Diagnostics of genetic cardiac diseases using stem cell-derived cardiomyocytes

Tue, 06/19/2018 - 16:25
A new study demonstrates that with the use of artificial intelligence and machine learning, it is possible not only to accurately sort sick cardiac cell cultures from healthy ones, but also to differentiate between genetic cardiac diseases.

World's first intra-operative MRI-guided robot for bilateral stereotactic neurosurgery

Tue, 06/19/2018 - 16:25
Scientists have recently designed the first neurosurgical robotic system capable of performing bilateral stereotactic neurosurgery inside a magnetic resonance imaging ('MRI') scanner.

When photons spice up the energy levels of quantum particles

Tue, 06/19/2018 - 16:24
For the first time, a team of mathematical physicists, call upon supersymmetry to explain the behavior of particles that have received a photon and are subjected to particular potential energies known as shape-invariant potentials.

Future ultrahigh density data storage

Tue, 06/19/2018 - 16:24
The development of high-density data storage devices requires the highest possible density of elements in an array made up of individual nanomagnets. The closer they are together, the greater the magnetic interactions between them.

Approach can help English learners improve at math word problems

Tue, 06/19/2018 - 16:24
Education professors have shown that a comprehension-based strategy can help English learners improve their math word-problem solving abilities. The approach boosts reading comprehension and problem solving as well.

Nuclear power shutdowns won't spike power prices

Tue, 06/19/2018 - 16:24
Despite economic woes that could shutter two of Pennsylvania's nuclear power plants -- which generate 6 percent of the state's power -- power prices will remain steady due to low natural gas prices, according to an associate professor of energy policy and economics.

Spintronics: Controlling magnetic spin with electric fields

Tue, 06/19/2018 - 16:24
Physicists have found a way to reverse electron spins using electric fields for the first time, paving the way for programmable spintronics technologies.

Targeting the engine room of the cancer cell

Mon, 06/18/2018 - 18:18
Researchers have developed a highly innovative computational framework that can support personalized cancer treatment by matching individual tumors with the drugs or drug combinations that are most likely to kill them.

Algorithm speeds up process for analyzing 3D medical images

Mon, 06/18/2018 - 15:27
Researchers describe a machine-learning algorithm that can register brain scans and other 3D images more than 1,000 times more quickly using novel learning techniques.

Virtual reality headsets significantly reduce children's fear of needles

Mon, 06/18/2018 - 14:26
Almost anyone can relate to being afraid of needles and injections. A pilot study is the first to use a 3D virtual reality headset to test this tool as a distraction method in a pediatric setting. Children were given the choice of a roller coaster ride, helicopter ride or a hot-air balloon ride. Results show that anticipated versus actual pain and fear were reduced in 94.1 percent of the pediatric study subjects.

Better be safe than sorry: Economic optimization risks tipping of Earth system elements

Fri, 06/15/2018 - 19:44
Optimizing economic welfare without constraints might put human well-being at risk, a new climate study argues. While being successful in bringing down costs of greenhouse gas reductions for instance, the concept of profit maximization alone does not suffice to avoid the tipping of critical elements in the Earth system which could lead to dramatic changes of our lifelihood. The scientists use mathematical experiments to compare economic optimization to the governance concepts of sustainability and the more recent approach of a safe operating space for humanity. All of these turn out to have their benefits and deficits, yet the profit-maximizing approach shows the greatest likelihood of producing outcomes that harm people or the environment.

Study finds less corruption in countries where more women are in government

Fri, 06/15/2018 - 13:48
The new research is the most comprehensive study on this topic and looks at the implications of the presence of women in other occupations as including the shares of women in the labor force, clerical positions, and decision making positions such as the CEOs and other managerial positions.

Novel method for investigating pore geometry in rocks

Fri, 06/15/2018 - 13:48
In a fusion of mathematics and earth science, researchers have proposed a novel method for characterizing pore geometry in rock, based on persistence diagram analysis and a newly proposed parameter, the distance parameter H. The method represents heterogeneity and differences in rock type more effectively than the conventional method based on velocity distribution, without requiring costly numerical flow simulations, and the results are relatively stable with small changes in pore space.

This is what a stretchy circuit looks like

Fri, 06/15/2018 - 01:38
Researchers have made a new hybrid conductive material -- part elastic polymer, part liquid metal -- that can be bent and stretched at will. Circuits made with this material can take most two-dimensional shapes and are also non-toxic.

AI-driven ultrafast technology visually identifies cells without images

Fri, 06/15/2018 - 01:38
A team made of a scientific start-up company and academic researchers has invented a new cell identification and sorting system called Ghost Cytometry. The system combines a novel imaging technique with artificial intelligence to identify and sort cells with unprecedented high-throughput speed. The scientists leading the project hope that their method will be used to identify and sort cancer cells circulating in patients' blood, enable faster drug discovery, and improve the quality of cell-based medicine.

Human and artificial intelligence join forces to study complexity of the brain

Fri, 06/15/2018 - 01:37
A team of scientists has mapped the gene expression of each individual brain cell during aging, though they started small: with the brain of a fruit fly. Their 'cell atlas' provides unprecedented insights into the workings of the brain as it ages.

Quantum transfer at the push of a button

Fri, 06/15/2018 - 01:37
In the new quantum information technologies, fragile quantum states have to be transferred between distant quantum bits. Researchers have now realized such a quantum transmission between two solid-state qubits at the push of a button.

System allows surveillance cameras to 'talk' to the public through individual smartphones

Fri, 06/15/2018 - 01:29
Researchers have created a technology that allows public cameras to send personalized messages to people without compromising their privacy. The team developed a real-time end-to-end system called PHADE to allow this process, known as private human addressing.

Network theory links behavioral information flow with contained epidemic outbreaks

Fri, 06/15/2018 - 01:26
Over the last two decades, large-scale outbreaks of infectious diseases have resulted in high levels of morbidity, mortality, and overall economic burden for affected regions. As complex networks become increasingly popular tools of study, researchers are applying network theory to the field of epidemiology. Researchers now employ a concrete interplay model in quenched multiplex networks to study the connection between adaptive human behavior and epidemic spread.

Magnetic 3D-printed structures crawl, roll, and jump

Wed, 06/13/2018 - 20:30
Engineers have created soft, 3D-printed structures whose movements can be controlled with a wave of a magnet, much like marionettes without the strings. The menagerie of structures that can be magnetically manipulated includes a smooth ring that wrinkles up, a long tube that squeezes shut, a sheet that folds itself, and a spider-like 'grabber' that can crawl, roll, jump, and snap together fast enough to catch a passing ball.
