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 »

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... Read more »

Mindful parenting can be defined as when "parents intentionally bring moment-to-moment awareness to the parent-child relationship" or "acting with awareness." There are certain qualities and skills that must be developed in order to accomplish this, but it is worth it. Mindfulness in general has been associated with:
More positive emotion
Less anxiety and depression
Greater relationship satisfaction
Less relationship stress
Brain activity associated with greater emotion regulation.
There are ........ Read more »

Judging by all the destruction caused by the test subject, drinking more does make one more aggressive.

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 »

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 »

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 »

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 [...]...

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 »

Experiencing sweaty palms, a rapid heart rate and nausea shouldn’t be the standard response before taking an important exam.
