4:00 PM | Kurz notiert: Gleichzeitiger Schutz vor Alkoholsucht und –schäden?
Es wird ja schon sehr lange diskutiert und untersucht, ob die Aufnahme moderater Mengen an Alkohol, genauer: Ethanol nun leichte Gesundheitsvorteile birgt oder nicht; eine aktuelle Studie schränkt diese eventuellen Vorteile zudem auf Personen mit einer speziellen genetischen Disposition ein [1]. Unstrittig ist hingegen, daß chronischer Alkoholabusus sehr verbreitet und überaus schädlich ist, da er…

3:01 PM | Model systems may share adaptations for rapid development...
Model systems may share adaptations for rapid development that are not present in more slowly developing species. One form of embryonic adaptation for rapid development is prepatterning in the egg. Maternal loading of the egg removes the constraint on speed that would be imposed if the embryo had to synthesize all the necessary proteins, including ribosomes, de novo However, this strategy introduces other kinds of constraints: for example, it provides a wide scope for maternal regulation of […]

2:46 PM | Nobelist John Pople on using theories and models the right way
John Pople was a towering figure in theoretical and computational chemistry. He contributed to several aspects of the field, meticulously consolidated those aspects into rigorous computer algorithms for the masses and received a Nobel for his efforts. The Gaussianset of programs that he pioneered is now a mainstay of almost every lab in the world which does any kind of molecular calculation at the quantum level.On the website of Gaussian is a tribute to Pople from his former student (and […]

1:17 PM | What’s the Answer? (network analysis, plants)
This week’s question comes up on a pretty regular basis, but I always like to see what people are using for exploring the networks of their genes of interest. This was a new species, though, and I was curious to see if there was something particularly relevant to this plant. Biostars is a site for […]

12:03 PM | Not yet, on sustainability, it seems....
This post is triggered by the beginning of the biking season here.  Joy of joys!!  When the snow's gone and the temperature gets far enough above freezing for weaklings like me to venture out on my bike, I like to see what's changed along the many various paths that are here, since the previous autumn when I put my bike in the basement to wait out the long, icy winter.  My usual reaction is that an important message hasn't gotten through at all.We live in a land-grant university […]

11:49 AM | On Scientific Research Career Prospects
A lot of e-mails I get are from high-school students or their parents, asking about job prospects for zoology or palaeontology.
