Scientists document demographic, hormonal evidence for menopause in wild chimpanzees

NEW DELHI, OCTOBER 27: Scientists have documented demographic and hormonal evidence for menopause in wild chimpanzees, a discovery that they say provides fresh insights and raises questions about this rare evolutionary trait hitherto known only in humans and some species of whales. The study released on Thursday has shown that females in a community of wild chimpanzees in Uganda's Kibale National Park survive long past their ability to reproduce and experience a menopausal transition involving hormones similar to that observed in women. The researchers who analysed demographic and fertility data...

School curriculum: Scientists criticise Darwin axe decision

They argued that every child needed to know something about evolutionary theory because it was critical to matters far beyond the study of biology and was key to developing a rational worldview.

Infection after double dose offers shield against Delta, say scientists

NEW DELHI, JANUARY 27: Research by Indian scientists has suggested that people infected with omicron after full immunisation with the AstraZeneca or Pfizer-BioNTech COVID-19 vaccines have significant immune responses that protect them from Omicron and other Coronavirus variants. In lab experiments, the scientists at the National Institute of Virology (NIV), Pune, assessed the anti-viral immune responses of individuals who had received 2 doses of either vaccine and recovered from omicron infections against various Coronavirus variants. Their findings indicate that omicron infections in vaccinated people generate "significant" immune responses against not...
