A group of scientists has used deep ocean-floor drilling and experiments to show that volcanic rocks off the West Coast and elsewhere might be used to securely imprison huge amounts of globe-warming carbon dioxide captured from power plants or other sources. In particular, they say that natural chemical reactions under 78,000 square kilometers (30,000 square miles) of ocean floor off California, Oregon, Washington and British Columbia could lock in as much as 150 years of U.S. CO2 production.

Interest in so-called carbon sequestration is growing worldwide. However, no large-scale projects are yet off the ground, and other geological settings could be problematic. For instance, the petroleum industry has been pumping CO2 into voids left by old oil wells on a small scale, but some fear that these might eventually leak, putting gas back into the air and possibly endangering people nearby.


Remnants of the bacterium that causes stomach ulcers, Helicobacter pylori, (H. pylori) have been discovered in gastric tissue from North American mummies.

A study of human remains believed to predate Columbus' discovery of the New World has shown for the first time that H. pylori infection occurred in native populations, according to research published in BMC Microbiology.

As well as stomach ulcers, H. pylori causes gastritis, duodenitis, and cancer. It is a helix-shaped bacteria that is believed to be transmitted by the ingestion of food or water contaminated with faecal matter.


Nine out of ten regular food items aimed specifically at children have a poor nutritional content – because of high levels of sugar, fat or sodium - according to a detailed study of 367 products published in the July issue of the UK-based journal Obesity Reviews.

Just under 70 per cent of the products studied - which specifically excluded confectionery, soft drinks and bakery items - derived a high proportion of calories from sugar. Approximately one in five (23 per cent) had high fat levels and 17 per cent had high sodium levels. Despite this, 62 per cent of the foods with poor nutritional quality (PNQ) made positive claims about their nutritional value on the front of the packet.

"Children's foods can now be found in virtually every section of the supermarket and are available for every eating experience" says Professor Charlene Elliott from the University of Calgary, Canada, and a Trustee of the Canadian Council of Food and Nutrition.

Listen to science instead of Tiger Woods on golf? Sheer madness.

But golfers who heed the advice of instructors to keep their heads perfectly still while putting may be hampering their game, according to a study in the July issue of the Journal of Motor Behavior that examined coordination patterns.

Tim Lee, professor of kinesiology at McMaster University and a golfer himself, says the findings run contrary to conventional wisdom, or at least conventional golf wisdom.
 

The putting stroke is used more frequently than any other during a round of golf, regardless of skill. In 2007, putts represented 41.3 per cent of total strokes taken by members of the PGA tour, and 40 percent for members of the LPGA.



Israelis and Palestinians working together? Indeed, when it comes to combating tuberculosis.

Tuberculosis - or TB - is a deadly infectious bacterial disease that usually attacks the lungs. Acknowledged as a disease of crowds, it is transmitted from human to human living in close contact.

Dating back thousands of years, tuberculosis was well known in antiquity. However, according to Spigelman, it is still the biggest killer even today. One-third of the world's current population has been infected by tuberculosis, resulting, in recent years, in approximately three million deaths per year.

Plant sterols have been touted as an effective way to lower cholesterol and reduce the risk of heart disease. However, a research study in the July JLR has uncovered that these compounds do have their own risks, as they can accumulate in heart valves and lead to stenosis.

Aortic valve stenosis (AS) results from cholesterol accumulation in the valve between the left ventricle and aorta; this impedes the flow of blood and puts extra pressure on the heart. About 2% of individuals over 65 (and over 5% of those over 85) have AS, and as the population ages, it is becoming an increasing problem.

Plant sterols can block the absorption of dietary cholesterol into the body, and as such high vegetable diets and/or plant sterol supplements are often used to alleviate high cholesterol. However, although plant sterols themselves are poorly absorbed, they can enter the body, so Satu Helske and colleagues examined whether plant sterols can also accumulate in aortic valves.
