Can you eat cells? Computer model predicts which organisms are capable of phagocytosis

Tue, 02/20/2018 - 11:34am
Researchers have created a computational model capable of predicting whether or not organisms have the ability to 'eat' other cells through a process known as phagocytosis. The model may be a useful tool for large-scale microbe surveys and provides valuable insight into the evolution of complex life on Earth, challenging ideas put forward in recent studies.

How health authorities fight the spread of infectious diseases

Tue, 02/20/2018 - 11:34am
Public outreach campaigns can prevent the spread of devastating yet treatable diseases such as tuberculosis, malaria and gonorrhea. But ensuring these campaigns effectively reach undiagnosed patients, who may unknowingly spread the disease to others, is a major challenge for cash-strapped public health agencies. Now, a team of researchers has created an algorithm that can help policymakers reduce the overall spread of disease.

Alexa, how do word senses evolve?

Tue, 02/20/2018 - 7:41am
A new paper is the first to look at 1,000 years of English development and detect the kinds of algorithms that human minds have used to extend existing words to new senses of meaning. This kind of 'reverse engineering' of how human language has developed could have implications for natural language processing by machines.

Fake news ‘vaccine’: online game may ‘inoculate’ by simulating propaganda tactics

Tue, 02/20/2018 - 6:35am
A new online game puts players in the shoes of an aspiring propagandist to give the public a taste of the techniques and motivations behind the spread of disinformation -- potentially 'inoculating' them against the influence of so-called fake news in the process.

Real-time Captcha technique improves biometric authentication

Mon, 02/19/2018 - 11:12am
A new login authentication approach could improve the security of current biometric techniques that rely on video or images of users' faces. Known as Real-Time Captcha, the technique uses a unique 'challenge' that's easy for humans -- but difficult for attackers who may be using machine learning and image generation software to spoof legitimate users.

Computers aid discovery of new, inexpensive material to make LEDs with high color quality

Mon, 02/19/2018 - 9:48am
Computers have helped researchers develop a new phosphor that can make LEDs cheaper and render colors more accurately. Researchers predicted the new phosphor using supercomputers and data mining algorithms, then developed a simple recipe to make it in the lab. Unlike many phosphors, this one is made of inexpensive, earth-abundant elements and can easily be made using industrial methods. As computers predicted, the new phosphor performed well in tests and in LED prototypes.

Unconventional superconductor may be used to create quantum computers of the future

Mon, 02/19/2018 - 4:17am
With their insensitivity to decoherence what are known as Majorana particles could become stable building blocks of a quantum computer. The problem is that they only occur under very special circumstances. Now researchers have succeeded in manufacturing a component that is able to host the sought-after particles.
