Why do bats have such bizarrely long lifespans? (4 minute read)
For most mammals, as the size of the mammal goes up, its metabolism slows down and its longevity increases. There are exceptions to this rule, including humans. 18 out of 19 species of mammals that live longer than humans given their body size are bats. Bats maintain the ends of their chromosomes to prevent cells from slipping into senescence while managing to keep cells from turning cancerous. They have genes that repair DNA damage and recycle damaged components, as well as genes that help stop cells from dividing. Bats don't seem to have an increase in inflammation as they age. The adaptations could be a product of bats evolving flight.

Can artificially altered clouds save the Great Barrier Reef? (11 minute read)
In March, Australian researchers conducted an experiment that involved using a mist machine to convert seawater into clouds of nano-sized droplets engineered to brighten clouds and block sunlight. The experiment was part of the $300 million Reef Restoration and Adaptation Program that aims to save the country's reefs. Geoengineering is a controversial topic amongst scientists and research has struggled to attract funding. However, the technology may be vital one day if humans are not able to stop climate change.
