randomErr writes: A new patent has been filed for a innovative brewing technique that incorporates a live strain of good bacteria into the brewing process. Researchers at NUS (National University of Singapore) have created a probiotic sour beer that may boost immunity and improve gut health. The bacteria Lactobacillus paracasei L26 is capable of neutralizing toxins and viruses and regulating the immune system. Chan Mei Zhi Alcine, of the Food Science and Technology Program at NUS said, “While good bacteria are often present in food that have been fermented, there are currently no beers in the market that contain probiotics. Developing sufficient counts of live probiotics in beer is a challenging feat as beers contain hop acids that prevent the growth and survival of probiotics. As a believer of achieving a healthy diet through consuming probiotics, this is a natural choice for me when I picked a topic for my final-year project.” Read more of this story at Slashdot.

Researchers Create New Probiotic Beer That Boosts Immunity

Berkeley found a birth control that was hormone-free, 100 percent natural, resulted in no side effects, didn’t harm either eggs nor sperm, could be used in the long-term or short-term, and — perhaps the best part of all — could be used either before or after conception, from ancient Chinese folk medicine… “Because these two plant compounds block fertilization at very, very low concentrations — about 10 times lower than levels of levonorgestrel in Plan B — they could be a new generation of emergency contraceptive we nicknamed ‘molecular condoms, ‘” team leader Polina Lishko.

Gulping down an artificially sweetened beverage not only may be associated with health risks for your body, but also possibly your brain, a new study suggests. From a report: Artificially sweetened drinks, such as diet sodas, were tied to a higher risk of stroke and dementia in the study, which published in the American Heart Association’s journal Stroke on Thursday. The study sheds light only on an association, as the researchers were unable to determine an actual cause-and-effect relationship between sipping artificially sweetened drinks and an increased risk for stroke and dementia. Therefore, some experts caution that the findings should be interpreted carefully. No connection was found between those health risks and other sugary beverages, such as sugar-sweetened sodas, fruit juice and fruit drinks. Read more of this story at Slashdot. 
schwit1 quotes ScienceAlert: In experiments involving mice, the team found that lungs produce more than 10 million platelets (tiny blood cells) per hour, equating to the majority of platelets in the animals’ circulation. This goes against the decades-long assumption that bone marrow produces all of our blood components. Researchers from the University of California, San Francisco also discovered a previously unknown pool of blood stem cells that makes this happen inside the lung tissue — cells that were incorrectly assumed to mainly reside in bone marrow. “This finding definitely suggests a more sophisticated view of the lungs — that they’re not just for respiration, but also a key partner in formation of crucial aspects of the blood, ” says one of the researchers, Mark R. Looney. The platelet-producing cells actually migrate from the bone marrow to the lungs. Read more of this story at Slashdot. 
“Scientists have extracted long-dormant microbes from inside the famous giant crystals of the Naica mountain caves in Mexico — and revived them, ” reports the BBC. An anonymous reader writes: “The organisms were likely to have been encased in the striking shafts of gypsum at least 10, 000 years ago, and possibly up to 50, 000 years ago, ” according to the BBC, which calls the strange lifeforms “another demonstration of the ability of life to adapt and cope in the most hostile of environments.” With no light, extremophile species must “chemosynthesise, ” deriving all their energy by extracting minerals from rocks. These ancient microbes “are not very closely related to anything in the known genetic databases, ” according to the new director of NASA’s Astrobiology Institute, who helped conduct the research, and believes that the microbes could help suggest what life might look like on other planets. The BBC adds that many other scientists “suspect that if life does exist elsewhere in the Solar System, it is most likely to be underground, chemosynthesising like the microbes of Naica.” Read more of this story at Slashdot.
