Brain-computer interfaces can replace bodily functions to a certain degree and now they can even compose music. At least in a sense.

Derived from an established brain-computer interface method which mainly serves to spell - more accurately - write, a team writing in PLOS One has shown how they developed a new application by which music can be composed just through the power of thought. All that is needed is a special cap which measures brain waves, composition software. Before you start to think you'll be the next Haydn, keep in mind it can't create musical knowledge.

This is a good example of a story that has morphed and changed as it gets passed from one paper to another. They all cite the same source, from the BBC but the reporters haven’t read the source. I think they just read each other. The science is actually rather interesting. But just about everything they say is the opposite of what the original story says. And actually the original paper suggests trying this at Long Valley in California rather than Yellowstone.

This is the original story on the BBC:

Back from vacations, I think I need to report a few random things before I get back into physics blogging. So I'll peruse the science20 article category aptly called "Random Thoughts" for this one occasion.
My summer vacations took place just after a week spent in Ecuador, where I gave 6 hours of lectures on LHC physics and statistics for data analysis to astrophysics PhD students. I did report about that and an eventful hike in the last post. Unfortunately, the first week of my alleged rest was mostly spent fixing a few documents that the European Commission expected to receive by August 31st. As a coordinator of a training network, I have indeed certain obligations that I cannot escape. 

The President has declared he is against the Estate tax, and he is not alone. For decades it has seemed punitive to levy a special tax on wealth people already paid taxes on just because the person who paid the taxes died. 

In North Dakota, President Trump said he would "protect small businesses and family farmers here in North Dakota and across the country by ending the death tax" and that would ease the "Tremendous burden for the family farmer, tremendous burden. We are not going to allow the death tax or the inheritance tax or the whatever-you-want-to-call-it to crush the American Dream.”

Even small tumors can be aggressive, according to a study in patients with early stage breast cancer presented at the ESMO 2017 Congress in Madrid.  They found that nearly one in four small tumors were aggressive and patients benefited from chemotherapy. Aggressive tumors could be identified by a 70-gene signature.

A while back I wrote my article "Can Giant Airships Slowly Accelerate to Orbit Over Several Days" . It lead to a lot of discussion and as usual whenever you discuss John Powell's ideas, there were physicists and aeroengineers saying it is impossible.

It may seem like olden days to millennials, but the late 1970s were a lot like today. America was divided due to an unpopular President, gas was expensive, the movie industry was at death's door ... and genetic engineering was a big concern.

The story that won't be told in the wake of Harvey's wrath is the incredible risk to the thousands upon thousands of items of physical evidence being stored in police departments and crime laboratories throughout Texas - especially in Houston.  Any damage to this evidence may derail the state's pursuit of justice.

The IAU famously decided that Pluto is not a planet any more, calling it a "dwarf planet" instead, along with Ceres. However, their definition works as well as it does only because of a historical accident of our solar system and the bodies we have discovered in it so far. There are good reasons for thinking it has a "use before" date too, as we'll see.
