Recent studies have shed a little more light on the state of gas in your body. Besides the obvious, gas bubbles play a role in cracking your knuckles and in decompression sickness after scuba diving. A 2013 study indicates that drugs that regulate nitric oxide generation for vasodilation have a tendency to increase the chances of decompression sickness. This means you might want to skip the Viagra if you plan on diving. In terms of joint manipulation, a study shows that despite the annoying soun........ Read more »

Angelina Jolie shocked us all with her decision to remove both her breasts in order to prevent breast cancer. Her breast cancer risk was calculated based on genetics and was 87%. Now it is 5%. I have to agree that this woman is brave! However, I think a very intense screening could have been done with very good results. There are several methods to detect breast cancer: (digital) mammography, tomosynthesis, breast MRI, ultrasound, positron emission tomography and even microwave imaging. Some wit........ Read more »

From 1550 to 1580, the period of cooling known as the Little Ice Age hit Ellesmere Island, in extreme northern Nunavut, Canada. As temperatures plunged, most of the island was swallowed by the advance of glaciers. The vegetation that had blanketed the terrain—mostly mosses and lichens—was buried under dozens of feet of ice.... Read more »

The Social Organism is a 20-page essay published by Herbert Spencer in 1860.

For this reason Spencer is usually [...]... Read more »

Imagine you and your partner are about to enjoy a meal together. They have obsessive compulsive disorder (OCD) and get incredibly anxious until they've completed a time-consuming sequence of checks and rituals involving their cutlery. Do you offer to help with the checks in the hope of assuaging their anxiety?
The process of helping an OCD patient in this way is called "accommodation" and though it may be motivated by compassion and empathy, the authors of a new paper say that it can be a bar........ Read more »

Parents pass on a unique genetic makeup to their children. Little Johnny is a blonde-haired, blue-eyed boy with a one-of-a-kind thumbprint all because it is encoded in the DNA provided by his parents. But did you know that the quality of the DNA you pass on to your children can be impacted by stressful events in your life such as disease, malnutrition, and old age, ultimately influencing the way your children’s bodies respond to stress? That is what a new study looking at the impact of pa........ Read more »

Dr Sirous Mobini and colleagues have recently published a integrative review of the literature investigating the treatment of anxiety using cognitive bias modification.
Cognitive theories of social anxiety indicate that negative biases in thinking play a key role in causing and maintaining social anxiety. On the basis of these cognitive theories, research has shown that individuals with social anxiety interpret ambiguous social situations in a negative (or less passive) manner.

Take Home Message: There is still no clear answer as to whether to use an autograft or allograft bone-patellar tendon-bone ACL reconstruction.
Patients and clinicians often need to consider what surgical options they prefer when undergoing anterior cruciate ligament (ACL) reconstruction. Many physicians and researchers have investigated the benefits of either an auto- or allo- bone-patellar tendon-bone graft, however, conclusive evidence as to which is the best option has yet to be determine........

People who bill their time in the form of an hourly wage, i.e. “billable hour”, develop a “money mindset”.

Advertisements bemoaning the evils of obesity, begging us to eat healthier and to exercise, surround us every day. Big corporations and governments alike have jumped on the anti-obesity bandwagon, crafting public service announcements aimed at correcting what is being framed as an epidemic. For many, these messages are likely generic reminders to strive for health, if they are noticed at all. But what about individuals with eating disorders?

Rewind to last night. It was bedtime. My infant daughter was screaming and struggling in my lap while I tried to rock her to sleep. She pulled and twisted the skin on my face. She sunk her tiny teeth into my shoulder and chest. Exasperated, I rose from the rocker and started pacing around the nursery. Her tense little body instantly relaxed. Within ten seconds she was quiet and still. Within two minutes she was asleep.... Read more »

Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer, the team reports in the journal Advanced Materials this week....

Climbing is good. It allows for gaining access to habitats that would otherwise be unavailable. And while this access is important (otherwise, why climb in the first place?), equally important is not falling to a gruesome death. This means that your method of adhesion to the surface you are climbing needs to be effective. For example, on rough surfaces, friction pads and claws work rather well. Smooth surfaces and overhangs offer a bit more of a challenge. If you want to climb one of these surfa........ Read more »
