Campaigning for Africa’s Research and Development

Commentary/Ghana/Africa

It is encouraging to hear these days the constant talks about research and development (R&D) in Ghana’s/Africa’s progress. Propositions of setting up high-level research and training institutes in crucial fields such as green technology, crop improvement, tropical medicine, deforestation, water supply and desertification are becoming daily issues not only in Ghana but in one part of Africa or another.

At issue aren’t the arguments that part of African states’ Gross Domestic Product (GDP) be given to R&D but also how the mass media should appropriately communicate the R&D results to Ghanaians/Africans. You watch CNN’s Dr. Sanjay Gupta or read Time magazine’s Jeffrey Kluger and you get the message. Eugene H. Amonoo-Neizer, chair of Ghana’s Council for Scientific and Industrial Research (CSIR), says Accra should set aside a percentage of its GDP for R&D. The Ghana mass media is yet to communicate to Ghanaians and Africans how the CSIR’s intercession in the shea butter industry has enhanced the industry so good that it is now growing faster and may beat Ghana’s ancient major cash crop cocoa.

The initial point is how African governments will think indisputably about R&Ds in their development processes, finance them and appropriate the results for development. African governments need not be told about R&D, the elites know the benefits all too well. In 2005, African Ministers of Science and Technology approved the ambitious Consolidated Plan of Action for Africa’s Science and Technology (CPA, 2008-2013) to beef up the wobbly African science and technology capacity.

Amonoo-Neizer is merely reminding African governments that it is an African Union’s protocol they signed which mandated them to set aside one per cent of their GDP to R&D. Rather, most African governments are concerned with excessive spending on defence. As Africa’s democracy deepens, critical questions are being asked openly about development indicators, most of which qualities are better shaped by R&D. Why are Africans’ life expectancies so low and so many people dying in their 50s? Why are infant mortalities so bad? Why do people think death is caused by witchcraft? Despite abundant water, why are Africans thirsty?

Despite these, the small R&D outcomes aren’t communicated to Africans. Though Ghanaians are one of the leading producers of cocoa, it was only recently that they got to know about the health benefits of cocoa. The Western world, where R&D is high and backed by superb health communications networks such as United States’ produced The Doctors and Dr. Oz, had known about cocoa’s health benefits years before Ghanaians, and they consume cocoa (and use it for other products) more than Ghanaians.

Olugbemiro Jegede, secretary general of the Association of African Universities, in Accra, grumble about the dearth of communications between researchers and the mass media to Africans. “Africa can only develop and tell the world about its research capacity if the media put out put relevant information … The gap between the public and research continues to widen because journalists are not bridging that gap. Africa needs to transform to ensure that whatever we are spending on research translates into results.”

In the absence of poor R&D and inadequate communications, certain cultural inhibitions that need scientific interpretations have been entangling Africans’ advancement continue to grow, and entrapping the supposedly highly educated. In the year 2011, backed by solid scientific research, Ghanaians/Africans should have less to do with issues of witchcraft, false prophets, demons and evil spirits. In 2011, it is still the irrational ancient way, and more so.

Olugbemiro Jegede and Eugene Amonoo-Neizer reveal Africans attempt to raise their R&D profiles regardless of challenges such as lack of funding. UNESCO (United Nations Educational, Scientific and Cultural Organization) acknowledges Africans’ new interest in R&D. “A growing number of African countries have realized that, without investment in science and technology, the continent will remain on the sidelines of the global economy and will find it difficult to bring an end to extreme poverty.”

UNESCO sees Africa’s R&D hopeful signs from the fact that recently several African countries such as South Africa, Kenya, Nigeria and Burkina Faso have enacted laws supporting biotechnology and bioscience researches. In 2008, 14 countries (Benin, Botswana, Burundi, Central African Republic, Democratic Republic of Congo, Côte d’Ivoire, Madagascar, Malawi, Morocco, Senegal, Swaziland, Togo, Zimbabwe and Zambia) called on UNESCO to help review their science policy. And, since 2005, six new science academies have been set up in Mozambique, Sudan, Mauritius, Morocco, Tanzania and Zimbabwe, compared to just nine in the entire period from 1902 to 2004,” UNESCO reports.

