For software programmers, security tools are analytic software that can scan or run their code to expose vulnerabilities long before the software goes to market. But these tools can have shortcomings, and programmers don't always use them. New research tackles three different aspects of the issue.
Like the Rubik's Cube, a three-dimensional combination puzzle where every twist also scrambles the face opposite of it, economics puzzles are similarly interlinked -- a change in policy may lead to repercussions elsewhere.
Using computer vision, signal processing and privacy protection, a doctoral student, along with electrical and computer engineering professors, have developed "MEBook," a combination of a social narrative and gaming system that psychologists and parents can use as behavioral therapies for autistic children.
An automated speech analysis program correctly differentiated between at-risk young people who developed psychosis over a two-and-a-half year period and those who did not. In a proof-of-principle study, researchers found that the computerized analysis provided a more accurate classification than clinical ratings.
By minimizing the acceleration of industrial robots, energy consumption can be reduced by up to 40 percent -- while retaining the given production time. This is the result of a new optimization algorithm.
With a new design that sandwiches a polar metallic oxide between insulating materials at the nanoscale, the resulting multiferroic superlattice could open the door for improved electronics.
A professor has made the 'magic' sphere for information transfer. In several years our computers, nanoantennas and other kinds of equipment will operate on the base of photons, rather than electrons. Even now we are practically prepared to accomplish this switch. If it happens, the spheres may become one of the elementary components of new photonic devices.
An interdisciplinary group of researchers report on nanofibers, which enable for the first time a directed energy transport over several micrometers at room temperature. This transport distance can only be explained with quantum coherence effects along the individual nanofibers.
With the globalization of biomedical research and growing concerns about possible pandemics of diseases such as HIV, SARS, and Ebola, international data-sharing practices are of growing interest to the biomedical science community. A new special journal issue presents guidelines, protocols, models, and new resources to improve data sharing across the globe.
A new model presents a common mathematical structure that underlies the full range of feeding strategies of plants and animals: from familiar parasites, predators, and scavengers to more obscure parasitic castrators and decomposers. Now ecologists can view all food-web interactions through the same lens using a common language to understand the natural world.
Tracking mobile phone data is often associated with privacy issues, but these vast datasets could be the key to understanding how infectious diseases are spread seasonally, according to a study.
Newly developed 2-D crystals are capable of delivering designer materials with revolutionary new properties. By protecting the new reactive crystals with more stable 2D materials, such as graphene, via computer control in a specially designed inert gas chamber environments, these materials can be successfully isolated to a single atomic layer for the first time.
Security and safety could be improved if researchers from very disparate disciplines - humanities, computer science and politics - were to work together, according to new research. Moreover, such coordinated efforts online would improve crisis management during natural disasters, terrorist attack or cyber warfare.
New software could speed up breast cancer diagnosis with 90 percent accuracy without the need for a specialist, according to research. This could improve breast cancer management, particularly in developing countries where pathologists are not routinely available.
Activity trackers can provide a good overall estimate of calories burned, but a new study finds they're less accurate when measuring certain activities, such as strength training.
New supercomputer models have come closer than ever to capturing the behavior of normal human heart valves and their replacements, according to recent studies. The studies focused on how heart valve tissue responds to realistic blood flow. The new models can help doctors make more durable repair and replacement of heart valves.
Researchers have developed an efficient algorithm that can interpret the wheezing of patients with breathing difficulties to give medical providers information about what's happening in the lungs. The work is part of a larger, ongoing project to develop wearable smart medical sensors for monitoring, collecting and interpreting personal health data.
A new study analyzes the opinions of 109 clinicians asking them whether video games are a problem for society. The older the clinician, the more likely they are to think playing video games leads to violent behavior, investigators report.
Steel is one of the main building blocks of modern society. This is because of all the metallic materials, steel - which is mainly iron – is the most advantageous to produce from both an economic and environmental point of view. Also, steel is extremely versatile: there are thousands of steels with properties suited to all kinds of applications. For these reasons, steel is used more than all other metals together. Because so much steel is used globally, by learning to make and use steels in a more optimal way, we can help make considerable improvements to the use of the planet’s raw materials and energy, and greenhouse gas production. By combining mathematics and materials science, we can help this happen.
New research could one day help build computers from DNA. Scientists have found a way to 'switch' the structure of DNA using copper salts and EDTA (Ethylenediaminetetraacetic acid) -- an agent commonly found in shampoo and other household products. The applications for this discovery include nanotechnology -- where DNA is used to make tiny machines, and in DNA-based computing -- where computers are built from DNA rather than silicon.
