A long line of research links poverty and depression. Now, a study by Duke University scientists shows how biology might underlie the depression experienced by high-risk adolescents whose families are socio-economically disadvantaged.
The study, published May 24, 2016 in the journal Molecular Psychiatry, combined genetics, brain imaging and behavioral data gathered as adolescents were followed for more than three years as part of a larger study.

Using the power of nano to solar power our homes at night.
MIT researchers have built a new experimental solar cell which could greatly enhance power efficiency. The “Shockley-Queisser’ limit is the estimated maximum efficiency of a solar cell, which is commonly about 32%; that means almost 70% of energy is wasted in the form of heat.
One way to reduce energy loss is by stacking cells. However if sunlight could be turned into heat and then be re-emitted as light, the solar cells could utilize more energy. Solar cells work best with visible light which occurs midway of the radiation spectrum. As a result the radiations with shorter and greater wavelengths usually go to waste.

Non-diffracting Bessel vortex beams exhibit diverse propagation regimes in glass that can be observed with a novel imaging strategy.
High-power femtosecond pulses have become a key tool in processing of transparent materials (e.g., glass and sapphire) for the present and the next generation of consumer electronics.1 Associated major industrial challenges include high-quality and high-speed cutting of screen glass for smartphones, camera windows, or drilling of through-vias (vertical interconnect access) in interposers for the circuitry of 3D electronic chips. Ultrafast laser pulses (on picosecond or femtosecond timescales) allow for structuring transparent materials with high levels of accuracy. When the laser pulses propagate into the transparent dielectrics, they usually undergo high distortions.2 These distortions arise because of the nonlinear Kerr self-focusing effect and because of the interaction of the pulse with the plasma, which the pulses generate in the material. The propagation is therefore highly nonlinear and prevents uniform energy deposition along the beam propagation.

3D Stem Cells — definitely makes sense given the organ, skin graffe, etc. produce on 3D printers in today’s labs.
JERUSALEM – Israeli 3D printer firm Nano Dimension has successfully lab-tested a 3D bioprinter for stem cells, paving the way for the potential printing of large tissues and organs, the company said on Wednesday.
While 3D printers are used already to create stem cells for research, Nano Dimension said the trial, conducted with Israeli biotech firm Accellta Ltd, showed its adapted printer could make large volumes of high resolution cells quickly.
