Period tracking apps failing users in basic ways, study finds
A new study finds that smartphone apps to track menstrual cycles often disappoint users with a lack of accuracy, assumptions about sexual identity or partners, and an emphasis on pink and flowery form over function and customization. The University of Washington research team collected data from 2,000 reviews of popular period tracking apps, surveyed 687 people and conducted in-depth interviews with a dozen respondents to understand how and why they tracked their menstrual cycles.

Smartphone security hole: ’Open port’ backdoors are widespread
ANN ARBOR'A sweeping study of an internet communication mechanism common in mobile devices has revealed that so-called 'open ports' are much more vulnerable to security breaches than previously thought. The vulnerability the University of Michigan researchers highlighted is most pronounced in Android apps that let users share data across devices and connect to their phones from their computers.

Artificial intelligence can accurately predict future heart disease and strokes, study finds
Computers that can teach themselves from routine clinical data are potentially better at predicting cardiovascular risk than current standard medical risk models, according to new research at the University of Nottingham. The team of primary care researchers and computer scientists compared a set of standard guidelines from the American College of Cardiology (ACC) with four 'machine-learning' algorithms - these analyse large amounts of data and self-learn patterns within the data to make predictions on future events - in this case, a patient's future risk having of heart disease or a stroke.

Rare Supernova Discovery Ushers in New Era for Cosmology
With the help of an automated supernova-hunting pipeline and a galaxy sitting 2 billion light years away from Earth that's acting as a 'magnifying glass,'' astronomers have captured multiple images of a Type Ia supernova'the brilliant explosion of a star'appearing in four different locations on the sky.

Biased bots: Human prejudices sneak into AI systems
Many experts think of artificial intelligence systems as coldly logical and objectively rational. But in a new study researchers have demonstrated how machines can be reflections of us and acquire human-like biases. Common machine learning programs, when trained with ordinary human language available online, can acquire cultural biases embedded in the patterns of wording, the researchers found.

Unraveling the mystery of snowflakes, from the Alps to Antarctica
Using a special multi-angle camera, EPFL researchers have gained important insights into the structure of snowflakes. Their aim is to improve the accuracy of snowfall measurements and winter weather forecasts. Imagine taking pictures of thousands of snowflakes from three different angles with a specialized instrument installed at an altitude of 2,500 meters.

Neuroscientists Lay Groundwork for Identifying Algorithm Behind Information Processing in the Neocortex
Neuroscientists Lay Groundwork for Identifying Algorithm Behind Information Processing in the Neocortex-CMU News - Carnegie Mellon University Alison Barth says knowing that algorithm is critical to understanding the role the neocortex plays in many vital functions. Neuroscientists at Carnegie Mellon University have identified principles for information processing in the neocortex, an evolutionarily expanded area of the brain critical for cognition.

Google’s AI tool for video searching can be easily deceived
University of Washington researchers have shown that Google's new tool that uses machine learning to automatically analyze and label video content can be deceived by inserting a photograph periodically and at a very low rate into videos. After they inserted an image of a car into a video about animals, for instance, the system returned results suggesting the video was about an Audi.

Machine translation: going beyond sentence by sentence
In working sentence by sentence, translation algorithms omit much of the context and make mistakes. A project supported by the SNSF has developed new algorithmic techniques designed to do a better job of taking the entire text into account. Researchers supported by the Swiss National Science Foundation (SNSF) have come up with a new approach to improving machine translation tools such as the famous Google Translate, which processes hundreds of billions of words daily.

Deep learning algorithm could aid drug development
Combining computer science and chemistry, researchers show how an advanced form of machine learning that works off small amounts of data can be used to solve problems in drug discovery. Artificially intelligent algorithms can learn to identify amazingly subtle information, enabling them to distinguish between people in photos or to screen medical images as well as a doctor.

New study to investigate links between cybercrime and autistic traits
A new project between the University's Centre for Applied Autism Research , the charity Research Autism and the cybercrime unit of the National Crime Agency (NCA) - launched today (Monday 3 April) - will examine the links between cybercrime and autistic-like personality traits . While autism and higher autistic-like traits appear to be more prevalent among cyber criminals than for other types of crime, this link remains unproven.

Finding Faces in a Crowd
An automated face detection method developed at Carnegie Mellon University enables computers to recognize faces in images at a variety of scales, including tiny faces composed of just a handful of pixels. Spotting a face in a crowd, or recognizing any small or distant object within a large image, is a major challenge for computer vision systems.

When deep learning mistakes a coffee-maker for a cobra
'Is this your sister'' That's the kind of question asked by image-recognition systems, which are becoming increasingly prevalent in our everyday devices. They may soon be used for tumor detection and genomics, too. These systems rely on what is known as 'deep-learning' architectures - an exciting new development in artificial learning.

Making better decisions when outcomes are uncertain
Markov decision processes are mathematical models used to determine the best courses of action when both current circumstances and future consequences are uncertain. They've had a huge range of applications - in natural-resource management, manufacturing, operations management, robot control, finance, epidemiology, scientific-experiment design, and tennis strategy, just to name a few.

Computing with spiders’ webs
Do spiders use their web as a computer? New research, led by the Universities of Bristol and Oxford, will look at spiders' webs to investigate their computational capabilities and based on this research they will develop new sensor technology to measure vibrations and flow. Spiders' webs have evolved over hundreds of millions of years and can be surprisingly complex.

Legacy of brilliant young scientist is a major leap in quantum computing
Researchers from the University of Bristol and Université Libre de Bruxelles have theoretically shown how to write programs for random circuitry in quantum computers. The breakthrough, published in the New Journal of Physics , is based on the work of first author, Dr Nick Russell, who tragically lost his life in a climbing accident last year.

Progress Towards a Circuit Diagram of the Brain
Precise knowledge of the connections in the brain - the links between all the nerve cells - is a prerequisite for better understanding this most complex of organs. Researchers from Heidelberg University have now developed a new algorithm - a computational procedure - that can extract this connectivity pattern with far greater precision than previously possible from microscopic images of the brain.

Study offers hope of new treatment for rheumatoid arthritis
One of the most feared and venomous arachnids in the world, the American brown recluse spider, has long been known for its signature necro-toxic venom, as well as its unusual silk. Now, a new Oxford University collaborative study offers an explanation for how the spider is able to make its silk so strong.
