New memory drug works best in combination with older remedy

An experimental drug combined with an already-popular memory-enhancing compound may further delay memory loss in patients with Alzheimer's disease and other dementias, Johns Hopkins University scientists, in collaboration with researchers from University of North Carolina, have found. more  

People, like other animals, freeze and their heart rate slows upon seeing threatening cues

Standing still when a threat is detected is a defensive, protective reaction. This ancestral and automatic behavior allows the prey to stay unnoticed by a potential predator. more

Deadly infectious entity of prions discovered

The mysterious, highly infectious prions, which cause the severe destruction of the brain that characterizes "mad cow disease" and several human brain degenerative disorders, can be rendered harmless in the laboratory by a slight alternation of the three-dimensional conformation or shape of the prion protein's structure. more  

Risk of heart attack may increase with certain anti-inflammatory drugs

Ibuprofen and other commonly used painkillers for treating inflammation may increase the risk of heart attack, says a study in this week's BMJ. more

Junk DNA shapes social behavior (in rodents) 

Why are some people shy while others are outgoing? A study in the current issue of Science demonstrates for the first time that social behavior may be shaped by differences in the length of seemingly non-functional DNA, sometimes referred to as junk DNA. The finding by researchers at the Yerkes National Primate Research Center of Emory University and the Atlanta-based Center for Behavioral Neuroscience (CBN) has implications for understanding human social behavior and disorders, such as autism. more

Prevention and control of meningococcal disease: Recommendations of the Advisory Committee on Immunization Practices (ACIP) 

CDC’s Advisory Committee on Immunization Practices (ACIP) recommends routine vaccination of persons aged 11–12 years with the new tetravalent meningococcal polysaccharide-protein conjugate vaccine (MCV4) at the preadolescent health-care visit (age 11–12 years). This report discusses the new vaccine recommendation, updates previous reports from ACIP concerning prevention and control of meningococcal disease, and provides updated recommendations regarding use of the tetravalent meningococcal polysaccharide vaccine (MPSV4) and on antimicrobial chemoprophylaxis. more

Benefits of seizure control balanced by unwanted side effects of medication

Giving individuals with single or infrequent seizures immediate treatment does not reduce their risk of seizure recurrence in the long-term, suggests a randomised trial published in this week’s issue of The Lancet. The authors also found that delaying medication did not increase the risk of chronic epilepsy in this group of people. more
