Faith or Fiction?

by Shaheen Lakhan in Brain Blogger

Arguably, one of the greatest scenes in all of movie history is the parting of the Red Sea by Moses played by Charlton Heston in the blockbuster epic The Ten Commandments. (The awe inspired by the portrayal of the miracle during the Israelites’s exodus from Egypt is matched only by the awe that movie special [...]... Read more »

Competing interests at medical journals: industry sponsored trials boost impact factors

by Helen Jaques in In Sickness and In Health

These days medical journals are rigorous when it comes to getting researchers to declare any associations with industry that might influence how a trial is reported. Before agreeing to publish a paper, many of the top medical journals require authors to sign a comprehensive conflicts of interest form that outlines any financial or personal relationships [...]...

Anthroposophy & It's Medicinal Application

by John Wayland in The Darwin Tribune

Anthroposophy isn't a word many psychology students will ever come across. Additionally, it's one of those funny words that I might happen to mispell throughout this blog - so I apologise to any fans of Anthroposophy before hand. Some may know that certain aspects of psychological thought are tied into philosophy. The issue I remember was although psychologists have learnt a great deal about consciousness, will we actually know what it is to be cat? Or does everyone see and "experience" the........

Climate Change and the Importance of Maintenance Breeding

by Matthew DiLeo in The Scientist Gardener

Variety IR8 is the original "Miracle rice" of the 1960s. This carefully-crafted variety has a stunted, semi-dwarf phenotype, which increases it's harvest index (the proportion of grain biomass to total biomass), and allows it to resist lodging (falling over into the mud), even when heavily fertilized. As with wheat, the creation of dwarf varieties of rice played a major role in the enormous yield gains of the Green Revolution.

But now it's in trouble!
IR8 originally produced yields o........ Read more »

Friday Weird Science: fMRI and Female Orgasm, that’s SO been done.

by Scicurious in Neurotic Physiology

So apparently, everyone is getting all hot n bothered over the fact that, at SfN, they are going to do a video of women stimulating themselves to orgasm…in an fMRI. Of their BRAINS, obviously. Please, this conference is not NSFW! Sci is very excited to see the videos (heh, heh…) but moreso to see the [...]... Read more »

The grand challenges of Earth system science and sustainability

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

In the Policy Forum of today’s issue of Science, a research team that includes recent Nobel laureate, Elinor Ostrom, issued a call for innovative interdisciplinary approaches to confronting major environmental challenges:
Tremendous progress has been made in understanding the functioning of the
Earth system and, in particular, the impact of human actions. Although this
knowledge can inform management [...]... Read more »

Animal Signalling Theory 101 – The Handicap Principle

by Anne in A Replicated Typo 2.0

One of the most important concepts in animal signalling theory, proposed by Amotz Zahavi in a seminal 1975 paper and in later works (Zahavi 1977; Zahavi & Zahavi 1997), is the handicap principle. A general definition is that females have evolved mating preferences for males who display exaggerated ornaments or behaviours that are costly to maintain and develop, and that this cost ensures an ‘honest’ signal of male genetic quality.

As a student I found it quite difficult to identify a work........ Read more »

Learning from toys – again

by Jan Husdal in

Is China really to blame for the 2007 recall crisis, or are the drivers and causes of this crisis originating from much closer to home? What can we learn from the toy industry? Much of the focus has been on China and its contractors, but China is not solely to blame, as many of the risk drivers come from the companies who outsourced the production, not the Chinese manufacturers. ...

The algae’s accent

by Lucas in thoughtomics

Different cultures around the world have sought to explain the multitude of human languages. In the Bible you can find the story of the Tower of Babel, set in a time when all of humanity spoke one language. The unity that this common language instilled allowed these people to do great things. But when they [...]... Read more »

Feeling Energetic

Crashing surf and surging currents make for dramatic seaside scenery. These high-energy environments are also increasingly eyed for producing electricity, however – and that trend highlights the need for more study of the ecological implications of ocean energy projects, argues a new study.

Antibodies neutralize viral infectivity inside cells

by Vincent Racaniello in virology blog

Antibodies are an important component of the host defense against viral infection. These molecules, produced 7-14 days after infection, neutralize viral infectivity, thereby limiting the spread of infection. Antibodies are thought to neutralize viral infectivity in several ways: by forming noninfectious aggregates that cannot enter cells, or by blocking virion attachment to cells or uncoating [...]...

Hitching a Ride on a Trilobite

by Laelaps in Laelaps

Fossil skeletons are static things. They no longer grow or respond to the stresses and strains of life. Tucked away on shelves or propped up on intricate armatures, fossil bones and other mineralized hard parts show us the shape of ancient organisms, but we can only perceive whispers of the lives those remains represent.
The way [...]... Read more »

Perfluorinated chemical exposure from food wrappers

by Ashartus in exposure/effect

Perfluorinated chemicals, which are organic molecules with several fluoride atoms attached to the carbon chain, have had a fair amount of attention from environmental scientists over the past several years, primarily due to their long persistence in the environment. They’ve been used in a large number of consumer products – probably best known for non-stick [...]... Read more »

Unexpected Horned Dinosaur Reveals Complex Evolutionary Pattern

by Brian Switek in Dinosaur Tracking

In many of the books about dinosaurs I read as a child, the evolution of horned dinosaurs (ceratopsians) looked pretty straightforward. Early, lanky forms such as Psittacosaurus were succeeded by a miniature precursor of later types—Protoceratops—before generating the array of large, spiky ceratopsid dinosaurs such as Triceratops and Styracosaurus. Yet, as more discoveries have been [...]... Read more »

Social skills training for children with autism: not all group therapies are created equal

New Possibilities for Depression: A MAP Kinase regulator

One of the problems with depression as a disorder is that the symptoms never seem to manifest the same.
