Freedom Riders Park has Ala. groundbreaking

A groundbreaking ceremony will be held next week in Alabama to commemorate the location where an iconic Freedom Riders bus was burned more than 50 years ago.

On May 14, 1961, on a trip designed to test a Supreme Court decision banning segregation interstate bus segregation, seven members of the Congress of Racial Equality (CORE) departed from Atlanta on a Greyhound bus. An angry white mob met the bus at a station in Anniston, Ala., where its tires were slashed and windows were shattered. The bus driver later stopped to change a tire and the bus was set on fire as passengers were attacked as they fled. Related attacks in Birmingham drew national and international headlines, leading to a crush of new Freedom Riders, many of whom were jailed.

It was an event that fueled the civil rights movement in a very positive way, said Pete Conroy, co-chair of Freedom Riders Park. It was a bad day that created a more positive future.

The parks design has yet to be finalized, but its four-plus acres on Highway 202 near Anniston between Atlanta and Birmingham, Ala., will contain the exact location where the bus was burned, changing the course of the nations civil rights movement.

This is going to be an outdoor park focusing on this piece of the puzzle, Conroy said. The tone will be entirely positive.

Freedom Rider Bill Harbour, one of the first to exit a bus in Montgomery, where he reportedly encountered a mob of 200 people wielding pipes and baseball bats, survived the riots but saw his life changed forever, beginning with his expulsion from Tennessee State University.

This will be a place for education, contemplation and reflection that shows how a bad event triggered good things, unity and wonderful partnerships, Harbour said in a statement.

The two-part event, which is free and open to the public, will also feature musical and guest presentations. Other Freedom Riders, including Charles Person and Hank Thomas, will also be on hand, as will Janie Forsythe McKinney, who, as a young girl, brought water to Thomas as he fled a burning bus.

The event will continue later that evening at Jacksonville State Universitys McClellan Center, where opera singer K.B. Solomon will present a tribute to singer-civil rights activist Paul Robeson.

Im so pleased to have the opportunity to visit my Anniston home, experience the excitement of a new unity and perform to what is sure to be my favorite audience ever, Solomon said in a statement.

Students see need to protect eco system

137 species were being destroyed every day due to deforestation, and it was estimated that 10 per cent of the existing species would get extinct by 2050 if the ecosystem was not maintained

Students of Rajiv Gandhi University of Knowledge Technologies (RGUKT) have appealed to people to stop destroying forests and natural bodies, and conserve wildlife.

The students, through Power-Point presentations, explained about the threat to mankind and other species owing to indiscriminate exploitation of natural resources, use of pesticides and insecticides, and release of toxic gases into air.

Nuzvid RGUKT Director Ibrahim Khan said following instructions from the Higher Education Department, the institute management organised seminars and debates on Biodiversity and conservation of wildlife on Saturday.

Budding engineers stated that 137 species were being destroyed every day due to deforestation, and it was estimated that 10 per cent of the existing species would get extinct by 2050 if the ecosystem was not maintained.

In a debate, students P. Lavanya and D. John Kiran of PUC detailed how the flora and fauna was being killed in rivers and sea due to release of chemicals and treated water by some industries into canals and rivers. Another student P. Vennela urged people to stop using polythene and plastic material and encourage the use of cotton and jute bags to stop groundwater pollution.

She appealed to the residents to conserve rainwater to increase the groundwater table.

Prof. Khan suggested to the students to work out how ecology was being destroyed in the rural areas during Dasara vacation. He asked the youngsters to explain to the villagers about the consequences of environment pollution.

[Thursday] was the first day of rain in some time in our city, and a visit to our coast, particularly a beach where the sewer meets the surf, would have provided the visitor with a disgusting odor, creating almost a gag reaction. Its clear why our waters are unsafe to be in for days if not weeks after a rain.

This really has to change.

Our city has a long list of needs, far longer then our present political candidates and office holders are willing to address. While our present, mayoral candidates argue over whether to use our growing hotel tax (TOT) for better pensions or a larger convention center, here is hoping that the people of San Diego will demand [the TOT] be used to clean our beaches and bays, making them safe for our families and our tourists.

Jan Goldsmiths commentary (Legalizing medical marijuana properly, Opinion, Oct. 11) is skewered with misleading facts and a looks good on paper federal solution to pot by requiring weed be sold to only people who are dying. Really? What about the 5,000-plus remainder of us who arent seriously ill or hospice bound? Do you think the 5,000-plus are going to stop smoking weed? Or will they revert back to the past of the street distribution network?

