Silicon has powered computer chips for decades, but engineers are increasingly facing the material’s physical limits. To continue making electronic devices smaller and more powerful, researchers are exploring ways to combine silicon with new ultra-thin materials. One group of promising materials is known as transition metal dichalcogenides (TMDs). Among the leading candidates is molybdenum disulfide. Molybdenum disulfide is a three-atom-thick material that consists of a layer of molybdenum between two layers of sulfur. Single atomic layer removal For future transistors that combine silicon and TMD materials, manufacturers may need to selectively remove atoms from just the top sulfur layer, leaving…

Superconductors could one day help power a new generation of ultra-efficient electronics, but major technical obstacles have kept the technology largely confined to the laboratory. Now, scientists at Sweden’s Chalmers University of Technology have developed a new approach to one of the field’s biggest challenges: sustaining superconductivity at high temperatures while withstanding strong magnetic fields. This advance could bring superconducting technology closer to practical applications in electronics, energy systems, and quantum devices. Modern digital devices, data centers, and information and communication technology (ICT) networks account for an estimated 6-12% of global electricity consumption. As energy demand continues to increase, researchers…

When Congress approved a $1 billion Energy Resilience Fund for Puerto Rico in 2022, the money was desperately needed. Multiple hurricanes have devastated the island’s notoriously fragile power grid, and lawmakers envisioned using the money to support rooftop solar and battery storage systems that could provide strong backup power in emergencies. The Biden administration’s Department of Energy has developed a plan to distribute funds to about 40,000 low-income Puerto Ricans, many of whom live with health conditions that require access to reliable electricity. Biden officials envision a network of solar power and battery storage systems that would keep medically vulnerable…

Listen to the audio version of this article (generated by AI).Air pollution from New Mexico’s large, concentrated dairy farms causes an estimated $217 million in annual health care costs, with most of the damage coming from ammonia emissions that form dangerous particulate matter, according to a new study. of Learning before printing from Journal of Agricultural Resource Economics estimated for the first time the cost of air pollution to the state’s dairy industry and found that the health costs of raising dairy cows in concentrated animal feeding operations (CAFOs) offset approximately 15% of the industry’s revenues. The researchers also used…

The European Chemicals Agency (Echa) has formally recommended the classification of trifluoroacetic acid (TFA), a breakdown product of certain pesticides and refrigerants, as a reproductive toxicant. It may impair fertility and harm the fetus. The decision, announced on June 10 and based on the conclusions of Echa’s Risk Assessment Committee (RAC) earlier this month, could have significant implications for the regulation of pharmaceuticals, pesticides and refrigerants. The RAC’s opinion, based on animal studies, will be forwarded to the European Commission. Echa also supported the RAC’s conclusion that TFA should be designated as persistent, mobile, and toxic. The EU classifies TFA…

When scientists sequenced the human genome in 2003, deciphering the entire human genetic code, many hoped it would unlock the secrets of disease. However, genetics only explain about 10% of the risk. The other 90% is environmental, and diet plays a big role. Around the world, approximately one in five adults over the age of 25 die from poor diets. In Europe, cardiovascular diseases account for almost half of deaths. But despite decades of advice to eat less fat, salt and sugar, obesity and diet-related diseases continue to rise. Clearly, something is missing in the way we think about food.…

Minimally invasive surgery that blocks abnormal blood vessels around the knee may provide long-term symptom relief for osteoarthritis patients, according to a new study published June 16 in the journal Arthritis. RadiologyJournal of the Radiological Society of North America (RSNA). Osteoarthritis is the most common type of arthritis and a leading cause of disability worldwide. This condition can cause joint inflammation, stiffness, reduced mobility, and pain caused by sensory nerves. The World Health Organization estimates that more than 365 million adults worldwide have knee osteoarthritis. “For many patients with knee osteoarthritis, there is a major gap in today’s treatment,” says…

Career interest tests are very helpful in helping teenagers and young adults decide which career to pursue. A new study from Michigan State University challenges the assumption that vocational interests are only relevant for early career decisions. In fact, it remains relevant even into adulthood. This study Journal of Personality and Social Psychologywere the first to examine whether interests predict work, relationship, and community outcomes in midlife and later adulthood. The study followed more than 8,000 adults over 11 years and found that career interests predicted important life outcomes in adulthood and beyond. Participants first completed a career interest assessment…

Wearable exoskeletons can reduce physical stress in the workplace and help protect employees from injury, but the technology is not yet widely available. New research published in Pro Swan Here’s why, according to engineers at the University of Texas at El Paso: This technology remains too complex and unwieldy for routine use. “Our study suggests that an important factor that influences the success of exoskeletons may be largely overlooked: how easily they can be assembled, put on and taken off,” said Dr. Arunkumar Pennathur of UTEP, who led the study. “The exoskeletons that are successful in the workplace may not…

High-calorie food cues extended perceptual time in adolescent girls, revealing how media pressure and body image shape even basic cognitive processing. Paper: Beyond calories: The role of media pressure and body appreciation in shaping time perception of food cues in female adolescents. Image credit: Andrii Yalanskyi / Shutterstock In the Journal’s recent “Press Articles” scientific reportresearchers evaluated the interaction between food cues, psychological factors, and time perception in adolescent females. Adolescence is characterized by increased sensitivity to sociocultural factors such as body image and media pressure. In this context, everyday stimuli such as food can acquire substantial emotional value and…
