Researchers have created silicon wire four atoms wide and one atom tall capable of carryin...

The world's narrowest silicon wires with a cross section of a mere four atoms by one atom have been created by a team of developers from the University of New South Wales, the University of Melbourne and Purdue University. The wires are fully functioning, with current-carrying capacity equivalent to that of a microprocessor's copper cable, despite being 20 times thinner - and 10,000 times narrower than a human hair.  Read More

Researchers have developed a biofuel cell to enable the development of 'insect cyborgs' (I...

Research into developing insect cyborgs for use as first responders or super stealthy spies has been going on for a while now. Most research has focused on using batteries, tiny solar cells or piezoelectric generators to harvest kinetic energy from the movement of an insect’s wings to power the electronics attached to the insects. Now a group of researchers at Case Western Reserve University have created a power supply that relies just on the insect’s normal feeding.  Read More

Salmon ... they’re good to eat, provide a livelihood for fishermen, are an important part of their ecosystem, and now it seems that they can store data. More specifically, their DNA can. Scientists from National Tsing Hua University in Taiwan and the Karlsruhe Institute of Technology in Germany have created a “write-once-read-many-times” (WORM) memory device, that combines electrodes, silver nanoparticles, and salmon DNA. While the current device is simply a proof-of-concept model, the researchers have stated that DNA could turn out to be a less expensive alternative to traditional inorganic materials such as silicon.  Read More

Scientists have reached a major milestone in the field of stem cell research. A team at the Oregon National Primate Research Center (ONPRC) say their work has led to the first successful birth of three chimeric monkeys - monkeys developed from stem cells taken from two separate embryos.  Read More

A prototype system has been created for cleaning and heating the air in chicken and swine ...

If you’ve ever so much as stepped into a chicken or swine barn, you’ll know that they can be very, very smelly places. When vented outdoors, the air from these buildings does more than just make the area stink – it can actually be a major source of air pollution and greenhouse gases. Fortunately, however, researchers from North Carolina State University and West Virginia University have created a system that not only helps clean the air going out of the barns, but it heats up the air coming in from outside.  Read More

What does it really feel like to be 75 years old? A group of researchers in MIT's Agelab have created a suit to help people understand what it might be like to navigate the world as a senior citizen. Called AGNES (Age Gain Now Empathy System), the suit replicates what it might be like to be in a 75-year-old body, replicating dexterity, flexibility, motor, and visual elements into a suit that can be worn by people of all ages.  Read More

Is this cyclone a tremor trigger? (Photo: Shutterstock)

Hurricanes and typhoons could contribute to other natural disasters that occur long after the rain and winds subside. A new study led by University of Miami (UM) scientist Shimon Wdowinski finds a link between earthquakes and tropical storms, and shows that they may have actually initiated some major temblors, including the recent 2010 quakes in Haiti and Taiwan.  Read More

British researchers say they've seen a new particle using data from the ATLAS experiment at the Large Hadron Collider. The chi b(3P) is the first new particle that has been clearly observed using the LHC, the world's largest particle accelerator, which is housed in a 17-mile (27-km) long tunnel near the border of Switzerland and France.  Read More

Hematite nanoparticle film (red) with functional phycocyanin network (green) attached

Recently, scientists from the Swiss research institute EMPA, along with colleagues from the University of Basel and the Argonne National Laboratory in Illinois took a cue from photosynthesis and discovered that by coupling a light-harvesting plant protein with their specially designed electrode, they could substantially boost the efficiency of photo-electrochemical cells used to split water and produce hydrogen - a huge step forward in the search for clean, truly green power.  Read More

The new diode is made from two silicon rings that measure just 10 microns in diameter and ...

When it comes to speed, photons leave electrons for dead and have a higher bandwidth, which means optical computers will be much faster than their current electron-based cousins. While optical diodes for use in optical information processing systems already exist, these require external assistance to transmit signals so cannot be readily integrated into computer chips. Now researchers at Purdue University have developed a “passive optical diode” that not only doesn’t require any outside help to transmit signals, but is also so small that millions would fit on a computer chip, potentially leading to faster, more powerful information processing and supercomputers.  Read More
