Retired Justice Sandra Day O’Connor knows the daily balancing act that Alzheimer’s caregivers face: When her husband could no longer stay home alone, she had to take him to work with her at the Supreme Court.

Now O’Connor is taking her family’s struggle with Alzheimer’s public as she calls on Congress on Wednesday to spur efforts to fight the nation’s coming dementia epidemic.

“I cannot overemphasize the need for urgency,” O’Connor said in testimony prepared for the Senate Special Committee on Aging. “We must resolve, by our swift action, that the current generation of people with Alzheimer’s will be the last generation that we lose to this miserable disease.”

More than 5 million Americans are living with Alzheimer’s disease, O’Connor’s husband, John, among them. O’Connor stepped down as the first female Supreme Court justice in 2005 to move her husband to an assisted care center in Phoenix, near two of their children. Intensely private, she has said little until now of the family’s experience except that she regretted having to leave the high court so soon.

Alzheimer’s is poised to skyrocket, with 16 million people forecast to have the mind-destroying illness by 2050. Today’s treatments only temporarily alleviate symptoms. Already, the Alzheimer’s Association estimates that 10 million people share the overwhelming task of caring for a relative or friend with it.

“I suspect that you will not hear from many of my fellow caregivers directly … simply because they do not have the resources to take time away from their loved ones in order to come before you,” O’Connor said.

Against that somber backdrop, a group of scientists, former politicians and well-known names like O’Connor have teamed up to create what they call a “national strategy” to jumpstart efforts to speed research into new Alzheimer’s treatments and improve help for caregivers.

The so-called Alzheimer’s Study Group won’t have its report ready until next year, but began pushing lawmakers Wednesday to start thinking about the needed investment despite tight economic times. Public funding for Alzheimer’s has been stagnant for five years, O’Connor noted.

“You will never meet an Alzheimer’s survivor — there are none,” former House Speaker Newt Gingrich, who co-founded the group, said in his testimony.

A Swiss pilot strapped on a jet-powered wing and leaped from a plane Wednesday for the first public demonstration of the homemade device, turning figure eights and soaring high above the Alps.

Yves Rossy’s performance in front of the world press capped five years of training and many more years of dreaming.

“This flight was absolutely excellent,” the former fighter pilot and extreme sports enthusiast said after touching down on an airfield near the eastern shore of Lake Geneva.

Rossy, 48, had stepped out of the Swiss-built Pilatus Porter aircraft at 7,500 feet and unfolded the rigid eight-foot wings strapped to his back before jumping.

Passing from free fall to a gentle glide, Rossy then triggered four jet turbines and accelerated to 186 miles per hour, about 65 miles per hour faster than the typical falling skydiver. A plane that flew at some distance beside him measured his speed.

Global warming is set to stall over the next 10 years as natural variations in ocean currents counteract manmade climate change.

Researchers modelling the climate of Europe and North America found that a major ocean current that brings warm water northwards is set to weaken, potentially offsetting temperature rises caused by human activity.

A team led by Noel Keenlyside at the Leibniz Institute for Marine Science in Germany focused on an ocean current known as the meridional overturning current or MOC. The current acts as a huge conveyor belt, bringing warm water into the North Atlantic and returning cold water to the south.

Scientists believe the ocean current strengthens and weakens on a natural cycle with a 70 to 80-year period. When the current is strong, it brings warmer water and a milder climate to northern regions.

The team’s models, which were checked against historical temperature changes, suggest the current will weaken enough to cool the North Atlantic, while temperatures in the tropical Pacific are unlikely to change.

The study appears in the journal Nature today.

“Our results show that global mean temperatures may plateau or cool weakly over the next 10 years because of natural fluctuations, but in the long term temperatures will continue to rise,” said Dr Keenlyside. “This doesn’t change the bottom line on global warming.”

Reports from the UN Intergovernmental Panel on Climate Change suggest carbon emissions could drive global temperatures up by as much as 0.2C each decade.
