Merit’s Liquidity

by nooffensebut in The Unsilenced Science

The latest SAT and ACT data suggest that America’s cognitive elite have been enjoying new geographic mobility, but difficult economic times push them out of the elite strata, contrary to a prediction of The Bell Curve by Richard Herrnstein and Charles Murray.... Read more »

You can tell [my mood] by the way I walk

by Gabriel in Lunatic Laboratories

Ever see a guy walking down the street and know he’s depressed? Or how about someone happy, with a little bounce in their step? The way we walk says a lot and by some estimates roughly 90% of what we are telling people isn’t coming out our mouth, it’s all body language. Our walk says a lot about the kind of mood we are in, but in the question of what came first our mood or our walk, researchers have now shown that it works both ways.... Read more »

Biochemical 'Memory' Can Help Bacteria to Grow

by This Science is Crazy! in This Science Is Crazy!

A new study explores ‘memory’ in E. coli to see how it impacts on their ability to grow in environments with fluctuating food sources. Recent exposure to a food source can reduce and even practically eliminate the 'lag' phase of growth when the food is reintroduced.... Read more »

How You Feel About People is Related to How You Feel About Cities

by Mark Rubin in Mark Rubin's Social Psychology Research Blog

There are numerous structural factors that influence people’s attitudes towards cities. However, these factors may be constituents of broader sociocultural “questions” that people ask about their cities.  For example, residents’ concern about the transport and entertainment venues of a city might form part of a broader social psychological concern about the potential for the city to accommodate their need to meet friends and socialize with others. Alternatively, people might focus on a ........ Read more »

Orange Corn Aims to Fight Vitamin A Deficiency

by Gabriel in Lunatic Laboratories

GMO food is still a hot button topic, honestly for no other reason than fear. Sure Monsanto is a big evil corporation, but the science is only as bad as what you do with it. In the modern fortified world we don’t think about vitamin deficiency or the horrible things that come with it, however vitamin A deficiency is a huge problem in developing countries. To combat this researchers have identified a set of genes that can be used to naturally boost the provitamin A content of corn kernels, a fi........ Read more »

Cat and Dogs: seeking solutions with sniffing canines and science

by Cobb & Hecht in Do You Believe In Dog?

Hi Mia and Julie,  First of all, I LOVE your blog! After meeting at SPARCS this past summer (summer for us in North America.. I take it summer is just beginning in Australia!), I’ve followed it closely.  You do amazing things for the promotion of  canine science. Serious love. A bit of background for the readers: I’m currently doing my PhD at Dalhousie University in Halifax, Nova Scotia in Canada, under the supervision of Dr. Simon Gadbois. Dr. Gadbois........ Read more »

The Genetic Evolutionary Arms Race

by Gabriel in Lunatic Laboratories

Genes are tricky little buggers, the stuff that makes us up has fought the test of time to make it to where we are today. It is thought that our genes changed in an attempt to outpace other life, albeit random changes.That might only be half right however, new findings suggest that there is an evolutionary arms race going on within the genome against, of all things, itself. This inherent competition of primates drove the evolution of complex regulatory networks that orchestrate the activity of ........ Read more »

“GMO” Foods (Once Again) Proven Safe

by Gabriel in Lunatic Laboratories

GMO, I shudder every time I hear someone talk about the “dangers”. It’s one of the new buzzwords that doesn’t actually mean anything, but still manages to scare people. Well a new scientific review reports that the performance and health of food-producing animals consuming genetically engineered feed, first introduced 18 years ago, has been comparable to that of animals consuming non-GE feed. Not that this will stop people from spreading fear, but it’s a start.... Read more »

Need a Kidney? Lab Grown Kidneys Coming Soon!

by Gabriel in Lunatic Laboratories

Stem cells offered the promise of having a patents own organ grown to replace a failing or damaged one. Unfortunately the road to that future has been paved with seemingly insurmountable challenges. Thankfully now we are one step closer, researchers have addressed a major challenge in the quest to build replacement kidneys in the lab. Working with human-sized pig kidneys, the scientists developed the most successful method to date to keep blood vessels in the new organs open and flowing with blo........ Read more »

Genes Smash! An Oxytricha trifallax story

by Gabriel in Lunatic Laboratories

In DNA mutation is often a bad thing. It’s sort of like building a car, there are far more wrong ways to one together than there are right ways. Still, mutation happens often which brings with it good (and more often bad) things. Usually mutation is spontaneous, it has no real rhyme or reason (in a broad sense) and while it brings things like cancers, it also can bring amazingly beneficial traits too.... Read more »

Artificial Cells: They’re alive!!

by Gabriel in Lunatic Laboratories

Frankenstein’s monster was (in the story) a scientific marvel that could not be matched. Growing up with the story, the idea of creating life where there was none was a feat that I had once thought was going to always be science fiction. Maybe this is why I was so surprised when I found out that scientists, using only a few ingredients, have successfully implemented a minimalistic model of the cell that can change its shape and move on its own....

The Kanisza Triangle: You Can’t Believe Your Eyes

by Rebecca A. Zarate in United Academics

How does the brain decide what the larger, gestalt picture is? From this demonstration, Kok and De Lange concluded it is “an interactive process between higher-order visual areas and V1, wherein activity in V1 is modulated in a highly specific way according to the perceptual hypothesis provided by higher-order areas.” In essence, higher areas of the brain (top-down processes) are making gestalt type guesses, expectations, and assumptions that affect what your senses perceive...

Epigenetics: Taking Control of the Music

by Gabriel in Lunatic Laboratories

When I try to explain epigenetics to someone, I like to use the musician metaphor. Your genes are the sheet music and how your body reads those genes, that is your body acting like a musician, making those notes it’s own. This is even more evident when you realize that all human cells contain essentially the same DNA sequence. Up until now we've had to be the audience to this genetic symphony, but new research is helping scientists take control of the music.... Read more »
