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 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 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.

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 »

Seeing Red: A New Way To Predict Preeclampsia

by Rebekah Morrow in United Academics

New Congo red test predicts development of preeclampsia with pregnant women. A large collaboration of scientists recently reported a new method of determining which women would develop preeclampsia. Urine samples were collected from more than 600 patients and mixed with a dye called Congo red. Congo red stains large clumps of proteins, but doesn’t mark smaller separate proteins.... Read more »

White or Brown: which is the better fat?

by Shefali Sabharanjak in United Academics

White adipose tissue or white fat has earned notoriety in the current obesity pandemic. But it is not right to throw white fat cells out of the window, just yet. Recent research has shown that conservation of energy-storing white fat cells can help to overcome cachexia brought on by chemotherapy in cancer patients. ... Read more »

Profiling Risk: Predicting Alcoholism In Adolescents

by Agnese Mariotti in United Academics

It appears that certain personality traits and traumatic early life events are typically associated with binge drinking in teenage years. However, the predictive power of each type of factors by itself (personality or individual history for example) is not absolute. A new study evaluated not only one single factor, but a series of psychological, genetic, and neurological elements for their ability to determine, when combined, current and future alcohol misuse in a large group of youngsters. ...
