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.
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.
Scientists know that bacteria create their own energy, get nutrients to run their cellular processes, and multiply. But, bacteria haven't been shown to respond to external mechanical stimulation or signals in a way that's similar to how our bodies respond to touch, until now.
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.
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.
Malaria is a massive worldwide health problem. The Centers for Disease Control and Prevention estimate that 212 million cases of malaria occurred worldwide in 2015 and 429,000 of the infected people died.
About a third of the methane released into the environment comes from the production and transport of natural gas. The gas leaks as it moves along the transport chain from gas wellheads to market.
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.
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.
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.
Even though HIV rates declined 18% between 2008 and 2014, 1.1 million people in the US are living with the infection. Part of that is because HIV is treatable, but not curable.
It is not just a bad summer for ticks — it has been a bad decade for the spread of tick-borne infections. New surveillance from the CDC reports rapid expansion and increase in cases of babesiosis, a sometimes life-threatening disease, in Wisconsin.
Tony Parisi, the global head of VR/AR at Unity Technologies, has been passionately working with virtual and immersive spaces for a long time. And while the internet world we live in now is very different than when Parisi was co-authoring VRML (Virtual Reality Modeling Language) — an early attempt at creating 3D environments that would work in a web browser — some of the questions that were assumed answered are being asked again.
Coronaviruses are common viruses, and most of us catch one at some point — they cause about 30% of all common colds. A new accidental discovery could help fight these viruses, even the deadlier, emerging ones.
Alzheimer's disease — an irreversible, progressive brain disorder — is the sixth leading cause of death in the US and more than afflicts 5 million Americans. As if those numbers aren't scary enough, the Centers for Disease Control and Prevention expect that number to nearly triple by 2050.
The possibility of severe tickborne illness is increasing as an aggressive tick from the American southeast moves up the Atlantic Coast.
Activating the body's own immune system to fight cancer is the goal of immunotherapy. It's less toxic than chemotherapy and works with our body's natural defenses. The trouble is, it doesn't work for most patients — only about 40% of cancer patients get a good response from immunotherapy. But coupling it with another type of cancer therapy just might deliver the punch that's needed to knock out cancer.
Drug-resistant bacteria have made curing some infections challenging, if not nearly impossible. By 2050, it's estimated that 10 million people will be dying annually from infections with antibiotic-resistant organisms.
As headlines focus on melting glaciers and rising water levels caused by global warming, climate change is quietly taking its toll on the nearly invisible occupants of this planet, the microbes.
Lyme is a growing threat as we move into warmer weather in the US. Researchers have said this year could be one of the worst for this tick-borne disease, as a skyrocketing mouse population and warmer temperatures increase the risk.
Water makes up about 60% of your body weight. Whether you like it plain, flavored, bubbly, or in beverages or food, we all need water daily to avoid dehydration and stay healthy. For communities in need of clean drinking water, new research using bacteria may offer a simplified, lower-cost method for boosting potable water supplies.
The evolution of our infection-fighting systems may have something to teach modern scientists. That's what a group from the University of Granada in Spain found when they studied a protein that's been around for over four billion years. Their work, by senior author José Sánchez-Ruiz and colleagues in the Department of Physical Chemistry, was published in the journal Cell Reports.
In order for software developers to do their jobs as new hardware reaches the market, they will need the right tools to get their projects off the ground and into augmented and mixed reality devices. There have been completely new approaches to development when it comes to AR and MR, and these are some of the faces behind them.
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.
Facebook really wants us to use Messenger. For the most part, they've succeeded; theirs is one of the most popular messaging apps right now. And with yesterday's announcement of new features, Facebook is only going to make their flagship chat application better.
Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.
Antibiotics used to prevent diseases in livestock are creating a world of hurt for humans and the soil we depend on for food. Bacterial resistance to antibiotics is a global health issue. The overuse, underuse, and poor use of these life-saving drugs is rapidly removing them as a treatment option for serious infections in humans—plus bacteria are naturally adaptive.
Viral infections have been the focus of attention in the development of autoimmune diseases—diseases where the body's immune system reacts to the body's own cells—because they trigger the immune system into action.
To keep fungal pathogens at bay in their crowded homes, wood ants mix potions to create powerful protection for their nest and their young.
Most females have had at least one urinary tract infection in their lifetimes. Recurrent UTIs are particularly problematic in young, sexually active women, where about 80% of the infections are caused by the bacteria Escherichia coli, better known as E. coli.
The search for a cancer treatment that selectively finds and kills only the cancerous cells has just made a giant leap forward.
The Great Barrier Reef in Australia is the largest living system on the planet. Yet more than 90% of the reef is bleaching because of the loss of a tiny algae that lives within the coral.
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.
Hospitals are places we go to get well, and we don't expect to get sick or sicker there. But a study from researchers at the Cleveland Clinic, Case Western Reserve University School of Medicine, and Cleveland VA Medical Center in Ohio found that hospital floors in patient rooms were frequently contaminated with healthcare-associated pathogens—often dangerous multi-drug resistant bacteria.
A new study confirms that antibiotics can prevent surgical intervention if your child's appendix becomes inflamed, potentially saving his or her life.
As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.
Ecosystem changes caused by agricultural choices in Brazil are creating a dangerous microbe mix in exploding populations of vampire bats and feral pigs.
Seagrass may help your favorite beach stay a little less toxic. A new study, led by Joleah Lamb, a postdoctoral researcher in the Harvell Lab at Cornell University, found that coastal seagrasses reduce levels of pathogens dangerous to humans and marine organisms in near-shore waters.
Responding to the emergence of Zika in the US, researchers investigated what type of repellent works best to reduce your odds of a mosquito bite from Aedes aegypti, the mosquito species that spreads the Zika virus.
