Analysis: States Can Lead Equitable Transition to 100% Renewable Energy by 2035

CAMBRIDGE, Massachusetts (April 19, 2022)—The need for resilient renewable energy is stronger than ever, as demand for clean electricity grows and worsening climate impacts challenge the aging power grid. Fortunately, states can show climate leadership and meet 100% of their electricity needs with renewable energy by 2035, according to “On the Road to 100% Renewables,” […]

Inspired by Prehistoric Creatures, NIST Researchers Make Record-Setting Lenses

Five hundred million years ago, the oceans teemed with trillions of trilobites — creatures that were distant cousins of horseshoe crabs.  All trilobites had a wide range of vision, thanks to compound eyes — single eyes composed of tens to thousands of tiny independent units, each with their own cornea, lens and light-sensitive cells. But […]

Flexible Quantum Sieve Made at TU Dresden Filters the Fuel of Starship Enterprise

Deuterium, the heavy brother of hydrogen, is considered a promising material of the future – because of its wide range of applications: in science, for energy generation, or in the production of pharmaceuticals. However, the extraction of deuterium from its natural isotope mixture has so far been complex and expensive. With a porous material developed […]

Undersea detector proves it’s swell – A first-of-its-kind cosmic ray sensor successfully observes tsunami waves

Highly energetic particles called muons are ever present in the atmosphere and pass through even massive objects with ease. Sensitive detectors installed along the Tokyo Bay tunnel measure muons passing through the sea above them. This allows for changes in the volume of water above the tunnel to be calculated. For the first time, this […]

Researchers detect the world’s first wild river otter coronavirus case

Researchers at the CEU Cardenal Herrera University (CEU UCH) in Valencia, the Institute of Biomedicine of Valencia (CSIC) and the Autonomous University of Barcelona have detected the first case of SARS-CoV-2 coronavirus in a European river otter in Spain. It is a specimen of Eurasian river otter (Lutra lutra), whose remains were found near a […]

ESO telescope captures surprising changes in Neptune’s temperatures

An international team of astronomers have used ground-based telescopes, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to track Neptune’s atmospheric temperatures over a 17-year period. They found a surprising drop in Neptune’s global temperatures followed by a dramatic warming at its south pole.“This change was unexpected,” says Michael Roman, a postdoctoral research associate […]

Researchers find humans have given wild animals their diseases nearly 100 times

A research team led by scientists at Georgetown University has found that humans give viruses back to animals more often than previously thought. In a study published in Ecology Letters, the authors describe nearly 100 different cases where diseases have undergone “spillback” from humans to wild animals, much like how SARS-CoV-2 has spread in mink farms, lions and […]

Crowdsourcing campaign identifies drivers of tropical forest loss

To combat forest loss in the tropics, a new study uses crowdsourcing to identify the drivers of deforestation. The resulting dataset can be used to create high-resolution maps and help policymakers apply the best protection measures. Every year, 10 million hectares of forest disappear worldwide, predominantly driven by human activities such as agriculture expansion, building […]

UC Santa Barbara geologists lead the effort to describe the devastating eruption in Tonga

On January 15, the volcano Hunga Tonga-Hunga Ha’apai devastated the nation of Tonga. The eruption triggered tsunamis as far afield as the Caribbean and generated atmospheric waves that travelled around the globe several times. Meanwhile, the volcano’s plume shot gas and ash through the stratosphere into the lower mesosphere. Just two months after the eruption, […]

Older wildfire smoke plumes can affect climate

Aerosols carried in wildfire smoke plumes that are hundreds of hours old can still affect climate, according to a study out of the University of California, Davis. The research, published in the journal Environmental Science and Technology, suggests that wildfire emissions even 10 days old can affect the properties of aerosols — suspended liquid or […]

Coronavirus may double severe complications in pregnancy

A Kaiser Permanente analysis of pregnant patients who tested positive for the coronavirus found more than double the risk of poor outcomes including preterm birth, venous thromboembolism (blood clot), and severe maternal morbidity, which includes conditions such as acute respiratory distress syndrome and sepsis. The study was published in JAMA Internal Medicine on March 21. An analysis […]

ExoMars suspended

As an intergovernmental organization mandated to develop and implement space programs in full respect with European values, we deeply deplore the human casualties and tragic consequences of the aggression towards Ukraine. While recognizing the impact on scientific exploration of space, ESA is fully aligned with the sanctions imposed on Russia by its Member States. ExoMars […]

Could the internet be driven by climate-friendly “natural intelligence”? Global network of solar-powered servers shows how

The energy requirements of the Internet, the devices and systems using it and the servers that support it are responsible for greenhouse gas emissions equal to that of the global airline industry, and this carbon cost is growing rapidly with the expansion of blockchain-enabled transactions: The carbon footprint of a single Ethereum transaction is equivalent to nearly 329,000 credit […]

There’s more to AI Bias than biased data, NIST report highlights

As a step toward improving our ability to identify and manage the harmful effects of bias in artificial intelligence (AI) systems, researchers at the National Institute of Standards and Technology (NIST) recommend widening the scope of where we look for the source of these biases — beyond the machine learning processes and data used to […]
