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.
Many new mothers will become pregnant again, and given that a new paper argues for continue anti-smoking campaigns after children are born to reduce the risk of future preterm births.
The longitudinal analysis of surveys results examined the records and histories across 23 years, of 63,540 Australian women with more than one child, who smoked during their first pregnancy.
The Biomedical Advanced Research and Development Authority (BARDA) of the U.S. Department of Health and Human Services and AVITA Medical have halted recruitment for the ongoing pediatric burn study of RECELL spray-on skin for the best possible reason; it has been shown to work.This expanded use just received FDA approval for pediatric burn patients as well as extensive burns covering more than 50 percent of a body’s total surface area.The most common treatment for burns is skin grafting – a painful treatment that can be disfiguring, and sometimes results in additional complications as a child grows. Large burn injuries often do not have enough viable skin available for conventional skin grafting.
Two recent articles showed showed changes in the focus and funding of clinical trials for Alzheimer's disease therapies. And they suggested the change might be evidenced by today, when the U.S. Food and Drug Administration (FDA) seemed ready to approve aducanumab (Biogen) as the first new drug therapy to Alzheimer's patients in nearly 20 years.Namely the emergence of taxpayer-funded government and nonprofit organizations as the primary drivers of research.
The Tibetan plateau covers nearly 1,600,000 square miles. With an average altitude of nearly 14,000 feet, Tibet is called the Roof of the World for good reason. It contains the world's two highest peaks, Mount Everest and K2, and the vast Himalayan mountain range towers higher than anywhere else on Earth.Some researchers contend it has been that height for most of its existence while others argue the roof of the world has gotten higher.
LeRoche Benicoeur/ConceiveEasy; EU Natural Inc.; Fertility Nutraceuticals LLC; SAL NATURE LLC/FertilHerb; and NS Products, Inc. have received warning letters from the US FDA due to their selling fraudulent treatments that claim to help with infertility.Though dietary supplements are mostly exempt from FDA scrutiny due to the Clinton administration giving them a free pass if they put a small disclaimer on the packaging, companies still can't do things like claim to treat cancer, or anything that legitimate medicine does. They can only use marketing to suggest they might make you feel better and other claims that allow naturopaths and homeopaths to make money.
In a recent study, scholars did a prospective review of charts of nearly 300 adult patients hospitalized for COVID-19 at Michigan Medicine during the pandemic's first wave between March and April 2020. They analyzed discharge locations, therapy needs at the time of release and if they needed durable medical equipment or other services..The investigators found that 45 percent of patients hospitalized for COVID-19 experienced significant functional decline after being discharged.
An analysis of ancient fish bones from 30 archaeological sites in Israel and Sinai which date from the Late Bronze Age (1550-1130 BC) until the end of the Byzantine period (640 AD) finds that Judeans commonly ate non-kosher - lacking scales or fins - fish.This finding sheds new light on the origin of Old Testament dietary laws that are still observed by many Jews today - and how well people adhered. Some things become part of culture because they are common. If people in Tennessee banned eating sharks it wouldn't be a huge loss. The ban on finless and scaleless fish deviated from longstanding Judean dietary habits, the authors note.
The Mars Curiosity rover has been on the job since the summer of 2012, exploring Gale Crater on the red planet. It's slow going, it has driven only 25 kilometers to date. But it can be fun to watch, like its
ascent of Mount Mercou, a broad outcrop of rocks on the northern flank of Mount Sharp near the center of the crater, on April 18th 2021.Mt. Sharp is over 2 miles high and Curiosity is the size of a small car. In the picture, it is above a 20-foot-high cliff where it examined the exposed rocks.Credit: NASA/JPL/University of Arizona
An analysis of noble gases dissolved in groundwater finds that the low-to-mid latitude land surfaces at low elevation cooled on average by 11 degrees Fahrenheit during the Last Glacial Maximum - the ice age.Prior to modern times, ice ages were about 90,000 of every 100,000 years. Since it has been 12,000 years since the last one, prior to concern about global warming there was concern about global cooling happening again.Yet 11 degrees is less than some notable marine and low-elevation terrestrial studies that have relied on various proxies to reconstruct past temperatures.
Researchers working with a paralyzed participant who has sensors implanted in his brain have deciphered the brain activity associated with trying to write letters by hand. They used an algorithm to identify letters as he attempted to write them. Then, the system displayed the text on a screen - in real time. Brain-computer interfaces convert thought into action. By attempting handwriting, the study participant typed 90 characters per minute - more than double the previous record for typing with such a "brain-computer interface."
Preclinical findings suggest that targeting the mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) can restore ferroptosis-driven cell death, pointing to new therapeutic strategies that may be used to induce ferroptosis and inhibit tumor growth.Ferroptosis is a form of controlled cell death triggered by the toxic accumulation of lipid peroxides in the cell. Because lipid peroxides are generated through normal metabolic activities, cells also have mechanisms in place to defend against ferroptosis. Glutathione peroxidase 4 (GPX4) is one of the key defense mechanisms identified to date.
A new paper finds that greenhouse gas emissions from standing dead trees in coastal wetland forests are not properly accounted for when assessing the environmental impact of so-called "ghost forests."Ghost forests are what is left of former forests in coastal regions where changes led to shifts in the height of land. As salt water moves in, dead, white, trees are created. North Carolina has some that can even be seen from space.
