Madagascan bird declared extinct

May 26, 2010 Discovery No Comments

London, England (CNN) — The Alaotra Grebe, a small diving bird native to Madagascar has been officially classified extinct, according to a leading bird conservation organization.

BirdLife International reported that the species, once found on Lake Alaotra, the largest lake in Madagascar, declined rapidly due to carnivorous fish being introduced to the lake and the use of nylon gill nets by local fishermen.

“No hope now remains for this species. It is another example of how human actions can have unforeseen consequences,” Dr Leon Bennun, BirdLife International’s director of science, policy and information said in a statement.

Invasive alien species are causing extinctions around the globe, Bennun says, and are one of the major threats not just to birds but to other wildlife.

BirdLife International’s report is the latest update to the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species for birds and highlights additional cases of the negative impact of invasive species on bird life.

The status of Zapata Rail — a blue/brown bird native to Southwest Cuba — was upgraded to “critically endangered” due to the introduction of mongoose and exotic catfish to its marshland habitat.

10 things we have learnt about Africa

April 15, 2010 Discovery No Comments

The Pew Research Center has just released one of the biggest ever studies on attitudes to religion and morality in Africa, which has revealed a host of interesting facts.

Here are 10 things we have learnt from the study, which surveyed 25,000 people in 19 countries.

1. 75% of South Africans think polygamy is “morally wrong” – bad news for their president, as Jacob Zuma took his third wife earlier this year and is engaged to a fourth. However, the survey also revealed some possible double-standards. While only 7% of Rwandans approved of polygamy (although this did include women), a rather higher number – 17% – of men said they had more than one wife.

2. An overwhelming majority of respondents disapproved of homosexual behaviour. In three countries – Zambia, Kenya and Cameroon – this was a massive 98%. Interestingly, one of the countries with the highest numbers of people – 11% – accepting homosexuals is Uganda, where an MP is trying to get legislation passed which would punish homosexual acts with life in prison and even death in some cases. The former Portuguese colonies of Guinea-Bissau and Mozambique were also relatively tolerant of homosexuality.

3. Africa is probably the world’s most religious continent, with more than 80% saying they believed in God in most countries. At least half of the Christians questioned expect Jesus Christ to return to earth during their lifetimes. In Ethiopia, 74% of Christians say they have experienced or witnessed the devil or evil spirits being driven out of a person and in Ghana, 40% of Christians say they have had a direct revelation from God.

4. Zimbabwe, where the Lemba people say they are the lost tribe of Israel, was not one of the countries surveyed. But 26% of Nigerian Christians said they traced their origins back to Israel or Palestine.

Huge head of pharaoh unearthed in Egypt

February 28, 2010 Discovery No Comments

A colossal red granite head of one of Egypt’s most famous pharaohs has been unearthed in the southern city of Luxor, officials said.

The 3,000-year-old head of Amenhotep III – grandfather of Tutankhamun – was dug out of the ruins of the pharaoh’s mortuary temple.

Experts say it is the best preserved example of the king’s face ever found.

The 2.5m (8ft) head is part of a larger statue, most of which was found several years ago.

Antiquities officials say the statue is to be reconstructed.

“Other statues have always had something broken – the tip of the nose, or the face is eroded,” said Dr Hourig Sourouzian, who has led the Egyptian-European expedition at the site.

“But here, from the top of the crown to the chin, it is so beautifully carved and polished, nothing is broken.”

Octopus snatches coconut and runs

December 14, 2009 Discovery No Comments

An octopus and its coconut-carrying antics have surprised scientists.

Underwater footage reveals that the creatures scoop up halved coconut shells before scampering away with them so they can later use them as shelters.

Writing in the journal Current Biology, the team says it is the first example of tool use in octopuses.

One of the researchers, Dr Julian Finn from Australia’s Museum Victoria, told BBC News: “I almost drowned laughing when I saw this the first time.”

He added: “I could tell it was going to do something, but I didn’t expect this – I didn’t expect it would pick up the shell and run away with it.”

Quick getaway

The veined octopuses (Amphioctopus marginatus) were filmed between 1999 and 2008 off the coasts of Northern Sulawesi and Bali in Indonesia. The bizarre behaviour was spotted on four occasions.

The eight-armed beasts used halved coconuts that had been discarded by humans and had eventually settled in the ocean.

25 years on, Bhopal still suffers from gas leak tragedy

December 2, 2009 Discovery No Comments

Bhopal, India (CNN) — T.R. Chouhan walked solemnly through the rusted remains of the Union Carbide pesticide factory in Bhopal, India. “I come here frequently,” he said. “We used to work here, and now this is the condition of the plant. So it feels really bad.”

Chouhan was a 10-year veteran employee of the plant when disaster struck 25 years ago. Shortly after midnight on December 3, 1984, a cloud of methyl isocyanate gas wafted into the Bhopal atmosphere. Outside the factory’s concrete walls, quiet neighborhoods quickly became chaotic.

“Everybody started screaming, ‘There’s a gas leak, there’s a gas leak!’ So we started running,” recalled Bhopal resident Bashiran Bi.

“When we stepped out of the house, there was no room on the streets,” remembered Hamid Qureshi, another survivor. “There was chaos everywhere. People were running in each and every direction.”

Glaciers disappearing from Kilimanjaro

Scientists say Mount Kilimanjaro's glaciers, which cap Africa's highest peak, may be gone within two decades

(CNN) — The ice and snow that cap majestic Mount Kilimanjaro in Tanzania are vanishing before our eyes.

