The most comprehensive one-volume guide of its kind, this indispensable reference work presents information on teratogenic agents in a ready-reference format. The revised and expanded twelfth edition contains approximately three hundred new entries -- including one hundred newly listed agents and developmental genes that cause syndromes or congenital defects. Also included are overviews of recent literature on clinical and experimental teratology, including important Japanese literature not easily available to English-language researchers. As in previous editions, this volume emphasizes human data and covers pharmaceuticals, chemicals, environmental pollutants, food additives, household products, and viruses. A special effort has been made to obtain as much information as possible on drugs and other agents to which pregnant women should not be exposed. Substances are listed alphabetically and each entry briefly summarizes research procedures and results. In addition, a complete list of references is included for each agent.
From the archive: “Think of the kids you don’t have,” Mr. Levchin quoted them as saying. “Think of your unborn grandkids.”
It is best not to wear a denim miniskirt so short that when seated it practically disappears beneath the protuberance of one's pregnant belly, producing an image that is more gynecological than fashionable. Lauer: How far along are you? Spears: I don’t know. I think six to seven months. Spears: That driving incident, I did it with my dad. I’d sit on his lap and I drive. We’re country.

Rejuvenating the Sun and Avoiding Other Global Catastrophes |

And here I had dismissed Sunshine as pseudo-science. This book investigates the idea that the distant future evolution of our Sun might be controlled (literally, asteroengineered) so that it maintains its present-day energy output rather than becoming a highly luminous and bloated red giant star a process that, if allowed to develop, will destroy all life on Earth. The text outlines how asteroengineering might work in principle and it describes what the future solar system could look like. It also addresses the idea of asteroengineering as a galaxy-wide imperative, explaining why the Earth has never been visited by extraterrestrial travellers in the past.

Intern, by Sandeep Jauhar |

Intern is Sandeep Jauhar’s story of his days and nights in residency at a busy hospital in New York City, a trial that led him to question our every assumption about medical care today. Residency -- and especially the first year, called internship -- is legendary for its brutality. Working eighty hours or more per week, most new doctors spend their first year asking themselves why they wanted to be doctors in the first place. Jauhar’s internship was even more harrowing than most: he switched from physics to medicine in order to follow a more humane calling—only to find that medicine put patients’ concerns last. He struggled to find a place among squadrons of cocky residents and doctors. He challenged the practices of the internship in The New York Times, attracting the suspicions of the medical bureaucracy. Then, suddenly stricken, he became a patient himself—and came to see that today’s high-tech, high-pressure medicine can be a humane science after all. Now a thriving cardiologist, Jauhar has all the qualities you’d want in your own doctor: expertise, insight, a feel for the human factor, a sense of humor, and a keen awareness of the worries that we all have in common. His beautifully written memoir explains the inner workings of modern medicine with rare candor and insight.

Scientists image vivid ‘brainbows' |

By activating multiple fluorescent proteins in neurons, neuroscientists at Harvard University are imaging the brain and nervous system as never before, rendering these cells in a riotous spray of colors dubbed a “Brainbow.”
This is from a few months ago but apparently it hasn't been cited here. The Nature article, Transgenic strategies for combinatorial expression of fluorescent proteins in the nervous system, is available in the Google cache. The editor wrote: The 'Brainbow' technique can paint hundreds of individual neurons with distinctive hues, producing a detailed map of neuronal circuitry. This technology should not only boost mapping efforts in normal or diseased brains, but could also be applied to other complex cell populations, such as the immune system.

A sort of follow-up on Professors Could Take Performance-Enhancing Drugs for the Mind. When imagining the possible influences of efficient cognitive enhancers on society as a whole, there can be many positive effects. Such drugs may enable individuals to perform better and enjoy more achievements and success. However, cognitive enhancers may have a darker side. Fears have been raised of an overworked 24/7 society pushed to the limits of human endurance, or of direct and indirect coercion into taking such drugs. If other children at school or colleagues at work are taking cognitive-enhancing drugs, will you feel pressure to give them to your children or take them yourself? What if a perfectly safe and reliable cognitive enhancer existed, could society deny it to healthy individuals who may benefit from it?

Jonah Lehrer's smart, elegantly written little book expresses an appealing faith that art and science offer different but complementary views of the world. His main argument, that artists have often intuited essential truths about human nature that are later verified by scientific research, is hardly new. But he pursues this argument with freshness and enthusiasm in eight enjoyable case studies studded with arresting sentences that voice the 25-year-old author's delighted sense of discovery.

Proteins are the most diverse and versatile set of biological macromolecules, having crucial roles in all biological processes. Now that researchers have identified whole complements of proteins (proteomes) for many cell types, they are pushing the frontiers of protein science: from the regulation and function of single protein dynamics to the evolution and inhibition of protein–protein interactions.
