# Provided Examples vs. Generated Examples

For learning declarative concepts in a domain and then identifying those concepts in novel real-world situations, provided examples proved to be better than student-generated examples for both long-term learning and for instructional efficiency. The second experiment in the study replicated these findings.... Read more »

# Observation of quasi-periodic solar radio bursts associated with propagating fast-mode waves by C. R. Goddard et al.*

Flaring activity on the Sun triggers waves and oscillations in the solar corona. The study of these waves and oscillations allows comparisons to magnetohydrodynamic (MHD) theory and modelling to be made, and seismological inversions based on this comparison allow local plasma parameters to be measured indirectly (e.g. De Moortel & [...]...

# Suicidality in children and young adults with 'high-functioning' autism

"Consistent with the previous findings, [the] rate of suicidality is higher in individuals with ASD [autism spectrum disorder]."That was one of the conclusions reported in the paper by Sevcan Karakoç Demirkaya and colleagues [1] (open-access) yet again touching on a most important topic when it comes to autism, particularly the part of the autism spectrum labelled as 'high-functioning'. Personally, I'm not a great fan of the 'functioning' description typically added to autism to ........ Read more »

# Antibiotic cream is NOT 100% effective in preventing Lyme disease

A topical antibiotic cream applied to tick bites did not perform any better than placebo in preventing Lyme disease, according to results of a randomized clinical trial conducted in Europe.  The study was published in Lancet Infectious Diseases.I wasn't planning to blog about the study, but I changed my mind after a reader emailed me a link to a news article reporting that the antibiotic cream was 100% effective.  The lead investigator even claimed, "None of the test subjects went on t........

# No Need To Worry About False Positives in fMRI?

Earlier this year, neuroscience was shaken by the publication in PNAS of Cluster failure: Why fMRI inferences for spatial extent have inflated false-positive rates. In this paper, Anders Eklund, Thomas E. Nichols and Hans Knutsson reported that commonly used software for analysing fMRI data produces many false-positives.

But now, Boston College neuroscientist Scott D. Slotnick has criticized Eklund et al.'s alarming conclusions in a new piece in Cognitive Neuroscience.

In my view, ... Read more »

# Yang-Mills theory paper gets published!

Exact solutions of quantum field theories are very rare and, normally, refer to toy models and pathological cases. Quite recently, I put on arxiv a pair of papers presenting exact solutions both of the Higgs sector of the Standard Model and the Yang-Mills theory made just of gluons. The former appeared a few month ago […]... Read more »

# ﻿Believe in miracles... and yourself

End of the year is a very special time as Holiday lights melt away our inner Grinch and we start to believe in miracles and new beginnings. ​Belief is not a religious phenomenon. It is our way of coping with the future and finding existential meaning. Scientific studies show that belief in miracles contributes to greater life satisfaction. Belief in science and technological progress can make people satisfied with their lives even more. The stronger the sense of personal control, the higher s........ Read more »

# The Myth of "Darwin's Body-Snatchers"

Did Charles Darwin's thirst for skulls contribute to the near-extinction of the Aboriginal Tasmanian people?

If you believe certain creationists, Darwin sought examples of Tasmanian skulls in order to prove that this unfortunate race was a 'missing link' between humans and apes. However, according to John van Wyhe in a new paper called Darwin's body-snatchers?, this story has zero basis in fact.
As a Darwin scholar, I thought I had heard all the myths concerning Charles Darwin but on... Read more »

# Why we have not met Aliens yet?

A huge of number of people keeps on thinking about the existence of some other intelligent beings in the universe but still we have not met any aliens. Why?

Earth is rare

Earth is special planet

One of the reasons that we have not met aliens is that Earth is rare and there is nothing just like Earth in the universe. In this regard, Paleontologist Peter Ward and astronomer Donald Brownlee presented the Rare Earth Hypothesis about 17 years ago.

According to the Rare Earth Hypothesis, t........ Read more »
