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.

What is common between albumin, gelatin and casein? They are all proteins! And not just that, they are proteins used for the synthesis of nanoparticles. Proteins are large biomolecules that are composed of long chains of amino acids. The chemical groups that the amino acid are composed of lead to the protein having polar (water soluble) and nonpolar (water insoluble) regions. Hence when introduced into water, proteins tend to bury their nonpolar region by folding into different 3D shapes.
Captivity and confinement has had devastating effects on humans and the same can be true in the case of wild animals, especially the big cats. In this new study, scientists observe the hormones produced by captive big cats, like the Bengal Tiger or Leopard, to measure the amount of stress they endure during captivity. The study also throws light on stereotypy - a coping mechanism developed by captive animals, and its relation to the amount of stress they experience.
The Center for Disease Control and Prevention estimates that one third of the world’s population is infected with Tuberculosis (TB) . India accounts for the quarter of the world’s burden of TB and has the highest number of multidrug resistant TB cases worldwide. While multidrug resistant TB poses a major challenge for healthcare providers worldwide, many steps have been taken to treat this form of disease and control its spread.
Red blood cells (RBC) are the primary carriers of oxygen in all the vertebrates They pick up oxygen from the lungs, flow through the circulatory system and deliver the oxygen to the different cells and tissues. White blood cells (WBC), on the other hand, are the bodies primary defense system. Produced in the bone marrow, WBC helps the body fight invaders, like virus and bacteria.
The warming climate has made the world panic. Although some countries are still skeptical, most scientists agree about the inevitable rise in the temperature of the planet by the year 2030. Several countries have already started a shift towards renewable sources, like solar and with the Paris agreement, the world joined this movement.
India today faces several challenges, an air pollution is one of the important one’s to overcome. Four Indian cities often features on world’s top 10 most polluted cities. And lack of data has prevented us from understanding effects of the pollution and take measures to tackle them. A new study now shows that one’s daily routine can be a good indicator for the level of pollution one might face. It has already shown us that people travelling in cars and CNG buses face a lot less pollution and could help us find a lot more solutions to our pollution woes.
Plant based derivatives that cure cancer are a plenty with scientists discover more of them with time. One on the list from a long time is Resveratrol, a compound found in grapes, peanuts and berries. But how does this compound fight with cancerous cells? A new study has now thrown some light on the exact mechanism of how derivatives from resveratrol acts on cancerous cells and kills them, in the process, letting the other healthier cells remain unharmed. This discover, the researchers claim, can help scientists in developing more efficient drugs that can fight cancer, a deadly disease.
Cancer remains one of the most terrifying disease to face, despite decades of research and billions of dollars spent. They are a group of diseases that begins with abnormal cell growth, which then spreads to other parts of the body, causing huge damage to the tissues and cells. Once a patient has been diagnosed with cancer, doctors can only try and remove the spreading tumors or control their growth. Even if the tumors have been successfully removed, they are likely to return, making a visit to the doctors a regular affair.
