Wolfgang Amadeus Mozart is considered by many to be the greatest composer ever. And his 27 piano concertos may be his finest work. But Mozart had a formula for the 27 and he used it over and over again, so they were all similar in certain ways. A little music theory plus, a very special treat at the end.

1. Tech Times seeks to inject some science into police violence discussions and uses our work to do it. In the ongoing debate over gun ownership, a lot of papers are produced but not all of them make sense. "Virtual lives lost" is one such metric. Like virtual water, virtual money, and virtual emissions, pretend assets can't be utilized. If someone dies young, is is correct to assume they will live to be 80? Not really, which is why average life expectancy is a flawed notion.

Vical continues to push its VCL-HB01  herpes vaccine through development. Larry Smith, Ph.D., the senior VP of Research, answers some questions about where things stand now and what to expect in the near future. 

In the media, it's not uncommon to see the words "bacteria" and "virus" used interchangeably. However, they are far from the same thing. In response to a recent Post article that made this microbiological faux pas, we feel the need to clarify and explain the differences.

When one stops to consider the particular circumstances of a 104-year-old's recent decision to end his life, it's difficult for many who sympathize with his plight not to see the judgment as anything but reasonable. However, that's just one view. What's yours – in this case, and pertaining to the topic of voluntary euthanasia in general? We like to hear from you.

Walmart apparently has some big plans for its pharmacies and it will involve you. A whistleblower document from the company reveals what steps it will take to (wrongly) address the overuse of painkillers. You will be graded on your probability of misusing not just opiate drugs, but also sedatives and stimulants. Since when does Walmart tell our doctors what they can or cannot give to their patients? 

If integrative medicine wants to be taken seriously, then they need to provide data obtained from actual scientific studies. There is no complementary science.  

Only 15% of new homes utilized solar panels. The California Energy Commission now requires all homes to have them because they're good for the environment and they "save you money." But as you may have guessed, there's more to the decision than that.

The recent self-death by 104-year old scientist David Goodall brings to the fore a key question: Whether to deem deterioration from advanced aging – beyond having an incurable disease – as another reasonable consideration for euthanasia.
