First Tidally Locked Super-Earth Exoplanet Confirmed

Posted by in categories: physics, space

An international team of astronomers and astrophysicists has confirmed the first known observance of a tidally locked super-Earth exoplanet. In their paper published in The Astrophysical Journal, the group describes the unique approach they took to confirm that the exoplanet LHS3844b is tidally locked and what the finding suggests about other planets in the galaxy.

Prior research has led astronomers to believe that some exoplanets are tidally locked, with one side that always faces the star they revolve around, but they have been unable until now to prove it. In this new effort, the research team picked a likely candidate and used a unique approach to study its attributes to ascertain its motion.

Prior research has shown that several moons in our solar system, including the one circling Earth, are tidally locked, always facing the planet they orbit. In this situation, their rotation period matches their orbital period—the result is a moon that always shows the same side to its planet. For this reason, the Earth’s moon has what has commonly been described as a “dark side”—the side we never see. Tidal locking is due to gravitational forces between a moon and its planet—or a planet and its star.

Marshall Brain: We’re approaching humanity’s make or break period

Posted by in categories: ethics, robotics/AI

Marshal Brain’s 2003 book Manna was quite ahead of its time in foreseeing that eventually, one way or another, we will have to confront and address the phenomenon of technological unemployment. In addition, Marshall is a passionate brainiac with a jovial personality, impressive background and a unique perspective. And so I was very happy to meet him in person for an exclusive interview. [Special thanks to David Wood without whose introduction this interview may not have happened!]

During our 82 min conversation with Marshall Brain we cover a variety of interesting topics such as: his books The Second Intelligent Species and Manna; AI as the end game for humanity; using cockroaches as a metaphor; logic and ethics; simulating the human brain; the importance of language and visual processing for the creating of AI; marrying off Siri to Watson; technological unemployment, social welfare and perpetual vacation; capitalism, socialism and the need for systemic change

As always you can listen to or download the audio file above or scroll down and watch the video interview in full. To show your support you can write a review on iTunes, make a direct donation or become a patron on Patreon.

Intermittent Fasting Linked to Vastly Increased Chance of Heart Attack and Stroke

Posted by in categories: biotech/medical, health

This regimented approach to dieting has helped many people achieve the discipline they need to lose weight, and some research has shown that it can provide a myriad of health benefits, including improved blood pressure.

But a new yet-to-be-published study, presented this week at a meeting of the American Heart Association, suggests that intermittent fasting could have serious consequences for your cardiovascular health.

In an analysis of over 20,000 US adults, the study found that those who eat in just an eight hour window or less per day — thereby fasting for at least 16 hours — had a 91 percent higher chance of dying from heart disease.
