'Meta-mirror' reflects sound waves in any direction

Researchers have constructed a 'meta-mirror' device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror and only seeing the person next to you instead of your own face.

How antifreeze proteins make ice crystals grow

Bacteria, plants, insects, or even fish use antifreeze proteins to protect themselves from the cold. The proteins block the growth of ice crystals. In a new study, researchers have confirmed that these proteins also possess an unusual second property: at low temperatures, they can promote rather than inhibit the growth of ice crystals.

Chimpanzees lose their behavioral and cultural diversity

Chimpanzees are well known for their extraordinary diversity of behaviors, with some behaviors also exhibiting cultural variation. An international research team has investigated whether chimpanzee behavioral diversity is reduced under high human impact. By comparing sets of chimpanzee behaviors across a large number of social groups exposed to different levels of human disturbance, the scientists found a reduction in behavioral diversity when human impact was high.

What does the Milky Way weigh? Hubble and Gaia investigate

We can't put the whole Milky Way on a scale, but astronomers have been able to come up with one of the most accurate measurements yet of our galaxy's mass, using NASA's Hubble Space Telescope and the European Space Agency's Gaia satellite.

Chemical hydrogen storage system

Hydrogen is a highly attractive, but also highly explosive energy carrier, which requires safe, lightweight and cheap storage as well as transportation systems. Scientists have now developed a chemical storage system based on simple and abundant organic compounds. The liquid hydrogen carrier system has a high theoretical capacity and uses the same catalyst for the charging-discharging reaction.

Spectroscopy on individual molecules

While spectroscopic measurements are normally averaged over myriad molecules, a new method provides precise information about the interaction of individual molecules with their environment. This will accelerate the identification of efficient molecules for future photovoltaic technologies, for example.
