Professors' super waterproof surfaces cause water to bounce like a ball
2014-05-20
In a basement lab on BYU's campus, mechanical engineering professor Julie Crockett analyzes water as it bounces like a ball and rolls down a ramp.
This phenomenon occurs because Crockett and her colleague Dan Maynes have created a sloped channel that is super-hydrophobic, or a surface that is extremely difficult to wet. In layman's terms, it's the most extreme form of water proof.
Engineers like Crockett and Maynes have spent decades studying super-hydrophobic surfaces because of the plethora of real-life applications. And while some of this research has resulted in ...
Termite genome lays roadmap for 'greener' control measures
2014-05-20
WEST LAFAYETTE, Ind. - A team of international researchers has sequenced the genome of the Nevada dampwood termite, providing an inside look into the biology of the social insect and uncovering new genetic targets for pest control.
Michael Scharf, a Purdue University professor of entomology who participated in the collaborative study, said the genome could help researchers develop control strategies that are more specific than the broad-spectrum chemicals conventionally used to treat termite infestations.
"The termite genome reveals many unique genetic targets that can ...
Fairy circles apparently not created by termites after all
2014-05-20
This news release is available in German. Leipzig. For several decades scientists have been trying to come up with an explanation for the formation of the enigmatic, vegetation-free circles frequently found in certain African grassland regions. Now researchers have tested different prevailing hypotheses as to their respective plausibility. For the first time they have carried out a detailed analysis of the spatial distribution of these fairy circles – and discovered a remarkably regular and spatially comprehensive homogenous distribution pattern. This may best be explained ...
Fossils prove useful in analyzing million year old cyclical phenomena
2014-05-20
Research conducted at the University of Granada has shown that the cyclical phenomena that affect the environment, like climate change, in the atmosphere-ocean dynamic and, even, disturbances to planetary orbits, have existed since hundreds of millions of year ago and can be studied by analysing fossils.
This is borne out by the palaeontological data analysed, which have facilitated the characterization of irregular cyclical paleoenvironmental changes, lasting between less than 1 day and up to millions of years.

Improved computer simulations enable better calculation of interfacial tension
2014-05-20
Computer simulations play an increasingly important role in the description and development of new materials. Yet, despite major advances in computer technology, the simulations in statistical physics are typically restricted to systems of up to a few 100,000 particles, which is many times smaller than the actual material quantities used in typical experiments. Researchers therefore use so-called finite-size corrections in order to adjust the results obtained for comparatively small simulation systems to the macroscopic scale. A team of researchers from Johannes Gutenberg ...
Particles near absolute zero do not break the laws of physics after all
2014-05-20
In theory, the laws of physics are absolute. However, when it comes to the laws of thermodynamics—the science that studies how heat and temperature relate to energy—there are times where they no longer seem to apply. In a paper recently published in EPJ B, Robert Adamietz from the University of Augsburg, Germany, and colleagues have demonstrated that a theoretical model of the environment's influence on a particle does not violate the third law of thermodynamics, despite appearances to the contrary. These findings are relevant for systems at the micro or nanometer scale ...
Busting rust with light: New technique safely penetrates top coat for perfect paint job
2014-05-20
WASHINGTON, May 20, 2014 – To keep your new car looking sleek and shiny for years, factories need to make certain that the coats of paint on it are applied properly. But ensuring that every coat of paint—whether it is on a car or anything else—is of uniform thickness and quality is not easy.
Now researchers have developed a new way to measure the thickness of paint layers and the size of particles embedded inside. Unlike conventional methods, the paint remains undamaged, making the technique useful for a variety of applications from cars to artifacts, cancer detection ...
Pine bark substance could be potent melanoma drug
2014-05-20
A substance that comes from pine bark is a potential source for a new treatment of melanoma, according to Penn State College of Medicine researchers.
Current melanoma drugs targeting single proteins can initially be effective, but resistance develops relatively quickly and the disease recurs. In those instances, resistance usually develops when the cancer cell's circuitry bypasses the protein that the drug acts on, or when the cell uses other pathways to avoid the point on which the drug acts.
"To a cancer cell, resistance is like a traffic problem in its circuitry," ...
Flu vaccines in schools limited by insurer reimbursement
2014-05-20
AURORA, Colo. (May 20, 2014) – School-based influenza vaccine programs have the potential to reach many children at affordable costs and with parental support, but these programs are limited by low rates of reimbursement from third-party payers, according to recently published study results by researchers from the University of Colorado School of Medicine.
A school-based flu vaccine program in the Denver Public Schools was effective at reaching nearly one-third of the students, but billing and reimbursement issues posed significant problems for administrators of the program.

Study shows how streptococcal bacteria can be used to fight colon cancer
2014-05-20
Researchers at Western University (London, Canada) have shown how the bacteria primarily responsible for causing strep throat can be used to fight colon cancer. By engineering a streptococcal bacterial toxin to attach itself to tumour cells, they are forcing the immune system to recognize and attack the cancer.
Kelcey Patterson, a PhD Candidate at Western and the lead author on the study, showed that the engineered bacterial toxin could significantly reduce the size of human colon cancer tumours in mice, with a drastic reduction in the instances of metastasis. By using ...
Parents of overweight kids more likely to give schools failing grades for fighting obesity
2014-05-20
ANN ARBOR, Mich. – Parents – especially those of overweight children – give schools a failing grade for efforts to encourage healthy habits that combat childhood obesity, according to a new poll from the University of Michigan.
According to the latest University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health, parents with at least one overweight child (25 percent of all parents in the poll) were more likely to give schools a failing grade of D or F for obesity-related efforts than parents of normal-weight children.

Students swayed by 'relaxing, fun' image of hookah smoking ignore health harms
2014-05-20
PITTSBURGH, May 20, 2014 – Educational campaigns meant to dissuade college students from initiating hookah tobacco smoking may be more successful if they combat positive perceptions of hookah use as attractive and romantic, rather than focusing solely on the harmful components of hookah tobacco smoke, a new University of Pittsburgh School of Medicine study found.
The research, supported by the National Cancer Institute, examined the sequence of events around which university students first smoke tobacco from a hookah, also known as a water pipe, in an effort to determine ...
Women repeatedly short-changed in case of premature ejaculation
2014-05-20
Premature ejaculation is one of the most common sexual disorders in men. But it is not just the men who suffer; it also causes increased psychological strain and stress in women, as a new survey conducted by Andrea Burri, a clinical psychologist at the University of Zurich, reveals. Around 40 percent of over 1,500 women polled from Mexico, Italy and South Korea indicated that ejaculation control is very important for satisfactory intercourse. It is not the short duration of the act of lovemaking that is primarily regarded as the main source of sexual frustration by the ...

E-cigarette use for quitting smoking is associated with improved success rates
2014-05-20
People attempting to quit smoking without professional help are approximately 60% more likely to report succeeding if they use e-cigarettes than if they use willpower alone or over-the-counter nicotine replacement therapies such as patches or gum, finds a large UCL (University College London) survey of smokers in England. (1) The results were adjusted for a wide range of factors that might influence success at quitting, including age, nicotine dependence, previous quit attempts, and whether quitting was gradual or abrupt.
The study, published in Addiction, surveyed 5,863 ...