How could someone with an education in law enforcement and politics be so obtuse and I mean imperceptive? Really. His is no solution. There will still be have and have-nots with marijuana. Nothing will change, except crime will go up. Kirk Perry, Cardiff

India presents growing opportunity for Canada's aerospace sector: trade advocate

By Ross Marowits, The Canadian Press

MONTREAL - Canada's aerospace sector can create jobs at home by taking advantage of India's modernization and recent moves to liberalize its foreign ownership restrictions, says the head of the Canada-India Business Council.

The world's most populated democracy has been growing in the shadows of fellow Asian giant China and other regional powers. But with India investing billions of dollars a year in infrastructure, the country is expected to jump to become a top five aerospace country by 2020.

"I think there is a real opportunity for us," council president Rana Sarkar said in an interview from Toronto.

"They're not going to go with one supplier, they're going to go with a syndicate of suppliers and it's for us to be in that mix is an important thing."

Canadas aerospace and space sectors generate annual revenues of over $22 billion and employ about 80,000 Canadians in more than 400 firms across the country. Companies such as Bombardier (TSX:BBD-B.TO - News) and CAE Inc. (TSX:CAE.TO - News), along with engineering and construction firms are already pushing to take advantage of the growing demand for new aircraft, pilot training and airport construction.

But more potential remains untapped.

"In virtually every sector in the aviation business, this is sort of like the 1950s in North America. You're starting to see just an arithmetic growth," he said.

The opportunity could total $1 trillion. And even though Canada's share will be small, it's still significant compared to where Canada's sector has been historically, Sarkar said.

Canadian exports to India increased by 29 per cent last year to nearly $2.6 billion, with aircraft and spacecraft being the fourth-largest category accounting for almost nine per cent of total exports. Overall bilateral trade totalled $5.1 billion but is targeted to reach $15 billion by 2015.

A growing cluster of aerospace companies in the Inland Northwest is reaping the rewards of a global surge in aircraftproduction.

Its also setting the table for a main course that could nourish the economy much like health care and education dotoday.

The ultimate prize would be an assembly or manufacturing plant employing a thousand or more workers. Its not a pipe dream when one considers the foundation in place in Spokane County and North Idaho, economic development leaderssay.

I think we are on the precipice of a real advance, said Rich Hadley, president and CEO of Greater SpokaneIncorporated.

In Spokane County alone, more than 80 direct and indirect suppliers for the aerospace industry employ more than 8,000 people, GSI officialsestimate.

North Idaho is building an aerospace cluster of its own, with three dozen companies employing about 650, state officials say. And North Idaho College recently received a $2.97million federal grant to train people for aerospacework.

The region can tout an attractive workforce size, lower labor costs than the Puget Sound area, new investment in education and training, large chunks of land ready for development, airports eager to court new business, and growing collaboration between establishedcompanies.

New DNA hunt for killer of Dutch schoolgirl

The Irish Times - Monday, October 15, 2012

PETER CLUSKEY in The Hague

DUTCH police have carried out the biggest DNA sweep in the history of the Netherlands, taking samples from more than 6,500 men in 12 separate villages, in a renewed attempt to solve the countrys most infamous murder that of 16-year-old schoolgirl Marianne Vaatstra, in 1999.

The DNA sampling was completed on Thursday, and police said at the weekend that they had successfully collected samples from 89 per cent of the 7,300 men still living within a five-mile radius of the meadow where Vaatstras body was dumped 14 years ago.

The schoolgirls age and the particularly gruesome nature of the murder she was raped, strangled and had her throat cut caused revulsion in the Netherlands. As a result there have been repeated attempts over the years to find her killer, most recently in 2007 using 3D technology.

The department of justice has refused on a number of occasions to give permission for such a wide sweep, but in June it relented on the grounds that DNA testing has become much more sophisticated and that police say they may have some of the killers DNA, which was discovered at the scene.

Hopes of a breakthrough now centre on a Playboy cigarette lighter found in the grass near the victims body in the field in Veenklooster, in the northern province of Friesland.

DNA found on the lighter, which was bought in a local shop, matches DNA found on the dead girls body and police hope it may still lead them to someone closely related to the killer.

