The American College of Chest Physicians® released a new clinical guideline, Screening for Lung Cancer: CHEST Guideline and Expert Panel Report containing 16 evidence-based recommendations.

Keeping your brain active in old age has always been a smart idea, but a new study suggests that reading, writing letters and playing card games or puzzles in later life may delay the onset of Alzheimer's dementia by up to five years. The research is published in the July 14, 2021, online issue of Neurology, the medical journal of the American Academy of Neurology.

Firefighters battling wildfires in the western United States use a variety of suppression tactics to get the flames under control. Prescribed burns, or controlled fires intentionally set to clear shrubs and forest litter before a wildfire ever ignites, can make fire suppression operations almost three times as effective in limiting wildfire severity, according to a new study by researchers from Penn State, the U.S. National Park Service and the U.S. Forest Service.

Researchers at the Max Planck Florida Institute for Neuroscience (MPFI) have discovered that the cell adhesion protein IgSF11 determines the layer-specific synaptic connectivity of a distinct class of cortical interneurons.

Researchers at The University of Texas at Austin and Texas Tech University created a novel analysis tool that seeks to protect the millions of people living on urban river deltas, while preserving the environmental and commercial viability of these landscapes.

Roadless national forests in the American West burn more often and at a slightly higher severity than national forests with roads, but the end result for the roadless forests is greater fire resilience, Oregon State University researchers say.

An international research team that includes scientists and engineers from The University of Texas at Austin has devised a new method for making urea that is more environmentally friendly than today's process and produces enough to be competitive with energy-intensive industrial methods.

T cells are components of the body's immune system. The ability of T cells to recognize diverse pathogens and mount a defense against them stems from the way proteins are spliced during their development and maturation. Now, scientists from Korea highlight the importance of a protein called NSrp70, which was previously discovered in T cell subnuclear spaces, in regulating the maturation of these cells, and has implications in T cell-mediated adaptive immunity against viral infection and cancer.

A new study from the University of Missouri found the unanticipated transitions to virtual schooling due to COVID-19 exposed the lack of digital resources among Black families in the United States, including access to Wi-Fi and technological savviness.

Having no children who completed college is negatively associated with parents' self-rated health and positively associated with depressive symptoms. Additionally, among parents with the highest propensity for having no children who complete college, the consequences on depressive symptoms are greatest.

Lab-based studies are critical to understanding ebola vaccine effectiveness due to the sporadic nature of outbreaks. This study identifies features of the antibody response responsible for survival from 139 immune- and vaccine-related parameters.* Findings will help develop vaccines that produce an antibody response profile which ensures protection and focuses on survival quality

Found in South Africa, this is the oldest evidence for this type of life: the discovery expand the frontiers of potentially habitable environments on the early Earth, as well as other planets such as Mars

A new study on the effects of Airbnb listings on Boston neighborhoods suggests that the prevalence of listings may hamper local social dynamics that prevent crime. However, tourists themselves do not appear to generate or attract higher levels of crime. Babak Heydari, Daniel T. O'Brien, and Laiyang Ke of Northeastern University in Boston, MA, USA present these findings in the open-access journal PLOS ONE on July 14, 2021.

An analysis of the tone used in pandemic-related social media posts from U.S. Congress members over an 8-month period in 2020 finds clear partisan differences, with Democrats using a slightly negative tone compared with Republicans, who appeared to use more strongly positive language in their COVID-19 messaging. Democrats were also far more likely than

New research, led by the Monterey Bay Aquarium, illustrates the disparity between the narrow origins and far-reaching impacts of greenhouse emissions responsible for disrupting the global climate system.

Facebook posts by members of the U.S. Congress reveal the depth of the partisan divide over the COVID-19 pandemic, new research shows.A study of all 12,031 Facebook posts concerning the pandemic by members of Congress between March and October 2020 showed that Democrats generally took a more negative or neutral tone on the issue, while Republicans were more likely to have a positive tone in their posts.

More doesn't necessarily mean better - including in cancer treatment. University of Pittsburgh School of Medicine and University of Wisconsin-Madison scientists report today in Science Translational Medicine that combining targeted radiopharmaceutical therapy with immunotherapy significantly boosts eradication of metastatic cancer in mice, even when the radiation is given in doses too low to destroy the cancer outright.

Newborns at higher altitudes have up to 37 percent higher mortality rates, perhaps because of lower availability of blood oxygen, vitamins and minerals.

Phone conversations contain vocal features which might help identify early Alzheimer's disease, thanks to a new machine-learning model.
