It can be a total surprise: car tires burst, sealing rings fail and even your dearly beloved panton chair or your freely oscillating plastic chair develops cracks and the material gets fatigued. The reason for this often sudden and unforeseen material failure is triggered by microcracks that may be found in any component. You may hardly see these cracks and they may grow fast or slow. This also applies to fractures in components made of plastic that can be elastically formed. Sealing rings or tires are made of these elastomers and they can withstand mechanical loads especially ...

HOUSTON -- (April 5, 2011) -- Some people collect stamps and coins, but when it comes to sheer utility, few collections rival the usefulness of Rice University researcher Michael Deem's collection of 2.6 million zeolite structures. Zeolites are materials -- including some natural minerals -- that act as molecular sieves, thanks to a Swiss-cheese-like arrangement of pores that can sort, filter, trap and chemically process everything from drugs and petroleum to nuclear waste. Zeolites are particularly useful as catalysts -- materials that spur chemical reactions. There ...

PHILADELPHIA – Two reports by addiction researchers at the University of Pennsylvania School of Medicine and the National Institute on Drug Abuse show a drastic shift in prescribing patterns impacting the magnitude of opioid substance abuse in America. The reports, published in JAMA, recommend a comprehensive effort to reduce public health risks while improving patient care, including better training for prescribers, pain management treatment assessment, personal responsibility and public education. The JAMA Research Report shows that there has been a drastic increase ...

In an unprecedented collaborative analysis published in the journal PLoS Biology, scientists from 49 nations demonstrated that the ability of reef fish systems to produce goods and services to humanity increases rapidly with the number of species. However, growing human populations hamper the ability of reefs to function normally, and counterintuitively, the most diverse reef fish systems suffer the greatest impairments from stressors triggered by human populations. The study documented that the extent of this distress is widespread and likely to worsen because 75% of the ...

Making DNA sequences being passed through nanochannels a thousand times thinner than a human hair to the point that they take on the form of diminutive spaghetti. This is an innovative technique, known as DNA stretching, and is one of the lines of research in which CIC microGUNE is working, and about which they have already published two scientific articles and are shortly to apply for a patent. The technique basically consists of the analysis of a single molecule of DNA, after stretching it, measuring its length and analysing its sequence. This novel technology could ...

Paris is a traditional focal point of the celebrations on Labour Day, known as La Fete du Travail in France. Everything in the city closes except the Eiffel Tower on May 1st, with parades and demonstrations taking place around the Place de la Bastille. Across Paris, the exchanging of lily of the valley is a well-known custom on La Fete du Travail. Florists throughout the French capital stock up on the flower in the days running up to the public holiday, as it is traditionally passed between friends and family members as a token of good luck. Individual traders ...

WINSTON-SALEM, N.C. – April 5, 2011 – Despite a growing number of cities instituting smoking bans across the country, hookah bars are cropping up everywhere – from chic downtown cafes to locations near college campuses, where they've found a loyal customer base in young adults. A new study done by researchers at Wake Forest Baptist Medical Center sheds light on the increasingly popular pastime, and the results are discouraging. "The popularity of hookah smoking among young adults is quite alarming given the potential for negative health effects," said Erin L. Sutfin, ...

As our bodies form, cells within the embryo divide and separate. Certain cells come together to form the outer layer, or ectoderm, of the early embryo, and give rise to tissue such as the skin and nervous system (spine, peripheral nerves and brain). Other cells come together to form the mesoderm or middle layer of the embryo, and eventually give rise to tissue like muscle, heart or bone. Once cells have been assigned to the different regions – mesoderm or ectoderm – a mysterious mechanism draws boundaries between them that mark their permanent separation. Any defect in ...

That the thyroid can be affected and that the kidneys in rare cases can be damaged are known side-effects of medication with lithium. Female patients who become pregnant are also advised against taking medicine containing lithium, as the substance can affect the foetus. "The amounts of lithium that the Latin American women are ingesting via their drinking water are perhaps a tenth of what a patient would take daily for bipolar disorder. But, on the other hand, they are absorbing this lithium all their lives, even from before birth", says occupational and environmental ...

It's been a puzzle why our two closest living primate relatives, chimpanzees and bonobos, have widely different social traits, despite belonging to the same genus. Now, a comparative analysis of their brains shows neuroanatomical differences that may be responsible for these behaviors, from the aggression more typical of chimpanzees to the social tolerance of bonobos. "What's remarkable is that the data appears to match what we know about the human brain and behavior," says Emory anthropologist James Rilling, who led the analysis. "The neural circuitry that mediates ...

For the first time, researchers have found five regions in the human genome that increase susceptibility to immunoglobulin A (IgA) nephropathy, a major cause of kidney failure worldwide — systematically identifying those that point to a tendency for IgA nephropathy, or a protection against it. "The study is unique in identifying the biological pathways that mediate IgA nephropathy, mapping the way for further study that may reveal practical targets for diagnosis and treatment," said Dr. Ali Gharavi, Division of Nephrology at Columbia University in New York City, the ...

New Orleans – Each year, more than 100,000 patients in the U.S. undergo implantation of a new implantable cardioverter defibrillator (ICD) for heart rhythm abnormalities. This number constitutes a 20-fold increase over the last 15 years. Current medical guidelines advocate discussion of end of life care of these medical devices, including deactivation, but many patients may not understand their options. Now, researchers at the University of Pennsylvania School of Medicine say that discussions should also address post-mortem donation of ICDs for product improvement or reuse ...

New York / Heidelberg, 6 April 2011 The arrays of fine adhesive hairs or 'setae' on the foot pads of many insects, lizards and spiders give them the ability to climb almost any natural surface. Research by James Bullock and Walter Federle from the University of Cambridge in England found that the different forces required to peel away these adhesive hairs from surfaces are what allows beetles to adhere to diverse surfaces, thereby reducing the risk of detachment. Their study, published online in the Springer journal Naturwissenschaften – The Nature of Science, reports ...

A search team led by the Woods Hole Oceanographic Institution (WHOI) has located the wreckage of Air France Flight 447 some 3,900 meters, or nearly 2.5 miles, below the surface of the Atlantic Ocean off Brazil's northeastern coast.
