Cow may be biggest mammal if humans keep up extinctions: Study

Oslo, May 12: The spread of humans around the world from Africa thousands of years ago wiped out big mammals in a shrinking trend that could make the cow the biggest mammal on Earth in a few centuries` time, a scientific study said on Thursday.

The spread of hominims - early humans and relatives such as Neanderthals - from Africa coincided with the extinction of mammals such as the mammoths, sabre-toothed tiger and glyptodon, an armadillo-like creature the size of a car.

"There is a very clear pattern of size-biased extinction that follows the migration of hominims out of Africa," lead author Felisa Smith of the University of New Mexico told Reuters of the study published in the journal Science.

Humans apparently targeted big species for meat, while smaller creatures such as rodents escaped, according to the report examining trends over 125,000 years.

In North America, for instance, the mean body mass of land-based mammals has shrunk to 7.6 kg (17 lbs) from 98.0 after humans arrived.

If the trend continues "the largest mammal on Earth in a few hundred years may well be a domestic cow at about 900 kg" (2,000 lbs), the U.S. team wrote.

That would mean the loss of creatures including elephants, giraffes and hippos. In March, the world`s last male northern white rhino died in Kenya.

But other research casts doubt on a continued shrinking of mammals, partly because of conservation efforts to stave off threats to wildlife such as climate change, loss of forest habitats and pollution and expanding cities.

Thomas Brooks, chief scientist of the International Union for Conservation of Nature (IUCN) who was not involved in the study, said the projection of ever smaller mammals was "doom and gloom."

"Happily I don`t think it`s very likely," he told Reuters, saying that other research suggests that large animals such as elephants are more likely to benefit in protected areas than smaller ones.

And a Red List of threatened species, maintained by the IUCN, also lists some wild mammals roughly the size of a cow - such as the African buffalo or the brown bear - as unendangered.

The Science study also excludes marine mammals such as the blue whale, the largest creature that has ever existed. It is endangered on the Red List but the populations are rising after a moratorium on hunts.

Smith said that "my optimist hat would like to say that it`s not going to happen because we love elephants`." But she said populations of large land mammals were falling and "declining population is the trajectory to extinction."

Dubai, Jan 8: A Ukrainian airliner crashed soon after taking off from Tehran's Imam Khomeini airport on Wednesday, killing all 176 people aboard, Iran's state television and Ukraine's leaders said.

The Boeing 737 belonging to Ukraine International Airlines crashed near the airport and burst into flames. Ukraine's embassy in Iran, citing preliminary information, said the plane had suffered engine failure and the crash was not caused by "terrorism".

Ukraine President Volodymyr Zelenskiy said there were no survivors.

"My sincere condolences to the relatives and friends of all passengers and crew," Zelenskiy said in a statement, adding that Ukraine was seeking to establish the circumstances of the crash and the death toll.

Iranian TV said the crash was due to technical problems but did not elaborate. State broadcaster IRIB said on its website that one of the plane's two black boxes - the flight data recorder and the cockpit voice recorder - had been found.

Iranian media quoted an Iranian aviation official as saying the pilot of the airliner did not declare an emergency.

There was no official word from Ukraine International Airlines. It was the Kiev-based airline's first fatal crash.

"The fire is so heavy that we cannot (do) any rescue... we have 22 ambulances, four bus ambulances and a helicopter at the site," Pirhossein Koulivand, head of Iran's emergency services, told Iranian state television.

Ukraine's prime minister and Iranian state TV said 167 passengers and 9 crew were on board. Iranian TV said 32 of those on board were foreigners.

Television footage showed debris and smouldering engine parts strewn across a field, and rescue workers with face masks retrieving bodies of the victims.

According to air tracking service FlightRadar24, the plane that crashed was Flight PS 752 and was flying to Kiev. The plane was three years old and was a Boeing 737-800NG, it said.

The model's twin engines are made by CFM International, a U.S.-French venture co-owned by General Electric and France's Safran.

Modern aircraft are designed and certified to cope with an engine failure shortly after take-off and to fly for extended periods on one engine. However, an uncontained engine failure releasing shrapnel can cause damage to other aircraft systems.

A spokesman for Boeing said the company was aware of media reports of a plane crash in Iran and was gathering more information. The plane manufacturer grounded its 737 MAX fleet in March after two crashes that killed 346 people.

