News: This Genetic Defect Could Be Why Typhoid Mary Never Got Typhoid Fever

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...

Put Down the Ointment: Topical Antibacterials Totally Disrupt Your Skin Microbiome

The next time you suffer a cut or abrasion, think twice before you reach for the Neosporin. It's time, and mom, tested — you get a cut, you wash it carefully, then apply some triple-threat antimicrobial ointment. You may or may not slap on a band-aid. We won't cover it here, but so that you know, covering the wound with a sterile dressing or band-aid is a good idea.

NR50: The Influencers to Watch in Augmented & Mixed Reality

When building anything of a social nature, be it a local roller derby or softball team, a club dance night for chiptune, or building new technology markets, the community around those ideas are an important factor in helping these things not only come into existence but to grow into something that enlightens everyone involved. The community around an idea can actually make or break these new ventures — and this applies to augmented and mixed reality as well.

News: Antibiotics Could Be Contributing to Dramatic Drop in Bee Populations

Add antibiotics to the possible list of culprits responsible for honeybee decline around the world. While it may come as a surprise, antibiotics are commonly mixed into feed used by commercial beekeepers to maintain their hives. In a recent study published in PLOS Biology, researchers from the University of Texas at Austin found antibiotics used to treat honeybees may be a contributing factor in individual bee death and colony collapse.

How To: Sew a dress shirt collar

By using sewing pattern Simplicity 4670, the author of this tutorial video takes you through the steps needed to produce a great shirt collar. First you should attach interfacing to one piece of the shirt collar. Here you will be using fusible interfacing and taking the facing to the shirt collar iron the interfacing to the wrong side of the fabric. Sew a guide line that is 5/8ths of an inch wide along the notched edge of the shirt collar's facing piece. At the dot markings of the collar clip...

News: Starve E Coli of Copper to Cure Aggressive UTIs

Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.

News: Probiotics Could Cut Sepsis in Infants for Just $1 a Day

Bacteria, viruses and other germs sometimes set off the immune system to overreact, producing a severe condition called sepsis. Sepsis is so dangerous that it is the leading cause of death of children across the world, killing a million kids every year, mostly in developing countries. Probiotic bacteria might be able to prevent sepsis and infections, but no large research studies have been done to find out whether that actually works. Until now.

News: Unexpected Microbial Life in Glacial Clay Could Offer Antibiotic Solutions

For as long as 14,000 years, the First Nations people of the Heitsuk Nation have made their home along the Central Coast of the Canadian province of British Columbia. Among the territory's inlets, islands, rivers, and valleys lie a clay deposit on the north side of Kisameet Bay, near King Island. For as long as most can remember, the tribe has used the clay as medicine. Now science says microbes that live in that clay may have important antibacterial properties.

News: You Don't Need Antibiotics for Pink Eye

Crusty, itchy, red eyes? There is a decent chance you could have conjunctivitis, or pink eye, an infection of the thin lining around the eye and the eyelid, caused by bacteria, an allergen, virus, or even your contact lenses. Whatever the cause — you call up your doctor to get a prescription to clear it up, right? Not really.

News: How Parental Choice Not to Vaccinate Kids Starts and Spreads Pertussis Outbreaks

It's not always easy to get to the root of an infection outbreak. Epidemiologists study infected people, contacts, and carefully examine where the infections happened and when. In the case of a 2012 outbreak of pertussis — whooping cough — in Oregon, scientists just published an analysis of how vaccination status affected when a child became infected during the outbreak.

NR50: Next Reality's 50 People to Watch: Timoni West

If you're a developer in the augmented and mixed reality space, there's a high probability that you're intimately familiar with the 3D application and game engine Unity. In May, at VisionSummit 2017, Microsoft announced that 91% of all HoloLens applications have been made with the software. But there's a section of Unity that you may not be familiar with, which has become very important to augmented, mixed, and virtual reality (known collectively as XR, for "extended reality") — Unity Labs.
