‘Flying Bum’ edges out of hangar before debut flight

The Airlander 10, known in Britain as 'the flying bum' because of its unique structure, has slowly edged its way out of a hangar in central England ahead of its debut flight as a civilian aircraft. Purchased by UK-based aviation company Hybrid Air Vehicles in 2013, the 302-foot (92 meters) helium-filled airship was originally developed for the U.S. Army as a spy aircraft to hover over war zones for weeks using only a fraction of the fuel needed by conventional aircraft.

Spiders and scorpions join fight against superbugs

Over-prescription and over-use in farming of antibiotics has given rise to so-called 'superbugs', multi-drug resistant infections that can evade even the medicines designed to kill them. Experts have warned since the 1990s that lethal superbugs were on the horizon, but few drugmakers have attempted to develop drugs against them.

Almost All Lice Are Now Resistant to Over-the-Counter Treatment

The vast majority of head lice in the United States are now resistant to most over-the-counter treatments, meaning that it's now especially difficult to vanquish the tiny blood-sucking parasites, a new study finds. Researchers found that head lice (Pediculus humanus capitis) in 42 of the 48 states studied carry an average of three genetic mutations that make these bugs impervious to popular over-the-counter anti-lice remedies. Moreover, a detailed analysis showed that 98.3 percent of the genes involved in these mutations were, in fact, mutated in a way that helped the lice survive the most popular treatments, the researchers found.

High Numbers? 1 in 8 US Adults Smokes Pot

The percentage of Americans who say they currently smoke marijuana has nearly doubled since 2013, a new survey finds. Thirteen percent of adults in the U.S. now say they currently smoke pot — up from 7 percent in 2013, according to the new Gallup poll. The percentage of Americans who said they had ever tried marijuana also increased since 2013.

3 Human Chimeras That Already Exist

For example, in 2002, news outlets reported the story of a woman named Karen Keegan, who needed a kidney transplant and underwent genetic testing along with her family, to see if a family member could donate one to her. The mystery was solved when doctors discovered that Keegan was a chimera — the set of DNA in her blood cells was different from that in the other tissues in her body. A person can also be a chimera if he or she undergoes a bone marrow transplant.

Michael Phelps' Weird Bruises: Does Cupping Therapy Really Work?

Several Olympic athletes, including swimmer Michael Phelps, have appeared in Rio with odd-looking circular marks on their bodies. Although many athletes say they've experienced benefits from the therapy, there are few rigorous scientific studies on the topic, and it's unclear if the treatments' perceived benefits could be due to the placebo effect, experts said. "I don't think the science of whether it works is really solved," said Dr. Brent Bauer, director of the Mayo Clinic Complementary and Integrative Medicine Program.

Beyond 'Pokémon Go': Future Games Could Interact with Real Objects

The augmented-reality game "Pokémon Go" may be the hottest thing in mobile gaming right now, but new advances in computer science could give players an even more realistic experience in the future, according to a new study. A new imaging technique called Interactive Dynamic Video can take pictures of real objects and quickly create video simulations that people, or 3D models, can virtually interact with, the researchers said. The popularity of this game follows a decades-long trend of computer-generated imagery weaving its way into movies and TV shows.

Friends with Benefits? Cannibalism Not All Bad for Male Praying Mantis

The new research quantifies some of the ways in which the consumption of a male mantis could help produce more offspring with his genes. "What we see is a very clear conflict of interest between the male and the female," study co-author William Brown, a biologist at the State University of New York at Fredonia, told Live Science. Radioisotope labeling, feeding the insects amino acids containing distinctive variants of atoms, allowed researchers to track the transfer of nutrients from male to female to eggs.
