What do you see when you look into a squid’s eye?

by Mike Mike in Cephalove

If the squid had her way, nothing! Cephalopods are good at camouflage – their color and texture-changing skin is one of their claims to fame. This is all well and good for species of animals who live on or near the ocean floor, where there are things to blend in with – in the open [...]... Read more »

“What a tuuune!” – A Scientifically Good Song

by Ben Good in B Good Science

It’s a Saturday night, you are about to hit the town. There are many things that can affect how good the impending night out is going to be, the quality of the company, amount of alcohol consumed, making it home with all your possessions. The music also obviously plays a key part in the night and scientists have … Read more...

Cartoon – Alcohol and Aggression

by Shaheen Lakhan in Brain Blogger

Judging by all the destruction caused by the test subject, drinking more does make one more aggressive. A recent study published in the Journal of Studies on Alcohol and Drugs found a positive correlation between alcohol dose and aggression in human subjects. Aggressiveness was measured by shock intensity and duration administered to one’s “opponent” in [...]... Read more »

Out of my mind: the tendency to ruminate about the past may have upside

Think about a time when you did something that you really regretted… Now try to stop.  When we think about something that happened to us in the past, the emotions that were originally elicited by that event come rushing back.  … Continue reading →... Read more »

Third hand smoking - Can we ban this poison already?

by James Byrne in Disease Prone

I’m not going to write a post on why smoking is bad, it’s too obvious and if you don’t understand why then your probably never going to find this post anyway. I’m not even going to talk about second hand smoking, ie. blowing your death cloud at me on the street. Again it’s obvious why it’s bad and may even be worse than smoking the cigarette itself as second hand smokers don’t get the benefit of a filter. No, this post is about third hand smoking, a fun new way smokers can harm th........ Read more »

Y chromosome reveals more about the Filipinos

by nath in Imprints of Philippine Science

“There is a great difference of opinion among ethnologists who have seen these Negritos, as to the race to which they belong”, S. Kneeland writing in 1883 for Science [1]. He further adds that “they are not far above such an ape as might have been the ancestors of man, with the cerebral convolutions of the orang, [...]... Read more »

The religious hypochondriacs of Nairobi

by Tom Rees in Epiphenom

In 2006, the African Population and Health Research Center began a 5-year study into the health of older people (50 years and up) living in two Nairobi 'informal settlements' (aka slums, as pictured). Among other things, they wanted to know how healthy the people living there felt.

So, one of  the questions they asked was simply this: "In general, how would you rate your health today?"

They found that non-Catholic Christians were the most likely to rate their health highly, and Muslims th........ Read more »

Neury Thursday: Basic Sleep Mechanisms

by Allison in Dormivigilia

Neuroscientists have better characterized neurotransmitter signaling during specific stages of sleep. Though this information is certainly not ground-breaking, we should, nonetheless, be grateful that there are still scientists out-there that are proponents for strengthening our current data set rather than always aspiring for some radical, scientific finding....

Do people follow trains, or do trains follow people? London’s Underground solves a riddle

by Tim De Chant in Per Square Mile

Transit oriented development is all the rage in urban planning these days. Proponents claim new transit coupled with mixed-use zoning will ignite growth in otherwise struggling areas. Detractors claim running new lines to low-density neighborhoods will leave cities burdened with white elephants. Overall, reality is probably somewhere in between, but transit and population density is [...]... Read more »

“Did You Pack Your Own Bags?” and other pointless airport security questions…

Giant club-winged pigeons and ninja ibises: clubs, spurs, spikes and claws on the hands of birds (part III)

Time to finish one of those long-running series of Tet Zoo articles: at last, the long-awaited, much anticipated third and final instalment in the series on the clubs, spurs, spikes and claws present on the hands of numerous neornithine bird species. If you haven't done so already, do check out the previous parts here (on hand claws in general, and carpal spurs and knobs in waterfowl) and here (on carpal spurs in charadriiforms).

Did Dinosaurs Die Out Because Males Couldn’t Find a Date?

by Brian Switek in Dinosaur Tracking

What caused the end-Cretaceous mass extinction is one of the greatest mysteries of all time. Paleontologists have racked up a long list of victims—including the non-avian dinosaurs—and geologists have confirmed that a massive asteroid that struck the earth near the modern-day Yucatan peninsula was probably the extinction trigger, but just how that impact translated into [...]...

New breast cancer ‘accelerator’ gene tracked down

by Cancer Research UK in Cancer Research UK - Science Update

Genes are the ‘instruction manual’ that tell our cells what to do, encoded within the DNA found in virtually every single cell in the body.  Some genes tell cells to start multiplying – essential for replacing dead or damaged cells – while others tell them to stop. The ‘go’ genes are known as oncogenes and, [...]... Read more »

why we rule the land of the blind robots

We might not be able to beat a natural language search engine or a supercomputer able to crunch every last possible move in a game of chess, but there’s one area where we easily leave just about any machine in the dust. That area? Visual recognition of course. As we saw once before, no computer [...]... Read more »

Writing Your Worries Away

by mperr in Promega Connections

Experiencing sweaty palms, a rapid heart rate and nausea shouldn’t be the standard response before taking an important exam. However, for many students this has become a debilitating reaction when the pressure to perform academically affects their test scores. I became more aware of this situation when my 13-year- old niece started “choking under pressure” [...]... Read more »
