COVID-19 made unequal access to food worse, study suggests
When COVID-19 hit, affluent Columbus residents responded by taking significantly fewer trips to large grocery and big-box stores, apparently ordering more online and stocking up when they did go out to shop.With fewer options available to them, low-income people had to double down on what they had always done: regular trips to the local dollar stores and small groceries to get their family's food.

Bonding's next top model -- Projecting bond properties with machine learning
Researchers from The University of Tokyo Institute of Industrial Science have developed a machine learning-based model to predict the characteristics of bonded systems. Using the density of states of the individual component reactants, they have achieved accurate predictions of the binding energy, bond length, number of covalent electrons, and Fermi energy. The broadly applicable model is expected to make a significant contribution to the development of materials such as catalysts and nanowires.

Why identical mutations cause different types of cancer
Why do alterations of certain genes cause cancer only in specific organs of the human body? Scientists at the German Cancer Consortium (DKTK), the Technical University of Munich (TUM), and the University Medical Center Göttingen have now demonstrated that cells originating from different organs are differentially susceptible to activating mutations in cancer drivers.

New alpine moth solves a 180-year-old mystery
Butterflies and moths are among the most diverse animal groups. Scientists have found as many as 5,000 species from the Alps alone. Having been a place of intensive research for 250 years, it is considered a sensation if a new species is discovered from the mountain range these days. This was the case when a Swiss-Austrian team of researchers described a new species of alpine moth in the peer-reviewed journal Alpine Entomology.

Discrimination and safety concerns barriers to accessing healthy food for food-insecure young adults
University of Minnesota School of Public Health researchers recently completed a study to determine how food-insecure young (emerging) adults (18-29 years of age) adapted their eating and child feeding behaviors during the COVID-19 pandemic. The researchers also sought to identify barriers to food access and opportunities to improve local access to resources for emerging adults. Their study results are published in the Journal of the Academy of Nutrition and Dietetics.

Preparing for the next pandemic: Harmonize vaccinations in Canada
To prepare for the next pandemic and provide a coordinated approach to vaccination across the country, Canada should create Canadian Immunization Services based on the Canadian Blood Services model, authors propose in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.210670.

Three key habitat-building corals face worrying future due to climate crisis
The climate crisis will lead to changes in distribution and habitat loss of stony corals in the tropical Atlantic, shows a new study published by the open access publisher Frontiers. The loss of such coral species could have devastating consequences for the marine ecosystems they inhabit. The results of the study highlight an urgent need for coral reef management in the Atlantic.

Words matter: Language can reduce mental health and addiction stigma, NIH leaders say
In a perspective published in Neuropsychopharmacology, leaders from the National Institutes of Health address how using appropriate language to describe mental illness and addiction can help to reduce stigma and improve how people with these conditions are treated in health care settings and throughout society. The authors define stigma as negative attitudes toward people that are based on certain distinguishing characteristics.

A bug's life: Millimeter-tall mountains on neutron stars
New models of neutron stars show that their tallest mountains may be only fractions of millimetres high, due to the huge gravity on the ultra-dense objects. The research is presented today at the National Astronomy Meeting 2021.
