Trepanation: Sometimes You Needed A Hole In The Head - And Incans Were Really Good At It

Jun 10 2018 - 13:06
For thousands of years, trepanation--the act of scraping, cutting, or drilling an opening into the cranium--was practiced around the world, primarily to treat head trauma but also for headaches, seizures and mental illnesses. Sometimes it was even done to expel demons.

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.

Modeling Issues Or New Physics ? Surprises From Top Quark Kinematics Study

Jun 10 2018 - 07:06
Simulation, noun:
1. Imitation or enactment
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.

Anthony Bourdain Has Committed Suicide And CDC Says Media Should Be Careful About Reporting It

Jun 08 2018 - 11:06
Suicides have gone up in the United States since 1999, according to the CDC, but then state it is more than a mental health issue.

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.

Canadian Journal Advocates For Hepatitis C Screening Of All People Born 1945-1975

Jun 08 2018 - 11:06
One way to manage chronic hepatitis C virus (HCV) is to abandon existing guidelines and screen all people born between 1945 and 1975 for the disease, according to a new paper

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.

Debunked: World To End In One Of Three Horrible Scenarios In Mathematical Model By Adam Frank

Jun 04 2018 - 06:06

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.

MiniBoone Confirms Neutrino Anomaly

Jun 01 2018 - 08:06
Neutrinos, the most mysterious and fascinating of all elementary particles, continue to puzzle physicists. 20 years after the experimental verification of a long-debated effect whereby the three neutrino species can "oscillate", changing their nature by turning one into the other as they propagate in vacuum and in matter, the jury is still out to decide what really is the matter with them. And a new result by the MiniBoone collaboration is stirring waters once more.

Trump Kim Summit: Expect Hollywood Filming! Grand Gestures! Real Progress! Civilian Space Program Uniting North & South Korea?

May 30 2018 - 22:05

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.

Sue And Settle Environmental Attorneys Are Having A Harder Time At EPA

May 30 2018 - 14:05
The days when environmental litigation groups like Earthjustice and Farmworker Justice had friendly voices in EPA and the White House seem like two years in the past. Because they are two years in the past. Where once environmental groups could write entire documents for the White House to repost in the name of the U.S., now they cry foul if organizations like Heartland even have email exchanges with EPA.

Focused Ultrasound To Treat 'Giggling' Epilepsy - 'Grey's Anatomy' Shows Off Cutting Edge Science

May 30 2018 - 09:05
Epilepsy is no laughing matter - except for one rare form, caused by hypothalamic hamartomas, benign masses in the brain that can cause epilepsy symptoms, unintentional giggling seizures and even early puberty.

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?

May 26 2018 - 17:05

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.

Forget Caloric Restriction - Gene Switching May Be A Better Route To Healthier Aging

May 25 2018 - 16:05
There are numerous proponents of caloric restriction as a way to achieve longevity, and the belief has a kernel of truth - you don't often find obese centenarians - but what they leave out of the narrative is that these are mice, and they were weaned on a starvation diet.

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?

Polycyclic Aromatic Hydrocarbons - Chinese Epidemiologists Declare Your Barbecue Will Kill You

May 24 2018 - 07:05
The American Chemical Society is a not-for-profit organization chartered by the U.S. Congress. That doesn't keep their editors from lobbying against science and common sense, like when a team of authors in Environmental Science&Technology, funded by the National Natural Science Foundation of China, are allowed to terrify Americans by scaremongering the American barbecue grill the weekend before Memorial Day.

Brazil's Economic Peril Could Increase Avoidable Child Deaths

May 23 2018 - 08:05
Tax and spend politicians and their supporters have begun framing austerity in a negative way. Austerity - spending what you make, or even less so you have a reserve - is now regarded as a negative by people that believe taxes and more government lead to growth, even if those beliefs are what led to their economic collapse.

USA 29th In Healthcare Access From 2000-2016

May 23 2018 - 07:05
Worldwide healthcare access and quality improved remarkably from 2000-2016 but there are unsurprising disparities between wealthy and poor countries - and countries like the United States which showed high quality but varying levels of access before the federal government took control of medical access with the controversial Obamacare law passed by Democrats.

70 Years Ago, The Polaroid Camera Came To Market - And A Science Boom Followed

May 20 2018 - 09:05

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.

The Globalization Paradox

May 19 2018 - 20:05

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.

Piero Martin At TedX: An Eulogy Of The Error

May 19 2018 - 11:05
Living in Padova has its merits. I moved here since January 1st and am enjoying every bit of it. I used to live in Venice, my home town, and commute with Padova during weekdays, but a number of factors led me to decide on this move (not last the fact that I could afford to buy a spacious place close to my office in Padova, while in Venice I was confined to a rented apartment).
