Dapivirine rings have previously been shown to cut HIV infections by at least 56 percent in women older than 25. Now, a study has shown that this revolutionary prevention strategy is safe to use in teenage girls, meaning it's one step closer to getting regulatory approval and being widely available. It consists of a flexible ring, worn constantly and replaced monthly, that sits on the cervix and releases the antiretroviral drug dapivirine to fight off HIV infections. This research, presented at the 9th IAS Conference on HIV Science, is the first time scientists have analyzed how usable, effective, and safe the prevention treatment is among teenage women and girls. This is pretty important, as adolescent girls and you
Dr. George Church is a real-life Dr. Frankenstein. The inventor of CRISPR and one of the minds behind the Human Genome Project is no longer content just reading and editing DNA—now he wants to make new life. In Ben Mezrich’s latest book, Wooly: The True Story of the Quest to Revive One of History’s Most Iconic Extinct Creatures, Church and his Harvard lab try to do the impossible, and clone an extinct Woolly mammoth back into existence.$17From amazonGizmodo Media Group may get a commissionMezrich, author of the books that would become the feature films 21 and The Social Network, seems to have graduated from college to a bioengineering PhD with his latest work, which is chock-full of scientific explanation detailing every aspect of the Church lab’s efforts to rewrite the DNA of an elephant
There are quite a number of approved methods of birth control that include pills, condoms, vaginal shields, diaphragms, and implants. Now, for the first time ever, a smartphone app has been certified as a method of birth control, at least in the European Union. The best part of this story is that the app was created by a Higgs Boson physicist who had worked on the Large Hadron Collider. ZME Science says that when the collider finished its first run in 2012, Elina Berglund was thrilled, but she remembers thinking, “It’s impossible to top that, " So she decided to try something different. Relying on her own personal experience, Berglund, who had been relying on a hormonal birth control implant for 10 years, decided to give it up and try an alternative method. In her research, she discove
Nevada researchers just identified the first new species of toad found anywhere in the U.S. in 50 years, and the race is already on to save it from extinction. Conservationists are preparing an emergency petition to have the Dixie Valley toad listed as an endangered species to protect it from a proposed geothermal energy project at the edge of its isolated home in Churchill County. The toads are about 2 inches long with bumpy skin mottled in green, black and brown. Their only known habitat is a spring-fed marsh covering just more than 2 square miles of federal land in the remote Dixie Valley, about 400 miles northwest of Las Vegas. The new species was discovered by University of Nevada, Reno, researcher Michelle Gordon, former UNR researcher Eric Simandle and UNR Professor C. Richard Tr...

MEDFORD, Ore. (AP) — On a frosty night in December, James Bowman was alone and overcome with exhaustion. The cannabis grower had worked hard all day processing plants at his BlueSky Gardens near Wimer, lacking the money to keep his crew on hand to provide security through the night.Arguably southern Oregon's best-known grower, the 57-year-old struggled financially to make it through the harvest. His ambitious High Hopes Farm in the Applegate, once toured by legislators as a model of medical marijuana grows, had been raided by federal agents in 2012. He'd spent two years in court to avoid a conviction, which took a toll on his pocketbook.He needed this harvest to put him back on solid financial ground. Earlier on that fateful day of Dec. 16, 2016, he had just talked to an investor he though
With the expansion of the suburbs and a push to conserve wooded areas, deer and mice populations are thriving. They provide ample blood meals for ticks and help spread the pests to new regions.Originally from the Southeast, the lone star tick, for example, is heading north; it can now be found in 1,300 counties in 39 states. The blacklegged tick, also called the deer tick, is expanding its territory, too. In a recent study, Dr. Eisen reported a nearly 45 percent increase since 1998 in the number of counties with blacklegged ticks.Thomas Mather, director of the University of Rhode Island’s TickEncounter Resource Center, said it used to get reports of three or four lone star ticks in the greater Chicago area each year. Now, it is receiving up to 15.When a tick species marches into a
The move has set off fierce debate, not just in India but around the world. Experts say the spread of such policies — despite their best intentions — could actually deter women’s progress in the workplace.The additional days off could be used to justify lower pay or increase hiring bias against women, critics say. Absences could push women out of decision-making roles and eliminate them from consideration for promotions.And these policies may play into a decades-old prejudice that menstruation makes women unfit for work.“It suggests women are uniquely handicapped in the workplace by the fact that they have periods,” said Emily Martin, vice president for workplace justice at the National Women’s Law Center.A 2012 study found that 20 percent of women experience periods painful enoug
Just a small decline in childhood measles vaccination levels can produce disproportionate negative effects both to public health and the economy, new research has revealed. Vaccines save lives. But in some regions across the US vaccination rates are declining due to bad information and poor choices, and now scientists have put together data on how badly these choices can affect us all. A team from Stanford University and Baylor College of Medicine looked into the public health and economic impact of vaccine hesitancy, "defined as a delay or refusal to accept vaccination based on personal beliefs despite availability." In other words, they ran the numbers on what even a handful of anti-vaxxers can cost the public, and those numbers ain't pretty. Using the combined measles, mumps, and rube...
