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.

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.

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.

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.

Programs exclusively focused on petting therapy dogs improved stressed-out students' thinking and planning skills more effectively than programs that included traditional stress-management information, according to new Washington State University research.

A new study led by the Centre for Nutraceuticals in the University of Westminster shows that pink drinks can help to make you run faster and further compared to clear drinks.

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.

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.

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.

A research group from the Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), suggests that the polar vortex plays a key role in Antarctic stratospheric ozone depletion.

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) has helped Gaia achieve millimagnitude (mmag) precision in photometry, according to a study led by researchers from National Astronomical Observatories of Chinese Academy of Sciences (NAOC) and Beijing Normal University (BNU).

A 'slow-motion' earthquake lasting 32 years - the slowest ever recorded - eventually led to the catastrophic 1861 Sumatra earthquake, researchers at the Nanyang Technological University, Singapore (NTU Singapore) have found.

New research at Karolinska Institutet in Sweden suggests a link between psychosis and a genetic change that affects the brain's immune system. The study published in Molecular Psychiatry may impact the development of modern medicines for bipolar disorder or schizophrenia.

Researchers report a theoretical way of mimicking thermal objects or making objects invisible to thermal measurements. And it doesn't require a Romulan cloaking device or Harry Potter's invisibility cloak.

A new study lead by Dr Kimberley Chapelle of the American Museum of Natural History and Honorary Research Fellow at the University of the Witwatersrand suggests that growth of the dinosaur Massospondylus carinatus varied season-to-season, more like a tree than a puppy or a baby human. Massospondylus was a medium sized dinosaur, up to 500kg in body weight, that lived in the Early Jurassic. The study suggests that Massospondylus' growth directly responded to its environmental conditions.

A study across 55 hospitals in Queensland, Australia suggests that a recent state policy to introduce a minimum ratio of one nurse to four patients for day shifts has successfully improved patient care, with a 7% drop in the chance of death and readmission, and 3% reduction in length of stay for every one less patient a nurse has on their workload.

Like an airplane's black box, a woman's placenta can show if something went wrong during pregnancy. A new Northwestern Medicine study of 84 vaccinated patients and 116 control patients found the COVID-19 vaccine did not damage the placenta during pregnancy.

Researchers from the Indian Institute of Technology Bombay shed light on the origins of Mimivirus and other giant viruses, helping us better understand a group of unique biological forms that shaped life on earth. In their latest study published in Molecular Biology and Evolution, the researchers show that giant viruses may have come from a complex single-cell ancestor, keeping DNA replication machinery but shedding genes that code for other vital processes like metabolism.

Researchers at Columbia Engineering report that they have built what they say is the world's smallest single-chip system, consuming a total volume of less than 0.1 mm3. The system is as small as a dust mite and visible only under a microscope. In order to achieve this, the team used ultrasound to both power and communicate with the device wirelessly.

Pregnant women who develop severe COVID-19 infections that require hospitalization for pneumonia and other complications may not be more likely to die from these infections than non-pregnant women. In fact, they may have significantly lower death rates than their non-pregnant counterparts.