The 737-800 is one of the world's most-flown models with a good safety record and which does not have the software feature implicated in crashes of the 737 MAX.

Under international rules overseen by the United Nations, Iran is responsible for leading the crash investigation.

Ukraine would be involved and the United States would usually be accredited as the country where the Boeing jet was designed and built. France, where the engine maker CFM has half its activities, may also be involved.

There was no immediate word on whether the U.S. National Transportation Safety Board would be involved in the probe amid escalating tensions between the U.S. and Iran. The NTSB usually invites Boeing to give technical advice in such investigations.

Beijing, Feb 3: The first batch of patients arrived on Monday at a specialised hospital built in just 10 days as part of China's intensive efforts to fight a new virus.

Huoshenshan Hospital and a second facility with 1,500 beds that's due to open this week were built by construction crews who are working around the clock in Wuhan, the city in central China where the outbreak was first detected in December.

The Wuhan treatment centres mark the second time Chinese leaders have responded to a new disease by building specialised hospitals almost overnight. As severe acute respiratory syndrome, or SARS, spread in 2003, a facility in Beijing for patients with that viral disease was constructed in a week.

The first batch of patients arrived at the Huoshenshan Hospital at 10 am on Monday, according to state media. The reports gave no details of the patients' identities or conditions.

The ruling Communist Party's military wing, the People's Liberation Army, sent 1,400 doctors, nurses and other personnel to staff the Wuhan hospital, the official Xinhua News Agency said. The government said earlier some have experience fighting SARS and other outbreaks.

Authorities have cut most road, rail and air access to Wuhan and surrounding cities, isolating some 50 million people, in efforts to contain the viral outbreak that has sickened more than 17,000 and killed more than 360 people.

The Huoshenshan Hospital was built by a 7,000-member crew of carpenters, plumbers, electricians and other specialists, according to the Xinhua News Agency.               Photos in state media showed workers in winter clothing, safety helmets and the surgical-style masks worn by millions of Chinese in an attempt to avoid contracting the virus.

About half of the two-storey, 600,000-square-foot building is isolation wards, according to the government newspaper Yangtze Daily. It has 30 intensive care units.

Doctors can talk with outside experts over a video system that links them to Beijing's PLA General Hospital, according to the Yangtze Daily. It said the system was installed in less than 12 hours by a 20-member "commando team" from Wuhan Telecom Ltd.

The building has specialised ventilation systems and double-sided cabinets that connect patient rooms to hallways and allow hospital staff to deliver supplies without entering the rooms.

The hospital received a donation of "medical robots" from a Chinese company for use in delivering medicines and carrying test samples, according to the Shanghai newspaper The Paper.

In other cities, the government has designated hospitals to handle cases of the new virus.

In Beijing, the Xiaotangshan Hospital built in 2003 for SARS is being renovated by construction workers. The government has yet to say whether it might be used for patients with the new disease.

New Delhi, Feb 13: Arvind Kejriwal wrote to Delhi Lieutenant Governor Anil Baijal on Wednesday, staking claim to form the government in the national capital, sources said, while hinting that the AAP might not invite senior leaders and chief ministers of other parties for the oath-taking ceremony.

The sources said it was the formal process by the AAP chief, who was elected as the legislature party leader earlier in the day, to stake claim for forming the new government.

Kejriwal, who returned to power in Delhi with a stunning poll victory on Tuesday, will take oath as chief minister for the third consecutive time on February 16.

While the oath-taking ceremony will be open to the public, the Aam Aadmi Party (AAP) was considering not inviting leaders and chief ministers of other parties as it did not wish to be seen as a "confrontationist" against the BJP-led Centre, the sources said.

They, however, added that the party was yet to take a decision on it.

The AAP has planned mobilisation of people for the mega event and all the newly-elected MLAs of the party have been asked to ensure huge participation from their constituencies.

"I request the people of Delhi to attend the oath-taking ceremony of the chief minister at the Ramlila Maidan in large numbers," senior AAP leader Manish Sisodia told reporters, adding that the ceremony will start at 10 am.

The AAP won 62 seats in the 70-member Delhi Assembly, while the Bharatiya Janata Party (BJP) bagged the remaining eight seats. The Congress drew a blank for the second consecutive time in the Delhi polls.
