Slow motion makes soccer referees more likely to give a red card
Video assistant refereeing in soccer has to be used with caution. Researchers have shown that refs are more likely to give red when they see a foul committed in slow motion, even when a yellow card is more justifiable. This is because fouls viewed in slow motion appear to be more serious.

Researchers discover novel colistin resistance gene mcr-3 in Escherichia coli
A new mobile colistin resistance gene, mcr-3, has been discovered in E. coli of pig origin. The novel mcr-3 gene was discovered when a colistin-resistant Escherichia coli isolate tested negative for both mcr-1 and mcr-2. This novel mobile colistin resistance gene may already be widely disseminated. Screening for the mcr-3 gene should be urgently included in the surveillance of colistin-resistant Gram-negative pathogens from animals, humans, and the environment.

Transcranial stimulation and/or physical therapy improves walking speed in Parkinson's disease
Noninvasive brain stimulation and physical therapy -- alone or in combination -- improve some measures of walking ability in patients with Parkinson's disease (PD), concludes a clinical trial.

Key player in heart enlargement identified
The heart is a dynamic muscle that grows and shrinks in response to stressors such as exercise and disease. The secret to its malleability lies in individual cells, which get bigger or smaller depending on the heart's needs. A new study of mouse hearts reveals a previously unknown mechanism by which heart cells control their size by ramping up or stopping the production of a key factor called PABPC1.

Structures vital to virus replication illuminated
Scientists have, for the first time, imaged molecular structures vital to how a major class of viruses replicates within infected cells. The research uses pioneering cryo-electron tomography to reveal the complex viral replication process in vivid detail, opening up new avenues to potentially disrupt, dismantle or redirect viral machinery.

Pathway to 'rejuvenating' immune cells to fight cancers and infections
A new discovery of the mechanism of T cell exhaustion will lead to treatments to enhance immunotherapies against cancers and such viruses as HIV.

Yoga more risky for causing musculoskeletal pain than you might think
Yoga causes musculoskeletal pain in 10 percent of people and exacerbates 21 percent of existing injuries, research shows. The findings come from the first prospective study to investigate injuries caused from recreational participation in yoga. The injury rate is up to 10 times higher than has previously been reported.

The dust storm microbiome
The airborne dust carried in sand storms affects the health of people and ecosystems alike. New research suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms.

How many protozoa are in the water we drink?
Researchers have analyzed drinking water and detected oocysts of Cryptosporidium and cysts of Giardia, two protozoa that cause outbreaks of diarrhea in humans. The levels detected are very low and do not represent a health risk; however, according to the study, the ubiquity of these parasites and the inefficiency of conventional water treatment in reducing them may present a public health issue.
