Helium: swollen stars, party balloons and squeaky voices | Dean Burnett :: There are increasing reports of an imminent helium shortage, but why should this be a concern? What is helium used for, apart from balloons? Quite a lot, as it happensHelium supplies are running low. This is cause for concern for some. Others might wonder what the fuss is about.The statement itself may seem bizarre in some respects. How can we be "running out" of the second most abundant element in the known universe? Mankind may have had a substantial impact on the planet's resources, but using up a quarter of all known matter? Even the most extreme environmentalist would have to agree that's a bit of an exaggeration. The atmosphere of Jupiter alone is about 10% helium. Let's not even get started on the sun. Obviously, the problem is we're running out of accessible helium, meaning stuff w...

Climate scientists must not advocate particular policies | Tamsin Edwards :: I became a climate scientist because I care about the environment, but we have a moral obligation to be impartialAs a climate scientist, I'm under pressure to be a political advocate. This comes mainly from environmentalists. Dan Cass, wind-farm director and solar advocate, preferred me not to waste my time debating "denialist morons" but to use political advocacy to "prevent climate catastrophe".Jeremy Grantham, environmental philanthropist, urged climate scientists to sound a "more desperate note … Be arrested if necessary." A concerned member of the public judged my efforts at public engagement successful only if they showed "evidence of persuasion".Others ask "what should we do?" At my Cheltenham Science Festival event Can we trust climate models? one of the audience asked what we th...<div id="medworm"><p><b><i>MedWorm Message:</i></b> Get the very latest Swine Flu news via the MedWorm <b><a href="http://www.medworm.com/rss/search.php?qu=%2Bswine+%2B%28influenza+flu%29&t=Swine+Flu&f=infectiousdiseases&r=Any&o=d" target ="_self">Swine Flu RSS news feed</a></b> - updated hourly from thousands of authoritative health and news sources.</p></div>

Buzzfeeds: the effects of colony collapse disorder and other bee news :: Concerned about the worldwide bee crisis? Introducing Buzzfeeds, a weekly analysis with our resident bee expertIn the past six years, more than 10m beehives have been wiped out from a mystery disease called colony collapse disorder. This destruction has serious implications on worldwide ecology and economy.Of the 100 crop species responsible for providing 90% of food worldwide, 71 are dependent on bee pollination, according to UN estimates (pdf). It's difficult to pinpoint the financial implications of this destruction, but the international body says pollination is worth between $37bn and $91bn, annually.Stories about the declining population and its effect on the environment trickle through the news cycle each week. To bring awareness to these stories and contextualize the issues, we wil...

Investing in cardiovascular research benefits economy :: Investing in cardiovascular disease research in Canada provides economic and societal benefits to Canadians, according to new research published in CMAJ Open. "Our main goal was to understand how much "bang" we were getting from our research "buck" and whether investing in cardiovascular disease research is worthwhile from a population health perspective," writes Dr. Claire de Oliveira, scientist and health economist with the Centre for Addiction and Mental Health (CAMH), Toronto, with coauthors. Cardiovascular disease is the number one cause of hospitalization and death in Canada...

With food safety bill, U.S. government will spend nearly $1 million per person to prevent food-borne illness deaths :: (NaturalNews) The recently-passed Food Safety Modernization Act, which was passed in order to prevent food-borne illness deaths in the USA, will cost $1.4 billion over the first five years. But nobody thinks about the economics of the issue. How many people are we going to save by spending this $1.4 billion, even assuming it works?To answer that question, let's look at the food illness fatality figures offered by the CDC:• Out of the 5,000 food-borne illness deaths each year in the United States, only 1,809 are "attributable to foodborne transmission" according to the CDC (http://www.cdc.gov/ncidod/EID/vol5no5/mead.htm#Table%203).• E.coli, which is often quoted in the big scare stories about food safety, only kills 78 people a year through food-borne transmission (52 plus 26, fro...

F-089 * minimally invasive oesophagectomy more expensive than open at north american hospital despite shorter length of stay :: Conclusions
The operating room costs associated with minimally invasive oesophagectomy are significantly higher than open transthoracic or transhiatal approaches. Unfortunately, a shorter hospital stay after MIO does not consistently offset higher surgical expenses, as the total hospital costs trend is higher in the MIO patients. In a strained health care economy, efforts to reduce costs associated with the minimally invasive approach should address the postoperative period as well as operating room expenses.

Do fluoride levels in cheap tea pose a health risk? :: Conclusion
This study suggests that people drinking economy brands of tea may be exposed to high levels of fluoride, which can cause dental and bone problems. The researchers calculate that people drinking 1 litre of cheap tea a day may be consuming more fluoride than the daily recommended amount, as advised by US experts. However, as the authors themselves say, in the US the "upper tolerable limit" of fluoride is 10mg of fluoride daily. The researchers' calculations are not based on this maximum limit – but on recommended daily intake.
In some parts of the world the natural fluoride levels in water are excessive and this is known to cause serious dental and bone problems.
In the UK, severe fluorosis is rare, although mild fluorosis, in which the teeth become stained, may occur in...
