An enzyme that could represent a powerful new tool for combating Alzheimer's disease has been discovered by researchers at Mayo Clinic in Florida. The enzyme — known as BACE2 — destroys beta-amyloid, a toxic protein fragment that litters the brains of patients who have the disease. The findings were published online Sept. 17 in the science journal Molecular Neurodegeneration.

Eight billion years ago, rays of light from distant galaxies began their long journey to Earth. That ancient starlight has now found its way to a mountaintop in Chile, where the newly-constructed Dark Energy Camera, the most powerful sky-mapping machine ever created, has captured and recorded it for the first time.

That light may hold within it the answer to one of the biggest mysteries in physics – why the expansion of the universe is speeding up.
