Stress and lack of exercise are killing elephants, zoos warned

Animal welfare officers yesterday urged zoos to phase out keeping elephants, after two damning reports found the animals suffer serious health problems and die much younger in captivity.

Elephants born and raised in zoos live less than half as long as those living in their native Africa and Asia, despite being protected from predators and having better care, according to one of the reports.

Many of the deaths are thought to be linked to obesity, because the animals are well fed but get very little exercise in their small enclosures. Scientists also blamed high stress levels, which the animals suffer most after being transferred between zoos and being separated from their mothers.

Scientists called on zoos to introduce immediate health checks on elephants to identify obese and stressed animals.

In one study, researchers led by Ros Clubb, a wildlife scientific officer at the Royal Society for the Prevention of Cruelty to Animals, analysed records of 786 Asian and African female elephants kept in European zoos between 1960 and 2005. They then compared the lifespans of the captive animals with Asian elephants used by a logging company in Burma, and African elephants living in the Amboseli national park in Kenya.

Asian elephants born in captivity typically lived for 18.9 years, while those used as working animals in Burma survived for 41.7 years. African elephants also fared worse, living for 16.9 years in captivity and 35.9 years in the wild. When the scientists discounted African elephants killed by people in the national park, the typical lifespan reached 56 years, more than three times as long as those kept in zoos.

"You would expect captive elephants to live at least as long, if not longer, than those in the wild because they are better cared for, but that is not the case. The difference is massive," said Clubb, whose study appears in the US journal Science.

A second report, commissioned by the Department for Environment, Food and Rural Affairs, examined the welfare of 77 elephants in 13 UK zoos. It found that the animals spent 83% of their time indoors and 71 were overweight. Only 11 were able to walk normally.

"We often hear that zoos play a vital role in conserving elephants but patently this is not the case," said Rob Atkinson, head of wildlife science at the RSPCA.

"The new data shows elephants die young in Europe's zoos, and those Asian elephants born in captivity have a poor chance of survival. Surely the way forward is to encourage conservation programmes in native habitats rather than condemn elephants to a shortened and unhealthy existence in our zoos."

He added: "Elephants are having a torrid time in our zoos, judging by this overwhelming evidence, and action must be taken to alleviate their welfare problems as a matter of urgency."

Zoo enclosures for elephants are typically 60 to 100 times smaller than the smallest wild territories. African elephants can roam over 2,000 square miles, and Asian elephants 300 square miles. In captivity, researchers said, elephants are also at risk from infanticide, tuberculosis, herpes and lameness.

Oil Consumption to Drop for First Time in 25 Years

Oil_derrick

The world's population will use less oil this year than it did last year, according to a new forecast from highly-regarded International Energy Agency.

Global oil demand hasn't dropped since 1983 when the world's developed economies were struggling on the tail end of a recession. This time around, it's not just the old, big economies that are struggling. China, which has experienced the greatest boom in history, appears to be in economic trouble.

In a separate report, the World Bank said the global economy was teetering on the brink of recession. One sign of the times: here in California, home to Web 2.0, green tech and Silicon Valley, the state's tax revenues came in nearly 20 percent below expectations this month.

And biofuel companies trying to capitalize on last year's high oil prices may suffer from a crippling one-two punch: The financial crisis froze money that might have flowed into their coffers, while the precipitous decline of energy prices makes them look relatively less attractive.

That's what happened back in the mid-'80s, after all. Simpering economies and the collapse of crude oil prices in 1986 effectively tanked biofuel research for decades.

But there is a big difference between the mid-'80s and today: the president. Back then, Ronald Reagan, no fan of alternative fuels, sat in the Oval Office. This time around, Barack Obama — broadcasting his green-jobs promise — will be at the helm.

The presumed appointment of Steven Chu, a noted advocate of renewable energy and research scientist, to head the Department of Energy, could be just the ray of hope green-tech companies need in these dark times.

Well, that, and the price of oil bounced off the $40 mark and up to $48 over the last several days, even if analysts ascribed the rise to a weakening dollar and recent moves by OPEC to cut production.

MIT: Your Meteorologist Needs an Army of Drones

3uavs

Flying drones aren't just for firing rockets at unsuspecting enemies anymore.