As Eugene Amonoo-Neizer said, UNESCO has the same opinion that the development of Africa’s science and technology sector faces a number of challenges, starting with budgetary constraints. “Research and development (R&D) attracts considerably less public investment in sub-Saharan Africa than defence, education or health. The proportion of GDP devoted to R&D averages about 0.3% on the continent, seven times less than that spent by industrialized countries on this sector.”

But Eugene Amonoo-Neizer should have used his forum at the Germany-funded Savannah Agricultural Research Institute, in Ghana’s Northern Region, to move beyond African governments’ low funding of R&D. UNESCO will do that for Eugene Amonoo-Neize: “Brain drain, fostered by the absence of measures to promote research and innovation, the gaps in legislation to protect intellectual property and the low wages earned by scientists, constitutes a major concern. In 2009, at least a third of African scientists or those with engineering degrees were living and working in developed countries. The absence of measures to encourage innovation, gaps in the legislation regarding intellectual property rights and low salaries paid to researchers have all contributed to the brain drain.”

In the efforts to resolve these barriers, the battle for the soul of Africa’s research and development will be waged by “rendering science more attractive to pupils in secondary schools and to students.” And yes, a good dose of international scientific cooperation to keep the emerging African scientific soul warm.

Harmonizing the Unrealistic Education System

Commentary/Ghana/Africa Education

The mass failure of Junior High School students at this year’s national examination, a worsening trend over the past couple of years, has sent educationists, parents, the mass media and Accra scrambling for answers. Is it the quality of teachers? Is it lack of educational material? Is it the environment? Is it the nature of the education structure that is frequently ruffled by ruling political parties? Is it the content of the curriculum? Are the education policies realistic? Is it the lack of the broader use of Ghanaian languages? Is it lack of deeper attention to educational issues?

The long-running education crisis reveals that after years of tussles to construct education content that actually reflects its Ghanaian/African appendages in relation to global linkages, there are still worrying schisms within the education system that undermine Ghana’s core progress. The science sector of the education system is still feeble. Research and Development (R&D) is nothing to write home about. Continue reading “Harmonizing the Unrealistic Education System”

Cause of Hypoglycaemia Found, Say Researchers

The cause of a rare and severe form of hypoglycaemia – or very low levels of sugar in the blood – is genetic, say researchers.

The life-threatening condition means the body does not have enough energy to function.

Scientists at the University of Cambridge say mutations in the AKT2 gene are to blame.

Writing in the journal Science, they say there are already cancer drugs which target a similar process.

Hypoglycaemia can be caused by a disruption in the balance between the hormone insulin and sugar. Insulin lowers the level of sugar in the blood.

The condition is commonly associated with Type 1 diabetes, when the patients inject too much insulin, miss a meal or drink alcohol.

‘Bad Romance’ Hurts Online Singles

More than 200,000 people in the UK may have fallen victim to criminals who woo them online to steal their money.

The first formal study of so-called romance scams found that they were far more common than previously thought.

Among those surveyed by researchers at the University of Leicester, one in 50 knew someone who had been a victim.

Perpetrators typically set up a fake profile, pretend to enter into an online relationship then ask for cash to help with financial problems.

Police advice to the public is never to give money to anyone that they have only met over the internet.

The Leicester University team found that more than half (52%) of the 2,000 people surveyed for the study had heard of the scam with 2% personally knowing someone who had been targeted.

Double hit

Action Fraud, the national fraud reporting and advice centre run by the National Fraud Authority, identified 592 victims between 2010 and 2011.

However, the researchers believe that many more probably go unreported.

“It may well be that the shame and upset experienced by the victims deters them,” said Prof Monica Whitty.

She explained that the psychological impact could be huge and suggested that new methods of reporting the crime were needed.

