Antarctica yields oldest directly dated ice and air sample
Scientists in Antarctica have identified the oldest directly dated ice and air sample, from the Allan Hills region of East Antarctica. The 6-million-year-old ice contains trapped air bubbles dated by argon isotope analysis, revealing long-term cooling patterns over millions of years. The finding, led by the Center for Oldest Ice Exploration (COLDEX) and researchers from Woods Hole Oceanographic Institution and Princeton University, complements the European Beyond EPICA–Oldest Ice project’s findings, which recovered a 2.8-kilometre ice core from Little Dome C dating back 1.2 million years. Together, these records provide rare glimpses into past atmospheric composition and climate change.
Ice sample age: about 6 million years; location: Allan Hills, East Antarctica.
Dating method: argon isotope analysis of trapped air.
Research teams: COLDEX; Woods Hole Oceanographic Institution; Princeton University.
Related work: EPICA–Oldest Ice project; Little Dome C core dating 1.2 million years.
Implication: informs understanding of long-term Antarctic climate history.
World AIDS Vaccine Day 2026 observed on 18 May to promote HIV vaccine research
World AIDS Vaccine Day 2026 was observed worldwide on 18 May, underscoring the urgent need for an effective HIV vaccine and continued research to end AIDS. The day, also known as HIV Vaccine Awareness Day, honours scientists, healthcare workers, volunteers and community organisations advancing HIV vaccine work. The observance traces back to 18 May 1997 when former United States President Bill Clinton delivered a speech at Morgan State University calling for a preventive HIV vaccine; the first official World AIDS Vaccine Day followed on 18 May 1998. Governments, researchers and civil society groups participate in awareness campaigns, education drives and fundraising to sustain global HIV vaccine development.

BIRSA 101 workshop on indigenous CRISPR gene therapy for Sickle Cell disease
The Ministry of Tribal Affairs, with CSIR and CSIR-IGIB, organized a workshop titled 'BIRSA 101' on 14 May 2026 in New Delhi under Janjatiya Garima Utsav 2026. The event highlights India’s first indigenous CRISPR-based gene therapy for Sickle Cell Disease (SCD) and supports tribal welfare. The project received about Rs 3.75 crore in financial assistance. The festival emphasizes technology as a development driver and aligns with broader tribal health and research goals, fostering genomic research and affordable healthcare interventions for tribal communities. Experts discussed privacy, ethics, and regulatory oversight in implementation.

IMD launches AI weather forecasting products for monsoon regions
The India Meteorological Department introduced two AI-based weather forecasting products aimed at monsoon regions dependent on rain-fed agriculture. The NCMRWF-developed product for Uttar Pradesh offers 1 km resolution rainfall forecasts with lead times up to 10 days, using data from rain gauges, weather stations, satellites, and Doppler radars. The IITM Pune-developed product tracks monsoon progression at district level and covers 3,196 blocks across 16 states and one Union Territory, with updates every Wednesday. Operated under the Ministry of Earth Sciences, the tools support agriculture, water resource management, and disaster planning.

Possible Dwarf Galaxy Loki Found Inside Milky Way
A May 2026 study in Monthly Notices of the Royal Astronomical Society proposes the existence of a hidden ancient dwarf galaxy named Loki within the Milky Way. The finding is based on chemical and orbital data from 20 metal-poor stars located within 2 kiloparsecs of the Sun. Loki’s stars display a mix of orbital directions, with 11 prograde and 9 retrograde orbits, and show chemical traces linked to supernovae and neutron star mergers. No signs of white dwarf activity are detected. If confirmed, Loki would add to the growing list of merger remnants shaping the Milky Way’s history of galactic evolution.
May 2026 study proposes Loki as a hidden dwarf galaxy
Based on 20 metal-poor stars within 2 kpc of the Sun
Stellar orbits: 11 prograde, 9 retrograde
Chemical traces point to past supernovae and neutron star mergers
No evidence of white dwarf activity observed
If confirmed, Loki would illuminate Milky Way’s merger history
