BioBits: Low-cost education kits for molecular and synthetic biology I Harvard University

Published on Aug 2, 2018
Researchers at the Wyss Institute, MIT, and Northwestern University have collaborated to create “BioBits,” a low-cost, shelf-stable educational kit to teach synthetic and molecular biology in K-12 classrooms. The kit utilizes freeze-dried cell-free reactions that eliminate the need for growing living cells in order to perform biological experiments. Different modules in the kit teach students different concepts in synthetic and molecular biology by engaging their senses, such as sight, smell, and touch, without expensive lab equipment or specialized training. With BioBits, the researchers hope to inspire a new generation of young scientists in a fun and engaging way for less than $10 per student.

Where have all our penguins gone? I The Times | Biology resources for South African teachers | Scoop.it

2 August 2018

The biggest colony of king penguins on the planet has collapsed, with nearly 90% of the population vanishing since the eighties, ecologists said. The colony was first discovered in the sixties on Île aux Cochons, also known as Pig Island, in the southern Indian Ocean, between Madagascar and Antarctica. At its peak it contained two million birds and 500,000 breeding pairs, but new satellite images have shown an empty landscape, in which 88% of the colony appears to have vanished.
