The latest Star Wars movie, Solo: A Star Wars Story, has grossed almost $350 million worldwide during its first month in theaters. This is a good opportunity to discuss how hackers can use media hype (in this case, Hollywood movie hype) to disarm an unsuspecting Windows user into inserting an evil USB stick into their computer.
Black Mirror, Netflix's technology-horror anthology, never fails to provide thought-provoking entertainment centered around emerging and futuristic technologies, and the third season's second episode, "Playtest," delves deep into the worlds of mixed, augmented, and virtual reality. While designed to leave you haunted by the end, offering a more "evil" narrative than we'll likely see in our actual future, the episode explores possibilities that aren't as far off as one might think.
You need a break from gloomy coronavirus updates. We all do. The unrelenting stream of doom and negative news is both helpful in terms of keeping ourselves and our families safe, but it also has the unfortunate effect of increasing our anxiety. When will this end? How bad will it get? Is there reason to be hopeful?
One of the scariest things about the COVID-19 virus is that you can show no symptoms but still be infected (and contagious). Naturally, we all want to know whether we're carrying the new coronavirus, but if you're showing signs of COVID-19, how can you be tested to know for sure? Websites are popping up to help with that, screening for symptoms, and directing you to a testing site if needed.
In a stunning end-of-year twist to the Magic Leap versus Nreal legal saga, the China-based startup is now filing a motion against Magic Leap.
Augmented reality startup Nreal was a hit at this month's CES event, with some even calling the device a worthy challenger to the Magic Leap One.
Apple often cites its tight integration of hardware and software for its success. Startup Illumix is looking to do the same thing for AR gaming by building an AR platform for its apps.
Andre was enjoying the carefree life of a 12-year-old with his friends, riding his bike and playing sports, like all kids that age. Schoolwork wasn't hard for him, and his grades showed that.
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.
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.
Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...
Once we recover from the respiratory infection pneumonia, our lungs are better equipped to deal with the next infection — thanks to some special cells that take up residence there.
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.
Twelve-year old Rory Staunton took a dive for a basketball during gym class and came up with a cut on his arm. The school nurse applied a couple of band-aids, without cleaning the cut, and off he went. In approximately three days, hospital physicians told his parents there was nothing else that they could do for their son; he was dead.
With a death rate of one in five, sepsis is a fast-moving medical nightmare. New testing methods might improve your odds of survival if this infection ever hits you.
Sex makes the world go 'round, and when it does, so does gonorrhea. Finally some good news on the growing menace of drug-resistant gonorrhea — a large, long-term study shows a vaccine may work in reducing the incidence of an increasingly dangerous infection.
The de Blasio Administration of New York City has announced that the NYU Tandon School of Engineering will be hosting the country's first publicly funded VR/AR facility.
The search is on to find antibiotics that will work against superbugs — bacteria that are rapidly becoming resistant to many drugs in our antibiotic arsenal.
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.
The possibility of severe tickborne illness is increasing as an aggressive tick from the American southeast moves up the Atlantic Coast.
Drug-resistant bacteria have made curing some infections challenging, if not nearly impossible. By 2050, it's estimated that 10 million people will be dying annually from infections with antibiotic-resistant organisms.
Have you ever had a burning sensation when you urinate? Low fever, back pain, and maybe cloudy urine? Male or female, it could have been a urinary tract infection. If it lasted long enough, the chances are good you went to the doctor for help. For about 20% of women, standard testing for a UTI does not reveal the presence of infection-causing bacteria, even though bacteria may be causing their symptoms. Well, a new test may provide better answers.
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.
The ability of one microbe to adapt is giving it a whole new career as a sexually transmitted disease. Usually content with the back of the throat and nose of those who carry it, the dangerous pathogen Neisseria meningitidis has adapted to cause an illness that looks a lot like gonorrhea.
Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.
In the ongoing search to find better ways to use antibiotics, an extract made from maple syrup has some surprisingly important medical benefits.
Viral infections have been the focus of attention in the development of autoimmune diseases—diseases where the body's immune system reacts to the body's own cells—because they trigger the immune system into action.
Two viral liver diseases could help us find the path toward the cause of Parkinson's disease. Researchers from the University of Oxford and UCL Institute of Neurology in London have reported an association between hepatitis B and C infections and an increased risk of Parkinson's disease. Their findings were published early online in the journal Neurology.
To keep fungal pathogens at bay in their crowded homes, wood ants mix potions to create powerful protection for their nest and their young.
Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.
Even as health authorities describe the symptoms of Zika infection in the general population as mild, a new surveillance study finds serious side effects are more common, and serious, than previously thought.
By looking for the mechanism that allows influenza A to invade lung cells, scientists also discovered a treatment that might block the virus from taking hold there.
A group of researchers from Stanford University and Princeton University has put together the largest RGB-D video dataset to date with over 1,500 scans of over 700 different locations across the world, for a total of 2.5 million views.
As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.
A rose by any other name may smell as sweet, but one annoying invasive weed may hold the answer to treating the superbug MRSA. Researchers from Emory University have found that the red berries of the Brazilian peppertree contain a compound that turns off a gene vital to the drug-resistance process.
