When subjects are asked to watch a movie and not display emotions (say, a comedy without laughing, or a tearjerker without crying), they evidently use up glucose in particular areas of their brain in a way that subjects who are free to react however they want do not.
The war on dehydration is a commercially burgeoning marketplace. An increasingly sophisticated consumer population hoping to conquer everything from 26-mile marathons to vodka shots is deconstructing every functional remedy in the fight to quell the effects of severe dehydration.
When Apple removed the Home button from iPhone, it introduced a new way to install apps that caused confusion over what to "double click." Like most iOS changes, it didn't take long to get used to double-clicking the Side button. But for some, performing a double-click on the Side button isn't that easy.
Despite mounting scientific evidence that viruses can cause changes in learning and memory, the reasons have remained elusive.
Having control of your basic motor functions is something most people take for granted, but for individuals with Parkinson's disease, that is not the case.
The Galaxy S5 may be the new kid on the block, with fancy features such as a fingerprint scanner and dust/water protection, but the Galaxy S4 is no slouch by any means. While the S5 may be newer, the S4 remains beast of a device, and few simple mods can make it feel new again.
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.
A new case of the still-mysterious Bourbon virus was confirmed in Missouri, likely originating within the state, local authorities said in a June 30 press release.
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.
Yogurt is more than an excellent source of protein, calcium, and gut-healthy probiotic bacteria. A protein isolated from probiotic lactobacillus bacteria in yogurt is capable of inhibiting drug-resistant bacteria.
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.
Antibiotic-resistant infections that usually occur only in hospital settings are spreading in communities, increasing hospital stays—and danger—for young children.
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.
Most of us equate feeling cold with catching a virus—but we've also heard plenty of debunkers proselytizing that being cold isn't what gives you the flu.
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.
Once we recover from the respiratory infection pneumonia, our lungs are better equipped to deal with the next infection — thanks to some special cells that take up residence there.
More bad news for patients who have undergone heart surgery in the past five years. A new study suggests about one-third of heater-cooler units used in cardiac procedures remain contaminated with a slow-growing, potentially fatal bacteria.
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.
Despite the threat of superbugs, physicians continue to prescribe antibiotics when they might not be needed, and patients are suffering.
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.
Several recent research studies have pointed to the importance of the microbes that live in our gut to many aspects of our health. A recent finding shows how bacteria that penetrate the mucus lining of the colon could play a significant role in diabetes.
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.
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.
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.
Being infected with HIV means a lifetime of antiviral therapy. We can control the infection with those drugs, but we haven't been able to cure people by ridding the body completely of the virus. But thanks to a new study published in Molecular Therapy by scientists at the Lewis Katz School of Medicine (LKSOM) at Temple University and the University of Pittsburgh, all that may change.
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.
In the ongoing search to find better ways to use antibiotics, an extract made from maple syrup has some surprisingly important medical benefits.
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.
By looking for the mechanism that allows influenza A to invade lung cells, scientists also discovered a treatment that might block the virus from taking hold there.
New research suggests the bacteria that causes listeriosis may be a bigger threat in early pregnancy than previously thought. Usually considered a danger to late pregnancy, scientists suggest early undiagnosed miscarriages could be caused, in some cases, by infection with Listeria.
Avian flu is making the news again with new human cases in China reported in January. What does "avian flu" mean to you—and how dangerous is it?
As fun as it is to see Fido's face light up when you feed him table scraps, American dogs are getting fat. The good news is that research is homing in on nutritional strategies to boost canine capabilities to maintain a healthy weight.
A recent pathogen outbreak in Illinois is just one of many outbreaks of an underappreciated, but serious, viral infection passed from rodents to humans. These hantaviruses have been cropping up more frequently in the last decade or so, giving us more reason to clean out our dusty attics, basements, and garages.
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.
Eating healthy poses a challenge nowadays with so many options that taste great but aren't really good for you. Nutritionists have made it their life's work to understand what actually does a body good. Here's how you can follow their example.
In the US, ticks can spread several pathogens in one bite. A new test offers physicians the ability to identify what infections ticks are carrying and can detect if one of the pathogens could be the spreading Powassan virus.
HIV-infected people who are treated long-term with antiviral drugs may have no detectable virus in their body, but scientists know there are pools of the virus hiding there, awaiting the chance to emerge and wreak havoc again. Since scientists discovered these latent pools, they have been trying to figure out if the remaining HIV is the cause of or caused by increased activation of the immune system.
You can get eggs and high-quality compost from backyard chickens—but you can also get Salmonella.
Prion diseases are a group of infectious brain diseases that causes extensive tissue damage, resulting in sponge-like spaces in brain tissue. Prions include Creutzfeldt-Jakob disease in humans, bovine spongiform encephalopathy (often called mad cow disease), and chronic wasting disease in hoofed ruminant mammals.
Cats give us so much—companionship, loyalty, love... and now the bird flu. Several weeks ago, a veterinarian from the Animal Care Centers of New York City's Manhattan shelter caught H7N2 from a sick cat. According to a press release from the NYC Health Department on December 22, "The illness was mild, short-lived, and has resolved." This isn't the first time cats have passed infections on to humans, but it is the first time they passed on the bird flu—avian flu H7N2, to be exact.
