The use of ECMO, the most aggressive form of life support in modern medicine, has skyrocketed — but along with miraculous rescues, it can leave patients in limbo, kept alive with machines but with …

A research team led by the University of Cologne has identified the transcription factor Ets21c as a vital regulator of the regenerative system within the adult intestine of the fruit fly Drosophila. The study highlights the existence of trade-off mechanisms between stress resilience and longevity.

The intestinal epithelium is involved in nutrient absorption and digestion, but also serves as a selective barrier that prevents the intrusion of pathogens and toxic substances. The intestine is renewed over an organism’s lifetime through the function of stem cells that are capable of differentiating to maintain the tissue integrity and function.

On the other hand, stem cell malfunctions have been linked to tissue degeneration or cancer development. The research is shedding new light on the molecular basis of the regenerative processes under both favorable and stressful conditions.

The saying “God doesn’t play dice” is meant to suggest that nothing happens by chance. On the other hand, cancer seems like the ultimate happenstance: Don’t we all have a 43-year-old, vegan, triathlete friend fighting cancer? Does this mean that cancer plays dice? According to the traditional model of how cancer develops, yes: Every time a cell divides, you roll a die, and the more years you roll, the greater your chance of rolling an unfortunate mutation that causes cancer. Some young people get very unlucky and some older people get very lucky, but overall, the longer you live, the more times you roll the die, the greater your risk of developing cancer. It makes perfect sense.

Only, a University of Colorado Cancer Center study published in the journal eLife points out a simple problem with this model: Many cancers require more than one activating mutation. In other words, not only one but multiple unlikely bad things have to happen to cause cancer. Think of this like rolling multiple dice, or perhaps like rolling an unlucky number on a single die, multiple times. Say you’re rolling a 100-sided die with “42” being a cancer-causing mutation. You would expect it to take longer to roll four 42s than it does to roll one 42, right?

But the current study shows that no matter the number of unlucky events needed to cause a specific kind of cancer, cancer risk rises equally with age. On average, it takes only one mutation to cause mesothelioma, eleven mutations to cause colorectal cancer, and four mutations to cause pancreatic cancer. But despite the dramatically different Vegas odds of “rolling” one, four and eleven “42s,” the incidence of these cancers goes up uniformly with age, accelerating from about age 60 to about age 85. In this case, it does not, in fact, take longer to roll eleven 42s than it takes to roll one 42.

You’re probably familiar with Johnson & Johnson family products. I remember using it as a child and well into my teen years. But what I, and many people to this day didn’t know, was that their products contain cancer-causing ingredients.

Although Johnson & Johnson labels their bath products as being “baby safe,” they have recently faced lawsuits and public outrage over their baby products and the ingredients they use.

The Environmental Working Group, a non-profit environmental research organization, describes the dangers of the ingredients used in Johnson & Johnson products. These ingredients include quaternium-15 and 1,4-dioxane.

21st Century Medicine has developed an entire platform technology focused on the creation and commercialization of hypothermic preservation and cryopreservation techniques that enable protection, preservation, transportation, storage & future use of valuable living systems. These developments have taken science far beyond conventional preservation limits. 21CM scientists continue to prove long-term protection and preservation of complex living systems is not only possible, but commercially viable.

It means that a vital link has been created that we call “Bio Logistics”.

Biopharmaceutical companies get a larger window in which to test new drug candidates on viable premade and cryopreserved tissue slices that function like fresh.

WASHINGTON (AP) — U.S. women will soon have another drug option designed to boost low sex drive: a shot they can give themselves in the thigh or abdomen that raises sexual interest for several hours.

The medication OK’d Friday by the Food and Drug Administration is only the second approved to increase sexual desire in a women, a market drugmakers have been trying to cultivate since the blockbuster success of Viagra for men in the late 1990s. The other drug is a daily pill.

The upside of the new drug “is that you only use it when you need it,” said Dr. Julia Johnson, a reproductive specialist at UMass Memorial Medical Center who was not involved in its development. “The downside is that it’s a shot — and some people are very squeamish.”

Thousands of years ago, glaciers covered much of the planet. Oceans receded as water froze in massive sheets of ice blanketing the North American continent. As the ice age ended, glaciers melted. Massive river deltas flowed out across the continental shelf. The oceans rose, and fresh water was trapped in sediments below the waves. Discovered while drilling for oil offshore in the 1970s, scientists thought these “isolated” pockets of fresh water were a curiosity. They may instead prove to be a parched world’s newest source of fresh water.

As told in the latest issue (paywall) of the peer-reviewed journal Scientific Reports, scientists from Columbia University and the Woods Hole Oceanographic Institution spent 10 days on a research ship towing electromagnetic sensors from New Jersey to Massachusetts. By measuring the way electromagnetic waves traveled through fresh and saline water, researchers mapped out fresh-water reservoirs for the first time.

It turns out the subterranean pools stretch for at least 50 miles off the US Atlantic coast, containing vast stores of low-salinity groundwater, about twice the volume of Lake Ontario. The deposits begin about 600 ft (183 m) below the seafloor and stretch for hundreds of miles. That rivals the size of even the largest terrestrial aquifers.

The scene resembles a typical blind speed-dating event: 13 women and 13 men, seated on either side of a bamboo screen in an upmarket Tokyo restaurant, are chatting in pairs on a strictly timed three-minute rotation.

But the doctor hovering on the fringes and the scientific documents held in the participant’s hands, however, offer a hint that this is no ordinary dating event: for everyone attending has undergone a DNA test in a bid to find their best romantic match.

Welcome to the world of DNA matchmaking. Forget hobbies, professions, ages or nose sizes: one critical new criteria for finding the perfect partner was recently added to Japan’s fast-paced dating world, with the launch of a new service that promises to find love based on genetic compatibility.
