Extraterrestrial Seed

Earlier this month, NASA announced the discovery of DNA components in a meteorite. On We Beasties, Heather Olins writes that “while claims of meteorites containing DNA components have been made before, they may very well have been terrestrial contamination. This seems to be different, because the meteorite also contains similar molecules that are never found…

Chemistry is nothing if not a double-edged sword. The complex interplay of atoms and molecules is the very foundation of life (and better living) but that complexity also means that a even a slight alteration of a safe substance’s chemical composition can make it into something exquisitely deadly. So please give Deborah Blum, chemistry enthusiast…

In the use of immunopharmacotherapy to treat drug abuse, antigenic molecules are hitched to molecules of the drug to stimulate a future immune response against the drug itself; as DrugMonkey reported this week, a recently published paper offers hopeful evidence that it could be a potentially effective treatment against cocaine addiction, though he cautioned, “It…

That was it, we’re back. After six inspiring days in Lindau, the Nobel Laureates Meeting 2009 has ended. Eight authors blogged about it on ScienceBlogs Germany, plus we had further blogging guests such as PZ Myers, Bora Zivkovic and Seema Singh. I did not make myself heard in the last two days. That was due…

Naked chemists!

Phew. The fourth day in Lindau is about to end and I think I speak for everybody when I say extreme humidity is not exactly our favourite aggregate state concerning the weather in this town. Nevertheless we’ve had another great day at the Nobel Laureates Meeting and would like to share thus with you, fellow…

Ask an informed layman what he or she thinks is the greatest science-based industrial discovery or invention of all time and the person will likely name the computer, the transistor, the telephone, the incandescent light or perhaps even the blast furnace. But key as all these inventions were to humanity’s progress, there is perhaps one…

When the chemist Wilhelm Ostwald received the Nobel prize for his research on catalysis in 1909 he probably didn’t expect that his field of work would still be one of the most important topics in modern chemistry one hundred years later. Nevertheless all three Nobel Prizes in chemistry in the last years were given to…

Annually focusing on a different discipline, the Nobel Laureates meet in Lindau (Southern Germany). This year’s meeting is going to be about chemistry and we, the editors of ScienceBlogs.de will be covering all events along with seven blogging scientists. Although there will of course be lots of articles in German, we also launched an English…

Hello, and welcome to the Sweet Sixteen round of the Science Spring Showdown—ScienceBlogs’ answer to March Madness. (Feeling confused? Catch yourself up on what this is all about, here). The phrase “Mad as a March Hatter” might be apposite. But be that as it may, Page 3.14 is nothing short of delighted to host the…

Since moving to New York, I’ve been having trouble breathing. Is city air pollution to blame? Source: European Space Agency. The above image shows atmospheric nitrogen dioxide concentrations worldwide. Nitrogen dioxide (NO2) is a mainly man-made gas, produced by the usual suspects: power plants, transportation, industry, and biomass burning. Lightning in the air, and microbes…
