Astronauts lend insight into the feasibility of humans becoming a space-faring species. They are getting closer to sending humans on extended trips into space. SpaceX is planning on sending the first humans to Mars in 2024 and they will likely soon set our sights for destinations further than that. They recently had the opportunity to interview two of the U.S. astronauts who have spent the most time in space and ask them about the feasibility of humans becoming a space-faring species.

A novel online HIV prevention program with spicy soap operas and interactive games—like a rising thermometer of sexual risk—reduced sexually transmitted infections in gay young men by 40%, reports a Northwestern Medicine study.
Groundbreaking research demonstrates proof-of-concept for using CRISPR-Cas9 genome editing technology to correct the gene mutation responsible for alpha-1 antitrypsin (AAT) deficiency, successfully making a targeted gene correction in the livers of affected mice that restored at least low levels of normal AAT. In the studies, both published in Human Gene Therapy
Researchers examine a new microscope system can image living tissue in real time and in molecular detail, without any chemicals or dyes. The system uses precisely tailored pulses of light to simultaneously image with multiple wavelengths. This enables the researchers to study concurrent processes within cells and tissue and could give cancer researchers a new tool for tracking tumor progression and physicians new technology for tissue pathology and diagnostics.
The researchers detailed the technique, called simultaneous label-free autofluorescence multi-harmonic microscopy, in the journal Nature Communications. "The way we have been removing, processing and staining tissue for diagnosing diseases have been practiced the same way for over a century.
Young adults who frequently binge drink were more likely to have certain risk factors for cardiovascular disease than non-binge drinkers, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
Anticonvulsant drugs are increasingly being used to treat low back pain, but a new study in CMAJ (Canadian Medical Association Journal) finds they are ineffective and can have adverse effects
The first major paper looking at the causes and consequences of meningitis in the UK has found that viruses are now the most common cause of meningitis in adults and a cause of substantial long-term ill health. The paper also found that the management of many patients with meningitis is sub-optimal.
Get up off of the couch: Sitting too much may kill you even if you exercise regularly. If you sit for six hours a day or more, your risk of dying early jumps 19%, compared with people who sit fewer than three hours, an American Cancer Society study suggests.
A unique bacterial strain isolated from a patient with pelvic pain may represent a promising path to treating prostate cancer with immunotherapy, according to a Northwestern Medicine study published in Nature Communications
"This is a virus transmitted by mosquitoes that circulate between birds. It can attack the nervous system of certain birds, such as blackbirds, and cause significant mortality. It was first observed in southern Africa, in Swaziland, in 1959," says Serafin Gutierrez, a virology researcher with CIRAD"S ASTRE research unit.
The U.S. Food and Drug Administration has permitted the marketing of two catheter-based devices designed to create an arteriovenous (AV) fistula in patients with chronic kidney disease in need of hemodialysis