One of the most controversial aspects of this murder case in 1999 was that, because the body was found near a centre for asylum seekers, the focus of the investigation and of local anger rapidly became the refugees.

An Iraqi who had recently left the camp was detained in the UK, while an Afghan was detained in Turkey. Both voluntarily gave DNA samples and were ruled out.

DNA 'clears magnate of kidnapping'

THE owner of Argentina's powerful Clarin media group wants kidnapping charges dropped after DNA tests failed to link her adopted children to those stolen during the country's 1976-1983 "dirty war," her newspaper has reported.

The request, filed on Friday, comes after DNA samples submitted by the two adult children of Ernestina Herrera de Noble showed no matches with a DNA data bank of relatives of those who disappeared during the dictatorship.

Some 30,000 people vanished during the military's war on leftist activists.

The Grandmothers of the Plaza de Mayo, which represents female relatives of dictatorship-era victims, alleges that some 500 babies were stolen from those who disappeared - and then were adopted by pro-junta families.

Of those, only 107 have been identified.

The kidnapping case against Herrera de Noble was originally filed in 2001, and, after years of legal manoeuvering, a court ordered Marcela and Felipe Noble Herrera to submit to the DNA testing.

"There is no more cross-checking to do," attorney Gabriel Cavallo told the daily Clarin.

The case should be closed because "the experts have already determined that neither Felipe nor Marcela are the children of people who disappeared during the dictatorship," Mr Cavallo said.

But the Grandmothers of the Plaza de Mayo were not ready to admit defeat.

The group has long suspected the Noble Herrera children, both born in 1976, were kidnapped. It says the data bank is being still being updated because many people did not know that their daughters or daughters-in-law were pregnant at the time they vanished.

Biology Systems Engineering nabs grant

WSU researchers will examine food safety following a grant received by the Department of Biology Systems Engineering.

The department was recently awarded the $238,500 grant from the National Needs Fellowship to further research and train doctoral students to promote environmentally friendly means of food production, processing and storing.

The grant will allow three WSU doctoral students to acquire proper training for developing positive food engineering techniques and technologies. They will work with both corporations and U.S. federal agencies to further their studies.

This is a very important grant that both recognizes ground-breaking research in food safety and the need to educate a new generation of leaders in this area, said Howard Grimes, vice president for research and dean of the WSU graduate school.

The new grant will be used to further develop solutions for the constant conflict between providing a large enough food supply for an increasing population as well as meeting the crisis for new energy and environmental requirements, according to a WSU News release.

It is essential that we continue to develop innovative technologies, such as our new microwave that is being introduced globally as a replacement to pasteurization, and research scientists that will continue to discover new ways to keep our food healthy, Grimes said. This grant will do both.

The grant allows WSU researchers to be some of the top in the field and continue to create better technologies for the future of food sciences. It will also allow WSU to maintain its leadership on a global scale in the field of advancing innovative approaches for sustainability, according to the press release.

The three doctoral students participating in this training will be taught through not only classroom techniques, but research environments as well. The overall grant is intended to teach future leaders how to increase and advance food safety, as well as health and wellbeing in an eco-friendly way.

Juming Tang, WSU professor and one of the three researchers participating in the training, stated in the press release that the program supports WSU's vision to become a world leader in developing advanced solutions for safe food production.

The entire grant, titled Educating Food Engineers to Develop High-Performance Integrated Processing and Packaging Technologies that Enhance Food Safety & Quality, is funded by the U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture.

Achieving the 80/20 Point in General Health is Easy, But Anything More is Near Impossible

So the future of medicine is golden, biotechnology is in the throes of a vast expansion of capabilities and free-fall in costs, and we have a good idea as to how to go about reversing aging - if the research community would just stop tinkering with efforts to merely slow down aging and get on with achieving the all-round better goal of rejuvenation. We should all donate money and time to help out, because it's not as though we can take it with us and irreplaceable time is ticking away. A shot at lifespans of centuries and longer is coming, with not so much time left in which to reach for that goal.

Putting all of that to one side for the moment, there is the arguably less important question of how to optimize heath and life span given the present poor tools to hand. Many people spend a great deal of time talking and debating on this topic, immersing themselves in the world of what presently exists, and giving little thought to what might lie ahead. A vast industry caters to people who think they've found the better mousetrap when it comes to personal health and aging. They're all wrong, of course, but that doesn't stop the flow of commerce.

