New insights on dark energy

The universe is not only expanding - it is accelerating outward, driven by what is commonly referred to as "dark energy." The term is a poetic analogy to label for dark matter, the mysterious material that dominates the matter ...

Fast radio bursts may be firing off every second

When fast radio bursts, or FRBs, were first detected in 2001, astronomers had never seen anything like them before. Since then, astronomers have found a couple of dozen FRBs, but they still don't know what causes these rapid ...

One-way track for microwaves based on mechanical interference

Devices that allow to route microwave signals are essential engineering tools. In particular, isolators, which let signals flow in one direction but block them in the other, are needed to protect sensitive equipment from ...

NASA satellite images show evolution of Hurricane Harvey

Hurricane Harvey continues to churn toward the Texas coast, and is expected to make landfall as a major hurricane sometime late Aug. 25 or early Aug. 26, according to the National Hurricane Center. It would be the first major ...

Using microwaves to break up rock saves energy

In a project funded by the Austrian Science Fund FWF, a research group from Leoben investigated how excavation methods for hard rock could be improved by using microwave irradiation so as to make classical mechanical excavation ...

NASA's scientific balloon program reaches new heights

For decades, NASA has released enormous scientific balloons into Earth's atmosphere, miles above the altitude of commercial flights. The Balloon Program is currently preparing new missions bearing sensitive instruments, including ...
