Researchers zero in on potential new function of lymphatic system: producing blood

Scientists made a groundbreaking discovery that lymphatic vessels can produce both red and white blood cells, challenging the long-held belief that blood cells come solely from bone marrow. The study suggests that lymphatic vessels may play a role in fighting infection and could be important for treating certain blood cancers.

Fertility treatment does not adversely affect cardiovascular health of offspring, international study suggests

A large international study found no robust difference in blood pressure, heart rate, lipids, and glucose measurements between children conceived naturally and those conceived using assisted reproductive technologies. Children conceived via ART had slightly higher cholesterol levels in childhood, which did not persist to adulthood.

Probably not for sex

Scientists at the Smithsonian Tropical Research Institute found that matador bugs wave their legs to signal aggression or to advertise their toxicity to predators, not for sexual attraction. The study revealed no differences in waving behavior between males and females.
