Why Americans can't buy some of the best sunscreens

2015-05-27
(Press-News.org) With summer nearly here, U.S. consumers might think they have an abundance of sunscreen products to choose from. But across the Atlantic, Europeans will be slathering on formulations that manufacturers say provide better protection against the sun's damaging rays -- and skin cancer -- than what's available stateside, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.

Marc S. Reisch, a senior correspondent at C&EN, reports that sunscreens on the U.S. market do protect users from some ultraviolet-A and -B rays. But there are eight sunscreen molecules approved for use in Europe that could boost the effectiveness of products in the U.S. and also give manufacturers more flexibility in making their lotions. Some have been in line for FDA approval since 2002.

Why the hold-up? In Europe, sunscreen molecules are considered cosmetic ingredients. In the U.S., they are subject to the same scrutiny as over-the-counter drugs, which go through a more rigorous review process than cosmetics. More than 10 years ago, the FDA introduced a streamlined process to speed up the review of sunscreens from overseas to bring them to the U.S. market. But the products' makers are still waiting for approval, and some have given up.

Telemedicine exams result in antibiotics as often as regular exams, study finds

2015-05-27
Patients treated for an acute respiratory infection by a doctor on a telephone or live video are as likely to be prescribed an antibiotic as patients who are treated by a physician face-to-face for the same illness, according to a new RAND Corporation study. However, the patients treated virtually were more likely to be prescribed a broad-spectrum antibiotic -- concerning since overuse of the drugs increases costs and contributes to antibiotic resistance, according to the study. Researchers say both treatment settings had high rates of inappropriate prescribing for ...

Autism and rare childhood speech disorder often coincide

2015-05-27
Some children with autism should undergo ongoing screenings for apraxia, a rare neurological speech disorder, because the two conditions often go hand-in-hand, according to Penn State College of Medicine researchers. Over the course of a three-year study, 64 percent of children initially diagnosed with autism were found to also have apraxia. The study also showed that the commonly used Checklist for Autism Spectrum Disorder (CASD) accurately diagnoses autism in children with apraxia. "Children with apraxia have difficulty coordinating the use of their tongue, lips, ...

Experiment confirms quantum theory weirdness: ANU media release

Experiment confirms quantum theory weirdness: ANU media release
2015-05-27
The bizarre nature of reality as laid out by quantum theory has survived another test, with scientists performing a famous experiment and proving that reality does not exist until it is measured. Physicists at The Australian National University (ANU) have conducted John Wheeler's delayed-choice thought experiment, which involves a moving object that is given the choice to act like a particle or a wave. Wheeler's experiment then asks - at which point does the object decide? Common sense says the object is either wave-like or particle-like, independent of how we measure ...

Physicists solve quantum tunneling mystery: ANU media release

Physicists solve quantum tunneling mystery: ANU media release
2015-05-27
An international team of scientists studying ultrafast physics have solved a mystery of quantum mechanics, and found that quantum tunneling is an instantaneous process. The new theory could lead to faster and smaller electronic components, for which quantum tunneling is a significant factor. It will also lead to a better understanding of diverse areas such as electron microscopy, nuclear fusion and DNA mutations. "Timescales this short have never been explored before. It's an entirely new world," said one of the international team, Professor Anatoli Kheifets, from The ...

Protein scaffold

Protein scaffold
2015-05-27
This news release is available in Japanese. Right before a cell starts to divide to give birth to a daughter cell, its biochemical machinery unwinds the chromosomes and copies the millions of protein sequences comprising the cell's DNA, which is packaged along the length of the each chromosomal strand. These copied sequences also need to be put back together before the two cells are pulled apart. Mistakes can lead to genetic defects or cancerous mutations in future cell generations. Just like raising a building requires scaffolding be erected first, cells ...

Omitting market risk factor creates critical flaw in case-shiller home price indices

2015-05-27
The method used to calculate Standard & Poor's Case-Shiller Home Price Indices, the most trusted benchmark for U.S. residential real estate prices, contains a flaw that likely could lead to misstating its monthly estimates, according to a newly published study led by faculty at Florida Atlantic University. The paper published in the Journal of Real Estate Research identifies an important deficiency in the Weighted Repeated Sales (WRS) method developed by economists Karl Case and Robert Shiller, which compares repeat sales of the same homes in an effort to study home ...

Hip fractures in the elderly caused by falls, not osteoporosis

2015-05-27
Anti-osteoporotic medication is not an effective means for preventing hip fractures among the elderly, concludes a study recently published in the BMJ. Proximal femoral fractures (i.e., hip fractures) occur in the world at a rate of 1.5 million per year, or 7,000 per year in Finland. As most such fractures occur among older people, their number is expected to grow as the population ages. Hip fractures often lead to permanently reduced mobility, quality of life and general health, as well as result in significant social costs. Since the early 1990s, anti-osteoporotic ...

Challenging students benefit from limit setting

2015-05-27
The teacher's interaction style can either foster or slow down the development of math skills among children with challenging temperaments. This was shown in the results of the study "Parents, teachers and children's learning" carried out at the University of Jyväskylä, Finland. Ph.D. Jaana Viljaranta, along with her colleagues, studied the role of teachers' interaction styles in academic skill development among children with different temperamental characteristics. A child's challenging temperament may show up in the classroom, for example, as low task-orientation ...

The analogy that builds human thought

2015-05-27
When Niels Bohr hypothesised his model of atom with the electrons orbiting the nucleus just like satellites orbit a planet, he was engaging in analogical reasoning. Bohr transferred to atoms the concept of "a body orbiting another", that is, he transferred a relation between objects to other, new objects. Analogical reasoning is an extraordinary ability that is unique to the human mind, is not seen in animals (except very rarely in primates) and that forms the basis of highly sophisticated human thoughts. Scientists have wondered about the origin of this cognitive function: ...

Experiments in the realm of the impossible

Experiments in the realm of the impossible
2015-05-27
Jena (Germany) March 1938: The Italian elementary particle physicist Ettore Majorana boarded a post ship in Naples, heading for Palermo. But he either never arrives there - or he leaves the city straight away - ever since that day there has been no trace of the exceptional scientist and until today his mysterious disappearance remains unresolved. Since then, Majorana, a pupil of the Nobel Prize winner Enrico Fermi, has more or less been forgotten. What the scientific world does remember though is a theory about nuclear forces, which he developed, and a very particular elementary ...
