Holographic Camera Sees The Unseen

Researchers at Northwestern University have built a scattered light holographic camera that can see the unseen. The camera indirectly scatters coherent light onto hidden objects and detects any subsequent light scattering that arrives back into the camera. An image is then reconstructed using this returned scattered light to visualise hidden objects.

Cloaking Atoms

#290

MIT physicists have successfully demonstrated the Pauli exclusion principle, where a cloud of atoms that are ultra-cooled lose their ability to scatter light and start to become less visible.

First Synthetic Fuelled Flight

#290

Captain Peter Hackett of The Royal Air Force has set a world record for the first flight fuelled with synthetic fuel. The flight lasted 21 minutes on fuel made from captured carbon dioxide from the air combined with hydrogen molecules from water.

Antibiotic Supercharging Antibacterial Gold Particles

#289

Researchers from the Southern University of Science and Technology and Fudan University in China and the University of Leeds in the UK teamed up to demonstrate an improved use of gold nano-particles in the fight against bacteria. The research shows that combined antibacterial methods using gold nano-particles successfully reduced the severity of the bacteria while also increasing the efficacy of antibiotics.

Artificial Synthesis Of Starch From CO2

#283

Scientists in China have developed a method of artificial synthesis of starch from CO2 which is more efficient than natural plant photosynthesis. The hope is to free up 90 percent of cultivated land and freshwater resources by producing starch directly from CO2.

Colours Of The Sky

#283

Did you know that the sky is blue because of Rayleigh scattering? Did you know that the horizon is lighter because of Mie scattering? If not, check out this great article by Daniel Brown about the different colours of the sky.

Glow In The Dark Plants

#282

Scientists at MIT have successfully injected nanoparticles into plants to give them glow in the dark properties, for the second time. The strontium aluminate nanoparticles are coated in silica so as not to damage the plant. Just 10 seconds of exposure to LED or sunlight cause the plants to glow green for up to an hour, at a brightness ten times more than the previous experiment. The plan is to be able to use these glowing plants as passive lighting in outdoor areas, thus reducing the need for street lighting.
