Ecological tourism has no effect on the presence of large mammals in the Amazon, according to a study that for the first time compares the biological diversity of ecotourism zones with that of protected areas. Furthermore, it can help to protect the biodiversity of areas that are not officially protected yet are vital in the ecological framework. Since the UN began to promote ecological tourism at the end of the 1980's as a way of protecting the environment without resorting to its economic exploitation, the debate as to whether ecotourism is really beneficial has remained ...

The Labor Department will be sharing information with nearly a dozen states, including New York's Attorney General, and the Internal Revenue Service in a push to crack down on businesses that cheat workers out of wages by misclassifying them as independent contractors. Wage and hour determinations vary greatly based on how a worker is characterized. By sharing information Labor officials will be able to target businesses that misclassify workers as independent contractors or non-employees to avoid paying the minimum wage and overtime pay. An employer can also avoid paying ...

Engineers at Virginia Polytechnic Institute and State University (VirginiaTech) have developed a robot that mimics the graceful motions of jellyfish so precisely that it has been named Robojelly. Developed for the Office of Naval Research in 2009, this vehicle was designed to conduct ocean underwater surveillance, enabling it potentially to detect chemical spills, monitor the presence of ships and submarines, and observe the migration of schools of fish. Recently, a team at VirginiaTech has improved the performance of this silicone swimmer, enabling it to better overcome ...

The heart's valves, which guarantee the unidirectional flow of blood from one chamber to another, are asymmetrical. For example, the two flaps of the heart's mitral valve – which regulates blood flow between the left atrium and the left ventricle – vary in size by up to 70 percent. This arrangement, says fluid mechanicist Marija Vukicevic from the University of Trieste (now a researcher at Clemson University), naturally drives blood flow along the lateral wall of the ventricle; from there, blood takes a smooth turn creating a large vortex that redirects the blood toward ...

Fervent debates continue over how states should rehabilitate juveniles convicted of crimes. Some believe that exposing kids to the rigors of prison life will help them understand the gravity of their actions and prevent future juvenile crime. Others maintain that jailing kids does nothing to deter crime and only advances the likelihood that they will be criminals as adults. Further, they believe that children are more likely to be abused while in confinement. A new report by the Annie E. Casey Foundation exemplifies these concerns. Entitled, "No Place for Kids: ...

Starting from the behavior of small flames in the laboratory, a team of researchers has gained new insights into the titanic forces that drive Type Ia supernova explosions. These stellar explosions are important tools for studying the evolution of the universe, so a better understanding of how they behave would help answer some of the fundamental questions in astronomy. Type Ia supernovae form when a white dwarf star – the left-over cinder of a star like our Sun – accumulates so much mass from a companion star that it reignites its collapsed stellar furnace and detonates, ...

Explosions of reactive gases and the associated rapid, uncontrolled release of large amounts of energy pose threats of immense destructive power to mining operations, fuel storage facilities, chemical processing plants, and many other industrial applications. To gain a better understanding of what's going on during these explosions, US Naval Research Laboratory research physicist Alexei Poludnenko, and Elaine Oran, senior scientist for reactive flow physics, teamed up with Sandia National Laboratories' Thomas Gardiner, principal member of technical staff, to study the ...

Research published in the European Journal of Epidemiology by Costanzo S, Di Castelnuovo de Gaetano G et al has sought to separate the effects of wine, beer or spirit drinking in relation to fatal and non-fatal cardiovascular events. The Italian authors carried out an updated meta-analysis on the relationship between wine, beer or spirit consumption and cardiovascular outcomes, using state-of-the-art statistical techniques. From 16 studies, results confirmed a J-shaped relationship between wine intake and reduced vascular risk, with maximal protection — an average 31% ...

Dividing small businesses in divorce can be difficult, complex, and of course...contentious. This is usually because the business is the family's largest asset, and the parties may have very different views about what it is worth, as well as their respective shares. One party may believe that the business is failing, and is only a fraction of its perceived value, while the other party may insist that it is a budding enterprise that is worth much more than is being explained. These views can be especially difficult if only one party primarily owns or operates the business, ...

University of Central Florida researchers, for the first time, have used stem cells to grow neuromuscular junctions between human muscle cells and human spinal cord cells, the key connectors used by the brain to communicate and control muscles in the body. The success at UCF is a critical step in developing "human-on-a-chip" systems. The systems are models that recreate how organs or a series of organs function in the body. Their use could accelerate medical research and drug testing, potentially delivering life-saving breakthroughs much more quickly than the typical ...

Every year, dozens of West Virginia workers lose their lives at factories, construction sites, mines and other jobsites. However, the latest figures show that 2010 was the worst year in recent history for worker fatalities. A Dangerous Year for West Virginia Workers In 2010, worker fatalities in West Virginia more than doubled compared to 2009. A total of 41 West Virginians lost their lives in work-related incidents in 2009, while a startling 95 workers were killed in 2010. This increase forced a tragic loss on 54 more grief-stricken families, leaving them only the ...

