Scientists at Stanford University in California found that when a bleached coral fragment makes contact with a healthy one, the dying fragment can make a full recovery. (Danny Collins)The best medicine for a dying coral may be the power of touch. Scientists at Stanford University in California stumbled on a promising discovery when two coral fragments in the lab — one bleached and one healthy — tipped over in a tank and touched.

The oceans are in trouble. Rising temperatures due to climate change not only raise sea levels but also put enormous stress on coral reefs. When waters get too warm, healthy coral will expel the helpful algae living inside them. The coral then becomes drained of color, severely weakened, and vulnerable to disease. In other words, "bleached coral" is dying coral. The loss of coral and coral reefs devastates vast amounts of ocean wildlife, and humans too. So finding ways to stop, slow, or reverse coral bleaching is of major interest to scientists. And the latest breakthrough was completely unintentional. Lab studying coral encounters a "happy accident"Steve Palumbi is a professor of marine sciences at Stanford and an ocean researcher. One of his major research areas is coral, and his work recently led him to notice something pretty strange in his lab. According to Science Alert, Palumbi had collected various samples from the same coral colony when two of the samples "fell" into each other inside their tank. One was bleached, or dying, and the other was completely healthy.

Dinosaurs might have been beachcombers that dined on washed-up seafood, researchers report. Researchers looked at carbon isotope traces in fossilized teeth and bones from coastal-dwelling dinosaurs and found a signature that could be linked to the consumption of seafood. The work highlights the connections terrestrial and marine ecosystems have had for millions of years.
