India's first hydrogen train to be flagged off on July 17
India's first hydrogen-powered train will run as a special inaugural service on July 17 on the 89-km Jind-Sonipat route in Haryana, with 12 stations and a two-hour journey; the date for regular passenger service is yet to be decided.
A hydrogen train ('hydrail') uses hydrogen fuel cells that generate electricity through a chemical reaction of hydrogen and oxygen, so the only emission is harmless water vapour — a viable alternative to diesel on non-electrified routes.
With this, India joins a small group of countries operating hydrogen trains; the 10-coach rake seats 682, has a capacity of about 2,600 and a top speed of 120 kmph.

PM praises Australia's under-16 social media ban, hints at similar curbs
At the Australia-India leaders' summit, PM Modi called Australia's move to bar children under 16 from social media 'highly inspiring' and said India was 'learning a lot'; Australia was the first country to legislate a nationwide under-16 ban covering Instagram, Facebook, X, TikTok, YouTube and Snapchat.
The IT Ministry is in talks with platforms on age-based safeguards; some states have floated their own limits (Andhra below 13, Karnataka below 16), and the government asked Instagram to remove adverts linked to child sexual abuse.
Separately, the Allahabad High Court's Lucknow bench sought responses on a PIL to restrict minors' access to online gaming platforms such as Roblox, directing bodies including the National Commission for Protection of Child Rights (a statutory body under the CPCR Act, 2005) to reply.

NGT halts games at Jaipur, Navi Mumbai, Raipur stadiums over groundwater lapses
The National Green Tribunal restrained three major cricket stadiums — DY Patil (Navi Mumbai), Sawai Mansingh (Jaipur) and Shaheed Veer Narayan Singh (Raipur) — from hosting any sports activity without its prior permission for failing to comply with directions on groundwater use.
The stadiums did not furnish required information to the Central Ground Water Authority (CGWA); the tribunal directed them to use treated sewage (STP) water for irrigation, install rainwater harvesting and comply with groundwater-conservation norms.
The NGT is a statutory body set up under the National Green Tribunal Act, 2010, with its principal bench in New Delhi; the CGWA regulates groundwater under the Environment (Protection) Act, 1986. Next hearing: August 17, 2026.

No pure petrol or lower blends as options to E20, says government
The government ruled out offering pure petrol or lower ethanol blends alongside E20, saying parallel supply chains across more than one lakh retail outlets would raise logistics costs and are not feasible; E20 has been the standard petrol variant since India achieved 20% blending in April 2025.
It argued E20 offers a higher octane rating, better anti-knock properties and cleaner engine operation, and that dedicated ethanol plants, distilleries and logistics — backed by bank loans of nearly Rs 1 lakh crore — were built to meet blending targets.
Ethanol is procured at about Rs 72 a litre (a remunerative price for farmers), making E20 costlier to produce than pure petrol; it would turn cheaper only if crude prices rose to $120-130 a barrel.

ISRO successfully tests its uprated CE20 cryogenic engine for the LVM3 rocket
ISRO carried out a successful hot test of its CE20 cryogenic engine, which powers the upper stage of the LVM3 (Launch Vehicle Mark-3) — India's heavy-lift launcher.
A cryogenic engine burns liquid hydrogen as fuel and liquid oxygen as oxidiser, stored at very low temperatures; this gives the high efficiency needed by the upper stage that injects satellites into orbit.
The CE20 was developed indigenously by ISRO's Liquid Propulsion Systems Centre; uprating its thrust supports heavier payloads and future missions such as Gaganyaan and the planned Next-Generation Launch Vehicle.

India, Kyrgyzstan open 'Manas and Mahabharata' Centre for Civilizational Studies in Bishkek
An Indian delegation visited Kyrgyzstan (4-7 July 2026) to inaugurate the International Centre for Civilizational Studies, themed 'Manas and Mahabharata', in the capital Bishkek — an exercise in civilizational diplomacy.
Manas is the epic of the Kyrgyz people (one of the world's longest epic poems), paired here with India's Mahabharata to underline shared storytelling and cultural heritage across Central and South Asia.
Kyrgyzstan is a landlocked Central Asian country and a fellow member of the Shanghai Cooperation Organisation (SCO); it does not share a land border with India.

Once-weekly insulin set to cut injections for diabetics from 365 to 52 a year
A new once-a-week insulin (insulin icodec) can reduce a patient's baseline treatment burden from about 365 injections a year to just 52, easing therapy for people with diabetes who need insulin.
Insulin is a hormone secreted by the beta cells of the pancreas that lowers blood glucose; in diabetes mellitus the body either does not produce enough insulin or cannot use it effectively.
Longer-acting formulations aim to improve adherence, though cost and the need to switch from daily shots remain practical hurdles.
