• SNAPCHAT, the popular visual messaging service, is giving users a new way to save old “snaps” they shared with friends.

The tool, called Memories, lets you save content on the app that was previously ephemeral. This includes photos, videos or photo montages called “stories”. You can later scroll through them or send them on to your contacts.

While it was already possible to save snaps to your phone’s camera roll, Memories lets users save them privately within the Snapchat app.

The update will become available to Snapchat users over the next month. To find the Memories tool, open Snapchat and swipe up from your camera screen.

• BAHAMIANS familiar with the basic aluminum hurricane shutters that block light from their homes during a storm may be interested to learn that in America a new type of translucent shutter “AstroGuard” is being marketed by hurricanefabric.com.

The shutter is claimed to be a high strength, high tenacity hybrid fabric that offers great hurricane protection and is translucent, eliminating that “in-a-cave feeling associated with other forms of hurricane protection”. The panels come 100in high and 204in wide, can be cut to size easily and come in a tan colour.

• FACEBOOK is adding to its Messenger app this summer an option for encrypted chats that can only be read on devices where they are sent or received.

Users also will be able to set a timer to control how long the message remains visible to anyone, the company announced.

The “secret conversations” feature, which is optional, does not work across different devices. So even if a person has Messenger on a phone and on a computer, the conversation will be visible on only one device.

WhatsApp, the Facebook-owned messaging service, already uses end-to-end encryption on all messages.

• TWITTER says it will live-stream CBS News’ online coverage of the Republican and Democratic conventions later this month, a first for the social media outlet.

People will be able to watch video of the conventions on mobile devices and desktops alongside a feed of political tweets, the company said on Monday. The Republican convention in Cleveland begins on July 18, with the Democrats in Philadelphia the following week.

Besides being the latest example of Twitter’s foray into video, the announcement is a major shot of exposure for CBSN, which is CBS News’ two-year-old live online stream.

• AN experimental solar-powered airplane is due to arrive in Egypt today on the penultimate leg of its globe-circling voyage.

Organisers said the Solar Impulse 2 flew from Seville, Spain, on Monday and was heading for Cairo on a flight expected to last 50 hours.

The around-the-world voyage began in March, 2015, in Abu Dhabi in the United Arab Emirates and is due to finish there too.

The plane arrived in Seville on June 23 after an unprecedented three-day flight across the Atlantic.

The wings of Solar Impulse 2 are equipped with 17,000 solar cells that power propellers and charge batteries. The plane runs on stored energy at night.