The sad truth of the matter is that it's simple and easy to achieve the 80/20 result in health and longevity within the bounds of the tools we have available to us today, provided you're starting out as a basically ordinary, healthy individual. Exercise regularly, the 30 minutes daily of aerobic exercise that has been recommended by physicians since way back when, and practice calorie restriction with optimal nutrition - i.e. eat a sane diet, not very much of it, and obtain the necessary levels of micronutrients while doing so. There's also the matter of not harming yourself greatly, but just as I shouldn't have to mention avoidance of knives and falling rocks, I shouldn't have to mention things like giving up smoking.

These things are not rocket science. They are widely known and most have been advocated for centuries. The supporting statistical data is far better now than at any point in the past, and so you have no excuses: if you're not adopting these practices then it is because you have decided to accept a shorter life expectancy and greater odds of ill health in exchange for the dissipations that you presently enjoy. No-one's perfect, right?

But here is an interesting thing about trying to reliably forge ahead beyond the 80/20 point in personal health, in search of the optimum level of improvement: it's next to impossible to go further or reliably measure that you have gone further. The research community has expended billions without being able to determine how you can do that - so what makes you think that you can do any better given your far more limited resources? Metabolism and its interactions are so very, very complex. We can list with some confidence what is good for you, but talking about what is optimal is far beyond present capabilities.

For example, to pick one line item, let us consider calorie restriction. It works amazingly well in short-lived animals and improves short-term measures of human health far more than any presently available medical technology can manage. But once we get to an examination of longer lived animals (such as we primates) over the long term, it starts to become much harder to pin down the best, most optimal way to do things - certainly, the present primate studies are beginning to look as though they will generate as much ambiguity as data.

Dietary Restriction: critical cofactors to separate healthspan from lifespan benefits

Dietary restriction (DR), typically a 20-40% reduction in ad libitum or "normal" nutritional energy intake, has been reported to extend lifespan in diverse organisms including yeast, nematodes, spiders, fruit flies, mice, rats and rhesus monkeys. The magnitude of the lifespan enhancement appears to diminish with increasing organismal complexity. However, the extent of lifespan extension has been notoriously inconsistent, especially in mammals.

Recently, Mattison et al. report that DR does not extend lifespan in rhesus monkeys in contrast to earlier work of Colman et al. Examination of these papers identifies multiple potential confounding factors. Among these are the varied genetic backgrounds and composition of the "normal" and DR diets. In the monkeys, the correlation of DR with increased healthspan is stronger than that seen with lifespan, and indeed may be separable. Recent mechanistic studies in Drosophila implicate non-genetic cofactors such as level of physical activity and muscular fatty acid metabolism in the benefits of DR. These results should be followed up in mammals. Perhaps levels of physical activity among the cohorts of rhesus monkeys contributes to inconsistent DR effects.

To understand the maximum potential benefits from DR requires differentiating fundamental effects on aging at the cellular and molecular levels from suppression of age-associated diseases, such as cancer. To that end, it is important that investigators carefully evaluate the effects of DR on biomarkers of molecular aging, such as mutation rate and epigenomic alterations. Several short-term studies show that humans may benefit from DR in as little as 6 months, by achieving lowered fasting insulin levels and improved cardiovascular health.

Optimized healthspan engineering will require a much deeper understanding of DR.

That last sentence is worth considering at length - but remember that the 80/20 win for personal health is still right here, easily achieved. Instead of trying to go further in a presently impossible attempt at optimization, a better use of that time and energy lies in supporting research and development of rejuvenation biotechnology. Even a magically optimized personal health program would not allow most people to live to 100 with today's technology - the only way that the vast majority of us will get to see a three digit birthday cake is through progress in longevity science and its clinical applications.

So if you're going to spend any effort on this whole living longer in good health thing, spend it wisely. Don't chase rainbows.

Comparing Longevity and Damage Resistance in Bivalves

Much like mammals, bivalve molluscs exhibit a very wide range of life spans. At the known outer end stands the arctic quahog at more than four centuries, and much studied in recent years so as to understand the roots of its longevity. That research project is still ongoing, as are similar comparative studies of aging and longevity in a range of other species.

