They Were Diagnosed With Autism as Adults. It Has Changed Their Lives.
In grade school, Jamie Donovan often spent recess picking bark off trees. At home, she sometimes hid in her father's truck if she needed to block out visual stimulation and sounds. She usually had trouble relating to other people, and felt like she was always saying the wrong thing. She didn't understand the reason until she was almost 47 years old—when she was diagnosed with autism spectrum disorder.

How low vitamin D at birth could predict future mental illnesses like autism
A newborn with low levels of vitamin D could be more likely to develop mental health conditions like autism, attention deficit-hyperactivity disorder (ADHD), and schizophrenia later in life, according to a Lancet study involving the University of is supposed to be the largest population-based study to date looking at vitamin D and mental disorders, published in assessed the vitamin D status of over 71,000 individuals, many of whom had been diagnosed with mental health disorders during childhood or early John McGrath from Queensland Brain Institute, who led the study in collaboration with Denmark's Aarhus University and the State Serum Institute, said that the team examined six mental disorders: major depressive disorder, bipolar disorder, schizophrenia, ADHD, autism spectrum disorder (ASD), and anorexia nervosa."We found evidence that people with lower vitamin D concentration as a baby had an increased risk of schizophrenia, ASD and ADHD,' McGrath added that their findings support the idea that vitamin D supplementation during pregnancy and early life may help reduce the risk of developing certain mental disorders later on. People with lower vitamin D concentration as a baby had an increased risk of schizophrenia. () advertisement"Vitamin D is important for a baby's brain development, and low vitamin D levels are common in pregnant women across the globe," he understand the broader impact of this research, spoke to Dr Himani Narula Khanna, a developmental behavioural paediatrician and adolescent mental health expert, who confirmed that a growing number of studies have drawn similar referred to earlier research, including a 2016 cohort study in Denmark and another in Finland, which found that babies born to mothers with low vitamin D levels had a higher risk of developing schizophrenia, ADHD, and autism symptoms in childhood or adulthood."Among these, schizophrenia and autism have shown a twofold increase in risk with low vitamin D levels. ADHD, depression and anxiety have also been linked, though the evidence is slightly more variable," she to Dr. Narula, vitamin D has a huge impact on brain development. It helps regulate neurotrophic factors, which support neuron growth and also influences the brain's dopamine and serotonin systems, which are crucial for mood and emotional regulation. 'Vitamin D also helps reduce inflammation and oxidative stress in the brain and supports the formation of neural pathways. All of these are important for healthy brain development," she what's the best way to ensure enough vitamin D during pregnancy? Dr. Narula recommends daily supplements of 600 to 2000 IU (International Units) of vitamin D3, or even up to 4000 IU under a doctor's advice.'Sunlight exposure, about 10 to 30 minutes several times a week, can also help, but this depends on skin tone, clothing and where you live,' she sources include fatty fish like salmon and sardines, egg yolks, fish liver oil, fortified dairy or plant-based milk, and certain cereals and juices. Low vitamin D levels are common in pregnant women across the globe. () However, she added, 'Vitamin D is hard to get in sufficient amounts through food alone, which is why supplements are often necessary.'Importantly, vitamin D deficiency is not the only factor that may increase the risk of mental illness.'Other contributors include genetic predisposition, maternal stress or infections during pregnancy, exposure to air pollution, poor nutrition, low birth weight, and lack of emotional stimulation in early life,' Dr. Narula to vitamin D-rich foods and supplements is also a challenge. 'In low-income countries, fortified foods may not be common, and supplements may be too expensive or unavailable,' she in wealthier countries, people with darker skin or those who avoid sun exposure due to cultural practices can be at higher Reel

