Nanoclusters break superconductivity record
Wow! Every now and again a paper on the arxiv leaps out at you and today there’s work from Indiana University in Bloomington that has got my eyeballs on stalks. Get this: a team led by Martin Jarrold is claiming to have found evidence of superconductivity in aluminium nanoclusters at 200 K . Yep, 200…

Global warming: we have 10 years to avoid catastrophe
The arxiv isn’t usually the place where climate scientists make predictions about global warming but yesterday, they made an exception. A group led by James Hansen, one of the world’s leading climate scientists who works at NASA’s Goddard Institute for Space Sciences, warned that global warming is having much worse effects on Earth’s climate than…

A survey of quantum programming languages
It cannot be long before somebody breathes life into a useful quantum computer. And when that happens, an entirely new breed of keyboard monkey will be born: the quantum computer programmer. This strange animal will have to work with the weird and wonderful tools of the quantum world, such as superposition of quantum bits, entanglement,…

Criticality and the brain
Our understanding of how various parts of brain function is advancing at breakneck speed and yet we are as far away as ever from an overarching “theory of the brain” that attempts to encompass these discoveries. Such a theory would unite disparate discoveries in brain science under a unifying theme. Now Dante Chialvo from Northwestern…

The hunt for superheavy elements
The heaviest elements are a shy, retiring bunch. No sooner are they created than they disappear in a puff of smoke. The heaviest, ununoctium, has an atomic number of 118 and an atomic weight of 294. The Russians made a single atom of the stuff back in 2002 only to discover that it hung around…

Qutrit breakthrough brings quantum computers closer
The folks playing with quantum computers have been claiming for years that their gadgets will one day make today’s supercomputers look like quivering lumps of jelly. But so far, their computers have yet to match the calculating prowess of a 10-year old with ADHD. The most exciting work so far has been on universal quantum…
