What The Study Did: Changes in emergency department visits and hospitalizations as the COVID-19 pandemic intensified in the U.S. are examined in this observational study that included 24 emergency departments in five health care systems in Colorado, Connecticut, Massachusetts, New York and North Carolina.
Authors: Edward R. Melnick, M.D., M.H.S., of the Yale University School of Medicine in New Haven, Connecticut, is the corresponding author.
A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience. The findings effectively throw cold water on the dominant "warm and wet ancient Mars" hypothesis, which postulates that rivers, rainfall and oceans once existed on the red planet.
Washington, DC-- New work led by Carnegie's Peng Ni and Anat Shahar uncovers new details about our Solar System's oldest planetary objects, which broke apart in long-ago collisions to form iron-rich meteorites. Their findings reveal that the distinct chemical signatures of these meteorites can be explained by the process of core crystallization in their parent bodies, deepening our understanding of the geochemistry occurring in the Solar System's youth. They are published by Nature Geoscience.
Advancing the understanding of synovial sarcoma, a highly aggressive and rare cancer of young people, scientists at Dana-Farber Cancer Institute have discovered how an abnormal protein misdirects and disrupts the control of gene expression in cells, causing the aberrant activation of normally repressed genes that contribute to the malignant growth of sarcoma tumors.
ROCHESTER, Minn. -- As COVID-19 swept into the U.S., hospitals across the country have reported that their emergency departments are emptying out. In a new study published Monday, Aug. 3, in JAMA Internal Medicine, a team of researchers from multiple institutions provides insights into this phenomenon.
What The Study Did: International professional societies developed recommendations for minimum clinical standards to determine brain death/death by neurologic criteria in adults and children to improve the consistency of these criteria within and among countries.
Authors: Gene Sung, M.D., M.P.H., of the University of Southern California in Los Angeles, is the corresponding author.

Despite decades of positive messaging to encourage women and girls to pursue education tracks and careers in STEM, women continue to fall far below their male counterparts in these fields. A new study at Carnegie Mellon University examined 25 languages to explore the gender stereotypes in language that undermine efforts to support equality across STEM career paths. The results are available in the August 3rd issue of Nature Human Behavior.
A team of researchers from Japan has demonstrated a light-based reaction that yields high numbers of the base chemical component required to produce bioactive compounds used in common industry products.
They published their results on June 11 in Organic Letters.
"We developed a redox potential-controlled and cost-effective method to synthesize multisubstituted cyclobutanes, which are present in the core structure of various products and bioactive components," said paper author Yujiro Hoshino, a research associate at Yokohama National University.
Researchers have demonstrated the use of a ground-breaking circuit design that could transform manufacturing processes for wearable technology.
Silicon-based electronics have aggressively become smaller and more efficient over a short period of time, leading to major advances in devices such as mobile phones. However, large-area electronics, such as display screens, have not seen similar advances because they rely on a device, thin-film transistor (TFT), which has serious limitations.
African-Americans have up to three times the risk of dying from strokes as people of European descent, yet there has been little investigation of if and how genetic variants contribute to their elevated stroke risk. Until now.
In this age of racial reckoning, new research findings indicate that racial discrimination is so painful that it is linked to the ability to die by suicide, a presumed prerequisite for being able to take one's own life. However, the ability to emotionally and psychologically reframe a transgression can mitigate its harmful effects.
Philadelphia, August 3, 2020--Whether children have ongoing sleep problems from birth through childhood or do not develop sleep problems until they begin school, a new study by researchers at Children's Hospital of Philadelphia (CHOP) has found that sleep disturbances at any age are associated with diminished well-being by the time the children are 10 or 11 years old.
Chlamydia are bacteria that cause venereal diseases. In humans, they can only survive if they enter the cells. This is the only place where they find the necessary metabolites for their reproduction. And this happens in a relatively simple way: the bacteria create a small bubble in the cell and divide in it over several generations.
Considered the "guardian of the genome," TP53 is the most commonly mutated gene in cancer. TP53's normal function is to detect DNA damage and prevent cells from passing this damage on to daughter cells. When TP53 is mutated, the protein made from this gene, called p53, can no longer perform this protective function, and the result can be cancer. Across many cancer types, mutations in TP53are associated with worse outcomes, like disease recurrence and shorter survival.
AMES, Iowa -- New research suggests that demolishing abandoned houses may lead nearby property owners to better maintain their homes.
This study, by Daniel Kuhlmann, assistant professor of community and regional planning at Iowa State University, was published recently in the peer-reviewed Journal of Planning Education and Research. He examined whether the demolition of dilapidated and abandoned housing affects the maintenance decisions of nearby homeowners.
