A more than 50-year-old question has now been answered. Chemists and microbiologists are now able to describe in detail the role of calcium in the ability of the plague bacterium Yersinias to cause disease.
Epilepsy and depression are common co-morbidities. Concern for the potential of certain antidepressants to induce seizures has led to under-treating depression and anxiety disorders in epilepsy patients. Research suggests that antidepressants in normal do

Researchers have developed a model that uses neonatal piglets for studying infant brain development and its effect on learning and memory. To determine if the model is nutrient-sensitive, they have looked at how pigs fed iron-deficient diets perform in a
Scientists have found that low-level exposure to organophosphates produces lasting decrements in neurological and cognitive function. Memory and information processing speed are affected to a greater degree than other cognitive functions such as language.
Many epilepsy patients believe that stress is a factor in their seizure control, while many other epilepsy patients do not have this perception. To better understand the potential role of stress among these patients, researchers conducted a functional neu
More than a million people die each year of malaria caused by different strains of the Plasmodiumparasite transmitted by the Anopheles mosquito. The medical world has yet to find an effective vaccine against the deadly parasite, which mainly affects pregn
In the first study to compare mental health-related emergency department (ED) visits between children with and without autism spectrum disorders (ASD), researchers found that ED visits are nine times more likely to be for psychiatric reasons if a child ha
Researchers have discovered four new gene regions that contribute to low birth weight. Three of those regions influence adult metabolism, including outcomes such as adult height, risk of type 2 diabetes and adult blood pressure.
West Nile virus, Lyme disease, dengue fever, and plague are examples of "vector-borne zoonotic diseases," caused by pathogens that naturally infect wildlife and are transmitted to humans by vectors such as mosquitoes or ticks. Land-use change, g
Experts are recommending early post-surgical assessment -- preferably within 24 hours -- for trouble chewing and swallowing food, or speaking normally, among patients who have had benign tumors removed from the base of the brain.

The treatment of inflammatory pain can be improved by endogenous opioid peptides acting directly in injured tissue. Scientists have shown that pain can be successfully treated by targeting immune and nerve cells outside the brain or spinal cord.
A medical sensor that attaches to the skin like a temporary tattoo could make it easier for doctors to detect metabolic problems in patients and for coaches to fine-tune athletes’ training routines. And the entire sensor comes in a thin, flexibl
In a genome sequencing study of 74 neuroblastoma tumors in children, scientists have found that patients with changes in two genes, ARID1A and ARID1B, survive only a quarter as long as patients without the changes. The discovery could eventually lead to e

Researchers have found that deficiencies in the neural processing of simple auditory tones can evolve into a cascade of dysfunctional information processing across wide swaths of the brain in patients with schizophrenia.
A protein known as monocarboxylate transporter 1 (MCT1), which is highly expressed in a subset of metabolically altered cancer cells, is needed for the entry of the investigational cancer drug 3-bromopyruvate (3-BrPA) into malignant cells.

Researchers report that lithium, a drug commonly used for the treatment of mood disorders in humans, restores neurogenesis in the hippocampus, a part of the brain strongly associated with learning and memory.
A tiny, translucent zebrafish that glows green when its liver makes glucose has helped researchers identify a compound that regulates whole-body metabolism and appears to protect obese mice from signs of metabolic disorders.
