Why Each Human Face is Unique


The human face is usually regarded as the main identity of a person as it is not common to come across another of the same person with the exact facial features with you. Even identical twins do not look exactly alike and here is the reason why each human face is unique.

A new study by researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has now shown that gene enhancers -- regulatory sequences of DNA that act to turn-on or amplify the expression of a specific gene -- are major players in craniofacial development which simply means your physical facial features such as the shape of your nose, eyes, ears, mouth, the distance between them etc.

Why Plants Live Longer Than Animals


In a research conducted by researchers at VIB and Ghent University, the researchers learn more about how plant stem cells function differently compared to animal stems cells which allows plants to live longer than animals.

What the researchers have found is as explained by Lieven De Veylder, one of the researchers, "Our data suggest that certain organizing stem cells in plant roots are less sensitive for DNA-damage. Those cells hold an original and intact DNA copy which can be used to replace damaged cells if necessary. Animals rely on a similar mechanism but most likely plants have employed this in a more optimized manner. This could explain why many plants can live for more than hundreds of years, while this is quite exceptional for animals."

A Monkey That Purrs



Over the course of four years—from 2010 to 2013— 441 new species were scientifically identified in the Amazon by WWF which includes a species of titi monkey that purrs like a cat.

The Caqueta titi monkey: This new species, Callicebus caquetensis, is one of about 20 species of titi monkey, which all live in the Amazon basin. The babies have an endearing trait, "When they feel very content they purr towards each other," explained scientist Thomas Defler.
