It's not the bacteria itself that takes lives and limbs during invasive flesh-eating bacteria infections. It's the toxins secreted by the group A Streptococcus bacteria invading the body that causes the most damage.
Usually, the mucus lining of the female genital tract presents a barrier that helps prevent infections. But, somehow, the bacteria that causes gonorrhea gets around and through that barrier to invade the female genital tract.
Onshore, or on a boat, have you ever wondered what swims below in the dark water? Using standard equipment and a new process, marine scientists can now get a good look at what is swimming by—just by analyzing the water.
Antibiotic-resistant infections that usually occur only in hospital settings are spreading in communities, increasing hospital stays—and danger—for young children.
Some bacteria can already do it—generate electric current, that is—and those microbes are called "electrogenic." Now, thanks to the work of a research group from the University of California, Santa Barbara, we know how to easily turn non-electrogenic bacteria into electricity producers.
We usually associate Salmonella bacteria with a dangerous type of food poisoning, but they actually are pretty good at seeking out tumors. That trait made the bacteria a great candidate to deliver a protein that would help knock tumors out.
Sleep lets our body processes rest and restores us for the next day, so a bad night's sleep can ruin the following twenty-four hours and even make us feel sick. Now, new research published in the journal Sleep cements the idea that loss of sleep actually leaves us vulnerable to sickness.
No one can dispute the evolutionary success of bugs. The oldest insect fossils were found encased in crystallized mineral silica in Scotland in 1926, and they're between 396 and 407 million years old.
We've all been there: facing a lengthy, complex word that ignores the phonics we were taught in elementary school, unsure of not only its pronunciation, but also its meaning. These words, from autochthonous to esquamulose, are both terrifying and impressive. After all, if someone knows how to use them—and even say them—they must be quite smart. Yet before you begin stuffing every email and presentation with verbose prose, you might want to reconsider what others perceive to be intelligent.
Most of you already know that a zero-day exploit is an exploit that has not yet been revealed to the software vendor or the public. As a result, the vulnerability that enables the exploit hasn't been patched. This means that someone with a zero-day exploit can hack into any system that has that particular configuration or software, giving them free reign to steal information, identities, credit card info, and spy on victims.
Are you a follower or a leader? No matter how you respond, we all know that leader is a more desirable position to hold. Great leaders typically share a few qualities—confidence, intelligence, and strength, to name a few—but one of the most intriguing is their appearance. With the right facial structure, and some well-rehearsed expressions, you can trick others into thinking you're leader material.
From parents and other family members to friends and peers, personalities are built by environment. Though people are important in the development of our own individual personality, there are other, different influences, including what you choose to read. The books you take the time to enjoy can make you nicer and more understanding, or leave you overall unchanged.
Decisions are rarely easy to make, and there are countless ways to mull your options over. You can sleep on it, pluck flower petals, make a list of pros and cons, or even follow the advice of a psychic. Yet to make the best decision possible, you might want to consider holding off until a certain time of the day—or even until you feel specific emotions. The state you find yourself in has significant impact on each decision you make.
Can you tell when someone is shooting you a fake smile? Even though fake smiles are easy enough to see through, we all still do it, attempting to show others just how happy we are when we're really feeling less than fantastic. Unfortunately, every smile we fake makes us a tiny bit more miserable.
Naps provide some serious mental and physical benefits, but not if they last too long or occur too late in the day. Ideally, you want to awake from a nap feeling alert and refreshed enough to attack the rest of your tasks with renewed zeal, but not energized to the point where you can't get to sleep at night. Alas, most of us don't know these tricks and end up messing with our sleep cycle (guilty).
Most days, getting through an eight-hour work shift is a struggle. There are a million places you'd rather be, and none of them include your desk. It's difficult to find the motivation to tackle the growing number of emails in your inbox when your mind is back at home, comfortable in front of your gaming system.
I have an embarrassing habit: I type with six fingers. Just as your grandma pecks at the keyboard with her two index fingers, I rely solely on my index, middle, and thumb fingers only. But it's not as slow as you think, and I'm not the only one out there that does it.
