Scientists know that bacteria create their own energy, get nutrients to run their cellular processes, and multiply. But, bacteria haven't been shown to respond to external mechanical stimulation or signals in a way that's similar to how our bodies respond to touch, until now.
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.
For about a million Americans each year, a joint replacement brings relief from pain and restored mobility. But, 5–10% of those people have to endure another surgery within seven years, and most of those are due to an infection in their new joint. If doctors could treat infections more effectively, patients could avoid a second surgery, more pain, and another rehabilitation.
At Build 2017, the annual developer's conference, Microsoft featured a Windows Mixed Reality Academy. This class was designed to get a developer started creating Mixed Reality experiences quickly. For those of us already developing for the Microsoft HoloLens, while the class — which is now available on the Microsoft website — did offer our first real chance to work with the new Acer HMD, there was not much depth.
As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists believe that gut bacteria may have a role in initiating the abnormal immune response. Now, a team of researchers from Boston has figured out how that might occur.
Cancer cells do a pretty good job of flying under the radar of our immune system. They don't raise the alarm bells signaling they are a foreign invader the way viruses do. That might be something scientists can change, though.
Malaria is a massive worldwide health problem. The Centers for Disease Control and Prevention estimate that 212 million cases of malaria occurred worldwide in 2015 and 429,000 of the infected people died.
The community of bacteria that lives in our gut has a lot to tell us. It can give clues to what we eat, the environment we live in, and diseases and disorders we may have. Now, scientists have linked these bacterial species to how we feel. A new research study found an association between women's gut bacteria and their emotions.
Even though HIV rates declined 18% between 2008 and 2014, 1.1 million people in the US are living with the infection. Part of that is because HIV is treatable, but not curable.
Over the past week, companies took a variety of approaches to investing in augmented reality. Lampix is backing its own effort to build an ecosystem for augmented reality platforms. Nokia and Xiaomi are teaming up on numerous fronts, potentially including augmented reality.
Montezuma's revenge, the runs, the trots, or just diarrhea — everyone gets it sooner or later. What exactly is diarrhea good for, if anything?
By connecting the dots between theory and real-life effect, two new studies offer more proof that neonicotinoid insecticides are causing extensive damage to honeybee colonies.
A new medical development is going to change the way many of us look at getting the flu vaccine. A painless flu vaccine skin patch is making needles and vials a thing of the past. Researchers from the Georgia Institute of Technology and Emory University have shown that a flu vaccine can be administered safely and comfortably with this new patch, which delivers the vaccine through a matrix of tiny dissolving microneedles.
Bed bugs are parasites not yet known to spread disease — but they cause plenty of irritation. As scientists and landlords search for new ways to deal with the pests, a new study examines how we can deter bed bugs without so many chemicals.
People who have heart disease get shingles more often than others, and the reason has eluded scientists since they first discovered the link. A new study has found a connection, and it lies in a defective white cell with a sweet tooth.
Most people are familiar with the decline of honeybee colonies around the world. Among other threats, Colony Collapse Disorder (CCD) is eroding the capability of honeybees to maintain their hives and provide their services to human farmers.
There is an Indian story called the Legend of Paal Paysam, and while it doesn't seem like it at first, it has a lot to say about what motivated Paul Travers in the augmented reality space.
Walsh, a new community under construction on 7,200 acres of former ranch land near Fort Worth, Texas, will one day contain 15,000 homes.
HIV infections persist despite treatment that successfully decreases viral blood levels to the point where doctors can't detect the virus. But that doesn't mean the person is cured. The virus hides in the body, not replicating, just waiting for a chance to jump out of the shadows and reemerge.
Alzheimer's disease — an irreversible, progressive brain disorder — is the sixth leading cause of death in the US and more than afflicts 5 million Americans. As if those numbers aren't scary enough, the Centers for Disease Control and Prevention expect that number to nearly triple by 2050.
Even before we are born, our immune system is hard at work. New research shows how the developing fetal immune system takes advantage of the time and opportunity of gestation — in the presence of mom's cells and tissues — to develop a sense of self.
