Expert Advice: Traveling by Airplane With COPD

Given the growing population of individuals reaching advanced age, it is anticipated that more people with medical conditions will travel by air. This projection underscores the need for healthcare providers and patients to be knowledgeable about adequate preparation for air travel to minimize the risk for adverse events.

An estimated 12% of in-flight emergencies are attributed to respiratory illnesses, and chronic obstructive pulmonary disease (COPD) has been cited as the most common reason for pre-flight medical screening.

More Insights: Ion Channels Added to the Brain Remote Control

By enabling super-fast remote control of specific cells, light-activated proteins allow researchers to study the function of individual neurons within a large network. Now one of the pioneers of 'optogenetics' and colleagues have created two new tools—protein pores which when illuminated allow Ca2+ into cells or K+ out—for switching neurons on or off using light. Published in Frontiers in Neuroscience, their study shows that these synthetic 'ion channels' can be used to control specific neurons, even in live animals.

Disease Surveillance: Potential Role of Bioaerosol Sampling

A pilot study shows that non-invasive bioaerosol sampling and molecular diagnostics can detect respiratory viruses in aerosol samples in public places such as Singapore's MRT trains. Findings support possibility of employing bioaerosol samplers in crowded areas of densely populated cities like Singapore facing heightened risk from global pandemics.

Study: Artificial Synapses Made from Nanowires

Scientists have produced a memristive element made from nanowires that functions in much the same way as a biological nerve cell. The component is able to both save and process information, as well as receive numerous signals in parallel. The resistive switching cell made from oxide crystal nanowires is thus proving to be the ideal candidate for use in building bioinspired 'neuromorphic' processors.

Anti-cancer Drugs in Yeast Produced, New Research

Nature is so complex that natural molecules used for i.e. cancer treatment still can't be produced by chemical synthesis. Today, major chemical and pharmaceutical companies harvest large amounts of rare plants and seeds in order to extract valuable substances.

Microscopic 'Sunflowers' for Better Solar Panels

Scientists have harnessed magnetic fields to control the molecular structure of liquid crystal elastomers and create microscopic three-dimensional polymer shapes that can be programmed to move in any direction in three-dimensional space in response to multiple types of stimuli, including light and heat. The applications of this technology include message encryption, responsive solar panels, and smart buildings.
