Psycasm - Are Men Peacocks and Women Penguins?

by Rift in Psycasm

Silly analogies, I know. But it kind of gets the point across. A paper by Griskevicius et al (2006) suggests that, when individuals in a same-sex group are presented with the option of conforming or non-conforming when a sexy other is around, men and women behave differently.Let me explain, and more importantly, let me pose a question.Griskevicius et al (2006) conducted two studies. The first aske; (read more)

Cardiology: Murmurs!

by Science Exploiter in Science Exploits

The stethoscope has practically become the icon of healthcare.  To wear a stethoscope suggests that a person has some sort of clinical knowledge.  After all, why else would a person have a stethoscope on their person if they did not actually know how to use it?  A stethoscope amplifies sound to make very subtle noises audible to the human ear.  Thus the sounds of the hearts valves closing, the movement of air into and out of the lungs, the bowels doing their thing, and so on ........

Clinical research and the popular press: hefty tots in pills peril!

by Medical Media Watch in Medical Media Watch

So, continuing down the list of the 2005 British Medical Journal (BMJ) papers that generated the most interest among clinicians (this is part 2 of my analysis, for part 1 go here) I come to paper number 4, where vitamins rear their peppy heads. Lorna had a run-in with some vitamin B in her results: [...]... Read more »

Periodic impact

by Emma in we are all in the gutter

Engaging the public in science is something lots of us are passionate about but how do you measure its impact? This might seem like an unimportant question, but it’s something that funding agencies are increasingly interested in, as they understandably want to check their money isn’t being wasted. It’s also a question addressed by the [...]... Read more »

Setting the Record Straight on Meiosis

by Sanford- Burnham in Beaker

In 2006, a landmark Science paper set a new dogma for reproductive/developmental biology: retinoic acid in the ovaries triggers meiosis in utero, while an enzyme in the testes called Cyp26b1 keeps retinoic acid at bay and prevents meiosis from occurring until after birth. Just one problem – that paradigm is wrong. A recent Nature Communications paper sets the record straight.

The Flavors of SNPs

In Blink, Malcolm Gladwell discusses how experts do expert things. Essentially they develop granular languages to describe the characteristics of items, or experiences. Food tasters, for example, use a large and rich vocabulary with scores to...

How to Distract a Stickleback (Hint: Noise)

by clark in Now Hear This

The world’s seas and other aquatic environments are getting louder, thanks to us humans. The noise poses an obvious threat to animals like whales and dolphins, but how might it alter the behavior of the sea’s smaller yet equally sonically attuned creatures? Through underwater speakers, University of Bristol biologist Julia Purser serenaded three-spined sticklebacks with noise at [...]... Read more »

Exercise Your Body, Exercise Your Brain

The Key to the Defendant Apology: Say What You Mean, and Mean What You Say

by Persuasion Strategies in Persuasive Litigator

Google “public apology” and watch the results pile up. Within the last 24 hours a famous clothing designer, a city councilman, a Boston nightclub and countless others have issued apologies for their varied transgressions. We’ve covered this territory in previous posts. We’ve even laid out a pretty simple description of what constitutes a complete apology that recipients and third parties (and jurors!) are likely to perceive as sincere. So why are we talking about apology again? Is it ........ Read more »

Earthquakes And Antipsychotics

by Neuroskeptic in Neuroskeptic

According to a clever little paper just out from Italy, prescriptions for antipsychotic drugs skyrocketed in the months following a major earthquake. But there are some surprising details.On 6th April 2009, an earthquake hit L'Aquila, a medium-sized city in central Italy. Out of about 100,000 people living in the L'Aquila area, over 600 died and over 60,000 were displaced: a major disaster for the local people.Rossi et al from the University of L'Aquila looked at medication prescription in the 6........

Return of the brain-controlling zombie-ant parasitic fungi

by Mo in Neurophilosophy

A dead ant infected with a parasitic Cordyceps fungus (David P. Hughes).A team of entomologists working in the Brazilian rain forest has discovered four new species of parasitic Cordyceps fungi, which infect insects and manipulate the behaviour of their hosts in order to disperse their spores as widely as possible.The modus operandi of the Cordyceps fungi is reminiscent of the famous chest-bursting scene in Ridley Scott's movie Alien. Microscopic spores infiltrate the host via the spiracles - t........ Read more »

New family tree of worms has roots in the 19th century

by Lucas in thoughtomics

Nineteenth century biologists had a point when they divided the ringed worms into free-living hunters and sessile filter feeders. Their classification was dismissed in the 1970s, but a closer look at the genes of many different worms now shows that they were closer to the truth than their later colleagues.
The classification of worms got [...]... Read more »

Ammonoids Trapped Parasites in Pearls

by Laelaps in Laelaps

Everybody knows how oysters make pearls – a bit of sand or grit slips through the protective barrier of their outer shell, irritating the mollusk’s body, and the invertebrate encircles the invader with shell material. As it turns out, ammonoids — the extinct, coil-shelled cousins of modern squid and nautilus — made [...]... Read more »

Altica carinthiaca: moving with climate change, or simply overlooked?

by davesbrain in Dave Hubble's ecology spot

Altica carinthiaca Weise 1888 is a small (3-4mm) leaf beetle (Coleoptera: Chrysomelidae) widespread but scattered the western Palaearctic from Britain to Baikal, mainly in northern European countries; in more southerly locations it is associated with montane and submontane habitats. It was only recognised as a British species in 2000 (Cox 2000) having been confused with A. palustris and A. pusilla var. montana, although re-examination of collections has found British specimens dating back to 193........

Topical NSAIDs

by Scott in Science-Based Pharmacy

I have a mental basket of drugs that I suspect may be placebos. In that basket were the topical versions of non-steroidal anti-inflammatory drugs (NSAIDs). When the first products were commercially marketed over a decade ago, I found the clinical evidence unconvincing, and I suspected that the modestly positive effects were probably due to simply [...]...

by Erin Campbell in HighMag Blog

When I first learned about the elegant experiments of the late Ray Rappaport, I remember feeling like I was having a Zen moment. Amazing things can be learned from some of the simplest experimental designs, and this is a very calming and satisfying concept. Today’s image is from a paper using those same sea urchin eggs that Rappaport used, and provides us with a great prediction tool for determining how a cell will divide. Many cells in an embryo must divide in a certain orientation, and m........ Read more »
