Goal-setting and positive parent-child relationships reduce risk of youth vaping
Adolescents who set goals for their future and those with strong parental support are less likely to use e-cigarettes and other tobacco products, according to a new survey of nearly 2,500 high school students. The findings suggests that strategies to prevent youth vaping may be different from what works to dissuade youth from smoking cigarettes.

Anxiety, depression, burnout rising as college students prepare to return to campus
A new survey led by The Ohio State University's Office of the Chief Wellness Officer finds students are excited to get back to campus after a long and difficult year. But the trauma of the pandemic is still affecting their mental health. The survey found anxiety, depression and burnout are all on the rise among students, even as they find normalcy again. Those issues have also led to increases in unhealthy coping mechanisms.

New study sheds light on function of sex chromosomes in turtles
A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, but the results could help to illuminate an important evolutionary process in many species. The research centers on a process known as sex chromosome dosage compensation.

<i>Tweezers of sound</i> can pick objects up without physical contact
Tokyo, Japan - Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a small polystyrene ball from a reflective surface. Although their technique employs a method similar to laser trapping in biology, adaptable to a wider range of particle sizes and materials.

Early antiviral response in the nose may determine the course of COVID-19
How early is the course of COVID-19, mild or severe, determined? In Cell, researchers examined nasal cells sampled from patients at the time of diagnosis, looking for differences between those who developed severe disease and those who experienced a mild illness. Cells from patients who developed severe COVID-19 exhibited a more muted antiviral response. If the early stages of infection can determine disease severity, it opens a path for scientists to develop early therapeutic interventions.

New tracking system monitors danger to rainforests
Similar to the election needle and the stock market index, scientists have developed a new tracking system to detect danger to rainforests around the world. The data to build the index was culled from advanced satellite measurements of climate and vegetation of each tropical region on Earth.

American Society for Colposcopy and Cervical Pathology discusses updated American Cancer Society guidelines on cervical cancer screening
Last year, the American Cancer Society (ACS) issued an updated set of guidelines for cervical cancer screening - emphasizing the shift toward screening with primary human papillomavirus (HPV) testing. While the ACS recommendation accounts for a transition period to implement primary HPV screening, additional factors should be considered to operationalize these guidelines, according to a special white paper in the July issue of the Journal of Lower Genital Tract Disease (JLGTD), official journal of ASCCP. The journal is published in the Lippincott portfolio by Wolters Kluwer.

Policing the digital divide: How racial bias can limit Internet access for people of color
A new study from the Annenberg School for Communication at the University of Pennsylvania investigated the ways that institutions control who has access to Wi-Fi. The findings indicate that powerful institutions and privileged people use quality-of-life policing -- the report and/or arrest of individuals engaged in nonviolent offenses such as loitering, noise violations, and public intoxication -- to keep those with less privilege, including people of color, from accessing resources like the internet.

Cascaded metasurfaces for dynamic control of THz wavefronts
As reported in Advanced Photonics, researchers from Shanghai University and Fudan University developed a general framework and metadevices for achieving dynamic control of THz wavefronts. Instead of locally controlling the individual meta-atoms in a THz metasurface (e.g., via PIN diode, varactor, etc.), they vary the polarization of a light beam with rotating multilayer cascaded metasurfaces.
