    Back To School But Not To Screens: States Ramp Up Cellphone Bans




            Work has been easier for public high school teacher Brian Kerekes since last August, when he first experienced the impacts of a newly enacted Florida law to restrict students’ cellphone use during class. The longtime statistics instructor, who started a new school year on Monday, now spends less time circling the classroom policing students and more time educating them on how to gather and interpret data.



            Before Florida passed the ban in May 2023 — becoming the first of at least eight U.S. states to prohibit or restrict cellphone use in schools — phones proved a constant disruption in Kerekes’ classroom at Tohopekaliga High School in the central Florida city of Kissimmee.



            “Students were either using them to talk to someone in a different class or talk to someone on the other side of the room or just to zone out, get on TikTok or whatever,” Kerekes, who's been a teacher for 17 years, said in an interview.



            Fellow teachers nationwide face the same challenge, which explains why more states and districts are moving to limit or outright ban cellphones in the classroom, and even during the school day altogether.

            


            The rules will look different from state to state and district to district, but all stem from the same concerns.



            Seventy-two percent of high school teachers cite cellphones as a major distraction in the classroom, according to a fall 2023 Pew Research Center study. Educators also worry that constant access to social media can adversely impact kids’ mental health.



            U.S. Surgeon General Vivek Murthy went so far as to issue a health advisory last year, warning that enough evidence exists to show social media can be unsafe for children and teens. “We are in the middle of a national youth mental health crisis,” he said, “and I am concerned that social media is an important driver of that crisis, one that we must urgently address.”



            While social media can connect kids, make them feel less alone and offer an entertaining and creative outlet, it also exposes them to harmful content, Murthy pointed out in the advisory released by the U.S. Department of Health and Human Services. And, as educators such as Kerekes note, some students use their phones to bully fellow students online during the school day, and in the most extreme cases, to set up fights and film them.

    The hope is that cellphone bans will reduce such incidents. Kerekes said he’s hearing they have.

    How companies are embracing generative AI for employees…or not


        New York CNN - Companies are struggling to deal with the rapid rise of generative AI, with some rushing to embrace the technology as workflow tools for employees while others shun it - at least for now.

        As generative artificial intelligence - the technology that underpins ChatGPT and similar tools - seeps into seemingly every corner of the internet, large corporations are grappling with whether the increased efficiency it offers outweighs possible copyright and security risks. Some companies are enacting internal bans on generative AI tools as they work to better understand the technology, and others have already begun to introduce the trendy tech to employees in their own ways.

    Bacteria use antimicrobial agent to kill competition


        Hospitalized patients are often given antibiotics, which reduces the diversity of bacteria in their microbiomes. It also allows drug-resistant strains to gain a foothold and take over. Enterococcus faecium is a gut bacterium that can cause lethal infections if it gets into the bloodstream. Vancomycin-resistant E. faecium (VREfm), which is resistant to vancomycin and multiple other antibiotics, is a growing problem in healthcare settings. Populations of VREfm within healthcare systems are known to change over time. But the factors driving these changes aren’t well understood.

        NIH-supported researchers at the University of Pittsburgh Medical Center have been collecting and sequencing bacterial DNA from hospitalized patients through the Enhanced Detection System for Healthcare-Associated Transmission (EDS-HAT). This helps clinicians to recognize and stop potential outbreaks. As part of this effort, researchers collected more than 700 VREfm samples between 2017 and 2022. A team at the university, led by Dr. Daria Van Tyne, used data from these samples to track VREfm evolution. Their findings appeared in Nature Microbiology on March 21, 2025.

        Genome sequencing of the samples identified 42 different genetic lineages, or strains, of VREfm. Almost half of the samples were closely related to at least one other sample. This suggests a high level of transmission within the hospital. Before 2020, about a third of the samples belonged to the strain ST17. From 2020 onward, two new strains, ST80 and ST117, began to take over. By the end of 2022, these two strains made up more than 80% of all samples, while ST17 was not detected.

