Scientists at the Uni of Southampton have made a major step forward in the development of digital data storage that is capable of surviving for billions of years. Using nanostructured glass, scientists from the University’s Optoelectronics Research Centre (ORC) have developed the recording and retrieval processes of 5D digital data by femtosecond laser writing.

The storage allows unprecedented properties including 360TB/disc data capacity, thermal stability up to 1000C and virtually unlimited lifetime at room temperature (13.8 billion years at 190°C ) opening a new era of eternal data archiving...

Heliafilm – superior low light and high temperature energy harvesting performance.

Note that number, 13.2%. Heliatek, in its research for new organic absorber materials, said it set a new organic photovoltaic (OPV) world record for the direct conversion of sunlight into electricity using OPV multi-junction (using more than one material) cell, thanks to the “excellent low light and high temperature behavior of the organic semiconductor.”

Heliatek said they had a small molecule, vacuum deposition process on a plastic film substrate. The cell is a multi-junction cell combining 3 absorbers. Each of them is dedicated to convert green-, red- or near-infrared light of the wavelength range between 450 and 950 nm into electricity...

Robots at the Fiat Chrysler Automobiles US Warren Stamping Plant are seen in Michigan

Advances in artificial intelligence will soon lead to robots that are capable of nearly everything humans do, threatening tens of millions of jobs in the coming 30 years, experts warned Saturday.

“We are approaching a time when machines will be able to outperform humans at almost any task,” said Moshe Vardi, director of the Institute for Information Technology at Rice University in Texas.

“I believe that society needs to confront this question before it is upon us: If machines are capable of doing almost any work humans can do, what will humans do?” he asked at a panel discussion on artificial intelligence at the annual meeting of the American Association for the Advancement of Science.

Vardi said there w...

An illustration of the ice’s molecular configuration.

Uni of Nebraska-Lincoln-led research team has predicted a new molecular form of the slippery stuff that even Mother Nature has never borne. The proposed ice would be 25% less dense than a record-low form synthesized by a European team in 2014. If synthesized, it would become the 18th known crystalline form of water—and the 1st discovered in the US since before World War II, lowest-density ice to date.

This newest finding represents the latest in a long line of ice-related research from Zeng, who previously discovered a 2D “Nebraska Ice” that contracts rather than expands when frozen under certain conditions.
This new study used a computational algorithm and molecular simulation to determine the ranges of extreme pressure and temperatu...
