  • Tool helps public health agencies prioritize health risks
    Public health agencies across the globe are challenged with preventing the spread of chronic diseases while dealing with limited funds and devastating budget cuts. Now, a researcher has applied the Public Health Index model, a tool he designed that has been adopted by the Missouri Department of Health and Senior Services, to help the Brazilian government identify and prioritize health risks affecting its population.
  • Half of the most popular news on Twitter is not covered by traditional news media sources
    Half of the news that appears on Twitter as 'trending topics' goes unmentioned in the traditional news media, and when both sources carry it, 60 percent of the stories appear first on the social network. Those are some of the conclusions of a study which analyzes the dissemination of news on Twitter compared with the traditional media.
  • How bees naturally vaccinate their babies
    When it comes to vaccinating their babies, bees don't have a choice -- they naturally immunize their offspring against specific diseases found in their environments. Now for the first time, scientists have discovered how they do it. This opens the door for researchers to develop the first-ever vaccine for insects. This is particularly important for bees since they help keep fruit, nuts and vegetables in our diets and have been declining in numbers for six decades.
  • Agrarian settlements drive severe tropical deforestation across the Amazon
    Resettlement projects in the Amazon are driving severe tropical deforestation, according to new research. Widely hailed as a socially responsible and 'innocuous' strategy of land redistribution, agrarian reform settlements have been created throughout the Brazilian Amazon since the early 1970s at an unprecedented scale. But a new study reveals that these farmer resettlement projects are far from environmentally friendly or socio-economically beneficial.
  • Affordable genetic diagnostic technique for target DNA analysis developed
    A technique to analyze various target DNAs has been developed using an aptamer, a DNA fragment that can recognize and bind to a specific protein or enzyme.
  • Magnetism at nanoscale

  • Effects of spinach extract on satiety: Feel full, curb cravings
    A new study examines how consuming the concentrated extract of thylakoids found in spinach can reduce hunger and cravings. Thylakoids encourage the release of satiety hormones, which is very beneficial in slowing down fat digestion.
  • New cancer marker identified; possible therapeutic target for breast cancer
    Basal-like breast cancer (BLBC) is an aggressive form of breast cancer and is often referred to as "triple negative," which means it is not responsive to the common medical therapeutics. BLBC is more likely to metastasize -- or spread to different areas of the body -- quicker and earlier, and is associated with a poor prognosis. A new way to detect - and perhaps treat -- this deadly form of breast cancer has now been found, scientists report.
  • Perfectionism linked to burnout at work, school and sports, research finds
    Perfectionistic concerns have a positive relationship with overall burnout and symptoms of burnout, research has found. Perfectionistic concerns can create stress, interfere with relationships and more.
  • New insights on hurricane intensity, pollution transport
    As tropical storm Isaac was gaining momentum toward the Mississippi River in August 2012, researchers were dropping instruments from the sky above to study the ocean conditions beneath the storm. The newly published study showed how a downwelling of warm waters deepened the storm's fuel tank for a rapid intensification toward hurricane status. The results also revealed how hurricane-generated currents and ocean eddies can transport oil and other pollutants to coastal regions.
  • Starvation effects handed down for generations
    Starvation early in life can alter an organism for generations to come, according to a new study in nematodes. The epigenetic effects are a 'bet-hedging strategy.' Famine survivors are smaller and less fertile, and they acquire a toughness that lasts at least two generations. The mechanism of the epigenetic inheritance has not been identified, however.

    Tests of the experimental Ebola vaccine VSV-ZEBOV in over 7500 participants in Guinea suggest that the vaccine provides high protection against the disease as early as ten days after vaccination, in adults who have potentially been exposed to the virus by coming in close contact with a recently infected person.
  • Getting to the bottom of aging
    The question of why we age is one of the most fascinating questions for humankind, but nothing close to a satisfactory answer has been found to date. Scientists have now taken one step closer to providing an answer. They have conducted a study in which, for the first time, they have shown that a certain area of the cell, the so-called endoplasmic reticulum, loses its oxidative power in advanced age. If this elixir of life is lost, many proteins can no longer mature properly. At the same time, oxidative damage accumulates in another area of the cell, the cytosol. This interplay was previously unknown and now opens up a new understanding of aging, but also of neurodegenerative diseases such as Alzheimer's or Parkinson's.
  • Drinking at conception boosts diabetes risk for baby, study shows
    Babies conceived by women who drink alcohol around the time of conception face dramatically increased risks of type 2 diabetes and obesity in early middle age, a study has found.