“It is our view that the trauma caused by this scam is worse than any other, because of the ‘double hit’ experienced by the victims – loss of monies and a ‘romantic relationship’,” said Prof Whitty.

Grooming

The criminals who carry out romance scams typically use online dating sites or social networks to identify targets and devote time and effort to “grooming” them, according to the Serious Organised Crime Agency (Soca).

It said that most will attempt to move the relationship away from monitored online places before defrauding people.

Soca view romance fraud as organised crime, usually operated from outside the UK.

“The perpetrators spend long periods of time grooming their victims, working out their vulnerabilities, and when the time is right… ask for money,” said Soca’s senior manager for fraud Colin Woodcock.

Investigations by Soca have found that people can give the criminals anything between £50 to £240,000.

In some cases, when they fail to get money out of victims, the criminals ask them to accept money into their account as part of a wider money laundering operation, said Mr Woodcock.

“It is crucial that nobody sends money to someone they meet online, and haven’t got to know well and in person,” he added.

NASA Satellite/Space Junk Hits Earth, Space Agency Confirms

NASA’s dead six-ton satellite fell to Earth early Saturday morning, starting its fiery death plunge somewhere over the vast Pacific Ocean.

Details were still sketchy, but the U.S. Air Force’s Joint Space Operations Center and NASA say that the bus-sized satellite first penetrated Earth’s atmosphere somewhere over the Pacific Ocean. That doesn’t necessarily mean it all fell into the sea. NASA’s calculations had predicted that the former climate research satellite would fall over a 500-mile swath.

The two government agencies say the 35-foot satellite fell sometime between 11:23 p.m. EDT and 1:09 a.m. EDT. NASA said it didn’t know the precise time or location yet.

Some 26 pieces of the satellite – representing 1,200 pounds of heavy metal – were expected to rain down somewhere. The biggest surviving chunk should be no more than 300 pounds.

The Upper Atmosphere Research Satellite is the biggest NASA spacecraft to crash back to Earth, uncontrolled, since the post-Apollo 75-ton Skylab space station and the more than 10-ton Pegasus 2 satellite, both in 1979.

Russia’s 135-ton Mir space station slammed through the atmosphere in 2001, but it was a controlled dive into the Pacific.

Before UARS fell, no one had ever been hit by falling space junk and NASA expected that not to change. NASA put the chances that somebody somewhere on Earth would get hurt at 1-in-3,200. But any one person’s odds of being struck were estimated at 1-in-22 trillion, given there are 7 billion people on the planet.

Malaria Vaccine Trial Raises Hope

By Matt McGrat,  Science reporter

Researchers are to expand a clinical trial of a new malaria vaccine after promising results in a preliminary study in Burkina Faso.

The trial was designed to test safety, but researchers found that vaccinated children had high levels of protection.

Described as a “most encouraging” result, a larger study involving 800 children is now to take place in Mali.

The scientists involved say they are hopeful that the vaccine will ultimately be very cheap to produce.

Around a hundred different malaria vaccine candidates have been developed to date but the MSP3 vaccine tested in Burkina Faso is only the second one to show a substantial level of protection against the illness.

The randomised, double blind study involved 45 children. It set out to test the safety of the vaccine but this follow up study found that children who received it had an incidence of the disease three to four times lower than children who did not.

Initially the children were split into three groups, with two of them receiving the experimental malaria vaccine developed by Dr Pierre Druilhe at the Pasteur Institute in Paris.

“Those two groups had very similar types of immune response, elicited by the vaccine, and the protection is almost identical, so it reinforces the confidence despite the fact that we are still dealing with a small group,” he said.

The vaccine is based on the fact that some adults in Africa acquire immunity because they are constantly exposed to the disease.

Early days

Dr Druilhe and his team discovered a key protein, MSP3, which provokes the body into producing antibodies that kill the parasite.

He said the protein is unique as it does not change much between different strains of the plasmodium parasite that causes malaria. This is believed to be a critical factor in developing an efficient vaccine.