If current conditions persist, climate change experts say, Kilimanjaro’s world-renowned glaciers, which have covered Africa’s highest peak for centuries, will be gone within the next two decades.

“In a very real sense, these glaciers are being decapitated from the surface down,” said Lonnie Thompson, professor of earth sciences at Ohio State University. Thompson is co-author of a study on Kilimanjaro published Monday in the journal Proceedings of the National Academy of Sciences.

The study’s authors blame the disappearing ice on increases in global temperatures and diminished snowfall at Kilimanjaro’s summit.

Previous studies of Kilimanjaro’s glaciers have relied on aerial photographs to measure the rate of the retreating ice. For this new survey, scientists climbed the mountain and drilled deep into the glaciers to measure the volume of the ice fields atop the 19,331-foot (5,892-meter) peak.

The ice sheet that capped Kilimanjaro in 2007 was 85 percent smaller than the one that covered its plateau in 1912, paleoclimatologists explained in the study.

The mountain’s ice cover shrank about 1 percent a year from 1912 to 1953, a rate that has accelerated in recent years. From 1989 to 2007, that rate jumped to 2.5 percent a year. Since 2000, the plateau’s three remaining ice fields have shrunk by 26 percent, scientists found.

‘Lipstick Killer’ behind bars since 1946

October 24, 2009 Discovery No Comments

Dixon, Illinois (CNN) — William Heirens, the “Lipstick Killer,” is believed to be the longest-serving inmate in the United States. He turns 81 on November 15.

Diabetes has ravaged his body, but his mind is sharp.

“Bill’s never allowed himself to be institutionalized,” said Dolores Kennedy, his long-time friend and advocate. “He’s kept himself focused on the positives.”

The days are spent mostly watching television and reading magazines. Using a wheelchair and sharing a cell with a roommate in the health unit of Dixon Correctional Center, he still yearns for a chance at freedom. It is something he has not tasted since 1946.

Heirens has been locked behind bars and walls for 63 years, making inmate C06103 the longest-serving prisoner in Illinois history, state officials say.

Study: States can’t afford death penalty

October 20, 2009 Discovery No Comments

WASHINGTON (CNN) — At 678, California has the nation’s largest death row population, yet the state has not executed anyone in four years.

But it spends more than $130 million a year on its capital punishment system — housing and prosecuting inmates and coping with an appellate system that has kept some convicted killers waiting for an execution date since the late 1970s.

This is according to a new report that concludes that states are wasting millions on an inefficient death penalty system, diverting scarce funds from other anti-crime and law enforcement programs.

“Thirty-five states still retain the death penalty, but fewer and fewer executions are taking place every year,” said Richard Dieter, executive director of the Death Penalty Information Center. “But the overall death row population has remained relatively steady. At a time of budget shortfalls nationwide, the death penalty is turning into an expensive form of life without parole.”

His group commissioned the study released Tuesday.

A privately conducted poll of 500 police chiefs released with the report found the death penalty ranked last among their priorities for reducing violent crime. Only 1 percent found it to the best way to achieve that goal. Adding police officers ranked first.

Odd facts about Nobel Prize winners

October 9, 2009 Discovery No Comments

It’s Nobel Prize announcement week, and if you had Carol W. Greider, Elizabeth Blackburn, or Jack Szostak in your office pool, you’re off to a good start (the trio will share this year’s Nobel Prize in Medicine). As we await news of the rest of the winners, here are some stories about past Nobel laureates.

1. Robert Lucas, winner of the 1995 Nobel Prize in Economics for his work on the theory of “rational expectations,” split his $1 million prize with his ex-wife.

If there were a Nobel Prize for Foresight or Timing, she should be nominated, based on a clause in their divorce settlement from seven years earlier: “Wife shall receive 50 percent of any Nobel Prize.” The clause expired on October 31, 1995. Had Lucas won any year after, he would have kept the whole million.

2. Physicist Lise Meitner, whose work helped lead to the discovery of nuclear fission, was reportedly nominated for the Nobel Prize 13 times without ever winning (though nominations are kept secret, so we don’t know for sure). This makes her the Dynasty of the Nobel Prize scene — that show was nominated for 24 Emmy Awards but never won. Other analogies we’d accept: The Color Purple (11 Oscar nominations in 1985, no wins), the Buffalo Bills or Minnesota Vikings (4 Super Bowl losses each without a victory) and William Jennings Bryan (three-time Democratic nominee for President, losing twice to McKinley and once to Taft.)

Report: More than 1M preemies die in first month annually

October 4, 2009 Discovery No Comments

(CNN) — More than 1 million babies born prematurely die each year before they are a month old, the March of Dimes said Sunday in the first comprehensive global report on premature births.

The organization suggested the situation could worsen if the rate of premature births increases.

Each year, 12.9 million infants — or nearly 10 percent of the annual worldwide birth total — are born before 37 weeks of development in the womb, the organization said. More than 85 percent of the premature births occur in developing countries in Africa and Asia.

“Premature births are an enormous global problem that is exacting a huge toll emotionally, physically and financially on families, medical systems and economies,” March of Dimes President Jennifer Howse said in a statement. “In the United States alone, the annual cost of caring for preterm babies and their associated health problems tops $26 billion.”

The March of Dimes report, which used data collected by the World Health Organization, breaks down premature birth rates by continent.
