Helicobacter pylori (H. pylori)
Indian researchers created a quick two-step test using PCR to find an H. pylori infection and detect clarithromycin-resistant bacteria in just seven hours.
- There is an increasing trend of clarithromycin-resistant H. pylori in India leading to a decreasing success rate in treatment.
- H. pylori infection is major risk factors for gastric cancer.
- In India, the infection affects 60-70% of population.
- Infection is often acquired during childhood and remains in stomach throughout life if not treated.

Project Kusha
Indian Defence Acquisition Council recently cleared the procurement of the Indian Long Range Surface Air Missile(LRSAM) system under Project Kusha.
- An ambitious defence initiative by India aimed at developing its long-range air defence system by 2028-29.

Vitrimer incorporated with polyrotaxane (VPR)
Scientists in Japan have developed a new version of plastic called VPR which is based on an epoxy resin vitrimer.
- Vitrimers are recent category of plastics known for strength at low temperatures and reshaping under heat.
- They tend to be very brittle and to overcome this, researchers added polyrotaxane to the plastic-making process which resulted in VPR.
- Properties – Stronger and stretchier; Partially biodegradable.
