A new study has found that fragile X syndrome, the most common genetic cause of mental retardation and autism, occurs because of a mechanism that shuts off the gene associated with the disease. Read on for more details. 

Researchers have found that plant-emitted aerosoles—the extremely low-volatile organic compounds—consist of relatively large molecules. They show how these vapors are formed almost immediately when plant emissions are released into the air. Read on for more details.

Using sophisticated plate tectonic and 3D numerical modeling, geoscientists have been able to show that break-up of the supercontinent Gondwana about 130 million years ago could have led to a completely different shape of the African and South American continent. Read on for more details. 

Researchers at the University of California have concluded that social networks among primates provide valuable lessons that could help predict catastrophes like the 2008 global financial crisis. Read on to find out more.

Over time, stem cells in damage-repairing muscle tissues struggle to regenerate. In a new study, scientists have identified a process by which the older muscle stem cell populations can be rejuvenated to function like younger cells. Read on to learn more.

It is widely believed that domestication influenced the abilities of dogs to form close relationships with humans. Although wolves and dogs are closely related, scientists suggest that wolves observe one another more closely than dogs do and are better at learning from one another.

In a new study, researchers have concluded that the majority of circumbinary planets must have formed much further away from the central binary stars and then migrated to their current location. Read on to find out more. 

Exposure to blue light during the day directly and immediately improves alertness and performance, says a new study. Researchers from Brigham and Women's Hospital (BWH) compared the effects of exposure to blue light with exposure to an equal amount of green light on alertness and performance in 16 study participants.

It has long been held that there are six universally recognized basic emotions that can be easily interpreted through facial expressions: happiness, sadness, fear, anger, surprise, and disgust. However, new research suggests that there are actually only four. Read on for more details. 

Scientists have discovered the first binary system ever known to consist of a black hole and a Be star. Read on to know more.
