"A Danish fashion brand has launched a Kickstarter to fund the creation of boxers, socks and t-shirts that it claims you “won’t need to wash for weeks”.
The NASA-inspired garments, created by Organic Basics, are treated with a high-tech silver formula that supposedly kills bacteria and odours, allowing the wearer to feel fresher for longer. The pants are also designed to be breathable, with ventilation in “critical sweat zones” - make of that what you will.
If the thought of day-old pants is enough to make you squirm, perhaps the environmental benefits will change your mind. The products are aimed at the eco-conscious, as less washing means less water waste and less energy usage.,"

"A. Coconut oil’s image has gotten a makeover in recent years, and many natural food stores stock the product. But despite “a lot of hype about it,” said Dr. Alice H. Lichtenstein, a Tufts University professor of nutrition science and policy who is vice chair of the federal government’s dietary guidelines advisory committee, “there’s virtually no data to support the hype.”
Coconut oil is high in saturated fatty acids, and saturated fat has been linked to high cholesterol levels and heart disease. Though critics have recently raised questions about the scientific evidence for the link, longstanding dietary guidelines urge Americans to reduce saturated fat intake to less than 10 percent of daily calories, or about 20 grams for a 2,000-calorie-a-day diet."
(...)
"Refined, bleached and deodorized, or R.B.D., coconut oil, which has been treated with solvents and subjected to intense heat, raises cholesterol so reliably that scientists have used it as a control when running experiments on different fats. The harsh processing may destroy some of the good essential fatty acids and antioxidants, such as lauric acid, a medium chain fatty acid believed to raise good H.D.L. cholesterol.
“If you’re going to use coconut oil, make sure you get virgin oil,” Dr. Brenna said. “And, of course, everything in moderation.”"

"It may not sound as sexy, but eating carbohydrates in moderation may be best for boosting longevity, a large new study suggests.
The study, which involved more than 15,000 Americans who were tracked for a quarter of a century, found that those who ate a low-carb diet (with less than 40 percent of daily calories coming from carbs) or a high-carb diet (with more than 70 percent of daily calories coming from carbs) were more likely to die during the study period, compared with those who ate a moderate-carb diet, with about 50 to 55 percent of their calories coming from carbs.
For example, based on the findings, the researchers estimated that from age 50, people who consumed a moderate-carb diet would have a life expectancy that was about four years longer than those who consumed a very low-carb diet (with an average life expectancy of 83 years for moderate-carb eaters versus 79 years for very low-carb eaters).
But it wasn't all bad news for people following low-carb diets. In the second part of the study, published today (Aug. 16) in the journal The Lancet Public Health, the researchers examined the effect of replacing carbs with either animal-based or plant-based proteins and fats. They found that low-carb diets that involved people consuming animal-based proteins and fats were linked with a greater risk of early death, but low-carb diets that involved people consuming plant-based proteins and fats were linked with a reduced risk of early death.

"A study published recently in the journal Scientific Reports details the process by which prolonged exposure to blue light causes a “toxic” chemical reaction in the retinal molecules and can kill photoreceptor cells.
"It’s no secret that blue light harms our vision by damaging the eye’s retina," said UT professor Ajith Karunarathne, one of the study's authors. "Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop."
He advises to avoid browsing on mobile phones or tablets in the dark. Also, newer iPhones and Androids have a "Night Shift" or “Night Mode” feature that reduces the emission of blue light from device screens in the evening hours.
“Photoreceptor cells do not regenerate in the eye. When they’re dead, they’re dead for good,” said Kasun Ratnayake, a PhD student who was involved in the study.*

