Technology’s impact on worker well-being

In the traditional narrative of the evolving 21st century workplace, technological substitution of human employees is treated as a serious concern, while technological complementarity -- the use of automation and artificial intelligence to complement workers -- is viewed as a good thing. But a new study tells a more nuanced story, demonstrating that the integration of automation and AI in the...

Researchers develop a new way to control and measure energy levels in a diamond crystal

Physicists and engineers have long been interested in creating new forms of matter, those not typically found in nature. Such materials might find use someday in, for example, novel computer chips. Beyond applications, they also reveal elusive insights about the fundamental workings of the universe. Recent work at MIT both created and characterized new quantum systems demonstrating dynamical...

Researchers set 'ultrabroadband' record with entangled photons

Quantum entanglement—or what Albert Einstein once referred to as "spooky action at a distance"— occurs when two quantum particles are connected to each other, even when millions of miles apart. Any observation of one particle affects the other as if they were communicating with each other. When this entanglement involves photons, interesting possibilities emerge, including entangling the...

Scientists identify G-Exos as a nanocarrier for miRNA transfer to stimulate neural differentiation of stem cells

Differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) into functional neural cells is of tremendous significance to treat neural diseases. However, the limited neural differentiation of BMSCs remains a major challenge. Recent studies suggest that miRNAs may play a crucial role in regulating the neural differentiation of stem cells as effective signaling molecules. Due to their...

Sun releases significant solar flare

The Sun emitted a significant solar flare peaking at 11:35 a.m. EDT on Oct. 28, 2021. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

New gene-editing technique offers scientists ability to 'turn on' enzymes that cause DNA base mutations

Targeted mutations to the genome can now be introduced by splitting specific mutator enzymes and then triggering them to reconstitute, according to research from the Perelman School of Medicine at the University of Pennsylvania. Led by graduate student Kiara Berríos under the supervision of Rahul Kohli, MD, Ph.D., an associate professor of Infectious Diseases at Penn, and Junwei Shi, Ph.D., an...

Biologists find gene that creates extra vacuoles in plant cells

Sometimes plant cells don't have just one large central cavity, or vacuole, but several. These can even have different functions. How is that possible? A team led by UvA biologists Ronald Koes and Francesca Quattrocchio took another step towards solving this fundamental biological riddle. Their discovery has been published in the leading scientific journal Cell Reports.

New hydrogen storage material steps on the gas

Hydrogen is increasingly viewed as essential to a sustainable world energy economy because it can store surplus renewable power, decarbonize transportation and serve as a zero-emission energy carrier. However, conventional high-pressure or cryogenic storage pose significant technical and engineering challenges.

Large wild herbivores reduce the fast biodiversity decline of plants in a tropical forestry hotspot

For 10 years, in the Atlantic Forests, researchers compared forests used by herbivorous mammals, including the lowland tapir (Tapirus terrestris) and the white-lipped peccary (Tayassu pecari), and areas in which these animals have been barred from access due to exclosure plots (fences). The main conclusion is that the areas used by these herbivores show lower loss of diversity than fenced areas.

Social mobility is influenced by where ancestors lived

There are clear and enduring regional divides across Great Britain, finds an intergenerational assessment of the social mobility of British families between 1851 and 2016, carried out by University College London (UCL) researchers at the Consumer Data Research Centre (CDRC).

NASA's Juno: Science results offer first 3D view of Jupiter atmosphere

New findings from NASA's Juno probe orbiting Jupiter provide a fuller picture of how the planet's distinctive and colorful atmospheric features offer clues about the unseen processes below its clouds. The results highlight the inner workings of the belts and zones of clouds encircling Jupiter, as well as its polar cyclones and even the Great Red Spot.

Cryptocurrency isn’t private—but with know-how, it could be

There’s probably no such thing as perfect privacy and security online. Hackers regularly breach corporate firewalls to gain customers’ private information, and scammers constantly strive to trick us into divulging our passwords. But existing tools can provide a high level of privacy—if we use them correctly, says Mashael Al Sabah, a cybersecurity researcher at the…
