Flowery diets help predatory insects help farmers keep pests in check

Good news for the green transition: Flowery diets help predatory insects help farmers keep pests in check Predatory insects have been shown to live longer when they have access to nectar and pollen, according to a new study by researchers at the University of Copenhagen. Thus, flowers don’t just benefit…

Cargo delivery by polymers | EurekAlert! Science News

Degradable, bio-based polymers offer options for chemical recycling, and they can be a tool to store and release useful molecules. Scientists have developed a class of sugar-based polymers that are degradable through acid hydrolysis. The researchers also integrated “cargo” molecules in the polymer, which are designed to split off after…

Pancreatic β cell-derived exosomal miR-29 family enhances hepatic glucose output

In a new study published in Journal of Extracellular Vesicles, Chen-Yu Zhang’s group at Nanjing University, School of Life Sciences, and Antonio Vidal-Puig’s group at University of Cambridge report that pancreatic β cells secrete miR-29 family members (miR-29s) via exosomes in response to high levels of free fatty acids (FFAs)….

Magnetic waves explain mystery of Sun’s outer layer

The Sun’s extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades. One explanation is that, in the middle layer (the chromosphere), magnetic waves exert a force that separates the Sun’s plasma into…

Targeted coating improves graphene oxide membranes for nanofiltration

Nanofiltration (NF) is an advanced technology for treating wastewater containing organic micropollutants (OMPs). Recently, a research group led by Prof. WAN Yinhua from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences developed a stable graphene oxide nanofiltration membrane with uniform pore size to remove OMPs. The…

Study recommends rugby league invests in young players’ diets

Young rugby league players could benefit from individualised nutrition plans to maximise performance and optimise recovery throughout their careers, according to QUT researchers. The new study, published in the International Journal of Sport Nutrition and Exercise Metabolism, provides nutritional recommendations and considers potential supplements to improve players’ physical capacity, health…
