When we get cold sores, the reason is likely related to stress. For the first time, researchers discovered a cellular mechanism that allows the herpes simplex virus to reactivate. They also found how brain cells are duped into allowing this to happen so that the virus can cause disease.

Too many tests at the doctor's office could cost you more than just dollars. In addition to the huge hit to your wallet, there's also the potential harm of false positives, and just because a test has traditionally been done for a condition doesn't mean it's the best way to treat it. One expert is…

The anti-hormone therapy tamoxifen can reduce breast cancer recurrence by about half in women with hormone-sensitive breast cancer. But it works better in some women than others. Researchers are not sure why. New studies add to questions about predicting whether tamoxifen will be effective in an…

Nano implies small -- and that's great for use in medical devices, beauty products and smartphones -- but it's also a problem. All these tiny particles get into our water and are difficult to remove. Now, researchers have a novel and very simple way to take the nanomaterials out.

PET/CT and whole-body MRI detect extraskeletal disease that may change the management of high-risk breast and prostate cancer patients, according to a recent study. In addition, the combined administration of F-18 sodium fluoride (NaF) and F-18 fluorodeoxyglucose (FDG) in a single PET/CT scan…

Children born with cleft lip or palate and spina bifida are at an increased risk for abuse before the age of two, according to researchers. The researchers found that compared to children without birth defects the risk of maltreatment in children with cleft lip and/or palate was increased by 40…

Many of the body's processes follow a natural daily rhythm or so-called circadian clock, so there are certain times of the day when a person is most alert, when the heart is most efficient, and when the body prefers sleep. Even bacteria have a circadian clock, and in a new study, researchers…

Pretty much everything happening in the brain would fail without astrocytes. These star-shaped glia cells are known to have a critical role in synapse creation, nervous tissue repair, and the formation of the blood-brain barrier. But while we have decades of data in mice about these nervous system…

Infinitesimal fluctuations occurring on the milli- and even nano-second time scales within the three-dimensional structure of enzymes may be one of the keys to explaining protein function. Researchers have demonstrated that even when certain amino acids are far from the active site of an enzyme, a…

A map has been created of the DNA loops that comprise the three dimensional (3D) structure of the human genome and contribute to gene regulation in human embryonic stem cells. The location of genes and regulatory elements within this chromosomal framework will help scientists better navigate their…

The birth rate is declining in all industrialized countries, and socioeconomic factors and women's age are not solely to blame. Male reproductive health and environmental factors are also significant, as concluded in a new scientific review article.

Scientists looking at the antiviral mechanisms of two previously identified human monoclonal antibodies have found they potently inhibit chikungunya virus (CHIKV) at multiple stages of infection. These antibodies prevent CHIKV from both entering and exiting cells, an important finding that could…

Although it is known that psychiatric disorders have a strong genetic component, untangling the web of genes contributing to each disease is a daunting task. Scientists have found hundreds of genes that are mutated in patients with disorders such as autism, but each patient usually has only a…

People tend to seek political information that confirms their existing opinion or belief while avoiding contrary information. This is selective exposure, and Internet technologies are likely exacerbating this behavior, according to a new study.

A drug used to treat cancer can neutralize the toxic RNA that causes the prolonged muscle contractions and other symptoms of myotonic dystrophy type 1, the most common form of adult-onset muscular dystrophy, a group of researchers has shown for the first time in cells and in a mouse model.

Patients with in-hospital cardiac arrest have low survival rates -- but why do some hospitals achieve higher survival than others? Higher nurse staffing levels and better working conditions may be part of the answer, reports a new study.

Researchers have been working for years to develop an artificial pancreas in the lab to help the millions of people with type 1 diabetes. But what if the answer is to 'recycle' the more than 300 human pancreata from organ donors that aren't currently being used?

Ethiopia is a hotspot for tuberculosis (TB) infection, ranking third among African countries and eighth in the world for TB burden according to the World Health Organization. But, say researchers who have analyzed the genomes of 66 TB strains, that's most likely not because TB was absent in the…

Mastectomy and reconstruction have the highest rate of complications and complication-related costs, regardless of age, suggests a review of guideline-concordant treatment modalities for women with early stage breast cancer. It was also the most expensive treatment option in a younger patient…
