Scientists identify evolutionary pathway of pitcher plants

According to new study was published in the journal Nature Ecology and Evolution, scientists have identified the evolutionary pathway that led some plants to turn carnivorous. The new finding explains why pitcher plants (carnivorous plants) from different parts of the world appear strikingly similar despite having evolved independently. Pitcher Plants Pitcher plants or carnivorous plants Read More…

World’s smallest pacemaker unveiled in US

Scientists for the first time have successfully implanted world’s smallest pacemaker dubbed as Micra Transcatheter Pacing System (TPS) in a patient in United States. The pacemaker about size of large vitamin capsule is for patients with bradycardia, a condition characterised by a slow heart rate, usually fewer than 60 beats per minute. Key Facts TPS Read More…

Researchers Discover Oldest Human Ancestor

Researchers have discovered microscopic sea animal Saccorhytus, the earliest known ancestor of humans along with a vast range of other species. The exquisitely well preserved fossilised traces of this 540-million-year-old creature were discovered. This balloon-like sea is the earliest known step on the evolutionary path that led to fish and eventually to humans.  About Saccorhytus Read More…

Scientists creates world’s first stable semi-synthetic organism

Researchers from The Scripps Research Institute (TSRI), US have created world’s first stable semi-synthetic organism, a single-celled bacterium with an expanded genetic code The semi-synthetic organism is the modified E.coli bacteria created by introducing DNA molecules that are not found in nature in a common bacterium. How the new bacterium was created? Life’s natural genetic Read More…

US Researchers discover the function of human appendix

Researchers from Midwestern University have identified the function of the human appendix, often viewed as a vestigial organ with little-known use. They discovered that the human appendix has evolved at least 30 times and even possibly up to a maximum of 41 times throughout the mammalian evolution. Key Facts According researchers, once the appendix appears Read More…
