US businessman gets 15 years in Dubai fraud case

DUBAI, United Arab Emirates (AP) ? A Dubai court has convicted an American businessman for fraud and sentenced him to 15 years' imprisonment after a nearly five-year legal battle that included a hunger strike and a failed attempt to flee.

The case against Lebanese-born Zack Shahin also brought diplomatic tensions between the United Arab Emirates and the Unites States, which backed Shahin's demand for a trial after years in detention.

Washington did not immediately comment on Monday's sentencing, which also includes fines totaling more than $7.8 million for Shahin and three others.

The Dubai criminal court found Shahin guilty of taking nearly $5.5 million in bribes as head of Dubai-based Deyaar Development. He denied wrongdoing.

Shahin staged a hunger strike before being granted bail in July 2012. He escaped to Yemen, but was returned to Dubai.

Uncovering Africa's oldest known penguins

Mar. 26, 2013 ? Africa isn't the kind of place you might expect to find penguins. But one species lives along Africa's southern coast today, and newly found fossils confirm that as many as four penguin species coexisted on the continent in the past. Exactly why African penguin diversity plummeted to the one species that lives there today is still a mystery, but changing sea levels may be to blame, the researchers say.

The fossil findings, described in the March 26 issue of the Zoological Journal of the Linnean Society, represent the oldest evidence of these iconic tuxedo-clad seabirds in Africa, predating previously described fossils by 5 to 7 million years.

Co-authors Daniel Thomas of the National Museum of Natural History and Dan Ksepka of the National Evolutionary Synthesis Center happened upon the 10-12 million year old specimens in late 2010, while sifting through rock and sediment excavated from an industrial steel plant near Cape Town, South Africa.

Jumbled together with shark teeth and other fossils were 17 bone fragments that the researchers recognized as pieces of backbones, breastbones, wings and legs from several extinct species of penguins.

Based on their bones, these species spanned nearly the full size spectrum for penguins living today, ranging from a runty pint-sized penguin that stood just about a foot tall (0.3 m), to a towering species closer to three feet (0.9 m).

Only one penguin species lives in Africa today -- the black-footed penguin, or Spheniscus demersus, also known as the jackass penguin for its loud donkey-like braying call. Exactly when penguin diversity in Africa started to plummet, and why, is still unclear.

Gaps in the fossil record make it difficult to determine whether the extinctions were sudden or gradual. "[Because we have fossils from only two time periods,] it's like seeing two frames of a movie," said co-author Daniel Ksepka. "We have a frame at five million years ago, and a frame at 10-12 million years ago, but there's missing footage in between."

Humans probably aren't to blame, the researchers say, because by the time early modern humans arrived in South Africa, all but one of the continent's penguins had already died out.

A more likely possibility is that rising and falling sea levels did them in by wiping out safe nesting sites.

Although penguins spend most of their lives swimming in the ocean, they rely on offshore islands near the coast to build their nests and raise their young. Land surface reconstructions suggest that five million years ago -- when at least four penguin species still called Africa home -- sea level on the South African coast was as much as 90 meters higher than it is today, swamping low-lying areas and turning the region into a network of islands. More islands meant more beaches where penguins could breed while staying safe from mainland predators.

But sea levels in the region are lower today. Once-isolated islands have been reconnected to the continent by newly exposed land bridges, which may have wiped out beach nesting sites and provided access to predators.

Although humans didn't do previous penguins in Africa in, we'll play a key role in shaping the fate of the one species that remains, the researchers add.

Numbers of black-footed penguins have declined by 80% in the last 50 years, and in 2010 the species was classified as endangered. The drop is largely due to oil spills and overfishing of sardines and anchovies -- the black-footed penguin's favorite food.

"There's only one species left today, and it's up to us to keep it safe," Thomas said.

Sequencing tracks animal-to-human transmission of bacterial pathogens

Mar. 22, 2013 ? Researchers have used whole genome sequencing to reveal if drug-resistant bacteria are transmitted from animals to humans in two disease outbreaks that occurred on different farms in Denmark. The results, which are published today in EMBO Molecular Medicine, confirm animal-to-human transmission of methicillin-resistant Staphylococcus aureus (MRSA), a disease-causing bacterium that carries the recently described mecC gene. The mecC gene is responsible for resistance to the penicillin-like antibiotic methicillin.

