Girls with autism display less repetitive and restricted behavior than boys do, according to a study by researchers at the Stanford University School of Medicine.

The study also found that brain differences between boys and girls with autism help explain this discrepancy.

The study, which will be published online Sept. 3 in Molecular Autism, gives the best evidence to date that boys and girls exhibit the developmental disorder differently.

Using an inexpensive drug for every hip or knee replacement since 2013 has helped St. Michael's Hospital reduce its number of red blood cell transfusions performed during these surgeries by more than 40 per cent without negatively affecting patients, according to new research.

The drug tranexamic acid, known as TXA, prevents excessive blood loss during surgeries.

TXA had been shown to be effective in orthopedic, trauma and cardiac patients but less than half of eligible patients at St. Michael's received this drug because of a previous province-wide shortage. The drug was given only to patients at high risk of requiring a blood transfusion.

A few years ago, I couldn’t read an energy bill beyond the charge levied. I couldn’t tell you how energy was measured, or ultimately how its use related to making my life better or worse, let alone how it affected broader society and the planet.

I resolved to change this. I studied energy and sustainability at university, and have gone on to teach there. Throughout this time my wife and I have made many changes to how we use energy at home. Yet when we decided to take a closer look into our electricity bill, we were surprised by what we found.

I was at the ICNFP 2015 Conference, spending two nights to prepare updated versions of two posters following an idea that I had on August 22 just before taking the plane for Crete (the possible space-time contradiction between the preonic vacuum and the macroscopic world, leading to Quantum Mechanics for standard matter), when an important result was posted to arXiv.org .

The scientists behind the BICEP2 (Background Imaging of Cosmic Extragalactic Polarization) telescope, last year made an extraordinary claim that they had detected gravitational waves, which are ripples in space-time. Initially hailed as the most groundbreaking discovery of the century, it later proved a false alarm: the signal was merely galactic dust.

So are we likely to ever find gravitational waves? And would they really provide irrefutable evidence for the Big Bang? Here are five common myths and misconceptions about gravitational waves.

We want drugs to get better and we don’t want them to be just for the rich. Health care, in much of modern America, has become a right rather than a luxury so a country that is fine with overpaying for a phone is less inclined to have gaps in health care quality.

People want Apple and Samsung to make money so the companies are motivated to create the next great phone. If Apple is the most highly-valued company in the U.S., they earned it and if you want their new iPhone 6s first, you pay the price, even if the new features are negligible.

The existence of parallel universes may seem like something cooked up by science fiction writers, with little relevance to modern theoretical physics.

But the idea that we live in a “multiverse” made up of an infinite number of parallel universes has long been considered a scientific possibility – although it is still a matter of vigorous debate among physicists. The race is now on to find a way to test the theory, including searching the sky for signs of collisions with other universes.

The realization that everything would be okay regarding the obesity epidemic occurred to me in a doughnut shop. It was the last week of my employment as a weight loss doctor and for years, my clinic had been a junk food free zone. This was not because I set rules based on a notion that junk food is bad for a person. I didn't and I don't really have much worry about sugary snacks. It just happened as a sort of accidental byproduct of what we were doing. If you talk about diet rules all day and see how hard the patients are working to eat better, it just feels wrong to have a big box of doughnuts in the break-room...or powdered sugar on your slacks.

Since the 1980s, flagship comic-book superhero movie franchises – from DC’s Superman to Marvel’s Iron Man – have seen some major movie studio investments and, more often than not, blockbuster returns.

But significant changes in the superhero mythos in our culture indicate that their future seems bleak.

Universal Studios leads the year’s movie profits without a single superhero movie. Meanwhile, the latest Fantastic Four reboot has failed terribly.

The title of this post is also the title of a self-published book by George Triantaphyllou, a greek physicist whom I met two weeks ago in Kolimbari, when we attended the ICNFP 2015 conference. I had met George at the same conference three years before, and this year we had some time to chat during a nice excursion in a botanical garden near Chania and at the conference dinner. As he was kind enough to offer me a copy of his book, I thought I would relate about it here today.
