Purring in cats is quite common. While you may have seen a domesticated cat at your house or  in the neighbourhood purr, there is documented evidence of even larger cats such as tigers, lions, panthers and cheetahs which have been found purring in the wild. While cat owners often take purring as a good sign and end up lathering the feline with loads of attention and ‘awwwwwws’, the fact remains that no one really knows why cats purr. So, although, the common cat got domesticated into human settlements somewhere around 10,000 years ago, there is very little that we actually know about why they exhibit such behaviour. Modern scientific methods continue to be used to determine, what might seem to a trivial question. But all studies so far have only ended up adding more more speculated reasons as to why cats purr. Before we tell you to possible reasons for purring of cats, let us look at the question HOW do cats purr? Initially researchers had theorized that cats have a separat

Cure Cancer with TRAIL

Cancerous Cell Cancer cells are notorious for their ability to detach themselves from tumours, flow through the blood stream and find themselves new sites in the body to adhere to and grow in size and number. Called metastasis, this process allows cancerous cells to not only survive in the body but also regroup at some other site, where you are least suspecting them to be and show up their ugly side as tumours. Site specific radiation therapy or even chemotherapy, for that matter, lacks the specificity to attack cancerous tumour alone, let alone freely floating cells and therefore, in spite of all advances in medicine and all the treatments that are offered to patients, there has never been a 'cure' for cancer. This, however, might soon change.  In the mid 1990s, researchers Steven Wiley and his team at the Immunex Research and Development Corporation, Washington identified a new protein called TRAIL ( T NF- r elated a poptosis- i nducing L igand).
