Graphene Sheet morphs into Droplets: A Serendipitous Discovery

Pooja Kashyap

Graphene does not stop surprising researchers with its limitations when it comes to application in fields like electronics, energy storage and energy generation. The list does not end here, now the wonder material looks promising in domain of medical sciences as well. During routine tests, Monash University’s researchers discovered that sheets of graphene oxide morph into liquid crystal droplets on its own accord. With its new avatar, the graphene droplets have find a promising place in delivery of drugs and disease detection, claimed the researchers.

Reconstructing Audio from Infinitesimal Vibrations: Algorithm recovers Sounds from Objects

Pooja Kashyap

In an extraordinary way of recovering speech from vibrations of things like potted plant and potato chips bag, researchers at MIT, Microsoft and Adobe have created an algo that can decipher audio signal by analyzing the object’s infinitesimal vibrations. Upon performing experiment on detecting vibrations of a potato-chip bag, the researchers were able to reach a good precision with respect to speech. The bag was being photographed by a high quality camera with a distance of 15 feet installed in a soundproof glass-room.

Hellacious Lava Fountains on Jupiter’s Moon Io: Curtains of Fire

Pooja Kashyap

Within a two-week period Io, Jupiter’s moon, experienced two massive outbursts in August 2013. Astronomers speculated that these volcanic eruptions could be regular phenomenon that can spew materials in huge quantities above the surface. If we talk about ratio, it could be somewhere from one huge outburst per one or two years but Io suggested more than this. Io is the innermost moon out of the planet’s four large Galilean moons. It is more than 3,600 km across. It is the only space body that is known so far, by…

Japan to create Space Force to Monitor Debris: The Fourth Battlefield

Pooja Kashyap

Space debris are affecting our vital services and if it continuous to do so then time is not far when we would no longer be able to communicate, the financial markets would be paralyzed, no TV, no internet, no phone calls, no satellites, life would come to a halt, literally! Satellite collisions would initiate the catastrophic snow balling effect amplifying the cascade of destruction. The movie Gravity did call for some serious thinking about the impacts that debris can cause. Although the movie had some serious flaws but that is…

Glucose Sensor in Brain Discovered: Controlling Blood-Sugar Level

Pooja Kashyap

Experts at Yale School of Medicine have identified a control switch of glucose within brain that has a direct linkage with both type 1 and type 2 diabetes. Ventromedial nucleus (VMN, or ventromedial hypothalamus, VMH) is a nucleus of the hypothalamus that contains an enzyme called the prolyl endopeptidase. This enzyme initiates a chain of steps that assist in controlling the levels of glucose in blood stream. Researchers envision that this finding would help them in leading towards new treatments for diabetes.

New Spray-on Solar Cells: Thin-film Photovoltaic Technology

Pooja Kashyap

In an interesting way, a group of researchers at the University of Sheffield was able to develop perovskite solar cells with the help of spray-painting process. Although the process is not new but using perovskite as a spraying material is being employed for the first time. Sheffield’s experts from the department of Physics and Biological Engineering have already used the spray-painting process to fabricate solar cells but the material used was organic semiconductors. In 2012, the researchers were able to successfully demonstrate the efficiency of photovoltaics based on organometal halide…

Earlier Asteroid Impacts led to the formation of Earth’s Crust: Geological Evolution

Pooja Kashyap

Last year we talked about how meteor impact led to pastoral revolution and now recent research on Earth’s surface revealed that the planet was in a constant reprocessing process due to the huge asteroid impacts. The new approach utilizing the terrestrial bombardment model based on lunar and terrestrial data disclosed that asteroid collisions where the game changer which caused evolution of the topmost layers of Earth during its initial stages, which happened around 4.5b years ago. Yvonne Pendleton, NASA’s Solar System Exploration Research Virtual Institute (SSERVI) Director added that repeated…

Color changing Ice Cream: Fruit-flavoured treat invented by a Physicist

Pooja Kashyap

In an interested way in doing something unconventional, a Spanish physicist pioneered in preparing magical ice cream that changes color as it is tasted in a cone. Wanting to do something different from the usual research work, the engineer, professor and physicist Manuel Linares thought of doing something in the line of cookery. His love for ice cream and fascination towards the phenomenon, which causes its change in color under fluorescent lights, compelled him to create an ice cream that varies in color as per the temperature and acids found…
