(HealthDay)—Get up off of the couch: Sitting too much may kill you even if you exercise regularly.

If you sit for six hours a day or more, your risk of dying early jumps 19 percent, compared with people who sit fewer than three hours, an American Cancer Society study suggests.

And, the study authors added, sitting may kill you in 14 ways, including: cancer; heart disease; stroke; diabetes; kidney disease; suicide; chronic obstructive pulmonary disease (COPD); lung disease; liver disease; peptic ulcer and other digestive disease; Parkinson’s disease; Alzheimer’s disease; nervous disorders; and musculoskeletal disorders.

Faraday Future, the fledgling Tesla competitor working to build a $300,000 electric SUV, has been thrown a financial lifeline.

Evergrande Health, a division of a large Hong Kong conglomerate, has committed to invest $2 billion to keep alive the all-electric luxury SUV project, according to a report in TechCrunch.

Faraday Future showed off its ultra-futuristic—and ultra expensive—FF91 electric SUV at the 2017 CES show, but has struggled to bring the car to market.

Babylon Health’s AI-powered robo-docs could save insurers and governments billions.

Ali Parsa’s AI-powered robo-docs could save insurers and governments billions. He’s already transformed a swathe of Britain’s socialized healthcare system, now he’s bringing it to the United States.

Recorded at “Contra Krugman: The Economic Myths of the 2016 Election”: the Mises Circle at Seattle’s historic Town Hall, on 21 May 2016.

Presidential candidates promise everything from living wages to free health care and college. Proposals about how to run whole segments of the economy are made with a straight face. The most tired and hackneyed ideas about income equality, corporate greed, creating jobs, and paying one’s fair share of taxes are trotted out. And millions of voters apparently believe it all, falling for the same promises of free stuff and prosperity from Washington.

Article (2017) about oxygen depletion. “There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. Although the magnitude of this decrease appears small compared to the amount of oxygen in the atmosphere, it is difficult to predict how this process may evolve, due to the brevity of the collected records. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health. We discuss the impact that global deoxygenation, over hundreds of generations, might have on human physiology. Exploring the changes between different native high-altitude populations provides a paradigm of how humans might tolerate worsening hypoxia over time. Using this model of atmospheric change, we predict that humans may continue to survive in an unprotected atmosphere for ~3600 years. Accordingly, without dramatic changes to the way in which we interact with our planet, humans may lose their dominance on Earth during the next few millennia.”

Deep in the rocky earth, in the liquid-filled cracks created by fracking, lives a community of highly interactive microbes—one that could at once have serious implications for energy companies, human health and scientists investigating the potential for life on Mars.

New research has uncovered the genetic details of microbes found in fracking wells. Not only do a wide array of bacteria and viruses thrive in these crevices created by hydraulic fracturing—they also have the power to produce methane, according to a study led by scientists at The Ohio State University and published in the journal Proceedings of the National Academy of Sciences.

That means it’s possible that the tiny life forms could create more energy—and from a different source—than the fracking companies are going after in the first place.

An international team of researchers have developed a low-cost sensor made from semiconducting plastic that can be used to diagnose or monitor a wide range of health conditions, such as surgical complications or neurodegenerative diseases.

The sensor can measure the amount of critical metabolites, such as lactate or glucose, that are present in sweat, tears, saliva or blood, and, when incorporated into a diagnostic device, could allow health conditions to be monitored quickly, cheaply and accurately. The new device has a far simpler design than existing sensors, and opens up a wide range of new possibilities for health monitoring down to the cellular level. The results are reported in the journal Science Advances.

The device was developed by a team led by the University of Cambridge and King Abdullah University of Science and Technology (KAUST) in Saudi Arabia. Semiconducting plastics such as those used in the current work are being developed for use in solar cells and flexible electronics, but have not yet seen widespread use in biological applications.

A team of researchers from ETH Zurich and the University of Basel in Switzerland and Institut Universitaire de Technologie in France has that found that embryonic kidney cells engineered to produce insulin when exposed to caffeine were able to reduce glucose levels in mouse models. In their paper published in the journal Nature, the group describes their efforts and how well it worked in the mouse models.

People with diabetes suffer from higher than normal levels of glucose in the blood, which can lead to a host of health problems. Current treatments include drugs that make cells more sensitive to insulin, or injection of insulin to make more of it available to cells that need it. In this new effort, the researchers have developed a new way to get more insulin into the body when it is needed most.

Instead of adding insulin externally, the researchers engineered embryonic kidney cells to produce it—but only when they were exposed to caffeine. The team chose caffeine because it has been so extensively studied and because the majority of people consume caffeinated beverages, such as coffee and soft drinks. They point out that caffeine is also a substance that appears very rarely in other foods, making its ingestion easy to regulate. The engineered cells were covered with a material that protected them from the immune system and were then put into a device that was implanted into the abdomens of mice that had been engineered to have diabetes. The researchers note that glucose levels tend to spike after people (and mice) eat sugar or food material that the body converts to sucrose. Thus, the optimal time for giving the mice caffeine would be after eating.

Only 35 per cent of five- to 17-year-olds and 62 per cent of children ages 3 and 4 are getting the recommended physical-activity levels for their age group (Editor’s note: around 60 minutes of moderate-to-vigorous physical activity daily, including vigorous-intensity activity on at least 3 days per week) and that this may be having an impact on the health of their brains.
