2. Lithium-Rich Red Giant Stars: Recently, astronomers discovered a link between lithium-rich red giant stars and enhanced helium abundance, based on data from the Himalayan Chandra Telescope and archival observations.

• Key Highlights: Helium in cool stars cannot be directly observed; it is inferred through impacts on structure, evolution, and other spectral features.
• Researchers measured hydrogen abundance by comparing magnesium from atomic vs. molecular lines (Mg I vs. MgH).
• Any reduction in hydrogen abundance was translated into helium enhancement using model atmospheres with varying He/H ratios.
• Sample included 18 red giants and 2 supergiants observed using high-resolution spectra.
• Six of the twenty stars showed higher-than-normal helium abundance (He/H > 0.1).
• Of these six, five were red giants and one was a supergiant.
• Key Findings: All helium-enhanced red giants were super-lithium-rich, though not all lithium-rich giants had elevated helium.
• This establishes a new empirical correlation between photospheric helium enrichment and lithium enrichment in red giants.
• Marks the first spectroscopic measurement of photospheric helium abundance in normal and lithium-rich field giants.
• Helium-enriched, lithium-rich giants are found across the entire red giant evolutionary phase.

7. Wild Poliovirus: Recently, Germany confirmed the presence of wild poliovirus in a sewage sample from Hamburg, marking Europe’s first detection of the virus in 15 years, according to health authorities.

• About Polio: A viral disease that mainly affects children under five; around 1 in 200 infections leads to irreversible paralysis, and up to 10% of paralysed patients die.
• There are two forms of polio: Wild polio – now endemic only in Afghanistan and Pakistan, causing tens of cases annually.
• Vaccine-derived polio – rare but causes several hundred cases globally, linked to use of live oral polio vaccine.
• The strain found in Germany is genetically linked to the Afghanistan strain.
• Detection likely indicates importation of the virus, not local spread; no infections reported in Germany so far.
• Germany’s high vaccination coverage means low risk to the public.
• Many countries conduct sewage surveillance, and this detection signals the monitoring system is working well.
• Wild polio has occasionally appeared in countries previously considered virus-free, such as Malawi and Mozambique in 2022, via importation.
• Vaccine-derived polio detections in polio-free regions occur more frequently and have been reported in Europe and the U.S. in recent years.
• Protection advice: ensure full vaccination (oral or injectable), especially for children or anyone unsure of their immunisation status.
• Global eradication remains difficult; the Global Polio Eradication Initiative (GPEI) faces a 30% budget cut, complicating efforts.
• Detection reinforces the message: “polio anywhere is a risk everywhere”, underscoring the need to complete eradication efforts.
