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

The humidity-driven flexing of a spore-covered piece of latex rubber (right) drives the mo...

Ozgur Sahin believes that water evaporation is the largest power source in nature. In an effort to demonstrate the potential of this untapped resource, Sahin and his fellow researchers have created prototype electrical generators with rubber sheets that move in response to changes in humidity thanks to a coating of bacterial spores.  Read More

Scientists convert human embryonic stem cells into functional lung epithelial cells (green...

Researchers at Columbia University Medical Center (CUMC) have transformed human stem cells into functional lung cells, paving the way for ultimately creating bioengineered lungs using the patient's own cells. Besides being able to generate lung tissue for transplants, these cells could also be used to study lung development and potentially find more advanced treatments for lung diseases.  Read More

The development of graphene based nanoelectromechanical systems could lead to even slimmer...

A team of engineers from Columbia University has created a nano-mechanical system with the ability to create FM radio signals. In other words, they've built what is effectively the world’s smallest FM radio transmitter.  Read More

Researchers have created new human hairs using dermal papilla cells found inside the base ...

Current hair transplantation techniques essentially rob Peter to pay Paul, redistributing hair, usually from the back of the head, to the balding area. However, according to Angela M. Christiano from Columbia University Medical Center, about 90 percent of women with hair loss are not strong candidates for hair transplantation surgery because of insufficient donor hair. A new technique developed by Dr Christiano and colleagues that generates new human hair growth from a patient's own cells could make transplantation feasible for such women, as well as men in the early stages of baldness.  Read More

Columbia University researchers have come up with a way to produce large joined sheets of ...

A study conducted at Columbia University has revealed that even when stitched together from much smaller fragments, large sheets of graphene still retain much of their mechanical properties. The discovery may be a crucial step forward in the mass-production of carbon nanotubes that could be used to manufacture flexible electronics, ultra-light and strong materials, and perhaps even the first space elevator.  Read More

The MESSENGER spacecraft has made a compelling case for the presence of water in the form of ice on the surface of the Solar System's smallest and innermost planet, Mercury. The case is supported by three independent groups of evidence from different sensors aboard the Mercury orbiter.  Read More

The identification of the mechanism that causes white fat cells to become brown fat cells ...

Earlier this year, a team from UC San Francisco reported on the discovery that a class of commonly prescribed type-2 diabetes drugs, called TZDs (thiazolidinediones, such as Actos and Avandia), promoted the conversion of energy-storing white fat cells into energy-burning brown fat cells. Now researchers at Columbia University Medical Center (CUMC) have identified the mechanism that causes this change to take place, potentially leading to new techniques to treat obesity and type-2 diabetes.  Read More

Research has shown the popular music has become louder and more homogeneous over time (Pho...

If you suspect that songs today tend to sound the same, it turns out you're right. A group of Spanish scientists looked at a huge database of songs and analyzed their trends, publishing their results in the scientific journal Nature. What they found was proof positive that, over the last few decades, songs have progressively gotten louder, decreased their pitch transitions, and generally become more homogeneous.  Read More

Its idea may be simple, but that did not stop Radiator Labs winning the MIT Clean Energy Prize with its controllable box that can be retrofitted to radiators to boost the efficiency of hot water and steam heating systems. The heavily insulated housings physically cover the radiator, trapping heat in the system, and strictly controlling the amount that is let into the room. This prevents homes becoming over-heated, and wasteful heat loss as people open windows to compensate.  Read More
