UA researchers identify the likely culprit of epilepsy

Only 10 years ago, deciphering the genetic information from one individual in a matter of weeks to find a certain disease-causing genetic mutation would have been written off as science fiction. It was the time of the Human Genome Project, and it had taken armies of sequencing robots working around the clock for almost a decade to unravel the complete sequence of the human genetic code - referred to as the genome - by churning out the DNA alphabet letter by letter.

Scientists decode two new blood types

You probably know your blood type: A, B, AB or O. You may even know if you're Rhesus positive or negative. But how about the Langereis blood type? Or the Junior blood type? Positive or negative? Most people have never even heard of these.

MRSA strain in food animals concerns experts

The strain of staph, known as methicillin-resistant Staphylococcus aureus, or MRSA CC398, most often infects farm workers who come in contact with infected pigs, turkeys, or cows. Now the strain of bacteria has been found in about half of meat samples taken throughout the country. The researchers say that the indiscriminate use of antibiotics in livestock used for food is to blame for the infection's drug resistance.

'Good-times' pumps warn cells of approaching starvation

Sugar, cholesterol, phosphates, zinc - a healthy body is amazingly good at keeping such vital nutrients at appropriate levels within its cells. From an engineering point of view, one all-purpose model of pump on the surface of a cell should suffice to keep these levels constant: When the concentration of a nutrient, say, sugar, drops inside the cell, the pump mechanism could simply go into higher gear until the sugar levels are back to normal.

Micronutrients affect methylation, linked to changes in the immune system

The offspring of women who were given micronutrient supplements (minerals needed in small quantities, such as iron, iodine and vitamin A) before they became pregnant had gene modifications at birth as well as when they were tested at 9 months.

High Court extends time allocated for health law arguments

The Supreme Court on Tuesday added an extra 30 minutes to the time provided for oral arguments, bumping up the total to six hours over three days.

Chemists build light-controlled neural inhibitor

The notion of a pain switch is an alluring idea, but is it realistic? Well, chemists at LMU Munich, in collaboration with colleagues in Berkeley and Bordeaux, have now shown in laboratory experiments that it is possible to inhibit the activity of pain-sensitive neurons using an agent that acts as a photosensitive switch. For the LMU researchers, the method primarily represents a valuable tool for probing the neurobiology of pain.

Study on role of genetics and environmental influences on criminal and antisocial behavior

An assistant professor at Sam Houston State University, College of Criminal Justice is working to unlock the mysteries surrounding the role that genetics and environmental influences play on criminal and antisocial behavior.

Over-reactive parents more likely to have toddlers with negative emotionality, problem behaviors

Researchers have found that parents of young children who anger easily and over-react are more likely to have toddlers who act out and become upset easily.

Researchers discover mechanism of thermostat protein

Johns Hopkins and National Taiwan University researchers have discovered more details about how an energy sensing "thermostat" protein determines whether cells will store or use their energy reserves.

Study: MRSA jumps from food animals to humans

A strain of the potentially deadly antibiotic-resistant bacterium known as MRSA has jumped from food animals to humans, according to a new study involving two Northern Arizona University researchers.

Insulin production may persist for decades after onset of type 1 diabetes

Massachusetts General Hospital (MGH) research has found that insulin production may persist for decades after the onset of type 1 diabetes. Beta cell functioning also appears to be preserved in some patients years after apparent loss of pancreatic function. The study results appear in the March issue of Diabetes Care.

Researchers study specially bred mice to understand annual flu epidemics

As part of a national collaboration, Oregon Health & Science University researchers are studying specially bred mice that are more like humans than ever before when it comes to genetic variation. Through these mice, the researchers hope to better understand and treat an infectious disease that plagues us year in and year out: the flu.

Promising antibiotic alternative to fight bacteria that causes strep throat

Researchers have discovered a promising alternative to common antibiotics used to fight the bacteria that causes strep throat. In an article published in the Proceedings of the National Academy of Sciences, the scientists discussed how their discovery could fight the infection with a reduced risk of antibiotic resistance.
