Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
Volunteering often makes us feel good but does it mean better health? Epidemiologists in a new paper argue it does, but the confounders are obvious; parents who take their kids to volunteer are often wealthier and in better health and on surveys about their kids claim better outcomes.The work originated from parent-reported survey data of 22,126 children (6 to 11 years) and 29,769 adolescents (12 to 17 years) in the 2019 to 2020 National Survey of Children’s Health. The authors adjusted and weighted the data to reflect their beliefs about the demographic composition of youths in each state.
A phrase like 'spring in your step' is usually meant to evoke enthusiasm or happiness but a new study finds that its mechanism, the spring-like arch in our feet, did help us walk on two feet. Just in a different way than previously believed.Most believe that the raised arch of the foot helps us walk by acting as a lever which helps to lift the body into the next step by propelling the body forward but the new work argues that the recoil of the flexible arch repositions the ankle upright for more effective walking - and the effects in running are even greater.
There were 93 school shootings in the US in a recent two-year period but they were rarely committed by students. Sometimes they were former students of the school but new a survey analysis say their mental health issues may have been aggravated by memories of bullying.
A wearable, pocket-sized, automated insulin delivery device has been approved by the US Food and Drug Administration (FDA). The company calls is the iLet Bionic Pancreas but it's obviously not bionic any more than String Theory is a scientific theory. However, it is now available in this universe for the almost two million Americans with type 1 diabetes.
Sepsis causes 11 million deaths annually so preventing that requires prompt recognition, source control, antibiotics, fluids and vasopressors.Sometimes adjunctive therapies such as orticosteroids help but the science is inconclusive. A recent study was designed to evaluate the role of corticosteroids in the management of patients with septic shock and the contradictory effects on mortality as recorded in past research and treatment.
In recent geological history, 90,000 of every 100,000 years have been ice ages. It's been 12,000 years since the last one so we may be due.Or not. Climate science has a few rules but a lot of exceptions and 700,000 years ago a big exception occurred. At that time the planet experienced a “warm ice age” and it permanently changed the climate cycles on Earth. Though it became warmer and with more rain, the polar glaciers also expanded. Geological data in combination with computer simulations published in Nature Communications hopes to lend insight into this paradox.
Screening is underway to find a patient for the world's first bladder transplant in humans.
If a vaccine requires cold storage for shipping, many areas where infrastructure doesn't hold up are unable to receive them. A possible solution to this problem is a mobile vaccine printer that could produce hundreds of vaccine doses in a day.The printer produces patches with hundreds of microneedles containing the vaccine. The patches can be attached to the skin, allowing the vaccine to dissolve without the need for a traditional injection. Once printed, the vaccine patches can be stored for months at room temperature.In their paper, the scientists used the printer to produce thermostable Covid-19 RNA vaccines that could induce a comparable immune response to that generated by injected RNA vaccines, in mice.
New results show that the number of reported cancer cases in the National Cancer Database during the COVID-19 pandemic declined by 14.4 percen, which means over 200,000 cancer cases were not diagnosed and/or treated.The reasons were unclear, perhaps concern about catching COVID-19 or being symptomatic but not wanting to go to the doctor because of media claims about those unable to get care for SARS-CoV-2. The results are more obvious; a lot of people are at greater risk.
New research shows that dairy products have made life easier for thousands of years. Even in places that are a challenge for anyone, like the Tibetan Plateau - the “roof of the world.”Genetic engineering due to natural selection at several genomic loci certainly made early Tibetans better able to survive high elevations, but those did nothing for calorie requirements. A new study finds that dairy made it possible. Ancient proteins from the dental calculus of 40 human individuals from 15 sites across the interior plateau show that dairying was introduced onto the hinterland plateau by at least 3,500 years ago.
Bud Light may create a marketing campaign to try and increase its brand but when it comes to pricing, experimentation isn't needed. If you want the most sales, target people who shop prices.It is certainly true that if you have a product during a fad wave, you can charge more. Or, if supplies of a product are scarce, prices will be higher. Yet limited supply means limited revenue. The big money is instead in those who are price shoppers.
To make solar power viable, there need to be gigantic installations in remote locations. Then there need to be new power lines equivalent to every paved road in America. Then the grid needs to be modernized with battery storage.None of that is happening any time soon but what may spur at least grid improvements is the reliance on natural gas. Though alternative energy gets mandates and subsidies conventional fuel supplies 80 percent of American energy, but natural gas needs energy to get from place to place. While most of that is still, fittingly, supplied by natural gas, in places where it is supplied by electricity, or even less reliable solar electricity, pipelines are far more subject to outages.
