Why did Australian colonies develop? Well you can be pretty sure it was for one of two main reasons – eitheras a gaol for convicts, or because of the land, to graze sheep or cattle. Three of the states were started as gaols – New South Wales, where the First Fleet arrived; Queensla...
Anybody who has ever watched a documentary on nesting seabirds might wonder: how do parents relocate their chicks amidst the incessant din of dense breeding colonies? This touches on the more general question of how communication works against a background of noise. Mathevon describes how biologists...
Most of the evidence of Earth’s oldest life has focused on metamorphosed sedimentary structures built by sea creatures about 3.5 billion years ago. Those structures areStromatolites,matted humps of sediment trapped in layers by colonies of cyanobacterial microbes. The microbial fossils appear as disti...
also derives from its territorial sovereignty.Footnote69In the 1960s, sovereignty became “the only game in town,” at least normatively, as empires and colonies lost their legitimacy.Footnote70In a system where states recognize each others’ sovereign authority over territory...
gene transfer. Many mobile genetic elements carry a variety of genes that confer resistance to antibiotics as well as genes for autonomous DNA transfer and, thus,S. suiscan rapidly acquire multiresistance. In addition,S. suisforms microcolonies on host tissues, which are associations of ...
If grown on a large-enough scale, plants could hugely impact how spacecraft and colonies are designed. Back here on Earth, the impact of space farming will expand our knowledge of agriculture. Researchers hope to transfer what they learn about growing food in the inhospitable climate of space ...
The ammonia is rich in nitrogen, and the sugar from the soda will help feed the bacteria and grow the colonies. If that sounds too messy, then let me show you some products I depend on. Frequently Asked Questions (FAQ) What can I use as compost starter? You can use a variety of...
(passports, birth certificates) in one place.And pack a go-bag. What you pack will depend on the biggest threats in your area -- a go-bag looks different if you're packing it in earthquake-prone San Francisco or for a bushfire-prone house in Australian bush. But having everything in ...
bodies. So, had it not been for the protective influence of the GMF, Earth’s oxidising atmosphere could not have emerged and persisted. The examples of Venus and Mars show what happens to the atmospheres of planets which did not develop their inner magnetic fields or lost them earlier on....
we highlight how studies of animal swarm intelligence can inform research on collective intelligence in human teams. By improving the ability to obtain precise, time-varying measurements of team behaviors and outcomes and building upon approaches used in studies of swarm intelligence to analyze and mo...
