Eyes have been described as one of the most beautiful organs of our body that is our window to the world, quite literally. But not everyone is fortunate to look through that window crisp and clear. Millions today suffer from blindness in the eyes due to many medical conditions. The good news is that some type of blindness like corneal blindness is completely curable, provided there is a generous soul that decides to donate his/her eyes at the time of death. Eye donation is slowly gaining awareness and many today are pledged donors. But how does one become a donor? How is the cornea taken from the donor and what is the status of eye donation in India? Find out more on the account of National Eye Donation fortnight.

Unicellular microalgae cells living in freshwater sources are constantly exposed to stimuli and stresses of all kinds, be it changes in temperature, salinity, drought or pathogenic attacks. With climate change and rapid diminishing glaciers, these variations of the environment will continue to get worse. Sensing, reacting and mitigating the harmful impacts of such drastic environmental alterations becomes a matter of survival for these algal cells.
Planarians have fascinated scientists for decades. Their prowess of regeneration allows the planarians to grow entire individuals from a tiny fragment of the body, or for individuals to generate multiple organ systems upon making an incision. Various studies have explored the genetic mechanism behind this regeneration in the organism. In a recent study scientists from Institute for Stem Cell Biology and Regenerative Medicine have uncovered the function of microRNA's a particular kind of genetic material in the regeneration of brain and eyes in planarians.
India is a country whose population largely depends on agriculture, with 50% of its population being employed in agriculture, and revenue from agriculture and other allied fields contributing 13.7% of our country’s GDP. Most farmers in India face various challenges on a day-to-day basis and disposing off the agricultural residue that remain after a crop is successfully harvested, is one such major issue faced by millions of farmers.
Happy Teachers Day! As we celebrate the 55th Teacher’s Day today in rememberance of Dr. Sarvepalli Radhakrishnan's birthday, let us take this opportunity to thank every teacher who played a great role in making us who we are. And for those teachers who are teaching science, here is a wish to make it fun and enjoyable rather than rote and mundane!
Cancer, described as the ‘emperor of all maladies’ by Siddharth Mukherjee’s book by the same name, is a disease which needs no introduction. Currently regarded as a collection of diseases, cancer is most accurately characterized by an unregulated growth of cells within the body - be it within organs like the pancreas, lungs and brain, or fluid connective tissues like the blood. Given that cancer itself is so diverse and multifaceted, there are many therapies used to combat it, like chemotherapy, radiation therapy, surgery and immunotherapy, to name a few.
Organic farming, a method of farming that uses no artificial pesticides or fertilisers, is a re-emerging practice in agriculture and is seen as a new hope in times where our lands are ravaged by chemical fertilizers. Following this method has multiple benefits among which maintaining soil health is one. But how much of ‘good’ does it do to soil? A new research has now studies the various long and short term effects of organic farming on soil health and has found that in comparison with conventional farming methods, organic farming results in better soil health as indicated by its physical, chemical and biological properties
Earthen pots or matkas have been used to store and cool water since time immemorial. But how do they keep water cool?
India’s premier institutes like the Indian Institute of Science (IISc) and the Indian Institutes of Technology (IIT) are the most sought after institutes in the country that attract the best of the talent from across the country. But how do these national institutes compare with those in Singapore, a major hub of education in Asia? A new study by researchers from the Vidya Academy of Science and Technology, Thrissur and A.P.J.
The intricate working of human cells has been a fascinating subject and every now and then we have a new research throwing light on how cells and their constituents help form what we know as ‘life’. Now, a new study has explored the organization and function of mitochondria, a cell organelle responsible for providing the cells with energy that they need, in the context of early embryonic development. The researchers have shown how mitochondria move about in the cells using the cytoskeleton and help in formation of different cells from the blastoderm.
