GEMINI : New Blood Testing Technology For Cancer
Researchers have developed a new blood testing technology called GEMINI (Genome-wide Mutational Incidence for Non-Invasive Detection of Cancer) that uses genome-wide sequencing of single molecules of DNA combined with machine learning.
- This technology has the potential to enable earlier detection of lung and other cancers.
- The GEMINI test starts by collecting a blood sample from individuals at risk of cancer. From this sample, cell-free DNA (cfDNA) shed by tumours is sequenced using cost-efficient whole genome sequencing.
- cfDNA stands for “cell-free DNA.”
- It refers to small fragments of DNA that are released into the bloodstream or other bodily fluids when cells in the body die and break down.
- These fragments of DNA are not enclosed within cells, hence the term “cell-free.”
- Single molecules of DNA are analyzed for sequence alterations, providing mutation profiles across the genome.
- A machine learning model then identifies changes in cancer and non-cancer mutation frequencies, generating a score indicating the likelihood of having cancer.
- In laboratory tests, the GEMINI test, when combined with computerized tomography imaging, detected over 90% of lung cancers, including early-stage diseases.
- The test also identified altered mutation profiles in cfDNA from patients with other cancers, such as liver cancer, melanoma, and lymphoma, suggesting broader applications.

Akira : Ransomware
The Computer Emergency Response Team of India issued an alert for ransomware dubbed Akira.
- Akira Ransomware is designed to encrypt data, create a ransomware note and delete Windows Shadow Volume copies on affected devices.
- The ransomware gets its name due to its ability to modify filenames of all encrypted files by appending them with the “.akira” extension.
- Akira Ransomware is designed to close processes or shut down Windows services that may keep it from encrypting files on the affected system.
- It uses VPN services, especially when users have not enabled two-factor authentication, to trick users into downloading malicious files.
- The ransomware also terminates active Windows services using the Windows Restart Manager API, preventing any interference with the encryption process.
- It is designed to not encrypt Program Data, Recycle Bin, Boot, System Volume information, and other folders instrumental in system stability.
- It also avoids modifying Windows system files with extensions like .syn. .msl and .exe.
- Once sensitive data is stolen and encrypted, the ransomware leaves behind a note named akira_readme.txt which includes information about the attack and the link to Akira’s leak and negotiation site.
- Each victim is given a unique negotiation password to be entered into the threat actor’s Tor site.
- Unlike other ransomware operations, this negotiation site just includes a chat system that the victim can use to communicate with the ransomware gang.

TransLunar Injection (TLI) : ISRO
The Indian Space Research Organisation (ISRO) recently performed the TransLunar Injection (TLI) to slingshot Chandrayaan-3 towards the moon.
- TransLunar Injection (TLI) is a critical manoeuvre performed during space missions to send spacecraft from Earth’s orbit to a trajectory that will take them to the Moon.
- It is a key step in lunar missions, enabling spacecraft to escape Earth’s gravitational pull and travel to the Moon.
- The TLI is performed when the spacecraft is at a specific point in its orbit known as the ‘perigee’ or the closest point to Earth.
- During a TLI, the spacecraft’s propulsion system fires its engines to accelerate the spacecraft.
- The spacecraft gains enough speed to break free from Earth’s gravitational pull and embark on its journey toward the moon.
- The amount of thrust and duration of the TLI burn depends on various factors, including the spacecraft’s mass, its velocity in Earth’s orbit, and the specific mission objectives.
- Once the TLI is successfully completed, the spacecraft is put on a lunar trajectory, and it will continue its journey to the Moon without further propulsion from Earth.
- After the TLI, the spacecraft typically enters a transfer orbit, which is an elliptical path that intersects with the Moon’s orbit.
