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.

If a post is not popular, you will never see it, so views count, but it is the message and not the popularity of it that persuades people, according to a new paper.819 demographically diverse American adults aged 18-35 were shown two YouTube videos either for or against vaping. The pro-vaping videos were commercials for e-cigarette brands. The anti-vaping videos were public service announcements produced by anti-tobacco groups. What was changed was the view numbers that participants saw for the videos. Participants saw view numbers either around 10, 100, 100,000 or 1,000,000.

The remains of 36 bubonic plague victims from a 16th century mass grave in Germany provide evidence that evolutionary adaptive processes, driven by the disease, may have conferred immunity on later generations of people from the region.The researchers collected DNA samples from the inner ear bones of individuals in a mass grave in the southern German city of Ellwangen which experienced bubonic plague outbreaks in the 16th and 17th centuries. Then they took DNA samples from 50 current residents of the town. They compared their frequency spectra - the distribution of gene variants in a given sample - for a large panel of immunity-related genes and found that innate immune markers increased in frequency in modern people from the town compared to plague victims.

Men may be more reluctant to go to a doctor for chest pain but when they get to a care facility, a new analysis finds they get it quicker than women.In this look at the data, all of the patients were younger, from 18-55. Compared with men, women were triaged less urgently, waited longer to be seen, and were less likely to undergo basic tests or be hospitalized or admitted for observation to diagnose a heart attack, according to a demographic look presented at the American College of Cardiology meeting. 

A new analysis finds that nearly 50 percent of people who have children with a partner who suffers from schizophrenia or bipolar disorder themselves meet the criteria for a mental disorder.
