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.
Despite mounting scientific evidence that viruses can cause changes in learning and memory, the reasons have remained elusive.
Staphylococcus aureus is a widespread bacteria — about a third of us have it on our body right now — usually in our nose or on our skin. And it probably isn't causing an infection. But, about 1% of people who have Staphylococcus aureus present have a type that is resistant to the antibiotic methicillin.
Heart disease is the leading cause of death of men and women in the US. Over half a million Americans die from it annually. Atherosclerosis — a build up of plaque in the arteries — is a common feature of heart disease and can be caused by smoking, fats and cholesterol in the blood, diabetes, and high blood pressure.
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.
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.
A new study casts real suspicion on the possibility of life on Mars. Why? It seems the surface of the planet may be downright uninhabitable for microbial life as we know it.
Add breathing in your house as another possible danger to your health. If your home is sick, it's possible you could get sick too.
Is technology making us disconnected? Findings from a study conducted by YouGov hint that — for millennials — the answer is yes. The research found that nearly one in five US teens prefers to video chat their friends rather than spend time with them face-to-face.
Sherif Marakby has returned to Ford as the VP of AVs & Electrification after a brief stint with Uber. Marakby's VP title will be effective June 12.
As researchers from Yale searched our environment for compounds to aid in the battle against drug-resistant bacteria, they got an unlikely assist from ticks.
Pertussis, or whooping cough, is a highly contagious disease that can be life-threatening for young children. New research backs a recommendation that all pregnant women receive a pertussis booster with each pregnancy, as it can help their infants fight off the infection.
As it turns out, your Android apps are pairing together to share your data without asking for your permission first. Researchers from Virginia Tech developed a tool called DIALDroid to monitor exchanges of data between Android apps over the last three years, and what they've found is quite alarming.
Most people know atopic dermatitis by its common name, eczema—that dry, flaky skin that itches incessantly. Along with the scratching comes frequent skin infections, often with Staphylococcus aureus.
It feels like someone reached into your chest and squeezed. Your head throbs in unison with your heartbeat. Clammy dread coats your body in sweat. Whether you call 911 or someone does it for you, the ER is your next stop.
What do Leo Tolstoy (writer), Beethoven (composer), Paul Gaugin (artist), and Adolf Hitler (politician) have in common? They are all considered to have suffered from the sexually transmitted disease syphilis.
Among the many changes in Android 7.0 Nougat, a less talked-about feature may very well be one of the most interesting. As part of a new system-wide API, apps can now create their own Quick Settings tiles, and it doesn't require any complicated workarounds like it has in versions past.
Sony Corp. is working on new battery technology that the company says would have a 40% longer life than a lithium-ion battery of the same size. Sony is planning to have the higher-capacity batteries on the market around 2020.
Checking the weather ranks among the most mundane but essential tasks you can do on your smartphone. Thankfully, both the iOS App Store and Google Play are loaded with weather apps that add some much needed spice to this daily routine, giving you less of a reason to be caught unaware.
Everyone's forgotten where they parked their car at least once. Either you forget to take note of the section you parked in, or maybe it's more of a Dude, Where's My Car? type of situation. Either way, you're left to circle the same street or parking structure, over and over, with nothing but exhaustion and frustration to show for it.
Living in Southern California means I don't really have a need to check the weather all that often. But every now and then, I'm caught off guard by a particularly chilly or hot day—no one wants to be the only person walking around with a T-shirt and sandals on a rainy, 50-degree day.
Live wallpapers, like the classic Mario-themed one we previously covered, is a great way to spruce up your device and get some simple amusement. Unfortunately, they also drain more battery than conventional wallpapers. Which brings me to ASUS LiveOcean.
With countless images and messages packed into one small device, security is always a high priority amongst iPhone users. For this reason, we've previously shown you how to make your iPhone's passcode match the current time, which made figuring out your passcode a lot more difficult for wandering eyes.
Contrary to popular belief, taking someone's mind off their sadness and telling them to "cheer up" doesn't do much good. Misery loves company, and while it may be a tiresome cliché, there's actually some science behind it.
On a recent trip to Palm Springs, I found myself navigating with Google Maps and virtually exploring my destiniation using its built-in Street View feature. The thing is, using Street View can make keeping track of your exact location difficult as you zoom in, out, and about. It's a little discombobulating.
Volume markings on large pots and mixing bowls make life so much easier. They cut out the step of measuring and save you the trouble of washing measuring cups. However, there aren't many containers out there that actually have volume markers in them.
Adjusting the brightness on your Samsung Galaxy S3 can be a real pain sometimes. Each app you open may need a different amount of light to better optimize its use of the screen, and then you have to worry about it potentially eating up your battery life if it's too bright.
Using a phone that hasn't been updated is like playing NBA 2K10 in 2013. Everything works fine, but you're missing all those new features and current rosters.
If you don't have a car, or just prefer to take public transit to work, you know that an unexpected change in the weather can quickly...er, dampen your day. If you're not expecting it, rain or snow can turn your trip into a long, hellish ordeal—especially if you bike.
With all of the advancements in the smartphone world, we can virtually use them for anything. You can use your smartphone as a mobile hotspot, an Xbox controller, a car locator, and a security camera. Heck, you can even turn it into a Swiss Army knife. And now you can even use it as a wireless mouse for your computer!
In a previous project, I showed how to build an electrical Jacob's ladder using an old microwave oven transformer (MOT). In this project, I modified the secondary coil on the MOT, which converts it from a high voltage/low current device into a low voltage/high current metal melter!
Planning on getting the iPhone 5, but want to keep your SIM card? The new nano-SIMs that manufacturers are adopting will be even smaller than the micro-SIMs that most of us currently use. It's fairly easy to cut a regular SIM down to a micro-SIM, but because the nano-SIM will be thinner as well as smaller than the micro, cutting it down to size will require a little more work.

You've probably seen the classic fruit battery science experiment a thousand times, but I doubt you've ever seen it turned into an art project! Photographer Caleb Charland uses everyday objects like apples, coins and vinegar to create makeshift batteries, then takes these gorgeous long exposure photos. For the apple tree photo, Charland got about 5 volts for every 10 apples, so he had to wire 300 apples to power the lamp for several hours. He used a zinc-coated galvanized nail and copper wire...
Helping to prove that science is way awesome, an 18-year old electrical engineering student has successfully made a light bulb float. His name is Chris Rieger, and he's been working on his "LevLight" project for about six months now, with pretty amazing results. This feat of ingenuity was accomplished by using magnetic levitation, although that over-simplification masks how considerably difficult this undertaking was.