The study of U.S. adults found that people who drank hot tea on a daily basis were 74 percent less likely to have glaucoma, compared to those who were not tea fans.
Experts were quick to stress that it may not be tea, itself, that wards off the eye disease. There could be something else about tea lovers that lowers their risk, said senior researcher Dr. Anne Coleman.
But the findings do raise a question that should be studied further, according to Coleman, a professor of ophthalmology at the University of California, Los Angeles.
"Interestingly," she said, "it was only hot, caffeinated tea that was associated with a lower glaucoma risk."
Decaf tea and iced tea showed no relationship to the disease. Neither did coffee, caffeinated or not.
It's hard to say why, according to Coleman. "Is there something about the lifestyle of people who drink hot tea?" she said. "Do they exercise more, for example? We don't know."
Glaucoma refers to a group of diseases where fluid builds up in the eye, creating pressure that damages the optic nerve. It's a leading cause of blindness in older adults, according to the American Academy of Ophthalmology (AAO)
Some people face a higher risk than others, the AAO says: They include blacks, people with a family history of glaucoma, and people with high blood pressure, diabetes or other conditions that affect blood circulation.
Some studies have suggested that people who drink a lot of coffee have a heightened glaucoma risk. Others have hinted that caffeine can temporarily boost pressure within the eye."

Quando eles contam seus sonhos, no entanto, as diferenças apareceram. Elas ficaram bem evidentes entre os esquizofrênicos e bipolares.
Os relatos dos primeiros, representados por grafos, apresentam menos ligações do que os demais. Eles costumam falar de forma lacônica e com pouca digressão (desvio de assunto), o que explica por que a conectividade e a quantidade de arestas dos seus grafos são menores em comparação às dos bipolares, que, por sua vez, tendem a apresentar um sintoma oposto, a logorreia.

"Salk Institute researchers report that giving mice dietary iron supplements enabled them to survive a normally lethal bacterial infection and resulted in later generations of those bacteria being less virulent. The approach, which appears in the journal Cell on August 9, 2018, demonstrates in preclinical studies that non-antibiotic-based strategies—such as nutritional interventions—can shift the relationship between the patient and pathogens away from antagonism and toward cooperation.
"Antibiotics and antimicrobials are one of the most important advances in medicine, and we definitely need to continue efforts focused on developing new classes of antimicrobials," says Associate Professor Janelle Ayres, who holds the Helen McLoraine Developmental Chair and is senior author of the new paper. "But we need to learn from history and think about other ways to treat infectious diseases. Our work suggests that instead of killing bacteria, if we promote the health of the host, we can tame the behavior of the bacteria so that they don't cause disease, and we can actually drive the evolution of less dangerous strains.""

"New research suggests the mix of microbes in our guts can either help — or hinder — weight-loss efforts.
"We started with the premise that people have different microbial make-ups, and this could influence how well they do with dieting," explains Purna Kashyap, a gastroenterologist at the Mayo Clinic in Rochester, Minn.
As part of the study, Kashyap and his collaborators tracked the progress of people who were enrolled in a lifestyle-intervention program for weight loss. The participants were advised to follow a low-calorie diet, and they were tracked closely for about three months.
"We found that people who lost at least 5 percent of their body weight had a different gut bacteria as compared to those who did not lose 5 percent of their body weight," Kashyap explains. Their findings are published in the journal Mayo Clinic Proceedings."
(...)
"The successful dieters had an increased abundance of a bacteria called Phascolarctobacterium, whereas another bacteria, Dialister, was associated with a failure to lose the weight. And, Kashyap says it's likely that there are other types of bacteria that might influence dieting as well."
Bottom line: the bacteria eat what else can't
"Probiotics that are currently on the market would not be effective. The idea is to develop a new product that includes the specific types of bacteria linked to successful dieting.
But it's not so simple to manipulate the mix of microbes in our guts. Identifying the organism — or organisms — that are thought to be beneficial is just the first step."

"According to a study, an analysis of blood samples can highlight high levels of inflammation in a patient and help predict which drugs may not be effective. Other recent studies have found a link between increased inflammation and lower success rates from treatment.
Identifying this increase up front can help predict which people may need more aggressive treatment early on.
Currently, treatment for depression involves a process of trial and error, with doctors prescribing a particular drug for periods of up to 12 weeks and monitoring patients for any improvement. If no response is seen, a new drug, or combination of drugs, is tried until one is found to be effective.
"If [patients] don't get better, they just switch drugs and then switch again with hope that one will work," said Carmine Pariante, professor of biological psychiatryat Kings College London, who developed the test and led the study."
