12:36 PM | Friday Cephalopod: Your mother sacrificed so much for you…
Have you called her lately? Look at this mother octopus, clinging to a deep-sea cliff, hanging over the abyss, guarding her clutch of eggs. She stayed there, never leaving, for four years. The MBARI submersible would regularly visit the spot and check on her, and there she was, getting weaker and weaker, but still defending…

4:00 PM | Polio ausrotten – so nahe dran!
Poliomyelitis, auch bekannt als Kinderlähmung, ist eine schlimme, durch Viren ausgelöste Krankheit, die v.a. unter schlechten hygienischen Bedingungen durch fäkal-orale Schmierinfektionen übertragen wird. In Deutschland kommt sie seit 1992 praktisch überhaupt nicht mehr vor, dafür aber in anderen Weltregionen, z.B. einigen afrikanischen Ländern, Indien, Pakistan und Afghanistan, obwohl das vermeidbar wäre und trotz der enormen…

10:36 PM | Creationist ‘audits’ science museum
Imagine you are 10 years old and your crazy aunt is taking you out for a treat. A crazy aunt can be fun. Problem is this aunt is also a creationist and she is taking you to the local natural history museum. … Continue reading →

9:37 PM | When you think about spirits, do you see ghosts?
Humans are finely honed for spotting intentional agents in our environment. Meaning that if you hear a rustling, or see a branch move, you’re instantly on the alert in case it is another person (this effect is has a name: ‘hyperactive agency detection’). You can see why evolution would have favoured that. Better safe than [Read More...]

The Heartland Institute has produced a new propaganda poster on climate change. Here it is: And this is what they say about it: This poster presents clear and undeniable evidence that the debate is not over. Looking out from this poster … Continue reading →

3:30 PM | Homöopathie taugt nicht mal als Ausrede
Daß es sich bei Homöopathie um bestenfalls nutzlose, schlimmstenfalls gefährliche Esoterik handelt, wurde u.v.a. auch hier immer wieder diskutiert und vorgeführt und darf getrost als Fakt betrachtet werden. In der Forensik hingegen hat man es recht selten mit Homöopathie zu tun: gegen den Tod hat die Homöopathie noch kein Mittel gefunden, Vergiftungen mit reinem Wasser…

9:02 PM | Water fluoridation and dental fluorosis – debunking some myths
Dental fluorosis is really the only “negative” side effect of community water fluoridation (CWF). It occurs in non-fluoridated as well as fluoridated areas but is often a little more common in the fluoridated areas. However, there is a lot of … Continue reading →

1:50 PM | The two faces of JE Brandenburg
Brandenburg is a physicist who submitted a paper to the 42nd Lunar and Planetary Science Conference a few years ago. It’s way outside my area of expertise, but it postulated an interesting scenario from the ratios of rare isotopes in the atmosphere of Mars: that there was evidence of a natural nuclear reactor, like Oklo…

Bei Compound Interest habe ich eine Liste von Tips gefunden, die helfen können, schlecht gemachte oder berichtete Wissenschaft und Forschung zu erkennen. Sie hat mir so gut gefallen, daß ich sie gestohlen und übersetzt habe und nun hier präsentiere. Die Liste ist nicht erschöpfend und nicht jeder erfüllte Punkt macht eine Studie oder einen Artikel…

8:43 PM | Religious and paranormal believers are high in empathy – but confused about how the world works
There’s a strand of thought that says that belief in the supernatural is founded upon a misunderstanding of how the world works (see: You either believe in it all, or you don’t). On the other hand, there’s another perspective that says the cognitive problem is with the atheists. Belief in gods, according to this school [Read More...]

Se trataba de una fractura doble de tobillo (confieso ser aficionado a los videos morbosos; me encanta ver cómo se exprimen barros y espinillas, se extraen tapones de […]

2:19 PM | Every university is broken
But the University of Hawaii at Mānoa looks to be more broken than others. Christie Wilcox writes about the budget cuts there: the place is being gouged to the bone — the College of Natural Sciences has a cohort of graduate students to whom they are failing to live up to their responsibilities (the university…

12:40 PM | A specular conundrum
Every year in my intro biology course, I try to do one discussion of bioethics. One lecture is not much, but this is a course where we try to introduce students to the history and philosophy of science, and I think it’s an important issue, so I try to squeeze in a little bit. So…

Just consult the chart. Be sure to click on the image to see it at a better resolution! This is from a paper that looked at the molecular phylogenies, and worked out estimated branch times. I like it. I want it on my wall. Insects are the most speciose group of animals, but the phylogenetic…

Oh, great. Orac just has to tell me that the University of Minnesota is going to host an anti-vaccine conference on 24 January. First, let me say this, though: they get to do that. Presumably they’ve rented out (or possibly obtained student or faculty sponsorship) Cowles Auditorium at the Humphrey School of Public Affairs, and…

We hebbeneen overheid die niet in staat is artikel 1 van de Grondwet af te dwingen, die er ook niet in slaagt de schijn van neutraliteit hoog te houden doordat men het gevaar vooral lokaliseert bij zwarte burgers (maar niet de zwart geschminkte burgers) en de steen des aantoots juist gebruikt om voor veiligheid van witte burgers te zorgen. En geen enkele politicus die daar ook maar één kritisch woord over uitbrengt.

10:28 PM | Hard times, tough gods
Almost all cultures have some kind of supernatural beliefs. But it may surprise you to know that belief in moralising supernatural beings, who care about whether mortals do good or bad, are far from universal. That’s fascinating, and it begs the question: “why?”. Why do some cultures bother to believe spirits who watch over us [Read More...]
