Earth may be 140 years away from reaching carbon levels not seen in 56 million years  

Total human carbon dioxide emissions could match those of Earth's last major greenhouse warming event in fewer than five generations, new research finds. A new study finds humans are pumping carbon dioxide into the atmosphere at a rate nine to 10 times higher than the greenhouse gas was emitted during the Paleocene-Eocene Thermal Maximum (PETM), a global warming event that occurred roughly 56 million years ago.

Blueprint for treating a deadly brain tumor

The results suggested that certain patients' tumor cells are less aggressive and much better at repairing DNA than others but are difficult to kill with radiation. The researchers then showed that combining radiation therapy with cancer drugs designed to block DNA repair may be an effective treatment strategy.

Lobster's underbelly is as tough as industrial rubber  

Flip a lobster on its back, and you'll see that the underside of its tail is split in segments connected by a translucent membrane that appears rather vulnerable when compared with the armor-like carapace that shields the rest of the crustacean.
