UTA engineer working to develop bioinks for use in 3-D printing of tissues, organs

( University of Texas at Arlington) Kyungsuk Yum, an assistant professor in the Materials Science and Engineering Department of UTA's College of Engineering, has earned a $100,000 grant from the National Science Foundation to develop nanocomposite hydrogel bioinks that could be used for that purpose.

Super cement's secret

( DOE/Pacific Northwest National Laboratory) Mayenite is one smart cement -- it can be turned from an insulator to a transparent conductor and back. It is also suitable for use as semiconductors in flat panel displays. The secret behind mayenite's magic is a tiny change in its chemical composition. In new work in Proceedings of the National Academy of Sciences, researchers show how components called electron anions help to transform crystalline mayenite, also called C12A7, into semiconducting glass.

Purest yet liver-like cells generated from induced pluripotent stem cells

( Medical University of South Carolina) A team of researchers from the Medical University of South Carolina and elsewhere has found a better way to purify liver cells made from induced pluripotent stem cells. This new methodology could facilitate progress toward an important clinical goal: the treatment of patients with disease-causing mutations in their livers by transplant of unmutated liver cells derived from their own stem cells.

3-D printed tool for building aircraft achieves Guinness World Records title

( DOE/Oak Ridge National Laboratory) A 3-D printed trim-and-drill tool, developed by researchers at the Department of Energy's Oak Ridge National Laboratory to be evaluated at The Boeing Company, has received the title of largest solid 3-D printed item by Guinness World Records™.

NASA sees Typhoon Lionrock approaching Japan

( NASA/Goddard Space Flight Center) Tropical Storm Lionrock continued crawling toward the main island of Honshu, Japan, as NASA's Aqua and NASA-NOAA's Suomi NPP satellites passed overhead and gathered data on the storm.

NASA spots Central Pacific's Madeline strengthening into a hurricane

( NASA/Goddard Space Flight Center) As Hurricane Lester in the Eastern Pacific Ocean strengthened into a major hurricane, Tropical Storm Madeline in the Central Pacific became a hurricane. NASA-NOAA's Suomi NPP satellite captured an image as Madeline was transitioning and organizing.

NASA peers into Tropical Depression 9 in the Gulf of Mexico

( NASA/Goddard Space Flight Center) The Global Precipitation Measurement mission or GPM core satellite analyzed Tropical Depression 9 after formed in the Gulf of Mexico after a slow crawl over the last week.

How machine learning can help with voice disorders

( Massachusetts Institute of Technology, CSAIL ) A team from MIT's Computer Science and Artificial Intelligence Laboratory and Massachusetts General Hospital has developed a wearable device that can tell if a user is misusing their voice and potentially someday be used to help detect vocal disorders.

Simple equation predicts force needed to push objects through sand

( Massachusetts Institute of Technology) For those of you who take sandcastle building very seriously, listen up: MIT engineers now say you can trust a very simple equation to calculate the force required to push a shovel -- and any other 'intruder' -- through sand. The team also found that the same concept, known as the resistive force theory, can generate useful equations for cohesive materials like muds.

University of Akron researchers find thin layers of water can become ice-like at room temperature

( University of Akron) New research by scientists at The University of Akron shows that a nanometer-thin layer of water between two charged surfaces exhibits ice-like tendencies that allow it to withstand pressures of hundreds of atmospheres. The discovery could lead to better ways to minimize friction in a variety of settings
