European eels transmit a herpesvirus through bites, revealing another route for fish infections
Contrary to what was previously believed, viruses infecting fish are not transmitted exclusively through water acting as an abiotic vector. A team of researchers from the University of Liège has demonstrated that a virus affecting European eels can spread very efficiently through

Microscopy upgrade sharpens images fivefold without sacrificing tissue imaging depth
Researchers at Texas A&M University have cracked a problem that has limited biological imaging for years: seeing fine cellular detail while looking deep inside living tissue. The new microscopy technique resolves structures smaller than 100 nanometers, roughly a thousand times th

By carefully arranging molecules, scientists can control how a material responds to light, heat and physical force
University of Missouri researchers have created a single solid material that responds differently depending on what it's exposed to. Shine light on it, and it changes from yellow to white, an indication of a chemical reaction. Heat it, and it undergoes a different chemical reacti

How the cosmic environment depletes galaxies of their gas
An international team of researchers, led by Jonathan Freundlich (University of Strasbourg, Astronomical Observatory), has revealed how a dense cosmic environment depletes galaxies of their gas. By mapping the molecular gas in a galaxy group located 7 billion light-years away, th

Earliest known compact quasar pair poses a black hole growth puzzle
The oldest pair of compact quasars ever observed has been found only 900 million years after the Big Bang. Scientists say there is no theoretical explanation for how the pair of actively feeding black holes grew so massive at such an early time in the history of the universe. The
