Technological advancement has opened-up exciting possibilities for research in space and celestial bodies beyond the Earth’s atmosphere. The use of robots in space exploration has greatly increased our understanding of other planets, especially Mars, and its possibility for supporting life. The exploration of Mars and its surface for extra-terrestrial life has always been a fascinating undertaking for astronomers. Additionally, the discovery of resources on Mars, such as water and minerals, could be an asset in future human missions.

Cancer treatments such as radiotherapy and chemotherapy have been shown to be less effective when exposed to a hypoxic environment. In fact, low oxygen levels in tumors can also escalate disease progression. Hyperbaric oxygen therapy and microbubble infusion are the two techniques through which oxygen levels in tumors can be increased to improve treatment outcomes.

In an international collaboration between astronomers, two planets orbiting a red-dwarf star have been identified. The planets, GJ 1002 b and c, are 16 light-years away and about the size of Earth. Both lie within the star’s habitable zone. Which means, the orbital distance is enough to allow liquid water to form on the surface provided it has the right kind of atmosphere.

My favourite thought experiment is the notion that as an individual approaches the speed of light, time slows down. Now let’s extrapolate it to Big Crunch scenario. What if an individual travel at the speed of light and reaches the end of universe? According to Russian Physicist Alexander Friedmann, end of the universe depends on its density. Therefore, universe cannot stay stable for ever, it could either expand or contract. Gravity, with the help of matter, could slow down the expansion, then stop, and ultimately reverse it. Everything collapses within…

Dr. David Eagleman is a neuroscientist at Stanford, NYT bestselling author, Writer/Host of THE BRAIN on PBS, and the list continues. After listening to his podcasts and TED talks, I decided to pick-up one book from his vault – The Brain: The Story of You. The book is an interesting read and at some points, quite an eye opener. Here, Dr. Eagleman reviews how the human brain develops and make sense of the data that it receives from sensory systems. We are built to perceive only thin slice of perception,…

Since the origin of life in 3.5 billion years ago, hundreds of millions of species might have lived on planet earth. Most of those are extinct by now. In his exceptional book, The Story of the Dinosaurs in 25 Discoveries: Amazing Fossils and the People Who Found Them, Donald R. Prothero has tried to surface those species that led to the landmarks in evolution. The idea was to signify evolutionary transition from one group to another. An interesting read for those who are looking for history of dinosaur science. Very…

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.

I, Robot by Isaac Asimov is a collection of short stories written between 1940 and 1950 and were composed together in 1950. To create an ethical system for the co-existence of humans and machines, Asimov, laid the foundation of the three laws of robotics, which were:

Dr. Yin received his Ph.D. in Engineering Mechanics from Columbia University. Prior to join NC State, he worked as a Postdoctoral Associate at MIT and an Assistant and Associate Professor at Temple University. He is the recipient of the NSF CAREER Award and Extreme Mechanics Letters (EML) Young Investigator Award.

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.

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.

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.

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.
