You can now restore deleted iCloud files, contacts and calendars

If you’ve ever accidently deleted a file in a cloud service (or worse had someone delete a shared file) you know that any restore feature is a god send. Apple recently launched its own file restore feature for iCloud.com users that resurrects files, contacts, calendars and reminders. The new feature is buried in the Advanced area within Settings and deleted files seem to be available for restore for up to 30 days. While grabbing old files before they disappear forever is a no brainer, iCloud’s restoring of calendar and contacts carries with them warnings that the restored data will overwrite the calendar and contact data currently on your devices. So you want to be careful before you start going back in time with abandon. Calendar restore is especially touchy. If you restore a calendar all your shared calendars will have to be shared again and events will be cancelled and invitations will be resent. This is really only for when something goes horribly wrong with your calendar or contacts and you need to get back to a previous version. If you do decide to restore a calendar or contact and everything goes haywire, all is not lost. The feature grabs a snapshot of your current data and you can just restore that.

Researchers inject oil into cells and create little lasers

The Massachusetts General Hospital research team that lit up human cells with the help of jellyfish genes a few years ago are back with a more advanced version of the technology. This new version forgoes the complicated external mirror setup in favor of injectable oil droplets impregnated with fluorescent dye. This is the same basic idea as what a team from St Andrews University recently created, except that the plastic bead that served as the their laser’s resonating chamber is now an oil droplet. While the technology isn’t ready for therapeutic applications just yet, it does hold a great deal of promise. The problem with conventional cellular markers and dye is that they have a broad emission spectrum which can make it difficult to spot the marked cells amidst the rest of the tissue. But with these miniature lasers, doctors will be able to mark and track individual cells no matter where they are in the body.
