** IISc develops device to improve data encryption

‘This will provide better protection for digital data such as credit card details, passwords etc.’

A team at the Department of Electrical Communication Engineering (ECE), Indian Institute of Science (IISc) has developed a true random number generator (TRNG), which, the team says, can improve data encryption and provide improved security for sensitive digital data such as credit card details, passwords and other personal information. The study describing the device has been published in the journal  ACS Nano.

“Almost everything we do on the internet is encrypted for security. The strength of this encryption depends on the quality of random number generation,” explained Nithin Abraham, a PhD student who is a part of a team led by Kausik Majumdar, Associate Professor at ECE, which has developed the device.

India becomes largest producer, second largest exporter of sugar

The government on Wednesday claimed that India has become the largest producer of sugar in the world in the year 2022-23, more than Brazil, while it would be the second largest exporter of sugar.

Sugar production in 2018-19 was 332 lakh metric tonnes (LMT) after discounting diversion of 3 LMT for ethanol; in 2019-20, it was 274 LMT (after discounting diversion of 9 LMT for ethanol); in 2020-21, the production increased to 310 LMT (after discounting diversion of 22 LMT for ethanol) and for 2021-22, it is 335 LMT (after discounting diversion of 35 LMT for ethanol).

The production of sugar has increased and so has sugar exports. In sugar seasons 2017-18, 2018-19 & 2019-20, only about 6.2 LMT, 38 LMT & 59.60 LMT of sugar was exported. “In sugar season 2020-21 against target of 60 LMT, about 70 LMT have been exported. In the current sugar season 2021-22, against the projected 100 LMT exports, contracts for export of about 90 LMT have been signed, about 82 LMT sugar has been dispatched from sugar mills for export and approximately 78 LMT have been exported. Export of sugar in current sugar season 2021-22 is the historically highest,” Subodh Singh, Joint Secretary, Food, told media persons.

About 80 per cent of sugar is produced in Maharashtra, Uttar Pradesh and Karnataka and because the two states south of Narmada are nearer to the ports, export takes place more from these states.

** Money spider, ant-mimicking spider discovered at Wayanad Wildlife Sanctuary

Discovery by researchers of Christ College, Irinjalakuda

Money spiders, commonly found in European meadows, have been reported for the first time in the country from the Muthanga range of the Wayanad Wildlife Sanctuary. The species is called so as it is “believed to bring luck” to the person who comes in contact with it.

Researchers of Christ College, Irinjalakuda, Thrissur, have discovered the spider that belongs to the family of dwarf spiders ( Linyphiidae) under the genus  Prosoponoides. It has been given the name  Prosoponoides biflectogynus.

“Only six species of spiders belonging to this genus have been identified from across the world so far. It is the first report of this genus from India and hence no extensive studies have been conducted on this species of spiders in the country,” said Dr. Sudhikumar A.V., Head, Department of Zoology, Christ College.

** India registers success with BP treatment, control

The India Hypertension Control Initiative, started in 2018, has been expanded to more than 100 districts

Cardiovascular diseases (CVD) are the leading cause of death among adults in India. One of the major drivers of heart attack and stroke is untreated high blood pressure or hypertension. Hypertension is a silent killer as most patients do not have any symptoms.

India has more than 200 million people with hypertension, and only 14.5% of individuals with hypertension are on treatment. Unlike many other diseases, hypertension is easy to diagnose and can be treated with low-cost generic drugs.

India Hypertension Control Initiative (IHCI) is a multi-partner initiative involving the Indian Council of Medical Research, WHO-India, Ministry of Health and Family Welfare, and State governments to improve blood pressure control for people with hypertension. The project initiated in 26 districts in 2018 has expanded to more than 100 districts by 2022. More than two million patients were started on treatment and tracked to see whether they achieved BP control.

** Glimpses of tribal freedom struggle at Ranipur police museum

With a history dating back to colonial years, the heritage building that once housed the police station is now a treasure trove of information on tribal revolutionaries.

Most visitors will mistake it for any other nondescript structure. But the Ranipur police museum is special. With a history dating back to colonial years, the heritage building that once housed the police station is now a treasure trove of information on tribal revolutionaries.

Betul district police chief Simala Prasad said the Ranipur police station functioned from the building from 1913 to 2016 before it was shifted to a new address. The building, meanwhile, was lying abandoned for the last six years.

“Local residents wanted us to preserve the erstwhile police station as a heritage building as it holds an integral place in the history of freedom struggle involving tribals. We consulted local historians and decided to turn the historic police station into a museum. The museum has a special section dedicated to the tribal revolutionaries from Betul which includes the likes of Vishnu Singh Uike and Ganjan Singh Korku,” the Betul SP informed.

The region has a rich history when it comes to the freedom struggle of indigenous communities. In 1942, freedom movement hero Vishnu Singh Uike led fellow revolutionaries to attack the Ranipur police station. They had even tried to set the police station ablaze.

** Skyroot successfully test fires space launch vehicle ‘Vikram-1’ rocket stage

Named ‘Kalam-100’ after the renowned Indian rocket scientist A.P.J. Abdul Kalam.

Skyroot Aerospace, the national-award winning startup building India’s first privately built space launch vehicles has announced the successful completion of a full duration test-firing of its ‘Vikram-1’ rocket stage, representing a major milestone for the company on Thursday.

Named ‘Kalam-100’ after former President and the renowned Indian rocket scientist A.P.J. Abdul Kalam, the third stage of ‘Vikram-1’ produces a peak vacuum thrust of 100 kN (or ~10Tons) and has a burn time of 108 sec, said the city based firm’s founders, in an official release.

The rocket stage has been built with high-strength carbon fiber structure, solid fuel, novel thermal protection system, and carbon ablative nozzle. “It’s a highly reliable stage with no moving parts and high level of automation in manufacturing. This testing will help us in development of orbital vehicle Vikram-1 and gives great confidence for our other rocket stages planned to be tested soon,” said Chief Executive Officer (CEO) and co-founder Pawan Kumar Chandana.
