The work combines Prakash’s expertise in manipulating droplet fluid dynamics with a fundamental element of computer science – an operating clock. “In this work, we finally demonstrate a synchronous, universal droplet logic and control,” said Prakash.
Because of its universal nature, the droplet computer can theoretically perform any operation that a conventional electronic computer can crunch, although at significantly slower rates. The ability to precisely control droplets using fluidic computation could have a number of applications in high-end biology and chemistry and scalable digital manufacturing.
Computer clocks are responsible for everything – smartphones, airplanes and internet. Developing a clock for a fluid-based computer required some creative thinking. Prakash realised that a rotating magnetic field that could act as clock to synchronise all the droplets might do the trick. The team built arrays of tiny iron bars on glass slides. They then laid a blank glass slide on top and sandwiched a layer of oil in between.
Then they carefully injected into the mix individual water droplets that had been infused with tiny magnetic nano-particles. Next, they turned on the magnetic field. Every rotation of the field counted as one clock cycle and every drop marched exactly one step forward with each cycle. A camera recorded the interactions between individual droplets, allowing observation of computation as it occurs in real time.
Prakash and his colleagues, however, have a more ambitious application in mind. Their goal is to build a completely new class of computers that can precisely control and manipulate physical matter.
“Imagine when you run a set of computations wherein not only information is processed but also the physical matter is algorithmically manipulated. We have just made this possible at the mesoscale,” Prakash said.
The results were published in the journal Nature Physics.
She took to Instagram to share her experience, detailing that doing all that over the six months period left her with "permanent stretch marks". "Gaining 20 kgs in 6 months and loosing it all within 6 months that too in my thirties messed up many things in my bodya I also have permanent stretch marks as well but art comes to life with a price and more often than not price is the artist him/herself," she wrote.
"Thalaivii" showcases the varied aspects of Jayalalithaa's life, tracing her journey as an actress at a young age to becoming the face of Tamil cinema, as well as the rise of the revolutionary leader who changed the course of the state's politics. Talking about her upcoming works, Kangana currently has 'Dhaakad'.
She is also shooting for her next 'Tejas', where she plays a fighter pilot. The Indian Air Force was the first of the country's defence forces to induct women into combat roles in 2016. The film takes inspiration from the landmark event. 'Tejas' is directed by debutant Sarvesh Mewara. The film will be RSVP's second film which pays a tribute to the Indian military after the immensely successful film "Uri: The Surgical Strike" which was released in January 2019. (IANS/ MBI)

The status website says the encrypted messaging app is "experiencing technical difficulties" and many people are also getting an in-app error message that says the same thing. Signal allows for secure and encrypted video, voice and text communication, but users are unable to send any messages.
According to Downdetector.com, users started reporting outages around 11:05 PM Eastern Standard Time and it appears to be affecting people around the world. Comments shared on Downdetector.com indicates that Signal was down for users from India, US, Germany, New Zealand, Netherlands, Australia, Brazil and many other countries.
"Down in Midwest USA. Signal was started by people connected to which secret 3-letter organization? (Look it up) Yep, that's right! An app disguised a privacy app to trick you into sharing more private information than you would with another messaging app," a user said. "I think Signal is having a rough day. Good luck, Team Signal. I'm sure you'll have it sorted out in a snap," said another. The encrypted messaging service has climbed to the top spot in the free apps category of the App Store in multiple countries, including India. (IANS/ MBI)

Apple has acknowledged an issue where the "unlock with Apple Watch" feature might not work with its new iPhone 13 devices and promised to fix this issue with an upcoming software update. "You might see 'Unable to Communicate with Apple Watch' if you try to unlock your iPhone while wearing a face mask, or you might not be able to set up Unlock with Apple Watch," the iPhone maker said in the support document.
This issue will be fixed in an upcoming software update. Until the update is available, you can turn off Unlock with Apple Watch and use your passcode to unlock your iPhone 13. To turn off Unlock with Apple Watch, go to Settings > Face ID & Passcode.
Earlier, multiple users found that they cannot unlock their iPhone 13 with the Apple Watch and instead received an error. User Monzilla88 on Reddit first reported the issue to the subreddit r/AppleWatch. They stated that both their iPhone 13 Pro and Apple Watch SE are up to date with the newest iOS and watchOS updates.
"Whenever I try to enable unlock with Apple Watch on my phone I get an error saying "Unable to communicate with Apple Watch," they posted. Monzilla88 claimed that they had tried unpairing and repairing, hard resetting both devices, turning on and off passcodes, but not no avail, the report said. More than 20 other users self-reported the same problem, with others noting that the feature works fine on iOS 15 on older models of iPhone, including the iPhone 11 Pro Max and the iPhone X.
