Website generates off-the-shelf cryptocurrencies (so of course NewStatesmanCoin now exists)

It's completely useless, though. Don't bother downloading it. There's no point.

Things are very weird right now for those of us living in the future. Dogecoin - a digital cryptocurrency based on a funny picture of a shiba inu - has a market cap of more than $5m. We were promised jetpacks, we got dog-themed money.

There are so many new Bitcoin ripoffs (mostly by those hoping to make a fast buck) that it was inevitable that someone would create a site that automatically generates them. Coingen, created by a reddit user called Blue Matt, lets users customise their own cryptocurrency (taking either Bitcoin or smaller cousin Litecoin as inspiration), download a wallet, and get mining.

For this, users pay a fee of between 0.05 and 0.2 BTC (roughly £30 to £122 as of writing, going by the average trading price on Mt Gox), with fees for removing Coingen’s logo or getting access to the source code. That’s a tidy fee considering you can only tweak four numerical values for each coin, and the source code for Bitcoin is open and available for free already. Perhaps Blue Matt is taking inspiration from the California Gold Rush, where the biggest profits weren’t in looking for gold, but in selling equipment like picks and buckets to prospectors.

Very Dogecoin. Much currency. So zeitgeist.

And, because why not, we’ve created NewStatesmanCoin - you can download a wallet and start mining here. That’s its rather half-hearted logo up top (we considered replacing the Queen on a pound coin with a picture of deputy editor Helen Lewis, an effort you can enjoy here).

Don’t ask what the block halving rate is, or which mining algorithm it uses - random, now forgotten, numbers were used. We can probably assume from their names that many of the other coins created using Coingen use values that are just as arbitrary: jesuscoin, arbitrarycoin, starvingartistcoin, wethepeoplecoin, silvioberluscoin, realcoin, beercoin, and the catchily-named “wake_up_sheeples_banker_owned_federal_reserve_notes_equals_more_debt”. (There are also a lot of coins with racist names on there. Really, you’ve been warned.)

NewStatesmanCoin is just a joke, but the fact there are so many people who have created their own silly coins - and paid for the privilege - is worth noting. There are dozens of alternatives to Bitcoin, a tiny minority of which have support from any kind of community, and fewer still of which have any practical real-world purpose. While there are uses for cryptocurrencies, they're niche, and not without competition from more traditional companies or other technologies. Not for nothing are people like Gigaom's David Meyer asking what the point of Bitcoin is.

Looking over the transaction volume day-by-day since Bitcoin launched, it's clear that the value of the cryptocurrency has been faster and unlinked from its growth as a medium of exchange. Speculation is still the main drive of Bitcoin value, and the entire drive of Litecoin, Namecoin, and even Dogecoin value, and thus there's surely demand for Coingen's new coins, off-the-shelf and ready to, perhaps, become the next £xm-worth market. While Bitcoin's certainly popular, it's tempting to instead think that it may be the first iteration of a concept yet to be perfected.

You don't have to tell us it's a crappy logo.

Fanging out: why do vampire bats groom each other so often?

New research shows social grooming and food sharing are more common adaptive traits in vampire bats than other species.

A new study has shown social grooming behaviour is more prevalent in vampire bat species than their non-parasitic variants. The researchers used the species Desmodus rotundus and found that the bats spent 1.5-6.3 per cent of their time engaged in social grooming, compared with just 0.5 per cent in other species.

It's not exactly a secret that a range of animals engage in social interactions. This includes hyenas who simply greet each other to increase cooperation. However, recent studies have focussed on the use of social grooming being used by animals to maintain stable relationships.  

For example, age and body weight have been linked to the amount of social grooming given by dairy cows, and licking and head rubbing are used by lions to create bonds between individuals. Vampire bats also protect each other against bats with no social links to a group. Each roost site usually contains 8-12 female adults and their offspring, defended on the outside by an adult male.

Vampire bats not only show social grooming through the cleaning of each others' bodies, but also by sharing food through the ever-appetising regurgitation process. However, both of these behaviours are directly linked to one another.

When a pair of vampire bats are grooming each other and cleaning each other's bodies, they assess the bulging size of the abdomen. This allows them to check if their partner has eaten, and whether they need to regurgitate and share food.

Sharing food is a vital part of feeding and cooperation in vampire bats, as almost 20 per cent of bats don't find any food each night. This starts a ticking clock, as most bats can starve to death in under 72 hours.

The importance of social bonding is reflected in the anatomy of the bat. In proportion to their relatively small body size, vampire bats have a very large brain and neocortex. Previous studies have shown the size of the neocortex is linked to more complex social behaviour and bonding.

The authors of the paper conclude that social grooming acts as a way for bats to display their hunger to partners, or alternatively, that they are willing to share food, and for the need to sustain close bonds.