Drug-resistant bacterial infections pose a significant challenge to public health and may have severe and sometimes fatal consequences. As the costs of whole genome sequencing methods continue to plummet and the speed of analysis increases, it becomes increasingly attractive for scientists to use whole genome sequencing to answer disease-related questions.

"We used whole genome sequencing to see if we could determine if the two disease outbreaks were caused by the same bacterium and to investigate if the pathogens were transmitted from animal to humans or the other way around," remarked Mark Holmes, from the University of Cambridge and the senior author on the paper. "At first glance, it seems reasonable to expect the same pathogen to be the source of the two outbreaks at the two geographically close locations. By looking at the single differences in nucleotides or SNPs in the DNA sequences of each isolate, it became obvious that two different strains of bacteria were responsible for the two disease outbreaks. In one case, the results also clearly showed that the most likely direction of transmission was from animal to human."

Methicillin-resistant S. aureus can lead to debilitating skin and soft tissue infections, bacteremia, pneumonia and endocarditis. The researchers used an Illumina HiSeq sequencing system to take a close look at the nucleotide sequence of each pathogen. By comparing single difference in nucleotides in the two sequences (single nucleotide polymorphisms) they were able to reach conclusions about the identity of the pathogens and the routes of infection.

The researchers emphasize that while whole genome sequencing cannot replace other more traditional types of diseases analysis it can greatly increase the ability of scientists to distinguish between different pathogens as the cause of disease.

"Our findings demonstrate that the MRSA strains we studied are capable of transmission between animals and humans, which highlights the role of livestock as a potential reservoir of antibiotic-resistant bacteria," remarked Ewan Harrison, one of the lead authors of the study.

Delhi braces for return of some serious monkey business

The Indian capital had eased its rhesus monkey problems with the help of bigger langur monkeys. Now an animal rights activist argues the solution is illegal.

By Shaikh Azizur Rahman,?Correspondent / March 21, 2013

Badal Kalandar brings his langur monkey, Pawan, to work every day on a one-hour bicycle commute in New Delhi, April 2011. Pawan hops on the back seat readily and is not afraid of the traffic in the city. Mr. Kalandar has trained Pawan to scare away smaller monkeys at the home of his employer, India's Minister of Power. Many monkey trainers are hired to prevent monkey infestations in India's government buildings.

Monkeys are poised to take back the corridors of power in the world's largest democracy.?Once literally overrun with?packs of small but troublesome rhesus monkeys, Delhi's government zone began to fight back the menace a decade ago with large langur monkeys who were?trained to them chase away.?

Now, an animal rights activist is putting a stop to the hiring of langurs and their handlers, leaving residents of the capital poised for a return of the monkey business from years past: Packs of monkeys had broken into the parliament, invaded the prime minister's office and defense ministry, at times ripping up wiring and tearing through files. Those who resisted them sometimes got bitten ? or worse.?In 2007, one deputy mayor in Delhi died after falling from his terrace while fighting off a rhesus attack.

The arrival of the black-faced langurs brought the red-bottomed?rhesus situation under control and became a normal part of life in Delhi.?

The langurs' human handlers keep them on a leash. It is commonplace on Delhi's clogged streets to see handlers bicycling to a job site with the giant monkey sitting side-saddle on a back rack. Each morning, langurs would chase the rhesus monkeys out of Parliament, then out of ministry buildings and down the streets past the living quarters of top officials. Each night, the rhesus would return, encouraged by offerings of food like bananas and peanuts left by Hindus who view monkeys as a living incarnation of the monkey god Hanuman.

So valuable were the langurs' services, that they commanded a salary higher than the vast majority of Indians.

But, now Delhi?s langur handlers have come under fire after animal rights activist and opposition politician Maneka Gandhi began protesting the practice of chaining and training the wild langurs and putting them to work.?Under the country?s Wildlife Protection Act, 1972, the langurs are a protected species and cannot be owned, traded, bought, sold, or hired out. Any violation of the law entails a three year jail term or a fine or both.

Following pressure from the activist who is also a member of Parliament, India?s Ministry of Environment and Forests issued letters to Delhi state government and several federal ministries alerting them that hiring service of the chained langurs was illegal.??

Then, last month India?s urban development ministry issued a notice to different agencies in Delhi asking them to stop using the langur guards. Fearing legal action some offices have stopped hiring the handler-langur teams to curb the rhesus menace. Some others are still using the langur guards in Delhi but are apparently in the process of ending the practice soon, said one New Delhi Municipal Corporation (NDMC) officer.

