Quick Test may Speed Antibiotic Treatment Combat Drug Resistance

Described in Scientific Reports, NIST's prototype sensor provides results in less than an hour, much faster than conventional antimicrobial tests, which typically require days to grow colonies of bacterial cells. Delayed results from conventional tests allow dangerous infections to progress before effective treatments can be found and provides a time window

A New Study Reveals that Our Body Mass Index Interacts with our Appreciation of Food Characteristics

"It can be considered an instance of 'embodiment' in which our brain interacts with our body." This is the comment made by Raffaella Rumiati, neuroscientist at the International School for Advanced Studies -- SISSA in Trieste, on the results of research carried out by her group which reveals that the

Oxytocin Turns up the Volume of Your Social Environment

Sometimes popularly called the "love hormone," oxytocin is a hormone released in the brain that plays a major role in social relationships. The new work by behavioral neuroscientists Natalia Duque-Wilckens and Brian Trainor shows that after negative social interactions, oxytocin promotes avoidance of unfamiliar social situations. Trainor and Duque-Wilckens worked with

PET imaging tracks Zika virus infection, disease progression in mouse model

Small-animal imaging has become an important research tool for preclinical studies of infectious diseases, according to senior author Thomas M. Bocan, Ph.D., of the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID). "Traditional methods of infectious disease research using animal models have provided limited information about disease progression until the

Congenital Hyperinsulinism A Serious Yet Poorly Understood Condition

The disorder can therefore lead to serious brain damage and even death in the worst cases. A team at the University of Geneva (UNIGE), Switzerland, supported by the Swiss National Science Foundation (SNSF) has succeeded in precisely describing the effects of a frequent genetic mutation in cases of congenital hyperinsulinism.

Ricin only Lethal in Combination with Sugar

The plant toxin ricin is one of the most poisonous naturally occurring proteins, making it an extremely dangerous bioweapon. Ricin attacks have made the headlines a number of times over the years, including the spectacular "umbrella murder" in London in the 1970s, or more recently the ricin letters addressed to

Nanocapsules Enable Cell-Inspired Metabolic Reactions

Metabolic processes inside living organisms involve a large variety of bio-molecules. These molecules are produced by specific enzymatic reactions. One example of such a bio-molecule is glucose-6-phosphate, a metabolite that is involved in important metabolic processes. It is central in the degradation of carbohydrates and can also be converted further

Brain’s reward center activity may protect against negative mental health effects

Individuals whose brains are more attuned to rewards may be protected from the negative mental health effects of poor sleep, says a new study by Duke University neuroscientists. The researchers found that college students with poor quality sleep were less likely to have symptoms of depression if they also had higher

Prototype Separates Components of Blood for Diagnostics

The system is optimized to sort out "exosomes," biological nanoparticles released from every type of cell in the body. Thought to play a large role in cell-to-cell communication and disease transmission, they have been objects of scientific curiosity since their discovery three decades ago. The miniscule size of exosomes, however, makes

‘Exciting’ discovery on path to develop new type of vaccine to treat global viruses

In a study published in Science Immunology, researchers have shown that natural killer cells (NK cells), which are a fundamental part of the body's immune system, can recognise many different viruses including global pathogens such as Zika, dengue and Hepatitis C viruses, through a single receptor called KIR2DS2. Lead researcher Salim Khakoo,
