From a serene view of planet Earth, through the heart of the Milky Way and out to far-flung galaxies, take an armchair tour of the Universe with these dazzling images
Fossil fuel derived carbon dioxide has a serious impact on global climate but also a disturbing effect on the oceans, know as the other CO2 problem. When CO2 dissolves in seawater it forms carbonic acid and results in a drop in pH, the oceans acidify. A wealth of short-term experiments has shown that calcifying organisms,…
Fossil foot hints that tree-dwellers lived alongside species built for walking.
Researchers believe they have identified why a mutation in a particular gene can lead to obesity. Mouse experiments suggested the body’s message to “stop eating” was blocked if the animals had the mutation. The study, published in Nature Medicine, said the brain’s response to appetite hormones was being disrupted. The Georgetown University Medical Center researchers hope…
Microscopic plastic debris from washing clothes is accumulating in the marine environment and could be entering the food chain, a study has warned. Researchers traced the “microplastic” back to synthetic clothes, which released up to 1,900 tiny fibres per garment every time they were washed. Earlier research showed plastic smaller than 1mm were being eaten…
For fifteen years, science writer Margaret Wertheim has been collecting alternative theories of the universe. Some are poems, others include hand-drawn diagrams, and a few, at first glance, look like academic papers written by professional physicists. They have been sent to her from all over the world by people desperate to share insights about our…
You can separate out the context of discovery from the context of justification, but anyone who studies real science will see that it is deeply cultural impregnated.