The novel electrode requires about 70 times less silver than conventional silver grid electrodes, but possesses comparable electrical conductivity.
  • Parents inclined to misjudge child happiness based on personal feelings
    Parents' estimations of their children's happiness differ significantly from the child's own assessment of their feelings, according to a new study. Research showed parents of 10 and 11-year-olds consistently overestimated their child's happiness, while those with 15 and 16-year-olds were inclined to underestimate.
  • RNA-binding protein influences key mediator of cellular inflammation, stress responses
    RNA-binding proteins such as RC3H1 regulate the degradation of the mRNA molecules and thus prevent the production of specific proteins. Researchers have now shown that ROQUIN binds several thousand mRNA molecules. They demonstrated that ROQUIN also influences the gene regulator NF-kappaB, a key mediator of cellular inflammation and stress responses.
  • Shaping the hilly landscapes of a semi-conductor nanoworld
    Nanoscale worlds sometimes resemble macroscale roller-coaster style hills, placed at the tip of a series of hexagons. Surprisingly, these nanohills stem from the self-organization of particles -- the very particles that have been eroded and subsequently redeposited following the bombardment of semi-conductors with ion beams. Now, a new theoretical study constitutes the first exhaustive investigation of the redeposition effect on the evolution of the roughening and smoothing of two-dimensional surfaces bombarded by multiple ions.

    Research teams have proactively assembled an international group of 26 experts, including prominent genetic engineers and fruit fly geneticists, to unanimously recommend a series of preemptive measures to safeguard gene drive research.
  • California 'rain debt' equal to average full year of precipitation
    A new study has concluded California accumulated a debt of about 20 inches of precipitation between 2012 and 2015 -- the average amount expected to fall in the state in a single year. The deficit was driven primarily by a lack of air currents moving inland from the Pacific Ocean that are rich in water vapor.
  • How to become a T follicular helper cell
    Follicular helper Tcells (TFH cells), a rare type of immune cell that is essential for inducing a strong and lasting antibody response to viruses and other microbes, have garnered intense interest in recent years but the molecular signals that drive their differentiation had remained unclear. Now, a team of researchers has identified a pair of master regulators that control the fate of TFH cells.
  • Cancer patients lose faith in healthcare system if referred late by GP
    If it takes more than three trips to the GP to be referred for cancer tests, patients are more likely to be dissatisfied with their overall care, eroding confidence in the doctors and nurses who go on to treat and monitor them, a study shows.
  • Research explores future energy security of China
    China needs to reduce its dependence on coal and improve the range of fuels it uses if it is to have long term energy security, according to new research.

    Working with yeast and worms, researchers found that incorrect gene expression is a hallmark of aged cells and that reducing such “noise” extends lifespan in these organisms.
  • Study questions presence in blood of heart-healthy molecules from fish oil supplements
    The importance of a diet rich in fish oils -- now a billion dollar food-supplement industry -- has been debated for over half a century. A new study questions the relevance of fish oil-derived substances and their purported anti-inflammatory effects in humans.
  • Byproduct of intestinal bacteria may jeopardize heart health in patients with kidney disease
    Blood levels of TMAO, a byproduct generated from intestinal bacterial as they metabolize dietary nutrients, progressively increase with advancing severity of kidney disease. TMAO levels are dramatically reduced when kidney function is restored following kidney transplantation, researchers say, noting that high TMAO levels are linked with an increased risk of atherosclerosis and premature death in patients with chronic kidney disease.
  • Organic molecules on comets: Philae's first results from Churi prove surprising
    Organic molecules never previously observed in comets, a relatively varied structure on the surface but a fairly homogeneous interior, organic compounds forming agglomerates rather than being dispersed in the ice: these are just some of first results provided by Philae on the surface of comet Churi. These in situ findings, which contain a wealth of completely new information, reveal several differences in comparison with previous observations of comets and current models.
  • Research could lead to protective probiotics for frogs
    In research that could lead to protective probiotics to fight the 'chytrid' fungus that has been decimating amphibian populations worldwide, researchers have grown bacterial species from the skin microbiome of four species of amphibians.

  • Texting while driving bans save 19 lives per year
    On average, there was a 7 percent reduction in crash-related hospitalizations in states that have enacted bans on texting and driving, researchers say. Hospitalizations were reduced the most -- 9 percent -- among 22-64 year olds and those aged 65 and older.
  • Concussions most common during practice
    As high school and college athletes hit the fields and courts in pre-season practice, concussion awareness should be part of their education, experts say, as most concussions happen during practice and not during games.
  • An exceptional planetary system discovered in Cassiopeia
    Astronomers have teased out a secret planetary system hiding in the arms of Cassiopea, just 21 light years away from us. The remarkable system, named HD219134, hosts one outer giant planet and three inner super-Earths, one of which transits in front of the star. The transiting super-Earth has a density similar to the Earth. It is by far the closest transiting planet known today. It provides the ideal candidate for follow-up studies and a deeper understanding of planetary formation, internal composition, and atmospheres. The system is so close that astronomers already dream about taking pictures of the new "Stars."
  • Comets: Soft shell, hard core?
    Comet Churyumov-Gerasimenko poses new riddles: Surface material measurements performed by the Philae landing module indicate that the near surface material might have changed since its formation. Up to now, many researchers had assumed that it has remained in virtually the same state since its formation about 4.5 billion years ago.
  • Blocking PHD2 oxygen sensor inhibits breast cancer dissemination
    Reducing the expression of the PHD2 oxygen sensor impairs the ability of breast cancers to metastasize (spread) to other parts of the body, scientists have discovered. Breast cancer is the second leading cause of cancer death in women, primarily due to metastasis. These findings indicate that PHD2 inhibition may have valuable therapeutic potential.
