Here's a myth many men are happy has been debunked - contrary to popular thinking about the need for hours of sexual activity, a survey of U.S. and Canadian sex therapists says satisfactory sexual intercourse for couples lasts from 3 to 13 minutes.

Penn State Erie researchers Eric Corty and Jenay Guardiani conducted a survey of 50 full members of the Society for Sex Therapy and Research, which include psychologists, physicians, social workers, marriage/family therapists and nurses who have collectively seen thousands of patients over several decades.

Thirty-four, or 68 percent, of the group responded and rated a range of time amounts for sexual intercourse, from penetration of the vagina by the penis until ejaculation, that they considered adequate, desirable, too short and too long.

CALGARY, Canada, March 31 /PRNewswire/ -- First Calgary Petroleums Ltd.'s ("FCP", "the Company", "First Calgary") management team and chairman of the Board, Gar Emerson, are currently on a three-country tour meeting with shareholders to discuss the progress made in bringing the company into first production in 2010, its strategic plans for growth, and highlighting the strength and expertise of the management team, led by President and CEO Mr. Richard Anderson.

First Calgary has also embarked on an advertising campaign designed to help communicate this message. The advertisements appeared on Saturday, March 29 and today, Monday, March 31, in the Vancouver Sun, Calgary Herald, Toronto Star, National Post and Globe and Mail.

Common sense says that we are happier when we get more money to spend on ourselves. At least, that’s what passes for commonsense in modern capitalistic societies, from the United States to China.  Indeed, when Elizabeth Dunn and colleagues at the University of British Columbia and at Harvard Business School asked a bunch of their students (the usual subjects in social science studies), that’s exactly what they found: students thought they would be happier getting $20 than $5, and that they would be happier spending the money on themselves than on others.

Turns out, the students were spectacularly wrong.

Research over the past several years has steadily contradicted the capitalistic assumption about human nature. For instance, it is well known that there is only a weak correlation between income level and self-reported happiness across the globe, with the relationship plateauing (meaning that additional money does not increase happiness) at surprisingly low levels of income. And yet, people keep playing the lottery, or its white collar equivalent, the stock market. Why?

- Data Expands Body of Evidence in High Risk Population Using IVUS, a Unique Marker for Coronary Atherosclerosis

New data from a clinical trial using intravascular ultrasound (IVUS) technology found that in patients living with type 2 diabetes, ACTOS(R) (pioglitazone HCl) reduced the atherosclerotic burden in the coronary arteries compared to the sulphonylurea glimepiride, and prevented progression compared to baseline.

Less than three months after forecasters announced the beginning of a new solar cycle (cycle 24), that has been changed. Solar Cycle 23 is still kicking.

Last week, three sunspots appeared and their magnetic polarity says they are all old cycle spots. ESA Solar and Heliospheric Observatory (SOHO) Project Scientist Bernhard Fleck says, “If cycle 24 had already begun, the magnetic polarity of the spots would be reversed.”

Two solar cycles? At the same time?

It sounds strange but it is normal. Around the time of solar minimum - which is now - old-cycle spots and new-cycle spots frequently intermingle. Eventually Cycle 23 will fade to zero, giving way in full to Solar Cycle 24, but not yet.

Plants, crops and trees naturally absorb atmospheric carbon dioxide (CO2) during photosynthesis and then pump surplus carbon through their roots into the earth around them. In most soils, this carbon can escape back to the atmosphere or enters groundwater.

Knowing this, a team from Newcastle University aims to design soils that can remove carbon from the atmosphere, permanently and cost-effectively using soils containing calcium-bearing silicates.

Calcium silicates are minerals that occur naturally in many different rocks and also in artificial materials such as concrete.

- ASCD Middle East is first organization of its kind to provide educators in the region with tailored professional development and capacity building

The Association for Supervision and Curriculum Development (ASCD) announced the formation of ASCD Middle East. Sharing ASCD's mission and vision, ASCD Middle East will provide professional development and capacity building to the region's educators -- school administrators, officers of regional ministries of education, university professors, and classroom teachers, among others -- and will ensure that ASCD resources and programs are accessible and aligned with the needs of local educators.

Astronomers have spied a faraway star system that is so unusual, it was one of a kind - and then its discovery helped them pinpoint a second one much closer to home.

They discovered the first star system 13 million light years away, tucked inside Holmberg IX, a small galaxy that is orbiting the larger galaxy M81. They studied it between January and October 2007 with the Large Binocular Telescope (LBT) on Mt. Graham in Arizona.

The star system is unusual, because it’s what the astronomers have called a “yellow supergiant eclipsing binary” -- it contains two very bright, massive yellow stars that are very closely orbiting each other. In fact, the stars are so close together that a large amount of stellar material is shared between them, so that the shape of the system resembles a peanut.

UC Irvine scientists have discovered a cluster of galaxies in a very early stage of formation that is 11.4 billion light years from Earth – the farthest of its kind ever to be detected. These galaxies are so distant that the universe was in its infancy when their light was emitted.

The galaxy proto-cluster, named LBG-2377, is giving scientists an unprecedented look at galaxy formation and how the universe has evolved. Before this discovery, the farthest known event like this was approximately 9 billion light years away.

“When you observe objects this far away, you are actually seeing the universe as it was a very long time ago,” said Jeff Cooke, a McCue Postdoctoral Fellow in physics and astronomy at UCI and lead author of this study. “It is as if a timeline is just sitting out there in front of you. These galaxies represent what the universe looked like well before the Earth existed.”

The Netherlands Organization for Scientific Research has a couple of interesting things in the works, the first being next generation media storage. Dutch researcher Alexander le Fèbre has demonstrated that a field-emission current signal can be used to arrange the position of thousands of nanometre-sharp needles. These probes can be applied to write and read in new storage media with an extremely high density, using bits on a nanometre scale.

The development of the hard disk is reaching its technical limits because the entire disk is served by just a single head so the capacity of the disk and the reading and writing speed cannot expand much more in the future. Research into a memory based on probes from the University of Twente’s MESA+ research institute means able to control the position of each separate probe - essential for realizing a system with extremely high densities.
