Scientists develop slippery toilet coating to stop poo sticking

Spray-on surface could prevent bacteria building up and reduce household water use The toilet brush need never leave its holder again. Scientists have created a super-slippery coating that helps usher excrement on its way without leaving traces behind. The spray-on coating, which is slipperier than Teflon, reduces adhesion of even tenacious faeces by up to 90%, tests suggest, so far less water is needed to flush them away and leave the toilet clean. Researchers at Penn State University believe the coating could slash Writing in the journal Nature Sustainability, Wong, who has co-founded a company to sell the coating, describes how all of the comparison surfaces displayed extreme stickiness to the faeces, while the Less coating appeared to shed its …

Scientists discover first new HIV strain in nearly two decades

(CNN)For the first time in 19 years, a team of scientists has detected a new strain of HIV. Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said current treatments for HIV are effective against this strain and others. However, identifying a new strain provides a more complete map of how HIV evolves. “There’s no reason to panic or even to worry about it a little bit,” Fauci said. “Not a lot of people are infected with this. This is an outlier.” For scientists to be able to declare that this was a new subtype, three cases of it must be detected independently. The first two were found in the Democratic Republic of Congo in the …

You might want to change the time of day you take your blood pressure medicine

(CNN)You may want to take your blood pressure medicine at bedtime rather than when you get up in the morning, according to a study published Tuesday in the European Heart Journal. Compared to those who took their medicine in the morning, the people who took their medicine at night had nearly half the risk of dying from heart problems and nearly half the risk of having heart attack, stroke, heart failure, myocardial infarction or of needing a procedure to unblock their arteries.

Rabbits may hold key to solving mystery of human female orgasm

Study suggests climax may be an evolutionary hangover but crucial questions remain A possible explanation for one of biologys greatest mysteries, the female orgasm, has been bolstered by research showing that rabbits given antidepressants release fewer eggs during sex. The human female orgasm has long proved curious, having no obvious purpose besides being pleasurable. The scientists behind the study have previously proposed it might have its evolutionary roots in a reflex linked to the release of eggs during sex a mechanism that exists today in several animal species, including rabbits. Since humans have spontaneous ovulation, the theory goes that female orgasm may be an evolutionary hangover. They say the new experiment supports the idea. We know there is a reflex …

Seeking relief from nicotine addiction, some e-cigarette users turn to smoking

(CNN)Lucas McClain started smoking cigarettes in high school but switched to vaping after he heard e-cigarettes were a safer alternative. Even though McClain knows the dangers of cigarettes — lung cancer runs in his family — he thinks it might be easier to kick cigarettes than his Juul. Plus, his mom keeps warning him about the mysterious vaping-related illnesses that have sickened hundreds across the country. So last month, McClain bought his first pack of cigarettes in years. Then he tweeted about it. “Bought a juul to quit smoking cigarettes,” he wrote, “now I’m smoking cigarettes to quit the juul.” He ended with this hashtag: #circleoflife.

Facebook debuts vaccine pop-up windows to stop the spread of misinformation

(CNN)A new feature is rolling out on Facebook and Instagram to combat the spread of anti-vaccine misinformation. How vaccines stop diseases like measles “We know that parents often turn to social media to access health information and connect with other parents, and it can be difficult to determine what is accurate and who the credible sources of information are,” CDC spokeswoman Kristen Nordlund said in an email on Wednesday.

This launch comes at the same time a measles outbreak has hit the United States, reaching more than 1,200 confirmed cases across 31 states since the beginning of the year. Outbreaks have also …

Teenage boy goes blind after existing on Pringles, white bread and french fries

Testosterone can enhance libido in postmenopausal women, new research says

(CNN)Doctors have long mulled over using low doses of the hormone testosterone as a way to improve sexual function in some women, but evidence on its safety and efficacy has been somewhat lacking — until now. “Further research is needed to clarify the effects of testosterone treatment in premenopausal women and the effects on musculoskeletal and cognitive health and long-term safety,” they wrote. The researchers found that, compared with a placebo or another hormone treatment such as estrogen, taking testosterone for at least 12 weeks significantly increased sexual desire, pleasure, arousal, orgasm, responsiveness, self-image and the frequency of satisfactory sexual events in postmenopausal women. The data from those previous reports also showed that testosterone significantly reduced reported sexual concerns and …

Why Kevin Durant’s Achilles Tendon Was His Achilles’ Heel

You can watch Kevin Durant tear up his Achilles tendon in gif form if you want. It’s all over the internet—the Golden State Warriors’ scoring machine bouncing the ball between his legs in an attempt to get past Serge Ibaka of the Toronto Raptors, pushing off his right leg and pivoting on his left, showing Ibaka his back. Then when Durant puts his weight back down after the turn, something’s wrong. He has felt a pop, like getting hit in the back of the leg. Durant limps off the court. He’d later report on Instagram that, yes, his right Achilles tendon had ruptured, that he had gotten surgery to repair it, and that he wouldn’t be playing basketball for a …

Sleeping with lights on and weight gain in women linked in new study

(CNN)Keeping a lot of light on while you snooze — such as from a television or bright nightlight — has been linked with an increased risk of weight gain and obesity. Obesity means having too much body fat and overweight means weighing too much, according to the US National Library of Medicine. Both overweight and obesity are based on your body mass index but “obese” generally means having a much higher BMI. “We are in the middle of an obesity epidemic in the United States and the things that we usually think about for obesity prevention are hard for people to do — eat a better diet, get more exercise — and we don’t seem to be making a dent,” …
