When writing the abstracts for journal articles, most scientists receive similar advice: keep it short, dry, and simple. But a new analysis by University of Chicago researchers of over 1 million abstracts finds that many of these tips backfire, producing abstracts cited less than their long, flowery, and jargon-filled peers.
Urinary tract infections (UTIs) are common, and widespread antibiotic resistance has led to urgent calls for new ways to combat them. Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences report that an experimental drug that stabilizes a protein called HIF-1alpha protects human bladder cells and mice against a major UTI pathogen. The drug might eventually provide a therapeutic alternative or complement to standard antibiotic treatment.

Young HIV positive women are more likely to practice safer sex if they have an equitable perception of gender roles, according to new research involving the University of Southampton.
Offering a potential early intervention for Alzheimer’s disease (AD), researchers at University of California, San Diego School of Medicine and Cenna Biosciences, Inc. have identified compounds that block the production of beta amyloid peptides in mice.
Scientists report that a new study of HIV-infected men in Uganda has identified a temporary, but potentially troublesome unintended consequence of the procedure: a possible increased risk of infecting female sexual partners while circumcision wounds heal.
A demographic study of two endangered plants at Point Reyes National Seashore north of San Francisco shows that they favor recently disturbed open areas over areas that have established plant cover. The study strengthens the case for removing the beachgrass originally planted to stabilize the dunes and allowing the sand to move in response to storm surges and strong tides.

A new study shows a correlation between the number of city trees and overall income levels in seven U.S. cities.
Researchers need to find ways to measure how the changes in climate are affecting biodiversity. One of the best places to look may be down at our feet, at beetles. That`s because, as a McGill research team discovered after doing the first large-scale survey of Arctic beetles, these six-legged critters are not only abundant in number but also diverse in feeding habits and what they eat is closely linked to the latitude in which they are found.
A new study from the Santa Fe Institute confirms quantitatively that partisan disagreements in the U.S. Congress are worsening and that polarization is harmful to policy innovation.

Everyone knows that 60 is the new 50. But now, Warren Sanderson, a Professor of Economics at Stony Brook University, and Sergei Scherbov, a project leader at an Austrian research institute, have written an article about future population projections for Europe up to the year 2050 published in PLOS ONE, which shows that, counterintuitively, population aging is slower when life expectancy increase is faster – 60 really is the new 50.
Research by scientists at The University of Manchester has revealed that the colour of light has a major impact on how our body clock measures the time of day.
University of Utah scientists have uncovered patterns of DNA anomalies that predict a woman’s outcome significantly better than tumor stage. In addition, these patterns are the first known indicator of how well a woman will respond to platinum therapy. Published in the journal PLOS ONE, the patterns were discovered by using a new mathematical technique in the analysis of DNA profiles from the Cancer Genome Atlas, a national database containing data from hundreds of ovarian cancer patients.
Researchers at Johns Hopkins Medicine have transformed skin cells from patients with Lou Gehrig’s disease, or amyotrophic lateral sclerosis (ALS), into brain cells affected by the progressive, fatal disease and deposited those human-made cells into the first public ALS cell library, enabling scientists to better study the disease.

Researchers found enhanced rather than suppressed immune function in animals with increased biodiversity. Publishing online in the April 8, 2015, issue of PLOS ONE, the findings add to the growing understanding of the complex environment in the digestive tract and its role in maintaining health.
Northern Europeans in the Neolithic period initially rejected the practice of farming, which was otherwise spreading throughout the continent, a team of researchers has found. Their findings offer a new wrinkle in the history of a major economic revolution that moved civilizations away from foraging and hunting as a means for survival.
The significance of this work is its descriptions of alternative mechanisms by which tumors move and settle in new locations.

Research suggests that HIV induces age-associated changes to the DNA, which in turn lead to earlier onset of age-related illnesses such as some cancers, renal and kidney disease, frailty, osteoporosis and neurocognitive diseases by more than 14 years.
New research from UAB suggests that Corexit EC9500A, an oil-dispersal agentl, contributes to damage to epithelium cells within the lungs of humans and gills of marine creatures. The study also identifies an enzyme that is expressed in epithelial cells across species that has protective properties against Corexit-induced damage.

A molecular pathway known to suppress tumors appears to also be a major player in clearing cells of damaged proteins implicated in neurodegenerative diseases such as ALS and certain types of dementia, new research in roundworms and human cells suggests.
The little voice inside your head that tells you to eat, or stop eating, isn’t a little voice – it’s actually a cluster of about 10,000 specialized brain cells. And now, scientists have found tiny triggers inside those cells that give rise to this “voice”, and keep it speaking throughout life.
A major study published in PLOS One showed that women who are abused by their partner or ex-partner are much less likely to use contraception; this exposes them to sexually transmitted diseases and leads to more frequent unintended pregnancies and abortions. These findings could influence how physicians provide contraceptive counselling.
Research has discovered a role for prolactin, the hormone that stimulates milk production in nursing mothers, in the bond between parents. The study on cotton-top tamarins found a link between prolactin levels and sexual activity and cuddling among paired adults. Although this was a first for prolactin, it has previously been found for oxytocin, a hormone that stimulates childbirth and is linked to a range of pleasurable emotions.

The outcome of a duel between mathematical models supports the reigning theory of the genetics of altruism. Called inclusive fitness, it says altruism is competitive if it benefits relatives carrying the same gene as the selfless individual. Attacked by a Nature article published in 2010, it is defended by Washington University evolutionary biologist David Queller.
Using both robots and infants, an Indiana University cognitive scientist and collaborators have found that posture is critical in the early stages of acquiring new knowledge.
Rodents infected with a common parasite lose their fear of cats, resulting in easy meals for the felines. Now IU School of Medicine researchers have identified a new way the parasite may modify brain cells, possibly helping explain changes in the behavior of mice -- and humans.
