After seven years, judge orders release of Guantanamo prisoners

This video from the USA is called TORTURE: From Guantanamo to Chicago Interrogation Rooms.

From Reuters:

WASHINGTON, Nov 20- Five of six Algerians must be released after nearly seven years of captivity at the U.S. military prison at Guantanamo Bay in Cuba, a federal judge ruled on Thursday.

U.S. District Judge Richard Leon ruled from the bench after holding the first hearings under a landmark Supreme Court ruling in June that gave Guantanamo prisoners the legal right to challenge their continued confinement.

U.S. President-elect Barack Obama has promised to close the prison camp after he takes office in January. Meanwhile, U.S. judges in Washington are moving ahead with case-by-case reviews of detainee legal challenges.

Giant mono-cellular discoveries

This video from Texas, USA, is called Invertebrate Fossils – Lesson 16 – Part 2 of 7.

From the University of Texas at Austin in the USA:

Discovery of giant roaming deep sea protist provides new perspective on animal evolution

AUSTIN, Texas—Groove-like tracks on the ocean floor made by giant deep-sea single-celled organisms could lead to new insights into the evolutionary origin of animals, says biologist Mikhail “Misha” Matz from The University of Texas at Austin.

Matz and his colleagues recently discovered the grape-sized protists and their complex tracks on the ocean floor near the Bahamas. This is the first time a single-celled organism has been shown to make such animal-like traces.

The finding is significant, because similar fossil grooves and furrows found from the Precambrian era, as early as 1.8 billion years ago, have always been attributed to early evolving multicellular animals.

“If our giant protists were alive 600 million years ago and the track was fossilized, a paleontologist unearthing it today would without a shade of doubt attribute it to a kind of large, multicellular, bilaterally symmetrical animal,” says Matz, an assistant professor of integrative biology. “We now have to rethink the fossil record.”

The team’s discovery was published online today in Current Biology and will appear in a subsequent print issue.

Most animals, from humans to insects, are bilaterally symmetrical, meaning that they can be roughly divided into halves that are mirror images.

The bilateral animals, or “Bilateria,” appeared in the fossil record in the early Cambrian about 542 million years ago, quickly diversifying into all of the major animal groups, or phyla, still alive today. This rapid diversification, known as the Cambrian explosion, puzzled Charles Darwin and remains one of the biggest questions in animal evolution to this day.

Very few fossils exist of organisms that could be the Precambrian ancestors of bilateral animals, and even those are highly controversial. Fossil traces are the most accepted evidence of the existence of these proto-animals.

“We used to think that it takes bilateral symmetry to move in one direction across the seafloor and thereby leave a track,” explains Matz. “You have to have a belly and a backside and a front and back end. Now, we show that protists can leave traces of comparable complexity and with a very similar profile.”

“I personally think now that the whole Precambrian may have been exclusively the reign of protists,” says Matz. “Our observations open up this possible way of interpreting the Precambrian fossil record.”

He says the appearance of all the animal body plans during the Cambrian explosion might not just be an artifact of the fossil record. There are likely other mechanisms that explain the burst-like origin of diverse multicellular life forms.

DNA analysis confirmed that the giant protist found by Matz and his colleagues in the Bahamas is Gromia sphaerica, a species previously known only from the Arabian Sea.

They did not observe the giant protists in action, and Matz says they likely move very slowly. The sediments on the ocean floor at their particular location are very stable and there is no current—perfect conditions for the preservation of tracks.

Matz says the protists probably move by sending leg-like extensions, called pseudopodia, out of their cells in all directions. The pseudopodia then grab onto mud in one direction and the organism rolls that way, leaving a track.

He aims to return to the location in the future to observe their movement and investigate other tracks in the area.

Matz says the giant protists’ bubble-like body design is probably one of the planet’s oldest macroscopic body designs, which may have existed for 1.8 billion years.

“Our guys may be the ultimate living fossils of the macroscopic world,” he says.

British police in missionary child abuse scandal in Albania

Dino Christodoulou, one of three Britons on trial in the orphanage scandal From British daily The Guardian:

UK police withheld details of sex abuse at orphanage from Albanian authorities

• Tirana court jails British charity worker for 20 years
• Two more Britons still on trial over allegations

* Paul Lewis in Tirana
* Thursday November 20 2008

British police helped cover up a horrific sex abuse scandal at a Christian missionary orphanage in Albania, a Guardian investigation has found.

Senior officers agreed to keep details of abuse secret from their counterparts in Albania after the British director of the orphanage, David Brown, persuaded them that while children had been sexually abused in his care, he had played no part in it.

Brown, 57, an evangelical charity worker who founded the His Children orphanage seven years ago, was yesterday found guilty of “sexual relations” with minors. …

Ten children, aged between four and 13, told Albanian police they had been sexually abused by Brown and the two Britons. In some cases the children claim to have been bound to a balcony, gagged and raped.

But an investigation has revealed that Britain’s National Criminal Intelligence Service (NCIS) received details about abuse at the home 18 months earlier, in December 2004, and failed to tell their Albanian counterparts. …

There were no attempts to rescue the Gypsy [mainly Muslim in Albania] children at the orphanage, where Brown slept with boys in his bed.

“A lot of us were uncomfortable about what was going on in there,” said a pastor who agreed not to inform Albanian police about the shelter. ” But we believed David was a good man. And we didn’t want all the good work our churches were doing to be associated with David’s orphanage.” …

Brown described [his associates] Christodoulou and Arnold, whom he blamed for the abuse, as “wolves in sheep’s clothing”. He described his trial as “my day on the cross”. “I am the father of these children and I have a duty under God to defend them,” he said.

Apparently, there also is a For His Children Orphanage, with United States connections, in Quito, Ecuador. I do not know whether there is any connection to “Mr” Brown’s organization in Albania, or that just the names happen to be similar.
