Giant tortoises gain a foothold on a Galapagos Island
A population of endangered giant tortoises, which once dwindled to just over a dozen, has recovered on the Galapagos island of Espanola, a finding described as 'a true story of success and hope in conservation' by the lead author of a study published today (Oct. 28).

The chemistry of death (video)
It's a spooky question, but it doesn't have to be: What happens when you die? Even after you depart, there's a lot of chemistry that still goes on inside you. Reactions teamed up with mortician Caitlin Doughty, author of the new book 'Smoke Gets in your Eyes, and Other Lessons from the Crematory' to demystify death and talk about exactly what happens to the body postmortem. Check out the new episode here: http://youtu.be/BpuTLnSr_20.
Icelandic volcano sits on massive magma hot spot
New research from University of California Davis and Aarhus University in Denmark shows that high mantle temperatures miles beneath the Earth's surface are essential for generating large amounts of magma. In fact, the scientists found that Iceland's Bardarbunga volcano lies directly above the hottest portion of the North Atlantic mantle plume.

Kung fu stegosaur
Stegosaurs might be portrayed as lumbering plant eaters, but they were lethal fighters when necessary, according to paleontologists who have uncovered new evidence of a casualty of stegosaurian combat. The evidence is a fatal stab wound in the pubis bone of a predatory allosaur. The wound -- in the conical shape of a stegosaur tail spike -- would have required great dexterity to inflict and shows clear signs of having cut short the allosaur's life.
Sweet science: How chemistry makes your treats sweet (video)
It's National Chemistry Week, and this year's theme is the sweetest of all: candy. Whether it's ice cream, candy bars, pudding or cake, we love our sweets. But why do those treats actually taste sweet? Whether they're made with sugar or artificial sweeteners, it all comes down to chemistry. Find out more here: http://youtu.be/FaBFyEa8-eI.
Two Michigan high school students develop screening tools to detect lung and heart disease
Two Michigan high school students, sisters Ilina and Medha Krishen, have developed screening tools using electronic stethoscopes to detect lung and heart disease. The sisters will present their findings at CHEST 2014 in Austin, Texas next week.
These roos were 'made' for walking, study suggests of extinct enigmas
Based on a rigorous comparative analysis of kangaroo anatomy, researchers posit that the ancient family of sthenurine kangaroos that lived until 30,000 years ago likely preferred walking to hopping.
The chemistry of pizza (video)
Whether it's a plain cheese, a deep-dish stacked with meats or a thin-crust veggie delight, there's just something about pizza that makes it delicious. There's a lot of chemistry that goes into everything from dough to sauce to toppings to, of course, cheese. There's also a very specific chemical reaction at work on every single slice, no matter what toppings you choose. Check out the latest episode here: http://youtu.be/tOkCgAwhh9U.

Migrating animals' pee affects ocean chemistry
Tiny animals migrating from the ocean's surface to the sunless depths release ammonia, the equivalent of our urine, that plays a significant role in marine chemistry, particularly in low-oxygen zones.

Hungry black hole eats faster than thought possible
Astronomers have discovered a black hole that is consuming gas from a nearby star 10 times faster than previously thought possible. The black hole -- known as P13 -- lies on the outskirts of the galaxy NGC7793 about 12 million light years from Earth and is ingesting a weight equivalent to 100 billion billion hot dogs every minute.
