Controlling mosquito populations through genetic breeding      (via sciencedaily.com)     Original source 

Researchers have found a new way to identify genetic targets useful for control of mosquito populations, potentially offering an alternative to insecticides. Their study focused on the genetic basis of species incompatibility. They crossed Ae. aegypti, a major global arboviral disease vector, and its sibling species, Ae. mascarensis, from the Indian Ocean. When offspring is crossed back with one parent, about 10 percent of the progeny becomes intersex and is unable to reproduce.

3D printing of light-activated hydrogel actuators      (via sciencedaily.com)     Original source 

An international team of researchers has embedded gold nanorods in hydrogels that can be processed through 3D printing to create structures that contract when exposed to light -- and expand again when the light is removed. Because this expansion and contraction can be performed repeatedly, the 3D-printed structures can serve as remotely controlled actuators.

Chimpanzees gesture back and forth quickly like in human conversations      (via sciencedaily.com)     Original source 

When people are having a conversation, they rapidly take turns speaking and sometimes even interrupt. Now, researchers who have collected the largest ever dataset of chimpanzee 'conversations' have found that they communicate back and forth using gestures following the same rapid-fire pattern.

Life signs could survive near surfaces of Enceladus and Europa      (via sciencedaily.com)     Original source 

Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.

Waste Styrofoam can now be converted into polymers for electronics      (via sciencedaily.com)     Original source 

A new study describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known as PEDOT:PSS. Researchers also noted that the upgraded plastic waste can be successfully incorporated into functional electronic devices, including silicon-based hybrid solar cells and organic electrochemical transistors.

'Secret' hidden structure paves new way of making more efficient and stable perovskite solar cells      (via sciencedaily.com)     Original source 

Researchers has revealed the existence of surface concavities on individual crystal grains -- which are the fundamental blocks -- of perovskite thin films, and have unraveled their significant effects on the film properties and reliability. Based on this discovery, the team pioneered a new way of making perovskite solar cells more efficient and stable via a chemo-elimination of these grain surface concavities.

Converting wastewater to fertilizer with fungal treatment      (via sciencedaily.com)     Original source 

Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temperature, high-pressure process. Two studies explore the use of a fungal treatment to convert the leftover wastewater into fertilizer for agricultural crops.

Novel electrode for improving flowless zinc-bromine battery      (via sciencedaily.com)     Original source 

The flowless zinc-bromine battery (FLZBB) is a promising alternative to flammable lithium-ion batteries due to its use of non-flammable electrolytes. However, it suffers from self-discharge due to the crossover of active materials, generated at the positive graphite felt (GF) electrode, to the negative electrode, significantly affecting performance. Now, researchers have developed a novel nitrogen-doped mesoporous carbon-coated GF electrode that effectively suppresses self-discharge. This breakthrough can lead to practical applications of FLZBB in energy storage systems.

Ant insights lead to robot navigation breakthrough      (via sciencedaily.com)     Original source 

Have you ever wondered how insects are able to go so far beyond their home and still find their way? The answer to this question is not only relevant to biology but also to making the AI for tiny, autonomous robots. Drone-researchers felt inspired by biological findings on how ants visually recognize their environment and combine it with counting their steps in order to get safely back home. They have used these insights to create an insect-inspired autonomous navigation strategy for tiny, lightweight robots. It allows such robots to come back home after long trajectories, while requiring extremely little computation and memory (0.65 kiloByte per 100 m). In the future, tiny autonomous robots could find a wide range of uses, from monitoring stock in warehouses to finding gas leaks in industrial sites.
