Dementia rates are dropping sharply: Study

Dementia rates are dropping among people older than 65.

There is hope for people who are worried about dementia.The Lancet has published recent discoveries that reveal dementia rates among people older than 65 are dropping.  Alzheimer researchers are excited about the possibility that every successive generation will not face the same risk of dementia as commonly believed from previous studies.

Will the rise of the pharmacy clinic disrupt the American health care system?

Pharmacy clinics provide the sort of basic care that most people need at a fraction of the cost.

The U.S. is getting fatter, older, and in need of more medical care.  There’s a huge opportunity for companies to really disrupt the American health care system because of this. The opportunity waits in plain sight at your local pharmacy, and some companies like Walgreens and CVS have taken notice and hope that you will too.

More companies offering workers unlimited time off

Engaged employees who had a lot of flextime at work had a 44 percent higher level of well-being than disengaged employees with very little to no flextime.

Talent Plus, like many companies across the Midlands,  finds summer an ideal time for employees to take off.  But employees at the Lincoln-based human resources firm don’t go through the formal process of accruing their leave. They check with their manager, coordinate with others in their department and take time off from a limitless bank of days and hours. In short, co-chairman Kimberly Rath said, no questions asked, as long as the work gets done.

Scientists invent injectable oxygen that will let you live without breathing

You may soon breathe underwater by injecting oxygen into your bloodstream.

Researchers at Boston Children’s Hospital have designed microparticles that can be injected into your bloodstream to quickly oxygenate your body. Even if you can’t/aren’t breathing. And it can keep people alive for 15 to 30 minutes. It’s one of the best medical breakthroughs in recent years, and one that could save millions of lives every year.

There has already been success by researchers in growing tracheas, bladders, and body parts like noses on scaffolds using stem cells. Why not try to develop something more complex, like a heart or lungs? Dr. Harald Ott is a surgeon and researcher at Boston’s Massachusetts General Hospital who has been working on this very question.

Science might have gotten it wrong. Now what?

The debate started in late 2011, when Chen-Yu Zhang’s team f found bits of rice RNA floating in the bloodstreams of Chinese men and women.

Last week, freelance journalist Virginia Hughes wrote about a scientific paper that was published in the elite journal Nature in 1995.  The findings of said paper were called into question by several other papers in different journals within a couple of years. As of today, nearly two decades since the original came out, nobody has replicated it. And yet, it’s still sitting there in the literature, still influencing others. It’s been cited nearly 1,000 times.

Growth of healthcare jobs in America: Graph

Here’s what an astonishing graph (via Brookings) says. Job growth in America’s non-health-care economy has been dreadful during the last ten years. Just 2.1 percent total — or barely 0.2 percent per year. (Yes, that’s point-two percent annual growth.) In that time, the U.S. health care sector has grown more than ten-times faster than the rest of the economy, adding 2.6 million jobs.

Contact lenses that give you telescopic vision

A prototype contact lens-and-glasses system that lets you zoom in on something to 2.8X magnification.

New contact lenses have been created that when paired with special spectacles, bestow telescopic vision on their wearers.  The contact-lens-and-spectacles combination magnifies scene details by 2.8 times.

Italian neuroscientist believes human head transplant surgery is possible

Researcher thinks human head transplant surgery is finally possible.

A neuroscientist in Italy believes he’s figured out how to do a full human head transplant. Or body transplant, depending on your perspective. Dr. Sergio Canavero of the University of Turin explains in a recent paper how the procedure would work, describing how a “clean cut” with an “ultra-sharp blade” could leave the two severed spinal cords in the condition to be re-attached. “It is my contention that the technology only now exists for such linkage,” writes the researcher.

Top 3 challenges of longevity

In developed nations people are living longer.  There are increases in life expectancy at birth ranging from 2.7 years in Greece to 5.1 years in Ireland, between 1990 and 2010.This longevity rise has been attributed to improving health factors, better lifestyles and medical advances. This is giving us reasons to celebrate, but what are the challenges of living longer?
