May 15, 2014June 18, 2014 Pooja Kashyap

Even though we have made tremendous progress in science, yet there remains a mystery when it comes to give reasons to some everyday activities. These mundane stuffs generate the same kind of awestruck curiosity to scientists as it does to a toddler. Some of these bewildering questions are: 1) Slipperiness of Ice The unusual & unique properties of water have given numerous explanations about ice being slippery. Experts have dispensed most of the theories propagated so far and there could be more variations in the future discoveries envision majority of…

Stimulating Neurons can modify Human Learning: Curbing the Addictive Behaviors

May 14, 2014May 31, 2014 Pooja Kashyap

Neuroscientists at the University of Pennsylvania have put forth a research as per which excitation of a set of dopamine-sodden neurons within the brain has substantial chances of altering the learning process. These neurons are present in substantia nigra, the grey matter in the midbrain. Stimulating this patch of the brain has resulted in altered learning by swaying people to reiterate physical actions leading to positive reinforcement producing immediate reward. For the experiment, eleven individuals who were going through deep brain stimulation (DBS) treatment for Parkinson’s disease were taken into…

GU Psc b: Another Exoplanet Discovered Through Direct Imaging

May 14, 2014 Pooja Kashyap

Space scientists have discovered a new planet by collective observations from the Gemini Observatories, the Observatoire Mont-Mégantic (OMM), the Canada-France-Hawaii Telescope (CFHT) and the W.M. Keck Observatory. The gas giant is situated around GU Psc, in the constellation Pisces and is believed to be 3 times less massive than the Sun. The distance between the planet GU Psc b and its star GU Psc is approximately 2,000 times Earth-Sun distance. With this distance, it would take the planet nearly 80,000 Earth years to complete just one orbit around its star.…

21st century heralds the supercars that not only give preference to speed but also give equal importance to safety, reliability and spaciousness where minimum fuel consumption and less carbon emissions comes in as default features of course. The new Lamborghini Huracán LP 610-4 rolls in at the same time and earns full marks in all the set parameters. Huracán made its presence felt in the 2014 Geneva Auto Show, where it replaced Gallardo, the most sought after sports car from the same company. The exotic is expected to release somewhere…

Biomimicry: Tabbot Mimics Cartwheel Movement of Desert Spider

May 9, 2014 Pooja Kashyap

After the termites inspired crew of tiny autonomous bots, insect-inspired Micro-Robots and Gimball, biomimicry has a new entrant called the Tabbot. It is a tiny bot inspired from Morocco based spiders famous for doing cartwheels effortlessly. Interestingly, these spiders are capable of doing cartwheels up and down the sand dunes. Ingo Rechenberg, a professor at the Technical University of Berlin has been credited for this discovery. In order to preserve and utilize the resourcefulness of this unique mode of locomotion, the researcher has already fabricated a small bot that works…

Right Enzymes Replicated the Semi-Synthetic DNA: Expanded-DNA Biology

May 9, 2014 Pooja Kashyap

Scientists always dig deeper into the functioning of nature in order for their better understandings. At times, these trials and errors have given rise to serendipity or accidental discoveries in science, amongst others, recent being how sliding saltwater over graphene generated electricity. While at other times, these experiments go beyond the natural order of workings even at the miniscule level.

Illustris is New Time Machine: Simulation of the Realistic Virtual Universe

May 8, 2014May 8, 2014 Pooja Kashyap

We know how our universe look today and we have pretty good idea as to how it looked before the things started taking shape somewhere around the Big Bang. But we have no idea how the galaxies evolve and what was before the Big Bang. In order to study this, researchers at the MIT have built a computer simulation, they have named it the Illustris. This simulation is so complex that calculating on single desktop might take 2k years alone and its volume comprises around 215m light years. Although there…

Magnetic Fields in Electric and Hybrid Cars Involve No Threat: Cars under Safety Margin

May 7, 2014May 16, 2014 Pooja Kashyap

Majority welcomed the vehicular era when electric and hybrid automobiles took to the center stage. While there were still others who were doubtful regarding the dangers that might affect the passengers including drivers imposed by the possibly generated electromagnetic fields. However, the increasing number of electric car ownership has thwarted this idea. Seven various electric cars, including hydrogen, gasoline and diesel powered cars, were put under survey by SINTEF, Norway and they discovered that exposure of the electromagnetic radiation was less than 20%. A limit, which was suggested by ICNIRP,…

10 Ways to Conserve Smartphone Battery Life: The Power Management

May 7, 2014 Pooja Kashyap

Technology behind smartphone is evolving at a very fast pace, unlike the past era, people are not reluctant to adopt the new expertise with respect to their devices. However, when it comes to battery life, the same people then take a back seat before delving deeper into the ocean of technology. Smartphones have witnessed a major leap in terms of huge screen, fast CPUs and other eye catching system features but batteries still haven’t crosses the initial threshold. Till the time, technology behind new super batteries make its heyday, we…

Human Brain Simulated on Circuit Board: Mimicking Neurons and Synapses

April 29, 2014May 31, 2014 Pooja Kashyap

Inspired by human brain, bioengineers at Stanford University have fabricated microchips that are relatively faster and energy-efficient where power consumption of PC is about 40k times more. Researchers envision that this would lead a novel way of understanding human brain as well as might take robotics especially prosthetics to the next level. Matching the Brain For an efficient mimicking of neurons and synapses, the team designed 16 Neurocore chips. Jointly these 16 chips were able to simulate about 1m neurons and billions of synaptic connections.

Propagating Light Revealed New Fundamental Physical Features: Evanescent Electromagnetism

April 28, 2014 Pooja Kashyap

Dynamical properties of light have been consistent and very well accepted ‘fact’ amongst the academia of physics since more than a century. The same conviction has also helped in the understanding of electromagnetic radiation, which suggests that a quantum of light carries momentum in the direction of propagation and secondly a spinning or gyrating effect around the propagation axis. These two characteristics have become the basic tenets of daily occurrences and experimental interactions between light and matter. However, a new form of light called the evanescent waves has emerged having…

Newly Discovered Neighbor of the Sun: Chilly as the Earth’s North Pole

April 27, 2014May 3, 2014 Pooja Kashyap

Kevin Luhman, an astronomer at Penn State University has discovered a star, “brown dwarf” that is around 7.2 light-years away. Currently it appears to be as cold as Earth’s North Pole and positioned at fourth rank with respect to the Sun. The space scientist claims that insights from the new system might helpful in knowing the atmospheres associated with cold temperatures on similar other systems. Like stars, the brown dwarfs initiate the same life cycle but during the collapse, they lack the mass that is required to burn the nuclear…

Fabrication of Bi-Layer Molecular Electronic Devices: Nanoscale Circuitry

April 22, 2014 Pooja Kashyap

Until now, it was difficult to charge particles at molecular scale and hence developing circuits at microscopic level has always presented a huge challenge. However, Alexander Shestopalov from University of Rochester has crossed the huddle making a step closer to the fabrication of microscopically small circuit. He powered an organic light-emitting diode (OLED) with a nanoscale circuitry in where he coupled the positive and negative electrodes with one-molecule thin sheet of organic material. Experimental trials and errors have proved that it’s impossible to control current passing through such a single…
