The Things Living on your Toothbrush…

by Gabriel in Lunatic Laboratories

Did you remember to brush? I hope you did, but you may be throwing away your toothbrush soon. Get ready for your daily amount of gross, because have I got a scientific discovery that will make you rethink your dental hygiene. Researchers have found that “solid-head” power toothbrushes have up to 3,000 times less bacteria when compared to “hollow-head” toothbrushes.[…]... Read more »

The Learning Brain Unravelled

by Gabriel in Lunatic Laboratories

As an engineer you would think math would come easy to me, it didn’t. Funny thing though, science in general and biology in particular came very easy to me. The big question is why? Why would math, something I need to know how to do for my work and my degree, be so hard to learn? Thankfully science has stepped in to answer the question, at least partially, about why somethings can come so easy to a person and other things (like me and math) take so much longer to pick up.[…]...

The Holographic Universe [we might Live in!]

by Gabriel in Lunatic Laboratories

Are you feeling a little… flat? Well that might be because you are only in 2 dimensions. I know what you’re thinking, insane! Well first check the name of the business and second, check out the science. In fact, it may seem like a joke, but the math suggests that it could very well be true and with it could come a deeper understanding of the universe. Testing this hypothesis (which was first made in the late 90’s) has been harder to do than you might think, but that has now changed. We are........ Read more »

Correcting the Critics of Nicholas Wade & MAOA

Is Intelligence Actually Beneficial To Survival?

by Rebekah Morrow in United Academics

Research shows that more intelligent animals might not always be best suited for survival. Some researchers speculate that intelligence may be a trade-off. Fast learning may correlate with other traits, such as being less aggressive, which could weaken chances for survival. Slower learning may indicate that other choices are being made, and this variety could prove advantageous later.... Read more »

Hello Do You Believe in Dog(ers)!(source)After two years of mostly pen-pal style blogging, we're excited to share our new direction!When we first decided to create Do You Believe in Dog?, we committed to blogging back and forth about canine science for two years. We were able to celebrate achieving that goal at the recent 4th Canine Science Forum in Lincoln, UK and also reflect on the future of Do You Believe in Dog?The DYBID blog, Facebook and Twitter feeds have become vibrant places to ac........

How Stress Promotes Atherosclerosis

by Agnese Mariotti in United Academics

There is evidence that chronic stress increases the risk of atherosclerosis, but no mechanism linking the two phenomena has been demonstrated so far. Since stressful emotional states can affect the function of the immune system, Heidt and colleagues of the Massachusetts General Hospital hypothesized that stress increases the activity of inflammatory cells in the plaques facilitating their rupture, as you can read in their recently published article....

Cats Won’t Answer Your Call Or Ring You Back

by Chiara Civardi in United Academics

In a recent article, scientists proof that cats do not evidently set aside special attentions to their owners when called, even though they were able to recognize a familiar voice. Twenty domestic cats simply moved their head or their ears when called by whomever, owners or strangers, but almost no cat replied, “saying something”. They tried with everything: official names, nicknames, etc. but cats never said a word. In addition, hearing the owners’ voice did not result in a ma........ Read more »

We can Build it Better: The First Artificial Cell Network

by Gabriel in Lunatic Laboratories

How does the old saying go? Imitation, is the sincerest form of flattery? Well that is what we’ve been trying to do for a very long time, but mimicking the intricate networks and dynamic interactions that are inherent to living cells is difficult to achieve outside the cell. Unfortunately despite all our intelligence nature has had the upper hand on us for a long time. That has not changed… until now that is.[…]... Read more »

HIV Vaccine One Step Closer to Reality

by Gabriel in Lunatic Laboratories

The war on HIV, that tricky little guy has avoided every thing we could throw at it in a broad sense. Sure a few people here and there get lucky, but we have yet to actually make any sort of we're going to kick your ass headway [don't worry it's the technical term for it]. That is hopefully going to change with a new scientific discovery that has enormous implications for HIV vaccine development. Researchers have uncovered novel properties of special HIV antibodies that promise to........ Read more »

Marijuana and the Developing Brain

by Gabriel in Lunatic Laboratories

You can’t get away from it, the big marijuana debate here in the US. Is it good? Is it bad? What are other countries doing? There are also a lot of claims made about marijuana, most of which aren’t true, namely the big medical claims. Then there is the other side of that fence, what about some of the health issues that are claimed, where does science sit on that?[…]... Read more »
