Explanation: New data-wiping malware known as HermeticWiper has attacked hundreds of
computers in Ukraine in a series of cyber-attacks after Russia’s invasion.
In June 2017, the world witnessed most destructive malware ever deployed named NotPetya,
with Ukraine as its primary target. It quickly spread to more than 60 countries, destroying the
computer systems of thousands of multinationals.

Explanation: The Defense Research Development Organisation (DRDO) has indigenously
developed Monolithic microwave integrated circuits (MMICs), which are on board the EOS04
satellite. These circuits are used for radar imaging modules of the satellite.
The satellite was launched in February 2022 by ISRO to provide high-quality images for
applications such as forestry, agriculture etc.

Explanation: IIT Kharagpur has launched the peta-scale supercomputer PARAM Shakti
inaugurated by West Bengal governor Jagdeep Dhankhar.
PARAM Shakti was developed under the National Supercomputing Mission, a joint initiative of
the Ministry of Electronics and Information Technology and the Department of Science and
Technology. Supercomputer ‘PARAM Ganga’ was earlier installed at IIT Roorkee.

Explanation: In the recent study published by Washington State University, the researchers
have demonstrated the idea of incorporating old masks into a cement mixture to create stronger,
more durable concrete.
As per the paper, the mixture using mask materials was 47% stronger than commonly used
cement after a month of curing. Production of cement is a carbon-intensive process, responsible
for 8% of carbon emissions worldwide.

Explanation: Scientists in the US have developed a rapid Covid-19 test that can accurately
detect all current variants of SARS-CoV-2 within hours named CoVarScan.
Scientists typically use whole genome sequencing, to determine which variant of Covid-19 a
patient has been infected with and it is time-consuming and expensive.

Explanation: Union Cabinet approved the transfer of 10 in-orbit communication satellites from
the Government of India to NewSpace India Ltd (NSIL).
NSIL, the commercial wing of ISRO, is a Public Sector Enterprise under the administrative control
of the Department of Space. The Cabinet has also approved increasing the authorised share capital
of NSIL from Rs 1,000 crore to Rs 7,500 crore.

Explanation: Centre for Neuroscience (CNS), IISc reseachers have developed algorithm to
study brain activity. Using ‘Regularized, Accelerated, Linear Fascicle Evaluation, or ReAl-LiFE’
algorithm, enormous amounts of data generated from diffusion Magnetic Resonance Imaging
(dMRI) scans of the human brain can be analysed.
Using ReAL-LiFE, the team could evaluate dMRI data over 150 times faster than existing state-
of-the-art algorithms.

Explanation: Artemis III mission is the crewed Moon landing mission of the US Space agency
NASA. Under the mission, NASA has planned to send the first woman and person of colour to
the Moon. It is scheduled for launch in 2025.
NASA has recently announced 13 potential landing sites for the missions, which are in proximity
to the lunar South Pole. Each site is scientifically significant as the lunar South Pole is
unexplored by humans and it has some regions rich in resources.
