Facebook announces two new features for live videos 

The viewers interact a lot with what is happening through the comments. According to Facebook itself, users comment about 10 times more on live videos than normal videos. This ends up generating a situation that may be a bit messy for those watching the broadcast.

To try to lighten the situation a bit, Facebook now allows you to follow alive only in the company of your friends through Live Chat With Friends.

So every time you follow a live stream via Facebook, you'll be able to invite your interested friends and exchange ideas with them only, without the interference of thousands of other users and all the chaos that so many messages end up causing.

Another novelty that is already rolling in the version of Facebook for iOS is Live With, a tool that allows you to stream live video with two users at the same time without being together, that is, you can start streaming and Invite a Friend to join the life. His video will join his side-by-side format or PIP, where a small screen appears in the corner of the broadcast.

Scientists work on clothes that are ventilated and perfumed from sweat

Scientists at the Massachusetts Institute of Technology (MIT) have been working on a prototype jacketed T-shirt that can automatically ventilate and sent in response to sweat.

According to Wen Wang, who led the study and wrote the paper on the wearable bio-hybrid in the journal Science Advances, the bacterium B. subtitles were used in the middle of two layers of latex. The inner part, closer to the skin, relaxes by absorbing perspiration and bending, opening up a space for airflow.

But it is not possible to wash. Yet…

Wang also said that the process works even if the bacteria are dead, because of the elements of the cells, such as DNA and polysaccharides, fold in response to the mixture. However, in order for the project to be taken to the market, it is necessary to overcome a problem: the laundry can not be washed, otherwise the bacteria can be carried by the water.

The solution would be to create a way of chemically attaching it to a fabric or embedding it in the yarns of the fabric.

And the researcher goes further, saying that she even idealizes a way to use living microorganisms to digest those drops of wine or blood that have soiled her clothes.
