Scientists Have Built a Real Star Trek ‘Replicator’ That Builds Objects With Light

Posted by in category: futurism

Year 2019 o.o!


3D printers work by laboriously printing objects layer by layer. For larger objects, that process can take hours or even days.

Edible holograms could decorate or even authenticate food

Year 2021 face_with_colon_three


Remember back in the mid-80s, when mass-produced holograms were such a big deal? Since then, they’ve become common on credit cards, currency and other items. Now, thanks to new research, you can actually eat the things.

First of all, why would anyone want an edible hologram? Well, along with simply being used for decorative purposes, they could conceivably also serve to show that a food item hasn’t been tampered with, or to display its name and/or ingredients in a way that proves it isn’t a counterfeit product.

Using Light to Manipulate Neuron Excitability

Posted by in categories: genetics, neuroscience

Summary: A new optogenetics-based technique allows researchers to control neuron excitability.

Source: MIT

Nearly 20 years ago, scientists developed ways to stimulate or silence neurons by shining light on them. This technique, known as optogenetics, allows researchers to discover the functions of specific neurons and how they communicate with other neurons to form circuits.

Scientists discover ‘single concise’ phenomenon that determines how long you’ll live

Posted by in category: biotech/medical

Research has shown that people with shorter genes age faster, die sooner and are more prone to disease, and this applies to all animals — scientists found that longer and shorter genes linked to longer and shorter lifespans, respectively Scientists have discovered a “single concise” phenomenon that will be able to determine how long you will live, according to new research.

New materials for the computer of the future

Posted by in categories: computing, particle physics

Novel materials could revolutionize computer technology. Research conducted by scientists at the Paul Scherrer Institute PSI using the Swiss Light Source SLS has reached an important milestone along this path.

Microchips are made from silicon and work on the physical principle of a semiconductor. Nothing has changed here since the first transistor was invented in 1947 in the Bell Labs in America. Ever since, researchers have repeatedly foretold the end of the silicon era—but have always been wrong.

Silicon technology is very much alive, and continues to develop at a rapid pace. The IT giant IBM has just announced the first microprocessor whose transistor structures only measure two nanometers, equivalent to 20 adjacent atoms. So what’s next? Even tinier structures? Presumably so—for this decade, at least.
