Rollover accidents pose the greatest risk of injury to drivers and occupants of trucks and SUVs. According to the National Highway Transportation Safety Administration (NHTSA) the number of serious injuries increases 33 percent when a car rolls over in a crash. When this happens, tremendous pressure is forced on passengers' heads and necks, thereby causing debilitating injuries. The NHTSA reports that 280,000 rollover accidents occur each year, and that 10,000 people die in these crashes annually. Rollover accidents are most common in sport utility vehicles and other ...

An artificial hip replacement consists of a prosthetic ball attached to the top of the femur which fits inside a socket implanted into the hip bone. While both the ball and socket can be composed of several materials, in artificial hips implanted into more than half a million Americans, both components are made out of metal. Metal-on-metal hip implants have caused a variety of problems for patients. Yet, despite the proliferation of products liability lawsuits and even recalls of certain devices -- including DePuy brand artificial hips that had been implanted in patients ...

We all trust airplane pilots, semi-truck drivers, subway operators and ship crews to be hyper-vigilant while flying, driving or sailing. To ensure their safety and ours, these "safety-sensitive workers" are federally required to submit to random drug and alcohol tests. The goal is to keep them sober and alert, while keeping everyone else around them alive. Unfortunately, a new study shows an increase in illegal drug use among these workers, putting the rest of us in danger for truck accidents and other serious crashes. Drug Use Up Based on a review of ...

A study carried out by VTT Technical Research Centre of Finland indicates that extreme weather conditions cost EU transport system at least €15 billion a year. Currently, the greatest costs incurred are from road accidents, with the associated material damage and psychological suffering. However, costs arising from accidents are expected to decrease in volume, though time-related costs attributable to delays are projected to increase. In part, this is due to climate change, whose impact on extreme weather phenomena was addressed in the study, and because of consequent costs. In ...

This press release is available in German. Max Planck scientists have found out that the olfactory system in hermit crabs is still underdeveloped in comparison to that of vinegar flies. While flies have a very sensitive sense of smell and are able to identify various odor molecules in the air, crabs recognize only a few odors, such as the smell of organic acids, amines, aldehydes, or seawater. Humidity significantly enhanced electrical signals induced in their antennal neurons as well as the corresponding behavioral responses to the odorants. The olfactory sense of vinegar ...

Reprogramming asthma-promoting immune cells in mice diminishes airway damage and inflammation, and could potentially lead to new treatments for people with asthma, researchers have found. The researchers were able to reprogram the asthma-promoting cells (called Th2 (T-helper 2) cells) after identifying an enzyme that modifies the DNA of these cells. The enzyme could be a target for the development of new treatments for chronic inflammatory diseases, in particular allergic asthma, caused by an excess of Th2 cells. Walter and Eliza Hall Institute researcher Dr Rhys Allan ...

A professor from the University of Southampton has called on doctors around the world to give patients with persistent dizziness a booklet of simple exercises, after new research has shown that it is a very cost effective treatment for common causes of the condition. Lucy Yardley, who has been researching dizziness for many years, will urge GPs at the international WONCA conference today (5 July) to ensure that the booklet is translated so that patients of all nationalities can benefit. Professor Yardley's urgent appeal comes after her study, funded by the National ...

One bit of digital information stored on a hard disk currently consists of about 3 million magnetic atoms. Researchers from Karlsruhe, Strasbourg, and Japan have now developed a mag-netic memory with one bit per molecule. By an electric pulse, the metal-organic molecule can be switched reliably between a conductive, magnetic state and a low-conductive, non-magnetic state. This novel correlation for molecules is now reported in the Nature Communications journal. (doi: 10.1038/ncomms1940) "The superparamagnetic effect prevents smaller bit sizes from being reached in a ...

International university students and water experts have converged at Nanyang Technological University (NTU) to form the backbone of an intellectual and research community on a scarce natural resource -- water. NTU hosted 24 international students from 10 countries in the last fortnight as they attended the inaugural GlobalTech Summer Camp to learn about Singapore's water story. Last week, the university also hosted the 4th GlobalTech Workshop gathering the top water experts to share and discuss this global problem. In addition, NTU's Nanyang Environment & Water Research ...

Selfish behaviour is a threat to successful coexistence and mutual cooperation. In many cases this human cooperation is based on punishing those who do not cooperate. There can be two different forms of punishment here: direct punishment by peers and institutionalised punishment by institutions like the police. Arne Traulsen, Torsten Röhl and Manfred Milinski from the Max Planck Institute for Evolutionary Biology in Plön conducted a behavioural experiment to study what form of punishment people prefer under which conditions. The scientists have demonstrated that people ...

