As many as 700 species of bacteria live on our teeth and in our mouth, and just like the microbiomes inhabiting other parts of our bodies, they change in response to diseases and other health conditions.
Some studies have shown that vitamin D supplements help fight respiratory infections, but some haven't. A new study published in The BMJ clarified the confusion, and identified a group of people that might be better able to fight off colds and flu with vitamin D supplements.
Most of us equate feeling cold with catching a virus—but we've also heard plenty of debunkers proselytizing that being cold isn't what gives you the flu.
You may not know what HTTP is exactly, but you definitely know that every single website you visit starts with it. Without the Hypertext Transfer Protocol, there'd be no easy way to view all the text, media, and data that you're able to see online. However, all communication between your browser and a website are unencrypted, which means it can be eavesdropped on.
Editor's Note: The research described in the article below has been criticized and any conclusions based off this research should be examined with a skeptical eye. The article has been edited to reflect these issues.
Rather than reaching for aspirin the next time a headache strikes, try grabbing a drink of lemonade instead. Not only can it help ease your head pain, but it can also help relieve stress, anxiety, and depression. But not just any old lemonade will do the trick—reach for the lavender lemonade.
Welcome back, my tenderfoot hackers! Hacker newbies have an inordinate fixation on password cracking. They believe that cracking the password is the only way to gain access to the target account and its privileges. If what we really want is access to a system or other resources, sometimes we can get it without a password. Good examples of this are replay attacks and MitM attacks. Neither requires us to have passwords to have access to the user's resources.
Welcome back, my nascent hackers!
Shopping: you either love it or hate it. With a tight budget, shopping can become a huge headache for even the biggest shopaholic. We've all been there, and we've all given in to our impulses and bought something we probably shouldn't have. Yet strolling through the mall doesn't have to require a strong will to keep your credit card from entering a downward spiral. You just need to keep your hands to yourself.
Admit it: when nothing's at stake other than your boss's disapproval, you don't exactly feel the urge to get working. Finding the motivation to take on a task, whether at work or home, can be a constant struggle. Though working through your laziness might seem like the best course of action, a meaner method can make more of an impact on your productivity.
Apple has Siri, Google has its Now service, and Microsoft has Cortana. All of these voice-activated services can bring you information quickly and easily without having to type anything into your smartphone. Speak and within seconds you're provided with either an answer or somewhere you can find it.
Check it out: you save more dough (ba dum bump) when you order a large pizza than with any other size. Why is this true? NPR reporter Quoctrung Bui's engineer friend pointed out that a medium pizza was twice as big as a small one, yet only cost slightly more.
Last year, The New York Times wrote that certain restaurants in Manhattan and Brooklyn banned patrons from taking photos of their meals. That means no flash photography, no standing on chairs for a better angle, not even a quick pic for your Instagram followers before the first bite. Little do these restaurants know, this ban can actually make their customers' food taste worse, so to speak.
Think eating food is as easy as putting it in your mouth? It's considerably more complicated than that. Your brain plays a big role in determining what and how you eat. Understanding how your brain interprets food choices is key to managing your eating habits.
Reading is no longer a leisure activity—it's an on-the-go activity that requires speed and less attention. That's why speed reading apps are growing in popularity. As smartphones and tablets increasingly take over the traditional book market, reading skills need to be adjusted accordingly, so you can cram in 5 pages in-between texts and emails.
How many times have you heard someone utter the phrase, "Now, let's break into groups"? From classroom discussions to workplace think tanks, gathering into groups to generate ideas is common practice. These forced get-togethers are intended to encourage creativity and unique thought, but they can actually do the opposite. More often than not, group brainstorming is annoying rather than encouraging, and these group sessions can actually be detrimental to your productivity. Getting together har...
Editor's Note: The claims by Vani Hari which were originally detailed in the article below about azodicarbonamide were unscientific in nature. This article has been updated to reflect that and provide more scientific context on the issue.
Earlier today, a meteorite flew over the Chelyabinsk region of Russia, triggering a shock wave that injured hundreds of people and caused damage to buildings and vehicles in the area. Witnesses describe seeing a bright ball of light streak through the sky followed by a loud boom as the 10-ton meteorite entered the Earth's atmosphere and exploded.
