With the globalization of our food supply, food safety issues are a major concern for both public health and for the food industry. Media and industry warn consumers of major recalls and problems with food items, but do consumers listen? In this new article researchers demonstrated that consumers are reluctant to respond to food safety risks if the recommendations interfere with their existing habits.
New data describes how an experimental drug can stop life-threatening muscle wasting (cachexia) associated with advanced cancers and restore muscle health. The experimental agent, known as AR-42 while in testing, was tested in preclinical studies.
The damaging effects of carbon dioxide emissions from tourism could eventually be eliminated if travelers paid just US$11 per trip, according to a new study. Global tourism is largely dependent on fossil fuel energy, and emits more carbon dioxide than than all but five countries of the world. Recent estimates conclude that tourism, including transport, accommodation, and leisure activities contributed close to 5 percent of total human-made emissions of carbon dioxide worldwide.
A simple, rapid way to treat an immune-related disorder in mice has been identified by researchers, an approach that could eventually help multiple sclerosis patients after further research.
Older people with visual impairment can report feeling dizzy and falling. A new study found that after routine cataract surgery, the improved vision led to patients experiencing significantly less dizziness, although they did not experience fewer falls.
Don't have room for dessert? The bacteria in your gut may be telling you something. Twenty minutes after a meal, gut microbes produce proteins that can suppress food intake in animals, reports a study. The researchers also show how these proteins injected into mice and rats act on the brain reducing appetite, suggesting that gut bacteria may help control when and how much we eat.
Simply oscillating its fins is all a flounder, a flat fish, needs to do to resuspend sand and quickly disappear beneath it to hide. By discovering the physics at play, researchers are hoping to provide a new flounder-inspired solution to a common technological challenge: the resuspension of granular material within a fluid.
Astronomers have identified a dying star and intergalactic gas entering the Milky Way.
A new type of shopper -- the 'sport shopper' -- has been identified by researchers, for whom shopping is akin to athletic competition. They describe the sport shopper as someone who can afford to purchase items at full price, but instead bargain hunts for the thrill of out-smarting the retail system -- versus bargain shoppers who look for deals out of necessity.
A remarkably detailed animation of the movement of the densest and coldest water in the world around Antarctica has been produced using data generated on Australia's most powerful supercomputer, Raijin.
The power of the sharing economy in shaking up traditional industries can be harnessed to help financially struggling consumers, according to new research.
Swinging a bat at a 90-mph fastball requires keen visual, cognitive and motor skills. But how do diverse brain networks coordinate well enough to hit the ball? A new study suggests the human brain's aptitude and versatility can be credited in large part to 'connector hubs,' which filter and route information.
Scientists drilling into the ocean floor have, for the first time, found out what happens when one tectonic plate first gets pushed under another. The international expedition drilled into the Pacific ocean floor and found distinctive rocks formed when the Pacific tectonic plate changed direction and began to plunge under the Philippine Sea Plate about 50 million years ago.
Biologists have succeeded in inducing one species of flatworm to grow heads and brains characteristic of another species of flatworm without altering genomic sequence. The work reveals physiological circuits as a new kind of epigenetics -- information existing outside of genomic sequence -- that determines large-scale anatomy.
The enormous, solitary leatherback sea turtle spends most of its long life at sea. After hatching and dispersing across the world's oceans, only the female leatherbacks return to their natal beaches to lay clutches of eggs in the sand. A new study offers fresh insights into their nesting choices and will help efforts to prevent the extinction of this globally endangered giant of the sea, researchers said.
A number of antiviral drugs are licensed and widely used for the treatment of specific viral infections in humans. Potential new agents are also being investigated that it is hoped will overcome limitations of the current options, which include a narrow antiviral spectrum, ineffectiveness against latent virus infections, development of drug-resistance and toxic side effects.
A 'dinosaur' fossil originally discovered on Prince Edward Island, Canada, has been shown to have steak knife-like teeth, and researchers have changed its name to Dimetrodon borealis -- marking the first occurrence of a Dimetrodon fossil in Canada.
Vivid holographic images and text can now be produced by means of an ordinary inkjet printer. This new method is expected to significantly reduce the cost and time needed to create the so-called rainbow holograms, commonly used for security purposes -- to protect valuable items, such as credit cards and paper currency, from piracy and falsification.
A group of people with fatal H1N1 flu died after their viral infections triggered a deadly hyperinflammatory disorder in susceptible individuals with gene mutations linked to the overactive immune response, according to a study. Researchers suggest people with other types of infections and identical gene mutations also may be prone to the disorder, known as reactive HLH (rHLH), or hemophagocytic lymphohistiocytosis.
Since the earliest times, laughter and humor have performed important functions in human interaction. Jokes give us control over laughter and are therefore a way to elicit these positive effects intentionally. In order to comprehend why some jokes are perceived as funny and others are not, researchers investigated the cognitive mechanism underlying laughter and humor.
