Swirling liquids shed light on how bitcoin works
The physics involved with stirring a liquid operate the same way as the mathematical functions that secure digital information. This parallel could help in developing even more secure ways of protecting digital information. Fluid dynamics is not something that typically comes to mind when thinking about bitcoin.

For nuclear weapons reduction, a way to verify without revealing
In past negotiations aimed at reducing the arsenals of the world's nuclear superpowers, chiefly the U.S. and Russia, a major sticking point has been the verification process: How do you prove that real bombs and nuclear devices - not just replicas - have been destroyed, without revealing closely held secrets about the design of those weapons? Now, researchers at MIT have come up with a clever solution, which in effect serves as a physics-based version of the cryptographic keys used in computer encryption systems.

Extremely fast dives help peregrine falcons manoeuvre to catch agile prey
Using detailed computer simulations, Oxford University research has revealed why falcons dive at their prey using the same steering laws as man-made missiles. Published today in PLOS Computational Biology, researchers from Oxford's Department of Zoology use computer simulations of peregrine falcon attacks to show that the extreme speeds reached during dives from high altitudes enhance the raptors' ability to execute manoeuvres needed to successfully attack agile prey that would otherwise escape.

Researchers withdraw 2016 article
An academic paper involving University of Queensland authors has been retracted after the researchers found errors in the computer code used to analyse some of the data. The paper, titled "A mathematical model explains saturating axon guidance responses to molecular gradients", was published in the journal eLife on 2 February 2016.

New Engineering Project Aims to Create AI for UAVs
Drastic wing failure, as shown in the above illustration, would probably result in irreparable damage to an unmanned aerial vehicle. Learning must start and finish within a single execution. But, the newly proposed vehicle would have more than just sparse data at its disposal.

New technique more accurately reflects ponds on Arctic sea ice
This one simple mathematical trick can accurately predict the shape and melting effects of ponds on Arctic sea ice, according to new research by UChicago scientists. The study , published April 4 in Physical Review Letters by researchers with UChicago and MIT , should help climate scientists improve models of climate change and perhaps plug a gap between scientific predictions and observations over the past decade, they said.

CERN experiment analysed by Lancaster physicist sees hints of one of the rarest kaon decays
Scientists at Cern say their NA62 experiment has observed what may be an ultra-rare charged kaon decay. The NA62 experiment is a particle physics experiment at CERN using a 400 GeV proton beam from the SPS (Super Proton Synchrotron) accelerator. The UK has played a leading role in both the detector construction for NA62 and the data analysis and production of results, with Dr Giuseppe Ruggiero from Lancaster University as the Physics Coordinator.

Digital penicillin production
TU Wien and Sandoz GmbH have successfully implemented a real-time computer simulation of the complex growth behaviour of penicillin producing organisms. This simulation now helps to keep the production process under control. For thousands of years, micro-organisms have been used to facilitate chemical reactions - in beer brewing, for example.

Citizen science experiment predicts massive toll of flu pandemic on the UK
How fast could a new flu epidemic spread? The results of the UK's largest citizen science project of its kind ever attempted, carried out by thousands of volunteers, predict that 43 million people in the UK could be infected in an influenza pandemic, and with up to 886,000 of those infected expected to be fatalities.

COSMIC Impact: Next-Gen X-ray Microscopy Platform Now Operational
A next-generation X-ray beamline now operating at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) brings together a unique set of capabilities to measure the properties of materials at the nanoscale. Called COSMIC, for Coherent Scattering and Microscopy, this X-ray beamline at Berkeley Lab's Berkeley Lab's Advanced Light Source (ALS) allows scientists to probe working batteries and other active chemical reactions, and to reveal new details about magnetism and correlated electronic materials.

New model reveals forgotten influencers and ’sleeping beauties’ of science | UChicago News
For centuries, scientists and scholars have measured the influence of individuals and discoveries through citations, a crude statistic subject to biases, politics and other distortions. A new paper led by the Knowledge Lab at the University of Chicago describes a different way to keep score in science-a more direct measure of how influential ideas ripple out across scholarship and culture.

Scientists detect how words grow new meanings. Maybe computers will, too
What are voice-controlled personal assistants like Alexa and Siri to do when faced with words like "face” that have multiple meanings ranging from a body part to an action? Scientists from UC Berkeley, the University of Toronto and Lehigh University in Pennsylvania have begun to identify the algorithms humans have used over the last thousand years to give words new meanings.

Hairy tongues help bats drink up
Animals have evolved all manner of adaptations to get the nutrients they need. For nectar-feeding bats, long snouts and tongues let them dip in and out of flowers while hovering in mid-air. To help the cause, their tongues are covered in tiny hairs that serve as miniature spoons to scoop and drag up the tasty sap.

Novel computational biology model accurately describes dynamics of gene expression
Computational biologists have found a new way to accurately model certain forms of gene expression, including the body's 24-hour internal clock. In this study, we develop a simplifying method to reduce a class of commonly adopted gene expression models to a mathematical model, the PDMP, because it is easier to analyze and simulate than previous models.

Indian Sacred Texts and the Logic of Computer Ethics
Can we teach ethical behaviour to machines' Computer Scientists in Vienna are studying ancient Sanskrit texts and using the tools of mathematical logic to describe ethical rules. The Indian sacred texts of the Vedas have been studied for millennia. But now, for the first time in history, computer scientists in Vienna analyse them by applying the methods of mathematical logic.

Scientists get better numbers on what happens when electrons get wet
A new study paints a more accurate picture of how electrons behave after striking water, and how quickly they're snatched up in chemical reactions. There's a particular set of chemical reactions that governs many of the processes around us-everything from bridges corroding in water to your breakfast breaking down in your gut.

Location detection when GPS doesn’t work
With billions of GPS devices in use today, people are beginning to take it for granted that services on their handheld devices will be location-aware. But GPS doesn't work well indoors, and it's not precise enough for several potentially useful applications, such as locating medical equipment in hospitals or pallets of goods in warehouses, or helping emergency responders navigate unfamiliar buildings.

A ’STEM’ parent boosts girls’ participation in science degrees
ANN ARBOR-Even when girls perform just as well as boys on standardized math tests, they are half as likely to major in science at college. However, having one parent or guardian work in the STEM (science, technology, engineering or math) field makes it more likely for girls to perform better in math and to enroll in a "hard sciences" college degree in programs such as engineering, architecture, math and computer science.
