It's about time that we had a thread devoted to cool science news. I'm always seeing interesting articles about various science related news and I know I'm not seeing half of what's out there. Let's kick it off with this tough bug:

TOKYO (AP) — Scientists have discovered the ultimate case of regeneration: Some decapitated sea slugs can regrow hearts and whole new bodies.

This “wonder of nature,” reported in a biology journal on Monday, could eventually help scientists better understand and tackle regeneration of human tissue.

Biology researcher Sayaka Mitoh said she loves studying Japanese sea slugs because they are small, cute and weird. They can even briefly photosynthesize like a plant drawing food from the sun.

One day in the lab, she saw something bizarre: A sea slug had decapitated itself and the head kept on moving and living. Then a couple more did the same, according to a study in Current Biology.

So the doctoral student and Nara Women’s University aquatic ecology professor Yoichi Yusa tried it themselves, cutting the heads off 16 sea slugs. Six of the creatures started regeneration, with three succeeding and surviving. One of the three even lost and regrew its body twice. Two different species of Japanese sea slugs did this regeneration trick.............

Heads up: Some sea slugs grow new bodies after decapitation (apnews.com)

If you are the deadliest snake in the world, don't challenge a mongoose.

Us mammals are a trippy bunch. We've got bats, who can outfly a moth. Mongooses who're faster than a cobra, and otters that can outswim a trout.

The Indian astrophysicists used a technique called singular value decomposition method, as against the standard spectral estimation approach that was used in discovering the uniform red shift that supports Big Bang theory. “The superiority of the singular value decomposition method in analysing red shift periodicity, especially from the point of view of robustness, is demonstrated through the simulations. We took very large data samples and used a statistical method, which is more robust than the method usually dealt with by astronomers,” Prof Roy said.

Interestingly, although this is not the first time that the Big Bang theory has been challenged, the previous challenges were based on much smaller sample sizes. The Steady State Theory, Gravitational Lending Model, Tired Photon Hypothesis, Variable Mass Hypothesis have all challenged the Big Bang theory in the past.“But the problem with each of them was the sample size. The renowned physicist, late Stephen Hawking, and his collaborators had stated that the criticism levelled against the theories challenging the Big Bang is because the samples of red shifts that were analysed were rather small and selected in a heterogeneous manner, which made it hard to assess their significance,” Prof Roy said.

This also explains why businesses turn people against unions, politicians divide constituents, and one should generally avoid large crowds of people.
I'm a nature nerd. One of my favorite sayings is beware of the herbivores. The Hippo kills more people in Africa than any carnivore.

Mama said that herbivores are so ornery because they have all of those teeth but no toothbrush.
