Scientists from the Indian Institute of Science Bangalore devise a computational model to study how cooperation evolves in natural systems - from cells to large mammals. The study finds mobility, which was largely ignored before, plays a key role in the evolution of cooperation. Understanding mobility of cells in a medium could help us understand better the spread of cancer.

Cancer is a difficult disease, both for patients and doctors. One of the many side effects of cancer therapies is secondary infections that are caused by a weakened immune system. Current strategies for treating bacterial infections in cancer patients have many drawbacks. Addressing these issues scientists from the Indian Institute of Technology, Delhi show that administering antimicrobial medicines with gold nanoparticles increases their efficacy by upto 40%.

Cancer, as a disease, is a puzzle on its own and scientists across the world are looking for hints from all sides to crack it. Now, what if previous research on cancer itself acts as a hint and guides new developments? That is exactly what scientists have done using bioinformatics. By scouting previous research on circulating tumour cells, scientists have identified the molecules responsible for metastasis in cancer. This discovery, they believe, can help not only in understanding the spread of cancer, but also in identifying new drug targets against the killer disease.

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. 

The incidence of prostrate cancer, affecting the prostate gland in men, is one of the increasingly growing types of cancers and the cause of death across the world, particularly in developing countries. While traditional anti-cancer treatments like chemotherapy and radiation therapy promise hope, they often come with undesirable side effects. In a new research, scientists have shown the possibility of natural extracts from two plants found in tropical regions of the country to be effective against prostate cancer. This research definitely promises to bring in new hopes in those battered with cancer, hope the scientists.

The body’s immune system is one of the robust defense mechanisms. Now, scientists are exploring to use our immune system to fight some of the deadliest diseases including cancer by understanding how immunotherapy works and how drugs that are based on immunotherapy help our body fight cancers. In a recent study, researchers are working on understanding how Yervoy, a common immunotherapy drug against cancer, works in fighting against the disease. They are also looking at manufacturing similar cost-effective drugs that promise to bring down the cost of cancer drugs.

Tobacco is one of the five most addictive substances in the world. No wonder, there are so many people around the globe who use tobacco in various forms. Nicotine, the chemical in tobacco leaves soon takes its toll by causing various health complications, sometimes fatal too. Apart from affecting health, unabated tobacco use can cripple a country’s economy and cause a dent to its productivity. Today, on World No Tobacco Day, read more to know how tobacco harms an individual and a society and what steps countries around the world have taken to curb this menace.
