Sarahsaurus Helps Revise Ideas of Dinosaurian Success

by Brian Switek in Dinosaur Tracking

Compared to some of its later, gargantuan cousins, the 190-million-year-old sauropodomorph dinosaur Sarahsaurus aurifontanalis was a rather tiny herbivore. Only 14 feet long, this dinosaur lived in the early days of the Jurassic, and, according to a team of paleontologists led by Jackson School of Geosciences paleontologist Timothy Rowe, this newly-described dinosaur from Arizona does [...]...

Simple Jury Persuasion: A Collision of Values and Attributions

A close look at experimentally evolved flies

by Graves in Down the Cellar

There is a potentially exciting new paper in Nature that challenges entrenched ideas about how adaptation proceeds.  I say potentially, because I have some serious misgivings I'd like to share. But first, a brief overview of the Burke et al. paper.

Michael Rose's lab has had a long-term experimental evolution project with Drosophila melanogaster running for about 20 years.  This is an amazing ... Read more »

When Pseudo-Crocs Walked Tall

by Laelaps in Laelaps

Fossil tracks – the clear imprints of living creatures – have often sparked the imagination of those who have found them. When, in 1802, a young boy found footprints in stone on his family’s South Hadley, Massachusetts farm some of the tracks wound up as a doorstop. Visitors joked that the family must have raised [...]... Read more »

Unlocking nano secrets

by sciencebase in Sciencebase Science Blog

An open or shut case for nanotechnology secrets Should nanotechnology R&D be more open to allow it to thrive in the commercial world, or should companies working in this field be more secretive? Paradoxically, the answer seems to be that keeping secrets stifles innovation and reduces patent success. According to Associate Professor of Management at [...]Unlocking nano secrets is a post from: Sciencebase Science Blog

Comparative Effectiveness for Populations and Individuals

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Yesterday, on my flight to San Diego to attend the 28th Annual Scientific Meeting of The Obesity Society, I had the opportunity to catch up on some of my reading.
Two recent articles in the Journal of the American Medical Association (JAMA) caught my attention, as they related to topics that I have recently blogged about.

Can we agree F-st has run its course?

by TwoYaks in Gene Flow

Other scientists out there! Hi. Can we agree that Fst, as wonderful as it's been, has run its course? It was a good idea - a great first crack at population genetics. When Wright came up with it, it was a wonderful idea. And for some applications - those where heterozygosity is generally low (I'm looking at you allozymes) - it works quite nicely. But once you're outside the Hs of .4 to .6, your ... Read more »

Repost: The ancestor of the hairball

by Becky in It Takes 30

While we were playing “cite the oldest paper“, Pam Silver suggested this paper (Srb, AM and Horowitz, NH, 1944. The ornithine cycle in Neurospora and its genetic control.  J. Biol. Chem 154 129-139), as a distant antecedent of the field we now call systems biology. Published only three years after Beadle and Tatum used Neurospora [...]... Read more »

Amplifying differences to develop our own identity and mitigate sibling rivalry

Sibling differentiation, identity development, and the lateral dimension of psychic life From Journal of the American Psychoanalytic Association Last week in UK politics some commentators remarked how “brotherly love took a backseat to a lust for power” as the Miliband brothers competed against each other for the position of Labour party leader.

The evolutionary roots of laughter

by BPS Research Digest in BPS Research Digest

To evolutionary psychologists, the noise made by gorillas, chimps and bonobos when you tickle their feet is no laughing matter. These distinctive vocalisations suggest that rather than evolving separately, laughter evolved in a shared common ancestor before becoming tailored in each primate species, including humans.

To find support for this idea, Diana Szameitat and her colleagues scanned the brains of 18 men and women whilst they listened to the sound of human tickle-induced laughter as well ........ Read more »

Sleep more to lose weight? Read this before

by Akshat Rathi in The Allotrope

Before this piece of research gets out of hand due to shoddy science journalism, it does not conclude that people should sleep longer to lose weight. The paper is titled "Insufficient sleep undermines dietary efforts to reduce adiposity", which means that if you are person dieting to lose fat then sleeping less will undermine your efforts.

The study compares a group of 10 who were dieting, 6 persons slept for 8.5 hours every night for two weeks and similarly, 4 persons slept for 5.5 hours every........ Read more »

Measuring resilience to climate-change driven crop failure

by Noam Ross in Noam Ross

A number of news outlets have picked up on a new article in Environmental Research Letters by Andy Challinor and a team at the University at Leeds.  The standard headline is "Crop Failures to Increase With Climate Change," but I think the much more interesting part of the research is the author's creation of a vulnerability index based on the historical crop data in China.  Essentially, they looked at periods of drought in the past, and examined how well farmers were able to mitigate t........

Unique Strains of Yersinia pestis Caused the Black Death

Internal forward models -- New insight or just hype?

by Greg Hickok in Talking Brains

In case you haven't noticed, the concept of internal forward models -- an internal prediction about a future event or state -- are all the rage. The concept comes out of the motor control literature where one can find pretty solid evidence that motor control makes use of forward predictions of the sensory consequences of motor commands (e.g., check out the seminal paper by Wolpert, Ghahramani, & Jordan, 1995). These concepts have been extended to speech (e.g., Tourville et al. 2008; van Wassen........ Read more »

More on genetically modified (Bt) corn: Is it an economic boon to all corn farmers?

by Phil Camill in Global Change: Intersection of Nature and Culture

There’s a new paper in this week’s issue of Science that suggests that growing a landscape mixed with genetically modified (GM) Bt corn and non-GM hybrid varieties of corn can be mutually beneficial to all corn farmers.
Why?  They argue that the populations of GM corn knock down the populations of insect herbivores enough that, on [...]... Read more »

Psycasm - Siesta - It sounds like Fiesta, but isn't.
