  • How to switch from iCloud Photos to just plain Photos
    iCloud Photos provides a great service. Deeply embedded into iOS, iPadOS, macOS, and iCloud, with the feature enabled, every photo you take and every video you record is automatically uploaded to your central iCloud account and then synchronized as a thumbnail or full-resolution image to all your devices linked to the same iCloud account that also have iCloud Photos enabled.As photo collections grow, some people balk at paying Apple for increasing amounts of iCloud storage, however, and they don’t need or want synchronization across all their devices in quite this way.You can shed the iCloud part of iCloud Photos and stick just to Photos if you like. You can then opt to sync a different way if you still want that feature—and at no cost.To read this article in full, please click here

  • How iCloud Drive works with multiple users on a single Mac
    Apple introduced fast user switching years ago to allow easier shared use of a single Mac by multiple people. After logging into an account and switching away from it, all the activities that were underway continue on their merry progress even while another user has logged in or switched to the foreground.This includes iCloud Drive, Dropbox, and other sync apps that carry out their operations in the background during a normal session. This can be useful if multiple people rely on synchronized files, preventing them from having to log in and wait for updates to occur.Apple assures its third-party developers in fast user switching documentation that background accounts have no keyboard or mouse input, and apps that check on screen activity will receive a response as if the screen were asleep. That is a sort of guarantee that any app or service that’s running will reliably keep running.To read this article in full, please click here
  • Find My: How to use Apple’s new all-in-one app to find friends and devices
    Find My Friends was not the first location-sharing app when it was introduced in 2011, but by being a first-party solution, it saw incredibly widespread support. So much so that Apple just went ahead and bundled with with iOS starting with iOS 9. Find My iPhone first launched as a MobileMe service in 2010, and became a free iCloud service in 2011. It has been a critical piece of infrastructure to help people locate their lost gear.The ubiquity of these services have made them so popular, so oft-used and reliable, that they have become a mainstay of the Apple ecosystem; a reason to stick with Apple, just like iMessage.With iOS 13 and macOS Catalina, Apple has given these location services their biggest overhaul yet. Since the two apps essentially do the same thing, they have been combined into a single app called “Find My” with a new interface. It’s included in iOS 13, iPadOS 13, and macOS Catalina.To read this article in full, please click here

  • With Catalina, the Mac leans on Apple’s other devices
    Ever since the introduction of the iPod in 2001, Apple has had to navigate the intricacies of a multi-device ecosystem. In the earliest of days, that meant dealing with the iPod as an ancillary media device, reliant upon a Mac (or later a PC) for everything from activation to syncing media.Over the last twelve years, the Apple ecosystem has gotten only more complex, with the addition of iPhones and iPads, the Apple TV, the Apple Watch, AirPods, the HomePod, and more. And while the Mac may be the elder statesperson of this assemblage, it’s found its responsibilities decentralized. No longer does the iPhone or iPad require a Mac just to function; newer devices like the Apple Watch and HomePod never have.To read this article in full, please click here

  • Self-reported suicide attempts rising in black teens as other groups decline
    Self-reported suicide attempts rose significantly in African American teens, while they fell in teens of other ethnic backgrounds throughout an almost 20-year study. Researchers report suicide attempts increased at an accelerating rate in African American female teenagers, even as overall female suicide attempts declined.
  • Is bipolar disorder associated with increased risk of Parkinson’s disease?
    Study reveals patients with bipolar disorder have a significantly increased risk of developing Parkinson's disease compared with the general population.
  • Dementia spreads via connected brain networks
    A new brain mapping study allows for individual predictions of the progression of frontotemporal dementia.
  • Gut immunity more developed before birth than previously thought
    The fetal gut has far better developed immune capabilities than previously thought. The findings could help develop new maternal vaccines and provide early insight into potential autoimmune disorders, which may occur later in life.
  • Researcher uses sweat monitors to predict behavioral issues in adolescents severely affected with autism
    Electrodermal activity, which results in an increased level of sweat, was able to determine when an adolescent with server ASD was about to embark on aggressive behavior 60% of the time.
  • New genetic link found for some forms of SIDS
    Researchers tie some cases of sudden infant death syndrome (SIDS) with a genetic mutation that causes an inability to process milk, leaving the child vulnerable to sudden heart failure. Future studies will explore if a drug called Elamipretide can help reduce cardiac events in children with the mutation.
  • ‘Sticky’ gene may help Valium calm nerves
    A new study challenges existing theories about how benzodiazepines, such as valium, work to calm nerves. Researchers report a 'sticky' gene called Shisa7 plays a critical role in the regulation of inhibitory neural circuits, and the sedative effects benzodiazepines have on circuit activity.
  • Rare sleep disorder common among veterans with PTSD
    21% of veterans who experience PTSD or traumatic brain injury suffer from a rare sleep condition that affects less than 1% of the general population. The condition, REM sleep behavior disorder (RBD), is characterized by an impairment of sleep-related muscle paralysis, causing people to act out dreams during REM sleep. The uncontrolled actions often cause harm to the sufferer of their partners.
  • Habitual tea drinking modulates brain efficiency
    Habitual tea drinking was associated with greater functional connectivity in the default mode network. Findings suggest tea drinking has a positive contribution to brain structure and a protective effect on age-related decline in brain organization.
  • Slower walkers have older brains and bodies at 45
    Slower walkers have accelerated aging in middle age, both physically and cognitively. Tests given to measure IQ, language, motor skills, and emotional control at age 3, can predict walking speed and thus accelerated aging during middle age.
  • Compound in breast milk fights harmful bacteria
    Glycerol monolaurate (GML), a compound found in human breast milk, fights against the effects of harmful bacteria while allowing beneficial bacteria to thrive. GML also inhibits inflammation in epithelial cells, helping to prevent both bacterial and viral infections of the gut. GML is 200 times higher in human breast milk than cow milk. Researchers propose adding GML to infant formula and cow milk given to small children.
