Scientists have developed a battery-free hand-held video game console or 'Game Boy' that harvests energy from the user to allow infinite gameplay.
“But this Game Boy is not just a toy. It's a powerful proof-of-concept that pushes the boundaries of battery-free intermittent computing into the realm of fun and interaction," the researchers at Northwestern University and the Delft University of Technology (TU Delft) in the Netherlands, wrote.
Instead of batteries, which are costly, environmentally hazardous and ultimately end up in landfills, this device harvests energy from the sun — and the user. These advances enable gaming to last forever without having to stop and recharge the battery.

“It's the first battery-free interactive device that harvests energy from user actions. When you press a button, the device converts that energy into something that powers your gaming," said study co-author Josiah Hester.
“Sustainable gaming will become a reality, and we made a major step in that direction — by getting rid of the battery completely," said TU Delft's Przemyslaw Pawelczak.
“With our platform, we want to make a statement that it is possible to make a sustainable gaming system that brings fun and joy to the user," Pawelczak added.
The researchers' energy-aware gaming platform (ENGAGE) has the size and form factor of the original Game Boy, while being equipped with a set of solar panels around the screen. Button presses by the user are the second source of energy. Most importantly, it impersonates the Game Boy processor. Although this solution requires a lot of computational power, and therefore energy, it allows any popular retro game to be played straight from its original cartridge.
As the device switches between power sources, it does experience short losses in power. To ensure an acceptable duration of gameplay between power failures, the researchers designed the system hardware and software from the ground up to be energy-aware as well as very energy efficient. They also developed a new technique for storing the system state in non-volatile memory, minimizing overhead and allowing quick restoration when power returns.
This eliminates the need to press “save" as seen in traditional platforms, as the player can now continue gameplay from the exact point of the device fully losing power — even if Mario is in mid-jump.
On a not-too-cloudy day, and for games that require at least moderate amounts of clicking, gameplay interruptions typically last less than one second for every 10 seconds of gameplay.
The researchers found this to be a playable scenario for some games — including Chess, Solitaire, and Tetris — but certainly not yet for all (action) games.
The research team will present the study virtually at UbiComp 2020, a major conference within the field of interactive systems, on September 15. (IANS)
Hackers have stolen crypto tokens worth $120 million from Blockchain-based decentralised finance (DeFi) platform BadgerDAO. Several crypto wallets were drained before the platform could stop the cyber attack. In a tweet, Badger said it has received reports of unauthorised withdrawals of user funds. "As Badger engineers investigate this, all smart contracts have been paused to prevent further withdrawals. Our investigation is ongoing and we will release further information as soon as possible," the company said late on Thursday.
According to the blockchain security and data analytics Peckshield, the various tokens stolen in the attack are worth about $120 million, reports The Verge. According to reports, someone inserted a malicious script in the user interface (UI) of their website. Badger has retained data forensics experts Chainalysis to explore the full scale of the incident and authorities in both the US and Canada have been informed. "Badger is cooperating fully with external investigations as well as proceeding with its own," it said. DeFi is a collective term for financial products and services that are open, decentralised and accessible to anyone. DeFi products open up financial services to anyone with an internet connection and they are largely owned and maintained by their users. While the attack didn't reveal specific flaws within Blockchain tech itself, it managed to exploit the older "web 2.0" technology that most users need to use to perform transactions, according to reports.

A total of 120 top Bollywood and other celebrities are expected to attend the wedding of film stars Katrina Kaif and Vicky Kaushal which is scheduled on December 9 in Rajasthan, said Rajendra Kishan, the District Collector (DC) of Sawai Madhopur district of the state on Friday. The District Collector told mediapersons: "These 120 guests shall follow all COVID-19 protocols and fully vaccinated guests will get entry in the much-hyped celebrity wedding."
Kishan said that the organisers have been asked to strictly follow all Covid-19 protocols. Also, those who are not vaccinated, will not be allowed without the negative RT-PCR test report, he added. "We have been informed by organisers that a total of 120 guests are invited to the wedding and the events will take place between December 7 to December 10," he added.
Earlier at 10.30 a.m., Kishan called a meeting which was attended by administrative, police and forest department officials, hotel and event managers to ensure adequate arrangements for crowd control, smooth regulation of traffic, and law and order situation amid the VIP movement. The wedding venue Fort Barwara, that has been converted into a heritage hotel, is situated in the panchayat samiti Chauth Ka Barwara. The venue is around 22 km away from Sawai Madhopur and is around 174 km from Jaipur. Sawai Madhopur district is famous for the Ranthambore National Tiger Reserve and as per reports, the guests are likely to be taken for a tiger safari. (IANS/ MBI)

The National Centre for Biological Sciences (NCBS), which confirmed the first two cases of the Omicron variant in Bengaluru on Thursday, is continuously monitoring the situation in four cities - Bengaluru, Hyderabad, New Delhi, and Pune. The NCBS is a part of a consortium of national laboratories performing genomic surveillance across four city clusters. The consortium was established four months ago with support from The Rockefeller Foundation's Pandemic Prevention Institute, and is led by the Centre for Cellular and Molecular Biology (CCMB) in Hyderabad.
Dr Rakesh Mishra at the CCMB said on Friday that the consortium is continuously monitoring the situation in all the four cities and has upscaled its efforts to sequence as many samples as possible Apart from the CCMB and the NCBS, the consortium includes CSIR-Institute of Genomics and Integrative Biology - IGIB in New Delhi and the Pune Knowledge Cluster, Indian Institute of Science Education and Research (IISER), Pune, and CSIR-National Chemical Laboratory in Pune.

The consortium is focused on upscaling genomic surveillance as part of national efforts led by the INSACOG - Indian SARS-CoV-2 Genomics Consortium - to respond to the Covid-19 pandemic. The consortium intensified its sequencing efforts after the World Health Organisation announced Omicron as a Variant of Concern. Such an intensified effort enabled the Bengaluru team at the NCBS, a member laboratory of INSACOG, in collaboration with Strand Life Sciences and the Bruhat Bengaluru Mahanagara Palike (BBMP), to detect, rapidly sequence and verify the existence of the omicron variant in samples from two Covid-19 infected individuals.
They hope this will aid in a rapid response to contain the spread of variants of concern. Prof Satyajit Mayor from the NCBS conveyed the information to local and national authorities, and the Indian government released a statement on December 2, all within four days of receiving the samples. Both SARS-CoV-2 genomes have also been uploaded to the global repository for SARS-CoV-2 sequences, GISAID, so that they can be publicly available to the scientific community, the NCBS said.
