An advanced artificial intelligence technique known as deep learning can predict major adverse cardiac events more accurately than current standard imaging protocols, according to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting. Utilizing data from a registry of more than 20,000 patients, researchers developed a novel deep learning network that has the potential to provide patients with an individualized prediction of their annualized risk for adverse events.

In future, it will be increasingly important to be able to predict the yields of individual varieties of cereals such as wheat as accurately as possible in a given environment. An international research team led by the IPK Leibniz Institute has compiled, processed and analyzed extensive data sets for this purpose. Ultimately, Big Data was able to double the prediction accuracy for yield.

Scientists found that the ability to fly is embedded in birds' spinal cords. The team closely examined the neural networks of chicken and mice embryos and discovered that the genetic coding of the ephrin-B3 molecule in birds is fundamentally different than those of mammals and reptiles.

Lab animals deficient in vitamin D crave and become dependent on opioids, which is curbed when normal levels of the vitamin are restored. Human health records indicate that people with low vitamin D are more likely to use and misuse opioids. Study results suggest a potential role for vitamin D supplementation in fighting opioid addiction.

In a discovery that challenges long-held dogma in biology, researchers show that mammalian cells can convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells.

Pine Island Glacier's ice shelf lost about one-fifth of its total area between 2017 and 2020, in three dramatic collapses. Meanwhile the glacier sped up by 12%. The rest of the ice shelf, the authors say, could disappear much sooner than previous studies had suggested.

What The Study Did: Editorial team composition by gender, race, ethnicity and sexual orientation was assessed at 25 leading medical and scientific journals in this survey study.

A new study evaluates the contribution of the Fenton-like reaction to atmospheric oxidation, and improves the consistency of model-simulated and field-observed secondary organic aerosol budgets.

What The Study Did: This autopsy study examines differences in skeletal muscle and myocardial inflammation in patients who died with COVID-19 versus other diseases.

Preclinical trials of a new radiopharmaceutical to treat ovarian cancer have produced successful results, dramatically limiting tumor growth and decreasing tumor mass. Designed specifically for ovarian cancers that are resistant to traditional therapies, the new radiopharmaceutical can be produced in 25 minutes at low cost, which leads to better efficiency compared with alternative methods. This research was presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting.

What The Study Did: This survey study compared features of major depression in people with or without prior COVID-19 illness.

Researchers examined the associations between Medicare Advantage star ratings, which are created using data from all enrollees in a plan, and disparities in care for racial/ethnic minorities and enrollees with lower income and less education.

3D tumors that disintegrate within a few days thanks to the action of a well-known omega-3 (DHA, found mainly in fish) -- this is the exceptional discovery by University of Louvain researchers.Hungry for fatty acids, tumor cells in acidosis gorge themselves on DHA but are unable to store it correctly and literally poison themselves. The result? They die.

What The Study Did: Researchers compared the association between symptoms and SARS-CoV-2 RNA levels in children and adults.

What The Study Did: This study of patients hospitalized with COVID-19 examines the association of anticoagulation treatment with mortality rates.

Researchers at Washington University School of Medicine in St. Louis have identified the brain regions involved in choosing whether to find out if a bad event is about to happen.

What The Study Did: Researchers describe international hospitalization trends and key epidemiological and clinical features of children and youth with COVID-19.

What The Study Did: International medical graduates often practice as physicians in locations and specialties less preferred by U.S. medical graduates. This study reports on physician mortality from COVID-19, and on the mortality of international medical graduates in particular.

UC San Diego School of Medicine researchers discovered gene expression patterns associated with pandemic viral infections, providing a map to help define patients' immune responses, measure disease severity, predict outcomes and test therapies -- for current and future pandemics.

Four planets locked in a perfect rhythm around a nearby star are destined to be pinballed around their solar system when their sun eventually dies, according to a study led by the University of Warwick that peers into its future.
