Surveillance footage obtained from a Las Vegas phone store shows video shows an iPhone exploding on a desk while an employee sat just a couple feet away.The employee quickly jumped up to get help as the phone burned itself out on the desk in less than 20 seconds.The phone screen was being replaced after it cracked due to heat damage as the battery expanded.The store is not being identified.Paul Tartaglio owns Gadget Repair. While it wasn't his shop, he says he has seen badly damaged batteries due to heat in the Las Vegas desert.He has seen a phone explode before but "It takes a lot for it to explode."The biggest issue he sees the temperatures rise into the triple digits in Las Vegas are the cracked screens from warped batteries. "Over time, the batteries heat up and bloat," Tartaglio said. "The problem is when it bloats up just a little bit, it can cause your screen to crack a lot easier."While he says it's extremely difficult to predict when a battery could explode, Tartaglio said the key is to keep phones out of direct sunlight during the summer.Not only can it lead to explosions in extreme cases, but it can also shorten the life of the battery —especially after the phone issues a temperature warning a few times.Smart phone users should also avoid overcharging devices, which can generate extra heat in the battery.Tartaglio also recommends people use replacement batteries directly from the phone's manufacturer, saying they are often more reliable than aftermarket batteries and typically aren't any more expensive. 1597

Sticking to a normal daily rhythm -- being active during the day and sleeping at night -- can have more benefits than you might expect.A new study found that it is linked to improvements in mood and cognitive functioning as well as a decreased likelihood of developing major depression and bipolar disorder.The study, published Tuesday in the journal The Lancet Psychiatry, looked at disruptions in the circadian rhythms -- or daily sleep-wake cycles -- of over 91,000 adults in the United Kingdom. It measured these disruptions using a device called an accelerometer that is worn on the wrist and measures one's daily activity levels. The participants were taken from the UK Biobank, a large cohort of over half a million UK adults ages 37 to 73.The researchers found that individuals with more circadian rhythm disruptions -- defined as increased activity at night, decreased activity during the day or both -- were significantly more likely to have symptoms consistent with bipolar disorder or major depression. They were also more likely to have decreased feelings of well-being and to have reduced cognitive functioning, based on a computer-generated reaction time test.For all participants, activity levels were measured over a seven-day period in either 2013 or 2014, and mental health proxies such as mood and cognitive functioning were measured using an online mental health questionnaire that participants filled out in 2016 or 2017."It's widely known that a good night's sleep is a good thing for well-being and health. That's not a big surprise," said?Dr. Daniel Smith, professor of psychiatry at the University of Glasgow and a leading author on the study. "But I think what's less well-known and what comes out of this work is that not only is a good night's sleep important, but having a regular rhythm of being active in daylight and inactive in darkness over time is important for mental well-being."The findings were found to be consistent even when controlling for a number of influential factors including age, sex, lifestyle, education and body mass index, according to Smith."I think one of the striking things that we found was just the consistency in the direction of our association across everything we looked at in terms of mental health," Smith said.Daily circadian rhythm is controlled by a collection of neurons in an area of the brain called the hypothalamus. The hypothalamus helps regulate a number of important behavioral and physiological functions such as body temperature, eating and drinking habits, emotional well-being and sleep, according to the?National Institute of General Medical Sciences.The findings are consistent with research indicating a link between sleep disruptions and mood disorders. A 2009 study, for example, showed that men who worked night shifts for four years or more were more likely to have anxiety and depression than those who work during the day.However, the new study is the first to use objective measurements of daily activity and is among the largest of its kind, according to?Aiden Doherty, senior research fellow at the University of Oxford, who was not involved in the research."This study is the first large-scale investigation of the association of objectively measured circadian rhythmicity with various mental health, well-being, personality and cognitive outcomes, with an unprecedented sample size of more than 90 000 participants," Doherty wrote in an email."Previous studies have been very small (in just a few hundred people), or relied on self-report measures (asking people what they think they do). ... However, this study used objective device-based measures in over 90,000 participants; and then linked this information to standard measures of mood disorders, subjective well-being, and cognitive function," he added.The findings have significant public health consequences, particularly for those who live in urban areas, where circadian rhythms are often disrupted due to artificial light, according to Smith."By 2030, two-thirds of the world's population will be living in cities, and we know that living in an urban environment can be pretty toxic to your circadian system because of all the artificial light that you're exposed to," Smith said."So we need to think about ways to help people tune in to their natural rhythms of activity and sleeping more effectively. Hopefully, that will protect a lot of people from mood disorders."For those who struggle to maintain a consistent circadian rhythm, certain strategies -- such as avoiding technology at night -- have proven to be an important part of good sleep hygiene."Not using your phone late at night and having a regular pattern of sleeping is really important," Smith said. "But equally important is a pattern of exposing yourself to sunshine and daylight in the morning and doing activity in the morning or midday so you can actually sleep properly."Based on the observational nature of the study, the researchers were unable to show causality, meaning it is unclear whether the sleep disturbances caused the mental health problems or vice versa."It's a cross-sectional study, so we can't say anything about cause and effect or what came first, the mood disorder or the circadian disruption," said Kristen Knutson, associate professor of neurology at Northwestern's Feinberg School of Medicine, who was not involved in the study."And it's likely they affect each other in a circular fashion," she added.The researchers also looked exclusively at adults between age 37 and 73, meaning the results may not apply to younger individuals, whose circadian rhythms are known to be different than those of older adults, according to Smith."The circadian system changes throughout life. If you've got kids, you know that very young kids tend to be nocturnal," Smith said. "My suspicion is that we might observe even more pronounced effects in younger samples, but that hasn't been done yet, to my knowledge."But the study adds more credence to the idea that sleep hygiene -- including maintaining a consistent pattern of sleep and wake cycles -- may be an important component of good mental health, according to Smith."It's an exciting time for this kind of research because it's beginning to have some real-world applications," Smith said. "And from my point of view as a psychiatrist, I think it's probably under-recognized in psychiatry how important healthy circadian function is, but it's an area that we're trying to develop." 6496

