London, Apr 29: Finished drinking your bottle of water? Now eat it! A design student in the UK has developed an edible bottle that could rid the world of excess plastic waste. Rodrigo Garcia Gonzalez, along with fellow students from Imperial College London, has been working on the Ooho water bottle for the past few years.

The bottle is made from edible material, looks like a jellyfish, and has the potential to put an end to the bottled water industry, Smithsonian.com reported.

The Ooho bottle is inspired by the juice-filled pearls added to bubble tea and the creations of legendary Spanish chef Ferran Adria, who uses a technique for encasing liquids in edible membranes known as sheperification.Gonzalez and his team first took a frozen ball of water and dipped it into a calcium chloride solution, which formed a gelatinous layer.

The frozen ball was then soaked in another solution made from brown algae extract, which encapsulated the ice in a second squishy membrane that further reinforced the structure. Keeping the frozen water in the algae solution for long periods of time allowed the mould to become thicker and stronger.

"The main point in manipulating the water as solid ice during the encapsulation is to make it possible to get bigger spheres and allow the calcium and algae to stay exclusively in the membrane," Gonzalez said.

The Ooho has been tested in some European cities, but the researchers need to perfect it, as their edible bottles still don't hold large amounts of water and also can't be resealed. Even with the Ooho's fortified layers, Gonzalez describes the container's strength as comparable to the skin of a fruit. "We're trying to address this with a double container," he said.

Twitter has joined efforts to do away with racially loaded terms such as master, slave and blacklist from its coding language in the wake of the death of African-American George Floyd and ensuing Black Lives Matter protests.

The project started even before the current movement for racial justice escalated following the death of 46-year-old George Floyd in police custody in May.

The use of terms such as "master" and "slave" in programming language originated decades ago. While "master" is used to refer to the primary version of a code, "slave" refers to the replicas. Similarly, the term "Blacklist" is used to refer to items which are meant to be automatically denied.

The efforts to change these terms in favour of more inclusive language at Twitter were initiated by Regynald Augustin and Kevin Oliver and the microblogging platform is now backing their efforts.

"Inclusive language plays a critical role in fostering an environment where everyone belongs. At Twitter, the language we have been using in our code does not reflect our values as a company or represent the people we serve. We want to change that. #WordsMatter," Twitter's engineering team said in a post on Thursday.

As per the recommendations from the team, the term "whitelist" could be replaced by "allowlist" and "blacklist" by "denylist".

Similarly, "master/slave" could be replaced by "leader/follower", "primary/replica" or "primary/standby".

Twitter, however, is not the first to start a project to bring inclusivity in programming language.

According to a report in CNET, the team behind the Drupal online publishing software started using "primary/replica" in place of "master/slave" as early as in 2014.

The use of the terms "master/slave" was also dropped by developers of the Python programming language in 2018.

Now similar efforts are underway at Microsoft's Github and LinkedIn divisions as well, said the report.

Paris, Jun 16: Increasing numbers of readers are paying for online news around the world even if the level of trust in the media, in general, remains very low, according to a report published Tuesday.

Around 20 percent of Americans questioned said they subscribed to an online news provider (up to four points over the previous year) and 42 percent of Norwegians (up eight points), along with 13 percent of the Dutch (up to three points), compared with 10 percent in France and Germany.

But between a third and a half of all news subscriptions go to just a few major media organisations, such as the New York Times, according to the annual Digital News Report by the Reuters Institute.

Some readers, however, are also beginning to take out more than one subscription, paying for a local or specialist title in addition to a national news source, the study's authors said.

But a large proportion of internet users say nothing could convince them to pay for online news, around 40 percent in the United States and 50 percent in Britain.

YouGov conducted the online surveys of 40 countries for the Reuters Institute in January, with 2,000 respondents in each.

Further surveys were carried out in six countries in April to analyse the initial effects of COVID-19.

The health crisis brought a revival of interest in television news -- with the audience rising five percent on average -- establishing itself as the main source of information along with online media.

Conversely, newspaper circulation was hard-hit by coronavirus lockdown measures.

The survey found trust in the news had fallen to its lowest level since the first report in 2012, with just 38 percent saying they trusted most news most of the time.

However, confidence in the news media varied considerably by country, ranging from 56 percent in Finland and Portugal to 23 percent in France and 21 percent in South Korea.

In Hong Kong, which has been hit by months of sometimes violent street protests against an extradition law, trust in the news fell 16 points to 30 percent over the year.

Chile, which has had regular demonstrations against inequality, saw trust in the media fall 15 percent while in Britain, where society has been polarised by issues such as Brexit, it was down 12 points.

Giving each and every app access to personal information stored on Android smartphones such as your contacts, call history, SMS and photos may put you in trouble as bad actors can easily use these access to spy on you, send spam messages and make calls anywhere at your expense or even sign you up for a premium "service", researchers from cybersecurity firm Kaspersky have warned.

But one can restrict access to such information as Android lets you configure app permissions. 

Giving an app any of these permissions generally means that from now on it can obtain information of this type and upload it to the Cloud without asking your explicit consent for whatever it intends to do with your data.

Therefore, security researchers recommend one should think twice before granting permissions to apps, especially if they are not needed for the app to work. 

For example, most games have no need to access your contacts or camera, messengers do not really need to know your location, and some trendy filter for the camera can probably survive without your call history, Kaspersky said. 

While decision to give permission is yours, the fewer access you hand out, the more intact your data will be.

Here's what you should know to protect your data.

SMS: An app with permission to send and receive SMS, MMS, and WAP (Wireless Application Protocol) push messages, as well as view messages in the smartphone memory will be able to read all of your SMS correspondence, including messages with one-time codes for online banking and confirming transactions.

Using this permission, the app can also send spam messages in your name (and at your expense) to all your friends. Or sign you up for a premium "service." You can see and conrol which apps have these rights by going to the settings of your phone.

Calendar: With permission to view, delete, modify, and add events in the calendar, prying eyes can find out what you have done and what you are doing today and in the future. Spyware loves this permission.

Camera: Permission to access the camera is necessary for the app to take photos and record video. But apps with this permission can take a photo or record a video at any moment and without warning. Attackers armed with embarrassing images and other dirt on you can make life a misery, according to Kaspersky.

Contacts: With permission to read, change, and add contacts in your address book, and access the list of accounts registered in the smartphone, an app can send your entire address book to its server. Even legitimate services have been found to abuse this permission, never mind scammers and spammers, for whom it is a windfall.

This permission also grants access to the list of app accounts on the device, including Google, Facebook, and many other services.

Phone: Giving access to your phone means permission to view and modify call history, obtain your phone number, cellular network data, and the status of outgoing calls, add voicemail, access IP telephony services, view numbers being called with the ability to end the call or redirect it to another number and call any number.

This permission basically lets the app do anything it likes with voice communication. It can find out who you called and when or prevent you from making calls (to a particular number or in general) by constantly terminating calls. 

It can eavesdrop on your conversations or, of course, make calls anywhere at your expense, including to pay-through-the-nose numbers, Kaspersky warned.
