Toronto, ON - A new national study found that transgender preteens, 12 and13 years old, reported 13 hours of daily recreational screen time, which was 4.5 hours more than their cisgender peers. Data were collected from 2019 to 2021, overlapping with the COVID-19 pandemic, and the study was published in Annals of Epidemiology. “Transgender adolescents are more likely to experience school-based bullying and exclusion from peer groups due to their gender identity, leading them to spend less time in traditional school activities and more time on screens,” says lead author, Jason Nagata, MD, associate professor of pediatrics at the University of California, San Francisco. ...

For release: May 13, 2024 Ithaca, NY—The Giant Hummingbird of western South America is not one species but two, according to an international group of researchers. The northern population stays in the high Andes year-round while the southern population migrates from sea level up to 14,000 feet for the nonbreeding months. The two species appear identical. But looks deceive—their genomes and behaviors tell a different story. The paper announcing the find was published this week in the journal Proceedings of the National Academy of Sciences.   “These ...

In the weeks before and after the 2020 presidential election, researchers ran a number of tests to try to understand how much Facebook and its corporate cousin, Instagram, may be contributing to the nation's political divide. One of those experiments — led by Matthew Gentzkow and Hunt Allcott, economics professors at Stanford University — centered on more than 35,000 Facebook and Instagram users who were paid to stay off the platforms in the run-up to Election Day. There’s a lot that researchers could glean from the social media hiatus, including whether people’s political attitudes shifted and in what ways. If views changed dramatically, that ...

Until now, researchers and clinicians have lacked diagnostic ...

A way to curb nagging insects has been flying under our radar—an enzyme from fruit fly testes. The compound could control bugs that carry disease and harm crops by stunting their ability to procreate, Johns Hopkins University researchers found. “We have a toe in the door to control fruit fly populations with this enzyme,” said Steven Rokita, a professor of chemistry at Johns Hopkins who led the research. “It could offer a good way to control fertility of all kinds of biological and agricultural pests, starting with mosquito populations.” The findings are set to publish ...

1. A NIMS research team has demonstrated for the first time ever that a simple stack of thermoelectric and magnetic material layers can exhibit a substantially larger transverse thermoelectric effect—energy conversion between electric and heat currents that flow orthogonally to each other within it—than existing magnetic materials capable of exhibiting the anomalous Nernst effect. This mechanism may be used to develop new types of thermoelectric devices useful in energy harvesting and heat flux sensing. 2. Seebeck effect-based ...

Suddenly they appear and - like the SARS-CoV-2 coronavirus - can trigger major epidemics: Viruses that nobody had on their radar. They are not really new, but they have changed genetically. In particular, the exchange of genetic material between different virus species can lead to the sudden emergence of threatening pathogens with significantly altered characteristics. This is suggested by current genetic analyses carried out by an international team of researchers. Virologists from the German Cancer Research Center (DKFZ) were in charge of the large-scale study. “Using a new computer-assisted analysis method, we discovered 40 previously ...
