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....

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 »

Discover Discovery Learning with Guidance

For the penultimate round of the TV show The Apprentice, the competing entrepreneurs must face a series of interviews with a crack team of hardened executives.

To Predict a Bird’s Song, Head Out to Space
by Andrew Porterfield in United Academics
Any given species of bird probably has a variety of different songs. Most bird studies track individual birds in their own habitats, and then make more or less one-by-one comparisons—a bird in a forest will sound different from the same species in a city. An international team has taken these studies one step further—by making a giant leap into space.... Read more »

Did group selection play a role in the evolution of plasmid endosymbiosis?
by Eric Bolo in Evolutionary Games Group
Bacterial plasmids are nucleotide sequences floating in the cytoplasm of bacteria. These molecules replicate independently from the main chromosomal DNA and are not essential to the survival or replication of their host. Plasmids are thought to be part of the bacterial domain’s mobilome (for overview, see Siefert, 2009), a sort of genetic commonwealth which most, […]... Read more »