3D printing has been around for a while, but until recently it was used mostly for prototyping and research. Now, with technological advancements, it seems like everyone is using 3D printers, from crime scene investigators to garage hobbyists and hackers. Below are some of the most innovative uses people have come up with so far.
While conducting an OSINT investigation, it's important to be able to pull in information based on any clue you uncover. In particular, license plate information can turn up everywhere, from photos to live data to on your own street. You could use that data to find the VIN, see if a Tinder date has hit anyone, find out who's blocking your driveway, and so on. Skiptracer can help get the ball rolling.
You're reading this so you're probably already safely huddled up in your house or apartment, watching as the entire planet grapples with the unfolding coronavirus health crisis. But unlike some others, you're lucky enough to already have a couple of weeks of supplies and now it's just about what you can do to entertain yourself and your family as you weather the current situation.
One of the best ways to dig into a website and look for vulnerabilities is by using a proxy. By routing traffic through a proxy like Burp Suite, you can discover hidden flaws quickly, but sometimes it's a pain to turn it on and off manually. Luckily, there is a browser add-on called FoxyProxy that automates this process with a single click of a button.
The ability to shift between virtual reality and augmented reality seamlessly on one device is a dream of many AR fanatics, but the execution is usually fairly buggy or underwhelming.
Starting Nov. 1, 2018, Google got a lot tougher with Android app developers. New apps being uploaded to the Play Store already had to target Android 8.0 Oreo or higher as of August, but now, every update to existing apps has to do the same. It may seem like a simple rule, but it will have some serious repercussions.
On Friday, audio giant Bose emerged as the latest, and perhaps the most surprising company to announce that it's planning to release augmented reality smartglasses.
The incidence of tuberculosis (TB) is dropping in the US, but the World Health Organization (WHO) considers it to be epidemic in the rest of the world — there were over 10 million new cases in 2016.
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.
This fall, DC Comics fans will be treated to an augmented reality experience promoting the Justice League movie. Likewise, history buffs will be able to enjoy their own augmented reality content by way of the Terra Cotta Warriors exhibit at The Franklin Institute in Philadelphia, Pennsylvania and an in-store promotion featuring famous convicts from 19 Crimes wines.
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.
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.
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.
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...
An older man dies of Zika. A younger man who cares for him catches Zika — but doctors cannot pinpoint how the disease was transmitted. While proximity to the patient is sufficient explanation for the rest of us, for microbe hunters, it is a medical mystery. Why? Zika is not known to transmit from person-to-person casually.
Foodborne infections often occur through the contamination of equipment, food-prep tools, and unsanitary surfaces. A recent report from the Centers for Disease Control and Prevention (CDC) reminds us that breast pump parts are part of the food-delivery chain — and they can become contaminated too.
Flu vaccines can help prevent us from getting or suffering the most severe effects of the flu. But, each vaccine only protects us from three different strains of the flu. If we don't have a vaccine against all types of flu, it leaves us open for an epidemic with a flu virus we didn't expect.
For younger children, a day at the playground is not complete without some sandbox time. Long a favorite of children and parents, sandboxes could also be sheltering dangerous pathogens.
Deadly rat lungworm parasites have found their way into Florida. The parasitic worm relies on snails and rats to complete its life cycle, but don't let this nematode's name fool you. This worm can cause meningitis and death in humans who inadvertently consume snails, frogs, or crustaceans harboring the infective parasite.
Significant strides have been in the race to find antibiotics to treat superbug infections — those caused by bacteria resistant to the antibiotics used to treat them. Now, an international team of scientists has discovered a new antibiotic produced by a microbe found in Italian soil.
As summer heats up, new maps from the Centers for Disease Control and Prevention (CDC) gives us our best guess at where Zika-carrying mosquitoes could be hanging out this year in the US.
Citrus greening disease — caused by a bacteria spread by psyllid insects — is threatening to wipe out Florida's citrus crop. Researchers have identified a small protein found in a second bacteria living in the insects that helps bacteria causing citrus greening disease survive and spread. They believe the discovery could result in a spray that could potentially help save the trees from the bacterial invasion.
