Creating a hotspot for understanding Venus
A new simulation facility at the Planetary Spectroscopy Laboratory of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) could help revolutionise our understanding of the hot, hidden surface of Venus. The Planetary Spectroscopy Laboratory (PSL) can analyse rock samples similar to those found on the surface of Venus at temperatures up to 1000 degrees Celsius, enabling researchers to interpret accurately data acquired by space missions and ground-based observations.

A first look at how miniscule bubbles affect the texture of noodles
The texture of a noodle is a remarkably complicated thing. When you bite into a spoonful of ramen noodles, you expect a bit of springiness (or a resistance to your bite) on the outside and a pleasantly soft give on the interior. These variations are so tiny as to be often overlooked, but they matter to noodle quality.

Influence of carbon dioxide leakage on the seabed
Storing carbon dioxide (CO2) deep below the seabed is one way to counteract the increasing concentration of CO2 in the atmosphere. But what happens if such storage sites begin to leak and CO2 escapes through the seafloor? Answers to this question have now been provided by a study dealing with the effects of CO2 emissions on the inhabitants of sandy seabed areas.

Devoted frog fathers guard their eggs from predators
A study led by Ph.D. candidate Mr K. S. Seshadri from the Department of Biological Sciences at the National University of Singapore's Faculty of Science has revealed that male white-spotted bush frogs (Raochestes chalazodes) dedicatedly guard their fertilised eggs from other cannibalistic male frogs and predators. The study confirmed that the adult male white-spotted bush frogs are the sole caregivers of their offspring, predominantly by attending to and guarding the eggs.

Scientists identify pheromone from insect that transmits citrus greening (HLB)
The Asian citrus psyllid Diaphorina citri is only 2 mm long, yet it strikes terror into the hearts of citrus growers in Brazil, China and the United States. This is because it acts as a vector for the bacteria that causes Huanglongbing (HLB), commonly known as citrus greening. HLB originated in Asia and now affects most citrus groves worldwide. The disease is devastating for the citrus industry because infected trees must be eradicated.

Mathematics pushes innovation in 4-D printing
Recent advances in digital factory science make it possible to print more compliant objects across a wider range of length-scales than conventional engineering processes. A bottleneck for enabling the next technological progress resides in filling the gap in the comprehension of the unprecedented degree of complexity dominating this novel technology.
