Germ transplant helps women with tough-to-treat vaginal infections

Posted by in category: biotech/medical

Bacterial vaginosis is a common infection in women that’s usually easily treated with antibiotics. But for those who develop recurrent infections, treatment options have been limited.

Now, Israeli researchers report they were able to put recurrent infections into remission in four out of five women who received a “vaginal microbiome transplant.” The transplant consisted of healthy bacteria collected from the vaginal fluid of donors without the condition, the researchers explained.

“Bacterial vaginosis, while not life-risking, is an exceedingly common female disorder that bears a severe toll on women’s lives, including severe discomfort, reduced , problems in , social segregation and a variety of risks of developing infectious gynecological and obstetric complications,” said the study’s senior author, Dr. Eran Elinav.

Here’s How We Could Feed a Million People on Mars

Posted by in categories: food, space, sustainability

If we want to colonize Mars, we’re going to need to figure out a way to feed ourselves there, and continuously sending food to the Red Planet isn’t a sustainable plan.

But now, a team of researchers thinks it’s figured out a way to produce enough food on Mars to feed a million people — and they say their plan to make Martian colonists self-sufficient would take just a hundred years to implement.

Elon Musk: Teslas Will Soon Make “Fart” and “Goat” Noises

Posted by in categories: Elon Musk, humor, transportation

Tesla CEO Elon Musk has a weak spot for potty humor.

First, the carmaker introduced a “fart app” for its electric vehicles, which generates rude bathroom sounds.

Now, Musk says Teslas will soon be getting “customized horn and movement sounds,”— including “goats” and “farts,” according to a emoji-laden Sunday tweet.

A DNA Switch for Whole-body Regeneration

Posted by in categories: biotech/medical, life extension

When it comes to regeneration, some animals are capable of amazing feats — if you cut the leg off a salamander, it will grow back. When threatened, some geckos drop their tails as a distraction, and regrow them later.

Other animals take the process even further. Planarian worms, jellyfish, and sea anemones can actually regenerate their entire bodies after being cut in half.

Led by Assistant Professor of Organismic and Evolutionary Biology Mansi Srivastava, a team of researchers is shedding new light on how animals pull off the feat, and uncovered a number of DNA switches that appear to control genes for whole-body regeneration. The study is described in a March 15 paper in Science.

Complex energies, quantum symmetries

Posted by in category: quantum physics

In a certain sense, physics is the study of the universe’s symmetries. Physicists strive to understand how systems and symmetries change under various transformations.

New research from Washington University in St. Louis realizes one of the first parity-time (PT) symmetric , allowing scientists to observe how that kind of symmetry—and the act of breaking of it—leads to previously unexplored phenomena. The work from the laboratory of Kater Murch, associate professor of physics in Arts & Sciences, is published Oct. 7 in the journal Nature Physics.

Other experiments have demonstrated PT symmetry in such as coupled pendulums or optical devices, but this new work in Murch’s lab, along with experiments in China by Yang Wu et al., reported in Science this May, provides the first experimental realization of a PT-symmetric quantum system.

From ‘weirdo’ PhD stargazer to Nobel Physics laureate

Posted by in categories: physics, space

As a student astronomer scanning the skies with homemade instruments a quarter of a century ago, Didier Queloz spent months doubting the data that led him to an inescapable conclusion: he’d just discovered the first planet outside Earth’s solar system.

The Swiss scientist had spent much of his PhD research refining techniques to detect so-called exoplanets, which until one fateful night in October 1995 had previously only existed in the realm of science fiction.

Queloz and his colleague Michel Mayor, who on Tuesday were awarded the Nobel Prize for Physics for their pioneering work, had already overcome a number of obstacles in their galaxy-wide search.