That has some in the city worried.

?The urban rhesus monkey population in Delhi is rising. So, the threats of rhesus attacks on offices are also on the rise,? says Mahaveer Singh, an NDMC officer who looks after the hiring of the langur guards by the city's civic agency. ?The trained langurs provide a very efficient service. But the pressure to stop using them is rising following the recent ban by the [urban development] ministry. I think we have to stop hiring our langur guards soon.

?But it will be very difficult to tackle the rhesus menace in the absence of these langur guards.?

Mr. Singh adds that the NDMC have 40 langur guards on its roll and the agency would be in big trouble if it faced further pressure and was finally forced to stop using them.

Some handlers say their langurs would not lose the jobs in Delhi that easily.

?All other strategies to keep the rhesus monkeys at bay in Delhi failed in the past,? says handler Mohammad Nishar.??Only our langurs can keep the parliament, courts, police stations, and other offices free from the rhesus menace. Powerful citizens are working at these places. I believe they will help amend the wildlife laws and will let our langurs continue their smart service.?

Slain ex-con is named a suspect in Colo. death

DENVER (AP) ? Colorado investigators on Saturday said for the first time that a former prison inmate who was killed in a gunfight with Texas authorities is a suspect in the death of Colorado's state prison system chief.

The evidence gathered in Texas after the death of Evan Spencer Ebel provided a "strong, strong lead" in the fatal shooting of Colorado Department of Corrections director Tom Clements, who was killed at his front door, El Paso County sheriff's spokesman Lt. Jeff Kramer said Saturday.

Kramer also confirmed Ebel had been a member of the 211s, a white supremacist prison gang in Colorado. It was not known if Ebel knew who Clements was and that he was the state's top prison official, Kramer said.

A darkly ironic connection emerged among Ebel, Clements and Colorado Gov. John Hickenlooper when the governor confirmed Friday he was a longtime friend of Ebel's father, attorney Jack Ebel.

Jack Ebel had testified before Colorado lawmakers two years ago that solitary confinement in a Colorado prison was destroying his son's psyche.

When Hickenlooper interviewed Clements for the top prison job in Colorado, he mentioned the case as an example of why the prison system needed reform, but Hickenlooper said he did not mention Ebel by name. Later, Clements eased the use of solitary confinement in Colorado and tried to make it easier for people held there to re-enter society.

Hickenlooper's spokesman said Clements did not know specifically who Ebel was.

Clements was shot Tuesday night when he answered the door of his home in a wooded, rural area north of Colorado Springs.

Kramer said investigators were trying to determine whether the 211 gang was involved in Clements' death.

The Colorado Department of Corrections was also investigating Clements' death, but spokeswoman Alison Morgan declined to say whether the 211 gang was a focus of the inquiry.

Denver police say Ebel is also a suspect in the March 17 slaying of pizza delivery man Nathan Leon. Texas authorities found a Domino's pizza delivery box and a jacket or shirt from the pizza chain in the trunk of the car Ebel was driving.

Authorities previously said that car was similar to one seen not far from Clements' home the night he was killed, and bullets Ebel fired at Texas police were the same caliber and brand as the bullet or bullets that killed Clements. But until Saturday they had stopped short of saying Ebel was a suspect.

Kramer stressed that investigators have not yet confirmed a link between Ebel and Clements' death. Tests were under way to determine if the weapon used to kill Clements was the same one recovered from Ebel in Texas.

Results could be available Monday, Kramer said.

The suspect's father, Jack Ebel, said in a statement Saturday that he was "profoundly saddened by the recent events involving my son" and asked for privacy as the family grieved, according to The Denver Post.

Ebel, who was paroled from a Colorado prison in January, was fatally shot Thursday by authorities in Texas after a pursuit reaching 100 mph.

The Tarrant County medical examiner's office in Texas said Ebel died from a gunshot wound in his forehead.

There was no indication that Hickenlooper's relationship with the Ebels played a role in the shooting. Hickenlooper said he did not having any role in Evan Ebel's parole.

Evan Ebel was paroled Jan. 28 as part of a mandatory process after serving his full prison term, Morgan said. He had most recently been sentenced to four years for punching a prison guard in 2008, according to state records.

The entire state prison system has remained under lockdown. Morgan said the lockdown would not be lifted until after a public memorial service for Clements on Sunday.