We go to such great lengths to secure our smartphones. We put passwords on our lock screens, encrypt our data, and install anti-theft programs, but it's never enough—someone, somewhere, will find a way around any protective measure you use, no matter how sophisticated.
Got some information you want to circulate quickly and extensively? Learn what it takes to get people to pass it along.
Open-source intelligence researchers and hackers alike love social media for reconnaissance. Websites like Twitter offer vast, searchable databases updated in real time by millions of users, but it can be incredibly time-consuming to sift through manually. Thankfully, tools like Twint can crawl through years of Twitter data to dig up any information with a single terminal command.
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.
There's no doubt Kali has established itself as the most popular penetration distribution available. However, just because it's the fan favorite of beginners and security researchers doesn't make it right for everyone. Manjaro Linux is a beginner-friendly Arch-based distribution which can be easily weaponized with the Black Arch expansion, creating a friendlier first-time Arch experience.
As unappealing as it sounds, transplants with fecal material from healthy donors help treat tough Clostridium difficile gastrointestinal infections. Researchers credit the treatment's success to its ability to restore a healthy bacterial balance to the bowels, and new research has shown that the transplanted bacteria doesn't just do its job and leave. The good fecal bacteria and its benefits can persist for years.
Despite legends to the contrary, it appears that the saliva of a Komodo dragon is not teeming with pathogenic bacteria that kills their prey. Its reputation to survive while colonized with lots of horrible disease-causing bacteria, true or untrue, has made it the subject of research in pursuit of natural antimicrobial agents and led scientists to some remarkable findings.
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.
This time last year, Snap CEO Evan Spiegel and his company were faced with an erosion of its user base that cratered its stock price. This year, on the strength of Snapchat's AR camera effects, the company has reversed course. And that's why Spiegel tops the NR30, our annual list of the leaders in the AR industry.
How can a drug used to treat cancer be effective against viruses, too? The answer lies in the drug's shared target — specifically, cellular components that control the activity of genes. A new research study showed that one such type of drug, histone methyltransferase inhibitors used in cancer clinical trials, has activity against herpes simplex virus, too.
Love is the spice of life — it is also the microbes that couples share through sickness and in health, through the bathroom and in a hallway.
More than one in ten people in the US have type 2 diabetes — that's over 29 million people. It's characterized by excessive sugar (glucose) in the blood due to the development of resistance to insulin, the hormone that normally metabolizes glucose.
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.
On July 20, 1969, humans set foot on the moon for the first time. But some say our microbes beat us there. With the Space Age came new questions about microscopic invaders from outer space and concern about where we are leaving our microbial footprints. The questions are even more relevant today.
A week into my internship, I experienced pretty serious back pain and slight difficulty breathing. I scheduled a doctor's appointment to make sure nothing was wrong, and I got a surprising diagnosis: bad posture.
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.
Colorectal cancer — cancer of the colon or rectum — is the third most commonly diagnosed cancer in the US. To reduce the chances of a diagnosis we are all urged to stop smoking, keep our weight down, decrease our intake of alcohol and red meat, keep active, and get screened for colon cancer. But, new research has found something that participates in the development of colorectal cancer that might not be as easy to control: A strep bacteria that promotes tumor growth.
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.
Montezuma's revenge, the runs, the trots, or just diarrhea — everyone gets it sooner or later. What exactly is diarrhea good for, if anything?
The Deepwater Horizon oil spill that began on April 20, 2010, was the largest maritime oil spill in history. Killing 11 people and discharging 4.1 million barrels of oil and natural gas into the Gulf of Mexico, the event was an unparalleled personal, environmental, and business disaster. It was also the first major oil spill to take place in the deep ocean.
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.
Look no further than Flint, Michigan, to discover the serious consequences of contaminated drinking water. Around the world, water polluted by pathogens and toxins sickens people or cuts them off from safe drinking water. Looking for a solution, researchers created tiny, swimming robots that pack a powerful punch against waterborne pathogens.
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.
