Want to have that circuit board as a necklace, bracelet, or ring; well now you can.
The complex little patterns of old circuit boards are highlighted in this lovely handmade collection of jewelry for men and women.

(Phys.org)—By carefully arranging many nanoblocks to form pixels on a metasurface, researchers have demonstrated that they can manipulate incoming visible light in just the right way to create a color “meta-hologram.” The new method of creating holograms has an order of magnitude higher reconstruction efficiency than similar color meta-holograms, and has applications for various types of 3D color holographic displays and achromatic planar lenses.
The researchers, Bo Wang et al., from Peking University and the National Center for Nanoscience and Technology, both in China, have published a paper on the new type of hologram in a recent issue of Nano Letters.
The pixels on the new metasurface consist of three types of silicon nanoblocks whose precise dimensions correspond to the wavelengths of three different colors: red, green, and blue. To enhance the efficiency for the blue light, two identical nanoblocks corresponding to the blue light are arranged in each pixel, along with one nanoblock for red light and one for green light.
Should all new technologies be used?
At the head of all this you will hear about the latest technology from the biotech world, such as CRISPR, that allows scientists to edit the very genome of a plant or animal, but not all technologies that can be used should be used.
While learning to grow massive quantities of organic food in urban landscapes without pesticides is great news, taking away human oversight from farming isn’t necessarily going to make our food better.

AWESOME.
New UCLA research suggests that a gene-based immunotherapy that has shown promising results against cancer could also be used against HIV, the virus that causes AIDS.
In a study to be published in an August issue of the bi-monthly peer-reviewed Journal of Virology, researchers with the UCLA AIDS Institute and Center for AIDS Research found that recently discovered potent antibodies can be used to generate chimeric antigen receptors, or CARs, that can be used to kill cells infected with HIV-1.
CARs are artificially created immune T-cells that have been engineered to produce receptors on their surface that are designed to target and kill specific cells containing viruses or tumor proteins. The use of these chimeric receptors is currently the focus of gene immunotherapy against cancer, but they could also be used to create a strong immune response against HIV, said Dr. Otto Yang, professor of medicine in the division of infectious diseases at the David Geffen School of Medicine at UCLA and the study’s corresponding author.
