Yoga and Meditation May Lead to an Inflated Ego

If you’ve been exasperated for years by that one self-righteous, yoga-obsessed friend, take note: Regular yoga practitioners experience inflated egos after a session of yoga or meditation, according to a forthcoming study in the journal Psychological Science.

Researchers found that yoga and meditation both increase "self-enhancement," or the tendency for people to attach importance to their own actions. In the first phase of the two-part study, researchers in Germany and England measured self-enhancement by recruiting 93 yoga students and having them respond to questionnaires over the course of 15 weeks, Quartz reports. Each assessment was designed to measure three outcomes: superiority, communal narcissism, and self-esteem. In the second phase, the researchers asked 162 meditation students to answer the same questionnaires over four weeks.

Participants showed significantly higher self-enhancement in the hour just after their practices. After yoga or meditation, participants were more likely to say that statements like "I am the most helpful person I know" and "I have a very positive influence on others" describe them.

At its Hindu and Buddhist roots, yoga is focused on quieting the ego and conquering the self. The findings seem to support what some critics of Western-style yoga suspect—that the practice is no longer true to its South Asian heritage.

It might not be all bad, though. Self-enhancement tends to correlate with higher levels of subjective well-being, at least in the short term. People prone to self-enhancement report feeling happier than the average person. However, they’re also more likely to exhibit social behaviors (like bragging or condescending) that are detrimental in the long term.

So if you think your yoga-loving friends are a little holier than thou, you may be right. But it might be because their yoga class isn’t deflating their egos like yogis say it should.

The World's First Full-Color 3D X-Rays Have Arrived

The days of drab black-and-white, 2D X-rays may finally be over. Now, if you want to see what your broken ankle looks like in all its full-color, 3D glory, you can do so thanks to new body-scanning technology. The machine, spotted by BGR, comes courtesy of New Zealand-based manufacturer MARS Bioimaging.

It’s called the MARS large bore spectral scanner, and it uses spectral molecular imaging (SMI) to produce images that are fully colorized and in 3D. While visually appealing, the technology isn’t just about aesthetics—it could help doctors identify issues more accurately and provide better care.

Its pixel detectors, called “Medipix” chips, allow the machine to identify colors and distinguish between materials that look the same on regular CT scans, like calcium, iodine, and gold, Buzzfeed reports. Bone, fat, and water are also differentiated by color, and it can detect details as small as a strand of hair.

“It gives you a lot more information, and that’s very useful for medical imaging. It enables you to do a lot of diagnosis you can’t do otherwise,” Phil Butler, the founder/CEO of MARS Bioimaging and a physicist at the University of Canterbury, says in a video. “When you [have] a black-and-white camera photographing a tree with its leaves, you can’t tell whether the leaves are healthy or not. But if you’ve got a color camera, you can see whether they’re healthy leaves or diseased.”

The images are even more impressive in motion. This rotating image of an ankle shows "lipid-like" materials (like cartilage and skin) in beige, and soft tissue and muscle in red.

The technology took roughly a decade to develop. However, MARS is still working on scaling up production, so it may be some time before the machine is available commercially.

Although it was discovered in 1906, Alzheimer’s disease didn’t receive significant research attention until the 1970s. In 1984, scientists identified the plaque-like buildup of amyloid beta proteins in brain tissue that causes nerve damage and can lead to symptoms like memory loss, personality changes, and physical debility.

Now, researchers are learning why amyloid beta tends to collect in brain tissue like barnacles on a ship. It might not be rallying expressly to cause damage, but to protect the brain from another invader: the herpes simplex virus.

As The Atlantic recently noted, a number of studies have strengthened the notion that amyloid beta activity is working in response to herpes, the virus that travels along nerve pathways and typically causes cold sores around the mouth (HSV-1) or genitals (HSV-2). In a study involving mice, those engineered to produce more amyloid beta were more resistant to the herpes virus than those who were not.

But when too much amyloid beta is produced to combat the virus, the proteins can affect the brain’s neurons. And while herpes tends to target specific pathways in the body that result in external sores, it’s possible that the virus might act differently in an older population that is susceptible to more widespread infection. Roughly half of adults under age 50 in the U.S. are infected with HSV-1 and 12 percent with HSV-2, which suggests that a large swath of the population could be vulnerable to Alzheimer's disease. Two other strains of the virus, HHV-6A and HHV-7, have also been found to be more common in the brains of deceased Alzheimer’s patients than in the general population.

More research will be needed to further understand the possible relationship between the two. If more findings support the theory, then it’s possible that antiviral drugs or vaccines targeting herpes might also reduce the chances of amyloid beta buildup.
