Residential coal use in China results in many premature deaths, models indicate
Coal combustion by power plants and industry pollutes the air, causing many governments to implement mitigation actions and encourage cleaner forms of energy. Now, a new study in ACS' Environmental Science & Technology indicates that in China, indoor air pollution from residential coal burning causes a disproportionate number of premature deaths from exposure to tiny, inhalable pollutants known as PM2.5.

Earthworms could help reduce antibiotic resistance genes in soil
Earthworms improve the soil by aerating it, breaking down organic matter and mineralizing nutrients. Now, researchers reporting in ACS' Environmental Science & Technology have dug up another possible role: reducing the number and relative abundance of antibiotic-resistance genes (ARGs) in soils from diverse ecosystems. These results imply that earthworms could be a natural, sustainable solution to addressing the global issue of antibiotic resistance, the researchers say.

Gold leaf could help diagnose viral infections in low-resource settings
Gold leaf -- gold metal hammered into thin sheets -- is used by artists and crafters to gild picture frames, artwork and clothing. Despite its luxurious appearance, the material is affordable and available at most craft stores. Now, researchers reporting in ACS Central Science have developed gold leaf electrodes that, in combination with a CRISPR-based assay, could sensitively detect human papillomavirus (HPV) DNA in human samples. The method also could be modified to diagnose other viral infections.

CNIO researchers discover the cause of neuronal death in a large proportion of familial ALS patients
The researchers attribute the loss of motor neurons in patients with Amyotrophic Lateral Sclerosis (ALS) to a new mechanism that blocks any cellular reaction that involves nucleic acids (DNA or RNA)Many cellular processes involving nucleic acids fail in the motor neurons of ALS patients; the mechanism discovered by the CNIO group finally explains these widespread problems that have been reported for yearsThe paper is published this week in 'The EMBO Journal'

Brand new physics of superconducting metals refuted by Lancaster physicists
Lancaster University scientists have demonstrated that other physicists' recent "discovery" of the field effect in superconductors is nothing but hot electrons after all.A team of scientists in the Lancaster Physics Department have found new and compelling evidence that the observation of the field effect in superconducting metals by another group can be explained by a simple mechanism involving the injection of the electrons, without the need for novel physics.

Ancestors may have created 'iconic' sounds as bridge to first languages
The 'missing link' that helped our ancestors to begin communicating with each other through language may have been iconic sounds, rather than charades-like gestures - giving rise to the unique human power to coin new words describing the world around us, a new study reveals.

AI learns to type on a phone like humans
To really understand how people type on touchscreens, researchers at Aalto University and the Finnish Center for Artificial Intelligence (FCAI) have created the first artificial intelligence model that predicts how people move their eyes and fingers while typing. The AI model can simulate how a human user would type any sentence on any keyboard design. It makes errors, detects and corrects them, and also predicts how people adapt to a new auto-correction system or keyboard design.

Fatigue, mood disorders associated with post-COVID-19 syndrome
Patients diagnosed with post-COVID-19 syndrome, also known as "PCS," "COVID-19 long-haul syndrome" and "Post-Acute Sequelae of SARS COV-2," experience symptoms such as mood disorders, fatigue and perceived cognitive impairment that can negatively affect returning to work and resuming normal activities, according to a Mayo Clinic study published in Mayo Clinic Proceedings.

Defining climate-smart pathways towards tree crop yield intensification
A global team of researchers recently released the results of a 'data-rich' modeling approach designed to illustrate a range of what-if scenarios for future oil palm plantation development in Indonesia. The study provides new insight into crop production strategies available to an industry facing increasing scrutiny.

Eliminating bias from healthcare AI critical to improve health equity
Artificial intelligence (AI)-driven healthcare has potential to transform medical decision-making and treatment, but AI algorithms must be thoroughly tested and continuously monitored to avoid unintended consequences to patients. In JAMA Network Open, Regenstrief Institute President Peter Embí calls for algorithmovigilance (a term he coined for scientific methods and activities relating to evaluation, monitoring, understanding and prevention of adverse effects of algorithms in healthcare) to address inherent biases in healthcare algorithms and their deployment.

How social media and AI enable companies to track brand reputations in real-time
Using artificial intelligence (AI)-based text analysis of social media can monitor the extent to which brand reputation rises and falls over time. Merging this social media monitoring with the Rust-Zeithaml-Lemon customer equity drivers can show exactly which dimensions of brand reputation are changing.

New study: Kefir package claims don't always accurately reflect composition of commercial products
In recent years there has been an increased interest in the consumption of kefir, a fermented dairy beverage, because there is some evidence that it has health benefits and its affordability. A new study by researchers from the University of Illinois and The Ohio State University, published in JDS Communications, found that 66 percent of the commercial kefir products studied overstated microorganism density and 80 percent contained bacterial species that were not included on the label, potentially misleading consumers.

Telemedicine needs to be integrated into cardiology training, experts recommend
The COVID-19 pandemic has resulted in an abrupt change in healthcare delivery, including a shift from in-person visits to telemedicine. However, a Canadian survey found that a significant proportion of cardiology trainees are uncomfortable with using telemedicine and feel that better preparation for new-tech medicine is needed. Experts draw attention to the need for a telemedicine curriculum that includes supervision to prepare trainees for the expanding role of telemedicine in cardiovascular care. Survey results are published in the Canadian Journal of Cardiology.

Most frequently asked questions in rheumatology clinics answered
May 1, 2021 - Rheumatologists in Hong Kong joined hands to develop a set of consensus statements on COVID-19 vaccination for local adult patients with autoimmune rheumatic diseases. These timey statements would serve to be a guide for rheumatologists, other specialists, family physicians, specialty nurses, and the public regarding COVID-19 vaccination for patients with rheumatic diseases.
