Earthquakes occur when stress built up in the Earth’s crust is suddenly released along cracks known as faults. These faults often form where giant plates become stuck moving past each other, allowing pressure to build for years or even centuries before rupture occurs. In Southern California, the two most important fault systems in the region are the San Andreas and San Jacinto faults. Together they account for most of the tectonic movements in the region. At Cajon Pass, northeast of Los Angeles, the two systems are close together. This is a geologically complex area where cracks on one fault can…

DAKAR, SENEGAL – The Ebola outbreak in Congo and Uganda has claimed more than 200 lives in its first month, making it the deadliest outbreak yet, with up to 35,000 people suspected of having been in contact with it, the Africa Centers for Disease Control and Prevention said Thursday. Dr. Wessam Mankoula, a medical epidemiologist at the Africa CDC, said that with 894 confirmed cases so far, this outbreak is three times worse than the previous outbreak in Uganda in 2000, when 281 people were infected during the same period. The latest number of cases is believed to be even…

Stressful situations tend to reduce the desire to mate in many animal species, but the exact brain mechanisms behind this response remain difficult to pin down. Recent research published in journals iscience We provide evidence that male Drosophila melanogaster courtship behavior is suppressed when confined to a small space. The findings suggest that the brain’s dopamine system is required to maintain this low sexual motivation even after the stressful event is over. When animals experience physical or psychological stress, changes occur in the brain that can alter basic physiological functions and behavior. These changes can last long after the stressful…

Four years after he joined the New York drugmaker’s ranks in the wake of the unexpected fallout from the coronavirus pandemic, Pfizer Chief Financial Officer Dave Denton will soon bid farewell to the pharmaceutical industry and pivot back to the consumer goods industry. The baton will be passed to Denton on August 15, Pfizer announced Thursday. The CFO will highlight “opportunities for non-pharmaceutical professionals in the consumer goods space,” and Cécile Guegan, vice president of finance for Pfizer’s global biopharmaceutical business, will assume the interim role of finance director. Pfizer also noted that it has begun an internal and external…

What is Novo Nordisk’s secret weapon to turn the tide against Eli Lilly and win the current market competition for oral GLP-1 obesity drugs? Name recognition. Jim Hickey, an analyst at Spherix Global Insights, said he studies competition by surveying 50 primary care physicians (PCPs) and 50 endocrinologists in the U.S. and by writing monthly reports on the uptake of new drugs that hit the market earlier this year. “It’s been interesting to see how strong Novo Nordisk came out of the gate,” Hickey said in an interview with Fierce. “As far as we can see, this is a very…

Recent psychological research is investigating how socially unpleasant personality traits affect employees’ mental health and sense of purpose. The findings of this study indicate that narcissism is associated with improved psychological well-being through higher emotional intelligence, whereas psychopathy predicts the opposite outcome. The study was published in the journal Acta Psychologica. The Dark Triad represents three negative and socially aggressive personality traits. These exact traits include narcissism, Machiavellianism, and psychopathy. Although these are distinct concepts, they share a core foundation of emotional coldness, interpersonal manipulation, and a general lack of empathy for others. Narcissism usually involves grandiosity, an exaggerated sense…

If you’re an older adult, getting the shingles vaccine may lower your risk of developing dementia. A new study found that residents of elderly care facilities who received at least one dose of the shingles vaccine, known as Shingrix, the only shingles vaccine available in the United States, were 24 percent less likely to develop dementia over a four-year period than those who did not receive the vaccine, according to results published this week in the peer-reviewed journal Annals of Internal Medicine. This study adds to growing evidence of a link between viral infections and cognitive decline. STAT+ exclusive story…

For many people, the plague brings to mind rats, crowded medieval towns, and the devastating epidemic that spread throughout Europe during and after the Middle Ages. New research suggests the disease’s deadly history goes back even further. Research published in nature Researchers found that plague was already killing people in small hunter-gatherer groups 5,500 years ago, thousands of years before agricultural communities and cities emerged. An international team of scientists examined ancient DNA from human remains recovered from four hunter-gatherer cemeteries near Lake Baikal in eastern Siberia. By sequencing genetic material stored inside ancient teeth, researchers reconstructed the bacterial genome…

The National Science Foundation on Thursday reversed its decision to dismantle its sprawling ocean monitoring network. fierce opposition Hearing from Democratic lawmakers and scientists who rely on this data to track everything from ocean circulation to extreme weather events.NSF issued a statement “We appreciate the concerns raised by a wide range of stakeholders,” he said, adding that efforts to remove or neutralize the equipment will be halted. It also said it would redeploy equipment already removed from the sea and convene a committee of experts to decide on the future of the network. Ocean Observatory Initiative is a network of…

Recent research published in journals nature We reveal how certain stress hormones help solidify the brain’s neural connections during early development. This study provides evidence that star-shaped brain cells called astrocytes sense this hormone and turn off periods of high brain plasticity. These findings suggest new ways to understand how the brain matures and how early-life stress disrupts this natural developmental timeline. When animals and humans are young, their brains are highly susceptible to mold growth. This flexibility, known as plasticity, allows the brain to learn from sensory experiences and adapt to its surrounding environment. Scientists refer to this period…
