Thinking smarter, not harder

Something the Hanrahans of this world never seem to notice – over the past century the human race has been getting smarter, at least smarter at the sort of abstract reasoning that IQ tests measure. But interestingly in the most “advanced” human societies we have – the Scandinavian ones – this progress has stopped.

So says the researcher who found this:

If we are to make any further progress, we will have to start exercising different parts of our brain, particularly the parts controlling language acquisition and empathy, according to Professor Flynn, an emeritus professor at the University of Otago in New Zealand….
The challenge for humanity now is to enhance our ability to debate moral and social questions intelligently. One way to do this might be to concentrate on reading great works of literature which expand our vocabulary, critical acumen and emotional maturity.
But the fact that, as a society, we are unwilling to make the sacrifices necessary to preserve the environment, suggests we still have a long way to go on this front, Professor Flynn said.

Is it a bird? Is it a bat?

No, it is a flying squirrel – dodging the Pterodactyli back when mammals were still young.

It has been named Volatico therium antiquus, meaning ancient gliding beast, and was so well preserved that impressions of fur and part of a skin membrane survive in the rock in which it was found.
The animal, being light and boasting large skin membranes that stretched between the limbs, was one of the most accomplished gliders known.
It is by far the earliest mammalian flier discovered and predates the earliest known bat, which is 51 million years old, by more than 70 million years. The earliest gliding rodent is 30 million years old.

The new, the old and the surprising…

Europe’s first new mammal to be discovered in 150 years is Mus cypriacus, or if you’re being familiar the Cypriot mouse. Of course people knew that they were there, but not that it was a separate species – a reminder of how little we still know about the natural world, even in the most-studied region of it.

A rather delicious little piece of historical irony – a group of Maori are claiming British pensions (which give the comparative level of the NZ dollar versus sterling would come in very handy).

The claim is based on the 1840 Treaty of Waitangi, the document that handed sovereignty over New Zealand to Britain, ruled at the time by Queen Victoria.
Article Three of the treaty guarantees Maori “the same rights and privileges as British subjects.”

You might call it the price of empire.

Then a surprising (if perhaps only temporary – due to share prices) fact out of China – the richest person there, topping the list of billionaires, is a woman.

Ms Zhang, the 49-year-old founder of Nine Dragons Paper, which buys scrap paper from the United States for use in China, shot from 36th to pole position in the annual China Rich List compiled by Hurun Report, the luxury publishing and events group, making her the first woman ever to top the Rich List.
“She is the wealthiest self-made woman in the world,” said Rupert Hoogewerf, a researcher who has been compiling the rich list for seven years. Her fortune trumps that of US chat show queen Oprah Winfrey and the Harry Potter creator J K Rowling. Her wealth was estimated at £202m last year, but the share price of Nine Dragons has tripled since she listed her company on the Hong Kong stock exchange and the market for recycled products is growing at a furious pace.
The previous incumbent, Huang Guangyu of China’s biggest electronics retailer, Gome, has been knocked into second place, with his personal wealth thought to be £1.3bn.

Nothing like a good cup of tea

Another interesting example of science “proving” the truth of “old wives’ tales” – a nice cup of tea does help to deal with stress. (In a genuine double-blind trial tested against a tea-like placebo.)

“Tea is chemically very complex, with many different ingredients such as catechins, polyphenols, flavonoids and amino acids. All have been found to have effects on neurotransmitters in the brain, but we cannot tell from this research which ones produced the differences.”
He added: “Although it does not appear to reduce the actual levels of stress we experience, tea does seem to have a greater effect in bringing stress hormone levels back to normal.
“This has important health implications, because slow recovery following acute stress has been associated with a greater risk of chronic illnesses such as coronary heart disease.”

Echinacea – this week it works

As a person who gets a cold every time I catch public transport once the weather has left dead summer (or at least it often feel like that), I had tried echinacea. But it is hard to tell wiith a case study of one whether it is working – my colds usually last two weeks and “flus” a month … so it all blurs after a while.

But after reading some apparently definitive study or another I gave up on echinacea. But it seems I’ll have to try it again:

Use of echinacea, or extract of the purple coneflower, before the onset of full-blown symptoms of the common cold reduces the incidence by more than a half and the duration by almost two full days, researchers reported here at the annual meeting of the American College of Clinical Pharmacology.

The last Neanderthal

Of course we’ve known for a long while that there must have been, somewhere in Europe, a human who died out, the last of their species, but now suddenly, with the discovery of Neanderthal materials that may date as late as 24,000 years ago (and certainly 28,000) in Gibraltar, the image of that “last of their kind” gets a lot clearer.

The last Neanderthal quite possibly was not the victim of our own rampant human species, but of climate change …

Food for thought there.