Underride accidents, which occur when a car hits the back of a truck and slides underneath it, are among some of the deadliest accidents on America's roads. Studies show that 350 people around the country are killed each year from underrides -- and those who do survive sustain long-term, devastating injuries. According to a study conducted by the Insurance Institute for Highway Safety (IIHS), these types of accidents may be prevented when rear impact guards are used on trucks -- which can save those in passenger vehicles because they prevent the car from sliding underneath ...

A new formula that can predict future health costs more accurately than previous models could help guide commissioning budgets for general practices under the government's new Health Bill, finds a study published on bmj.com today. The model (known as the 'person based resource allocation' or PBRA) was developed to help allocate resources for commissioning hospital care to all general practices in England, based on the health needs of each individual registered in each practice. A team of researchers led by The Nuffield Trust set out to develop a formula that was accurate ...

Grey seals have different types of personality that affect the extent to which they guard and care for their young, according to new research. Researchers from Durham University and the University of St Andrews, looking at seal colonies in Scotland, found that seal mothers are often unpredictable and adopt a wide variation of mothering styles when it comes to checking on their pups. Some are very attentive while others are not, the researchers found. The Durham-St Andrews study shows, for the first time, the extent of personality differences in marine mammals in the ...

In a new study published this month in the Journal of the American Chemical Society, researchers with The University of Texas Health Science Center at San Antonio have pinpointed the cancer-fighting potential in the bat plant, or Tacca chantrieri. Susan Mooberry, Ph.D., leader of the Experimental Development Therapeutics Program at the Cancer Therapy & Research Center and a professor of pharmacology at the UT Health Science Center, has been working to isolate substances in the plant, looking for a plant-derived cancer drug with the potential of Taxol. Taxol, the first ...

Registration requirements and other restrictions placed on people convicted of sex crimes in Pennsylvania recently have been the subject of much debate in the Pennsylvania Legislature. Lawmakers are deciding whether to adopt provisions of the federal Adam Walsh Act that would tighten restrictions on sex offenders or to forgo federal funding in the form of law enforcement grants to avoid enacting federal rules that some believe would not serve Pennsylvania residents well. Supporters of the proposed sex-offender legislation say it would increase public safety and guarantee ...

The Consumer Products Safety Commission (CPSC) announced last month that nine manufacturers and distributors have initiated a voluntary recall of pourable gel fuels intended for use in outdoor firepots. The recall occurred after the CPSC received reports that at least 65 people suffered injuries when the fuel spontaneously combusted while they were pouring it into their firepots. So far, two people have died and 34 have been hospitalized with second- or third-degree burn injuries. Product Described as "Napalm-Like" The injuries occurred while consumers ...

Traffic congestion is something many of us deal with on a daily basis. When considering lost time and added fuel costs, it comes as little surprise that the collective effects of congestion cost Americans billions every year. However, according to a new study from AAA, the substantial costs of congestion pale in comparison to the cost of traffic accidents. The Economic Toll of Motor Vehicle Accidents More Than Triple That of Congestion In early November, AAA released a report that compared traffic congestion and automobile crashes in terms of economic impact for the ...

This press release is available in French. Montreal -- Too much fast food, poor meal choices and bad eating habits are causing more Canadians to be overweight or obese. Despite this trend, individuals who eat well are 20 per cent less likely to be obese, according to a study by Concordia University economists published in the Journal of Primary Care & Community Health. "The risk of being obese or overweight is directly related to bad eating habits such as skipping meals, eating away from home, high consumption of fast and processed foods, as well as low consumption ...

The clinical trial was random, regulated, double-blinded and broad-based. The drug was tested on 457 patients, aged 16-45, who had been diagnosed with Type 1 diabetes a short time before joining the trial. The trial took place in around 40 medical centers in Europe, Israel and South Africa. The patients in the trial were randomly assigned to one of two groups: One received the trial drug (DiaPep277®) through a subcutaneous injection once every three months, for a period of two years, while the control group was given a placebo in the same way. In addition, all of the patients ...

COLUMBIA, Mo. – While most people only gain about a pound of weight during the holiday season, that pound may never come off, increasing the likelihood of becoming overweight or obese and the risk of related health problems, according to a National Institutes of Health study. University of Missouri dietitians recommend families maintain healthy diet and exercise habits during the holiday season beginning with Thanksgiving. Donna Mehrle, registered dietitian and extension associate in the Department of Nutrition and Exercise Physiology, reminds people to consider ...

Authorities Break Up Maryland Child Pornography Ring In June, a Maryland man pled guilty to one count of interstate advertisement of child pornography. The man used a friend-sharing program to establish a child pornography network that shared over 10,000 images and photos of young boys with over 70 "buddies." Everyone in the network was encouraged to manufacture "fresh" material for the group. Those who did not were threatened with being kicked out. According to statements made by the man, he spent several hours a day making new videos for the ...
