Cybersecurity Experts Discover Lapses in Heartbleed Bug Fix

A detailed analysis by cybersecurity experts from the University of Maryland found that website administrators nationwide tasked with patching security holes exploited by the Heartbleed bug may not have done enough. First disclosed in April 2014, Heartbleed presents a serious vulnerability to the popular OpenSSL (Secure Sockets Layer) software, allowing anyone on the Internet to [...]

Understanding Nature Without Supercomputers

Understanding Nature Without Supercomputers

In an article published in Frontiers in Computational Neuroscience by Okinawa Institute of Science and Technology Graduate University’s Professor Robert Sinclair, he suggests that there still is a place in science in modern times for the interpretation of results using rational numbers or simple ratios. In a time where supercomputers dominate scientific analysis, Prof. Sinclair [...]

Harnessing Error-Prone Chips

Harnessing Error-Prone Chips

As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption.   With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation. [...]

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 [...]
