Is Ego-Depletion a Replicable Effect?
Abstract It has been a common practice in social psychology to publish only significant results. As a result, success rates in the published literature do not provide empirical evidence for the existence of a phenomenon. A recent meta-analysis suggested that ego-depletion is a much weaker effect than the published…

Just A New Fractal Detail In The Big Picture (2015)
When the central heating takes effect I'll get up and make myself some tea and porridge to which I'll add some nuts and fruit. I'll switch on The World Service to hear the news, and then make a few phone calls about damp-proofing. And I'll probably plant the daffodil bulbs for Spring (it says on the packet they should…

Hubble captures vivid auroras in Jupiter’s atmosphere
Astronomers are using the NASA/ESA Hubble Space Telescope to study auroras — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the Solar System, Jupiter. This observation programme is supported by measurements made by NASA’s Juno spacecraft, currently on its way to Jupiter.

Jupiter Awaits Arrival of Juno
In preparation for the imminent arrival of NASA’s Juno spacecraft, astronomers have used ESO’s Very Large Telescope to obtain spectacular new infrared images of Jupiter. They are part of a campaign to create high-resolution maps of the giant planet. These observations will inform the work to be undertaken by Juno over…

What are “actual pictures” of atoms actually pictures of?
Physicist: Actual pictures of atoms aren’t actually pictures at all. There are a few good rules of thumb in physics. Among the best is: light acts like you’d expect on scales well abov…

Nuclear Power in China
China has become largely self-sufficient in reactor design and construction, as well as other aspects of the nuclear fuel cycle. The strong impetus for nuclear power in China is increasingly due to air pollution from coal-fired plants.

To approximate 52! by hand, compute 54! and divide by 3000
Some time ago I gave a talk in which I showed that something unexpected happened with a deck of playing cards. I had some volunteers try it, and while they did so I talked about just how many orderings there are for 52 cards. I computed (an approximation to) $52!$ (52 factorial) by hand. It's not so hard - you just…
