Welcome back, my novice hackers! This next subject might seem a bit obscure, but I promise you, this lesson will benefit you significantly either as a hacker or system admin. This tutorial will cover what is usually referred to as a regular expression, or regex for short.
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.
Imagine this: you have your finger poised to take the perfect picture — a once in a lifetime opportunity, like a solar eclipse — and you are suddenly caught off guard by a buzz, then "ding!" You look down at your phone to find your perfect pic ruined by distortion from the vibration, all because of an ill-timed notification. It's enough to make you crazy, especially when you find out it could have been prevented.
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 search is on to find antibiotics that will work against superbugs — bacteria that are rapidly becoming resistant to many drugs in our antibiotic arsenal.
Legionnaires' disease is named after 1976 outbreak in Philadelphia that sickened 221 people and killed 34. More often striking adults over the age of 50, the Centers for Disease Control and Prevention (CDC) recently reported two cases where newborns contracted the often fatal disease — at their moment of birth.
The possibility of severe tickborne illness is increasing as an aggressive tick from the American southeast moves up the Atlantic Coast.
With summer just ahead, you, or your children, may be looking forward to some pool time or the water park. When planning water-based fun this year, keep a heads-up for microbes.
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.
The bacteria Klebsiella pneumoniae is a bad actor known for being antibiotic-resistant and causing a variety of serious infections in hospitals, including pneumonia, surgical site wounds, and meningitis. K. pneumoniae is something you do not want to encounter if you have a compromised immune system.
In the worst measles outbreak in the state since 1990, the Minneapolis Department of Heath races to contain the spread of an infection believed to have originated from an infected traveler. Mistaken attitudes and unvaccinated travelers are creating a world of hurt and disease for Americans. A recent study found that more than half of eligible travelers from the US are electing to skip their pre-trip measles vaccine.
Fighting fire with fire, scientists are harnessing the adaptability of helpful microbes to challenge the adaptability of deadly microbes. What are we talking about? Hunting with phages — viruses that attack and kill bacteria.
When just floating peacefully in the water with their brood mates, the Culex mosquito larvae in the image above does not look very frightening. But in their adult form, they are the prime vector for spreading West Nile virus — a sometimes mild, sometimes fatal disease.
Have you ever had the stomach flu, aka the 24-hour flu? Well, chances are high that you never had influenza, but an intestinal infection called gastroenteritis.
Arsenic occurs naturally in the environment, but it is also one of the most commonly found heavy metals in wastewater, deposited there by inappropriate disposal and arsenical pesticides, for example.
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.
A robust appetite for imported foods is leading to increased disease outbreak in the US. Despite the locovore and slow food movements, America's demand for foreign foods is picking up. According to a study published in the journal of Emerging Infectious Diseases, demand for imported fresh fruits, vegetables, and seafoods has jumped in recent years.
Even if your cat drives you a little nuts, don't worry, because a new study says that cats pose no risk to your mental health.
Have the sniffles? Yes. Does your head hurt? Yes. Coughing? Yes. Could you have influenza? Yes. How do you know the difference? With these symptoms, you could also have a cold.
Lighthouses and signal fires may have been the first social media. Without the ability to share language, a distant light meant "humans here." A new study from the University of California, San Diego, finds that bacteria can also send out a universal sign to attract the attention of their own, and other bacterial species.
After California college student Luis Ortiz blacked out and was taken to the hospital in 2015, doctors were startled to discover the reason his brain was swelling—a one-centimeter long, wriggling tapeworm living within a ventricle in the middle of his brain.
New weapons are needed to combat antibiotic-resistant bacteria. Instead of drugs, scientists have discovered in an animal study that they may be able to harness vampire bacteria to vanquish pneumonia.
I'll admit it: I ignore expiration dates. No matter if it's a sell-by date, "best if used before" date, or even a use-by date, I don't care. I just check for signs of food decay and keep on eating.
So, you want to become anonymous? well let me give you everything I know (or at least most of it) to you.
A while back, I wrote review of my favorite hacking movies of all time. Two of my key criteria were; (1) how realistic was the hacking, and (2) are the hackers portrayed as the "good guys." This past winter, a new hacker movie was released, appropriately named Blackhat starring Chris Hemsworth (from Thor fame) as a blackhat hacker who is released from prison to stop a notorious and destructive hacker that only he can stop. Although the movie did very poorly at the box office, I thought it was...
Welcome back, my aspiring hackers! As I mentioned in earlier posts, the best hackers (or at least those not behind bars) have a keen understanding of digital forensics. If I am tasked to intrude upon an enemy's file server to retrieve war plans, such as in this tutorial, it is essential to my country's (and my own) well-being that it not be traced back to me. Understanding digital forensics helps us to leave without a trace and never have a trail back to us or our employer.
Just what are probiotics and why are they so good for you? Probiotics are "viable microorganisms" that can confer lots and lots of health benefits if they reach your intestine while they're alive. You may have heard them described as "friendly bacteria."
I'm sure that there are plenty of people out there who have no idea what a plague doctor is/was, so I'll start with an explanation.
There are times when leadership is tested. This is one of those times. As government and business leaders around the world are grappling with the unfolding coronavirus pandemic, the real-time responses to the crisis from many leaders have been great and, at times, less-than-optimal.
In the technology space, there are certain brands you grow to depend on. Whether it's due to a long, multi-decade track record of success, or new innovations that blow you away, some tech names accrue a rare kind of brand equity with users that's difficult to earn.
On the airplane, in the middle of cold and flu season, your seatmate is spewing, despite the clutch of tissues in their lap. Your proximity to an infectious person probably leaves you daydreaming (or is it a nightmare?) of pandemics and estimating how likely it is that this seatmate's viral or bacterial effusions will circulate throughout the plane and infect everyone on board.
Blowing dust and fungal spores are creating a public health problem that could be just a slice of what's to come with climate change.
Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...
Regarding foodborne pathogens, eating fish is not as hazardous as it was a few years ago — but if fins are on the menu, it's good to have a heads-up about what's good and what's bad these days.
Just like your gastrointestinal tract, and the soil we walk on — a dust storm has a collection of bacteria, fungi, and viruses all its own called a "dust microbiome."
A sometimes serious disease spread by fleas is making inroads in Texas, quietly doubling case numbers since 2008, and beginning to encroach on larger metropolitan areas.
You can get eggs and high-quality compost from backyard chickens—but you can also get Salmonella.
It won't come as a surprise to hear that your cell phone, tablet, and laptop are loaded with bacteria and other organic material. While most of these bacteria are harmless, there are good reasons to reduce the capability of your mobile devices to infect you—or other people.
What's in a sneeze? Quite a lot—dirt, mucus, and infectious germs—it seems. And sneezing the right way can reduce the germs you share with neighbors.
The presence of certain bacteria can indicate whether the vaginal tract is healthy or not. It could also impact the likelihood of acquiring certain sexually transmitted diseases, like HIV, a new study suggests.
