Nanoreporters Tell ‘Sour’ Oil from ‘Sweet’

Nanoreporters Tell ‘Sour’ Oil from ‘Sweet’

Scientists at Rice University have created a nanoscale detector that checks for and reports on the presence of hydrogen sulfide in crude oil and natural gas while they’re still in the ground.   The nanoreporter is based on nanometer-sized carbon material developed by a consortium of Rice labs led by chemist James Tour and is [...]

Enhanced Autopilot System to Prevent Accidents

Enhanced Autopilot System to Prevent Accidents

Thirty lines of computer code might have saved Air France flight 447, and 228 passengers and crew aboard, from plunging into the Atlantic Ocean on June 1, 2009, according to new research by Carlos Varela, an associate professor of computer science at Rensselaer Polytechnic Institute. Varela and his research group have developed a computer system [...]

Future Electronics: Super-Efficient Hard Drives

Future Electronics: Super-Efficient Hard Drives

Researchers from ETH Zurich and the Paul Scherrer Institute PSI demonstrate how the magnetic structure can be altered quickly in novel materials. The effect could be used in efficient hard drives of the future.   Data on a hard drive is stored by flipping small magnetic domains. Researchers from the Paul Scherrer Institute PSI and [...]

Electronics Based On a 2-D Electron Gas

Electronics Based On a 2-D Electron Gas

Usually, microelectronic devices are made of silicon or similar semiconductors. Recently, the electronic properties of metal oxides have become quite interesting. These materials are more complex, yet offer a broader range of possibilities to tune their properties. An important breakthrough has now been achieved at the Vienna University of Technology: a two dimensional electron gas [...]

Magnet for Fast and Cheap Data Storage

Magnet for Fast and Cheap Data Storage

Professor Rasing, physicist at Radboud University Nijmegen, came up with a new synthetic material for optical data storage.   Optical data storage does not require expensive magnetic materials as synthetic alternatives work just as well. This is the finding of an international team from York, Berlin and Nijmegen, published Thursday February 27 in Applied Physics [...]

New Record Set for Data-Transfer Speeds

New Record Set for Data-Transfer Speeds

Researchers at IBM have set a new record for data transmission over a multimode optical fiber, a type of cable that is typically used to connect nearby computers within a single building or on a campus. The achievement demonstrated that the standard, existing technology for sending data over short distances should be able to meet [...]

Auto-Fill for Gaps in Computer Programmers’ Code

Auto-Fill for Gaps in Computer Programmers’ Code

Since he was a graduate student, Armando Solar-Lezama, an associate professor in MIT’s Department of Electrical Engineering and Computer Science, has been working on a programming language called Sketch, which allows programmers to simply omit some of the computational details of their code. Sketch then automatically fills in the gaps.   If it’s fleshed out [...]

Early Epidemic Warning: Environment, Health Data

Early Epidemic Warning: Environment, Health Data

The environment has an impact on our health. Preventing epidemics relies on activating the right counter-measures, and scientists are now trying to find out how better use of forecasting can help. The EU’s EO2HEAVEN project developed a risk map for correlating environmental and health data in order to identify where a disease may break out [...]

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 [...]
