World's first white laser demonstrated

By - August 4, 2015 3 Pictures

Incandescent bulbs, LEDs, and CFLs may soon have to budge up because a new lighting technology is in town – white lasers. Using nanotechnology to create a bespoke semiconducting material, a team of scientists at Arizona State University has developed a laser that can produce white light that is brighter and more efficient than LEDs.

Modified Salmonella eats away at cancer, without a side order of food poisoning

By - April 15, 2015 1 Picture
Though generally a bacteria we'd associate with a severe bout of food poisoning, previous research has suggested that Salmonella needn't always bring bad news and stomach cramps. Certain strains have been shown to kill off cancer cells, but to use them as a form of treatment for humans without inducing any nasty side effects has so far proven difficult. But now, researchers have developed genetically modified salmonella that turns toxic only after it enters a tumor. Read More

New understanding of lizard tails could allow humans to regrow body parts

By - August 21, 2014 1 Picture
If you ever had a pet lizard as a child, it was quite likely a green anole. As is the case with other lizards, they have the ability to break off their own tail when attacked by a predator, and then regrow it. Scientists from Arizona State University recently announced that they have cracked the code regarding that tail regrowth process, and are now hoping that it could be applied to the field of regenerative medicine.

Shelter on the Moon could be the pits

By - July 21, 2014 3 Pictures
Moving into a new neighborhood means finding a place to live, and 45 years after Neil Armstrong set foot on the Moon, our largest satellite is still notoriously short on housing. However, that may be changing as NASA announces that its Lunar Reconnaissance Orbiter (LRO) has discovered over 200 deep pits on the Moon that could not only provide scientists with deeper insights into the geology of the Moon, but could also be used as sites for future Lunar outposts.

Breezing device tracks your metabolism and acts as a fitness coach

By - February 4, 2013 5 Pictures
There are already plenty of devices that allow people to measure factors such as their caloric intake and physical activity levels. While such data can be a vital part of achieving your fitness goals, its usefulness is limited without an understanding of your specific metabolism – if you don’t know how fast you burn calories, for instance, then you won’t know how many you should be consuming and/or burning. That’s why researchers at Arizona State University developed the Breezing portable metabolism tracker. Read More

New software improves measurement of greenhouse gas emissions

By - October 22, 2012 1 Picture
As the old adage goes, knowledge is power. Following this principle, Arizona State University researchers have developed a computer program called Hestia, that is capable of estimating the greenhouse gas emissions of specific roads and even buildings. With its high level level of detail and accuracy, the software can help cities make more precise calculations about their GHG footprint as well as more informed decisions related to carbon mitigation efforts.

Thin-film flexible 'Paperphone' created

By - May 5, 2011 3 Pictures
Researchers from the Human Media Lab at Canada's Queen's University have created a fully-functioning floppy E-Ink smartphone, which they also refer to as a paper computer. Like its thicker, rigid-bodied counterparts, the Paperphone can do things like making and receiving calls, storing e-books, and playing music. Unlike them, however, it conforms to the shape of its user's pocket or purse, and can even be operated through bending actions. Read More

World's first hard X-ray free-electron laser images intact viruses

By - February 7, 2011 4 Pictures
An international team of scientists has obtained the world’s first single-shot images of intact viruses – a technology that could ultimately lead to moving video of molecules, viruses and live microbes. The team was also able to successfully utilize a new shortcut for determining the 3D structures of proteins. Both advances were achieved using the world’s first hard X-ray free-electron laser – the Linac Coherent Light Source (LCLS) – which scientists hope could revolutionize the study of life. Read More

New device developed to make health diagnosis cheaper and quicker

By - August 24, 2010 1 Picture
When bodily fluids such as blood are tested for infectious diseases and unhealthy protein levels, they’re typically mixed with antibodies or other biological reactants to produce a positive or negative reaction. Researchers from Arizona State University (ASU) have now come up with an alternative testing system that they claim is just as accurate, but much simpler, quicker and cheaper. It utilizes LED lights and simple microelectronic amplifiers, and actually uses the sample itself as a diagnostic tool. Because it integrates the sample into the process, inventors Antonia Garcia and John Schneider call their device the Integrascope. Read More
