If you listen to songbirds, you will recognize repeated melodies or phrases. Each phrase is made up of distinct sounds, strung together. A study from researchers at McGill University has found that the song phrases of many songbird species follow patterns that are similar to those used in human speech. At least in some respects. The songbirds the researchers studied, like humans---no matter what language they speak---tend to use shorter elements (whether these are words or sounds) when they are putting together longer phrases. Linguists speculate that this pattern, known as Menzerath's Law, may make communication more efficient by making things easier to understand or say. But the McGill team suggest ...

New York, NY--June 22, 2021--Because corporations and governments rely on computers and the internet to run everything from the electric grid, healthcare, and water systems, computer security is extremely important to all of us. It is increasingly being breached: Numerous security hacks just this past month include the Colonial Pipeline security breach and the JBS Foods ransomware attacks where hackers took over the organization's computer systems and demanded payment to unlock and release it back to the owners. The White House is strongly urging companies to take ransomware threats seriously and update their systems to protect themselves. Yet these attacks continue to threaten all of us on an almost daily basis. Columbia Engineering researchers ...

RIVERSIDE, Calif. -- Communities surrounding the Salton Sea, the inland body of water straddling California's Riverside and Imperial counties, show high rates of asthma due, possibly, to high aerosol dust levels resulting from the sea shrinking over time. Scientists suspect, however, the Salton Sea plays an additional role in pulmonary health. A University of California, Riverside study performed on mice has found Salton Sea aerosol turns on nonallergic inflammation genes and may also promote lung inflammation. For comparison, aerosolized fungal allergen (Alternaria) -- a common household fungal allergen -- produces an allergic inflammation in the lungs of mice. "Our ...

Dubbed "acoustoelectronic nanotweezers," the approach provides a label-free, dynamically controllable method of moving and trapping nanoparticles over a large area. The technology holds promise for applications in the fields ranging from condensed matter physics to biomedicine. The research appears online on June 22 in Nature Communications. Precisely controlling nanoparticles is a crucial ...

Until recently, data on criminal victimization did not include information on the status--immigrant or citizen--of respondents. In a recent study, researchers used new data that include respondents' status to explore the association between citizenship status and risk of victimization. They found that for many, a person's foreign-born status, but not their acquired U.S. citizenship, protects against criminal victimization. The study, by researchers at the University of Maryland (UMD) at College Park and the Pennsylvania State University (PSU), is forthcoming in Criminology, a publication of the American Society of Criminology. "Understanding how patterns of victimization vary ...

New Orleans, LA - An analysis conducted by a group of investigators including Tamara Bradford, MD, Associate Professor of Pediatrics at LSU Health New Orleans School of Medicine, found that children and adolescents with Multisystem inflammatory syndrome in children (MIS-C) initially treated with intravenous immune globulin (IVIG) plus glucocorticoids had a lower risk of new or persistent cardiovascular dysfunction than IVIG alone. The research was part of the Overcoming COVID-19 Study, a nationwide collaboration of physicians at pediatric hospitals and the Centers for Disease ...

HOUSTON - (June 22, 2021) - We can't detect them yet, but radio signals from distant solar systems could provide valuable information about the characteristics of their planets. A paper by Rice University scientists describes a way to better determine which exoplanets are most likely to produce detectable signals based on magnetosphere activity on exoplanets' previously discounted nightsides. The study by Rice alumnus Anthony Sciola, who earned his Ph.D. this spring and was mentored by co-author and space plasma physicist Frank Toffoletto, shows that while radio emissions from the daysides of exoplanets appear to max out during high solar activity, those that emerge from the nightside are likely to add significantly to the signal. This interests the exoplanet ...

New research examined the effect of different parenting styles during adolescence on crime among African American men. The study found that parenting styles characterized by little behavioral control placed youth at significant risk for adult crime, even though some of those styles included high levels of nurturance. In contrast, youth whose parents monitored them, were consistent in their parenting, and had high levels of behavioral control were at lowest risk for adult crime. The study, by researchers at the University of Georgia and Mississippi State University, is forthcoming in Criminology, a publication of the American Society of Criminology. "We examined parenting styles rather than parenting ...

MORGANTOWN, W.Va. - Sunday church service in Amish country is more than just belting out hymns, reading Bible passages and returning home an hour later to catch a football game or nap. It's an all-day affair: A host family welcomes church members - between 20 to 40 families - into their home to worship and have fellowship with one another from morning to night. Church is a biweekly activity; each gathering takes place in a member's home and is a key ritual in the Amish community which values in-person communication. New research from West Virginia University sociologists suggests this face-to-face interaction, coupled with a distrust ...

A new study by Penn State researchers, who looked at emergency room admissions across the U.S. over a recent five-year period in a novel way, suggests that the agriculture industry is even more dangerous than previously believed. The research revealed that from Jan. 1, 2015, to Dec. 31, 2019, more than 60,000 people were treated in emergency departments for nonfatal, agricultural-related injuries. Significantly, nearly a third of those injured were youths, according to study author Judd Michael, Nationwide Insurance Professor of Agricultural Safety and Health and professor of agricultural and biological engineering, College of Agricultural Sciences. "This study revealed the true magnitude of the agricultural-related injury problem," he said. "We were slightly ...

