Culminating an 8 year search, scientists at the RIKEN-MIT Center for Neural Circuit Genetics captured an elusive brain signal underlying memory transfer and, in doing so, pinpointed the first neural circuit for "oops" ? the precise moment when one becomes consciously aware of a self-made mistake and takes corrective action. The findings, published in Cell, verified a 20 year old hypothesis on how brain areas communicate. In recent years, researchers have been pursuing a class of ephemeral brain signals called gamma oscillations, millisecond scale bursts of synchronized ...

TORONTO – Baker's yeast is giving scientists a better understanding of drug interactions, which are a major cause of hospitalization and illness world-wide. When two or more medications are taken at the same time, one can suppress or enhance the effectiveness of the other. Similarly, one drug may magnify the toxicity of another. These types of interactions are a major cause of illness and hospitalization. However, there are severe practical limits on the practical scope of drug studies in humans. Limits come in part from ethics and in part from the staggering expense. ...

An international team led by King's College London and the San Francisco Veteran Affairs Medical Center (SFVAMC) has developed the first lab-grown epidermis – the outermost skin layer - with a functional permeability barrier akin to real skin. The new epidermis, grown from human pluripotent stem cells, offers a cost-effective alternative lab model for testing drugs and cosmetics, and could also help to develop new therapies for rare and common skin disorders. The epidermis, the outermost layer of human skin, forms a protective interface between the body and its external ...

LA JOLLA, CA— April 24, 2014 —A team led by scientists at The Scripps Research Institute (TSRI) working with the International AIDS Vaccine Initiative (IAVI) has discovered a new vulnerable site on the HIV virus. The newly identified site can be attacked by human antibodies in a way that neutralizes the infectivity of a wide variety of HIV strains. "HIV has very few known sites of vulnerability, but in this work we've described a new one, and we expect it will be useful in developing a vaccine," said Dennis R. Burton, professor in TSRI's Department of Immunology and Microbial ...

CAMBRIDGE, Mass. (April 24, 2014) – Closely resembling plump grains of wild rice set in motion, the three-banded panther worms swimming in disposable containers in Whitehead Institute Member Peter Reddien's lab hardly seem like the next big thing in regeneration. And yet, these little-studied organisms possess the ability to regenerate any part of their bodies and are amenable to molecular studies in the lab, making them a valuable addition to a field keen on understanding how mechanisms controlling regeneration have evolved over millennia and how they might be activated ...

New Rochelle, NY, April 24, 2014—D-ribose is a commercially important sugar used as a sweetener, a nutritional supplement, and as a starting compound for synthesizing riboflavin and several antiviral drugs. Genetic engineering of Escherichia coli to increase the bacteria's ability to produce D-ribose is a critical step toward achieving more efficient industrial-scale production of this valuable chemical, as described in an article in Industrial Biotechnology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Industrial Biotechnology ...

DALLAS – April 24, 2014 – Scientific research at UT Southwestern Medical Center previously discovered that the newborn animal heart can heal itself completely, whereas the adult heart lacks this ability. New research by the same team today has revealed why the heart loses its incredible regenerative capability in adulthood, and the answer is quite simple – oxygen. Yes, oxygen. It is well-known that a major function of the heart is to circulate oxygen-rich blood throughout the body. But at the same time, oxygen is a highly reactive, nonmetallic element and oxidizing agent ...

New research led by Alison Allan, PhD, a scientist at Western University and the Lawson Health Research Institute, shows why breast cancer often spreads or metastasizes to the lung. Breast cancer is the number one diagnosed cancer and the number two cause of cancer-related deaths among women in North America. If detected early, traditional chemotherapy and radiation have a high success rate, but once the disease spreads beyond the breast, many conventional treatments fail. In particular, the lung is one of the most common and deadly sites of breast cancer metastasis ...

Benefits often coexist with the negative and stressful outcomes for parents who have a child born with or later diagnosed with a life-limiting illness, says a recent study led by a researcher at the University of Waterloo. While the challenges are numerous and life-changing and stress levels high, the vast majority of parents who participated in the Waterloo-led research reported positive outcomes as well, a phenomenon known as posttraumatic growth. The findings appear in the most recent issue of the American Journal of Orthopsychiatry. "What is pivotal is the meaning ...

OAK RIDGE, Tenn., April 24, 2014 — Researchers at the Department of Energy's Oak Ridge National Laboratory have developed a new and unconventional battery chemistry aimed at producing batteries that last longer than previously thought possible. In a study published in the Journal of the American Chemical Society, ORNL researchers challenged a long-held assumption that a battery's three main components -- the positive cathode, negative anode and ion-conducting electrolyte -- can play only one role in the device. The electrolyte in the team's new battery design has ...

EAST LANSING, Mich. --- New research shows that cells are more resilient in taking care of their DNA than scientists originally thought. Even when missing critical components, cells can adapt and make copies of their DNA in an alternative way. In a study published in this week's Cell Reports, a team of researchers at Michigan State University showed that cells can grow normally without a crucial component needed to duplicate their DNA. "Our genetic information is stored in DNA, which has to be continuously monitored for damage and copied for growth," said Kefei Yu, ...

Depression affects more than one out of three survivors of critical illness, according to a Vanderbilt study released in The Lancet Respiratory Medicine, and the majority of patients experience their symptoms physically rather than mentally. It is one of the largest studies to investigate the mental health and functional outcomes of critical care survivors, according to lead author James Jackson, Psy.D., assistant professor of Medicine, and it highlights a significant public health issue, with roughly 5 million patients admitted to intensive care units (ICUs) in the United ...

