Our genetic information is stored in DNA, tiny strands of nucleic acid that contain instructions for the functioning of our bodies. To express this genetic data, our DNA is copied into RNA molecules, which then translate the instructions into proteins that perform tasks in our cells. Several years ago, scientists discovered a new type of RNA molecule. Unlike all other known RNAs, this molecule is circular, and was labeled circular RNA. Although circRNA molecules are abundant, little has been known about how they are produced. Moreover, little has been known about the ...

WHITE PLAINS, NY, SEPT. 18, 2014 -- Only about half of all pregnant women in the U.S. get a flu shot each season, leaving thousands of moms-to-be and their babies at increased risk of serious illness. "Getting a flu shot should be a routine part of prenatal care," said Edward McCabe, MD, March of Dimes chief medical officer. "Health care providers should offer their pregnant patients a flu shot each year and if they don't, then women should ask for it." A report by the U.S. Centers for Disease Control and prevention presented today by the National Foundation for ...

SEPTEMBER 18 —In war-torn Syria, five of six World Heritage sites now "exhibit significant damage" and some structures have been "reduced to rubble," according to new high-resolution satellite image analysis by the nonprofit, nonpartisan American Association for the Advancement of Science (AAAS). The AAAS analysis, offering the first comprehensive look at the extent of damage to Syria's priceless cultural heritage sites, was completed in partnership with the University of Pennsylvania Museum of Archaeology and Anthropology's Penn Cultural Heritage Center (PennCHC) and ...

Hurricane Polo still appears rounded in imagery from NOAA's GOES-West satellite, but forecasters at the National Hurricane Center expect that to change. NOAA's GOES-West satellite captured data on Hurricane Polo on Sept. 18 at 10:15 a.m. EDT. An image using that data was created by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The image showed thunderstorms wrapping tightly around the center of the storm while one broken band of thunderstorms extended to the northwest, while the other appeared on the eastern side of the center ...

Dartmouth researchers and their colleagues have built the first smartphone app that automatically reveals students' mental health, academic performance and behavioral trends. In other words, your smartphone knows your state of mind -- even if you don't -- and how that affects you. The StudentLife app, which compares students' happiness, stress, depression and loneliness to their academic performance, also may be used in the general population – for example, to monitor mental health, trigger intervention and improve productivity in workplace employees. "The StudentLife ...

The fall foliage season that prompts millions of Americans to undertake jaunts into the countryside each year could come much later and possibly last a little longer within a century, according to new research. Climate change could postpone fall leaf peeping in some areas of the United States as summer temperatures linger later into the year, Princeton University researchers report in the journal Global Ecology and Biogeography. For instance, the paper birch — a popular foliage tree that is the state tree of New Hampshire — could change color one to three weeks later ...

Life is rarely simple. From crop yields to disease risks, the biological characteristics people care most about are usually those considered "complex traits." Just as for height—the textbook example of a complex trait—attributes like risk for a particular human disease are shaped by multiple genetic and environmental influences, making it challenging to find the genes involved. To track down such genes, geneticists typically mate two individuals that differ in key ways—for example, a large mouse and a small mouse—and then study their descendents, looking for genes that ...

ALEXANDRIA, Va.—Sept. 18, 2014—Many Americans across racial and ethnic groups describe losing eyesight as potentially having the greatest impact on their day-to-day life, more so than other conditions including: loss of limb, memory, hearing and speech (57% of African-Americans, 49% of non-Hispanic whites, 43% of Asians and 38% of Hispanics). When asked which disease or ailment is the worst that could happen to them, blindness ranked first among African-Americans followed by AIDS/HIV. Hispanics and Asians ranked cancer first and blindness second, while Alzheimer's disease ...

CHAPEL HILL, N.C. – Individuals living in disadvantaged neighborhoods have worse musculoskeletal pain outcomes over time after stressful events such as motor vehicle collision than individuals from higher socioeconomic status neighborhoods, even after accounting for individual characteristics such as age, sex, income, education, and employment status. These were the findings of a multi-site research study led by Samuel McLean, MD, MPH, associate professor of anesthesiology and emergency medicine at the University of North Carolina School of Medicine. The results of the ...

According to a simulation of the impact of climate change on agricultural production over the course of the 21st century, carried out by researchers led by Professor Wolfram Mauser at LMU's Department of Geography, some two-thirds of all land potentially suitable for agricultural use is already under cultivation. The study indicates that climate change will expand the supply of cropland in the high latitudes of the Northern hemisphere (Canada, Russia, China) over the next 100 years. However, in the absence of adaptation measures such as increased irrigation, the simulation ...

This news release is available in German. In ecology, disease tolerance is defined as a host strategy not to fight a pathogen tooth and nail, but rather tolerate it to live (and survive) better in the long term. One key feature of tolerance is that the disease only progresses very slowly – if at all – even if the host carries a high pathogen load. Roland Regoes, a senior scientist at ETH Zurich's Institute of Theoretical Biology, has now transferred this approach to HIV. He set about investigating whether there are infected people who are more tolerant of the HI virus ...

New Rochelle, NY, September 18, 2014–An Emergency Room Decision-Support (ERDS) program can significantly reduce ER visits and hospital admissions among older adults on Medicare. This could have important economic implications, helping to reduce the nearly 33% of avoidable ER visits that contribute to about $18 billion in unnecessary healthcare costs each year. Details of a successful ERDS program that had a positive return on investment are published in an article in Population Health Management, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article ...

