(CREDIT: American College of Cardiology) To delve into the mechanisms behind the psychological and cardiovascular advantages of physical activity, Dr. Ahmed Tawakol, a cardiologist and researcher at MGH’s Cardiovascular Imaging Research Center, along with his team, scrutinized medical records and data from 50,359 participants in the Mass General Brigham Biobank who completed a physical activity survey. Additionally, a subgroup of 774 participants underwent brain imaging tests and stress-related brain activity measurements. Over a median follow-up period of 10 years, approximately 12.9% of participants developed cardiovascular disease. Comparing those who met physical activity recommendations with those who did not, the researchers found that the former group had …

Invisible face mask reduces airborne virus transmission

Invisible face mask reduces airborne virus transmission

The device creates a filtered airflow in front of the user’s face, reducing the concentration of viruses in the air and therefore the risk of infection. (CREDIT: KTH) Amidst the COVID-19 pandemic, respiratory masks played a crucial role in combatting virus transmission. However, they often posed discomfort and communication barriers. Ricardo Vinuesa, from KTH Royal Institute of Technology, leads a study presenting an innovative solution potentially revolutionizing preventive measures against airborne infections. Picture a cap equipped with a built-in fan blowing air in front of your face. This isn’t a joke but a novel innovation. Through advanced simulations of virus particle spread, an international team devised a simple, cost-effective solution significantly reducing airborne virus transmission risk. More effective than traditional face masks, this concept redirects airflow away from the user, surpassing mask efficacy. “Face masks and a distance of 2 meters are helpful, but actively directing virus-laden air downwards is even better. Our solution not only outperforms masks but also fosters comfortable interaction,” Vinuesa elaborates. With partial face coverage, the device enhances social interaction, particularly …

New drug substantially reduces both weight and cholesterol levels, study finds

Scientists have achieved significant weight loss in obese mice by introducing medication directly into the liver via a novel nanogel carrier. (CREDIT: Creative Commons) In a groundbreaking discovery, scientists have achieved significant weight loss in obese mice by introducing medication directly into the liver via a novel nanogel carrier. This innovative approach circumvents the issues associated with systemic drug administration, markedly reducing potential side effects. The significance of this method becomes apparent when considering the broader picture. A staggering one hundred million Americans suffer from obesity and related cardiometabolic disorders, comments S. Thai Thayumanavan, a renowned biomedical engineer and chemist from the University of Massachusetts Amherst. “We became pretty excited about this work,” he reveals. The brilliance of this approach is encapsulated, quite literally, in the nanogel. These minuscule carriers are loaded with a synthetic thyroid hormone drug termed a thyromimetic. Essential for liver metabolism, thyroid hormones can be ineffective when taken systemically and carry adverse side effects.

Farmers warn ‘crisis is building’ as record rainfall drastically reduces UK food production | Farming

Record-breaking rain in recent months has drastically reduced the amount of food produced in the UK, farming groups have said. Livestock and crops have been affected as fields have been submerged since last autumn. It has been an exceptionally wet 18 months. According to the Met Office, 1,695.9mm of rain fell from October 2022 to March 2024, the highest amount for any 18-month period in England in recorded history. The Met Office started collecting data in 1836. The UK will be reliant on imports for wheat in the coming year and potentially beyond because of the drastic reduction in yields. Prices of goods such as bread and other food made using grains are already rising and are likely to rise further, according to the Agriculture and Horticulture Development Board (AHDB). Wheat production is down 15% since November, the biggest reduction in cropped areas since 2020. Oilseed rape is down 28%, the biggest reduction since the 1980s, and winter barley is down 22% at 355,000 hectares, the biggest reduction since 2020. The areas that have been …

Medical discovery reduces fear, anxiety, and depression, study finds

Researchers have added a new dimension to Tob’s repertoire: a potential treatment for depression, fear, and anxiety. (CREDIT: Creative Commons) In the nuanced landscape of molecular biology, few genes have captured the intrigue of the scientific community as the Tob gene has. Discovered in 1996 in Professor Tadashi Yamamoto’s lab in Japan, Tob’s influence stretches from cancer proliferation to the intricate dance of the cell cycle and the subtleties of immune responses. “This research is about understanding stress-resilience,” Dr. Mohieldin Youssef, a pivotal figure in this groundbreaking study and a former PhD student in OIST’s Cell Signal Unit, elucidated. Prof. Yamamoto, leading the unit, has been at the helm of this discovery journey. “The presence of the gene helps with stress-resilience and if it’s removed, there’s an increase in depression, fear, and anxiety.” An MRI of the hippocampus and the pre-frontal cortex when the Tob gene was removed. This MRI allowed the researchers to determine that the connectivity between the hippocampus and the pre-frontal cortex had been altered. The image is from the press release …

NY court reduces Trump’s bond to 5 million as he appeals fraud

NY court reduces Trump’s bond to $175 million as he appeals fraud

After James won the judgment, she didn’t seek to enforce it during a legal time-out for Trump to ask the appeals court for a reprieve from paying up. That period ended Monday, though James could have decided to allow Trump more time. James told ABC News last month that if Trump doesn’t have the money to pay, she would seek to seize his assets. She didn’t detail the process or specify what holdings she meant, and her office has declined more recently to discuss its plans. Meanwhile, the office has filed notice of the judgment, a technical step toward potentially moving to collect. Trump maintained on social media on Friday that he has almost $500 million in case but on Monday said that he’d like to be able to use some on his presidential run. He asserted that James and Engoron, who’s also a Democrat, “don’t want me taking cash out to use it for the campaign.” If the penalty is ultimately upheld, the attorney general could go after Trump’s bank and investment accounts. There’s also …

Sleep apnea nasal spray reduces severity in 70% of trial cases

Sleep apnea nasal spray reduces severity in 70% of trial cases

Researchers have found that a nighttime nasal spray could help alleviate the severity of sleep apnea and decrease blood pressure levels. (CREDIT: Creative Commons) Researchers in Australia have found that a nighttime nasal spray could help alleviate the severity of sleep apnea and decrease blood pressure levels. Sleep apnea, a common respiratory condition, disrupts breathing during sleep due to narrowed or collapsed airways, leading to frequent awakenings throughout the night. Professor Danny Eckert from the College of Medicine and Public Health explains that sleep apnea is associated with various health issues such as cardiovascular disease, stroke, obesity, diabetes, anxiety, and depression. Despite continuous positive airway pressure (CPAP) machines being an effective treatment, many people struggle to tolerate them. Using a bedtime nasal spray that activates throat muscles can reduce the severity of sleep apnea and lower blood pressure. (CREDIT: Flinders University) The study aimed to assess the impact of a new nasal spray containing a potassium channel blocker on sleep apnea severity. Lead author Dr. Amal Osman explains that potassium channel blockers enhance muscle activity …
