Cells engineered to produce insulin under the command of a smartphone helped keep blood sugar levels within normal limits in diabetic mice, a new study reports.
Two physicists have offered a way to mathematically describe a particular physics phenomenon called a phase transition in a system out of equilibrium. Such phenomena are central in physics, and understanding how they occur has been a long-held and vexing goal; their behavior and related effects are key to unlocking possibilities for new electronics and other next-generation technologies.
New two-dimensional quantum materials have been created with breakthrough electrical and magnetic attributes that could make them building blocks of future quantum computers and other advanced electronics. The researchers explored the physics behind the 2-D states of novel materials and determined they could push computers to new heights of speed and power.
Geckos are well known for effortlessly scrambling up walls and upside down across ceilings. Even in slippery rain forests, the lizards maintain their grip. Now scientists have created a double-sided adhesive that copies this reversible ability to stick and unstick to surfaces even in wet conditions. They say their development could be useful in underwater robotics, sensors and other bionic devices.
Deep Neural Networks are systems that are able to simulate human perception by 'memorizing' complex patterns on a mathematical level. One application for this is in the arts, where these systems are used for their creative potential. As DNN's become more popular, there is the danger of an unchecked proliferation of copyright protections, which risks stifling creativity. In order to prevent this, we should focus on the human element within the complex technological processes that engender automated art.
Scientists have developed a workflow management system that addresses irreproducibility when analyzing large genomics datasets with computers. Nextflow contributes to establishing good scientific practices and provides an important framework for those research projects where the analysis of large datasets are used to take decisions, for example, in precision medicine.
A new computer modeling study is aimed at making epidemiological models more accessible and useful for public-health collaborators and improving disease-related decision making.
Researchers are training artificial intelligence models to identify tuberculosis (TB) on chest X-rays, which may help screening and evaluation efforts in TB-prevalent areas with limited access to radiologists, according to a new study.
A new interface allows users to simply point and click on an item, then choose a grasp, to control a robot remotely.
Efforts to reduce our dependence on fossil fuels are advancing on various significant fronts. Initiatives include research focused on more efficient production of gaseous hydrogen fuel by using solar energy to break water down into components of hydrogen and oxygen. Scientists have now reported a key breakthrough in the basic science essential for progress toward this goal.
The ELO system, which most chess federations use today, ranks players by the results of their games. Although simple and efficient, it overlooks relevant criteria such as the quality of the moves players actually make. To overcome these limitations, Reseachers have now developed a new system.
A team of computer engineers and neurosurgeons, with an assist from Hollywood special effects experts, reports successful early tests of a novel, lifelike 3-D simulator designed to teach surgeons to perform a delicate, minimally invasive brain operation.
Last Friday, the first patient in the Netherlands received his click-on robotic arm. By means of a new technique, this robotic arm is clicked directly onto the bone. A unique characteristic of this prosthesis is that it can be controlled by the patient's own thoughts. Worldwide, there are only a handful of patients with such a prosthesis.
Scientists model the formation of multivalleys in semiconductor microcavities, bringing new ideas to the emerging valleytronics field.
Mathematical formulas that model how deadly mosquito-borne diseases spread can help medical researchers accurately predict how real-life outbreaks develop and find countermeasures, report scientists.
A new scientific discovery game called Mozak is allowing video gamers to significantly speed up reconstructing the intricate architecture of brain cells, a fundamental task in 21st century brain science. These citizen scientists have outperformed computers in tracing the intricate shapes of neurons, a first step in understanding how our brain circuitry works.
Inspired by 3-D printing, researchers explored development of one mechanical property called effective static compressibility. As they now report, by using a single cartridge it's possible to print a metamaterial which expands in size under hydrostatic pressure, even though it's made up of material which behaves normally under hydrostatic pressure -- that is, it shrinks. In principle, there is no limit to the negative value this material's effective compressibility can take.
Using an atomic quantum simulator, scientists have achieved the first-ever direct observation of chiral currents in the model topological insulator, the 2-D integer quantum Hall system.
The first large-scale study of recovery and resilience after a death in a friend group -- based on analysis of interactions in 15,000 anonymized networks on Facebook -- finds that when a friend dies, we get closer to that person's friends. The social network repairs itself in ways that keep our total connectedness the same.
Who hasn't lived through the frustrating experience of being without a phone after forgetting to recharge it? This could one day be a thing of the past thanks to technology under development.
