Researchers have a better way to predict flight delays

Mon, 11/14/2016 - 15:39
Researchers have devised a new computer model that can more accurately predict delays faster than anything currently in use.

3D printing: Customized insoles for diabetes patients

Mon, 11/14/2016 - 13:22
In the past, insoles for patients with diabetes were hand-made by orthopedic shoemakers. In the future, these specialist shoemakers will be able to produce insoles more cost-effectively thanks to new software and the use of 3D printers. This approach means the mechanical properties of each insole can be assessed scientifically and more effectively.

Researchers found mathematical structure that was thought not to exist

Mon, 11/14/2016 - 13:19
Researchers found mathematical structure that was thought not to exist. The best possible q-analogs of codes may be useful in more efficient data transmission.

Even physicists are 'afraid' of mathematics

Fri, 11/11/2016 - 18:21
Physicists avoid highly mathematical work despite being trained in advanced mathematics, new research suggests.

Using pectin to advance neuron-like electronic systems

Fri, 11/11/2016 - 14:47
A team of scientists have used pectin with a high degree of methylation as the medium to create a new architecture of hybrid device with a double-layered polyelectrolyte that alone drives memristive behavior.

Breakthrough in the quantum transfer of information between matter and light

Fri, 11/11/2016 - 02:27
From stationary to flying qubits at speeds never reached before…. This feat brings us a little closer to the era when information is transmitted via quantum principles.

Increased smartphone screen-time associated with lower sleep quality

Thu, 11/10/2016 - 20:50
Exposure to smartphone screens is associated with lower sleep quality, according to a study that used a smartphone app to record the daily screen-time of over 650 adults.

Insect vector feeding recognized by machine learning

Thu, 11/10/2016 - 20:32
Scientists have used machine learning algorithms to teach computers to recognize the insect feeding patterns involved in pathogen transmission. The study also uncovers plant traits that might lead to the disruption of pathogen transmission and enable advances in agriculture, livestock and human health.

Stable quantum bits can be made from complex molecules

Thu, 11/10/2016 - 20:30
Quantum computing is about to get more complex. Researchers have evidence that large molecules made of nickel and chromium can store and process information in the same way bytes do for digital computers. The researchers present algorithms proving it's possible to use supramolecular chemistry to connect "qubits," the basic units for quantum information processing. This approach would generate several kinds of stable qubits that could be connected together into structures called "two-qubit gates."

Precaution, governance of emerging technologies

Thu, 11/10/2016 - 20:10
Precautionary approaches to governance of emerging technology, which call for constraints on the use of technology whose potential harms and other outcomes are highly uncertain, are often criticized for reflecting "risk panics," but precaution can be consistent with support for science, concludes an article.

Simulations show swirling rings, whirlpool-like structure in subatomic 'soup'

Thu, 11/10/2016 - 18:20
Powerful supercomputer simulations of high-energy collisions between atomic cores provide new insights about the complex structure of a superhot fluid called the quark-gluon plasma.

Artificial-intelligence system surfs web to improve its performance

Thu, 11/10/2016 - 17:02
Of the vast wealth of information unlocked by the Internet, most is plain text. The data necessary to answer myriad questions -- about, say, the correlations between the industrial use of certain chemicals and incidents of disease, or between patterns of news coverage and voter-poll results -- may all be online. But extracting it from plain text and organizing it for quantitative analysis may be prohibitively time consuming.

HIV test performed on USB stick

Thu, 11/10/2016 - 13:40
A new device uses a drop of blood to detect HIV, and then creates an electrical signal that can be read by a computer, laptop or handheld device.

Accelerating cancer research with deep learning

Wed, 11/09/2016 - 23:28
Despite steady progress in detection and treatment in recent decades, cancer remains the second leading cause of death in the United States, cutting short the lives of approximately 500,000 people each year. A research team has focused on creating software that can quickly identify valuable information in cancer reports, an ability that would not only save time and worker hours but also potentially reveal overlooked avenues in cancer research.

Probable scientific misconduct in bone health studies, new study suggests

Wed, 11/09/2016 - 23:19
A new study suggests probable scientific misconduct in at least some of 33 bone health trials published in various medical journals. The study used statistical methods to detect scientific misconduct or research fraud and calls into question the validity of a body of research work led mainly by one researcher in Japan.

Leg movement restored in primates using wireless neural interface

Wed, 11/09/2016 - 18:31
An international team of scientists has used a wireless "brain-spinal interface" to bypass spinal cord injuries in a pair of rhesus macaques, restoring intentional walking movement to a temporarily paralyzed leg. The researchers say this is the first time a neural prosthetic has been used to restore walking movement directly to the legs of nonhuman primates.

Computers made of genetic material?

Wed, 11/09/2016 - 16:33
Tinier than the AIDS virus -- that is currently the circumference of the smallest transistors. The industry has shrunk the central elements of their computer chips to fourteen nanometers in the last sixty years. Conventional methods, however, are hitting physical boundaries. Researchers around the world are looking for alternatives. One method could be the self-organization of complex components from molecules and atoms. Scientists have now made an important advance: the physicists conducted a current through gold-plated nanowires, which independently assembled themselves from single DNA strands.

'Bottlebrush' polymers make dielectric elastomers increasingly viable for use in devices

Wed, 11/09/2016 - 16:28
A multi-institutional research team has developed a new electroactive polymer material that can change shape and size when exposed to a relatively small electric field. The advance overcomes two longstanding challenges regarding the use of electroactive polymers to develop new devices, opening the door to a suite of applications ranging from microrobotics to designer haptic, optic, microfluidic and wearable technologies.

Now you see it, now you don't: Invisibility cloak for high-tech processing chips

Wed, 11/09/2016 - 14:10
A cloaking device for microscopic photonics integrated devices has now been created in an effort to make future processing chips smaller, faster and consume less power.

New approach predicts price trends in the stock options market
