Scientists have discovered that a mouse found in Africa can lose large patches of skin and then grow it back without scarring, perhaps as a way of escaping the clutches of a predator.
The finding challenges the conventional view that mammals have an extremely limited ability to replace injured body parts. There are lizards that can regrow lost tails, salamanders that can replace amputated legs, and fish that can generate new fins, but humans and other mammals generally patch up wounds with scar tissue.
This spectacular image of the large spiral galaxy NGC 1232 was obtained by the European Southern Observatory's Very Large Telescope (VLT) in 1998. NGC 1232 sits in the constellation Eridanus (The River) at a distance of about 100 million light-years and is about twice the size of the Milky Way galaxy.
Where does the Universe end? Or, to put it differently, does the Universe have an edge? When cosmologists say that the Universe is expanding, people tend to think of an exploding bomb. They see galaxies as shrapnel, flying off in all directions. Even if intuitive, this image is dead wrong.
The cosmic expansion is an expansion of space itself. Since Einstein's theory of general relativity, space has been endowed with a plasticity that allows it to expand, shrink or fold like a rubber balloon in response to the presence of matter (and energy).
Jazz multi-instrumentalist Sam Rivers, who died at 88 in December 2011, recorded with many trios in the 1970s. But his most celebrated trio was barely recorded at all. In 2007, it played a reunion concert — its first in 26 years.

In the fairy-tale world, a shiny red apple can lead to a poisonous end. But some see two genetically engineered green apple varieties, poised to become the first to gain U.S. Department of Agriculture approval,as similar harbingers of doom.
Uruguayan lawmakers have very narrowly approved a bill allowing women limited access to abortion. As the Los Angeles Times reports, it's a big change for a country that outlaws the procedure. Should it take effect, Uruguayan women can legally terminate their pregnancies in the first 12 weeks.
People are not getting much work done in parts of Europe. Last night, there were violent protests in Spain. They were protests against austerity measures, which is also the case in Greece, where a nationwide strike came today. It closed businesses and schools, and reporter Joanna Kakissis is following the story from Athens.

A view of Ranthambore National Park from atop the thousand-year-old fort that bears the same name. The park has been closed to visitors since the Supreme Court's ban on tourists in core areas of the country's 41 tiger reserves. A quarter-million visitors toured the park last year, and local businesses say the economy in the area will collapse if the ban is not lifted.
Can tigers and tourists coexist? The debate is rumbling through India, where the Supreme Court has temporarily banned tourism in core areas of the country's 41 tiger reserves. The unexpected and controversial ruling is aimed at protecting the last of India's 1,700 tigers.
Up until the late 1960s, big game hunters trod the forests of Rajasthan's Ranthambore National Park, part of a sprawling tiger reserve southwest of Delhi. Under the court's recent ban, spotting one of India's big cats — a tiger or the more elusive leopard — inside the park is forbidden.
