After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
The U.S. Centers for Disease Control and Prevention estimates that drug-resistant bacteria sicken two million U.S. residents annually and cause about 23,000 deaths. Federal officials have called combating antibiotic resistance a national priority. To aid in that effort, a second-generation antibiotic has shown early effectiveness against common bacterial infections that pose a serious health threat to children and adults. Researchers discovered it by changing the chemical structure of an old antibiotic named spectinomycin, a safe but weak drug first introduced in the 1960s.
A detailed analysis of the remains of a high-status Danish Bronze Age female, known as the Egtved Girl, has revealed information about her movements, what she ate, and where her clothes came from. The Egtved Girl, a 16–18 year old female, was discovered in the Danish village of Egtved in an oak coffin, calculated to have been buried around 3,400 years ago.
A new class of magnets that swell in volume when placed in a magnetic field also generate negligible amounts of wasteful heat during energy harvesting.This "Non-Joulian Magnetostriction" could change the way we think about a certain type of magnetism that has been in place since 1841, when physicist James Prescott Joule discovered that iron-based magnetic materials changed their shape but not their volume when placed in a magnetic field. This phenomenon is referred to as "Joule Magnetostriction," and since its discovery 175 years ago, all magnets have been characterized on this basis.
In 2003, while French youth protested American imperialism, 14,000 mostly elderly people were allowed to die in a heat wave. Heat waves kill a lot more people, it is believed, except they don't. Instead, an analysis of 74 million deaths in 384 locations across Australia, Brazil, Canada, China, Italy, Japan, South Korea, Spain, Sweden, Taiwan, Thailand, UK, and the USA found that cold weather kills about 20 times as many people as hot weather.
Scientists have found stone tools dating back 3.3 million years, long before the advent of modern humans, and by far the oldest such artifacts yet discovered. The tools, whose makers may or may not have been some sort of human ancestor, push the known date of such tools back by 700,000 years and may challenge the notion that our own most direct ancestors were the first to create new technology.The discovery is the first evidence that an even earlier group of proto-humans may have had the thinking abilities needed to figure out how to make sharp-edged tools. The stone tools mark "a new beginning to the known archaeological record," say the authors of a new paper about the discovery.
Researchers have confirmed strong warming in the upper troposphere, known colloquially as the tropospheric hotspot, long expected as part of the global warming hypothesis.
Though the tropospheric hotspot appears in many global climate models, the inability to detect it has been used to suggest climate change is not occurring as a result of increasing carbon dioxide emissions.
If you think of your 'sense of self', do you locate it in your heart or your brain? It can tell people a lot about your decision-making process. Obviously, advertising is one area. Messages targeted at people with independent self-construals (your head tells you buying this car is the right decision because it has good value) will work better for those people than messages targeted at people with interdependent self-construals (Your heart tells you buying this car is the right decision because it has the highest safety ratings for families.)
Our belief in evil influences our feelings about capital punishment, according to Donald Saucier, associate professor of psychology at Kansas State University and Russell Webster at St. Mary's College of Maryland.
They drew their conclusion after about 200 participants were given a summary of a case in which a murderer confessed to his crime. They then asked each participant about his or her support for different types of sentences, such as jail time with community service, jail time with the opportunity for parole, jail time without the possibility for parole and other options.
Our solar system started as a disk of microscopic dust, gas, and ice around the young Sun and the amazing diversity of planets, moons, asteroids, and comets came from this primitive dust.
NASA's Stardust mission has returned to Earth with samples of comet Wild 2, a comet that originated outside the orbit of Neptune and was subsequently kicked closer to Earth's orbit in 1974 when Jupiter's gravity altered Wild 2's orbit.
Many of us are familiar with electrolytic splitting of water from their school days: if you hold two electrodes into an aqueous electrolyte and apply a sufficient voltage, gas bubbles of hydrogen and oxygen are formed. If this voltage is generated by sunlight in a solar cell, then you could store solar energy by generating hydrogen gas.This is because hydrogen is a versatile medium of storing and using "chemical energy".
An international team, including archaeologists from the University of Southampton, has found evidence suggesting leprosy may have spread to Britain from Scandinavia.
The team, led by the University of Leiden, and including researchers from Historic England and the universities of Southampton, Birmingham, Surrey, and Swansea, examined a 1500 year old male skeleton, excavated at Great Chesterford in Essex, England during the 1950s.
The bones of the man, probably in his 20s, show changes consistent with leprosy, such as narrowing of the toe bones and damage to the joints, suggesting a very early British case. Modern scientific techniques applied by the researchers have now confirmed the man did suffer from the disease and that he may have come from southern Scandinavia.
At the 2015 American Urological Association annual meeting in New Orleans, Dr. Jonathan Harper will present the findings of an FDA-registered "first in humans" trial to non-surgically propel and expel kidney stones from the body.Harper and colleagues in the Department of Urology and Applied Physics Laboratory at the University of Washington have invented a new way to facilitate kidney stone passage or dislodge large obstructing stones, using ultrasound. Ultrasound technologies have been successfully used for many years on the International Space Station (ISS), primarily to perform imaging of the astronauts' eyes, bones, and internal organs.
