What matters are the ideas, not the brains in which they alight. Posted without fear of thievery on the Internet beginning in 2002, his proof, consisting of three dense papers, gives glimpses of a world of pure thought that few will ever know. Who needs prizes when you are free to wander across a plane so lofty that a soda straw and a teacup blur into the same topological abstraction, and there is nothing that a million dollars can buy?

A Whole New Mind: Why Right-Brainers Will Rule the Future, by Daniel Pink |

Just as information workers surpassed physical laborers in economic importance, Pink claims, the workplace terrain is changing yet again, and power will inevitably shift to people who possess strong right brain qualities. His advocacy of "R-directed thinking" begins with a bit of neuroscience tourism to a brain lab that will be extremely familiar to those who read Steven Johnson's Mind Wide Open last year, but while Johnson was fascinated by the brain's internal processes, Pink is more concerned with how certain skill sets can be harnessed effectively in the dawning "Conceptual Age." The second half of the book details the six "senses" Pink identifies as crucial to success in the new economy-design, story, symphony, empathy, play and meaning-while "portfolio" sections offer practical (and sometimes whimsical) advice on how to cultivate these skills within oneself. Thought-provoking moments abound-from the results of an intensive drawing workshop to the claim that "bad design" created the chaos of the 2000 presidential election-but the basic premise may still strike some as unproven. Furthermore, the warning that people who don't nurture their right brains "may miss out, or worse, suffer" in the economy of tomorrow comes off as alarmist. But since Pink's last big idea (Free Agent Nation) has become a cornerstone of employee-management relations, expect just as much buzz around his latest theory.

"It was a great mission and a great success and now it's over," said mission manager Gerhard Schwehm. During its months in orbit around the moon, the spacecraft scanned the lunar surface from orbit and took high-resolution pictures. But its primary mission was testing a new, efficient, ion propulsion system that officials hope to use on future interplanetary missions, including the BepiColombo mission to Mercury slated for 2013.

A small biotech company says it has found a way to produce human embryonic stem cells without destroying an embryo. That the prospect does not satisfy many religious conservatives who have opposed stem cell research demonstrates once again why the government should avoid making decisions on theological grounds.
Remember what happened in Ireland? This illustrates the great lengths to which scientists must go these days to shape stem cell research to fit the dictates of religious conservatives who have imposed their own view of morality on the scientific enterprise.

The Elements of Murder: A History of Poison |

From Publishers Weekly: Starred Review. Emsley (Vanity, Vitality, and Virility: The Science Behind the Products You Love to Buy) hits a bull's eye in this fascinating, wonderfully readable forensic history of five deadly chemicals (mercury, arsenic, antimony, lead and thallium) and their starring role in that most intoxicating drama of pure evil: murder. A deeply knowledgeable chemist (he's science writer in residence at Cambridge University) with a gift for making accessible the dry and bewilderingly arcane, Emsley's at his best in case studies of infamous poisoners and their victims. During the reign of James I of England, for instance, the poet Thomas Overbury, having fallen out of royal favor, was administered three fatal doses of mercury, only to survive. For his stubbornness he was administered a fourth dose—by enema—and finally succumbed. Mary Bateman, the "Yorkshire Witch," was equally unlucky. Convicted in 1809 of poisoning a client, Mary was hanged and her corpse skinned so pieces could be sold as charms. Not all the incidents are in the past: Emsley also discusses contemporary environmental poisoning from mercury and Saddam Hussein's use of thallium sulfate on his enemies. Fanatical devotees of the macabre might thumb past sections devoted to less sensational history. But the general reader will not be disappointed: each of these deadly toxins was at one time or another promoted for its unique health or beauty benefits.

Why editors must dare to be dumb |

In science, feeling confused is essential to progress. An unwillingness to feel lost, in fact, can stop creativity dead in its tracks. A mathematician once told me he thought this was the reason young mathematicians make the big discoveries. Math can be hard, he said, even for the biggest brains around. Mathematicians may spend hours just trying to figure out a line of equations. All the while, they feel dumb and inadequate. Then one day, these young mathematicians become established, become professors, acquire secretaries and offices. They don’t want to feel stupid anymore. And they stop doing great work.

Biotechnology Unzipped: Promises and Realities, Revised Second Edition |

Skilled science popularizer Eric Grace helps readers understand what biotechnology is and what implications it holds for all of us. Following on the heels of the success of the first edition, this thoroughly updated version offers an in-depth and accessible review of the basics of biotechnology. Accomplished science communicator Eric Grace focuses on the ethical implications involved, the wide range of public opinions both at home and abroad, the role of the media in communicating a complicated science topic, and the formidable problems associated with patenting life itself. With an emphasis on medicine, agriculture, and the environment, Grace explores the promises and realities of biotechnology. He deals frankly with the fact that biotechnology is first and foremost a commercial activity, often driven by big business and directed by the bottom line. And as biotechnology is used more frequently in medical diagnosis and treatment, we are witness to significant setbacks and reversals, dimming hopes that were prevalent when the first edition was released. But we are also witness to the burgeoning use of the technology in forensic science where DNA analysis has become commonplace in solving crimes. Likewise, DNA analysis has been a boon to studies of human history and evolution, revealing ancient details originally thought lost to us. At the same time, new uses for genetically altered bacteria are being discovered that help us clean up the environment by breaking down or sequestering toxic chemicals. While the public remains concerned about biotechnology, there is increasing awareness of the potential benefits. This updated edition of Biotechnology Unzipped helps put the many issues in perspective and provides answers to the most important questions.

Clusters: A bridge between disciplines |
|

Topic: Science |

Cluster, defined as a group or bunch in Webster's dictionary, has different meanings depending on the given discipline. In medicine, for example, a cluster can refer to a severe headache that can occur several times in a day, whereas, in astronomy, clusters are usually associated with stars and galaxies. Clusters also are associated with bombs, music, and computers. However, to physicists and chemists, the word cluster has come to mean a group of atoms or molecules formed by interactions ranging from very weak van der Waals contacts to strong ionic bonds. Although reference to the formation of aggregates and related nucleation phenomena can be found in literature dating from the 1930s and earlier, studies of clusters in mass spectrometer ion sources and later in molecular beams (1) began to emerge in the 1950s and developed rapidly as a subject of considerable interest in the 1970s and 1980s. The advent of the laser vaporization technique (2) enabled researchers to produce clusters of virtually any element in the periodic table and spawned wide-ranging interest in the studies of clusters of various compositions, beyond systems of volatile materials, which had been the focus in the beginning. For this community, in the past 30 years clusters have come to symbolize a new embryonic form of matter that is intermediate between atoms and their bulk counterpart. Clusters bridge phases as well as disciplines.
