The Parachute

The parachute was conceived by the 14th century, but practical demonstrations began only in the 1780s in France. The first successful parachute descent from a great height occurred in 1797, when André-Jacques Garnerin made a 3,200-ft (1,000-m) exhibition jump from a balloon. In 1802, he made an 8,000-ft (2,400-m) jump. Early parachutes were made of canvas, but this was later replaced by silk and then nylon and Kevlar. What is the world record for the highest parachute jump and longest free-fall? More...

Sts. Peter and Paul Day (2016)

It is said that St. Peter and St. Paul were both martyred on June 29, and, for this reason, their names have been linked in various observances around the world. In Peru, the Día de San Pedro y San Pablo is celebrated in fishing villages because St. Peter is the patron saint of fishermen.

HIV Drugs Tied to Early Aging

A class of antiretroviral drugs used to treat HIV, nucleoside analog reverse-transcriptase inhibitors (NRTIs), has been found to speed the accumulation of errors in mitochondrial DNA and increase the risk of age-related illnesses such as heart disease and dementia. Newer drug cocktails are less likely to cause this sort of damage, but they also tend to be more expensive. So, in poorer countries, NRTIs are still widely used. Researchers are now investigating ways to repair or slow the damage caused by these drugs. More...
