Black holes are the celestial objects with such immense gravity that nothing can escape from them -- not even light!

Researchers have always used bacteria, yeast, worms, fruitflies, fish and rodents in laboratories since experimentation on humans is often unfeasible and presents with an ethical conundrum. These model organisms are chosen depending on the nature and complexity of study and the cost and convenience of its maintenance. Zebrafish (Danio rerio) is today a favourite model organism for various biological research studies for well deserved reasons.
It is thought that free radicals are the cause of aging and can also cause or aggravate diseases like cancer and coronary heart disease. However, this is a highly debated topic and experiments have been conducted to show that this may not be true.
“Oh! Not again! Bees are buzzing all around the tube light. Now it's enough, I have to call the pest control guy and get rid of this hive ASAP!”. Before doing this, stop and imagine, how will the world be without honey bees?
Scientists at the Laser Interferometer Gravitational-waves Observatory (LIGO) recently announced the detection of gravitational waves. This comes exactly 100 years after Einstein had predicted their existence in 1916. This discovery has caused huge ripples of enthusiasm in the arena of astronomy. But what are gravitational waves?
Have you ever noticed that the price tag of daily consumables always comes with a 9 at its end - Like jeans with a price tag of Rs. 999 or mobiles with Rs. 4999? Instead of using 1000 or 5000, the merchants always prefer to choose these prices ending with a 9. Not only in shopping malls, but shops in your locality also use this same tactics to draw your attention.
What you do when you are sick? Obviously you go to a doctor. You tell him/her what your problem is, s/he examines you with a stethoscope to monitor your heartbeat at various regions of your body and then you get some medicines. Now, if your friend goes to the doctor with the same problem, s/he gets similar medicines.
In what could be called a testimony to Bengaluru being the IT capital of India, the Indian Institute of Science’s Computer Science and Automation (CSA) department was ranked 71st in the recently released The Times Higher Education World University Rankings 2016-2017, making it the top institute in India for Computer Science.
As Alfred Nobel quoted in his will, “For the greatest benefit to mankind”, the Nobel Assembly at Karolinska Institute, Sweden, has opened this year’s list by announcing the winner for Physiology or Medicine on Monday. Yoshinori Ohsumi from Japan has bagged the 2016 Nobel Prize in Physiology/Medicine for his “Discoveries of mechanism for Autophagy”.
When the Royal Swedish Academy of Sciences announced that the year’s Nobel Prize in Chemistry is about the world’s smallest machines”, the world had found the answer to another Nobel laureate, Richard Feynman’s question - How tiny can you make machinery? “The Royal Swedish Academy of Sciences has decided to award the 2016 Nobel Prize in Chemistry jointly to Jean-Pierre Sauvage, Sir James Fraser Stoddart and Bernard Lucas Feringa for the design and synthesis of molecular machines”, read a press note from the Academy. The machines developed by these laureates are controllable, nanometer sized objects, a thousand times thinner than a strand of hair, which can move around and perform a task when energy is added. The three winners will split the award equally, with each having played a different role in the development of molecular machines.
