When it comes to global warming, most of us think of carbon dioxide emissions. While carbon dioxide is the most important greenhouse gas, carbon dioxide emissions have stayed constant for the last three years. On the other hand, methane, the second most important gas, has been steadily rising since 2007.
Add antibiotics to the possible list of culprits responsible for honeybee decline around the world. While it may come as a surprise, antibiotics are commonly mixed into feed used by commercial beekeepers to maintain their hives. In a recent study published in PLOS Biology, researchers from the University of Texas at Austin found antibiotics used to treat honeybees may be a contributing factor in individual bee death and colony collapse.
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.
With augmented reality comes an infinite realm of possibilities for storytelling. We have seen it through wineries telling their history with interactive AR experiences and through authors that use augmented reality to bring portions of their books to life. However, filmmaker Peter Jackson might take the cake on creating an incredible new way of storytelling.
Take a close look at the image above. These bugs spread a deadly parasite that infects thousands of people each year. They also live in the US, and it's important to know where they are and whether you need to worry that they're carrying a dangerous infection.
Greetings, my friend. Welcome to Null Byte. I am Dr. Crashdump. Linux will be talked about a lot in Null Byte. It's used in most tutorials on this site, actually. You should learn how to use Linux as soon as possible, but where do you start? No worries. Let's figure that out.
Legal Services A group of lawyers refused to provide legal services to needy AARP members for $30 per hour, but when asked to do it for free, they readily agreed.
Despite mounting scientific evidence that viruses can cause changes in learning and memory, the reasons have remained elusive.
My message to Russian hackers is this: LEAVE BRITNEY ALONE! Russian hacking collective Turla has been targeting governments and military operations in the United States, Europe, Asia, and the Middle East for the past decade. Now, it appears that the group is targeting everyday citizens — specifically Britney Spears fans.
I found this article a while back and I found it underneath a bunch of junk. Anyway, it's a article on 9 notorious hacker including Walter O'Brien (You know the T.V. show Scorpion? Well that's him). Not to mention the weird names:
In case you thought the long and unfortunate story of ODG was over, hold on, there's one last chapter to tell.
A new study shows the Zika virus is present in saliva — but it may not be enough to make you sick. The Centers for Disease Control and Prevention notes there is "no evidence that Zika can be transmitted through saliva during deep kissing." Given the results of research published in the journal, Nature Communications," the agency may need to revise its guidance.
The number of households in the US that go hungry because they lack money for food hit a high of almost 15% in 2011. While that number continues to decline, nearly 13% of American households still go hungry.
Growing evidence suggests that neurodegenerative diseases like Parkinson's may develop in part due to environmental factors, including infections that can cause inflammation in the nervous system. New research from investigators from Jude Children's Research Hospital and Thomas Jefferson University has strengthened that connection.
As our cells age, they eventually mature and die. As they die, they alert nearby cells to grow and multiply to replace them. Using a special imaging process that combines video and microscopy, scientists have observed the cellular communication between dying and neighboring cells for the first time, and think they may be able to use their new-found information against cancer cells, whose damaged genomes let them escape the normal dying process.
A promising new antibiotic has been discovered in, of all things, another bacteria. Burkholderia bacteria live in diverse habitats, including soil, plants, and humans where they thrive by knocking out other microbes that compete with them for resources or threaten their existence. Scientists have discovered they accomplish this by producing a very effective antibiotic.
New research reveals how E. coli bacteria construct elaborate and effective tunnels to pump unwanted molecules like antibiotics and other toxins out of cells. The discovery could help us better understand how antibiotic resistance occurs and give us a leg-up to beat them at their own game.
What would it be like to have clothing that killed microbes? Or paper that repelled pathogens? A research team from Rutgers University has developed a prototype out of metalized paper to zap the bad guys without being super expensive. Sound good? Read on.
If the all the fingerlike projections in our gut were flattened out, its surface area would be 100 times bigger than our skin's. It's so large that the actions of just a small part of it can impact our health. A new research study has found that enterochromaffin cells in the intestinal lining alert the nervous system to signs of trouble in the gut — trouble that ranges from bacterial products to inflammatory food molecules.
Electrical impulses course through our heart and keep it beating. That's why a jolt from an automated external defibrillator can boost it back into action if the beating stops. But new research says there may be more to keeping a heart beating than just electrical impulses.
Usually, we think of vaccines as preventative, a shot we get to prevent the flu or some childhood disease like measles or mumps. But there are vaccines for other purposes, such as the ones studied by researchers from the Netherlands.
Having a Clostridium difficile infection means stomach pains, diarrhea, fever, and loss of appetite, and if the symptoms weren't bad enough, the disease often reoccurs. Now, new research has found an increased risk of recurrence in people who take medication to treat their stomach acid, gastroesophageal reflux disease, peptic ulcer disease, or stomach discomfort.
Antibiotic-resistant infections that usually occur only in hospital settings are spreading in communities, increasing hospital stays—and danger—for young children.
The mention of Zika can strike fear in the hearts of pregnant women. With infections increasing around the world, including in the US, researchers are fighting the clock to figure out how the virus can have such horrific effects in some people.
There is plenty of evidence to suggest that learning to program is becoming a highly lucrative and useful skill. Monster.com called coding "the skill you need today" if you want a job in some of the highest-paying fields out there. If the last year has proven anything, working online requires a strong digital infrastructure that someone has to help build. That someone can, and should, be you.
A virus easily spread among trout and salmon could make it harder to keep your favorite fish on the menu.
A vaccine against HIV might prevent the disease that we can't seem to cure. Some HIV patients make antibodies that can take down the virus, much the way a vaccine might. But, scientists haven't been able to provoke that type of response in other people. However, in a process that might work in humans, a group of researchers has successfully generated antibodies in cows that neutralize multiple strains of HIV.
Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.
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.
A recent study offers information that might help combat a deadly virus that affects an estimated 300,000 people each year in West Africa.
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.
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.
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.
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.
Cancer cells do a pretty good job of flying under the radar of our immune system. They don't raise the alarm bells signaling they are a foreign invader the way viruses do. That might be something scientists can change, though.
Not all bacteria in the eyes cause infection. A group of researchers from the National Eye Institue has shown that not only is there a population of bacteria on the eyes that reside there but they perform an important function. They help activate the immune system to get rid of bad, potentially infection-causing — pathogenic — bacteria there.
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.
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.
