A New Laser for a Faster Internet

A New Laser for a Faster Internet

A new laser developed by a research group at Caltech holds the potential to increase by orders of magnitude the rate of data transmission in the optical-fiber network — the backbone of the Internet.   The study was published the week of February 10-14 in the online edition of the Proceedings of the National Academy [...]

Smarter Caching, Better Chip Performance

Smarter Caching, Better Chip Performance

Cleverer management of the local memory banks known as ‘caches’ could improve computer chips’ performance while reducing their energy consumption.   Computer chips keep getting faster because transistors keep getting smaller. But the chips themselves are as big as ever, so data moving around the chip, and between chips and main memory, has to travel [...]

Early Warning: Internet Surveillance Predicts Disease Outbreak

The habit of Googling for an online diagnosis before visiting a GP can provide early warning of an infectious disease epidemic. In a new study published in Lancet Infectious Diseases, internet-based surveillance has been found to detect infectious diseases such Dengue Fever and Influenza up to two weeks earlier than traditional surveillance methods. Senior author [...]

In Search of . . . Time Travelers

In Search of . . . Time Travelers

It started over a poker game. Astrophysicist Robert Nemiroff and his students were playing cards (for chips) last summer, chatting about Facebook. They wondered: If there were time travelers among us, would they be on social media? How would you find them? Could you Google them?   “We had a whimsical little discussion about this,” [...]

Growing Giants: Huge Grains of Copper Promote Better Graphene Growth

Growing Giants: Huge Grains of Copper Promote Better Graphene Growth

To technology insiders, graphene is a certified big deal. The one-atom thick carbon-based material elicits rhapsodic descriptions as the strongest, thinnest material known. It also is light, flexible, and able to conduct electricity as well as copper. Graphene-based electronics promise advances such as faster internet speeds, cheaper solar cells, novel sensors, space suits spun from [...]

Laser Light at Useful Wavelengths from Semiconductor Nanowires

Laser Light at Useful Wavelengths from Semiconductor Nanowires

Thread-like semiconductor structures called nanowires, so thin that they are effectively one-dimensional, show potential as lasers for applications in computing, communications, and sensing. Scientists at the Technische Universität München (TUM) have demonstrated laser action in semiconductor nanowires that emit light at technologically useful wavelengths and operate at room temperature.   They now have documented this [...]

The Secret Beauty of the World Wide Web

The Secret Beauty of the World Wide Web

From a distance, these newly created visualizations look likes stars exploding, fireworks or simply striking patterns — but what you’re actually looking at are the hidden dimensions of the World Wide Web.   Dr Martyn Dade Robertson from Newcastle University creates the stunning artworks, known as Data Portraits. He has developed a way of mapping [...]

Topological Insulators: Breaking Symmetry for Faster Computers

Topological Insulators: Breaking Symmetry for Faster Computers

Ordinary insulating solids, such as diamond, have energy bands that are fully occupied by electrons. The conducting band is so far away from the valence band in diamond that electrons do not have sufficient energy to move — the ‘band gap’ is large — therefore no electric current can be carried.   In recent years, [...]

Will 2-D Tin Be the Next Super Material?

Will 2-D Tin Be the Next Super Material?

A single layer of tin atoms could be the world’s first material to conduct electricity with 100 percent efficiency at the temperatures that computer chips operate, according to a team of theoretical physicists led by researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University.   Researchers call the new [...]
