Los Angeles Testing Reflective Roads to Keep Neighborhoods Cool

The urban heat island effect is a well-documented part of city living. Cities are simply hotter than their surrounding regions, thanks to their miles and miles of dark surfaces like asphalt roads, brick buildings, and black tar roofs that absorb heat during the day. When night falls, these hard surfaces release the heat they’ve been taking in all day, keeping cities several degrees hotter than their greener neighbors long after the sun has set. Green roofs and more parklands help, but they can't cancel out the enormous areas of paved surfaces in most metropolises.

In Los Angeles, authorities are combating the hot temperatures of the park-poor city by installing California’s first reflective road coatings designed to reduce temperatures, according to the Los Angeles Daily News and Curbed Los Angeles.

Called CoolSeal, the gray, reflective coating is designed to keep roads from absorbing heat, cooling their surroundings accordingly. So far, it has been installed on a half-block of road in Canoga Park, and 14 other Los Angeles neighborhoods will be piloting CoolSeal-coated roads by the end of June. To deploy it across the city will cost $40,000 a mile, according to current estimates, and the coating will last about seven years.

There is plenty of asphalt to cover, making the endeavor both expensive and very worthwhile. Los Angeles County has more than 21,700 miles of roads and 200 square miles of parking spaces, resulting in the greatest urban heat island effect in the state of California—increasing temperatures by up to 19°F in some places.

Earlier this year, Los Angeles Mayor Eric Garcetti announced an initiative to lower the average temperature in the Los Angeles area by 3°F over the next two decades. In a two-year test by the city and CoolSeal's manufacturer, the coating decreased average summer temperatures in the parking lot of a sports complex in the Sepulveda Basin recreational area from 160°F to 135-140°F.

A few gray roads could help make sure no one ever tries to fry an egg on the sidewalk again.

Stuck in a Never-Ending Group Chat? Here's How to Stop It

The more contacts on your phone, the more likely you will be periodically pulled into the dreaded group chat—a meandering, pestering chain of communication on apps like Facebook or WhatsApp that keeps your cell in a constant state of alert. While some group chats start out informative, they can quickly devolve in utter banality. (One warning sign: a funny nickname for the chat.) How can one free themselves from this chorus and get on with their lives?

David Nield at Gizmodo recently broke down the steps you can take to pull yourself free, though it depends on which chat app you’re using. If it’s WhatsApp, for example, you can go to Settings, Account, Privacy, Groups, and then set who can add you to a group chat. That way, only people in your inner circle can loop you in. If someone who isn't on your approved list adds you to a chat, you'll get a direct message inviting you to join, which you can accept or ignore. If you’re already in group chat hell, WhatsApp will allow you to mute notifications by tapping on the Menu button and selecting Mute Notifications.

Facebook Messenger doesn’t allow you to pre-emptively opt out, but you can exit existing group chats by tapping “i” inside the thread and selecting “Leave Group” in Android or tapping the chat thread and clicking “Leave Group” in iOS.

The same is true of Apple’s iMessenger—you can’t insulate yourself from chats. Once it starts, though, you can leave by tapping the top of the conversation, selecting “i,” and selecting either Hide Alerts (which mutes the chat) or Leave This Conversation. If people in the chat are using SMS, the messages will still come through, however. They have to be either muted or removed from your phone and life entirely.

Veterans Can Now Access Their Health Records Through Apple’s Health App

Apple’s iOS Health app is great for more than just checking how many steps you took during a lengthy walk in the park—it also stores health records from Johns Hopkins, Quest Diagnostics, Allscripts, and more than 400 other healthcare organizations.

Now, Fortune reports that the U.S. Department of Veterans Affairs (VA) has joined that list, making it easier than ever for military veterans who receive healthcare through the Veterans Health Administration to access all of their health records, including medications, immunizations, lab results, and other information. In the press release, Apple explains that the app will automatically update the records, so all veterans need to do is log into their providers’s patient portals through the Health app for a “single, integrated snapshot of their health profile whenever they want, quickly, and privately.”

Though the official announcement coincides nicely with Veterans Day on Monday, the change itself has been in the works for several months—the VA released the new feature to certain patients over the summer.

According to its website, the Veterans Health Administration is the largest integrated healthcare system in the country, servicing more than 9 million patients across 1255 healthcare facilities. With such an expansive network, any successful attempt to streamline processes and improve the flow of information—especially when it comes to sensitive, personal data—has the potential to be a major game-changer for veterans.

“Helping veterans gain a better understanding of their health is our chance to show our gratitude for their service,” Apple COO Jeff Williams said in the press release. “By working with the VA to offer Health Records on iPhone, we hope to help those who served have greater peace of mind that their healthcare is in good hands.”

Wondering what you can do to help veterans? Here are 11 honorable ideas.
