I usually limit my book reviews to Goodreads or Shelfari but this one deserves much more attention. In Happy Accidents: Serendipity in Modern Medical Breakthroughs; When Scientists Find What They're NOT Looking for, Morton Meyers reviews examples of the unpredictability of scientific progress. This could just be a collection of interesting anecdotes - and some of the stories are truly fascinating. My favorite is probably the discovery of platinum compounds for the treatment of cancer.

Rogue prefers his steak medium-well. But when it comes to sniffing out a rare plant, this dog performs work that’s very well done, indeed.

The 4-year-old Belgian sheepdog is part of a Nature Conservancy collaborative project to test the efficacy of using dogs to sniff out the threatened Kincaid’s lupine . The plant is host to the endangered Fender’s blue butterfly, found only in Oregon’s Willamette Valley.

Five years ago, Edith had a problem: Her goldfish of 25 years, Mr. Fish, had dropsy, a disease characterized by a swollen or hollow abdomen and in most cases fatal. In her last attempt to save her pet, on a whim, Edith wrote a message on GoldfishConnection asking for help.

Rick G. Copeland, the specialist at the goldfish site, recommended some Medi-Gold pellets. Two years later, at age 27, Mr. Fish swam around his tank as if his close call with death never happened.

Mr. Fish may not have the 49 year-old record of the oldest goldfish ever, but he's working on it. In the meantime, Mr. Fish is competing with the millions of other pet goldfish around the world.

Was Hippasus pushed? If you are even mildly interested in the history of mathematics, it is likely that you will have heard something like the following story. The Pythagoreans (who were also into music in a big way) worshipped numbers, and believed them to be the basis of everything. If one were to do a modern caricature of this, it might go:

  Do you believe in Rock ’n’ Roll?
  Can mathematics save your soul?

By numbers, they meant whole numbers or positive integers. Whether this included ‘one’ is a moot point, because later Greek mathematicians regarded ‘one’ as the ‘generator of numbers’. One day, a man called Hippasus discovered that the square root of 2 was irrational. This went so much against the Pythagorean world view that they took him out to sea and threw him overboard. It didn’t stop there, though.

Conservation zones, or 'No-take areas' (NTAs), that were set up to protect fish in the late 1960s and early 1970s are in the wrong place to protect vulnerable coral reefs from the effects of global warming, an international team of scientists warned today.

Now the team, led jointly by Newcastle University and the Wildlife Conservation Society, say that urgent action is needed to prevent the collapse of this important marine ecosystem.

The research is the largest study of its kind to have been carried out, covering 66 sites across seven countries and spanning over a decade in the Indian Ocean.

Contrary to stereotypes about masculinity, men interviewed in a large international study reported that being seen as honorable, self-reliant and respected was more important to their idea of masculinity than being seen as attractive, sexually active or successful with women.

The study published in the Journal of Sexual Medicine included interviews with more than 27,000 randomly selected men from eight countries (Germany, U.S., U.K., Spain, Brazil, Mexico, Italy and France), with about 16 percent of the men reporting erectile problems.

Regardless of age or nationality, the men more frequently ranked good health, harmonious family life and good relationships with their wife or partner as more important to their quality of life than material, self-fulfilling or purely sexual concerns. There was no significant difference in rankings of masculinity and quality of life characteristics between men who experienced erectile dysfunction and those who did not.

Do babies says "mama" and "papa" because they recognize their parents or did those words become terms for parents because that's what babies first say?

The human brain may be hard-wired to recognize certain repetition patterns, according to a study in Proceedings of the National Academy of Sciences.

Using the latest optical brain imaging techniques, University of British Columbia post-doctoral fellow Judit Gervain and a team of researchers from Italy and Chile documented brain activities of 22 newborns (2-3 days old) when exposed to recordings of made-up words.

How do galaxies form? The most widely accepted answer to this fundamental question is the model of 'hierarchical formation', a step-wise process in which small galaxies merge to build larger ones. One can think of the galaxies forming in a similar way to how streams merge to form rivers, and how these rivers, in turn, merge to form an even larger river.

This theoretical model predicts that massive galaxies grow through many merging events in their lifetime. But when did their cosmological growth spurts finish? When did the most massive galaxies get most of their mass?

Hydrogen will be one of the most important fuels of the future, if it can be obtained by efficiently splitting water. Today the electrolysis of water is a very energy intensive process, making it both expensive and unsustainable if the electricity necessary to generate it comes from the burning of fossil fuels anyway.

Photolysis, the splitting of water by light, is a highly promising alternative. A team of Australian and American researchers has now developed a catalyst that effectively catalyzes one of the necessary half reactions, the photooxidation of water. As it reports in the journal Angewandte Chemie, the core of the catalyst is a manganese-containing complex modeled after those found in photosynthetic organisms.

A new study from researchers at the University of Pittsburgh and Carnegie Mellon University sheds light on why smokers' intentions to quit “cold turkey” often fizzle out within days or even hours.

If a smoker isn't yearning for a cigarette when he makes the decision to kick the habit-and most aren't-he isn't able to foresee how he will feel when he's in need of a nicotine buzz.

Published in the September issue of Psychological Science, a journal of the Association for Psychological Science, the study, “Exploring the Cold-to-Hot Empathy Gap in Smokers,” bolsters the theory that smokers not in a state of craving a cigarette will underestimate and underpredict the intensity of their future urge to smoke.
