Sensitive parenting can boost premature children's school performance
2013-07-31
Sensitive parenting helps protect against the negative effects of being born prematurely on children's school success, a new study has found.
Children born prematurely are at risk of a variety of neurological impairments which can mean they are more likely to need special educational support when they reach school age.
But a new study led by the University of Warwick shows that parents of very preterm and very low birthweight (VP/VLBW) children can increase their child's academic achievement through sensitive and cognitively stimulating parenting.
Researchers looked ...
Progress in using ethanol to make key raw material now produced from oil

Studying the emotions which cause opinions to change
2013-07-31
Social phenomena fascinate with their complexity, but are not easily understood. Pawel Sobkowicz, an independent researcher based in Warsaw, Poland, has developed a model to study the dynamics of normal people, called 'agents', and their response to a given piece of information, depending on their emotional state. In a study about to be published in EPJ B, the author shows that opinion dynamics differ depending on whether the agent is agitated or not.
Key social questions of interest have been the object of previous studies using physics tools. The field of magnetic interactions ...
New protein discovered with vast potential for treatment of cancer and other diseases
2013-07-31
In cancer research, discovering a new protein that plays a role in cancer is like finding a key and a treasure map: follow the clues and eventually there could be a big reward. At least that's the hope from a new study published in the journal Nature that discovered a novel protein called ceramide-1 phosphate transport protein (CPTP) -- a finding that could eventually lead to the development of new drugs to treat a variety of cancers and other conditions involving inflammation and thrombosis, or blood clotting.
The identification of CPTP was the result of an international ...

Sediment trapped behind dams makes them 'hot spots' for greenhouse gas emissions
2013-07-31
With the "green" reputation of large hydroelectric dams already in question, scientists are reporting that millions of smaller dams on rivers around the world make an important contribution to the greenhouse gases linked to global climate change. Their study, showing that more methane than previously believed bubbles out of the water behind small dams, appears in ACS' journal Environmental Science & Technology.
Andreas Maeck and colleagues point out that the large reservoirs of water behind the world's 50,000 large dams are a known source of methane. Like carbon dioxide, ...

2013-07-31
Brooklyn, N.Y.—The latest in a series of experiments testing the ability of robots to influence live animals shows that bio-inspired robots can not only elicit fear in zebrafish, but that this reaction can be modulated by alcohol. These findings may pave the way for new methodologies for understanding anxiety and other emotions, as well as substances that alter them.
Maurizio Porfiri, associate professor of mechanical and aerospace engineering at the Polytechnic Institute of New York University (NYU-Poly) and Simone Macrì, a collaborator at the Istituto Superiore di Sanità ...
First experimental signs of a New Physics beyond the Standard Model
2013-07-31
The Standard Model, which has given the most complete explanation up to now of the universe, has gaps, and is unable to explain phenomena like dark matter or gravitational interaction between particles. Physicists are therefore seeking a more fundamental theory that they call "New Physics", but up to now there has been no direct proof of its existence, only indirect observation of dark matter, as deduced, among other things, from the movement of the galaxies.
A team of physicists formed by the professor of Physics at Universitat Autònoma de Barcelona (UAB) Joaquim Matias, ...
Key factors for wireless power transfer
2013-07-31
WASHINGTON D.C., July 31, 2013 -- What happens to a resonant wireless power transfer system in the presence of complex electromagnetic environments, such as metal plates? A team of researchers explored the influences at play in this type of situation, and they describe in the American Institute of Physics' journal AIP Advances how efficient wireless power transfer can indeed be achieved in the presence of metal plates.
The team discovered that resonance frequency matching, alignment of the magnetic field, and impedance matching are the most important factors for efficient ...
Binding together repelling atoms
2013-07-31
Basic chemistry tells us that a bond between atoms can form if it is energetically more favorable for the atoms to stick together than staying apart. This fundamentally requires an attractive force between the atoms. However, new theoretical predictions show that the combination of a repelling force and controlled noise from an environment can also have the surprising effect of leading to a bound state, although one with quite exotic properties. The research team consisting of Harvard postdoc Mikhail Lemeshko and former Harvard postdoc Hendrik Weimer* report their results ...
The pathway to potato poisons
2013-07-31
In 1924, Science magazine reported on a fatal case of potato poisoning: James B. Matheney of Vandalia, Illinois, had gathered about one and a half bushels of tubers, which had turned green due to sunlight exposure. Two days after eating the potatoes, most of his family -- wife, two daughters and four sons -- showed symptoms of poisoning; the only exceptions were James himself, who didn't eat the potatoes, and a breast-fed baby boy. His wife, aged 45, died a week later, followed by their 16-year-old daughter. The other five members of the family recovered.
Although such ...
Gene decoding obeys road traffic rules
2013-07-31
One of life's most basic processes -- transcription of the genetic code -- resembles road traffic, including traffic jams, accidents and a police force that controls the flow of vehicles. This surprising finding, reported recently by Weizmann Institute researchers in Nature Communications, might facilitate the development of a new generation of drugs for a variety of disorders.
Transcription indeed involves a step resembling the motion of a vehicle: Enzymes "ride" along gene "tracks," creating molecules that will later be translated into the various proteins involved ...
Guided growth of nanowires leads to self-integrated circuits
2013-07-31
Researchers working with tiny components in nanoelectronics face a challenge similar to that of parents of small children: teaching them to manage on their own. The nano-components are so small that arranging them with external tools is impossible. The only solution is to create conditions in which they can be "trusted" to assemble themselves.
Much effort has gone into facilitating the self-assembly of semiconductors, the basic building blocks of electronics, but until recently, success has been limited. Scientists had developed methods for growing semiconductor nanowires ...

Using gold and light to study molecules in water
2013-07-31
Thanks to a new device that is the size of a human hair, it is now possible to detect molecules in a liquid solution and observe their interactions. This is of major interest for the scientific community, as there is currently no reliable way of examining both the behavior and the chemical structure of molecules in a liquid in real time.
Developed at Boston University by Hatice Altug and her student Ronen Adato, the process brings together infrared detection techniques and gold nanoparticles. It could potentially make a whole new class of measurements possible, which ...

New therapy improves life span in melanoma patients with brain metastases, SLU researchers find
2013-07-31
ST. LOUIS -- In a retrospective study, Saint Louis University researchers have found that patients with melanoma brain metastases can be treated with large doses of interleukin-2 (HD IL-2), a therapy that triggers the body's own immune system to destroy the cancer cells.
The study that was recently published in Chemotherapy Research and Practice, reviews cases of eight patients who underwent this therapy at Saint Louis University.
John Richart, M.D., associate professor of internal medicine at SLU and principal investigator of the study, first treated a patient with ...
Cross-country collaboration leads to new leukemia model
2013-07-31
Eight years ago, two former Stanford University postdoctoral fellows, one of them still in California and the other at the Harvard Stem Cell Institute (HSCI) in Cambridge, began exchanging theories about why patients with leukemia stop producing healthy blood cells. What was it, they asked, that caused bone marrow to stop producing normal blood-producing cells?
And after almost a decade of bicoastal collaboration, Emmanuelle Passegué, now a professor in the Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research at the University of California, San ...
