Russian Scientists Find Carcass of an Ancient Foal Perfectly Preserved in Siberia

The foal was discovered in the Batagaika crater, a huge 100-meter (328-foot) deep depression in the East Siberian taiga

Russian scientists have found the carcass of an ancient foal perfectly preserved in the Siberian permafrost.

The fossil discovered in the region of Yakutia has its skin, hair, hooves and tail preserved. Yakutia is also famous having wooly mammoth fossils found in the permafrost.

Scientists from Russia’s Northeast Federal University who presented the discovery Thursday said the foal is estimated to be 30,000 to 40,000 years old. They believe it was about two months old when it died.

Semyon Grigoryev, head of the Mammoth Museum in the regional capital of Yakutsk, was surprised to see the perfect state of the find. He noted it’s the best-preserved ancient foal found to date.

Old Dusty Kilogram Swapped for Something More Stable: Scientists

It has taken years of work to fine-tune the new definition to ensure the switchover will be smooth.

After years of nursing a sometimes dusty cylinder of metal in a vault outside Paris as the global reference for modern mass, scientists are updating the definition of the kilogram.

Just as the redefinition of the second in 1967 helped to ease communication across the world via technologies like GPS and the internet, experts say the change in the kilogram will be better for technology, retail and health — though it probably won’t change the price of fish much.

The kilogram has been defined since 1889 by a shiny piece of platinum-iridium held in Paris. All modern mass measurements are traceable back to it — from micrograms of pharmaceutical medicines to kilos of apples and pears and tons of steel or cement.

The problem is, the “international prototype kilogram” doesn’t always weigh the same. Even inside its three glass bell jars, it gets dusty and dirty, and is affected by the atmosphere. Sometimes, it really needs a wash.

“We live in a modern world. There are pollutants in the atmosphere that can stick to the mass,” said Ian Robinson, a specialist in the engineering, materials and electrical science department at Britain’s National Physical Laboratory.

“So when you just get it out of the vault, it’s slightly dirty. But the whole process of cleaning or handling or using the mass can change its mass. So it’s not the best way, perhaps, of defining mass.”

What’s needed is something more constant.

So, at the end of a week-long meeting in the Palace of Versailles, Paris, the world’s leading measurement aficionados at the International Bureau of Weights and Measures will vote Friday to make an “electronic kilogram” the new baseline measure of mass.

Just as the meter — once the length of a bar of platinum-iridium, also kept in Paris — is now defined by the constant speed of light in a vacuum, so a kilogram will be defined by a tiny but immutable fundamental value called the “Planck constant.”

The new definition involves an apparatus called the Kibble balance, which makes use of the constant to measure the mass of an object using a precisely measured electromagnetic force.

“In the present system, you have to relate small masses to large masses by subdivision. That’s very difficult — and the uncertainties build up very, very quickly,” Robinson said.

“One of the things this [new] technique allows us to do is to actually measure mass directly at whatever scale we like, and that’s a big step forward.”

He said it had taken years of work to fine-tune the new definition to ensure the switchover will be smooth.

But while the extra accuracy will be a boon to scientists, Robinson said that, for the average consumer buying flour or bananas, “there will be absolutely no change whatsoever.” (VOA)
