Chemists reported development of what they termed the first economical, eco-friendly process to convert algae oil into biodiesel fuel — a discovery they predict could one day lead to U.S. independence from petroleum as a fuel.

One of the problems with current methods for producing biodiesel from algae oil is the processing cost, and the New York researchers say their innovative process is at least 40 percent cheaper than that of others now being used. Supply will not be a problem: There is a limitless amount of algae growing in oceans, lakes, and rivers, throughout the world.

Another benefit from the "continuously flowing fixed-bed" method to create algae biodiesel, they add, is that there is no wastewater produced to cause pollution. 

Re-engineering a protein that helps prevent tumours spreading and growing has created a potentially powerful therapy for people with many different types of cancer. In a study published in the first issue of EMBO Molecular Medicine, Canadian researchers modified the tumour inhibiting protein, von Hippel-Lindau (VHL), and demonstrated that it could suppress tumour growth in mice.

New data from Ugandan scientists and investigators at Johns Hopkins University find that adult male circumcision decreased rates of the two most common sexually transmitted infections – herpes and the human papillomavirus (HPV), the virus that causes cervical cancer and genital warts – according to a report issued in the New England Journal of Medicine March 26, 2009.

In an accompanying editorial, "Prevention of Viral Sexually Transmitted Infections – Foreskin at the Forefront," two local University of Washington researchers say these new findings provide compelling new evidence on circumcision's effect on decreasing currently incurable viral sexually transmitted infections.

Reports by scientists of meteorites striking Earth in the past have resembled police reports of so many muggings — the offenders came out of nowhere and then disappeared into the crowd, making it difficult to get more than very basic facts.

Now an international research team has been able to identify an asteroid in space before it entered Earth's atmosphere, enabling computers to determine its area of origin in the solar system as well as predict the arrival time and location on Earth of its shattered surviving parts.

A new study appearing in Clinical Cardiology examines the average fitness level of the morbidly obese (body mass indexes between 40.0 and 49.9). The findings show that the tested population was sedentary for more than 99 percent of the day and, on average, walked less than 2,500 steps per day – far below healthy living guidelines of 10,000 steps per day. The results provide important links between obesity, poor fitness and cardiovascular disease.

The study used a precise body sensor to continually measure physical activity, caloric expenditure and movement minute-by-minute over a 72-hour period within their home environments. Following collection of the data, structured cardiorespiratory fitness testing was performed on each subject. 

Norma Wooley checked into Loyola University Hospital on a recent Monday morning for brain surgery to repair a life-threatening aneurism (also: aneurysm).  She went home on Tuesday, cured of the slurred speech, drooping face and worst headache of her life.

Wooley had a cerebral aneurism, a weak spot in a blood vessel that balloons out and fills with blood. About six million Americans -- 1 in 50 people -- have brain aneurisms that could rupture. Each year, aneurisms burst in about 25,000 people, and most die or suffer permanent disabilities, according to the Brain Aneurysm Foundation.

You may soon be able to say goodbye to batteries for your Blackberry or cell phone.  Instead, they will get power from just a wave of your hand.

In research presented at the ACS meeting in Salt Lake City, scientists describe technology that converts mechanical energy from body movements or even the flow of blood in the body into electric energy that can be used to power a broad range of electronic devices without using batteries.

"From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent."

Thus spoke Sir Winston Churchill, in the company of President Harry S. Truman, on March 5, 1946, at Westminster College, Fulton, Missouri.

But this Iron Curtain was not a single boundary, but two fences (mostly) separated by a furlong or so (5 furlongs = 1 kilometre) with a no-man’s-land in between.
