Troy, N.Y. -- While simulation platforms have been used to train surgeons before they enter an actual operating room (OR), few studies have evaluated how well trainees transfer those skills from the simulator to the OR. Now, a study led by Rensselaer Polytechnic Institute that used noninvasive brain imaging to evaluate brain activity has found that simulator-trained medical students successfully transferred those skills to operating on cadavers and were faster than peers who had no simulator training.
Researchers at Dartmouth, Stanford University, and IBM Research, conducted a critical review of existing literature to determine whether social media big data can be used to understand communication and behavioral patterns related to prescription drug abuse. Their study found that with proper research methods and attention to privacy and ethical issues, social media big data can reveal important information concerning drug abuse, such as user-reported side effects, drug cravings, emotional states, and risky behaviors.
ARLINGTON, Va.--To better protect warfighters during live-fire training, the Office of Naval Research's (ONR) TechSolutions program has sponsored the development of a new Google Maps-style software tool to map out training areas in great detail.
(BOSTON) -- Synthetic biologists are fitting the genomes of microorganisms with synthetic gene circuits to break down polluting plastics, non-invasively diagnose and treat infections in the human gut, and generate chemicals and nutrition on long haul space flights. Although showing great promise in the laboratory, these technologies require control and safety measures that make sure the engineered microorganisms keep their functional gene circuits intact over many cell divisions, and that they are contained to the specific environments they are designed for.
HOUSTON - (Nov. 16, 2017) - Rice University engineers are using 3-D printers to turn structures that have until now existed primarily in theory into strong, light and durable materials with complex, repeating patterns.
The porous structures called schwarzites are designed with computer algorithms, but Rice researchers found they could send data from the programs to printers and make macroscale, polymer models for testing. Their samples strive to use as little material as possible and still provide strength and compressibility.
Researchers from North Carolina State University have found that diffusion plays an unexpected role in cell differentiation during the early stages of development in the embryos of Drosophila, or fruit flies. Instead of spreading a molecular signal out, it was found that diffusion, facilitated through a carrier molecule, actually concentrates the signal in one place. This "facilitated diffusion" mechanism has previously been found in other systems, and the new finding indicates it may be more widespread than previously thought.
New Rochelle, NY, November 16, 2017--With what strategies should developing countries invest in for emerging biotechnologies and precision medicine? This timely question on biotechnology global development was discussed in an innovation analysis published in OMICS: A Journal of Integrative Biology. The analysis, co-authored by Vural Özdemir, MD, PhD, DABCP (Toronto, Canada) and George P. Patrinos (Patras, Greece), notes that an "astutely global, and yet customized strategy for applications of omics and biotechnology innovations across countries and populations is sorely missing.
London, Nov. 16, 2017 - Neanderthals survived at least 3,000 years longer than we thought in Southern Iberia - what is now Spain - long after they had died out everywhere else, according to new research published in Heliyon.
A new technique devised by researchers from North Carolina State University and the University of Calgary provides a more in-depth look at the composition of and activity within microbial communities - the microscopic life within our bodies and all around us.
The glaciers that carved Yosemite Valley left highly polished surfaces on many of the region's rock formations. These smooth, shiny surfaces, known as glacial polish, are common in the Sierra Nevada and other glaciated landscapes.
