Apocalyptic climate change warnings can be counter-productive

by BPS Research Digest in BPS Research Digest

Many people believe implicitly that the world is fair, that bad things by and large don't happen to good people. When presented with evidence to the contrary, they ignore or downplay it. According to Matthew Feinberg and Robb Willer, this is exactly what happens when such people are presented with dire warnings about global warning.

Feinberg and Willer had 97 undergrads read one of two versions of a newspaper-style article about global warming and its likely consequences. Both articles began in........ Read more »

Statistics: Friend or Foe?

by zacharoo in Lawn Chair Anthropology

In this week's Science, Greg Miller describes recent uproar about a study that claims to have scientific support for the existence of extrasensory perception (ESP). Of course, ESP being in the realm of the paranormal, it ought to be somewhat outside the purview of Big Science.But who cares about ESP?! What comes under scrutiny is statistics, the mathematical theory underlying hypothesis testing. And inference. The brief story is worth a read, as it cites statisticians on what these statistical t........ Read more »

Is abortion associated with mental illness?

by PalMD in White Coat Underground

Anti-abortion groups, having largely failed to convince the American public that abortion is morally abhorrent, have tried to shift the debate to their concern about women’s health.  The same groups who would forbid abortion after rape or incest, or when the mother’s life is endangered claim to be saving women from “post-abortion syndrome”, a mythical [...]...

Jumbo Shrimps: Why Mega-Mammals Still Looked Puny Next to the Biggest Dinosaurs

Imagine a rhinoceros. For the sake of argument, let’s say it’s a white rhinoceros. Don’t worry if you can’t envision every little anatomical flourish in your mind. We’re going to modify this beast a bit.

On the relation between auditory-motor area Spt and conduction aphasia

by Greg Hickok in Talking Brains

Conduction aphasia is characterized by relatively frequent phonemic speech errors with self-correction attempts and difficulty repeating speech verbatim; comprehension is relatively well-preserved. The classical account holds that conduction aphasia is caused by damage to the arcuate fasciculus. However, we have been arguing for some time that conduction aphasia is caused by damage to area Spt -- a functionally defined region in the vicinity of the left planum temporale that exhibits auditory-........

A Mouse Model of XMRV Pathogenesis?

Through studying viral pathogenesis we seek to understand mechanistically how viral infection and replication causes disease in a particular host. This of course will be subject to a number of complex variables involving both the host and the virus such as: dose; genotype; virus receptor distribution of host tissues;the ability of the virus to replicate [...]...

What's the difference between an oceanographer and a marine biologist?

by Heather Wright in Plankton Biogeography

In a recent article entitled: Marine Sciences: from natural history to ecology and back, on Darwin's shoulders - Boero brings up the historical differences between biological oceanography, marine biology and ecology. It's time we turn our attention to this topic for discussion and opinions. I believe in both practice (applied science) and philosophical approach (or culture) that there is a distinct difference between an oceanographer and a marine biologist. ... Read more »

What the Tiger Mother Left Out

by David Berreby in Mind Matters

A cognitive scientist friend of mine made a good point the other day about Amy Chua's assertion that "nothing is fun until you're good at it." It is, he said (and I should have seen right away) not true. Lots of things are fun before you're good at them. Potching around with a guitar or a tennis ...Read More

Khat to the Chase

Of mephedrone, bath salts, and impaired driving.

 Automobile accidents are the ninth leading cause of death worlwide, according to the World Health Organization (WHO). More than a million people are killed on roads annually, and that number could rise to 2.5 million by 2020. WHO estimates that traffic accidents cost developing countries an astonishing 1-2 % of their gross domestic product (GDP).

For years now, police and public health officials have puzzled over the alarming number of tr........ Read more »

The Rekhmire tomb elephant revisited: island dwarf or Syrian giant?

by Darren Naish in Tetrapod Zoology

I really enjoyed the long and involved debate that followed my article on the small elephant depicted on the wall of Rekhmire's tomb. Thank you to (just about) everyone who contributed. As I tried to make clear in the actual article, we'll likely never know the truth of the matter, and this whole exercise should be seen as a bit of fun speculation [image below © Alessando Mangione and Marco Masseti].

Killer Whales Kill Whales

by Sam W in From C to Carnivore

Aren’t they adorable? Orcas are beautiful animals and people often try to portray them as nicer animals than they really are (most notably anyone who thinks it is a good idea to keep these animals in an aquarium). Really though, orcas are nasty. That’s not to judge, all predators are essentially nasty. They eat other animals (but then again, so do I).... Read more »

Neandertal admixture, revisiting results after shaken priors

by Razib Khan in Gene Expression

After 2010′s world-shaking revolutions in our understanding of modern human origins, the admixture of Eurasian hominins with neo-Africans, I assumed there was going to be a revisionist look at results which seemed to point to mixing between different human lineages over the past decade. Dienekes links to a case in point, a new paper in Molecular Biology and Evolution,  An X-linked haplotype of Neandertal origin is present among all non-African populations.
