Assemblages: 50 Years Later, We Know Nothing About Them

by Dr. Jekyll in Lunatic Laboratories

You would think we learn about every part of a cell in biology, but we really don't. Case in point, about 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. The reason you probably haven't heard of these structures is because scientists really don't know what they do even 50 years later. Although they do have an idea about them, these shifting cloud-like collections of proteins are believed to be crucial to the life of a cell, and will ideally offer a new approach to disease treatment....

The Ever Mutating Ebola Virus

by Dr. Jekyll in Lunatic Laboratories

Ebola has a nasty reputation for the way it damages the body. It's rightfully earned when you look at the death rate. But when you look at the actual details of an Ebola infection, a surprising fact surfaces: The virus isn't what ends up killing you, it's your own immune system. Sure they are trying different ways to outsmart the virus, but it's mutating... quickly. In fact, scientists have rapidly sequenced and analyzed more than 99 Ebola virus genomes. The hope it to better understand the enemy and possibly outsmart it.... Read more »

The Things Living on your Toothbrush…

by Dr. Jekyll 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 Dr. Jekyll 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 Dr. Jekyll 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 officially checking to see if our universe is a hologram![…]... Read more »

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 »

Do You Believe in Dog? A New Ball Game

by Cobb & Hecht in Do You Believe In Dog?

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 access canine science studies and thoughtful commentary. We are pleased and proud of the space we have created and the community who enjoy it. We're as committed as ever to helping people access the canine science conversation, and moving forward, we've decided to open up DYBID as a space where other canine science practitioners can share their findings and thoughts.  What you can expect Guest contributors Following the format you've enjoyed in earlier guest posts (like Dog training: do you get the timing right?, Take a walk on the wild side: dingo science  and Black dog syndrome, a bad rap?) researchers and students of canine science are welcome to submit short posts to DYBID based on peer-reviewed research. We're hoping posts will focus on research either presented at academic conferences or published in scientific journals. If you have an idea for a post, check out the Contributors page for more details, and be in touch! Canine science highlights We'll continue our usual presence on Facebook and Twitter, and here on the DYBID blog we'll post fortnightly updates highlighting the canine science that we've been following in the previous two weeks (blog posts, scientific studies, websites, etc.). This slideshow is our first attempt at sharing Canine science highlights. We have used Storify so you can quickly flip through and click on anything you want more info about. [View the story "Do You Believe in Dog? [01-15 August 2014] " on Storify]Where in the world are Mia and Julie?To simplify our Twitter presence:Mia will primarily manage the @DoUBelieveInDog feedJulie will continue being active on @DogSpies, as well as at her Scientific American Blog, Dog Spies, and her dog research group @Dog_CognitionYou can also stay in touch with Mia at @AnthroZooRG (her research group), @HumanAnimalSci (a podcast featuring the latest from Anthrozoology) and @WorkDogAlliance...

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 marked behavior: the cat response was equal....

We can Build it Better: The First Artificial Cell Network

by Dr. Jekyll 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 Dr. Jekyll 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 help eliminate HIV.[...]... Read more »

Canine Science Forum 2014 - we come full circle!

by Cobb & Hecht in Do You Believe In Dog?

Aw - it's Us @ CSF2014! Thanks Tamás Faragó :)Dear Julie,while you've been off enjoying the fjords of Norway and I've been recovering from six legs of long haul flying with a three year old as hand luggage, I thought I'd put up a quick post to recap the wonderful week in Lincoln, UK that was the (Feline and) Canine Science Forum 2014.Such a fun, stimulating, inspiring week comprising the Feline Science day (Monday), public lecture by James Serpell (rhymes with purple) on Monday evening, Canine Science Forum (Tue-Wed-Thu), including the wonderful gala dinner at Lincoln Castle on Wednesday night and finally, the Companion Animals: Human Health & Disease day (Friday).If anyone out there happened to miss it, we live tweeted nearly all of the presentations so you can easily catch up on all the great thoughts via the magic of Storify here. Feline Science Day:[View the story "Feline Science Forum 2014" on Storify]Public lecture by James Serpell:[View the story "Feline & Canine Science Forum, Public Lecture: James Serpell" on Storify] Canine Science Forum Day 1:[View the story "4th Canine Science Forum - Lincoln UK 2014 - Day 1" on Storify] Canine Science Forum Day 2:[View the story "4th Canine Science Forum - Lincoln UK 2014 - Day 2" on Storify]Which, of course, included us being real life #scientists (we don't make this stuff up!): You talked about Project: Play with Your Dog and the role that citizen science can play in canine science.Nancy Dreschel (now on Twitter at @ndreschel) presented the key findings from our collaborative meta-analysis looking at canine salivary cortisol.And I explored if using group averages is really the best way to determine and analyse the stress and welfare experience of working dogs (and my points were relevant to all animals!). Then we drank wine in at a castle. Which was a mighty fine way to end that day.