Zika is a threat to unborn babies — the virus can cause neurological damage if it infects a mother during pregnancy. But as with many things, our solutions to the problem aren't always all that much better than the problem itself.
We know that healthcare-related facilities can be fertile ground for antibiotic-resistant bacteria, but recent research suggests your produce aisle might be too.
Intense exercise can cause problems with our digestive tract. It even has a name — "Exercise-induced Gastrointestinal Syndrome." Simply put, strenuous exercise can damage the gut and let the bacteria that reside there potentially pass into the bloodstream.
Several recent research studies have pointed to the importance of the microbes that live in our gut to many aspects of our health. A recent finding shows how bacteria that penetrate the mucus lining of the colon could play a significant role in diabetes.
Many developers, myself included, use Unity for 3D application development as well as making games. There are many that mistakenly believe Unity to be a game engine. And that, of course, is how it started. But we now live in a world where our applications have a new level of depth.
Listeria monocytogenes bacteria don't play fair. Healthy people can usually handle the food-borne infection, but the bacterial infection hits pregnant women, fetuses and cancer patients very hard. Interestingly, a new study found that other bacteria may help prevent Listeria infections in those people.
The possibility of severe tickborne illness is increasing as an aggressive tick from the American southeast moves up the Atlantic Coast.
Most of us have already had an encounter with the Epstein-Barr virus, or EBV, for short. As part of the herpes family, it's one of the most common disease-causing viruses in humans. We get the disease with (or without) some nasty symptoms, then we recover. However, EBV stays in our body after the illness has ended, and it's one of the few viruses known to cause cancer.
The problem with HIV is that it attacks and kills the very cells of the immune system that are supposed to protect us from infections — white blood cells. But a new technique, developed by scientists at The Scripps Research Institute (TSRI) in La Jolla, California, offers a distinct HIV-killing advantage.
An innovative new wound dressing has been developed by a research team at Lodz University of Technology in Poland that uses crustacean shells to create a bandage that packs an antimicrobial punch — and even more potential to help solve a global problem.
Even though the Ebola virus was discovered as recently as 1976, over 30,000 people have been infected since, and half have died a horrible death. Since there's no way to cure the infection, the world desperately needs a way to prevent it — and the five similar viruses in its family, the ebolaviruses.
We've worked hard to reduce the flow of toxic chemicals into our waterways, which means no more DDT and other bad actors to pollute or destroy wildlife and our health. But one observation has been plaguing scientists for decades: Why are large quantities of one toxic chemical still found in the world's oceans?
The evolution of our infection-fighting systems may have something to teach modern scientists. That's what a group from the University of Granada in Spain found when they studied a protein that's been around for over four billion years. Their work, by senior author José Sánchez-Ruiz and colleagues in the Department of Physical Chemistry, was published in the journal Cell Reports.
Being infected with HIV means a lifetime of antiviral therapy. We can control the infection with those drugs, but we haven't been able to cure people by ridding the body completely of the virus. But thanks to a new study published in Molecular Therapy by scientists at the Lewis Katz School of Medicine (LKSOM) at Temple University and the University of Pittsburgh, all that may change.
Globes used to be standard in households, usurped in many ways by modern mobile and desktop applications. But one company believes they can upgrade the globe for the 21st century.
Devastating and deadly, land mines are a persistent threat in many areas of the world. Funding to clear regions of land mines has been decreasing, but new research may offer a less dangerous method of locating hidden, underground explosives by using glowing bacteria.
On October 17, 1943, a story in the New York Herald Tribune read "Many laymen — husbands, wives, parents, brothers, sisters, friends — beg Dr. Keefer for penicillin," according to the American Chemical Society. Dr. Chester Keefer of Boston was responsible for rationing the new miracle drug, penicillin.
Our quest to find new antibiotics has taken a turn — a turn down the road, that is. A team of scientists from the University of Oklahoma is scooping up roadkill and searching for bacteria on them that might yield the world's next antibiotic.
Sophisticated hackers have been exploiting vulnerabilities in Chrome and Firefox to trick even the most careful internet users into logging into fake domains for sites like Apple, Google, and Amazon.