        The researchers found that ST80 and ST117 could kill ST17, but not vice versa. Further examination revealed that ST80 and ST117, but not ST17, produce an antimicrobial peptide (a short chain of amino acids) called bacteriocin T8. Both in laboratory cultures and the guts of mice, strains that made bacteriocin T8 outcompeted strains that didn’t.

        Next, the team analyzed more than 15,000 publicly available VREfm genomes collected worldwide between 2002 and 2022. They saw the same trend, with ST17 replaced by ST80 and ST117. This suggests that the changes observed in a single hospital reflected global trends.

    NCDs at a Glance 2025. NCDs surveillance and monitoring: Noncommunicable disease mortality and risk factor prevalence in the Americas

        Effective surveillance and monitoring of noncommunicable diseases (NCDs) and their risk factors are essential for informing evidence-based public health policies, addressing health inequities, and ensuring progress toward global and regional targets. By tracking trends in NCDs, their modifiable risk factors such as tobacco use, unhealthy diets, physical inactivity, harmful use of alcohol, and air pollution, along with biological risk factors such as overweight and obesity, high blood pressure (hypertension), and elevated blood glucose (diabetes), policymakers can identify emerging threats, target vulnerable populations, allocating resources efficiently. Reliable data also enable countries to evaluate interventions, adjust policies, and strengthen health systems to reduce the burden of NCDs. This brochure presents data on NCD and suicide mortality, along with trends by sex, in the Region of the Americas and 35 Member States of the Pan American Health Organization (PAHO) from 2000 to 2021. It also highlights progress toward the 2025 global NCD targets. While the number of NCD-related deaths in the region increased to six million in 2021, the age-standardized NCD mortality rate declined by 16.2%, reflecting the impact of population growth and aging. However, premature NCD mortality — the key indicator for the Global Action Plan for NCD Prevention and Control — declined by only 0.71% annually between 2010 and 2021, falling short of the 1.92% annual reduction required to meet the 2025 target. Among modifiable risk factors, tobacco use showed the most significant decline from 2000 to 2021, while insufficient physical activity has been on the rise. Metabolic risks, including high fasting blood glucose, overweight, and obesity, exhibited concerning upward trends during this period. Hypertension control remains suboptimal, with only 36.4% of individuals achieving adequate blood pressure levels (≤140/90 mmHg). While ambient air pollution slightly decreased between 2000 and 2019, current levels remain above WHO guideline thresholds. To achieve global and regional NCD targets and improve population health in the Americas, countries must prioritize cost-effective interventions to reduce NCD mortality and address these persistent challenges.

    Utah becomes the first state to ban fluoride in public drinking water


        Utah has become the first state to ban fluoride in public drinking water, over opposition from dentists and national health organizations who warn the move will lead to medical problems and disproportionately affect low-income communities.

        Republican Gov. Spencer Cox signed legislation late Thursday that bars cities and communities from deciding whether to add the mineral to their water systems.

        Fluoride strengthens teeth and reduces cavities by replacing minerals lost during normal wear and tear, according to the U.S. Centers for Disease Control and Prevention.

    How can neuroscience lead to treatments for nicotine addiction?
    Around a billion people still smoke, so we clearly have more to learn about effective treatments for nicotine addiction. Medications that can help include bupropion, a classical antidepressant, which mostly helps people who are depressed to stop smoking; and varenicline, which imitates nicotine in some ways but prevents nicotinic receptors from being fully activated.
    Some nicotine cessation products, such as gums and patches and inhalers, use nicotine itself in the hope that it can be delivered in small enough quantities and over a long enough period of time that nicotine receptors will only be partially chaperoned, helping to reduce upregulation while the individual works on quitting smoking.
    We still need more and better science to figure out the pharmacokinetics of nicotine: How fast does it enter the body? How long does it stay in the body? To that end, along with a team of collaborators — including Caltech professors Wei Gao (professor of medical engineering), Dennis Dougherty (George Grant Hoag Professor of Chemistry), and Stephen Mayo (Bren Professor of Biology and Chemistry), and Professor Neal Benowitz of UC San Francisco — we have been working to develop a wearable device that resembles the continuous glucose monitor used by Type 1 diabetes patients.
    We will use this monitor to measure nicotine while a person smokes or vapes or uses a nicotine pouch so that we can fully understand how an individual metabolizes nicotine and relate this knowledge to a century’s worth of work on nicotinic receptors and nicotine addiction.

