Vitamin D Deficiency Associated with Melanoma: Skin and Bone Health

January 17, 2023January 17, 2023 Pooja Kashyap

Vitamin D plays an important role in regulating normal function of human body. It helps the body to absorb and retain calcium and phosphorus, which are critical for building bone. In addition, it also helps in boosting energy levels. Epidemiological studies too, have shown that Vit-D deficiency is closely associated with common chronic diseases such as bone metabolic disorders, tumors, cardiovascular diseases, and diabetes. In addition, similar corelation between vitamin D and skin cancers have also been investigated.

Human Brain Organoids Implanted in Mice: Human-mouse Synapses

January 10, 2023January 11, 2023 Pooja Kashyap

An international team of neuroscientists has demonstrated that human brain organoids when implanted in the cerebral cortex region of a mice can respond to external sensory stimuli. Brain organoid, here, refers to a three-dimensional tissue that is made from skin cells.

Book Review: The Matter of Everything by Dr. Suzie Sheehy

January 6, 2023February 21, 2023 Pooja Kashyap

The Matter of Everything is penned by an accelerator physicist Dr. Suzie Sheehy. The book introduces us to the time when physicists were about to unravel the mysteries of matter via exploration of subatomic particles. And it all started with a serendipitous discovery by the German physicist Wilhelm Röntgen, who in 1895, was working with a cathode ray tube in his laboratory. He noticed that the phosphor-coated screen was giving off a green coloured light when exposed to a cathode ray tube.

Book Review: The Gods Themselves by Isaac Asimov

December 30, 2022December 30, 2022 Pooja Kashyap

Energy transfer between parallel universes, the idea is enough for any science fiction fan to pick up and read this awesome piece of work. The Gods Themselves is one of the earliest and fantastic read on multiple universes, nuclear forces, and Big Bang. The fundamental idea of why Big Bang occurs and the repercussions of disturbing the laws of physics that govern universe(s), are explained in the most simplified and narrative style by Isaac Asimov.

Wearable Electrotactile Feedback System: Skin VR

December 29, 2022December 29, 2022 Pooja Kashyap

Haptic systems are mainly designed to control virtual objects. Their efficacy is good, but when it comes to controllers, joysticks, and steering wheels, things look slightly bulky. And tangled wires is another task to deal with. Researchers at City University of Hong Kong have come up with a portable solution to enhance the tactile VR experience.

Interview: Wa’d AbuZurayk, a Neurotherapist and Paediatric Occupational Therapist, Jordan

December 20, 2022December 20, 2022 Pooja Kashyap

Wa’d AbuZurayk is the first qualified neurotherapist and paediatric occupational therapist in Jordan. She has attained her licensed device from Germany. The device is both FDA and internationally approved. She is also the founder of Ujeed, Child Development Consultations in Amman, Jordan. These days most of her time is occupied with families to create their own unique narrative through neurotherapy, occupational therapy and a pinch of magic.

Microbial Miners to Colonize the Moon and Mars: Biomimetic Mining

December 13, 2022December 13, 2022 Pooja Kashyap

Evolutionary biological processes take time but what if we introduce microbial catalysis to the system? The phenomenon of how cyanobacteria obtain nutrients for its survival from rocks in Atacama Desert inspired an international team of collaborators from University of California and Johns Hopkins University to consider the microbes as tools that may help humans to develop colonies on the moon and Mars.

Active Mantle Plume on Mars: Martian Geodynamic Evolution

December 7, 2022December 12, 2022 Pooja Kashyap

Cumulative evidence, so far has suggested that Mars once had oceans but then lost its atmosphere and eventually died out. Unlike Earth, where shifting tectonic plates make way for dynamic interior, Mars never surfaced such processes. Hence, the astronomers concluded that nothing much happened on the red planet, at least, in the last 3 to 4 billion years. Recent observations by the scientists at the University of Arizona, however has challenged the current views of Martian geodynamic evolution. As per them, the red planet, that seems to be dead, has an…

Butterfly Robots with Bistable Wings: Biomimicry

November 24, 2022January 11, 2023 Pooja Kashyap

In an effort to create faster and more energy-efficient soft robots, researchers at North Carolina State University have created a prototype of swimming soft robots based on manta rays. The team got inspired from the biomechanics of the marine animal. Rate of swimming for most of the (swimming) soft robot is one body length per second, manta rays, however, glide at much faster rate. Their swimming efficiency triggered the scientists to look into the potentiality of creating a similar robot, biomechanically.

Retinal Movements of Spider suggest REM Sleep: Arachnid is Dreaming

August 11, 2022August 11, 2022 Pooja Kashyap

After researchers have figured out that spiders use their silk to hear, scientists have discovered that arachnids have patterns of sleep cycles. In one such observation, they not only twitched their legs toward the sternum but and flickered parts of their eyes. The phenomenon is similar to REM sleep-like state.

A Super-Earth orbiting Dwarf Ross 508: Exoplanet Exploration

August 9, 2022August 9, 2022 Pooja Kashyap

Astronomers work ceaselessly to find out clues that might point out to the existence of extra-terrestrial life some where in outer space. The mere idea that we might not be alone is enough motivation to work constantly in this hunt. Lately, there has been an increase in the number of research probing into exoplanets. In one such research, astronomers have discovered a super-Earth like planet near the habitable zone of a red dwarf star. It is about 37 light-years from the Earth. This also happens to be the first such…

Crab Inspired all weather Vision System: Biomimicry

August 4, 2022August 4, 2022 Pooja Kashyap

To improve the imaging component in robotics, researchers have been trying to create various types of highly performing cameras, sensors and artificial vision systems. Most of the vision systems are bio-inspired that is, they have been emulated from the systems and elements of nature including humans, animals, insects and fish. These systems, however, have their own restrictions because they operate in limited environment respectively. For instance, majority of (bio-inspired) existing sensors and cameras works either one of the following scenarios: on the ground like biomimetic eye with a hemispherical…
