Piton de la Fournaise Eruption Update for 10/15/2010
We now have some more information (Note: pretty much all the information on this eruption is in French) - and more importantly, some great images - of the eruption that is ongoing at Piton de la Fournaise on Reunion Island. The volcano erupted yesterday evening (local time on Reunion Island) and it seems that like the fall 2009 eruption that was clearly a new fissure vent eruption, this eruption is also sourced from a fissure vent (see below) - some of which has coalesced into three fountains/spatter cones along the fissure - see more images of the fissure. The eruption is thought to be a new dike intruding directly under the summit Dolomieu Crater, thus its location and geometry. All in all, this seems a fairly typical eruption for the hotspot volcano - low viscosity mafic lava erupting in fissures, producing lava flows or spatter cones - you can't get much more "Hawaiian" than that. The webcam "Vue depuis Piton de Bert" captures some of the activity from the new eruption.

Research in plant neurobiology shows that plants have senses, intelligence and emotions.
- The field of plant neurobiology studies the complex behavior of plants.
- Plants were found to have 15-20 senses, including many like humans.
- Some argue that plants may have awareness and intelligence, while detractors persist.
Most people think human extinction would be bad. These people aren't philosophers.
- A new opinion piece in The New York Times argues that humanity is so horrible to other forms of life that our extinction wouldn't be all that bad, morally speaking.
- The author, Dr. Todd May, is a philosopher who is known for advising the writers of The Good Place.
- The idea of human extinction is a big one, with lots of disagreement on its moral value.
Since the idea of locality is dead, space itself may not be an aloof vacuum: Something welds things together, even at great distances.
- Realists believe that there is an exactly understandable way the world is — one that describes processes independent of our intervention. Anti-realists, however, believe realism is too ambitious — too hard. They believe we pragmatically describe our interactions with nature — not truths that are independent of us.
- In nature, properties of Particle B may depend on what we choose to measure or manipulate with Particle A, even at great distances.
- In quantum mechanics, there is no explanation for this. "It just comes out that way," says Smolin. Realists struggle with this because it would imply certain things can travel faster than light, which still seems improbable.
