I Am Not This Body
by Perikis Livas in Tracing Knowledge
Every time I look at my face in a magnified mirror in a hotel bathroom, I jump back in surprise. Seen closely, my skin looks like the surface of a strange planet. Ridges and canyons pock my chin and lips. Forests of tiny hairs grow from my ear lobes. Unnoticed pimples rise from my nose like volcanoes. A sheen of oil coats the landscape. I half expect to see alien creatures living in minute settlements in my dimples or roving the great plains of my cheeks — and could I look at higher magnif........ Read more »

Friday Roundup: This Week's Wildlife Links (May 17th, 2013)
by David Steen in Living Alongside Wildlife
This article could use a little more reflection about working alongside potentially dangerous animals and a little less sensationalism. But, it's still an incredible story: I was swallowed by a hippo.
Who knew? Snakes like hot springs too.
The Roundup from a couple weeks ago featured amazing pictures of a pod of Orcas attacking a group of Sperm Whales. This week's unlucky victim is a dolphin.

Colour costs crickets
by Zen Faulkes in NeuroDojo
You probably don’t feel tired when you get a tan.
You probably think your friends feel more or less fatigued depending on whether they are dark skinned or fair skinned (like myself).
We know that differences in colour are important lots of other species besides humans. They can play a big part in an animal’s ability to blend into the surrounding environment, for instance. What might be less appreciated is that being a certain colour might take energy. After all, many colours in animals are........ Read more »

Is there a relationship between age and ethnic prejudice?
by Doug Keene in The Jury Room
As you have probably noticed, we read a lot of research here at The Jury Room. We are looking for nuggets of knowledge or pearls of wisdom we can apply to our day-to-day practice of litigation advocacy. If you’ve read our work on generations you likely already know there is a relationship between age and [...]

CMS harbors new physics beyond the Standard Model
by Marco Frasca in The Gauge Connection
In these days is ongoing LHCP 2013 (First Large Hadron Collider Physics Conference) and CMS data seem to point significantly toward new physics. Their measurements on the production modes for WW and ZZ are agreeing with my recent computations (see here) and overall are deviating slightly from Standard Model expectations giving Note that Standard Model is alive and […]...

Fitness Level and Baseline Concussion Symptoms
by Stephen Stache in Sports Medicine Research (SMR): In the Lab & In the Field
Take Home Message: Fitness level may influence baseline concussion symptom reporting with fitter individuals reporting fewer concussion symptoms. Athletes also appear to report more concussion symptoms when reporting after exercise.
Baseline testing in concussion management, including graded symptom assessment, has become commonplace in multiple sports on almost every level of competition. Different assessment tools (e.g., Sideline Concussion Assessment Tool [SCAT3], Immediate Post-Concussi........ Read more »

Angelina no longer has them. Does that mean I should get rid of them too?
We love them and yet we hate them. They get censored, augmented, reduced, replaced, covered, exposed. They get grilled, occasionally, but those are not the ones I'm talking about. We want to see them and yet we pretend we don't. We criticize them and yet we forget what they are made for, the most beautiful thing of all: nourish a new life.Yes, I'm talking about breasts. Angelina Jolie's breasts have been extensively discussed this week, more now that they are reportedly gone than when they were ........ Read more »

Does Loss of DNA Methylation and Hydroxymethylation in the Brain Lead to Loss of Memory?
5-methylcytosine (5-mC) and 5-hydroxymethycytosine (5-hmC) are two major epigenetic modifications of DNA. Dynamic changes in 5-mC and 5-hmC levels are tightly regulated and impact neural cell development, differentiation, and other biological functions. Deregulation of 5-mC and 5-hmC has also been implicated in various human diseases. However, whether 5-mC and 5-hmC are involved in aging-related neurodegenerative ...... Read more »

Hard at work against the hardening of arteries
by Patrick Bartosch in Beaker
Sanford-Burnham researchers identified a potential drug target to prevent the hardening of arteries in patients with atherosclerosis. The gene Dkk1 encodes a protein that plays a key role in increasing the population of connective-tissue cells during wound repair, but prolonged Dkk1 signaling in cells lining blood vessels can lead to fibrosis and a stiffening of artery walls....

Why not use human material for medical research?
by Professor Gareth Sanger in NC3Rs Blog
Using human tissue in medical research throws up a number of different challenges. In our third 2012 NC3Rs 3Rs Prize post, Professor Gareth Sanger from Queen Mary, University of London, discusses how tissue removed from the stomach and intestine can actually help overcome some of these challenges. Is this a viable alternative to using animals for gastrointestinal research? Professor Sanger’s research suggests it could be.... Read more »

Good News or Bad News - Skin cancer and Alzheimer’s disease
by Usman Paracha in SayPeople
Main Point:
Researchers have found that the people, who develop skin cancer, may have less chances of developing Alzheimer’s disease in the older ages.
Published in:
Neurology
Study Further:
Alzheimer’s disease is a degenerative disorder that affects the brain and causes dementia, especially late in life.
In this new study, researchers worked on 1,102 volunteers with an average age of 79. They were studied for about 3.7 years. In the beginning of the study, 109 peop........ Read more »

"Fool Me Twice, Shame on ME," Says Sea Slug
by Elizabeth Preston in Inkfish
"Simple" is often a compliment in the human world, used to describe low-fuss dinners or closet solutions. When scientists use "simple" to describe an animal, they mean something more like, "That sac of goo has no business acting clever." An especially simple creature—a sea slug—recently demonstrated that despite its humble resources, it can learn from experience and form new hunting strategies. Smaller goo sacs, beware.
Despite its squishy stature, the sea slug Pleurobranchaea calif........ Read more »
