A full-duplex transceiver on an integrated circuit could realize vastly increased data exc...

Full-duplex radio communication usually involves transmitters and receivers operating at different frequencies. Simultaneous transmission and reception on the same frequency is the Holy Grail for researchers, but has proved difficult to achieve. Those that have been built have proven complex and bulky, but to be commercially useful in the ever-shrinking world of communications technology, miniaturization is key. To this end, engineers at Columbia University (CU) claim to have created a world-first, full-duplex radio transceiver, all on one miniature integrated circuit.  Read More

For a long time, scientists have been searching for an answer as to how galaxy clusters regulate the number of stars they create. Given that the amount of interstellar gas used to create the stellar giants exists in such abundance, this theoretically allows for the creation of many times the current number of stars. A team of researchers from MIT, Columbia University and Michigan State University believe they have found the answer.  Read More

Nanometer-sized “drones” that deliver drugs to heal and stabilize fat deposits in arteries...

Scientists have developed targeted, biodegradable nano "drones" to deliver anti-inflammatory drugs that heal and stabilize arterial plaque in mice. Their work could pave the way for more effective prevention of heart attack and stroke in humans caused by atherosclerosis, in which artery walls thicken and suffer reduced plasticity due to an accumulation of white blood cells.  Read More

Scientists have developed a smartphone accessory capable of detecting multiple disease mar...

That smartphones have evolved to be capable of much more than making and receiving calls won't be news to many, but work being done to refashion them as medical diagnostics tools is proving to be a very promising area of mobile innovation. The latest big-picture idea to emerge in this area is a smartphone dongle capable of detecting three infectious disease markers within 15 minutes, requiring only a finger prick of blood.  Read More

Elizabeth Hillman, associate professor of biomedical engineering at Columbia University Medical Center (CUMC), has developed a new 3D microscope prototype dubbed "SCAPE" (Swept Confocally Aligned Planar Excitation Microscopy), which requires no mounting of samples or other special preparation, and is capable of imaging freely moving living samples at speeds 10 to 100 times faster than current laser-scanning microscopes.  Read More

Cocoa flavanols, naturally occurring compounds in cocoa, can reverse age-related memory de...

Do you forget where you left your keys or parked the car, or have difficulty remembering the names of people you’ve just met? The good news is that chocolate – or more specifically, naturally occurring compounds in cocoa called flavanols – can reverse age-related memory decline in healthy older adults, according to a Columbia University Medical Center (CUMC) study.  Read More

A sample of the MoS2 material that could be the basis for piezoelectric devices that are o...

Researchers from Columbia University and the Georgia Institute of Technology are laying claim to having observed piezoelectricity in an atomically thin material for the first time. The effect was demonstrated in the world's thinnest electric generator made from a two-dimensional molybdenum disulfide (MoS2) material, which had previously been predicted to exhibit such properties.  Read More

The direction of magnetic north suddenly reversed about 786,000 years ago, with new resear...

A new study by a team of scientists from Italy, France, Columbia University and the University of California, Berkeley, demonstrates that the Earth's magnetic field could change polarity in less than 100 years. The last magnetic reversal occurred some 786,000 years ago and was previously thought to have taken several thousand years but, if the researchers are right, the real time it may take for the flip to occur could actually be closer to the span of a human life.  Read More

 XRay helps users see how popular online services track their personal information  (Image...

A new software tool developed at Columbia University is providing valuable insights into how some very popular websites make use of the sensitive data they collect from their users. The software could help sniff out potential abuses from advertisers and contribute in making the usage of sensitive data a lot more transparent to the end user.  Read More

Researchers at Columbia University School of Engineering performing a large-scale measurement study on the Google Play marketplace have revealed crucial security problems, including secret key data stored by developers in their apps that, if stolen, could be exploited to steal user data from the likes of Amazon and Facebook.  Read More
