Newly Detected Objects Draw Searchers for Malaysian Plane 

By MICHELLE INNIS and CHRIS BUCKLEYMARCH 20, 2014

The New York Times 

SYDNEY, Australia — Satellite cameras spotted objects floating in the southern Indian Ocean that might be parts of the Malaysia Airlines jet that vanished on March 8, the Australian prime minister, Tony Abbott, said on Thursday. 

Mr. Abbott and an Australian rescue organizer both counseled caution about the sighting, found in images recorded on Tuesday. The first Royal Australian Air Force plane to fly over the estimated location of the objects returned to base Thursday without spotting anything that fit the description – a reminder of how the hunt for the missing Boeing 777 jetliner could remain long, difficult and possibly fruitless. 

The Australian Maritime Safety Authority said in a message on Twitter that the search aircraft, a P-3 Orion, was “unable to locate debris — cloud and rain limited visibility — further aircraft to continue search.” Later, a United States Navy P-8A Poseidon also returned from searching the target area to an air base near Perth, the capital of Western Australia, and “had nothing of significance to report,” according to a message from the United States Seventh Fleet, which is overseeing the American military contribution to the search. Cmdr. William J. Marks, the spokesman for the fleet, said in an email that the Poseidon had found “no indication of debris.”

Climate change "spreads crop pests"

 

Global warming is helping pests and diseases that attack crops to spread around the world, according to a new study published in the journal Nature Climate Change.

Researchers from the universities of Exeter and Oxford have found that crop pests are moving towards the North and South poles as regions warm.

The researchers looked at more than 600 crop pests from around the world. These included fungi, such as wheat rust, which is devastating harvests in Africa and the Middle East; insects like the mountain pine beetle that's destroying trees in the US; as well as bacteria, viruses and microscopic nematode worms.

They found that over the past 50 years, these destructive species have been on the move. On average, they're spreading 3 km every year, shifting north and south towards the poles.

The scientists say this correlates with warming temperatures, allowing the pests to take hold in areas that were once too cold for them to live in.

Currently, between 10 % and 20% of the world's crops are lost to pests and the team warns that rising global temperatures could make the problem worse. The researchers say that improved surveillance of the problem is needed.

Loneliness twice as unhealthy as obesity for older people, study finds

Scientists found that the loneliest were nearly twice as likely to die during their six-year study than the

least lonely

By Ian Sample

 

 

Loneliness can be twice as unhealthy as obesity, according to researchers who found that feelings of isolation can have a devastating impact on older people.

The scientists tracked more than 2,000 people aged 50 and  over and found that the loneliest were nearly twice as likelyto die during the six-year study than the least lonely.

Compared with the average person in the study, those who reported being lonely had a 14% greater risk of dying. The figure means that loneliness has around twice the impact on an early death as obesity. Poverty increased the risk of an early death by 19%.

The findings point to a coming crisis as the population ages and people increasingly live alone or far from their families. A study of loneliness in older Britons in 2012 found that more than a fifth felt lonely all the time, and a quarter became more lonely over five years. Half of those who took part in the survey said their loneliness was worse at weekends, and threequarters suffered more at night.

Previous studies have linked loneliness to a range of health problems, from high blood pressure and a weakened immune system to a greater risk of depression, heart attack and strokes. In his recent book, Loneliness, John Cacioppo, a psychologist at the University of Chicago, says that the pain of loneliness is akin to physical pain.

Elephant Crisis: The Largest Land Mammal Needs our Help

by Dr. Dame Daphne Sheldrick

 

1 Elephants have captured the imagination of

individuals across the world. Majestic beings, they have

fascinated even those who may never have enjoyed close

4 contact with them.

It’s this empathy that has led thousands of people

worldwide today to join the International March for Elephants

7 organized by iworry, a campaign by the David Sheldrick

Wildlife Trust, to publicize the warning that the future survival

of elephants is at serious risk.

10 Some may wonder why elephants matter. I have been

privileged to live amongst them and have nurtured a lifelong

passion to protect them for over 55 years. My team and I have

13 hand-reared more than 160 orphaned elephants to date, some

from the day they were born. It’s a long-term commitment, and

I have known them intimately throughout infancy and

16 childhood into their teenage years and beyond.

Scientific studies of elephants have now led to the

acceptance of abilities that we have observed on a daily basis

19 for many years. Elephants share the same emotions as humans,

with a strong sense of family and the same sense of death. Like

us, they suffer with the loss of loved ones. Each has an

22 individual personality just like us. They can be mischievous,

playful, feel offended or foolish.

In many ways they are better than us, and they have

25 attributes that we humans lack, such as the ability to

communicate over distance using low range sound hidden to

human ears. They have telepathic capabilities, as well as being

28 sensitive to seismic sound through their feet. Yet for all the

worldly reverence for elephants, they are today being hunted

and killed at a catastrophic rate for something as simple as a

31 tooth.

The phenomenon of poaching elephants for their tusks

is not new. It was only through awareness campaigns and

34 international pressure that a ban on the international sale of

ivory was enacted in 1989. This ban provided a brief relief for

elephants by stopping an increasing trade that in some regions

37 caused the loss of up to 80 percent of herds.

However, poaching has escalated in already

devastated populations recently. The interest in ivory

40 stimulated demand, and the result is that elephants are now

being poached at the highest rate since records of their numbers

began. Current estimates put the figure at 36,000 elephants

43 killed annually, which means one elephant dying every 15

minutes.

To date we’ve arrested 1,406 poachers, and our

46 veterinary teams have successfully treated over 500 wounded

elephants.

As long as any trade in ivory remains—legal or illegal,

49 global or domestic—elephants will continue to be cruelly killed

for their tusks.
