Swimming microbes steer themselves into mathematical order
For News Media FOR IMMEDIATE RELEASE × A sheet of tiny swimming organisms that "push" themselves through fluid with, say, flagella, create forces in the liquid that bend the sheet in asymmetric, shrinking folds. Image courtesy of Saverio Spagnolie Freeing thousands of microorganisms to swim in random directions in an infinite pool of liquid may not sound like a recipe for order, but eventually the swarm will go with its own flow.

Securing the
Securing the "internet of things" in the quantum age
Efficient chip enables low-power devices to run today's toughest quantum encryption schemes. MIT researchers have developed a novel cryptography circuit that can be used to protect low-power "internet of things" (IoT) devices in the coming age of quantum computing. Quantum computers can in principle execute calculations that today are practically impossible for classical computers.

True colours: a test to determine how animals see colour
True colours: a test to determine how animals see colour
Trained fish at The University of Queensland are helping researchers understand animal vision and factors behind the huge variation in colours between and among species. Ms Naomi Green and Dr Karen Cheney from the Queensland Brain Institute and the School of Biological Sciences have devised what they believe to be the most thorough test of vertebrate colour perception ever developed.

Democratizing data science
Democratizing data science
Tool for nonstatisticians automatically generates models that glean insights from complex datasets. MIT researchers are hoping to advance the democratization of data science with a new tool for nonstatisticians that automatically generates models for analyzing raw data. Democratizing data science is the notion that anyone, with little to no expertise, can do data science if provided ample data and user-friendly analytics tools.

Census data could be used to improve city neighbourhoods
A new analysis of the 2011 census has revealed that social differences among city populations significantly influence how neighbourhoods take shape. Researchers hope that their insights could help councils to make better planning decisions. Dr Thilo Gross and Dr Edmund Barter in the Department of Engineering Mathematics at the University of Bristol, used a new algorithm to gain insight into city neighbourhood characteristics, starting with Bristol.

Customizing computer-aided design
System breaks down complex designs into easily modifiable shapes for custom manufacturing and 3-D printing. MIT researchers have devised a technique that "reverse engineers" complex 3-D computer-aided design (CAD) models, making them far easier for users to customize for manufacturing and 3-D printing applications.

Deep-learning technique reveals "invisible" objects in the dark
Method could illuminate features of biological tissues in low-exposure images. Small imperfections in a wine glass or tiny creases in a contact lens can be tricky to make out, even in good light. In almost total darkness, images of such transparent features or objects are nearly impossible to decipher.

There’s real skill in fantasy sports
Researchers find most fantasy sports are based on skill, not luck. If you've ever taken part in the armchair sport of fantasy football and found yourself at the top of your league's standings at the end of the season, a new MIT study suggests your performance - however far removed from any actual playing field - was likely based on skill rather than luck.

For new HPV DNA test, study finds there may be little benefit in screening women aged 55 with a negative test
Regular cytology screening (pap or smear test) is still the most commonly used HPV screening method, and can prevent cancers up to age 75 years, although benefits decline with age For the newly introduced HPV DNA test, which offers a higher degree of accuracy, women aged 55 who have a negative test were predicted to be at low risk of cervical cancer  A single negative human papillomavirus (HPV) DNA test - a newly introduced test which can detect

Model paves way for faster, more efficient translations of more languages
Model paves way for faster, more efficient translations of more languages
New system may open up the world's roughly 7,000 spoken languages to computer-based translation. MIT researchers have developed a novel "unsupervised" language translation model - meaning it runs without the need for human annotations and guidance - that could lead to faster, more efficient computer-based translations of far more languages.

Cryptographic protocol enables greater collaboration in drug discovery
Cryptographic protocol enables greater collaboration in drug discovery
Neural network that securely finds potential drugs could encourage large-scale pooling of sensitive data. MIT researchers have developed a cryptographic system that could help neural networks identify promising drug candidates in massive pharmacological datasets, while keeping the data private. Secure computation done at such a massive scale could enable broad pooling of sensitive pharmacological data for predictive drug discovery.

Technique quickly identifies extreme event statistics
Technique quickly identifies extreme event statistics
Machine-learning model provides risk assessment for complex nonlinear systems, including boats and offshore platforms. Seafaring vessels and offshore platforms endure a constant battery of waves and currents. Over decades of operation, these structures can, without warning, meet head-on with a rogue wave, freak storm, or some other extreme event, with potentially damaging consequences.

Researcher Thinks Outside the Box for Big Science
"What would happen if...'" To answer that question, scientists - whether they're studying climate science or cosmology - rely on computer simulations to bring their abstract data to life in 3D. The process is painstakingly slow, however: One simulation can take up to a million CPU (central processing unit) hours on a supercomputer.

Smoothing out sketches’ rough edges
MIT-developed tool improves automated image vectorization, saving digital artists time and effort. Artists may soon have at their disposal a new MIT-developed tool that could help them create digital characters, logos, and other graphics more quickly and easily.  Many digital artists rely on image vectorization, a technique that converts a pixel-based image into an image comprising groupings of clearly defined shapes.

Pioneering work: mathematical fundamentals of light refraction: Münster mathematician's research into wave propagation in complex materials
Pioneering work: mathematical fundamentals of light refraction: Münster mathematician’s research into wave propagation in complex materials
Something everyone learns in Physics lessons at school is that light is refracted and reflected at the interface between air and water. The reason for this is the different refractive indices which the two mediums have - an optical property which is characteristic of each material. There are also materials with so-called negative refraction indices.

String Art - from the Hand of a Robot
String Art - from the Hand of a Robot
String art is a technique for the creation of visual artwork where images emerge from a set of strings that are spanned between pins. Now, at TU Wien (Vienna) this work can be delegated to a robot - an example of a complex task that digital fabrication can solve. The basic idea of string art is simple: hooks distributed on a frame are connected by strings back and forth until they fuse to a perceptible image.

Universities "must look deeper" into the drivers of inequality within research
Universities must seek a deeper understanding of the drivers of inequality in job roles and academic ranks if they are to achieve change. Professor Axel Gandy (Chair in Statistics, Imperial College London), Dr Georg Hahn (Senior Research Associate in the Department of Mathematics and Statistics at Lancaster University) and Professor Nick Jennings (Vice Provost for Research at Imperial College London) have looked at possible inequalities relating to grant application success rates within Imperial over a five-year period.

MIT mathematicians solve age-old spaghetti mystery
MIT mathematicians solve age-old spaghetti mystery
It's nearly impossible to break a dry spaghetti noodle into only two pieces. A new MIT study shows how and why it can be done. If you happen to have a box of spaghetti in your pantry, try this experiment: Pull out a single spaghetti stick and hold it at both ends. Now bend it until it breaks. How many fragments did you make? If the answer is three or more, pull out another stick and try again.
