Automated organization, multi-RAT and multi-layer heterogeneous networks are being listed in mobile of 2020, at least by the kinds of committees that brought us bluetooth 7 years late. It's the 5G era, what vendors say will be the first meaningful unified wideband mobile communication system. 

A new paper suggests a need for a fundamental rethink of the evolutionary path of enzymes, the proteins vital to all life on Earth.

Enzymes catalyze a vast array of biologically relevant chemical reactions even in the simplest living cells but biochemist Dr. Wayne Patrick of University of Otago and colleagues assert that while people tend to imagine evolution as a slow and steady march, from barely functional life forms in the primordial soup towards a modern-day pinnacle of near perfection, that may not be true. 

There is not the slightest doubt that the the universe is real. It is three-dimensional.

But one popular alternative notion has been the "holographic principle", which asserts that a mathematical description of the universe only requires two dimensions. What we perceive as three dimensional may just be the image of two dimensional processes on a huge cosmic horizon. 

Up until now, this speculation has only been mathematically analyzed in exotic spaces with negative curvature. Math, like any language, can talk about lots of things that are not possible and such spaces are quite different from the space in our own universe.

A new paper suggests that the holographic principle even holds in a flat spacetime.

Scientists have developed the first liquid nanoscale laser and it's tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser technology could lead to practical applications, such as a new form of a "lab on a chip" for medical diagnostics.The laser's color can be changed in real time when the liquid dye in the microfluidic channel above the laser's cavity is changed.

The brain function of people addicted to cocaine is different from that of people who are not addicted, and often linked to highly impulsive behavior. The variation in the way that different regions of the brain connect, communicate and function in people addicted to cocaine is an observation published in NeuroImage: Clinical. 

Cocaine addiction exists among an estimated 800,000 people in the U.S. alone, but despite decades of attempts, FDA-approved medications for cocaine use disorder remain to be discovered. 

There is bad news for those planning to go to Mars in the near future: a study in mice has suggested that radiation in space could cause cognitive decline in astronauts. However, we know from past research that mental, social and physical exercise can boost cognitive functions. With planned Mars missions moving ever closer, it might be be worth exploring activity as a way to counter radiation damage.

Researchers have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation.

In a paper published this week in Optica, Fabrizio Buccheri and Xi-Cheng Zhang demonstrate that an approach for generating terahertz waves using intense laser pulses in air - first pioneered in 1993 - can be done with much lower power lasers, a major challenge until now. Ph.D. student and lead author Buccheri explains that they exploited the underlying physics to reduce the necessary laser power for plasma generation. He adds that it could potentially be improved for applications in the monitoring of explosives or drugs.

Mammals, birds, reptiles, amphibians, fish, even you are a vertebrate. And now for the first time, scientists from around the world are coming together to study them on a molecular level.

"The Genome 10k Project is our first look at vertebrate animal life," said David Haussler, a biomolecular engineer at the University of California, Santa Cruz. "We're trying to get at least 10,000 species represented in our genome collection," he said.

The first large international study to investigate the late side-effects of a combination of two forms of brachytherapy to treat cervical cancer has shown that the technique successfully delivers higher radiation doses to the tumour without an increase in treatment-related problems afterwards.

It's not a surprise that in a modern materialistic society, the desire to buy the latest iGimmick will lead to sadness if the money to do so is not available but we fortunately have the statistics to back that up. The recent Great Recession was accompanied by a significant and sustained  major depression claims by U.S. adults, according to a study published in the Journal of Clinical Psychiatry.