By using swarms of sensor-laden flying robots, a team of MIT scientists says they can improve weather predictions — extending the accuracy of forecasts to as many as five days.

"If you wanted a motivation for why you need better data, all you have to do is look out the window. Predicting the weather is hard to do when we have good data. It's very hard to do when we don't have good data," said Jonathan How, an MIT aeronautical engineer. "If you can take measurements at the same time over distributed areas, you get a better idea of what the weather pattern is and how it's evolving."

As most people have surmised, weather forecasts made more than 48 hours ahead are not highly accurate. But with extreme weather events expected to increase in a changing climate, there is a new urgency to the old problem of knowing when the sun will shine. Evacuations depend on accurate forecasts, and so do beleaguered airlines.

Increasingly, flying drones are being used to gather data about the oceans and atmosphere. During last year's extreme anti-smog program in Beijing during the Olympics, one professor sent UAVs into the pollution cloud emanating from the city. Other scientists have designed robotic submarines to troll the oceans for data.

The system that How and his co-investigators envision would send teams of networked drones into the sky. As they return with new information on the various types of weather patterns, the swarm would be rapidly redeployed to get meteorologists the most relevant and interesting data.

"They would execute a flight plan and extract more information about the weather, which would be fed back to update the current models," said How.

But building the flight plan for all those drones is just about as hard as it sounds. There are millions of variables to consider and huge amounts of terrain — like, say, the Pacific Ocean — to cover. After three years of research, How thinks that his algorithm is ready to direct the flying weather stations to the best possible locations. Now all they need is the right design for the UAVs.

"We can collect data, get a better prediction and improve the [weather] models," How said.

2000-year-old Antikythera computer comes back to life


Regulars of the Science Weekly podcast will remember our interview with Jo Marchant, the author of Decoding the Heavens. The book tells the story of the Antikythera mechanism, a mysterious clockwork object made up of numerous meshed cogs that was discovered more than a century ago among the cargo of a Greek shipwreck.

The mystery of how the Greeks had made a machine that appeared to be 1800 years ahead of its time and why that knowledge was seemingly lost is fascinating, but Marchant's story is really about the scientists and engineers who have fallen under the spell of the Antikythera mechanism over the last century. It is a gripping tale of scientific obsession, rivalry and skulduggery.

If there is one thing that lets the book down, it lacks clear diagrams of how the cogs fitted together and hence how the mechanism worked. This video makes up for that. It shows Michael Wright's working model of the Antikythera mechanism. I defy you not to be amazed.

Fertility drugs may increase risk of womb cancer

Women who take fertility drugs to boost ovulation may have an increased risk of developing womb cancer in later life, a study has found.

Scientists examined the medical records of 15,000 women who gave birth 30 years ago and found that those who had taken fertility-enhancing drugs were significantly more likely to be diagnosed with womb cancer than those who did not have the treatment.

Of 567 women who were given any type of drug to boost ovulation, five developed womb cancer, about three times as many as would be expected in the general population.

The 362 women who took a fertility drug called clomiphene had a four-fold increased risk of developing womb cancer. The drug prompts the body to make more eggs by inhibiting the activity of the sex hormone oestrogen.

The team, led by Dr Ronit Calderon-Margalit at Hadassah-Hebrew University in Jerusalem, also found that fertility drugs were associated with smaller but significant increases in the risk of breast cancer, malignant skin cancer and non-Hodgkin's lymphoma.

The study appears in the American Journal of Epidemiology.

Jodie Moffat at Cancer Research UK said the study was too small to draw any firm conclusions about the drug. "This study didn't include a detailed history of fertility drug use, and the number of women who developed uterine cancer was very small," she told New Scientist magazine.

Calderon-Margalit said the findings made sense, adding that the breast cancer drug tamoxifen, which works in a similar way to clomiphene, also increases the risk of womb cancer.

A spokesman for the pharmaceutical company Sanofi-Aventis, which markets clomiphene, said: "This safety concern had already been debated by experts and so far no formal conclusion has been established."

He added that the company was "committed to evaluating any new evidence and discussing with experts and healthcare authorities the appropriate information measures".

Clomiphene is considered a first step in fertility treatment for couples who have trouble conceiving when there is no obvious medical problem. If this fails, women may receive hormone injections that trigger the ovaries to produce lots of eggs at once.