CHAMPAIGN, Ill. — It is better to give than to receive – at least if you're an adolescent and you enjoy giving, a new study suggests. The study found that 15- and 16-year-olds who find pleasure in pro-social activities, such as giving their money to family members, are less likely to become depressed than those who get a bigger thrill from taking risks or keeping the money for themselves. The researchers detail their findings in the Proceedings of the National Academy of Sciences. The study focused on the ventral striatum, a brain region that regulates feelings of ...

Dust off those Bic ballpoints and college-ruled notebooks — research shows that taking notes by hand is better than taking notes on a laptop for remembering conceptual information over the long term. The findings are published in Psychological Science, a journal of the Association for Psychological Science. Walk into any university lecture hall and you're likely to see row upon row of students sitting behind glowing laptop screens. Laptops in class have been controversial, due mostly to the many opportunities for distraction that they provide (online shopping, browsing ...

Carbon offsetting initiatives could be improved with new insights into the make-up of tropical forests, a study suggests. Scientists studying the Amazon Basin have revealed unprecedented detail of the size, age and species of trees across the region by comparing satellite maps with hundreds of field plots. The findings will enable researchers to assess more accurately the amount of carbon each tree can store. This is a key factor in carbon offset schemes, in which trees are given a cash value according to their carbon content, and credits can be traded in exchange ...

The work has been published in the Scientific Reports journal. CSIC researcher Carles Lalueza-Fox, from the Institute of Evolutionary Biology (a joint centre of CSIC and Pompeu Fabra University-UPF), explains: "When the Y chromosome of three living Bourbons was decoded and we saw that it did not match with the DNA recovered from the pumpkin in 2010, we decided to sequence the complete genome and to make a functional interpretation in order to see if the blood could actually belong to Louis XVI". The functional genome analysis was based on two main points, the genealogical ...

Philadelphia, Pa. (April 24, 2014) - Contact lenses coated with an antimicrobial peptide could help to lower the risk of contact lens-related infections, reports a study in Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. Studies in animals and now humans support the biocompatibility and safety of lenses coated with the antimicrobial peptide melimine, according to the new research by Debarun Dutta, B.Optom, of The University of New South Wales, ...

WINSTON-SALEM, N.C. – April 24, 2014 – 'Take me out to the ballgame' doesn't exactly conjure up images of apple slices and kale chips. The more likely culprits include French fries, soda and the occasional box of Crackerjacks. Unfortunately for children who play youth baseball, eating unhealthy food during practices and games may be contributing to weight problems, according to researchers at Wake Forest Baptist Medical Center. The study, published in the current online edition of Childhood Obesity, found that high-calorie snacks and sugar-sweetened drinks dominate the ...

DURHAM, N.C. – Changes in managing patients before, during and after colorectal surgery cut hospital stays by two days and reduced readmission rates, according to researchers who led a study of the approach at Duke University Hospital. The practice, called enhanced recovery, is easier on patients before surgery, doing away with the fasting period and bowel evacuation that are typically prescribed. After surgery, patients are encouraged to eat and move about as soon as possible, leading to faster recoveries. Among findings published in the May 2014 issue of the journal ...

Ellen's (not her real name) adoptive parents weren't surprised when the school counselor suggested that she might have attention deficit hyperactivity disorder (ADHD). Several professionals had made this suggestion over the years. Given that homework led to one explosion after another, and that at school Ellen, who is eleven, spent her days jiggling up and down in her seat, unable to concentrate for more than ten minutes, it seemed a reasonable assumption. Yet her parents always felt that ADHD didn't quite capture the extent of Ellen's issues over the years. Fortunately ...

COLUMBIA, Mo. – Fairness is not always the most important priority for small retailers. In an international study, University of Missouri researchers found that some small retailers are less concerned about whether they are treated fairly by business suppliers than other factors, such as cash flow and company survival. Lisa Scheer, the Emma S. Distinguished Professor of Marketing in the MU Trulaske College of Business, notes that what retailers consider to be fair business practices differ greatly across cultures and situations. "It is presumed that fairness, however ...

CORVALLIS, Ore. – An Oregon State University researcher has found a relationship between motor skill deficiencies and the severity of the symptoms of autism spectrum disorder in very young children. The findings, believed to the be the first to show a direct relationship between motor skills and autism severity, indicate that development of fine and gross motor skills should be included in treatment plans for young children with autism, said Megan MacDonald, an assistant professor in OSU's College of Public Health and Human Sciences. "Recognizing those deficits really ...

WASHINGTON -- When the task at hand requires some imagination, taking a walk may lead to more creative thinking than sitting, according to research published by the American Psychological Association. "Many people anecdotally claim they do their best thinking when walking," said Marily Oppezzo, PhD, of Santa Clara University. "With this study, we finally may be taking a step or two toward discovering why." While at Stanford University's Graduate School of Education, Oppezzo and colleague Daniel L. Schwartz, PhD, conducted studies involving 176 people, mostly college ...

In 2009 the influenza pH1N1 virus caused the first flu pandemic in the 21st century. The virus reached Finland in May 2009 and killed more than 50 people in the country. Since 2011 the pH1N1 virus infects Finns mainly during flu epidemics (winter/spring seasons). Infections with influenza pH1N1 virus vary from asymptomatic to serious complicated illnesses. World Health Organization has recommended Tamiflu for treatment of patients with severe or progressive illness. The disadvantage of this drug is that it targets viral proteins which mutate quickly and the virus develops ...
