Previous studies have shown that the extracts from seeds of the Moringa oleifera tree can be used for water purification. In a new study, researchers from Uppsala University show that the Moringa seeds can also be used for separation of different materials. Separation processes are very important in mining industries and the new knowledge could contribute to reduce the needs for expensive synthetic chemicals.

The Sahara Desert and the Amazon rainforest seem to inhabit separate worlds. The former is a vast expanse of sand and scrub stretching across the northern third of Africa, while the latter is a dense green mass of humid jungle covering northeast South America.

Infants born prematurely are more than twice as likely to have difficulty hearing and processing words than those carried to full-term, likely because brain regions that process sounds aren’t sufficiently developed at the time of delivery. Now, an unusual study with 40 preemies suggests that recreating a womblike environment with recordings of a mother's heartbeat and voice could potentially correct these deficits.
