Astronomers discover strangely massive black hole in Milky Way satellite galaxy

Astronomers have discovered an unusually massive black hole at the heart of one of the Milky Way's dwarf satellite galaxies, called Leo I. Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all galaxies -- the building blocks of the universe -- evolve.

The diabetes medication that could revolutionize heart failure treatment

A medication originally used for patients with diabetes is the first to help people with heart failure and could revolutionize treatment. Early research had shown that SGLT2 inhibitors could help around half of heart failure patients -- those with a condition known as reduction ejection fraction. But a new study shows that the medication could be beneficial for all heart failure patients -- including those with a second type of heart failure called preserved ejection fraction.

3D laser nanoprinters become compact

Lasers in conventional laser printers for paper printouts are very small. 3D laser printers for 3-dimensional microstructures and nanostructures, by contrast, have required big and expensive laser systems so far. Researchers now use another process for this purpose. Two-step absorption works with inexpensive and small, blue laser diodes. As a result, much smaller printers can be used.

Diversity of the gut microbiome in gorillas

A new study sheds light on the gut microbiome of gorillas, moving researchers closer to developing tools that can use the microbiome to diagnose potential health challenges for gorillas in human care. Specifically, the study found significant diversity among gorilla microbiomes, suggesting that what constitutes a 'healthy' microbiome can vary between individuals.
