Placenta-on-a-chip

Mon, 07/25/2016 - 19:11
Researchers have developed the first placenta-on-a-chip that can fully model the transport of nutrients across the placental barrier. The flash-drive-sized device contains two layers of human cells that model the interface between mother and fetus.

Sub-set of stem cells found to minimize risks when used to treat damaged hearts

Mon, 07/25/2016 - 19:11
Scientists use mathematical modeling to simulate human mesenchymal stem cell delivery to a damaged heart and found that using one sub-set of these stem cells minimizes the risks associated with this therapy. The study represents a development in novel strategies to repair and regenerate heart muscle and could improve stem cell treatments for heart attack patients.

Ultra-flat circuits will have unique properties

Mon, 07/25/2016 - 17:37
Theoretical physicists have analyzed the electronic consequences of creating circuits in two dimensions by simulating the juxtaposition of different atom-thick materials like graphene and hexagonal boron nitride.

New robot overcomes obstacles

Mon, 07/25/2016 - 16:20
It looks like a bicycle chain, but has just twelve segments about the size of a fist. In each segment there is a motor. This describes pretty much the robot developed by the four bachelor students in Computer Engineering.

New movie screen allows for glasses-free 3-D

Mon, 07/25/2016 - 16:18
Researchers have demonstrated a display that lets you watch 3-D films in a movie theater without extra eyewear. Dubbed 'Cinema 3D,' the prototype uses a special array of lenses and mirrors to enable viewers to watch a 3-D movie from any seat in a theater.

Medical students using electronic health records to track former patients

Mon, 07/25/2016 - 16:17
Many medical students are using electronic health records (EHRs) to track former patients but the practice, which students report as being educational, raises some ethical questions, according to an article.

Twitter sentiment offers clues to stock performance, study shows

Mon, 07/25/2016 - 15:15
A strong contemporaneous correlation does exist between the mood of a day’s worth of tweets about a particular stock and the performance of that stock, research shows.

Flower bud uniformity beholden to time, space

Mon, 07/25/2016 - 14:52
A study of sepals in Arabidopsis plants reveals the mystery of how uniformity in flowers and organs occurs. In the study, the diverse international team used an interdisciplinary approach that combined expertise in biology, computer science, physics and applied mathematics.

Pokémon Go could ease Type 2 diabetes burden

Mon, 07/25/2016 - 13:01
Millions of people around the world have started to play Pokémon Go, a virtual reality treasure hunt where players must walk to places within the real world and catch, train and battle monsters which appear on their mobile phone screens. Leading diabetes researchers believe the craze of Pokémon Go could be an “innovative solution” to rising obesity levels and chronic disease.

Trolls often waive their anonymity online

Mon, 07/25/2016 - 13:01
Hate speech in social media can damage or even destroy the reputation of an individual or a company very quickly. Widespread opinion blames the fact that individuals generally write these things anonymously online as the reason for these posts. A research project has now shown, however, that trolls are increasingly using their full name online. As a result, a ban on anonymity will likely fail to prevent the feared firestorms but possibly aggravate them even more.

Physicists discover a new approach for building quantum computers

Fri, 07/22/2016 - 14:41
The main reason why quantum computers are so hard to manufacture is that now scientists still haven't find a simple way to control complex systems of qubits. This research discovers a different approach:Instead of uniting multiple two-state systems into one, authors use one system with multiple states. This approach proves to be more effiective, since it is easier to make a stable multi-level system, than to maintain stability in a complex system.

New remote-controlled microrobots for medical operations

Fri, 07/22/2016 - 14:41
Scientists have developed a new method for building microrobots that could be used in the body to deliver drugs and perform other medical operations.

Hey robot, shimmy like a centipede

Fri, 07/22/2016 - 13:29
Researchers have used computer simulations and robotics to uncover a surprising insight into the mechanics of locomotion, namely that taming instability -- a factor that might be a disadvantage -- is a key to the centipede's success.

Collective hum: Buzzing midges inspire new swarm theory

Fri, 07/22/2016 - 01:09
A team of researchers based in Israel and the US has found a mathematical resemblance between swarm dynamics and gravitational interactions. The study could provide a big leap forward in understanding the mass movement of flying insects.

Mars rover's laser can now target rocks all by itself

Thu, 07/21/2016 - 19:14
New software is enabling ChemCam, the laser spectrometer on NASA's Curiosity Mars rover, to select rock targets autonomously -- the first time autonomous target selection is available for an instrument of this kind on any robotic planetary mission.

An accelerated pipeline to open materials research

Thu, 07/21/2016 - 19:14
The Bellerophon Environment for Analysis of Materials (BEAM) is an ORNL platform that combines scientific instruments with web and data services and HPC resources through a user-friendly interface. Designed to streamline data analysis and workflow processes from experiments originating at DOE Office of Science User Facilities at ORNL, such as the Center for Nanophase Materials Sciences and Spallation Neutron Source, BEAM gives materials scientists a direct pipeline to scalable computing, software support, and high-performance cloud storage services.

Scientists program cells to remember and respond to series of stimuli

Thu, 07/21/2016 - 19:12
Engineers have programmed cells to remember and respond to events. This approach to circuit design enables scientists to create complex cellular state machines and track cell histories.

Imaging software predicts how you look with different hair styles, colors, appearances

Thu, 07/21/2016 - 18:41
How can we predict if a new haircut will look good without physically trying it? Or explore what missing children might look like if their appearance is changed? A new personalized image search engine developed by a computer vision researcher lets a person imagine how they would look with different hairstyles or appearances.

Artificial muscle for soft robotics: Low voltage, high hopes

Thu, 07/21/2016 - 18:39
A dielectric elastomer with a broad range of motion that requires relatively low voltage and no rigid components has now been created by scientists. This type of actuator could be used in everything from wearable devices to soft grippers, laparoscopic surgical tools, entirely soft robots or artificial muscles in more complex robotics.

GPS jamming: Keeping ships on the 'strait' and narrow

Thu, 07/21/2016 - 18:38
Researchers are investigating how to prevent shipping Global Positioning Signals (GPS) being jammed in potential cyberattacks that may cause vessels to go off course and collide or run aground.
