The antibiotic cocktail produced by symbiotic bacteria changed very little in the course of evolution and its antipathogenic effect remained unaltered — ScienceDaily

The discovery of penicillin about 90 years ago and the widespread introduction of antibiotics to combat infectious diseases have revolutionized human medicine. However, in recent decades, the increase in multidrug-resistant pathogens has confronted modern medicine with massive problems. Insects have their own antibiotics, which provide natural protection against germs. A team of scientists from the Johannes Gutenberg University in Mainz and the Max Planck Institute for Chemical Ecology in Jena have now found that beewolves, unlike humans, do not face…

Scientists image molecules vital for gene regulation — ScienceDaily

All the trillions of cells in our body share the same genetic information and are derived from a single, fertilized egg. When this initial cell multiplies during fetal development, its daughter cells become more and more specialized. This process, called cell differentiation, gives rise to all the various cell types, such as nerve, muscle, or blood cells, which are diverse in shape and function and make up tissues and organs. How can the same genetic blueprint lead to such diversity?…

Highly stretchable aqueous batteries — ScienceDaily

The current development of stretchable battery materials that mimic the functions of nature has emerged as a highly interesting research area, necessary for the next wave of wearable electronics. A recent study, affiliated with UNIST has presented a bioinspired Jabuticaba-like hybrid carbon/polymer (HCP) composite that was developed into a stretchable current collector using a simple and cost-effective solution process. Using the HCP composite as a stretchable current collector, the research team has, for the first time, developed a highly stretchable…

Drying and dehydration—solutions to address global food shortage

Investigating retention of food nutrients during drying. Credit: University of Nottingham In the University of Nottingham Malaysia, a team of chemical and food engineers from the Food and Pharmaceutical Engineering Research Group are investigating drying and dehydration of various food materials using advance dryers. In food processing, drying plays a critical role in food preservation and safe consumption as most food products contain high moisture content which can deteriorate fast under room temperature. If food is not preserved properly, this…

Fungi can help concrete heal its own cracks

Could a secret ingredient make crumbling concrete a thing of the past? Credit: m_e_mccarron, CC BY-SA Infrastructure supports and facilitates our daily lives – think of the roads we drive on, the bridges and tunnels that help transport people and freight, the office buildings where we work and the dams that provide the water we drink. But it’s no secret that American infrastructure is aging and in desperate need of rehabilitation. Concrete structures, in particular, suffer from serious deterioration. Cracks…

Accessible Colors for Data Visualization – Square Corner Blog – Medium

Part 1: Open-source style guide. A good graph is easy to read. A goal when creating data visualizations is to convey information in a clear and concise way. One of the most prominent features of most data visualizations is color, but what happens to a graph for someone who has difficulty differentiating colors? For example, an orange and green color that may appear separate to some could appear nearly identical to individuals with protanopia vision, a type of colorblindness. A GIF…

Flexible bonding—hard and soft at the same time

MetAK enables scoliosis corsets in new, modern designs with a high level of wearing comfort. Credit: Fraunhofer LBF To connect components with each other, gluing is preferred today instead of welding, riveting or using screws. That makes cars, planes and agricultural machines lighter. The requirements placed on the adhesive are high, though: it has to be flexible enough to compensate for stress peaks in the joint zone while still providing a rigid connection in the surface. Fraunhofer researchers have now…

Air Purifier: Combat Air Pollution at Your Home

As we live in this polluted world, what is that one thing we care for more than anything else? It’s Clean Air. Yes, this is one important basic aspect of our life which is possibly lacking in our surroundings, offices or homes. Even today, we seek fresh air somewhere far from urban areas i.e. in woods or mountains. But do you wonder if we are actually safe in our homes? Stale air, suspended dust and dust mites give rise to…

A phospholipid pathway from plants to parasites — ScienceDaily

Recent findings by researchers at Washington University in St. Louis may aid in the development of therapies to treat parasitic infections, including malaria, and may help plant scientists one day produce hardier crops. The research team’s work is published in the Dec. 29 issue of the Journal of Biological Chemistry. Choline is an essential nutrient that humans get from certain foods, including eggs, meat, leafy greens and nuts. The human body converts choline into phosphocholine (pCho), which it in turn…