    INSTRUCTION: Read the following text to answer the question.

    What happens in the brain when people smoke?
    When nicotine enters the lungs, it’s in the brain 20 seconds later. In this journey, nicotine has traveled through the cells in the lungs to the blood — and then from the blood to the brain, passing through the blood‑brain barrier. In all, nicotine passes through six membranes when it’s smoked or vaped.
    Once nicotine is in the brain, it activates the most sensitive nicotinic receptors on membranes of nerve cells, or neurons, but it also travels through the membrane to enter the neuron. Finally, it passes into the organelles of the neuron, where proteins, including the nicotinic receptor, are being made. When a person smokes, nicotine actually helps the cell to assemble more nicotinic receptors, which travel out of the endoplasmic reticulum (part of the cellular transportation system) and onto the surface of the cell. It’s as though nicotine is acting as a pharmacological “chaperone” to bring those receptors to the surface of the cell.
    We have labeled this process “inside out” pharmacology. In trying to unravel the cell biology of nicotine addiction, my lab and others study how this so‑called chaperoning or upregulating of nicotinic receptors is necessary for the early stages of nicotine dependence, ultimately underlying the brain’s addiction to nicotine. When a person stops taking nicotine, the natural acetylcholine cannot sufficiently activate the upregulated receptors. They produce craving and other symptoms of withdrawal.

    Abstract


    Rare diseases are diseases that affect fewer than 1 in 2,000 people. Due to their rarity, it can be extremely challenging for doctors to diagnose these diseases in their patients — it often takes 6 – 8 years for some patients to get a diagnosis. Even though they are uncommon, rare diseases still have a significant impact on families and communities and need greater attention. Fatal familial insomnia (FFI) is a rare disease that affects the brain and gradually reduces a person’s ability to sleep. FFI gets worse over time and causes severe complications. There is currently no cure for FFI, so more research is crucial — not only for understanding FFI but also for unlocking potential treatments for other rare diseases. Rare disease research brings hope for a better future to those living with FFI and other rare conditions.

        UNICEF reports that, for the first time, global childhood obesity has surpassed underweight rates, with one in ten school-aged children now obese, about 188 million worldwide. Meanwhile, one in five children under 19 years old globally, or 391 million, is overweight.

        Kids are considered overweight if they carry excess weight for their age, sex and height, while obesity is a more severe form that greatly increases the risk of serious health problems later in life. Between year 2000 and 2022, obesity rates among those aged 5 to 19 more than tripled from 3% to 9.4%, while underweight cases fell.

        The shift is driven by the rise of ultra-processed foods, which are replacing fruits, vegetables and proteins. Obesity hotspots are emerging worldwide, especially in low and middle-income countries still battling undernutrition, while wealthy nations like the United States, United Arab Emirates and Chile also show high rates. Pacific Island nations face the highest prevalence, with up to 40% of youth obese.

        The crisis is fueled by aggressive junk food marketing, with 75% of children exposed weekly. Obesity raises risks of diabetes, heart disease and cancer. UNICEF is calling for urgent restrictions on unhealthy food marketing and school bans, warning of severe health impacts for the next generation.

        For over 35 years, Rush University Medical Center in Chicago, in United States of America, has been helping infant patients and their families through a volunteer cuddler program.

        When families are away from the hospital’s neonatal intensive care unit (NICU), volunteers comfort infants with cuddles. Families can’t be in the hospital all the time, but the babies had needs after they left. The staff understood these needs and volunteer cuddlers helped. A lot of the volunteers are parents whose children were in the NICU before. After undergoing extensive training, they are using their experiences and skills to provide other parents a sense of relief and security.

        Studies show that interactions like holding, rocking, singing, reading and talking to the infants reduce stress and pain, and they improve their overall physical health.
