X-Ray Triggered Nanoparticle Photosensitizer: Photodynamic Therapy

April 19, 2014April 18, 2014 Pooja Kashyap

While working upon new security-related radiation detection, researchers at the University of Texas, Arlington discovered an advance in photodynamic cancer therapy. Wei Chen, professor of physics at the UT Arlington, noticed an odd luminescence emitted by copper-cysteamine (Cu-Cy) nanoparticles when while working on an experiment where he was exposing the nanoparticles to X-rays. Upon further investigation, he found out that the luminescence was the byproduct of lost energy that the particles were diffusing. The same byproduct is also utilized in photodynamic cancer therapy to destroy cancer cells.

Bright Points in Solar Atmosphere: Gateway to Sun’s Roiling Interior

April 18, 2014 Pooja Kashyap

NASA’s Solar Dynamics Observatory (SDO) has been able to collect data regarding the depth of the shining star, bright spots in the solar atmosphere and the strings of magnetic signatures observed on the surface of Earth. With this data, space scientists will get a peek into the insights related to the real-time mapping of the sun’s roiling interior. These understandings will help them on converging the decade long investigations of its 22-year sunspot cycle and emission of solar flares. As per Scott McIntosh, one of the lead researchers, this data…

Optimizing the Storage of Solar Energy in Chemical Bonds: Solar Thermal Fuel

April 16, 2014April 16, 2014 Pooja Kashyap

Researchers from MIT and Harvard University have come up with an innovative approach of tapping sun’s heat in form of chemical energy and releasing as per the requirement. The technique is not aimed for replacing the existing solar energy storage problem rather it is an effort of taking the solar power into the new areas which otherwise was not explored before. For instance, the output via this approach is heat, which could be directed towards cooking or industrial avenues where heat is required for powering processes. Molecules Act as Rechargeable…

Algorithm Aiding Machines for Determining Navigation: Scene Understanding

April 15, 2014April 15, 2014 Pooja Kashyap

Re-orientation of scenes and multi-target tracking are the fundamental problems for majority of vision applications. Occlusions and slight change in scene alignment make tracking by detection approaches a lot more challenging. Thinking on the same lines, MIT researchers have come up with a new algorithm that would assist the vision applications in combating the re-orientation problems. The algorithm is chiefly written for bots and machines that are employed for navigational purposes. Manhattan Frames The mechanism is based on recognizing the main orientations in the given scene. These alignments act as…

Silicon Photonics Chip Mimics Human Brain

April 14, 2014 Pooja Kashyap

Researchers from Ghent University came up with a breakthrough approach by demonstrating processing of information on a chip, mechanism of which was based on the functioning of human brain. Artificial neural networks or the bio inspired technique has been used in the past to bring about complex tasks which otherwise would have been tricky to solve by rule-based programming like computer vision and speech recognition. The researchers applied 16 nodes of neural network directly in hardware with the help of silicon photonics chip. Unlike the traditional computer chips that require…

Living Computers inside Alive Cockroaches to Deliver Drugs: DNA Installed Nano-Robots

April 13, 2014April 13, 2014 Pooja Kashyap

In an attempt to study complex programs and to identify and cure certain diseases, researchers at the Wyss Institute at Harvard University and Bar Ilan University in Israel, have come out with a breakthrough that involves DNA-based nanobots. Researchers were able to embed these nanobots into a living cockroach. These origami robots bear fluorescent markers that allow the scientists to predict about their location within the insect. By interacting with each other, these nanobots were seen performing simple logical operations as well claimed the researchers.

Face-on Alignment More Efficient in Generating Power: Organic Solar Cell Technology

April 11, 2014 Pooja Kashyap

In an attempt to study the viability of organic solar cell technology, researchers from North Carolina State University and UNC-Chapel Hill have discovered that efficiency of energy transference within three-dimensional organic solar cells increases relatively when there is face-to-face alignment between the donor molecules and the acceptor molecules. Exciton or the concentration of energy formed by excited particle upon absorbing by the material is the phenomenon upon which efficiency of organic solar cells is dependent. Within a solar cell, easier the exciton between the donor and acceptor molecules, higher will…

Squarepusher and Z-Machines: Music Performing System

April 11, 2014April 11, 2014 Pooja Kashyap

Squarepusher, UK based recording artist famous for the live instrumental playing and digital signal processing has again hit the music world but this time, in a collaborative effort with the Z-Machines, Japan’s party robot band. The evolved band has come up with a 78-fingered guitarist stringing out with 12 picks and a dreadlocked robot drummer. The effort is to explode the stereotypical myth, says Squarepusher where people think human touch or emotion is necessary to churn out the melody, which goes into the music. He wanted to prove that machines…

New Laser Technology Allows for Controlling Lightning Strikes

April 2, 2014 Pooja Kashyap

Researchers at the University of Arizona and the University of Central Florida have created a technology that has an ability of beaming high-intensity lasers all the way through the layers of atmosphere hence crossing the limitations that it had before. The research is still in its testing phase but the optical scientists envision that it might steer lightning strikes away from human inhabited areas and buildings. Extending the laser beam Lasers undergo diffraction because of which it fades away after beaming some feet only. This phenomenon does not allow it…
