Phys.org / Beyond the habitable zone: Exoplanet atmospheres are next clue to finding life on planets orbiting distant stars

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to its star, water on its ...

Phys.org / Hunting for 'wandering' black holes in dwarf galaxies

Tracking down black holes at the center of dwarf galaxies has proven difficult. In part it is because they have a tendency to "wander" and are not located at the galaxy's center. There are plenty of galaxies that might contain ...

Phys.org / How bacteria 'feel' surfaces: Fluorescent probe visualizes and quantifies membrane tension

In natural environments, bacteria rarely live as free-swimming cells but are attached to surfaces as biofilms in medical devices, mobile phones or human tissue. The bacterial behavior, how they attach and grow, group together ...
