Researchers describe how postmortem brain slices can be 'read' to determine how a rat was trained to behave in response to specific sounds, a new article suggests. The work provides one of the first examples of how specific changes in the activity of individual neurons encode particular acts of learning and memory in the brain. It sounds like the stuffRead more

Australian researchers have discovered that a unique form of carbon -- which can be created by drawing on paper -- holds the key to faster DNA sequencing, which would revolutionize medical research and testing worldwide. Dr Jiri Cervenka and PhD candidate Nikolai Dontschuk, from the University of Melbourne, have discovered that graphene, a two- dimensional form of carbon just oneRead more

Iranian researchers presented a novel method to measure and determine the medical formulations and purity of chiral materials in them. The proposed method is cheap, sensitive and simple in comparison with the existing methods, and it does not need any separation process. Many chemical compounds used in the formulation of drugs have one or a few chiral centers. Various enantiomersRead more

Iranian researchers from Bu-Ali Sina University, Hamedan, proposed a new, simple and cost-efficient method to determine toxic fungal species existing in foodstuff. Results of the research enable the execution of quick and exact quality control tests in foodstuff industries and controlling and supervising organizations such as Food and Drug Organization. There exist at the moment more than 300 types ofRead more

Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, a new research showed. The research, published Feb. 25 in Nature, was led by Georgia State University Institute for Biomedical Sciences' researchersRead more

Exposure to air pollution in the womb may be bad for children's brains and may contribute to slower processing speeds and behavioral problems, including attention deficit hyperactivity disorder (ADHD) symptoms, a small imaging study of 40 kids said Wednesday. The study, published in the U.S. journal JAMA Psychiatry, focused on polycyclic aromatic hydrocarbons (PAHs), the toxic air pollutants caused byRead more

Scientists have found a new gene linked to body fat distribution in research that may help explain why you have an apple or pear shape. Researchers from the Duke University reported Monday in the U.S. journal Proceedings of the National Academy of Sciences that a gene called Plexin D1 could control both where fat is stored and how fat cellsRead more

Man's memory is worse than the woman's and the male brain part that controls memories is smaller, a study published in JAMA Neurology medical journal said. "That's right, that's what the data says," said Dr. Clifford Jack of the Mayo Clinic. "We see worse memory and worse brain volumes in men than women from age 40s onward." The researchers saidRead more

For patients with diabetes, insulin is critical to maintaining good health and normal blood-sugar levels; however, it's not an ideal solution because it can be difficult for patients to determine exactly how much insulin they need to prevent their blood sugar from swinging too high or too low. MIT engineers hope to improve treatment for diabetes patients with a newRead more
