A research team reports that researchers and practitioners share more interests than either group realizes and outlines ways that the two groups can collaborate more effectively -- and it involves changing how business schools do business.
A new method for analyzing the scrambled genomes of cancer cells gives researchers for the first time the ability to simultaneously identify two different types of genetic changes associated with cancers and to identify connections between the two.
Normally computers speed up calculations. But with his new pen-and-paper formula, a researcher gets his results thousands of times faster than using conventional computer codes. The astrophysicist calculates the abundances of molecules (known as atmospheric chemistry) in exoplanetary atmospheres. Ultimately, deciphering the abundances of molecules allows us to interpret if features in a spectrum are due to physics, geology or biology.
A new neuroimaging study reveals the mental stages people go through as they are solving challenging math problems. Insights from this new work may eventually be applied to the design of more effective classroom instruction - particularly in the form of improving cognitive tutors by creating models that match the brain activation and thinking patterns used to solve these problems, say investigators.
Materials researchers have developed a way to integrate novel functional materials onto a computer chip, allowing the creation of new smart devices and systems.
Researchers have developed self-guided quantum tomography which uses a search algorithm to iteratively "find" the quantum state.This technique significantly reduces the necessary resources by removing the need for any data storage or post-processing.
Scientists have successfully demonstrated the self-organizing pattern formation in active materials at microscale with computer simulations.
Iron Man's suit. Captain America's shield. The Batmobile. These all could look a lot more realistic thanks to a new algorithm developed by a team of computer graphics experts. The researchers has created a method to improve how computer graphics software reproduces the way light interacts with extremely small details, called glints, on the surface of a wide range of materials.
Device architecture that can tune a material’s magnetic properties could reduce the power consumption of memories.
Physicists have discovered that the timing of electronic orders on the stock market can be mathematically described in the same way as the lifetime of a light bulb.
As online dating has become a widely accepted way to attract possible romantic partners, scholars have been taking a closer look at the practice. What makes an online dater successful? Do the same factors that make face-to-face relationships successful also apply in the online dating world?
Inside the human body, the same drug can interact with multiple molecules. This phenomenon is known as 'polypharmacology' and, according to the interaction, a drug can cure a disease or cause side effects in the patient. It is therefore critical to create a drug that can hit the right molecular target, minimizing the risk of undesired molecular interactions. The current process to screen for this is time consuming and expensive. systemsDock is a new, free on-line resource that makes screening for drugs faster and more accurate.
For the first time, researchers have crossed the 'break even' point in preserving a bit of quantum information for longer than the lifetime of its constituent parts. They have created a novel system to encode, spot errors, decode, and correct errors in a quantum bit, also known as a 'qubit.' The development of such a robust method of Quantum Error Correction has been one of the biggest remaining hurdles in quantum computation.
Social robots can be used in the educational or health system, where they would support trainers and therapists in their work. The robots can be programmed to practice vocabulary with children or to make rehabilitation exercises with stroke patients.
Getting fit and athletic -- while sitting? Researchers are developing an active chair. At first glance, the chair looks just like another other reclining chair with a footrest you would find in a living room in front of the TV. But upon closer inspection, the chair is actually connected to a virtual avatar and has all manner of technical refinements.
Resistive random-access memory that avoids an initial forming process improves fabrication methods and reliability.
Open air is getting crowded. Signals streaming back and forth from smart devices stretch existing fourth-generation wireless networks almost to their limits. As demands on these systems increase, engineers aim to open new frontiers in cutting-edge wireless communications to develop the next generation of wireless technologies.
A new study helps to shed light on the transcriptomic differences between different tissues in Arabidopsis, an important model organism, by creating a standardized "atlas" that can automatically annotate samples to include lost metadata such as tissue type.
Why do we feel good about giving to charity when there is no direct benefit to ourselves, and feel bad about cheating the system? Mathematicians may have found an answer to the longstanding puzzle as to why we have evolved to cooperate.
When scaling down robots to the micrometer scale for tiny tasks such as incising tissue and puncturing retinal veins, minimalism is key. To make smaller, simpler microrobots, researchers have developed a fabrication method which utilizes the minimum geometric requirements for fluid motion -- consisting of just two conjoined microparticles coated with bits of magnetic debris.
