A nanoscale black hole, really?
A black hole – one of the most fearsome and powerful objects in the universe – as big as a few atoms, in a lab? Sounds unlikely; but it’s not weird science. Well, perhaps there is a little exaggeration, but researchers at Harvard University (Massachusetts, USA) have created the miniest of black hole like behavior [...]

Quantum physics (like life?) in higher temperature entanglement
It’s been ‘common knowledge’ in the physics community that experiments with quantum entanglement, that weird state where two objects share the same existence, can only take place at extremely low temperatures – roughly a maximum of 4 degrees Kelvin above absolute zero. (That’s about -457F or –272C.) It therefore gives physicists something like what Americans [...]

Quantum chemistry – a new world
Here’s the story in a nutshell: Scientists have long known how to control the internal states of molecules, such as their rotational and vibrational energy levels. In addition, the field of quantum chemistry has existed for decades to study the effects of the quantum behavior of electrons and nuclei—constituents of molecules. But until now scientists [...]

The absolutely coolest thermometer
There’s nothing colder than absolute zero. In various scales that’s (in degrees): 0 Kelvin, -273.15 Celsius, -459.57 Fahrenheit. It’s so cold that the rest of the universe would have to reach that temperature to attain it, which is called absolute entropy, or the death of everything. So it’s not even theoretically possible to reach absolute [...]
