Still working to improve the world's understanding of quantum fluctuations and Boltzmann Brains.
http://arxiv.org/abs/1505.02780
Abstract: Many modern cosmological scenarios feature large volumes of spacetime in a de Sitter vacuum phase. Such models are said to be faced with a "Boltzmann Brain problem" - the overwhelming majority of observers with fixed local conditions are random fluctuations in the de Sitter vacuum, ...

Somehow when I imagine Boltzmann Brains popping into existence, instead all I can see are many Andy Albrecht heads appearing. Truly a strange universe...

After a long shutdown, the Large Hadron Collider sees collisions once again.

The Large Hadron Collider is back in the business of colliding particles.

Cool, counter-intuitive scientific results: exactly the ones you'd better be sure can be replicated.

Gladwell has made a career of cherry-picking the ideas that confound your expectations or common sense. Thanks for correcting one example of that deceptive and attractive publishing trick.

Science facts distribute along a scale of complexity that only partially intersects the capacities of common sense. There is a natural segregation occurring, then, between main attention populations, with a blind spot at the notion that should serve the progress of understanding to systematically cover theories that are less wrong than terse.

Illuminating a key step in the origin of complex life: transitional form between archaea and eukaryotes found.
http://nyti.ms/1Ihjlod
Scientists have discovered microbes that have many — but not all — of the features previously only found in eukaryotes.

Quantizing gravity is an important goal of contemporary physics, but after decades of effort it's proven to be an extremely tough nut to crack. So it's worth considering a very slight shift of emphasis. What if the right strategy is not “finding the right theory of gravity and quantizing it,” ...

That's not a very big improvement in uncertainty.

I do like that there's a "well, let's do an experiment" tone. If folks want to assert that "praying is real", their should be camps all over the place in competition to be the first to detect the transmissions. There should be some way to objectively find the mechanism of prayer. There should at least be some statistical benefit shown to exist from prayer, tabulated with error bars and the whole works.

Whether accidental, I felt the undertone of religious discussion in this video, also. Boris may have brought it to surface explicitly. It could even have been the intent of the producers to leave that issue sort of open. One can take from it that plenty of things exist beyond human perception and leave it at that. Or one can hopefully see that, through science, we join forces and stand on the shoulders of giants to see ever farther. It is through sharing useful information that our understanding of the world is enhanced. Imagination, alone, is not enough!

A seven-author paper, and not once did we cite any previous paper by ourselves. Is that a record?
http://arxiv.org/abs/1504.06632
Abstract: The Multi-scale Entanglement Renormalization Ansatz (MERA) is a tensor network that provides an efficient way of variationally estimating the ground state of a critical quantum system. The network geometry resembles a discretization of spatial slices of an AdS spacetime and "geodesics" ...

Physicist at Caltech. Master of time and space.
Introduction
I think about things that are smaller than atoms and/or bigger than galaxies.  Everything in between scares me.

Links on right will lead you to awesome things to read and think about.
