What are the best ways to search for technosignatures?

The search for extraterrestrial intelligence (SETI) has long roots in human history. With the advent of modern technologies, scientists were finally able to start scanning the skies for any sign of life. When the search ...

Discovery could lengthen lifespan of electronic devices

Nobel laureate Herbert Kroemer once famously asserted "The interface is the device." The observations by the Sydney researchers could therefore spark a new debate on whether interfaces—which are physical boundaries separating ...

Learning what makes the nucleus tick

Michigan State University's Witold Nazarewicz has a simple way to describe the complex work he does at the Facility for Rare Isotope Beams, or FRIB.

Better solutions for making hydrogen may lie just at the surface

A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That's because, even though hydrogen is abundant, it must be derived from another substance that contains ...

Scientists successfully breed corals in the lab

Scientists at the University of Oldenburg's Institute for Chemistry and Biology of the Marine Environment (ICBM) have scored a success: in the aquariums at the ICBM's Wilhelmshaven site they were able to induce sexual reproduction ...

How nitrate regulates gene expression in legumes

Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful (Figure 1), but precisely how nitrate presence controls nodule formation ...
