NAIROBI, Kenya (AP) – Africa’s next-generation power projects are increasingly being built around solar power, wind power and battery storage as governments and investors move away from coal and large hydroelectric dams for cheaper, faster and more reliable electricity.This shift is evident in the $1.5 billion energy deal between China and Zambia announced in early May, which includes three separate 300 megawatt projects spanning solar, wind and coal-fired power. While the introduction of coal underscores the continent’s continued need for reliable baseload electricity, African countries facing rising fuel import prices, declining grid reliability and increased industrial demand as a result…
The climate crisis is accelerating the global rise in antibiotic resistance, posing a serious threat to human health, figures show, showing a rise in antibiotic resistance genes in Salmonella bacteria, experts say.Antibiotic resistance is one of the fastest growing threats to global health. It can affect people of all ages in any country, and estimates say it already kills more than 1 million people a year.A study led by researchers from the UK, France, Australia, Switzerland and China has revealed how climate change is linked to rising antibiotic resistance in Salmonella enterica, one of the world’s most common bacterial diseases.Climate…
Beginner chess players rely heavily on their ability to recognize familiar board patterns rather than purely calculating future moves, suggesting that memorization of specific piece placements facilitates early skill development. These results, published in the Journal of Sports Sciences, show that even novices process real game scenarios quite differently than a random combination. This study shows that integrating visual pattern training from the beginning of a player’s behavior can be highly effective in building future abilities. Chess skill is traditionally measured by the Elo rating system. This mathematical model assigns contestants variable numerical scores based on their win/loss history against…
Listen to the audio version of this article (generated by AI).Vermont on Tuesday became the first U.S. state to ban the herbicide paraquat, backed by lawmakers who cited concerns about research showing the chemical could cause an incurable brain disease known as Parkinson’s disease. After considering the bill for several days, Governor Phil Scott signed it on May 26. The bill would go into effect Nov. 1, but the new law includes a provision that would allow state regulators to issue special permits for the use of paraquat on orchards, berries and other crops until Dec. 31, 2030. The bill…
Health tech companies Wheel and b.well Connected Health are partnering to deliver turnkey infrastructure for next-generation AI-first virtual care. There are two converging trends driving innovation in healthcare. It’s an AI-first healthcare experience and a consumer-centric model. Consumer health data is pervasive and integrated into everyday life, with information from apps, wearables, devices, and medical records. At the same time, retail stores and pharmacies are becoming access points for care, and life sciences companies are gaining direct access to consumers. The Centers for Medicare and Medicaid Services (CMS) is working to open up access to patient health data. According to…
When it comes to free speech on college campuses, students are generally reluctant to punish offensive speech unless it’s very harsh or targeted at minorities. A new research experiment reveals that most undergraduate students believe that marginalized communities deserve special protection from offensive speech, but these values are often abandoned when students are pushed by their own strong political ideologies. The results of this study were published in the journal Science Advances. Recent political protests have turned universities into highly visible battlegrounds over the limits of acceptable expression. In the wake of the October 2023 Hamas attack and the ensuing…
Researchers have solved a long-standing mystery about why physical force slows cancer growth. The answer could change the way cancer is treated. A multidisciplinary team from University of Galway CÚRAM, Taighde Éireann-Research Ireland Center for Medical Devices and the University of Leuven in Belgium built an innovative AI-accelerated computational model to test the theory. The findings suggest that learning how to harness the pressure of physical forces against tumors could open up a whole new role for treatments known as mechanotherapy in the fight against cancer. This study Proceedings of the National Academy of Sciences at https://www.pnas.org/doi/10.1073/pnas.2523159123 Dr. Irish Senthilkumar,…
A leptospirosis outbreak that affected more than 200 dogs in Los Angeles County in 2021 has revealed critical gaps in vaccination practices and raised widespread concerns about the spread of the disease among animals and humans, according to a new study led by the University of California, Davis. Leptospirosis is a bacterial disease that can cause serious illness in dogs, including acute kidney injury. In severe cases, the dog may die. Humans can also contract the disease through contact with contaminated animal urine (especially urine from rodents and livestock) or contaminated water. In humans, it often causes flu-like symptoms that…
Researchers have created a new global map showing where unusual volcanic rocks associated with rare earth elements are found, revealing a surprising connection to the oldest and thickest parts of Earth’s continents. An international team led by scientists from the University of Cambridge’s School of Earth Sciences has found that these rare earth-rich igneous rocks are strongly linked to fluctuations in the lithosphere, the planet’s hard outer shell. Their findings suggest that the thick lithosphere plays a major role in forming the types of rocks that can concentrate valuable metals over time. This study natural earth sciencecould help scientists identify…
Scientists have known for more than 20 years that all cells use a strategy called RNA interference to regulate gene expression, but the new study describes for the first time how specific proteins manage the step-by-step process of assembling molecular complexes that play regulatory roles. Among the surprising discoveries is the suppression of the interference’s target messenger RNA (mRNA), a protein whose instructions are carried by this same mRNA, which also helps complete the final step in assembling the complex that inhibits gene expression. Overall, this study shows that management proteins transform precursor complexes into mature RNA-induced silencing complexes (RISCs)…
