You might think it was a simple law of physics that most solids melt as they get hotter, and harden as they get colder. A few materials, however, do just the opposite – they melt as they cool. Researchers at the Massachusetts Institute of Technology (MIT) have recently discovered that by dissolving certain metals into silicon, they can add that silicon compound to the relatively short list of exotic substances that exhibit retrograde melting. Their accomplishment could ultimately result in less expensive solar cells and electronic devices.  Read More

Intel engineer, Dr. Mario Paniccia, holds the thin optical fiber used to carry data from o...

Today’s computer components are connected to each other using copper cables or traces on circuit boards. Due to the signal degradation that comes with using metals such as copper to transmit data, these cables have a limited maximum length. This limits the design of computers, forcing processors, memory and other components to be placed just inches from each other. Intel has announced an important breakthrough that could see light beams replace the use of electrons to carry data in and around computers, enabling data to move over much longer distances and at speeds many times faster than today’s copper technology.  Read More

Greg Dawe demonstrates the HUVR device that lets users see and 'feel' 3D images

It’s not uncommon to see children attempt to reach out and touch objects the first time they don 3D glasses and sit down in front of a 3D TV. Researchers at the University of California, San Diego, have created a new virtual reality device that enables users to do just that. The relatively low-cost device called the Heads-Up Virtual Reality device (HUVR) combines a consumer 3D HDTV panel and a touch-feedback (haptic) device to enable users not only to see a 3D image, but “feel” it too.  Read More

Fujitsu's new resistive multi-touch panel detects finger and stylus input simultaneously

Fujitsu has announced the release of multi-input resistive touch panels with the ability to detect simultaneous inputs. This means that potentially you could have input coming from your finger and from a stylus at the very same time. While multi-touch is nothing new to most readers (especially those with a taste for Apple products), it should be clarified that this functionality is normally associated with capacitive touch screens and not resistive panels like these new ones from Fujitsu.  Read More

An advanced cooling technology being developed for high-power electronics in military and automotive systems is capable of handling roughly 10 times the heat generated by conventional computer chips. The new type of cooling system can be used to prevent overheating of devices called insulated gate bipolar transistors, high-power switching transistors used in hybrid and electric vehicles. The chips are required to drive electric motors, switching large amounts of power from the battery pack to electrical coils needed to accelerate a vehicle from zero to 60 mph in 10 seconds or less.  Read More

Sharp's new BD-HDW700 and BD-HDW70 Blu-ray disc recorders and VR-100BR1 media will be the ...

In April this year, the Blu-ray Disc Association (BDA) announced the final specifications for the new multi-layer recordable Blu-ray Disc format which can more than double the storage capacity of existing 50GB dual layer discs. The new BDXL format supports rewritable discs of up to 100GB and 128GB for write-once recordable discs. Looks like Sharp gets to claim bragging rights as the first company to release both media and hardware that supports the new standard – two new BDXL compatible AQUOS Blu-ray Disc recorders, as well as 100GB write-once BDXL format media to the Japanese market this month.  Read More

Min-Feng Yu, a professor of mechanical science and engineering, has developed a novel appr...

The miniaturization of electronics has seen the wiring of connections between chips and circuit boards become a substantial obstacle. Such connections are traditionally made from pre-fabricated metal wires that connect to a designated bonding pad on a chip. However, many microelectronic devices are much smaller than the required 50-by-50 micron square bonding site, prohibiting integrated functions on a very small scale. Engineers at the University of Illinois have now developed a novel direct-writing method for manufacturing metal interconnects that could enable the further shrinking of integrated circuits and expand microelectronics.  Read More

Accidentally spilling a cup of coffee over a power strip will, at best, probably cause the connected equipment to stop working. On the other hand, such water-related electrical mishaps could lead to serious injury or even be fatal for the user. Wet Circuits has introduced a water resistant power strip that looks to avoid such situations by protecting internal wiring and minimizing the flow of electricity upon contact with water.  Read More

Microsoft InstaLoad lets you insert batteries in any direction

For batteries to work, they need to go in the right way. It's one of those fundamental rules that we all pick up from an early age, but Microsoft has just announced an innovation that turns all that on its head – literally. Known as "InstaLoad" battery installation, the technology allows you to insert a battery without having to worry about positive and negative polarity. That's idiot-proofing of the highest order!  Read More
