It sounds garish now, but ancient Peruvians were surprisingly adept at it, so adept that Incan "neurosurgeons" had twice the survival rate for the procedure than better equipped surgeons during the American Civil War centuries later.
Obviously there could be differences in when it was done, so it may be due to confounders that in Incan times the mortality rate was between 17 and 25 percent while during the Civil War it was between 46 and 56 percent.

2. The act or process of pretending; feigning.
3. An assumption or imitation of a particular appearance or form; counterfeit; sham.
Well, high-energy physics is all about simulations.
We have a theoretical model that predicts the outcome of the very energetic particle collisions we create in the core of our giant detectors, but we only have approximate descriptions of the inputs to the theoretical model, so we need simulations.
There is no rhyme or reason to the increases, half of states, from cultures as different as Vermont and North Dakota, saw large changes of over 30 percent. Suicide is the 10th-leading cause of death in the U.S., and rates have been climbing steadily for years. With 44,965 suicide deaths in 2016, half of them using a firearm, the CDC would like to know why.
Chronic HCV is a major public health problem in Canada with serious health effects leading to premature death. In 2013, about 252,000 Canadians were infected with HCV. People born between 1945 and 1975 have the highest rates of HCV, although an estimated 70% of this group have not been tested.
Short summary: This is a first paper in what they hope to be a long term study. It’s an interesting project, but it should not be used to predict what will happen to Earth in the future. Their research is at far too early a stage to do that. It makes many simplifying assumptions that do not apply to Earth as it is now. I am publishing this article because I've been contacted by several people who got scared by the news reports about this study thinking it means we are likely to go extinct. No, it does not mean that at all.
Trump Kim Summit: Expect Hollywood Filming! Grand Gestures! Real Progress! Civilian Space Program Uniting North & South Korea?
First, one thing we will get for sure is a Hollywood style production of the visit with good music too. Korean television has been devoted for many years to constant Hollywood style movies about Kim Jong Un, and they have got very good at it, high production values. Trump can expect Kim to do the meeting proud if their film makers are given a free hand as they have been for the meetings with Moon and with Pompeo. It’s not surprising, the North Koreans have been doing this for all of Kim Jong Un’s activities for years now - he goes to talk to workers in a factory in NK and it becomes a Hollywood type experience for the viewers.
This actual science appeared in the medical melodrama "Grey's Anatomy." The episode “Hold Back the River” featured the show’s doctors using focused sound waves to treat a hypothalamic hamartoma in a young boy, and it is being tested in a clinical trial at UVA.

Will First Mars Astronauts Have To Stay In Orbit - Tele-operating Sterile Surface Rovers - To Prevent Colliding Biospheres?
Many astrobiologists think there is a decent chance that there’s native life on Mars, although probably only microbial. If so, astronauts landing on Mars might become part of a collision of two biospheres, mixing some of the microbes from Earth with some from Mars. What happens if you do that? Could the biospheres harm each other, or will both types of microbes get on wonderfully well together? Would we notice problems on Mars, or only once they get back? Nobody can say for sure at present.
We're not going to wean human babies on a starvation diet and then expect them to do it for 110 years. They will discover In-N-Out Burgers somewhere along the way.
But while aging is going to remain the biggest risk factor for diseases like cancer, cardiovascular diseases, type II diabetes and Alzheimer's disease, obesity will soon overtake smoking as the number two. What can bridge the gap between humans and the flies, worms, fish and mice that have benefited from a lifetime diet?
It probably happens every minute of the day: A little girl demands to see the photo her parent has just taken of her. Today, thanks to smartphones and other digital cameras, we can see snapshots immediately, whether we want to or not.
But in 1944 when 3-year-old Jennifer Land asked to see the family vacation photo that her dad had just taken, the technology didn’t exist.
Though it would seem that only global cooperation can solve global environmental problems, globalization in its current form works against sustainability. WTO-style capital liberalization causes investment to shift quickly to the site of highest returns, irrespective of national borders. To a far greater extent than in the past, fear of disinvestment causes CEOs to strive for maximum short-term profits.
It doesn’t take a genius to understand that corporate short-termism is incompatible with long-term sustainability.
