Imagine walking up to enter a live event — but instead of pulling out a physical or mobile ticket to get admitted — you pull out your smartphone which lets out an ultrasonic sound tailored for you that lets you into the event.
Bone loss and belly fat may no longer be certain fates of menopause, thanks to new research from an international team of scientists.
Tesla hopes high-level personnel changes will help it gain an edge in neural network knowhow for its models' self-drive features, following the replacement of its Autopilot chief and the appointment of a recent Stanford grad to head its AI and Autopilot vision research.
There are a lot of exciting improvements in store for Siri in iOS 11. Apple showed off some of the highlights at WWDC, but there are five changes in particular that you don't want to miss.
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.
Stakeholders in the driverless industry are anxiously awaiting changes the US Department of Transportation (DOT) is making to self-driving vehicle guidelines.
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.
On April 7, 2017, residents in Dallas, Texas, woke to the sound of emergency sirens blaring all over the city. No one could shut them off, and after repeated efforts to contain the situation, the city had to shut down the entire system. While the media reported a sophisticated computer hack was responsible, the truth was much less high-tech.
We fight cancer in a variety of ways, but no matter whether drugs, biologics, or our immune cells are part of the battle, they can do a better job fighting back cancer if we can help them find the tumors.
Bioluminescence — the ability of an organism to produce and emit light — is nature's light show. Plants, insects, fish, and bacteria do it, and scientists understand how. Until now, though, we didn't know how fungi glow.
Water makes up about 60% of your body weight. Whether you like it plain, flavored, bubbly, or in beverages or food, we all need water daily to avoid dehydration and stay healthy. For communities in need of clean drinking water, new research using bacteria may offer a simplified, lower-cost method for boosting potable water supplies.
A disease called "citrus greening" has devastated and permanently altered citrus production in the United States, but a vaccine that could protect orange trees may be part of a winning strategy to beat the bacteria that is killing the trees.
While at work, you notice your gloves changing color, and you know immediately that you've come in contact with dangerous chemicals. Bandages on a patient signal the presence of unseen, drug-resistant microbes. These are ideas that might have once seemed futuristic but are becoming a reality as researchers move forward with technology to use living bacteria in cloth to detect pathogens, pollutants, and particulates that endanger our lives.
If you use the Google Assistant on your Android device, you can easily send a text message to any one of your contacts. But even though that same Assistant is powering the Google Home, you can't use the smart speaker to accomplish the same task — at least, not without some tinkering.
Termite poop and biofuels — what's the connection? New research into termites' intestinal comings and goings describes a process that may speed the development and lower the cost of fuels made from plant matter.
The sun-drenched people of Phoenix can now sign up to ride in an automated car, for free, courtesy of Waymo. The Alphabet affiliate announced its "early ride program," which will (hopefully) demonstrate how self-driving cars will fit into people's everyday lives. Highlighting a challenge Nissan CEO Carlos Ghosn has spoken about that faces the driverless industry.
Well, well, well. Uber, we knew you were investing a ton of money into creating self-driving taxis and flying cars, but what we didn't know is that you were already testing out your driverless vehicles on the streets of New York City.
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.
As summer mosquito season approaches, researchers are warning people with previous exposure to West Nile virus to take extra precautions against Zika. A new study found that animals with antibodies to West Nile in their blood have more dangerous infections with Zika than they would normally.
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.
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.
The squiggly guys in this article's cover image are Propionibacterium acnes. These bacteria live in low-oxygen conditions at the base of hair follicles all over your body. They mind their own business, eating cellular debris and sebum, the oily stuff secreted by sebaceous glands that help keep things moisturized. Everybody has P. acnes bacteria—which are commonly blamed for causing acne—but researchers took a bigger view and discovered P. acnes may also play a part in keeping your skin clear.
An advance in the race to stop birth defects caused by Zika-infected mothers has been made by a team of researchers from Rensselaer Polytechnic Institute in Troy, New York. They have identified the process Zika uses to gain entry into the placenta, and published their findings in the journal Biochemistry.
Within the coming months, software startup Neurable plans to introduce the next paradigm in virtual and augmented reality: the brain–computer interface (BCI).
Phase 2 of a Zika vaccine trial began in the United States this week, along with Central and South America.
The search for a cancer treatment that selectively finds and kills only the cancerous cells has just made a giant leap forward.
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.
In the past, infection with human immunodeficiency virus (HIV) commonly led to dementia as the virus made its way to the brain. Even in effectively treated people, HIV can hide out and replicate in places like the brain, where it's tough to detect. That's why it's very concerning that half of all HIV-infected patients still report cognitive problems.
Hospitals are places we go to get well, and we don't expect to get sick or sicker there. But a study from researchers at the Cleveland Clinic, Case Western Reserve University School of Medicine, and Cleveland VA Medical Center in Ohio found that hospital floors in patient rooms were frequently contaminated with healthcare-associated pathogens—often dangerous multi-drug resistant bacteria.
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 new study confirms that antibiotics can prevent surgical intervention if your child's appendix becomes inflamed, potentially saving his or her life.
While music may not technically be a "universe language," it is the one language listened to by all. There are over 1,500 music genres today—rap, classical, rock, jazz, trap, hip-hop, house, new wave, vaperwave, charred death, nintendocore... and the list goes on. And if you're like most people, you now probably listen to the majority of your music on your phone.
The pathogen referred to as a "nightmare bacteria" is quietly adapting and spreading faster than anticipated.
Although their effectiveness is waning, antibiotics remain a front-line defense against many infections. However, new science reveals using the wrong antibiotic for an infection could makes things much worse.
In the summer of 1976, 4,000 American Legionnaires descended upon the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania, for a four-day convention. Several days later, many of the attendees experienced symptoms of severe pneumonia. By the beginning of August, 22 people had died. The Centers for Disease Control and Prevention (CDC) estimate that about 180 people were sickened and 29 people died before this mysterious outbreak burnt out.
Over 1.2 million people in the US are infected with human immunodeficiency virus (HIV)—and one out of eight of them don't know it. Even after decades of intense research into the virus, there's still no cure for it. One of the big problems is that the virus hides out in certain cells of the body, resisting treatments that kill it.
A young child becomes very thirsty very often and seems tired all the time. A visit to the pediatrician determines she has type 1 diabetes. The onset of type 1 diabetes may seem sudden, and it can be, but the disease may actually have been triggered by common childhood viruses years earlier.
The new Google Assistant is only officially available on three platforms—newer Android phones (Pixels and those running Marshmallow and Nougat), the Google Allo app, and Google Home. However, most of the Assistant's basic functionality is also bundled into the Google app for Android and iOS, which used to go by the name Google Now, but is now referred to only as Screen Search or your Google app's Feed.
No one ever said you had to be a culturally-relevant pun for Halloween, you know—or a scantily-dressed version of the inmates from Orange is the New Black.
