Finding Software Errors Via Genetic Algorithms

Finding Software Errors Via Genetic Algorithms

According to a current study from the University of Cambridge, software developers are spending about the half of their time on detecting errors and resolving them. Projected onto the global software industry, according to the study, this would amount to a bill of about 312 billion US dollars every year. “Of course, automated testing is […]

40 Percent of Parents Learn How to Use Technology from Their Children

40 Percent of Parents Learn How to Use Technology from Their Children

Just how are adults learning to use technology? Chances are if you are a parent, your child is teaching you. A recent paper published in the Journal of Communication found that between 30%-40% of parents were taught how to use the computer and Internet from their children.   Teresa Correa, University Diego Portales (in Santiago, […]

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 […]

CT and 3-D Printers Used to Recreate Dinosaur Fossils

CT and 3-D Printers Used to Recreate Dinosaur Fossils

Data from computed tomography (CT) scans can be used with three-dimensional (3-D) printers to make accurate copies of fossilized bones, according to new research published online in the journal Radiology.   Fossils are often stored in plaster casts, or jackets, to protect them from damage. Getting information about a fossil typically requires the removal of […]

Spinning Atoms in Light Crystals

Spinning Atoms in Light Crystals

After more than 40 years of intense research, experimental physicists still seek to explore the rich behaviour of electrons confined to a two-dimensional crystalline structure exposed to large magnetic fields. Now a team of scientists working with Prof. Immanuel Bloch (Chair for Experimental Physics at the Ludwig-Maximilians-Universität Munich and Director at MPQ) in collaboration with […]

Topological Light: Living On the Edge

Topological Light: Living On the Edge

Topology — the understanding of how things are connected — remains abstract, even with the popular example of doughnuts and coffee cups. This concept, esoteric as it appears, is also neat because it is the basis for creating ultrastable quantum “playgrounds.” In topological systems, certain quantum behaviors can be carefully probed and even harnessed for […]

World Record: Wireless Data Transmission at 100 Gbit/S

World Record: Wireless Data Transmission at 100 Gbit/S

Extension of cable-based telecommunication networks requires high investments in both conurbations and rural areas. Broadband data transmission via radio relay links might help to cross rivers, motorways or nature protection areas at strategic node points, and to make network extension economically feasible. In the current issue of the nature photonics magazine, researchers present a method […]

Innovation in Renewable-Energy Technologies Is Booming

Innovation in Renewable-Energy Technologies Is Booming

The number of patents issued for renewable-energy technologies has risen sharply over the last decade, according to new research from MIT and the Santa Fe Institute (SFI). The study shows that investments in research and development, as well as in the growth of markets for these products, have helped to spur this dramatic growth in […]

Flawed Diamonds: Gems for New Technology

Flawed Diamonds: Gems for New Technology

A team of researchers led by University of Arizona assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers — defects in which two adjacent carbon atoms in the diamond’s crystal structure are replaced by a single nitrogen atom and an empty gap.   These […]

Neglected Statistical Tool Could Help Robots Better Understand the Objects in the World Around Them

Neglected Statistical Tool Could Help Robots Better Understand the Objects in the World Around Them

Object recognition is one of the most widely studied problems in computer vision. But a robot that manipulates objects in the world needs to do more than just recognize them; it also needs to understand their orientation. Is that mug right-side up or upside-down? And which direction is its handle facing?   To improve robots’ […]
