Phytoplankton bloom in the Black Sea

An intense bloom of phytoplankton continued in the Black Sea in early June, 2012, staining nearly every corner of the 436,400 km2 (168,500 sq. mi) Sea with a rich palette of teal, turquoise, green and milky blue.

THEY can "smell" chemicals and respond to light, but can plants hear sounds? It seems chilli seeds can sense neighbouring plants even if those neighbours are sealed in a box, suggesting plants have a hitherto-unrecognised sense.

Scientists at Bristol University used powerful loudspeakers to listen to corn saplings – and heard clicking sounds coming from their roots. When they suspended their roots in water and played a continuous noise at a similar frequency to the clicks, they found the plants grew towards it.

Maybe Prince Charles was right after all: British scientists reveal plants really do talk »

New research suggests plants not only respond to sound but communicate with each other with ‘clicking’ noises.

"Scientists were unsure what this would mean for our galaxy in the long-term. Would we collide directly with Andromeda, a galaxy roughly the size as our Milky Way? Or would we slide past it, like two ships passing in the night?"+NASA  #science   #space

The Hubble Space Telescope shows that we're on a collision course with the nearby Andromeda galaxy—and set to crash in about 4 billion years

Homo Erectus - Planet of the Apemen: Battle for Earth - BBC

Homo Erectus - Planet of the Apemen: Battle for Earth - BBC This episode is set 75,000 years ago in India, following a catastrophic super-volcanic eruption which forced a showdown between our ancestors and a completely different species of human, Homo erectus, who up until that point had reigned supreme. Homo erectus was a successful, long-lived species that migrated out of Africa. Possibly the first humans to live in hunter-gatherer societies, they also used rafts to travel the oceans.
