Video Tip of the Week: TrioVis for family genome data sets
I’m always interested in new strategies to visualize data. So when I saw discussion about a tool to help analyze family genomic data, I went to have a look. TrioVis is a new software tool that offers nice visualization and filtering strategies for exploring parent and child trio data sets. These data sets will become [...]... Read more »

The Challenges of Pain Management in Primary Care
by Kim Kristiansen in Picture of Pain
A new study reveals that European primary care physicians find dealing with chronic pain patients to be challenging, but at the same time rate it as a low priority area. Across Europe 84% of the 1308 primary care physicians who participated in the study found, that their initial training in chronic pain management was not comprehensive.... Read more »

Gun-Use Research Gets Long-Overdue Boost
by Kate Blanchfield in United Academics
Too many days in the United States, a young man enters a public space, heavily armed. Shots are fired. Sometimes the killer takes his own life. Over the next few days, television news, newspapers and websites carry a photograph of the alleged gunman (they’re usually male), with a disturbing expression on his face and an accompanying that discusses his possible mental instability....

Homing and Re-homing Fido: How many newly-adopted pets are still kept six months later?
by CAPB in Companion Animal Psychology Blog
When people adopt a new pet, why do some of them re-home the pet before six months is up? And how many actually still have the pet in the home? These are the questions asked in a new survey for the American Humane Association, funded by PetSmart.Every year in the US, 3 to 4 million homeless dogs and cats are euthanized. Understanding how many pets are not kept, and the reasons why, is essential to finding ways to solve the problem of pet overpopulation. The problem is not unique to the US......... Read more »

A Big Plant In A Little Package
by Mark Lasbury in As Many Exceptions As Rules
Phytoremediation is a big idea to help detoxify the environment. One great candidate for phytoremediation efforts is the smallest flowering plant on Earth, Wolffia globosa. This plant has no roots, no leaves, no stem, and no problem sequestering cadmium and arsenic. The entire plant is about the size of a grain of salt, but may also turn out to be a more important food source than soybeans!... Read more »

Social Media Use Linked to Narcissism
by Anouk Vleugels in United Academics
According to a new study published by researchers at the University of Michigan, social media might just be the perfect way to express our narcissistic tendencies. “Among young adult college students, we found that those who scored higher in certain types of narcissism posted more often on Twitter,” said Panek, leading author. ”But among middle-aged adults from the general population, narcissists posted more frequent status updates on Facebook.”

Fatigue Causes Decline in Lower Extremity Biomechanics
by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field
Take Home Message: As the body fatigues there may be apparent compensatory strategies employed, however, lower extremity biomechanics deteriorate as fatigue becomes greater. This may have implications for injury prevention program implementation.
Lower extremity injuries (e.g., anterior cruciate ligament [ACL], ankle sprains) tend to occur later in games or practices when athletes may be fatigued; hence, fatigue may increase susceptibility to lower extremity injuries. However, there is only........ Read more »

Publication Bias - The Lit Whisperers
by Rogue Medic in Rogue Medic
The Lit Whisperers raise an important point about publication bias and the validity of published studies that show benefit from a drug company study of a treatment that still has patent exclusivity.[1]
There are many problems with science. Science will never be perfect, but only people who do not understand science claim that it should be perfect.
One of the problems with science is publication bias. A paper that has a positive results about a brand name drug is twice as likely to be publi........ Read more »

Sleep Effects of Orexin Receptor Drugs in Insomnia
by William Yates, M.D. in Brain Posts
In a previous post, I reviewed a recently clinical trial studying the effect of an orexin receptor blocking agent in the treatment of insomnia.Orexin appears to be a neurochemical involved in arousability and motor activity. Preliminary studies suggest the orexin receptor may provide a novel target for hypnotics in the treatment of insomnia.An important question in the effects of orexin is whether the hypnotic effect of orexin simulates the same sleep effects as seen by the more studied be........

Moths Wait until Bats Lock On, Then Jam Their Sonar

If you are a human reader, you've probably never seen your lunch put up an invisibility shield and perform an evasive maneuver just as you reached for it. But spare a thought for the bats. If your peanut-butter sandwich were anything like a tiger moth, you'd have a hard time finding a meal.
