DRDO Handed Over The Motor Bike Ambulance Rakshita To CRPF:

DRDO handed over the Motor Bike Ambulance “Rakshita” to CRPF.
♦ Institute of Nuclear Medicine and Allied Sciences (INMAS) Rakshita was handed over to the Central Reserve Police Force by DRDO Laboratory in Delhi (CRPF).
♦ This is a bike-based emergency vehicle intended to carry the disabled.
♦ Rakshita is equipped with a custom-made reclining Casualty Evacuation Seat (CES), which can be installed and removed as required.
♦ The bike ambulances are built to help address the obstacles facing Indian security forces and emergency health care providers.
♦ It will provide life-saving support for the evacuation of low-intensity conflict areas to evacuate wounded patients.
♦ In addition to being useful for paramilitary forces and armed forces, this bike ambulance is also useful in possible civilian areas.

Large-Scale Digital Migration of Users to Messaging Platform Signal:

WhatsApp, which is operated by Facebook, recently revised its privacy policy, resulting in a huge digital shift of users from the messaging site to its rivals (such as Signal app).


♦ The Signal is a centralized secure messaging service that is cross-platform. The Signal Technology Foundation and Signal Messenger LLC are designing it.

♦ With an initial investment of US$50 million by Brian Acton, the non-profit Signal Foundation was founded in 2018.

♦ Send one-to-one messages and community messages using the Internet, which may include files, voice notes, photos and videos.

♦ It can also be used for clustered voice and video calls and for one-to-one calls.


♦ As an identifier, Signal uses a regular cell phone number and protects all communications with other users of Signal using end-to-end encryption.

AstroSat - Ultraviolet Imaging Telescope:

In the Milky Way NGC 2808, the AstroSat Ultraviolet Imaging Telescope found unusual, ultraviolet, bright stars.
♦ In the Milky Way galaxy, NGC 2808 is a globular cluster that is said to have at least five generations of stars.
♦ The old globular star cluster known as the " dinosaurs of the universe" offers an outstanding laboratory where, through the stunning ultraviolet images given by the Ultraviolet Imaging Telescope (UVIT) phase evolution, astronomers can understand how a star changes between its birth and death.
♦ Globular clusters are circular arrays of galactic core-orbiting stars. Clusters like that are closely bound by gravity.

Maiden Flight Trial of SAHAYAK-NG - Air Droppable Container:

The Defense Research and Development Organization-DRDO and the Indian Navy conducted the "SAHAYAK-NG" successful maiden test along the Goa coast. This is the first indigenous Air Dropped Container of IL 38SD aircraft designed and produced by India (Indian Navy)
♦ The IN-Indian Navy conducted the trial to develop its combat logistics capabilities and provide essential engineering warehouses for ships deployed from the coast more than 2,000 kilometres away.
♦ Reduced the need to collect spare parts and warehouses close to the coast for ships.
♦ SAHAYAK-NG is the advanced version of SAHAYAK Mk I.
♦ The newly designed airdrop GPS-assisted container can hold up to 50 kg of payload and can be dropped from a heavy aircraft.
Swasth Vayu Non-Invasive Ventilator Receives Regulator Nod:
The nod regulator award was won by the Swasth Vayu non-invasive ventilator created by CSIR-NAL. The Swasth Vayu non-invasive ventilator is an indigenously built and developed non-invasive bi-level positive airway pressure ventilator.
♦ For the care of COVID-19 patients, the ventilator often has other features.
♦ It is an accurate microcontroller-based closed-loop adaptive control system with an integrated biocompatible "3D printing manifold and coupler" and a HEPA filter (high efficiency particulate air filter).
♦ These specific characteristics help relieve the concern that the virus will spread. It has functions such as random / AUTO mode, CPAP, Bi-Timed, and can be linked from the outside to an oxygen concentrator or concentration unit.
♦ The efficiency of the equipment was assessed by an expert committee consisting of the Government of India`s Director-General of Health Services, Ministry of Health & Family Welfare.
♦ After careful evaluation, the expert committee concluded that Swasth Vayu can be used for COVID-19 patients who need supplemental 35% oxygen.
♦ The technology has been commercialised by CSIR-NAL with six private companies, one of which (belonging to the MSME category) has set up a production facility of almost 300 units per week.
A part laboratory of the Council of Science and Industrial Research (CSIR) of India, the National Aerospace Laboratory (NAL) is the only government aerospace R&D laboratory in the civil sector. CSIR-NAL is a high-tech company which is committed to advanced aerospace disciplines. Founded in 1959, NAL is based in Bangalore, Karnataka.

FSSAI Slashes Limit For Trans-Fat Levels In Foods:
FSSAI has approved food amendments to restrict the amount of trans fatty acids (TFA in fats and oils) from the current 5% to 3% in 2021 and 2% in 2022. Normal Laws (Prohibition and Restriction of Sales).
♦ Edible refined oils, vanaspati (partially hydrogenated oils), margarine, bakery shortenings and other cooking media, such as vegetable fat spreads and mixed fat spreads, are protected by revised regulations.
♦ The increased risk of heart failure and death from coronary heart disease is associated with Transfat.
♦ According to WHO (World Health Organization) data, there are approximately 540,000 deaths worldwide per year due to the intake of industrially produced trans-fatty acids.
♦ The WHO has also called for trans fats to be removed globally by 2023.
Trans – fats:
The most dangerous fat types are trans fatty acids (TFA) or trans fats. It is more detrimental to the human body compared with other food ingredients. The majority of these fats are manufactured artificially, but a small amount is created naturally. These could therefore be in our diet in the form of artificial TFA and/or natural TFA. When hydrogen reacts with oil to create, artificial TFAs are produced fat similar to pure ghee/butter. In our diet, the main source of artificial TFA is partially hydrogenated vegetable oil (PHVO)/vanaspati/margarine, while natural TFA is found in meat and dairy products, though in small amounts.
