Ferns" ancient resilience aids modern ecosystem recovery after disasters
Scientists have suggested an updated framework for the role of ferns in environmental recovery from disaster. Instead of competing with other organisms, ferns may act as facilitators that ease the way for other plants and animals to re-establish them.....»»
Volunteers should not become friends with patients, say Norwegian researchers
When a volunteer supports a patient, a special and often rather unequal relationship can develop between the helper and the person receiving the help. Researchers have now investigated this relationship and offer guidance on finding the right balance.....»»
Avalanches, icy explosions and dunes: NASA is tracking New Year on Mars
Instead of a winter wonderland, the Red Planet's northern hemisphere goes through an active—even explosive—spring thaw. While New Year's Eve is around the corner here on Earth, Mars scientists are ahead of the game: The Red Planet completed a tri.....»»
Intense ribbons of rain also bring the heat, scientists say
The environmental threat posed by atmospheric rivers—long, narrow ribbons of water vapor in the sky—doesn't come only in the form of concentrated, torrential downpours and severe flooding characteristic of these natural phenomena. According to a.....»»
Scientists steer the development of stem cells to regenerate and repair organs
Investigators from Cedars-Sinai and the University of California, San Francisco (UCSF) have identified a new way to deliver instructions that tell stem cells to grow into specific bodily structures, a critical step in eventually regenerating and repa.....»»
