Review shows minimal, high-quality evidence dietary supplements lead to weight loss

Although Americans spend billions on them, published research shows a lack of strong evidence that dietary supplements and alternative therapies help adults lose weight, according to a new study published in Obesity.

Salton Sea aerosol exposure triggers unique and mysterious pulmonary response

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.

Geckos might lose their tails, but not their dinner

A new UC Riverside study finds geckos are fierce hunters whether or not their tails are attached to their bodies.

Nightside radio could help reveal exoplanet details

We can't detect them yet, but radio signals from distant solar systems could provide valuable information about the characteristics of their planets.

Study reveals agriculture-related injuries more numerous than previously known

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.

Study provides MIS-C treatment guidance

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 Control and Prevention (CDC). The results were published online in the New England Journal of Medicine.

Songbirds and humans share some common speech patterns

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.

Attention anti-vaccinators: Skin reactions to mRNA COVID-19 vaccines are no cause for alarm

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.

Sound-induced electric fields control the tiniest particles

Engineers at Duke University have devised a system for manipulating particles approaching the miniscule 2.5 nanometer diameter of DNA using sound-induced electric fields. 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.

Methodology from GWAS accurately flags more deadly SARS-CoV-2 variant

Using genome-wide association studies (GWAS) methodology to analyze whole-genome sequencing data of SARS-CoV-2 mutations and COVID-19 mortality data can identify highly pathogenic variants of the virus that should be flagged for containment, according to Harvard T.H. Chan School of Public Health and MIT researchers.

Political variables carried more weight than healthcare in government response to COVID-19

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.

Research may help identify more dangerous strains of the virus that causes COVID-19

Viral mutations during the COVID-19 pandemic could cause the SARS-CoV-2 virus to become more dangerous. A new study published in Genetic Epidemiology has examined the genetic code of SARS-CoV-2 viruses that have infected patients, looking for links between different mutations and patient deaths.

Do hormonal contraceptives impact glaucoma risk?

Women who currently use hormonal contraceptives face more than a 2-fold higher risk of developing glaucoma, according to an analysis of electronic medical records for women aged 15-45 years from 2008 to 2018. The British Journal of Clinical Pharmacology analysis included 2,366 women who developed glaucoma and 9,464 controls.

Insights on the link between chronic stress and Alzheimer's disease

Chronic psychosocial stress—which involves a pathway called the hypothalamic-pituitary-adrenal axis (HPA axis)—may contribute to the development of Alzheimer's disease. A new review published in Biological Reviews describes how environmental and genetic factors can impact individuals' HPA axis, and ultimately their risk of Alzheimer's disease.

Can genetic tests predict children's risk of developing scoliosis?

In a study published in the Journal of Bone and Mineral Research, investigators developed and validated a genetic risk score for predicting the onset and severity of the most common type of scoliosis in adolescents—called adolescent idiopathic scoliosis (AIS). AIS causes spinal deformities in as many as 3% of youth, and because its heritability is high, genetic data could help improve detection.

MicroRNAs may play a role in COVID-19

New research published in the Journal of Cellular and Molecular Medicine indicates that SARS-CoV-2, the virus that causes COVID-19, produces microRNAs that can have impacts on infected cells. MicroRNAs are genetic molecules that prevent the production of particular proteins by binding to and destroying messenger RNAs that code for those proteins.

Schools should strive to improve students' food literacy

An article published in the Journal of School Health stresses that food literacy—understanding the impact of food choices on our health, environment, and economy—should be a priority for K-12 schools during the COVID-19 pandemic and beyond.

Study on fiscal policy advocates for making hay while the sun shines

A study published in Economic Inquiry that examined data from 133 countries from 1950-2014 found that a reduction in fiscal space—with fiscal space being the ability of governments to provide resources without undermining fiscal sustainability—in high income countries following the global financial crisis in 2007-2009 prevented these economies from adopting countercyclical fiscal policies. A countercyclical fiscal policy stance aims to smooth out business cycle fluctuations, through greater spending during recessions and lower spending during booms.

Foreign-born status, but not acquired US citizenship, protects many immigrants from criminal victimization

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.

Parental monitoring and consistency in adolescence can reduce young Black men's likelihood of criminal behavior

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.
