WASHINGTON (March 31, 2021)-- New research published today in the journal Environmental Health Perspectives from Environmental Defense Fund and the George Washington University shows air pollution takes an enormous toll on health in the San Francisco Bay Area, and the impacts vary dramatically within neighborhoods. The magnitude of the health burden from pollution demonstrates the need for urgent action to cut air pollution and protect health, particularly in areas facing the highest impacts.

Increased consumption of flavanols - a group of molecules occurring naturally in fruit and vegetables - could protect people from mental stress-induced cardiovascular events such as stroke, heart disease and thrombosis, according to new research.

Researchers have discovered that blood vessels were able to function better during mental stress when people were given a cocoa drink containing high levels of flavanols than when drinking a non-flavanol enriched drink.

In Brazil, researchers are puzzling over socioeconomic and environmental indicators that do not add up. They are concerned with what they call the São Paulo Macrometropolitan Area, a mega-region comprising five metropolitan areas in the state of São Paulo with a total of 180 municipalities, some of which provide ecosystem services while others receive them. The problem is that the former, which provide the others with water, food and power generation inputs, suffer from steep inequities in terms of defective human development and lack of social inclusion.

In 1890, psychologist William James described attention as the spotlight we shine not only on the world around us, but also on the contents of our minds. Most cognitive scientists since then have drawn a sharp distinction between what James termed "sensorial attention" and "intellectual attention," now usually called "attention" and "working memory," but James saw them as two varieties of the same mental process.

A team of University of Colorado School of Medicine researchers recently published a paper offering new insight into the role that oxygen deprivation, or hypoxia, plays in cancer development. CU Cancer Center member Joaquin Espinosa, PhD, is the senior researcher on the paper, which he hopes will help lead to more targeted treatments for cancer. 

In a longitudinal study published earlier this month in the Journal of the American Dental Association, researchers analyzed untreated decay in a cohort of nearly 7,000 children enrolled in the ForsythKids preventive dentistry program. Over the course of six years, the percentage of children with untreated cavities in the program decreased from 39 to 19 percent, suggesting that school-based prevention programs are effective in combating childhood dental disease.

The kangaskhan, Australia's only species of endemic Pokemon in Pokemon Go, is commonly poached within its natural habitat by Pokemon trainers for use in fighting contests

Researchers used several species distribution modeling algorithms to predict how climate change, on top of the already existing human-induced pressures, would impact the distribution of the kangaskhan in the future

Oak Brook, IL - The April edition of SLAS Discovery is a special issue on advances in protein degradation curated by guest editors M. Paola Castaldi, Ph.D., and Stewart L. Fisher, Ph.D.

WASHINGTON--A vast global ocean may have covered early Earth during the early Archean eon, 4 to 3.2 billion years ago, a side effect of having a hotter mantle than today, according to new research.

The new findings challenge earlier assumptions that the size of the Earth's global ocean has remained constant over time and offer clues to how its size may have changed throughout geologic time, according to the study's authors.

CORVALLIS, Ore. - Oregon State University researchers broadcast marbled murrelet calls in mature forests and found that the threatened seabirds' choice of breeding locations is strongly influenced by whether they hear other murrelets in the area.

The research by scientists in the OSU College of Forestry and College of Agricultural Sciences is important because the elusive seabird's populations are in decline and recovery may be hindered by there being too few birds around to provide information to each other about where to nest.

COLUMBUS, Ohio - Bangladesh's floating gardens, built to grow food during flood seasons, could offer a sustainable solution for parts of the world prone to flooding because of climate change, a new study has found.

The study, published recently in the Journal of Agriculture, Food and Environment, suggests that floating gardens might not only help reduce food insecurity, but could also provide income for rural households in flood-prone parts of Bangladesh.

PULLMAN, Wash. -- Nature's strongest material now has some stiff competition. For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than the common cubic diamonds found in nature and often used in jewelry.

Named for their six-sided crystal structure, hexagonal diamonds have been found at some meteorite impact sites, and others have been made briefly in labs, but these were either too small or had too short of an existence to be measured.

Materials such as gallium arsenide are extremely important for the production of electronic devices. As supplies of it are limited, or they can present health and environmental hazards, specialists are looking for alternative materials. So-called conjugated polymers are candidates. These organic macromolecules have semi-conductor properties, i.e. they can conduct electricity under certain conditions. One possible way of producing them in the desired two-dimensional - i.e. extremely flat - form is presented by surface chemistry, a field of research established in 2007.

A new study by Simon Fraser University's Faculty of Health Sciences researchers - published today in the American Journal of Epidemiology - found correlations between increased expressions of autistic-like behaviours in pre-school aged children to gestational exposure to select environmental toxicants, including metals, pesticides, polychlorinated biphenyls (PCBs), phthalates, and bisphenol-A (BPA).

Heavy caseloads, job stress and biases can strain relations between parole and probation officers and their clients, upping offenders' likelihood of landing back behind bars.

On a more hopeful note, a new University of California, Berkeley, study suggests that nonjudgmental empathy training helps court-appointed supervision officers feel more emotionally connected to their clients and, arguably, better able to deter them from criminal backsliding.
