If ever there was a scientific study that deserved to be a children’s picture book, this was it. Scientists belly-crawled through the forests of the Ozarks, flipping stones and looking for slimy things that wriggled away from them. They learned that the forest is secretly packed with salamanders in unfathomable numbers, as many as 10 […]The post A Surfeit of Salamanders: An Imagined Picture Book appeared first on Inkfish....

While everyone (but seemingly the media) is on basically the same page with the fact that global warming is a human caused problem — and one we need to fix the effects of this change are still coming to light. Human-induced changes to Earth’s carbon cycle – for example, rising atmospheric carbon dioxide and ocean acidification – have been observed for decades. However, a new study showed human activities, in particular industrial and agricultural processes, have also had significant impa........ Read more »

Despite the established scientific consensus on global climate change, a substantial number of people, specifically Americans, deny its effects or its taking place. Why does this form of denialism persist so feverishly? What can mitigate this gap between the scientific community and the public?... Read more »

Mortality of pelagic eggs and larvae of marine fish is often assumed to be constant both in space and time due to lacking information. This may, however, be a gross oversimplification, as early life stages are likely to experience large variations in mortality both in time and space.

Understanding the drivers that determine the productivity of marine ecosystems is an important issue. Climate and exploitation interact in their effects, such that climate alterations may cause failure in a fishery management scheme while fisheries may disrupt the ability of a population to withstand, or adjust to, climate changes.

If you were assigned to watch a dozen dwarf mongooses on the savannah, would you know how to keep them safe?

What—just because they’re called gut microbes, you’ve been keeping them in your colon? How unoriginal. This is Bankia setacea, also called the Northwest or feathery shipworm.

Almost all cultures have some kind of supernatural beliefs. But it may surprise you to know that belief in moralising supernatural beings, who care about whether mortals do good or bad, are far from universal. That’s fascinating, and it begs the question: “why?”. Why do some cultures bother to believe spirits who watch over us [Read More...]

Global warming, nothing new with that and it’s here to stay for now. But while computer models churn out bleak forecasts for the planet’s future, we also have a more conceptual understanding of what is happening as humans pump carbon dioxide into the air.

There has been a lot of talk about the microbiome and Clostridium difficile infections. This is because patient antibiotic or chemotherapeutic exposure (both of which can destroy your commensal bacterial communities) increases the risk of C. difficile infection. This observation suggests a role for commensal bacteria in mediating infection resistance. The exact commensal bacteria that mediate protection against C. difficile infection are not known, but luckily for us, scientists are working o........ Read more »

While the world waits for a better battery (and a energy grid system that doesn't require constant power making), scientists are hard at work trying to teach old fuels a new trick.
