WASHINGTON -- Although quantum technology has proven valuable for highly precise timekeeping, making these technologies practical for use in a variety of environments is still a key challenge. In an important step toward portable quantum devices, researchers have developed a new high-flux and compact cold-atom source with low power consumption that can be a key component of many quantum technologies.
The human intestine is made up of more than 40 square meters of tissue, with a multitude of folds on its internal surface that resemble valleys and mountain peaks in order to increase the absorption of nutrients. The intestine also has the unique characteristic of being in a continuous state of self-renewal. This means that approximately every 5 days all the cells of its inner walls are renewed to guarantee correct intestinal function.
LAWRENCE -- Tulsa may not be the first town one thinks of when talking about jazz, and flood management may not be the first vocation one compares to the musical genre. But the success Tulsa displayed in going from one of the nation's most flood-prone cities to a nationally recognized model of long-term risk reduction in just two decades is analogous to the evolution of one of the most American styles of music, a University of Kansas professor points out in a new study.
All coronaviruses produce four primary structural proteins and multiple nonstructural proteins. However, the majority of antibody-based SARS-CoV-2 research has focused on the spike and nucleocapsid proteins. A study published in PLOS Biology by Anna Heffron, Irene Ong and colleagues at the University of Wisconsin-Madison, USA, suggests that immune responses may develop against other proteins produced by the SARS-CoV-2 virus.
Think about how many different pieces of technology the average household has purchased in the last decade. Phones, TVs, computers, tablets, and game consoles don't last forever, and repairing them is difficult and often as expensive as simply buying a replacement.
In recent years, many juvenile courts have adopted in-home detention with electronic monitoring tethers as an alternative to institutional incarceration. A new study examined whether this approach reduces recidivism among girls involved in the juvenile justice system. The study found that tethers failed to reduce reoffending among the girls; in fact, they may be harmful because in-home detention limits girls' access to treatment programs.
HOUSTON - (June 21, 2021) - Rice University bioengineers collaborated on a six-year study that systematically analyzed how the surface architecture of breast implants influences the development of adverse effects, including an unusual type of lymphoma.
Every year, about 400,000 people receive silicone breast implants in the United States. According to FDA data, most of those implants need to be replaced within 10 years due to the buildup of scar tissue and other complications.
New York (June 21, 2021)--The American Geriatrics Society (AGS) has published an updated version of the AGS Minimum Geriatrics Competencies for Graduating Medical Students, which were created to ensure that medical school graduates across the U.S. are prepared to provide high-quality care for us all as we age.
WACO, Texas (June 21, 2021) - A new analysis of Venus' surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice. Published in the PNAS (Proceedings of the National Academy of Sciences), the study -- which includes contributions by Baylor University planetary physicist Peter James, Ph.D. -- found that the movement of these blocks could indicate that Venus is still geologically active and give scientists insight into both exoplanet tectonics and the earliest tectonic activity on Earth.
Women's electoral candidacies skyrocketed nationwide in the wake of the 2016 presidential election, which many saw as good news for democracy. But behavioral scholars have long maintained that women are more risk-averse than men, and thus are not as likely to sustain a prolonged political career -- involving election losses as well as wins -- the way men candidates traditionally have.
The idea that a small number of "bad apples" are responsible for an outsized share of complaints against police officers has gained considerable traction over the last four decades. A new study considered the extent to which police misconduct is likely to be reduced by removing police officers identified early in their careers as being at risk for misconduct.
Post-traumatic stress disorder (PTSD) and migraine often co-occur, but researchers knew relatively little about how or why this happens. A new study in Frontiers in Neuroscience is the first to investigate if the conditions have a common genetic basis. By studying identical twins, where one twin in each pair lives with PTSD or migraines and the other twin does not, the researchers found common genes that may play a role in both conditions.
Plastic is practical, cheap and incredibly popular. Every year, more than 350 million tonnes are produced worldwide. These plastics contain a huge variety of chemicals that may be released during their lifecycles - including substances that pose a significant risk to people and the environment. However, only a small proportion of the chemicals contained in plastic are publicly known or have been extensively studied.
BINGHAMTON, N.Y. -- Mental distress tends to be lower in the summer when compared to the fall, according to new research from Binghamton University, State University of New York.
"Our results suggest that summertime is associated with better diet quality, higher exercise frequency and improved mood. This is important for the post-COVID era as we are getting into the summer season," said Lina Begdache, assistant professor of health and wellness studies at Binghamton University.
X-ray photoelectron spectroscopy (XPS) is often used to determine the chemical composition of materials. It was developed in the 1960s and is accepted as a standard method in materials science. Researchers at Linköping University, Sweden, however, have shown that the method is often used erroneously.
