Physicists Figure Out How To Take Photographs In Near-Total Darkness
Tens of thousands of photons go into making up each pixel in your standard cat photo. That’s because existing cameras — even infrared night-vision ones — rely on many, many photons of light to create an image. But now physicists have photographed in almost pitch blackness, where there on average is less than one photon…

Monster Machines: The World’s Strongest MRI Will Be Able To Pick Up A Tank
The stronger an MRI machine’s magnetic field is, the better image resolution and refresh rates it is able to achieve. While most medical-grade MRIs today top out between 1.5 and 3 Tesla, the unit measure of magnetic field strength, GE has recently constructed a unit with the whopping power of 7 Tesla. But that’s nothing…

Every Neuron In A Brain Recorded In 3D On A Millisecond Timescale
To learn how the whole brain works, it doesn’t do to just record from one neuron — you want to know what every single neuron is doing every millisecond. Now scientists have invented a technique that can actually capture the 3D activity of an entire brain milliseconds at the time — possibly the most complete…

Monitoring Gene Activity Across Thousands Of Cells Sure Is Pretty
Scientists have developed a new technique that allows them to visualise gene activity in thousands of cell, simultaneously. That will allow them to understand how our cells function like never before — and it looks damn pretty too.
