Zurich illustrates a critical barrier to natural regeneration of tropical forests. Their models — from ground-based data gathered in the Atlantic Forest of Brazil — show that when wild tropical birds move freely across forest landscapes, they can increase the carbon storage of regenerating tropical forests by up to 38 percent.
Birds seed carbon…

Physical activity reduces stress-related brain activity to lower cardiovascular disease risk
New research indicates that physical activity lowers cardiovascular disease risk in part by reducing stress-related signaling in the brain.
In the study, which was led by investigators at Massachusetts General Hospital (MGH), a founding member of the Mass General Brigham healthcare system and published in the Journal of the American College of Cardiology, people with stress-related conditions…

Switch to green wastewater infrastructure could reduce emissions and provide huge savings according to new research
University researchers have shown that a transition to green wastewater-treatment approaches in the U.S. that leverages the potential of carbon-financing could save a staggering $15.6 billion and just under 30 million tonnes of CO2-equivalent emissions over 40 years.
The comprehensive findings from Colorado State University were highlighted in Nature Communications Earth and Environment in a…

Evolution's recipe book: How 'copy paste' errors cooked up the animal kingdom
A series of whole genome and gene duplication events that go back hundreds of millions of years have laid the foundations for tissue-specific gene expression, according to a new study in the journal Nature Ecology and Evolution. The ‘copy paste’ errors allowed animals to keep one copy of their genome or genes for fundamental functions, while the second copy could be used as raw material for…
