'Fishing expedition' nets nearly tenfold increase in number of sequenced virus genomes

COLUMBUS, Ohio - Using a specially designed computational tool as a lure, scientists have netted the genomic sequences of almost 12,500 previously uncharacterized viruses from public databases. The finding doubles the number of recognized virus genera - a biological classification one step up from species - and increases the number of sequenced virus genomes available for study almost tenfold. The research group studies viruses that infect microbes, and specifically bacteria and archaea, single-cell microorganisms similar to bacteria in size, but with a different evolutionary ...

Rural medicare beneficiaries receive less follow-up care

August 14, 2015- Medicare patients in rural areas have lower rates of follow-up care after leaving the hospital--which may place them at higher risk of emergency department (ED) visits and repeat hospitalizations, according to a study in the September issue of Medical Care. The journal is published by Wolters Kluwer. "This study provides evidence of lower rates of post-discharge follow-up care, and higher ED use for Medicare beneficiaries in rural settings," comments lead author Matthew Toth, PhD, MSW. The research was conducted while Dr. Toth was at University of North ...

Vitamin D in teens: Don't overdo it, bad things might happen

ROCHESTER, Minn. -- Dosing obese teens with vitamin D shows no benefits for their heart health or diabetes risk, and could have the unintended consequences of increasing cholesterol and fat-storing triglycerides. These are the latest findings in a series of Mayo Clinic studies in childhood obesity. Seema Kumar, M.D., a pediatric endocrinologist in the Mayo Clinic Children's Center, has been studying the effects of vitamin D supplementation in children for 10 years, through four clinical trials and six published studies. To date, Dr. Kumar's team has found limited benefit ...

'Brainy' mice raise hope of better treatments for cognitive disorders

It sheds light on the molecular underpinnings of learning and memory and could form the basis for research into new treatments for age-related cognitive decline, cognitive disorders such as Alzheimer's disease and schizophrenia, and other conditions. The researchers altered a gene in mice to inhibit the activity of an enzyme called phosphodiesterase-4B (PDE4B), which is present in many organs of the vertebrate body, including the brain. In behavioural tests, the PDE4B-inhibited mice showed enhanced cognitive abilities. They tended to learn faster, remember events ...

Newfound Jupiter-like exoplanet might hold the key to the rise of solar systems

Astronomers have spied a new alien world that they believe strikingly resembles a young Jupiter. Using a new instrument, the Gemini Planet Imager, they spotted 51 Eridani b, still warm and luminous from its formation. But what can this distant exoplanet, orbiting a star approximately 100 light years away, teach us about the solar system Jupiter calls home? "51 Eridani b is so young, it actually 'remembers' its formation in some sense," said Bruce Macintosh, of the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) at Stanford University, in an interview ...

Higher intelligence score means better physical performance

New research reveals a distinct association between male intelligence in early adulthood and their subsequent midlife physical performance. The higher intelligence score, the better physical performance, the study reveals. The Center for Healthy Aging and the Department of Public Health, University of Copenhagen, are behind this new study. We would all like to stay independent, as we get older. In order to succeed, we need to be in good physical shape. This includes being able to cope with everyday physical activities such as getting dressed and carrying our own shopping. ...

Young minds think alike -- and older people are more distractible

'Bang! You're Dead', a 1961 episode of Alfred Hitchcock Presents, continues to surprise - but not just with the twist in its tale. Scientists at the University of Cambridge have used the programme to show that young people respond in a similar way to events, but as we age our thought patterns diverge. In a study published today in the journal Neurobiology of Aging, the researchers also report that older people tended to be more easily distracted than younger adults. Age is believed to change the way our brains respond and how its networks interact, but studies looking ...

Meat food waste has greater negative environmental impact than vegetable waste

COLUMBIA, Mo. - Approximately 31 percent of food produced in the U.S., or 133 billion pounds of food worth $162 billion, was wasted in 2011 according to the United States Department of Agriculture (USDA). Now, University of Missouri researchers have found that the type of food wasted has a significant impact on the environment. Although less meat is wasted (on average) compared to fruits and vegetables, the researchers found that significantly more energy is used in the production of meat compared to the production of vegetables. This wasted energy is usually in the form ...

Research examines relationship between autism and creativity

New research has found that people with high levels of autistic traits are more likely to produce unusually creative ideas. Psychologists from the University of East Anglia (UEA) and University of Stirling examined the relationship between autistic-like traits and creativity. While they found that people with high autistic traits produced fewer responses when generating alternative solutions to a problem - known as 'divergent thinking' - the responses they did produce were more original and creative. It is the first study to find a link between autistic traits and the ...

Titanium rings proving problematic for emergency care doctors

Rings made of titanium--an increasingly popular alternative to gold and silver--are giving emergency doctors a headache because they are so difficult to prize off swollen fingers, reveals a case study published online in Emergency Medicine Journal. But now help is at hand, thanks to the ingenuity of plastic surgeons. The popularity of titanium rings is growing because the metal is light yet strong, extremely durable, and doesn't cause skin allergies. But a swollen finger caused by ring constriction is a relatively common problem in emergency care. And if not dealt ...
