Stay sharper for longer

With the advent of old age, incidences of misplaced keys and embarrassing moments of forgotten names occur more often. As you inch closer to becoming a senior citizen, certain cognitive skills start to decline and others improve. But you can still find some 70-year-olds who can beat those at 50 on a memory test. How do they retain such abilities and how can that knowledge be used to our advantage? Results emerging from unique studies show that there might indeed be ways to slow down the inevitable slide.

Crowdfunding science: Many a mickle makes a muckle

Necessity, so the proverb has it, is the mother of invention. And science is nothing if not inventive. So, as conventional sources of money get harder to tap (the success rate enjoyed by those applying for research grants from the National Institutes of Health, America’s biggest science-funding agency, has fallen from 30% in 2003 to 18% in 2011), some of science’s more creative minds are turning elsewhere.

Philanthropic sponsorship of science, particularly in the form of expensive pieces of kit such as large telescopes, or sponsorship for expeditions to far-off places, has been around for centuries. But the internet now permits what might be thought of as microphilanthropy. Through a technique called crowdfunding, in which members of the public donate small sums to projects they like the look of (sometimes in the knowledge that the donation will be taken up only if sufficient other pledges are made to surpass a stated target), the possibility of scientific philanthropy has been extended to those of more slender means.

On October 4th, for example, Ethan Perlstein, a pharmacologist at Princeton University, launched a bid on a site called RocketHub to collect $25,000 to study the effect of drugs such as methamphetamine on the brain. He has until November 18th to raise the money.

Kristina Killgrove, an anthropologist at the University of West Florida, has already raised over $12,000 on RocketHub to examine the DNA of Roman skeletons. And on another crowdfunding site, Petridish, the California Academy of Sciences (CAS) offered to name any new species of ant discovered during a conservation project in Madagascar after those who donate more than $5,000 to the enterprise.

Although the crowdfunding of science is not raising the sorts of sums sometimes attracted by those with ideas for things like video games, it has already spawned a couple of specialised platforms of its own. Petridish is one. Another is called Microryza. And academic institutions are starting to follow the lead taken by the CAS. The University of California, San Francisco, has made a deal with a site called Indiegogo that will allow the university’s charitable status to make money donated via Indiegogo tax deductible. It will launch the first such project later this month.

Donors can expect no revenue if a crowdfunded science project is successful, of course. But they can expect to be kept up to date with progress. Dr Perlstein has promised to upload all data from his experiments onto a website, for his sponsors to look at. And even those who are not immortalised in the myrmicine literature, as the CAS proposed, may still get a warm glow from the feeling that they are making a contribution to the advancement of knowledge in a way which was previously open only to philanthropists with rather fatter wallets.

Geek philanthropy

An innovative charity rallies geeks for a good cause

Businesses avidly mine data to improve their efficiency. Non-profit groups have plenty of information, too. But they can rarely afford to hire number-crunchers. Now a bunch of philanthropic geeks at DataKind, a New York-based charity, are helping other do-gooders work more productively and quantify their achievements for donors, who like to see that their money is well spent.

A typical DataKind two-day “hackathon” last month in London attracted 50 people who worked in three teams. One pored over the records of Place2Be, which offers counselling to troubled schoolchildren. Crunching the data showed that boys tend to respond better than girls, though girls who lived with only their fathers showed the biggest improvements of all. The charity did not know that.

The expertise is far beyond what is available to a typical charity. The small-talk among the volunteers was of dizzyingly complex statistical and artificial-intelligence techniques. Volunteers included an analyst at Teradata, a data-analytics firm. Around 20 employees attended from Aimia, a firm that mines data from consumer-loyalty programs.

In a previous hackathon in San Francisco, DataKind volunteers analysed the data from Mobilising Health, a non-profit group that connects rural patients in India with doctors in cities that are usually many hours away. Volunteers record symptoms and relay them by cellphones. The doctors then may prescribe drugs or recommend a hospital visit. The charity wanted to use the many months’ worth of accumulated text messages to evaluate the medics’ performance. Thanks to DataKind the charity was able to rejig the system to take more account of urgency and to direct requests to the most responsive doctors.

Thomas Levine, a data scientist at ScraperWiki, a provider of data-processing services, says he has attended DataKind events out of altruism but also for education. Would anyone care to measure that benefit?