In the prestigious international journal Religion, the Islamicist Stefan Reichmuth and the Latinist Reinhold Glei have published a joint paper on the concept of religion in the Koran. The RUB researchers show how, in Latin translations of the Koran, the religious notion changes – from "law" to "religion". The surprising finding: since the Middle Ages, the confrontation with the Islamic religious notion has constantly accompanied and possibly even promoted this change in Europe. Double meaning In their detailed philological study, the two scientists started by examining ...

In addition to previous studies, this research is also based on an experiment carried out by the Institute for Biocomputation and Physics of Complex Systems (BIFI) at the Universidad de Zaragoza, together with the Fundación Ibercivis and Universidad Carlos III de Madrid (UC3M), the largest study of its kind to date in real time regarding cooperation in society. It was carried out during this past December, with 1,200 Aragon secondary students participating, who interacted electronically in real time via a social conflict prototype known as the "Prisoner's Dilemma". This ...

Strawberries, the traditional summer treat associated with Wimbledon could be serving up some unexpected health benefits. Scientists at the University of Warwick have been studying the beneficial effects of strawberries on our cardiovascular health, particularly around how they prevent the development of heart disease and diabetes. Professor Paul Thornalley from Warwick Medical School heads the team that discovered extracts from strawberries positively activate a protein in our bodies called 'Nrf2' which is shown to increase antioxidant and other protective activities. ...

A*STAR scientists from the Institute of Molecular and Cell Biology (IMCB) and the Singapore Bioimaging Consortium (SBIC) have discovered a new signalling pathway that controls both obesity and atherosclerosis. The team demonstrated, for the first time, that mice deficient in the Wip1 gene were resistant to weight gain and atherosclerosis via regulation of the Ataxia telangiectasia mutated gene (ATM) and its downstream signalling molecule mTor. These groundbreaking findings were published in the journal Cell Metabolism on 3rd July and may provide significant new avenues ...

JUPITER, FL, July 5, 2012 – Scientists from the Florida campus of The Scripps Research Institute have identified a series of intricate biochemical steps that lead to the successful production of proteins, the basic working units of any cell. The study, which appears in the July 6, 2012 edition of the journal Cell, sheds light on the assembly of a structure called the ribosome, a large and complex protein-producing machine inside all living cells. Ribosomes are the targets of many commercially used antibiotics and represent a promising area of research because of the ...

Feeling full involves more than just the uncomfortable sensation that your waistband is getting tight. Investigators reporting online on July 5th in the Cell Press journal Cell have now mapped out the signals that travel between your gut and your brain to generate the feeling of satiety after eating a protein-rich meal. Understanding this back and forth loop between the brain and gut may pave the way for future approaches in the treatment and/or prevention of obesity. Food intake can be modulated through mu-opioid receptors (MORs, which also bind morphine) on nerves found ...

Most people call it the "art" of persuasion, but public health researchers at the University of Southern California (USC) are trying to pinpoint the "science" behind social influence. They hope a better understanding of human interactions — both face-to-face and online — can help prevent disease and promote general health. Whether the goal is to curb smoking at a local school or to reduce the spread of sexually transmitted diseases within a community, it is important to understand the social structure of the group and the dynamics of influence at play, says Thomas W. ...

MELBOURNE, FLA.—Climate change drove coral reefs to a total ecosystem collapse lasting thousands of years, according to a paper published this week in Science. The paper shows how natural climatic shifts stopped reef growth in the eastern Pacific for 2,500 years. The reef shutdown, which began 4,000 years ago, corresponds to a period of dramatic swings in the El Niño–Southern Oscillation (ENSO). "As humans continue to pump greenhouse gases into the atmosphere, the climate is once again on the threshold of a new regime, with dire consequences for reef ecosystems unless we ...

VIDEO: A blood clot within a mouse artery disappears following the injection of a clot-busting, shear-activated nanotherapeutic. The bright areas are fluorescent-labeled platelets. Click here for more information. Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a novel biomimetic strategy that delivers life-saving nanotherapeutics directly to obstructed blood vessels, dissolving blood clots before they cause ...

DURHAM, N.C. -- Although many areas of the human brain are devoted to social tasks like detecting another person nearby, a new study has found that one small region carries information only for decisions during social interactions. Specifically, the area is active when we encounter a worthy opponent and decide whether to deceive them. A brain imaging study conducted by researchers at the Duke Center for Interdisciplinary Decision Science (D-CIDES) put human subjects through a functional MRI brain scan while playing a simplified game of poker against a computer and human ...

The discovery is an important step toward therapies that aim to repair the brain not by introducing new stem cells but rather by spurring those that are already present into action, says the study's lead author Freda Miller of the University of Toronto-affiliated Hospital for Sick Children. The fact that it's a drug that is so widely used and so safe makes the news all that much better. Earlier work by Miller's team highlighted a pathway known as aPKC-CBP for its essential role in telling neural stem cells where and when to differentiate into mature neurons. As it happened, ...
