I got some questions from a writer named Captain Carrot who deduced that, because I write this column for peanuts, I must also be available for free science consultation and/or general life and relationship advice.

Here is a sample:

I am 27. Should I try to stop smoking, or will I regret it later in life?

Most of you know me well enough by now to realize that, unless you provide proof you are a supermodel, I am unlikely to even bother learning to spell your name.

Amit Kagian, an M.Sc. graduate from the TAU School of Computer Sciences, has successfully “taught” a computer how to interpret attractiveness in women.

The notion that beauty can be boiled down to binary data and interpreted by a mathematical model is nothing new. More than 2,000 years ago the Greek mystic, philosopher and mathematician Pythagoras observed the connection between math, geometry and beauty. He reasoned that features of physical objects corresponding to the “golden ratio” were considered most attractive.

But there’s a more serious dimension to this issue that reaches beyond mere vanity. The discovery is a step towards developing artificial intelligence in computers. Other applications for the software could be in plastic and reconstructive surgery and computer visualization programs such as face recognition technologies.

Selenium is a trace element used in proteins, in the form of the twenty-first naturally occurring amino acid (selenocysteine).

Selenium supplementation, for example in mineral tablets, might not be that beneficial for the majority of people according to researchers writing in Genome Biology.

Although this trace element is essential in the diet of humans, it seems that we have lost some of the need for selenium, which occurs in proteins and is transported in blood plasma, when our evolutionary ancestors left the oceans and evolved into mammals.

Unless a researcher owns stock in a company whose drug is being tested, telling potential research volunteers about an investigator’s financial interests is unlikely to affect their willingness to volunteer, a new study shows. But many research volunteers put less trust in clinical trial leaders with financial conflicts.

For the study, Jeremy Sugarman, M.D., M.P.H., M.A., professor at the Johns Hopkins Berman Institute of Bioethics and The Johns Hopkins School of Medicine and his colleagues at Duke University School of Medicine and Wake Forest Schools of Medicine and Law recruited 3,623 adults with asthma or diabetes from a national database of individuals who are willing to participate in internet-based research. Overall, the recruits, almost all white, were well educated and had middle to high income levels. They were located in all regions of the United States.

Most of the respondents indicated that the financial disclosure was less important to their decision about participating than such factors as potential risks and benefits, and the purpose of the research.

DUBAI, United Arab Emirates, April 3 /PRNewswire/ --

The 2008 World Summit of Innovation and Entrepreneurship (WSIE) -- the most inspiring gathering of its kind in Dubai -- concluded this afternoon, calling for improving the role of innovation as a catalyst for peace and development to improve the quality of lives for billions of people worldwide.

The three-day summit, organized under the patronage of His Highness Sheikh Hamdan Bin Mohammed Bin Rashid Al Maktoum, Crown Prince of Dubai, brought together over 800 delegates from all walks of life.

Dog owners, who have noticed that their four-legged friend seem equally delighted to see them after five minutes away as five hours, may wonder if animals can tell when time passes.

Newly published research from The University of Western Ontario in London, Canada may bring us closer to answering that very question.

William Roberts and his colleagues in Western’s Psychology Department found that rats are able to keep track of how much time has passed since they discovered a piece of cheese, be it a little or a lot, but they don’t actually form memories of when the discovery occurred. That is, the rats can’t place the memories in time.

CHICAGO, April 3 /PRNewswire/ --

The Certification Authority/Browser Forum (CAB Forum), the author of the guidelines for issuing Extended Validation (EV) SSL certificates, is pleased to announce that approximately 5,000 EV SSL certificates have been deployed by businesses and organizations worldwide(1) since the introduction of the guidelines last June.

Extended Validation SSL certificates were introduced last year to help businesses and organizations conducting e-commerce, e-banking or e-government to reliably assert their identities to end-users and consumers. EV SSL certificates are issued to entities that complete a rigorous validation process that includes the following criteria:

A team of researchers led by Danish professor Eske Willerslev shows that the ancestors of the North American Indians who came from Asia were the first people in America, and that they were of neither European nor African descent. It also shows that immigration to North America took place approximately 1,000 years earlier than assumed. These findings call for a revision of our understanding of the early immigration route to the American continent.

Willerslev, of the University of Copenhagen, and colleagues recently conducted DNA tests on samples of fossilized human feces found in deep caves in the Oregon desert and came to a conclusion sure to cause debate - the oldest of the droppings have been carbon-dated to be approximately 14,340 years old. Willerslev’s feces samples clearly contain two main genetic types of Asian origin that are unique to present-day North American Indians.

There are many interactions between the Sun and the Earth but one of the most dynamic events is a ‘substorm’ - an explosive reshaping of the Earth’s outer magnetic field.

To better understand substorms, scientists in Europe and North America are studying them from space using the Time History of Events and Macroscale Interactions during Substorms (THEMIS) satellites launched by NASA in 2007 and from the ground using a network of all-sky cameras.

University of Lancaster solar-terrestrial scientist Dr Emma Woodfield gave a talk at the Royal Astronomical Society National Astronomy Meeting in Belfast and presented the first few months of results from the Rainbow cameras newly installed in southern Iceland that complement this network.
