‘Green-beard’ genes could explain how altruism arose in nature

Altruism is widespread in nature. Worker honey bees devote their entire life to foraging and caring for their sister, the queen, and her offspring, but do not themselves reproduce. In widow spiders, a male allows a female fertilised by him to eat him, and thus nourish herself and her offspring. A meerkat, a mongoose found…

New method to generate virus-like particles, to help with developing antibodies against Nipah

Scientists at the Institute of Advanced Virology (IAV), Thonnakkal, Thiruvananthapuram, have developed a novel way of generating non-infectious Nipah virus-like particles (VLPs) in the laboratory, which mimic the wild type Nipah virus (NiV). This new method offers an alternate, safe and effective platform for developing neutralising antibodies against NiV in a bio safety level-2 (BSL)…
