Leo Anderson was in the middle of a baseball game when he threw a ball he had just caught, heard a crunch in his elbow and fell to the ground. That sound was a growth plate in his elbow breaking, and it ended the now-15-year-old's season last spring.

Patients with rifampicin-resistant tuberculosis (TB) and resistance to fluoroquinolones and/or injectables who were treated with bedaquiline in an optimized individualized background regimen experienced high rates of successful treatment outcomes, according to study results published in the European Respiratory Journal.
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.
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.
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.
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.
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.
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.
New research, from scientists at Imperial College London, unravels how so-called bacterial persister cells manipulate our immune cells, potentially opening new avenues to finding ways of clearing these bacterial cells from the body, and stopping recurrence of the bacterial infection.
In Bhutan, medical errors and their causes are least studied and understood due to lack of data, inexperienced staff, inadequate skills, influences of traditional beliefs and practices. This issue was discussed at panel discussion at the pre-conference workshop of fourth International Conference on Medical and Health Sciences in Thimphu.
In a new study published in the Journal of Experimental Medicine, scientists at the University of Notre Dame have discovered that the pathogen Mycobacterium tuberculosis (MTB) releases RNA into infected cells. This RNA stimulates the production of a compound known as interferon beta that appears to support the growth of the pathogen.
