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.
With a death rate of one in five, sepsis is a fast-moving medical nightmare. New testing methods might improve your odds of survival if this infection ever hits you.
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 herpes simplex virus (HSV) can cause devastating complications for infected newborns whose mothers have genital herpes. Understanding risk and research can help you, and your baby, when the time comes.
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.
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.
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.
Even before we are born, our immune system is hard at work. New research shows how the developing fetal immune system takes advantage of the time and opportunity of gestation — in the presence of mom's cells and tissues — to develop a sense of self.
Intense exercise can cause problems with our digestive tract. It even has a name — "Exercise-induced Gastrointestinal Syndrome." Simply put, strenuous exercise can damage the gut and let the bacteria that reside there potentially pass into the bloodstream.
Most of us have already had an encounter with the Epstein-Barr virus, or EBV, for short. As part of the herpes family, it's one of the most common disease-causing viruses in humans. We get the disease with (or without) some nasty symptoms, then we recover. However, EBV stays in our body after the illness has ended, and it's one of the few viruses known to cause cancer.
Long admired for their active and cooperative community behavior, some types of ants also wear a gardening hat. Nurturing underground fungus gardens, these ants have a win-win relationship that provides food for both ants and fungi. If we humans understand it better, it may just help us out, too.
Breastfeeding is the ultimate in farm-to-table dining. It is sustenance prepared just for the baby and delivered with a very personal touch. Along with bonding, breastfeeding provides powerful protection to infants and young children in the form of beneficial bacteria, hormones, vitamins, protein, sugar, and antibodies manufactured on site to support infant health.
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.
Termite poop and biofuels — what's the connection? New research into termites' intestinal comings and goings describes a process that may speed the development and lower the cost of fuels made from plant matter.
It's about time people acknowledged that judging drug users would do nothing productive to help them. In the US this week, two new programs are launching that should help addicts be a little safer: Walgreens Healthcare Clinic will begin offering to test for HIV and hepatitis C next week, and Las Vegas is set to introduce clean syringe vending machines to stop infections from dirty needles.
In the ongoing search to find better ways to use antibiotics, an extract made from maple syrup has some surprisingly important medical benefits.
Growing populations and higher temperatures put pressure on world food supplies. Naturally occurring soil bacteria may save crops in drought-stressed areas, put more land into crop production, and produce more food.
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.
Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.
The culprit probably wasn't what doctors were expecting when a 57-year-old man in Hong Kong came to the hospital. The patient was admitted to the intensive care unit in critical condition. A clue to the cause of the infection would lie in the man's profession—he was a butcher.
A new study has found that up to half of people who think they have a penicillin "allergy" can still receive the drug, and other antibiotics with similar structures, without any negative reactions to the meds. Why? Because they're not really allergic, doctors say.
For regions that experienced a boom in mouse populations last year, scientists say 2017 could see a surge in cases of Lyme disease.
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 just out reveals that HIV takes hold in the human body with the help of cells that usually work to heal, not kill.
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.
The pathogen referred to as a "nightmare bacteria" is quietly adapting and spreading faster than anticipated.
Transmitted by a sandfly one-third the size of a mosquito, parasitic Leishmania protozoa are responsible for a flesh-destroying disease that kills an estimated 20,000 people per year. Two new studies offer understanding of how the parasite provides immunity through persistence and why some people suffer more virulent forms of the disease.
Despite the availability of a vaccine against it, almost 50% of men aged 18-59 in the US are infected with the human papillomavirus (HPV). Why?
Responding to the rapid emergence of dangerous pathogens around the world, a new initiative to prevent or contain pandemics was announced in Davos, Switzerland, yesterday. If you ever worried that a highly contagious pathogen could take down your community, or the country, this news is for you.
You might feel the bite, you might not, but an infected mosquito has injected you with a parasite named Plasmodium falciparum, a single-cell protozoa that quickly takes up residence in your body.
Transmitted by ticks, Lyme disease is a serious infection that is probably headed your way. A recent study confirms the pathogen that causes Lyme disease is now established in nine national parks in the East, including Acadia and Shenandoah National Parks.
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.
I'm sure I'm not the only one on here that has googled "Why am I always tired?"... and I'm definitely not alone when I say that all of the advice I've found so far is useless:
When Google released the first Developer Preview build of Android 7.0 Nougat, users were happy to see that a new "Night Mode" was included among the changes. The feature would cancel out any blue light emitted from your screen to help you get to sleep a bit earlier, quite similar to f.lux for desktop computers, or Apple's Night Shift for iPhones. It could be set to turn on automatically based on time of day, or you could manually enable Night Mode with a Quick Settings toggle.
Most of the time we only use the microwave to reheat or defrost, but you can actually save a lot of time by using it for cooking. These genius recipes make the most of this underused appliance, and also turn out some pretty tasty dishes.
No one ever wants to experience pain, whether it's as small as a stubbed toe or as great as recovering from surgery. Yet so much of our lives causes pain, lasting or brief in its form. With a few mental tricks and unusual home remedies, you can relieve some of the most common aches and ailments that arise painlessly.
There are so many cutesy pink, red, and heart-shaped desserts and drinks put out on Valentine's Day, but none of those really get you into a low-light mood. Instead, turn up the heat with one of these aphrodisiac cocktails for grown-ups.
