Going to Mars is hard: Lessons from Mariner 9

Fifty years ago this weekend, NASA's Mariner 9 probe went into orbit around Mars. This pioneering mission revolutionized our ideas about Mars and, with humans looking to head that way, is a timely reminder of just how utterly inhospitable a place it is.

Blood biomarker predicts type 2 diabetes risk up to 19 years before onset

A study is proposing blood levels of a specific protein may serve as a predictor of type 2 diabetes up to almost two decades before any symptoms appear. The findings indicate a blood test could offer a way to assess future risk of developing the disease.

How the universe’s expansion may have stopped dark matter taking over

How did the universe end up with exactly the amount of dark matter needed? A new model suggests dark matter particles in the early universe converted regular matter into dark matter exponentially, before being slowed by the expansion of the universe.
