It's really not so simple as this. It's really dim under the sea ice and these divers have used strobes and floodlights to pick out subjects in a dramatic way. On that front I don't think the images required much tampering wi

For one thing, consumers favoring the convenience of supermarkets means choice gets limited to what large scale agribusiness can supply profitably. Local species and cultivars whose horticulture does not scale well, whose harvest can't

The qualities of the Saqqara boxes are entirely consistent with what we know about the mathematical and engineering sophistication of ancient Egyptians. There is nothing well-verified "not in the books" that upends the "conve

They are one of the most biodiverse habitats, if not the most diverse, home to a vast array of often spectacular species. And unlike other highly biodiverse habitats, much of this spectacle is densely represented and constantly on show. I

This is interesting to think about. As I'm sure you've considered, bacteria and other living cells exist in a state of highly regulated homeostasis. In bacteria, things like charged ion concentrations are maintained internally by

It's hard to directly compare the challenges of growing fungus vs. meat. Remember that in the case of fungi, the desired product for the food industry is usually a specialized reproductive structure (mushroom, truffle, etc.), produced

And that's exactly what we'll probably see here – 2/3 majority call for a general election. Just read the current headlines.

As things stand, Cameron will be replaced by a new Conservative leader in October who will be under pressure to call a general election more or less immediately (without the present mess we were not due another one until 2020). The Liberal

Well that's definitely not true. Many of the most potent toxins known to us are produced by living organisms – for an example, actually read the comment you replied to. You can find examples of substances that are spectacularly lethal

The tek you link starts from grain spawn. You don't need sterile conditions at all to propagate loads of mushroom species if you're already starting with a robust dikaryotic culture, especially those of wood-decay (lignicolous) sp

My reaction to the article (even the end of it) was "wow, this is far less bombastic and egotistic than Stephen's normal writing, how refreshing." There are lots of books and articles purely about Ramanujan, why not offer som

As others observed this is a common condition in plants (where repeated hybridizations can result in even higher ploidy conditions, e.g. tetraploid wheat, sexaploid sedums). But as you ask, why isn't it observed as often in animals,

Foraging for wild mushrooms is part of the ancient and rich culinary tradition of many European countries, where poisoning rates among those brought up in the tradition are very low. Yes reliably identifying a range of edible wild species t

Correctly identifying any given mushroom can be hard, requiring the right taxonomic keys (and the comprehensive ones come in multiple volumes), a microscope, various stains and reagents, and lots of training. Field mycologists have a term,

There are no simple rules like that which can reliably differentiate edible mushrooms from poisonous ones. The best way to start foraging is by learning some relatively unmistakeable edible species and only picking those.