Taylor Swift?is helping a fan of hers in need.The singer donated ,500 to a GoFundMe page that is raising money for the family of a mother, Lauriann Bartell, who has been in a coma for the past three years.Bartell's 19-year-old daughter, Sadie Bartell, tweeted a link to the GoFundMe page and said that her mother went into a coma two days before she went to see Swift in concert. "Hey guys. I'm really nervous to post this. Please help if you can and pray for my family. I'm sorry I never said anything sooner and that I'm suddenly asking for help. I love you guys so much," she wrote in a message she posted with the tweet.She added, "I'm grateful to Taylor for keeping me afloat through it all."Swift made the donation to the online platform over the weekend with the message, "Love, Taylor, Meredith and Olivia Swift." Meredith and Olivia are her two cats.Bartell took to Twitter after Swift's donation and posted a message in disbelief. "Taylor really actually donated to me and followed me and liked my thank you to her like that actually happened it's my life it's real," she tweeted.She went on to post a more lengthy message on Facebook, "Everyone who knows me knows that Taylor Swift is my whole entire life. She has been there for me more than anyone. I really, truly, would not be who I am without her. Today she read my family's story online and out of the goodness of her heart donated to us. She shows up every time I need her. She always has and she always will. I wish that I could express how much it means to me that ANYONE has helped my family over the years, let alone Taylor."Bartell added, "She is the light at the end of the tunnel and is truly the best thing that has ever happened to me. I will never be able to comprehend this. She is a miracle in herself. She just gave my family exactly what we need to carry on. This sounds so composed and so collected but in reality I've been crying for hours and my hands are shaking so hard I can barely type this. Taylor Swift, I love you more than I could ever say. Thank you for this. And for everything else. Forever on your side and thanks for being on mine."CNN has reached out to Swift's representative for comment. 2204

Steven Bochco, a producer whose boundary-pushing series like "Hill Street Blues" and "NYPD Blue" helped define the modern TV drama, died Sunday after a battle with leukemia. He was 74.Bochco died Sunday morning at home, surrounded by family, according to Phillip Arnold, Bochco's personal assistant.Bochco co-created several of TV's most popular programs, while his large ensemble casts and ambitious storytelling set a benchmark beginning in the early 1980s that he refined and built upon for more than 30 years. Bochco also consciously set out to establish new, more permissive standards for broadcast television with "NYPD Blue," meticulously negotiating what was acceptable in terms of language and nudity with then-ABC Entertainment chief (and now CEO of the Walt Disney Co.) Robert Iger, even drawing naked figures to help set the ground rules. 858
