It seems pregnancy may confer some protection against bladder cancer - in mice. Female mice that had never become pregnant had approximately 15 times as much cancer in their bladders as their counterparts that had become pregnant, according to new findings by investigators at the University of Rochester Medical Center.

The researchers led by Jay Reeder, Ph.D., are focusing on a fact that has puzzled doctors and scientists for decades: Why does bladder cancer, the fifth most common malignancy in the nation, affect about three times as many men as women?

Scientists long blamed men's historically higher rates of smoking and greater exposure to dangers in the workplace, but the gap has persisted even as women swelled the workforce and took up smoking in greater numbers.

Researchers at Bonn University and the ETH Zürich have discovered that oregano, with its active ingredient beta-caryophyllin (E-BCP, docks on specific receptor structures in the cell membrane - the so-called cannabinoid-CB2 receptors, and produces a change in cell behavior: for example, it will inhibit the cell´s production of phlogogenic signal substances.

E-BCP is a typical ingredient of many spices and food plants. Hence it is also found in plants such as basil, rosemary, cinnamon, and black pepper. Every day, we consume up to 200 milligrams of this annular molecule.

The researchers administered E-BCP to mice with inflamed paws and in seven out of ten cases there was a subsequent improvement in the symptoms. E-BCP might possibly be of use against disorders such as osteoporosis and arteriosclerosis.

People who are bicultural and speak two languages may actually shift their personalities when they switch from one language to another, according to new research in the Journal of Consumer Research.

"Language can be a cue that activates different culture-specific frames," write David Luna (Baruch College), Torsten Ringberg, and Laura A. Peracchio (University of Wisconsin-Milwaukee).

The authors studied groups of Hispanic women, all of whom were bilingual, but with varying degrees of cultural identification. They found significant levels of "frame-shifting" (changes in self perception) in bicultural participants—those who participate in both Latino and Anglo culture. While frame-shifting has been studied before, the new research found that biculturals switched frames more quickly and easily than bilingual monoculturals.

New exquisitely preserved fossils from Latvia cast light on a key event in our own evolutionary history, when our ancestors left the water and ventured onto land. Swedish researchers Per Ahlberg and Henning Blom from Uppsala University have reconstructed parts of the animal and explain the transformation in the new issue of Nature.

It has long been known that the first backboned land animals or "tetrapods" - the ancestors of amphibians, reptiles, birds and mammals, including ourselves - evolved from a group of fishes about 370 million years ago during the Devonian period. However, even though scientists had discovered fossils of tetrapod-like fishes and fish-like tetrapods from this period, these were still rather different from each other and did not give a complete picture of the intermediate steps in the transition.

A new analysis of Martian soil data led by University of California, Berkeley, geoscientists suggests that there was once enough water in the planet's atmosphere for a light drizzle or dew to hit the ground, leaving tell-tale signs of its interaction with the planet's surface.

The study's conclusion breaks from the more dominant view that the liquid water that once existed during the red planet's infancy came mainly in the form of upwelling groundwater rather than rain.

To come up with their conclusions, the UC Berkeley-led researchers used published measurements of soil from Mars that were taken by various NASA missions: Viking 1, Viking 2, Pathfinder, Spirit and Opportunity. These five missions provided information on soil from widely distant sites surveyed between 1976 and 2006.

A classified assessment by the National Intelligence Council (NIC) says climate change could threaten U.S. security in the next 20 years by causing political instability, mass movements of refugees, terrorism, or wars over water. The House Intelligence Committee will get a briefing today on the main findings and the full report will be released Monday, June 30th.

It's the perfect storm of buzzwords. This might be check and mate for environmental activists. Relating global warming to terrorism is a masterstroke of logical and cultural hand trickery but what can Big Oil do, deny there is terrorism? No one is more impacted by sea level rise than the Dutch so look for that military build-up in Holland over the next few years. The Belgians have it coming.

The assessment itself is confidential, because the other 6 billion of us won't be impacted by global warming or world wars over water, but thankfully some analyses used as raw material will be open, including a series of studies done by Columbia University's Center for International Earth Science Information Network (CIESIN). On commission from NIC, CIESIN ranked countries by looking at three climate risks: sea-level rise, increased water scarcity, and an aggregate measure of vulnerability based on projected temperature change, compared with nations' ability to adapt.

The sexual and feminist revolutions were supposed to free women to enjoy casual sex just as men always had but according to Professor Anne Campbell from Durham University in the UK (1), the negative feelings reported by women after one-night stands suggest that they are not well adapted to fleeting sexual encounters.

Men are more likely to reproduce and therefore to benefit from numerous short-term partners. For women, however, quality seems to be more important than quantity. Also for women, finding partners of high genetic quality is a stronger motivator than sheer number, and it is commonly believed that women are more willing to have casual sex when there is a chance of forming a long-term relationship.

This University of Copenhagen press release says that they would like to be first to create a quantum computer. They have made no more progress than anyone else, really, but want us all to know that they are thinking about it.

We liked it so much we are just printing it as is:

Bassinet use in 2006 was nearly double what it was in 1992, and even though more than 45% of infants between the ages of 0-2 months use them, little is known about bassinet safety.

The Consumer Product Safety Commission (CPSC) has guidelines regarding bassinet construction but there are no government safety standards for bassinets. In 2005, the American Academy of Pediatrics (AAP) revised its recommendations for a safe infant sleep environment, suggesting a separate but nearby sleeping arrangement (i.e. roomsharing without bedsharing).

Two studies in The Journal of Pediatrics evaluate the frequency of bedsharing and the potential risk factors of bassinet use.

The proliferation of voluntary carbon offset programs seems like a great way for individuals to help fight climate change. But do carbon offset programs really work? That's the question for Bill Stanley, Science Lead for Carbon Strategies, Climate Change Team at The Nature Conservancy.

Lawrence Hamilton, of Charlotte, VT, asks:

"Are carbon offset programs and forest protection efforts providing real solutions for reducing global carbon emissions? And how do these programs help reduce pollution from mercury, arsenic and other "baddies" that often accompany carbon emissions?"

Bill Stanley, Science Lead for Carbon Strategies, Climate Change Team, replies:
