When we asked “Do you think that there will be a cure for Alzheimers and other dementias by 2030?” only 8% of the 109 of you who responded were pessimistic.

Geoengineering has an image problem. Some proposed geoengineering projects, such as space mirrors or cloud seeding, seem like they come from the pages of a science fiction novel. Those who propose these projects are treated with belittling rhetoric. Other projects face a different type of imaging problem; the project’s proponents are accused of having vague or unspecified goals and timelines. Such projects are summarily dismissed as being idealistic, out of touch or nebulous.

One of the things that has always struck me as different — and not in a good way — in the United States compared to other Western countries is the way Americans think (and act) about crime, particularly their prison system. Recently, my colleagues Ken Taylor (Stanford) and John Perry (University of California-Riverside) have tackled the issue on their wonderful podcast, Philosophy Talk (which comes with an associated blog, the tagline of which is cogito, ergo blog), causing me to ponder some more disturbing thoughts about it.

Social media companies say consumers’ loss of privacy is just the cost of doing business. But what would happen if they actually had to bargain with users on equal footing?

Time for another thought experiment. Or, rather, a puzzle without a good answer yet.

  By around mid-century, many future followers predict the pace of technological progression in genetics, nanotechnology and artificial intelligence will become so fast that humans will undergo radical evolution. Advances that provide a forever youthful and healthy state of being could be realized.

In Khannea SunTzu remarkable new novel she’ll never write - The NeoProgressive’s New Deal - the leader character, Cassandra Assange (Daughter of Julian Assange, born in 2003), is the target of literal micro drone assassination attempts, a vicious media campaign and endless incapacitating litigation. She became a political activist like her father in the mid 2020s, and exemplified the new counter-cultural ideal. Militantly lesbian and technoprogressive she gave birth of a clone of her wife, and her wife gave birth to a clone of Cassandra in the late 2020s.

When I was a kid there was a series on Nostradamus narrated by an Orson Welles surrounded in cigar smoke and false gravitas. I had not seen The Man Who Saw Tomorrow for over 30 years, though thanks to the miracle of Youtube I was able to find it here.  Amazingly enough, I still remember Part 9 of the series in which the blue- turbaned, Islamic, 3rd antichrist allied with the Soviet Union plunges the world into thermonuclear war. I also remember the ending- scenes of budding flowers and sunshine signaling the rebirth of nature and humanity, a period of peace and prosperity to last 1,000 years.

Amid fretful resignation, we learn of the likely loss of the magnificent Kepler mission...which discovered as many as three thousand planets beyond our solar system.  (About 10% of them now confirmed.) Only two of the four gyro systems are still working, not enough for the probe to aim at more than a hundred thousand stars with uncanny accuracy, each day. While this will be a sad loss, the epoch introduced by the Kepler Mission bodes well for you understanding of the universe.

It's another blow for immersive virtual reality. University of California researchers have shown that even people with perfect eyesight navigate the world by relying on a lot more than what they see. Here's why VR won't really work until we go beyond visual cues and fancy treadmills.

What happens when religious institutions get to manage public funds, absorb secular hospitals, and put theology above medical science and individual patient conscience?

As reactions continue to race around the internet about Angelina Jolie’s double mastectomy and reconstructive surgery – the actual discussions, not the Monday-morning quarterbacking of her decision or the utterly vile “but what about her boobies” reaction from that particular subgroup of men who manage to amaze me by their continued ability to manage basic functions like breathing – I’ve been sent links.

I have been doing public outreach for science since I originally moved to Tennessee in 1996. It has been a fun ride, and I’m sure it will continue to be that way for many years to come. But two of the first things I learned when debating creationists and giving talks about the nature of science were: a) nastiness doesn’t get you anywhere; and b) just because you have reason and evidence on your side doesn’t mean you are going to carry the day.

California state Senator Leland Yee wants to stop people from being able to print out firearms with 3D printers. Like many other folks, Yee was startled by the work of Defense Distributed, a group working on designs for guns that can be produced by the 3D printers. A few months ago, Defense Distributed crafted a grip and lower receiver for an AR-15; more recently, they produced a fully-functional handgun.
