Feathers stem cells provide new insight into the morphogenesis process
by beredim in Stem Cells Freak
A new study by researchers at the University of Southern California (USC), led by Professor Chuong Cheng Ming, reveals how stem cells contribute to the unique and complex patterns bird feathers have. Surprisingly, the study has implications in the field of regenerative medicine, say the researchers.Read More... Read more »

Tartaglia-Pascal triangle and quantum mechanics
by Marco Frasca in The Gauge Connection
The paper I wrote with Alfonso Farina and Matteo Sedehi about the link between the Tartaglia-Pascal triangle and quantum mechanics is now online (see here). This paper contains as a statement my theorem that provides a connection between the square root of a Wiener process and the Schrödinger equation that arose a lot of interest [...]... Read more »

Confirmation of Einstein’s general theory of relativity in extreme conditions
by Usman Paracha in SayPeople
Main points:
Astronomers have found that the gravitational waves are produced even in the spacetime when the two stars, in the extreme conditions, move around each other. This is the proof of the Einstein's gravity theory in the one of the most extreme conditions yet studied.

how to shield yourself in a vacuum, sci-fi style
by Greg Fish in weird things
In a fair bit of science fiction, we see advanced alien species use some sort of shielding to walk around other planets or survive being ejected into space. Something around them flickers and a protective invisible bubble is raised, protecting them from a horrible death by dehydration as all the fluid in their bodies effectively boils away. As it turns out, that’s actually possible. [...]... Read more »

White Matter Changes in Schizophrenia
by William Yates, M.D. in Brain Posts
Schizophrenia is a disabling brain disorder characterized by psychotic symptoms such as hallucinations and delusions.Schizophrenia has a prevalence rate of about 1% of the population with relatively stable rates across nations and cultures.Early brain imaging studies focused on regional evidence of brain atrophy primarily in brain gray matter. However, with the development of diffusion tensor imaging, there is a growing body of research examining white matter changes in schizophrenia. &nbs........ Read more »

Newborn Stars and their Effect on the Universe
by Jason Carr in Wired Cosmos
When galaxies form new stars, they sometimes do so in frantic episodes of activity known as starbursts. These events were commonplace in the early Universe, but are rarer in nearby galaxies. During these bursts, hundreds of millions of stars are born, and their combined effect can drive a powerful wind that travels out of the … Read More →... Read more »

Overemphasis on Theory Development Is Damaging Organizational Psychology
by Richard Landers in NeoAcademic
In a recent article appearing in Organizational Psychology Review, Pillutla and Thau[1] make some very strongly worded arguments about the role of theory development in psychological science. I’ll start exploring their paper with a quote in their own words: The state of [industrial/organizational psychology] and its obsession with novel theoretical contributions is antithetical to the goals of [...]

Challenging the dogma that animal studies of spinal cord injury can’t be replaced

Spinal cord injuries can lead to permanent disabilities such as paralysis. Research in rats and mice for new treatments involve severing nerve fibres, which can cause moderate or severe suffering. Professor Sue Barnett, University of Glasgow, who is a 3Rs Prize 2012 runner up, writes about an in vitro technique, funded by NC3Rs, to replace the use of rodents in her laboratory.... Read more »

Two Water Worlds for the Price of One
by Perikis Livas in Tracing Knowledge
Astronomers have found such a planetary system orbiting the star Kepler-62. This five-planet system has two worlds in the habitable zone – the distance from their star at which they receive enough light and warmth for liquid water to theoretically exist on their surfaces. Modeling by researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) suggests that both planets are water worlds, their surfaces completely covered by a global ocean with no land in sight....

Rivers Carry Away Waste Heat Form Power Plants at a Cost to the Environment
by dailyfusion in The Daily Fusion
Two computer models developed by the scientists from the University of New Hampshire show a detailed picture of how thermal power stations interact with climate, hydrology, and aquatic ecosystems. For example, models suggest that while rivers serve as “horizontal cooling towers” that provide an important service to the regional electricity sector, this comes at a cost to the environment....

Unique Chemistry Reveals Eruption of Ancient Materials Once at Earth’s Surface
by Perikis Livas in Tracing Knowledge
An international team of researchers, including Scripps Institution of Oceanography, UC San Diego, geochemist James Day, has found new evidence that material contained in oceanic lava flows originated in Earth’s ancient Archean crust. These findings support the theory that much of the Earth’s original crust has been recycled by the process of subduction, helping to explain how the Earth has formed and changed over time....

Prenatal valproate exposure and autism: reloaded
by Paul Whiteley in Questioning Answers
When does the the term 'correlation does not equal causation' become a moot point? It's a question I've often pondered, having discussed the issue quite a few times on this blog for all manner of correlations and associations linked to autism (sorry, the autisms).The weight of the heart @ Wikipedia Is there, for example, a recognised tipping point where the weight of evidence correlating A with B might actually lead to the consensus that A causes B either wholly or partially?Yes, I kn........
