Scientists discover mesentery, a new human organ in digestive system

Scientists from Ireland have claimed discovery of a new human organ named the mesentery that exists in the digestive system. It will be human body’s 79th organ. Mesentery connects the intestine to the abdomen.  The organ was previously thought to consist of fragmented and disparate structures. Key Facts Mesentery is a fold of the peritoneum Read More…

Scientists develops first Biological Pacemaker using Human Stem Cells 

Scientists from Canada have developed the first functional pacemaker cells using human pluripotent stem cells.  The cells can regulate heart beats with electrical impulses. It paves the way for alternate biological pacemaker therapy. Key Facts  Pluripotent stem cells have the potential to differentiate into more than 200 different cell types that make up every tissue Read More…

Scientists use ‘pregnancy fluid’ to strengthen weak bones

UK-based researchers have found that stem cells harvested from pregnant woman’s amniotic fluid can be used to strengthen weak bones. Amniotic fluid is the protective fluid that surrounds baby in the uterus and helps it to develop inside the mother’s womb. It also contains stem cells that are the building blocks of other tissues. Key Read More…

Researchers discover mutated Atlantic killifish resistant to toxic waste 8,000 times

Researchers discovered Atlantic killifish, a fish species which has evolved to be 8,000 times more resilient to toxic waste compared with normal fish. The fish species lives in the heavily polluted East Coast estuaries of US such as the Elizabeth River in Virginia and the Newark Bay in New Jersey. Key Facts The evolution has Read More…

Researchers found novel route to discover new drug targets

Researchers from the International Centre for Genetic Engineering and Biotechnology (ICGEB), Delhi have found a novel route to discover new drug targets and potential drugs. These new drug targets route and potential drugs are mainly for parasites such as Loa loa nematode (roundworm) and Schistosoma mansoni platyhelminths (flatworm) that cause several diseases. Why these parasites Read More…