The ability to acquire and creatively manipulate spoken language is unique to humans. "The genetic changes that occurred over the past 6 million years of human evolution to make this possible are largely unknown, but Foxp2 is the best candidate gene we now have," says Wolfgang Enard, Professor of Anthropology and Human Biology at LMU. In his efforts to understand the molecular biological basis of language Enard has now taken an important step forward. The results of his latest study, undertaken in collaboration with scientists at several universities, including the Massachusetts ...

This eruption occurred just before the 1815 Tambora volcanic eruption which is famous for its impact on climate worldwide, with 1816 given memorable names such as 'Eighteen-Hundred-and-Froze-to-Death', the 'Year of the Beggar' and the 'Year Without a Summer' because of unseasonal frosts, crop failure and famine across Europe and North America. The extraordinary conditions are considered to have inspired literary works such as Byron's 'Darkness' and Mary Shelley's Frankenstein. However, the global deterioration of the 1810s into the coldest decade in the last 500 years ...

Anyone who has seen the movies of Neil Armstrong's first bounding steps on the moon couldn't fail to be intrigued by his unusual walking style. But, contrary to popular belief, the astronaut's peculiar walk was not the result of low gravity. Wyle Science, Engineering and Technology scientist John De Witt explains that the early space suits were not designed for walking, so the astronauts adapted their movements to the restrictions of the suit. Michael Gernhardt, the head of NASA's Extravehicular Activity Physiology, Systems and Performance Project, wants to learn more about ...

A wild berry native to North America may strengthen the effectiveness of a chemotherapy drug commonly used to treat pancreatic cancer, reveals research published online in the Journal of Clinical Pathology. The study by researchers at King's College Hospital and the University of Southampton suggests that adding nutraceuticals to chemotherapy cycles may improve the effectiveness of conventional drugs, particularly in hard to treat cancers, such as pancreatic cancer. The team tested the effectiveness of extract of chokeberry (Aronia melanocarpa) in killing off cancer ...

New evidence will be presented at the first Global Violence Reduction Conference in Cambridge this week which shows that homicide rates have been declining since the mid-1990s in many parts of the world - in some cases dramatically. Nations as diverse as Estonia, Hong Kong, South Africa, Poland, and Russia have seen average recorded homicide rates drop by 40% or more in the course of just 15 years. Out of 88 countries where trend data could be found, 67 showed a decline and only 20 showed an increase between 1995 and 2010, a new analysis of data from the United Nations ...

Positron emission tomography/computed tomography (PET-CT) is more accurate than conventional CT scanning in measuring response to treatment and predicting survival in patients with follicular lymphoma, and should be used routinely in clinical practice, according to new research published in The Lancet Haematology. "Our findings have important implications for patients with follicular lymphoma, a common and usually slow-growing lymphoma. Compared to conventional CT scanning, PET-CT is more accurate in mapping-out the lymphoma, and better identifies the majority of patients ...

The magnificent plumage of the peacock may not be quite the sacrifice to love that it appears to be, University of Leeds researchers have discovered. Dr Graham Askew, from the University's School of Biomedical Sciences, filmed five Indian peacocks taking off using two high-speed video cameras to try to work out what price male birds pay for carrying the spectacular iridescent feathers they use in displays to attract females. "These feathers weigh about 300g and can exceed 1.5m, so it's expected that the male birds would be making a significant sacrifice in their flight ...

Scientists at the University of Leeds think we may be able to drown deadly bacteria in their own paperwork. A research team in the University's Astbury Centre for Structural Molecular Biology has identified for the first time how the "paper shredder" that keeps the bacteria E. coli on top of its day job works. Now the group are looking for ways to jam the mechanism and leave E. coli and similar bacteria in filing hell. Dr Kenneth McDowall, Associate Professor in Molecular Microbiology, who led the research, said: "If we block the 'shredder' using genetics in the ...

Historically, spaceflight has been reserved for the very healthy. Astronauts are selected for their ability to meet the highest physical and psychological standards to prepare them for any unknown challenges. However, with the advent of commercial spaceflight, average people can now fly for enjoyment. The aerospace medicine community has had very little information about what medical conditions or diseases should be considered particularly risky in the spaceflight environment, as most medical conditions have never been studied for risk in space — until now. The aerospace ...

Curtin University research that monitors the volume of water in the Nile River Basin will help to level the playing field for more than 200 million North-East Africans who rely on the river's water supply. Despite being arguably the longest river in the world, winding through nine different countries, the Nile River is shallow and has a low volume, making its water precious, particularly to those countries located downstream. Curtin Associate Professor Joseph Awange, Department of Spatial Sciences, has been monitoring extractions or additions of water to the Nile River, ...

Children of college-educated parents eat more vegetables and drink less sugar, according to a new study from the University of British Columbia. But it's still not enough, the study goes on to say, as all kids are falling short when it comes to eating healthier at school The research suggests a parent's educational attainment, an indicator of socioeconomic status, may inform a child's diet. The study found Vancouver school children whose parents completed some post-secondary education were 85 per cent more likely to eat vegetables during the school week than those with ...

Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that most would have an optimistic outlook on life. In fact some dogs are distinctly more pessimistic than others, research from the University of Sydney shows. "This research is exciting because it measures positive and negative emotional states in dogs objectively and non-invasively. It offers researchers and dog owners an insight into the outlook of dogs and how that changes," said Dr Melissa Starling, from the Faculty of Veterinary Science. Her PhD research findings are published ...
