NSF hopes big data will finger grantees not reporting foreign support

The National Science Foundation (NSF) will soon begin crunching several large databases to see whether there are scientists who failed to disclose ties to foreign institutions in their grant applications. It is arguably the boldest of several steps federal research agencies are taking to comply with a new law that aims to boost U.S. technological innovation–and prevent...

Exploring Jupiter's moon, Europa, possible with silicon-germanium transistor technology

Europa is more than just one of Jupiter's many moons -- it's also one of most promising places in the solar system to look for extraterrestrial life. Under 10 kilometers of ice is a liquid water ocean that could sustain life. But with surface temperatures at -180 Celsius and with extreme levels of radiation, it's also one of the most inhospitable places in the solar system. Exploring Europa could...

Slave traders’ names are still stamped on native plants. It’s time to ‘decolonise’ Australia’s public gardens | Brett Summerell

For too long we’ve dismissed Indigenous knowledge of the natural world. At Sydney’s botanic garden, signage is starting to reflect Aboriginal namesLike all botanic gardens, the Royal Botanic Garden Sydney is a classic artefact of the activities that took place during the colonisation of Australia in the 18th and 19th century.It was established to create a patch of landscape that mirrored those...

Why Atlantic Hurricanes Are Getting Stronger Faster Than Other Storms

Hurricane Ian, which peaked as a Category 4 storm in the Gulf of Mexico, hammered Southwest Florida this week, flooding the coastal areas around Fort Myers, leaving millions of people without power, and causing an unknown number of deaths. Ian lost some of its intensity as it crossed the state, but began regaining strength over the Atlantic, before veering back inland to slam Georgia and the...

Most Twitter users don't follow political elites, researchers suggest

While social media platforms are the primary source of political information for a growing number of people, a majority of Twitter users do not follow either members of Congress, their president or news media, a new study suggests. They are much more likely to follow Tom Hanks or Katie Perry than an elected official.

New tech could provide cheaper, less-polluting way to refine crude oil

Despite efforts to pivot toward renewable sources of energy, oil remains the backbone of modern society. It provides fuels for heat and transportation, and chemicals for everything from plastics to pharmaceuticals. But all these uses require separating crude oil into its various components. That separation process—which traditionally relies on heat—takes a tremendous amount of energy...

Webb, Hubble capture detailed views of DART impact

Two of NASA's Great Observatories, the James Webb Space Telescope and the Hubble Space Telescope, have captured views of a unique NASA experiment designed to intentionally smash a spacecraft into a small asteroid in the world's first-ever in-space test for planetary defense. These observations of NASA's Double Asteroid Redirection Test (DART) impact mark the first time that Webb and Hubble...

The road to future AI is paved with trust

The place of artificial intelligence, AI, in our everyday life is increasing and many researchers believe that what we have seen so far is only the beginning. However, AI must be trustworthy in all situations. A new project has drawn up a research-based roadmap intended to guide research funding bodies and decision-makers towards the trustworthy AI of the future.

SuperAger brains contain 'super neurons'

Neurons in an area of the brain responsible for memory were significantly larger in SuperAgers compared to cognitively average peers, individuals with early-stage Alzheimer's disease and even individuals 20 to 30 years younger than SuperAgers -- who are aged 80 years and older, reports a new study. The study of was the first to show that these individuals carry a unique biological signature that...

Researchers unveil mystery inside lithium oxygen batteries

With a high energy density, Li-O2 batteries have become a state-of-the-art battery technology. Inside the Li-O2 battery, the generation and disintegration of the discharged product solid lithium peroxide (Li2O2) have a significant effect on the battery's performance. Previous research has shed little light on Li2O2 's form and distribution inside, leaving questions regarding the trend and...

Capturing extracellular vesicles: A new technology for isolating disease markers

Biophysicists from Skoltech, MIPT and their colleagues from the company Prostagnost have created a new technology for isolating extracellular vesicles (EV) from biological fluids. Studying vesicles is essential for the diagnosis and treatment of various diseases, including cancer. The new technique not only outperforms methods known to date in purity and yield of EVs, but also is simple, fast,...

Delayed slow ocean response to carbon dioxide removal causes asymmetric tropical rainfall change

Using fossil fuels causes large amounts of carbon dioxide (CO2) to be emitted, which is one of the major greenhouse gases responsible for global warming. The climate changes under increasing CO2 radiative forcing (called "CO2 ramp-up") have been widely projected using numerical experiments. For a carbon-neutral world, more studies have begun to focus on the regional climate responses under...
