Laser Pulse Turns Glass Into a Metal

Laser Pulse Turns Glass Into a Metal

For tiny fractions of a second, quartz glass can take on metallic properties, when it is illuminated be a laser pulse. This has been shown by calculations at the Vienna University of Technology. The effect could be used to build logical switches which are much faster than today’s microelectronics. Quartz glass does not conduct electric [...]

Can Our Computers Get Smaller, More Powerful?

Can Our Computers Get Smaller, More Powerful?

From their origins in the 1940s as sequestered, room-sized machines designed for military and scientific use, computers have made a rapid march into the mainstream, radically transforming industry, commerce, entertainment and governance while shrinking to become ubiquitous handheld portals to the world.   This progress has been driven by the industry’s ability to continually innovate [...]

Sensors That Improve Rail Transport Safety

Sensors That Improve Rail Transport Safety

A new kind of human-machine communication is to make it possible to detect damage to rail vehicles before it’s too late and service trains only when they need it — all thanks to a cloud-supported, wireless network of sensors.   A train running on damaged wheels could easily be heading for serious trouble. This is [...]

World’s First Global Jellyfish Database

World’s First Global Jellyfish Database

An international study, led by the University of Southampton, has led to the creation of the world’s first global database of jellyfish records to map jellyfish populations in the oceans.   The debate regarding future trends, and subsequent ecological, biogeochemical and societal impacts, of jellyfish and jellyfish blooms in a changing ocean is hampered by [...]

Logical Circuits Built Using Living Slime Molds

Logical Circuits Built Using Living Slime Molds

A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors.   Andrew Adamatzky (University of the [...]

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 [...]