AT&T still has money left allowing it to improve its 5G coverage in the U.S.
According to the tea leaf readers (AKA analysts) working for New Street Research, AT&T still has some money left in the bank after the $5.75 billion deal to buy consumer fiber firm Lumen Technologies. The deal was announced Wednesday and on Friday, New Street Research said that the aforementioned transaction isn't expected to stop the nation's third largest wireless carrier from buying more mid-band 3.45GHz spectrum for its 5G wireless service. We often pass along the story about how T-Mobile became the 5G leader in the U.S. AT&T and Verizon started building out their 5G networks using its fastest airwaves, millimeter wave (mmWave), which is in the high-band. What AT&T and Verizon failed to take into consideration was that as fast as mmWave spectrum is, it travels extremely short distances which limits the number of customers able to connect to these signals. T-Mobile's 5G layer cake which helped it take the early 4G lead in the States. | Image credit-T-Mobile Meanwhile, T-Mobile had a different idea. Using the 2.5GHz mid-band spectrum it picked up from Sprint in the $26 billion acquisition of its rival, T-Mobile proved that using mid-band was the way to build a 5G network in the U.S. Not as fast as mmWave, mid-band is still faster than low-band. While mid-band signals don't travel as far as low-band, they do travel longer distances than mmWave. T-Mobile rode its Goldilocks mid-band spectrum to become the early 5G leader in the U.S., a position it still has to this day. But the story doesn't end there. Taking notice of T-Mobile 's success using mid-band airwaves, AT&T and Verizon spent more than $68 billion to win several C-band licenses during an FCC auction. Still, AT&T has admitted that it seriously trails T-Mobile and Verizon in mid-band and is using a strategy that includes using C-band spectrum (3.7GHz-4.2GHz) and 3.45GHz mi-band spectrum to catch up to its rivals. - AT&T New Street says that AT&T has the financial wherewithal to buy more spectrum. A new report from Light Reading says that AT&T is already kicking the tires on the purchase of $1.2 billion of 3.45GHz spectrum from UScellular and SoniqWave. That would leave AT&T with $3 billion available for additional spectrum purchases according to AT&T . New Street's analysis puts that figure at $7 billion. If New Street's forecast of AT&T 's cash is correct, the $7 billion would give AT&T enough juice to buy the 3.45GHz spectrum that T-Mobile sold Columbia Capital last September, and some AWS-3 licenses that AT&T is expected to buy. However, it should be pointed out that if AT&T plans on buying Columbia Capital's 3.45GHz holdings, it will have to sell part of Lumen's fiber business to an equity partner. Such a move was already baked into the AT&T -Lumen deal. Back in March, AT&T requested a waiver from the FCC allowing it to exceed the regulatory agency's limit of 40MHz of 3.45GHz spectrum that a carrier can control. The 40MHz limit expires next January 4th. But because its acquisition of 3.45 GHz spectrum holdings from UScellular would put AT&T over the FCC limit in some markets, AT&T asked for this waiver which has yet to be granted. If the waiver is not approved, AT&T might have to scrap or revise its plan to obtain more 3.45GHz spectrum. In a recent filing made with the FCC, AT&T disclosed its 3.45GHz holdings and wrote, " Verizon and T-Mobile hold the majority of the remaining unpaired mid-band spectrum outside the 3.45GHz band. As things currently stand, AT&T 's most realistic catch-up opportunities lie in the 3.45GHz spectrum band. Given the lack of a clear spectrum pipeline or mid-band spectrum auction on the horizon, the secondary market represents the only opportunity for AT&T to catch up in the near- to mid-term."

Wi-Fi industry clashes with mobile operators over additional EU spectrum
A group of 58 internet providers and industry associations urged EU tech chief Henna Virkkunen on Wednesday to free up additional spectrum for Wi-Fi services, setting up a clash with operators seeking the same frequencies for mobile networks. In a letter seen by Reuters, global advocacy group Dynamic Spectrum Alliance called on the European Commission to make the upper 6GHz band available for "unrestrained" Wi-Fi operations. Wi-Fi provides internet access to users but also enables various household devices to connect to networks, including televisions, home appliances and industrial sensors. As consumer demand for high-speed connectivity rises, service providers are looking to expand network capacity, eyeing valuable radio spectrum. Without additional Wi-Fi spectrum, European businesses could face higher costs and restricted access to new technologies, making them less competitive globally, the group said in the letter. "Europe is already behind other countries in adopting the latest Wi-Fi standards," it said. Earlier this month, 12 major telecoms operators urged EU regulators to reserve the same spectrum for 5G and 6G mobile networks, highlighting concerns over U.S. firms seeking more spectrum in Europe. While European countries have been more cautious in their approach, the U.S., Canada, South Korea and several other countries have already allocated portions of the 6GHz band for Wi-Fi use. The Wi-Fi community advocates a shared approach to spectrum compared with mobile operators who seek exclusive access, said Martha Suarez, president of the Dynamic Spectrum Alliance. "Most of the traffic in Europe is indoors. And most of it starts or ends by a Wi-Fi connection. There is always a hype about 5G, 6G, but we should not forget how really users connect to the internet," Suarez told Reuters. The EU Commission is expected to propose a legislative package, the Digital Networks Act, in late 2025, aiming to address connectivity challenges, including a more coordinated approach to spectrum policy across member states. The Radio Spectrum Policy Group, which assists the Commission in developing spectrum policy, is scheduled to meet on June 17.
