New lava flows from Erta'Ale

There hasn't been a lot of coverage in the news, but Ethiopia's Erta'Ale has started issuing new lava flows over the last week. I got a note from an Eruptions reader who is near the volcano that offers some details:

Just back a couple of days ago from Erte Ale on one of Tom Pheifers Volcano Discovery Tours, and Erte Ale has begun to have lava flows.The lava lake often boiled over causing small flows. The pit has grownup and now sits about 20m above the old one with lava right at the surface.

There are also a report from the Leeds University Afar Rift Consortium that mentions the new lava flows - with images of lava flows and samples taken from these new eruptive products, all from November 21-23. It seems pretty clear that the lava lake in the crater of the volcano is very active, with lava flows coming from breaches in the lake and small spatter cones/ramparts forming from the fountaining of the low viscosity basalt magma. Especially evident is how much the crater lake area has filled with lava since February 2010 (see below). All this activity is part of the ongoing activity at Erta'Ale that started in 1967 - and all part of the Eastern African Rift.

Do you have a self-actualized personality? Maslow revisited

Rediscovering the principles of self-actualisation might be just the tonic that the modern world is crying out for.

Personal Growth

Abraham Maslow was the 20th-century American psychologist best-known for explaining motivation through his hierarchy of needs, which he represented in a pyramid. At the base, our physiological needs include food, water, warmth and rest.

Scientists reactivate cells from 28,000-year-old woolly mammoth

"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."

Yamagata et al.
Surprising Science
  • The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
  • Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
  • Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.

Believe in soulmates? You're more likely to 'ghost' romantic partners.

Does believing in true love make people act like jerks?

Sex & Relationships
  • Ghosting, or cutting off all contact suddenly with a romantic partner, is not nice.
  • Growth-oriented people (who think relationships are made, not born) do not appreciate it.
  • Destiny-oriented people (who believe in soulmates) are more likely to be okay with ghosting.
