Hairy monster: ancient 'super-armoured' worm discovered in China

Guardian Science - Mon, 2015-06-29 20:00

Collinsium ciliosum, or the Hairy Collins’ Monster, lived around 500 million years ago and is thought to be one of the first animals to develop body armour

An ancient marine worm discovered in China has been identified as the earliest known animal to have used body armour to defend itself against predators.

The creature is known as the Hairy Collins’ Monster or Collinsium ciliosum, after paleontololgist Desmond Collins, who first discovered a similar fossil in the 1980s. The Chinese specimen lived around 500 million years ago and developed “super-armour” - an array of 72 spikes along its back and sides - to protect itself from other life forms that existed at the time.

How same-sex marriage could ruin civilisation | Dean Burnett

Guardian Science - Mon, 2015-06-29 12:47

In the wake of the US supreme court ruling that legalised same-sex marriage throughout America, many commenters and objectors have claimed it will have disastrous consequences. But rather than just dismissing them as irrational bitterness, it’s important to consider the genuine scientific basis for such claims

Same-sex marriage is now legal throughout the USA. This is a good thing, it’s always nice when people get equal treatment under the law. Sadly, not everyone agrees. Such is the speed of modern news and communication that announcement of the Supreme Court decision was essentially immediately followed by furious objections and doom-laden predictions of the collapse of society for various reasons.

It’s easy to dismiss these objections as angry incoherent bitterness from people who can’t or won’t accept that the rest of the human race doesn’t have to conform to their antiquated views, and many people do just that. But what if they’re not? What if there are genuine scientific reasons to fear same-sex marriage? After all, we in the UK know that same-sex marriage caused extreme flooding when it was legalised here, and now that it’s permitted in a country with the size and influence of the USA the consequences could be even more catastrophic. Here are just some possibilities we should brace ourselves for.

The dangers of Disney’s film about Charles Darwin | Philip Ball

Guardian Science - Mon, 2015-06-29 09:00
Faced with a man so misunderstood, a ‘swashbuckling’ biopic about the naturalist could go horribly wrong. Here are a few blunders best avoided

The news that Disney is planning an “adventure film” about Charles Darwin sounds at first blush rather ominous. The idea that Darwin had “a bit of that Indiana Jones-like swashbuckling spirit in him”, as noted in the report on the Hollywood-watching website Deadline, only heightens suspicions that the mild-mannered naturalist will be seen fighting off pirates and wrestling giant iguanas on the Galápagos. But it would be unfair to write off the project – to be directed by Stephen Gaghan, who wrote the Oscar-winning screenplay for Steven Soderbergh’s Traffic – before we know anything more about it. Disney has at least shown itself now capable of producing more than sweet, passive princesses.

Green-fingered teachers: how to grow fruit and vegetables in school

Guardian Science - Mon, 2015-06-29 07:00

The joys of growing fruit and vegetables in school go beyond filling bellies, there are lots of educational benefits too

There’s nothing more satisfying than harvesting your own crops at school. As the first plums of the season ripen on trees and tiny cabbages appear between leaves, students can feast both their eyes and their bellies, on the fruits of their labour.

But there are also a wide range of educational benefits to going green, from teaching about photosynthesis and the life of a plant to seasonal poetry and creative writing, the topic can be explored in a variety of classes.

Famous baby giant armadillo found dead

Guardian Science - Mon, 2015-06-29 06:28

After two years of recording the surprising relationship between a baby giant armadillo and its mother, scientists have found the juvenile dead in the Brazilian Pantanal.

For almost two years, Alex the giant armadillo has been the most famous of his little-known and cryptic species. Born in June of 2013, photos and videos of Alex appeared across the global media, including the BBC, National Geographic and Mongabay. From Alex and his mother, Isabelle, researchers learned that giant armadillos are far more parental and familial than long believed.

Two weeks ago, researchers found Alex dead.

Starwatch: The July night sky

Britain’s night-long summer twilight begins to subside in July so that lucky starwatchers under a dark sky may be able to glimpse the Milky Way as it arches high across the E at our map times from the Scorpius-Sagittarius region in the S towards Cassiopeia and Auriga in the NNE. On the way, it flows through the familiar Summer Triangle formed by Deneb, Altair and (brightest of all) Vega.