Interstate highway systems and networks of dense urban roads typically receive top billing on maps, in infrastructure legislation and in travelers' daily commuting routes. However, more than 80% of all US roads are considered low-volume roads - defined as those that carry fewer than 1000 vehicles per day. According to a new report published by the Ecological Society of America, "The Ecology of Rural Roads: Effects, Management and Research," this less-traveled road network can have an outsized impact on surrounding ecosystems, altering the local hydrology, affecting wildlife populations and shuttling ...

WASHINGTON--More than half of the structures in the contiguous United States are exposed to potentially devastating natural hazards--such as floods, tornadoes and wildfires--according to a new study in the AGU journal Earth's Future, which publishes interdisciplinary research on the past, present and future of our planet and its inhabitants. Increasing temperatures and environmental changes contribute to this trend, and the research also shines the light on another culprit: the way humans develop open land, towns and cities. "We know that climate ...

Large thunderstorms in the Southern Great Plains of the U.S. are some of the strongest on Earth. In recent years, these storms have increased in frequency and intensity, and new research shows that these shifts are linked to climate variability. Co-authored by Christopher Maupin, Courtney Schumacher and Brendan Roark, all scientists in Texas A&M University's College of Geosciences, along with other researchers, the findings were recently published in END ...

Managing type 2 diabetes typically involves losing weight, exercise and medication, but new research by Dr. Makoto Fukuda and colleagues at Baylor College of Medicine and other institutions suggests that there may be other ways to control the condition through the brain. The researchers have discovered a mechanism in a small area of the brain that regulates whole-body glucose balance without affecting body weight, which suggests the possibility that modulating the mechanism might help keep blood sugar levels in a healthy range. "A growing body of evidence strongly suggests that the brain is a promising yet unrealized ...

Philadelphia, June 22, 2021 - Vivid photos of the red "COVID arm" rash and reports of facial swelling in patients who have received dermatological fillers after Pfizer-BioNTech or Moderna vaccination for COVID-19 may increase patients' concerns about mRNA vaccine side effects and contribute to vaccine hesitancy. A comprehensive review in Clinics in Dermatology, conducted by University of Connecticut School of Medicine researchers and published by Elsevier, confirms that almost all cutaneous reactions are largely self-limited and should not discourage getting the vaccine. The authors reviewed ...

Poll of 1,161 Ontario students shows attitudes toward cannabis differ from alcohol, creating potentially risky and dangerous driving behaviour Ontario students are more likely to get behind the wheel of a vehicle after smoking cannabis than drinking alcohol, a new study from researchers at the University of Ottawa's Faculty of Medicine has revealed. The study, published in Preventive Medicine, found 10 percent of licensed Ontario high school students reported driving within an hour of cannabis use. Driving after drinking alcohol was much less prevalent, with 3.5 percent of students doing so. The study, led by master's student Nathan Cantor, found that students who favour cannabis ...

BINGHAMTON, N.Y. -- Political institutions such as the timing of elections and presidentialism had a larger influence on COVID-19 strategies than the institutions organizing national healthcare, according to a research team led by a professor at Binghamton University, State University of New York. Olga Shvetsova, a political scientist at Binghamton University, and fellow researchers explored policy strategies on public health by the federal incumbents worldwide. Specifically, they looked at whether national incumbents led the charge as the pandemic unfolded ...

Dietary protein is needed to supply essential amino acids for the synthesis of the structural and functional components of living cells. Thus, food protein quantity and quality are both essential for good health. The 2020-2025 Dietary Guidelines for Americans (DGAs) published an "ounce equivalents" recommendation to help consumers meet protein requirements with a variety of protein food sources. For example, the DGAs present a variety of "ounce equivalents" in the protein food groups stating that 1 ounce of meat is equivalent to 1 cooked egg, ¼ cup of red kidney beans, 1 tablespoon of peanut butter, 2 ounces of tofu, ...

Irvine, CA - June 22, 2021 - A new University of California, Irvine-led study reveals albumin (Alb), among the most abundant proteins in the body, activates a proton channel (hHv1), also widespread in the body, giving sperm the ability to penetrate and fertilize an egg, and allowing white blood cells to secrete large amounts of inflammatory mediators to fight infection. The study titled, "Direct activation of the proton channel by albumin leads to human sperm capacitation and sustained release of inflammatory mediators by neutrophils," was published today in Nature Communications. Researchers examined the physiological ...

Machine learning algorithms do a lot for us every day--send unwanted email to our spam folder, warn us if our car is about to back into something, and give us recommendations on what TV show to watch next. Now, we are increasingly using these same algorithms to make environmental predictions for us. A team of researchers from the University of Minnesota, University of Pittsburgh, and U.S. Geological Survey recently published a END ...