Here, researchers compare resistance to various forms of physical stress and damage in different bivalve species. As you might expect from the view of aging put forward earlier today, longer-lived species are more resistant to most forms of damage:

Bivalve molluscs are newly discovered models of successful aging. Here, we test the hypothesis that extremely long-lived bivalves are not uniquely resistant to oxidative stressors (eg, tert-butyl hydroperoxide, as demonstrated in previous studies) but exhibit a multistress resistance phenotype.

We contrasted resistance (in terms of organismal mortality) to genotoxic stresses (including topoisomerase inhibitors, agents that cross-link DNA or impair genomic integrity through DNA alkylation or methylation) and to mitochondrial oxidative stressors in three bivalve mollusc species with dramatically differing life spans: Arctica islandica (ocean quahog), Mercenaria mercenaria (northern quahog), and the Atlantic bay scallop, Argopecten irradians irradians (maximum species life spans: more than 500, more than 100, and ~2 years, respectively).

With all stressors, the short-lived A i irradians were significantly less resistant than the two longer lived species. Arctica islandica were consistently more resistant than M mercenaria to mortality induced by oxidative stressors as well as DNA methylating agent nitrogen mustard and the DNA alkylating agent methyl methanesulfonate. The same trend was not observed for genotoxic agents that act through cross-linking DNA. In contrast, M mercenaria tended to be more resistant to epirubicin and genotoxic stressors, which cause DNA damage by inhibiting topoisomerases.

To our knowledge, this is the first study comparing resistance to genotoxic stressors in bivalve mollusc species with disparate longevities. In line with previous studies of comparative stress resistance and longevity, our data extends, at least in part, the evidence for the hypothesis that an association exists between longevity and a general resistance to multiplex stressors, not solely oxidative stress.

In mammals, you might look to the naked mole rat as an analogous species: very resistant to all sorts of biological and cellular damage, and extremely long-lived in comparison to similar sized rodent species.

Considering Longevity in Terms of Damage Versus Damage Repair

Here is a framework for thinking about aging and longevity: various forms of low-level biological damage accrue as a result of the operation of metabolism, degrading organs and tissues and ultimately causing death. Where natural selection favors longer-lived individuals, mechanisms will evolve to repair, minimize, or resist the effects of this damage. So aging is driven by damage, but genetic programs interact with that damage, evolved to try to do something about it.

Thus we could expect to be able to manipulate life span either by repairing damage or by altering the programs. The former approach should produce far more effective means of healthy life extension, however, including rejuvenation of the old. In comparison, and from what we've seen so far in longevity science, modestly slowing aging is about the best we can expect from the near future of genetic and metabolic alterations.

In spite of exciting new insights into regulatory mechanisms that modulate the aging process, the proximal cause of aging remains one of the unsolved big problems in biology. An evolutionary analysis of aging provides a helpful theoretical framework by establishing boundary conditions on possible mechanisms of aging. The fundamental insight is that the force of natural selection diminishes with age. This does not preclude senescence (age-related decrease in individual fitness) from occurring in natural populations. Senescence can develop because some genes have non-separable, but typically different or opposite, functions in reproductive-age and in old individuals. Such genes, selected according to their "youthful" function, may thus impose a distinct senescent phenotype in old age.

In general, however, unless a controversial formulation of group selection is invoked, traits that would become manifest only in old age cannot evolve. This precludes the evolutionary emergence of aging programs, which have been sometimes postulated to exist in analogy to developmental and other biological programs. (By the same token, selective pressure that diminishes with age would also prevent extreme longevity from evolving, if "extreme" denotes a potential life span much longer than that imposed by extrinsic mortality in a given environment.) This and other arguments against the existence of an aging program have been discussed previously.

The evolutionary perspective sketched out above does not specify the mechanisms that underlie aging, but it helps to narrow down the possibilities. As already discussed, an evolved deterministic aging program can be ruled out, perhaps with the exception of specific niche situations. In the absence of adaptive life-curtailing processes driven by a putative aging program, we are left with untargeted pro-aging, destabilizing phenomena which, in principle, may range from purely stochastic to side-effects of "legitimate" biochemical pathways. These destabilizing forces are counteracted by evolved, and genetically controlled, longevity assurance (or repair/maintenance) processes. The interplay of these countervailing forces determines the life span.

