This thing was not imagination,” he says, jabbing his index finger into the tablecloth. By Cuarón’s estimation, anyone surprised at the accuracy of his movie’s predictions was either uninformed or willfully ignorant about the way the world already was by 2006.’

Making muscles burn more fat and less glucose can increase exercise endurance, but could simultaneously cause diabetes, says a team of scientists from Baylor College of Medicine and other institutions.
Mouse muscles use glucose (carbohydrate) as fuel when the animals are awake and active and switch to fat (lipid) when they are asleep. The team discovered that disrupting this natural cycle may lead to diabetes but, surprisingly, can also enhance exercise endurance. The switch is controlled by a molecule called histone deacetylase 3, or HDAC3. This finding opens the possibility of selecting the right time to exercise for losing body fat but also raises the concern of using HDAC inhibitors as doping drugs for endurance exercise. The study appears in Nature Medicine.
“How the muscle uses glucose is regulated by its internal circadian clock that anticipates the level of its activity during the day and at night,” said senior author Dr. Zheng Sun, assistant professor of medicine—diabetes, endocrinology and metabolism, and of molecular and cellular biology at Baylor. “The circadian clock works by turning certain genes on and off as the 24-hour cycle progresses. HDAC3 is a key connection between the circadian clock and gene expression. Our previous work showed that HDAC3 helps the liver alternate between producing glucose and producing lipid. In this work, we studied how HDAC3 controls the use of different fuels in skeletal muscle.”
The year 2016 presented the world with a number of big surprises. Some positive, some negative, depending on whom one asks. Here at Medgadget, 2016 will be remembered for many amazing and pleasantly unexpected medical technology developments, many of which are foreshadowing cures for spinal cord injuries, effective treatment of diabetes, new ways to fight heart disease, and many other long sought-after medical solutions. Virtual and augmented reality systems, new imaging techniques, and innovative delivery approaches are changing the way doctors learn and take care of patients.
Looking back on the past year, we selected what we felt to be the most important, innovative, and surprising medical technology developments. They naturally fell into a few categories. Here we share with you Medgadget’s choices of Best Medical Technologies of 2016.
Could the so-called EmDrive be close to debuting for real, helping spacecraft travel through space and producing thrust without the help of propellant? One month after NASA’s exciting study on the drive that suggested it may work, Chinese researchers have just confirmed that they’ve been running some tests on their own version of the drive in low-Earth orbit, adding some intrigue to what some have called a modern-day “space race” with the U.S.
According to Digital Trends, the EmDrive was originally designed in 2001 by Roger Shawyer as a propulsion system that doesn’t rely on conventional means to operate. That means that it doesn’t make use of fuel to do its work, thus making spacecraft considerably lighter and easier to maneuver, while also potentially reducing costs. Another exciting aspect of the drive is its potential to push spacecraft to unusually high speeds – as Digital Trends described it, that could mean sending humans to the outer reaches of the solar system in mere months, instead of years.
