Erratics in Antarctica
March 31, 2011 07:36 AM - Andy Soos, ENN
A team from the University of Leeds and Aberystwyth University has returned from the Antarctica with exciting new information on the behavior of the giant Antarctic Ice Sheet. The Antarctic Ice Sheet is of exceptional interest to geoscientists due to its size and location, which mean that it reacts quickly and dynamically to climate change. The team of four found that the ice sheet had expanded and then retreated across neighboring James Ross Island several times over the last 25,000 years. The findings are crucial for understanding the thickness and extent of the ice sheet through time, and so its past and future contributions to sea level rise.
Big Problems in the Malaysian Forests

Nowhere is the problem of deforestation greater than in the tropical regions of the world. Specifically, Southeast Asia, which has vast tracts of primal rain forests, is at risk from excessive logging. Recently, governments in that region have come under pressure from environmentalists to conserve what forests they have left. Officials in the state of Sarawak, the Malaysian region of Borneo, have said that 70 percent of their forest cover has been preserved. However, after a review using Google Earth images, indications are that deforestation is much more widespread than is being claimed.
What is Green?
March 30, 2011 08:10 AM - Andy Soos, ENN
Green science or products can be loosely defined as the term for any application of science, knowledge or technology towards improving the relationship between human technology involvement and the impact this has on the environment and natural resources. It is a broad category, in that it can cover many different facets of technology and human development. With more and more environmentally conscious consumers trying to choose green products, American Chemical Society scientists reported today that the first reality check has revealed that the ingredients in those products may come from a surprising source —— petroleum, rather than natural plant-based sources.
Finding Puts New Emphasis on the Benefits of Jogging
March 29, 2011 10:05 AM - David A Gabel, ENN
Since the fitness revolution, physical activity has been promoted as an effective way to combat obesity and heart disease. Currently, walking is the number one recommended activity among both the young and old. However, new research from the University of Bristol has found that running and jogging are also important for building strong bones in children. It has also found that gentle exercise like walking has little effect on bone strength, even over a longer period. Walking offers little protection against the risk of osteoporosis later in life.

An aphrodisiac is a substance that increases sexual desire. The name comes from Aphrodite, the Greek goddess of sexuality and love. Throughout history, many foods, drinks, and behaviors have had a reputation for making sex more attainable and/or pleasurable. However, from a historical and scientific standpoint, the alleged results may have been mainly due to mere belief by their users that they would be effective (the placebo effect. Few have studied their true effects. However, try adding ginseng and saffron to your diet. Both are proven performance boosters, according to a new scientific review of natural aphrodisiacs conducted by University of Guelph researchers. Indulge in wine and chocolate, too, but know that their amorous effects are likely all in your head. Stay away from the more obscure Spanish fly and Bufo toad. While purported to be sexually enhancing, they produced the opposite result and can even be toxic.

Aging is the accumulation of changes in an organism or object over time. Aging in humans refers to a process of physical, psychological, and social change. Some dimensions of aging grow and expand over time, while others decline. Reaction time, for example, may slow with age, while knowledge of world events and wisdom may expand. Research shows that even late in life potential exists for physical, mental, and social growth and development. With that said for some people getting old means losing quality of life and wellness. Does gardening contribute to quality of life and increased wellness for older adults? Researchers from the Texas A&M and Texas State Universities asked these questions in a survey of people aged 50 and older. The survey revealed some compelling reasons for older adults to get themselves out in the garden.
Does Religion Make People Gain Weight?

People can pray to lose weight, but it turns out that more devout religious people often have a higher chance of gaining weight. According to a new study from Northwestern University, young adults who participate in religious activities are fifty percent more likely to become obese by middle age, compared to those with no religious involvement.
That Euphoric Feeling
March 25, 2011 08:18 AM - Andy Soos, ENN
For most people not sleeping well leads to being the person most likely to be avoided the next morning. A lesser known side effect of sleep deprivation is short-term euphoria, which can potentially lead to poor judgment and addictive behavior, according to new research from the University of California, Berkeley. Researchers at UC Berkeley and Harvard Medical School studied the brains of healthy young adults and found that their pleasure circuitry got a big boost after a missed night’s sleep. But that same neural pathway that stimulates feelings of euphoria, reward and motivation after a sleepless night may also lead to risky behavior, their study suggests.

A magic pill for controlling obesity is a dream that many have. Researchers exploring human metabolism at the University of California, San Francisco, have uncovered a handful of chemical compounds that regulate fat storage in worms, offering a new tool for understanding obesity and finding future treatments for diseases associated with obesity. Such compounds may allow chemical control of obesity. As described in a paper published this month in the journal Nature Chemical Biology, the team took armies of microscopic worms called C. elegans and exposed them to thousands of different chemical compounds. Giving these compounds to the worms, they discovered, basically made them skinnier or fatter without affecting how they eat, grow, or reproduce.
Ready To Eat Meat: Healthy?
March 23, 2011 04:29 PM - Andy Soos, ENN
What is better to eat, in terms of health, a hot dog (made from what?) or chicken? If given the choice between eating a hot dog or enjoying some rotisserie chicken, consider the hot dog at least according to some research out of Kansas State. That's because hot dogs, as well as pepperoni and deli meats, are relatively free of carcinogenic compounds, according to their research. But it's a not-so-happy ending for bacon and rotisserie chicken -- especially chicken skin -- because both have higher levels of cancerous material.