While I have previously presented my detailed interpretation of this model, its central tenets bear repeating: (a) the destabilizing processes that drive aging are neither evolved nor adaptive; (b) in contrast, longevity assurance mechanisms are under genetic control; (c) together, these two opposing forces determine life span; (d) the average life span of a species is set by evolving longevity assurance mechanisms so as to optimize reproductive success under environmental conditions typical for that species.

Stem Cell Transplants as a Way to Regenerate Myelin

Stem cell therapies offer all sorts of possible ways to intervene in disorders of the brain and nervous system: the evidence suggests that, as for other parts of the body, there is a lot that can be achieved by dropping in a bunch of fully functional cells of the right type and letting them get to work. Or, alternately, by finding ways to stimulate existing cell populations into working harder.

Most of these approaches fall into the category of patches: increasing the pace of repair and recreation of destroyed resources, but doing little to address the underlying reasons for damage and destruction. As a strategy this is second-rate, especially in the brain, but it is how the mainstream of medical research proceeds. In part we can blame regulatory bodies for the focus on patching end results rather than preventing root causes: the way in which requirements and costs are imposed on the development of new therapies leads to a situation in which it the less expensive (and in some cases only) path is to build treatments for late stage disease.

Damage to myelin, the sheathing for axons in nerve cells, is at the root of a number of serious medical conditions. As is the case for most of our biology the integrity of myelin declines with age; some fraction of the age-related decline in cognitive function that occurs for everyone is thought to stem from progressively less effective myelination in the brain. A number of research groups are engaged in ongoing work with stem cells aimed at the repair of myelin, and here is one example:

Stem Cells Myelinate Human Brain

Neural stem cells transplanted into the brains of people with Pelizaeus-Merzbacher disease (PMD) can differentiate and begin producing the myelin sheaths that these patients lack, according to results of a Phase I clinical trial. ... If the stem cell transplants do ultimately demonstrate benefit, they could help more than just PMD patients ... There's a wide range of possible myelin disorders that could be targeted, including demyelinating disorders like multiple sclerosis and preterm babies at risk for cerebral palsy due to white matter injury.

Here, as in many other cases, a therapy is under development for use with specific named diseases - but it might also prove helpful as a treatment for aging, as an attempt to retard loss of cognitive function. Yet there is no path to legally produce therapies for general use in all old people in the US: the FDA doesn't recognize treatment of aging as a legitimate use of medicine, and short a revolution there's little hope of changing that situation through existing paths. Until this changes, a great deal of promising work will be sidetracked into narrow usage for late stage specific diseases, and any real progress towards clinical applications for aging will have to happen outside the US research community.

Treating Neurodegeneration by Increasing Neural Plasticity

One line of research into treatments for neurodegenerative disorders involves spurring the brain to establish new neural connections to replace those that have been damaged or lost. This seems like an inferior strategy in comparison to trying to identify and remove root causes, one that can only delay the inevitable, but it's nonetheless a fairly entrenched field of work.

Here is an example of this sort of research - and note that as for other similar efforts there are hints that an induced increase in neural plasticity would be beneficial for cognitive function in all older individuals:

Researchers have developed a new drug candidate that dramatically improves the cognitive function of rats with Alzheimer's-like mental impairment. Their compound, which is intended to repair brain damage that has already occurred [by] rebuilding connections between nerve cells.

[The scientists] have been working on their compound since 1992, when they started looking at the impact of the peptide angiotensin IV on the hippocampus, a brain region involved in spatial learning and short-term memory. ... angiotensin IV, or early drug candidates based on it, were capable of reversing learning deficits seen in many models of dementia. The practical utility of these early drug candidates, however, was severely limited because they were very quickly broken down by the body and couldn't get across the blood-brain barrier.

Five years ago, [the scientists] designed a smaller version of the molecule [called] Dihexa. Not only is it stable but it can cross the blood-brain barrier. An added bonus is it can move from the gut into the blood, so it can be taken in pill form. The researchers tested the drug on several dozen rats treated with scopolamine, a chemical that interferes with a neurotransmitter critical to learning and memory. Typically, a rat treated with scopolamine will never learn the location of a submerged platform in a water tank, orienting with cues outside the tank. After receiving the [drug], however, all of the rats did, whether they received the drug directly in the brain, orally, or through an injection.

[The researchers] also reported similar but less dramatic results in a smaller group of old rats. In this study the old rats, which often have difficulty with the task, performed like young rats. While the results were statistically valid, additional studies with larger test groups will be necessary to fully confirm the finding.