He added: “We performed a large number of epidemiological studies that confirm that there was an association between that vaccine candidate and acquired protection, so when you immunise with this molecule you indeed induce protection.”

Another scientist involved with the Burkina Faso study was Dr Louis Miller, the former head of the Malaria Vaccine Branch of the US National Institutes of Health.

He said: “I was always in favour of this approach as it offered a chance in a field with few successes. I found the results of this preliminary study in Burkina Faso to be most encouraging.”

High transmission

Encouraged by the early results, Dr Druilhe said the trial has now been expanded to 800 children in Mali. But he remains cautious.

“There have been too many claims of effective vaccines so we have to remain very cautious. It has to be confirmed and we have started on work to do that confirmation. Essentially the trial in Mali is about 20 times larger, in extremely high transmission conditions, so it should yield very clear cut results – this will be black and white.”

The other vaccine candidate that has shown success against malaria is called RTS, S. It has been funded by the Bill and Melinda Gates Foundation and is set to go into production with pharmaceutical giant, GlaxoSmithKline.

But there are concerns that it could be expensive, especially for people in Africa and other regions affected by the disease.

Dr Druilhe says his vaccine could be a lot cheaper – perhaps half a dollar or less a bottle.

Remains of Earliest Human Ancestor Found in South Africa

Remains of human ancestor in South Africa dated at almost two million years

THE remains of what may be our earliest human ancestor have been dated at almost two million years old and may unlock some of the mysteries of human evolution.

The skull of Australopithecus sediba may unlock secrets to human evolution

Expert analysis of the hands, feet, skull and pelvis, published today in the journal Science, offers “unprecedented” access to our family history, and the remains bear striking similarities to both ancient apes and members of our own species, homo sapiens.

The remains of two individuals, a child and a young woman, come from a cave in South Africa.

Human evolution professor Lee Berger, from the University of the Witwatersrand in Johannesburg, made the original discovery in August 2008.

Last year he introduced the world to a new species, Australopithecus sediba or “southern ape, wellspring”.

The “really extraordinary material” has now been dated at 1.977 million years old, and the results can be shared with the rest of world.

“We have the most complete hand from one individual, from any species of early human ancestor ever discovered and it’s a lot like ours, with its shortened fingers and its long thumb,” Professor Berger said.

“We’re getting a vision into the moment where our grip, the thing that makes us so unique, that allows us to play piano, to paint a picture, type on a computer, make a stone tool or shake hands, evolved.

“It’s amazing to see that, particularly on the end of an arm that’s like an ape.”

He said the species also had a “surprisingly advanced but small brain” (420 cubic centimetres) and a very modern pelvis, but the foot and ankle shape combined features of both apes and humans in the one anatomical package.

The many advanced features, and its age make it “possibly the best candidate ancestor for our genus, the genus homo, more so than previous discoveries such as Homo habilis”.

At the University of Melbourne, Dr Robyn Pickering performed uranium lead dating of the flowstone above and below the bones, while colleagues at La Trobe University conducted a palaeomagnetic analysis of sediments surrounding the fossils.

“Knowing the age of the fossils is critical to placing them in our family tree,” Dr Pickering said.

Text Messages Advance Malaria Care

Text messages could be a cost effective way of improving care for African children with malaria, according to researchers.

A six month study involving 119 health workers in Kenya, published by The Lancet, showed texts increased the number following government guidelines.

Half of children received the correct treatment at the end of the study, more than double the starting figure.

Researchers said there was “huge potential” to improve care.

There has been concern that government guidelines on malaria treatments are not always followed in the field.

Guidelines include the correct prescription of anti-malaria drugs – artemether-lumefantrine (AL) – and advice to parents.

Health workers in the study were sent text messages twice a day, five days a week, for six months.

An example of the sort of sent was: “advise mother to finish all AL doses over three days even if the child feels better after two doses”.

Improvement

At the beginning of the study, 20.5% of children were correctly managed, this increased to 49.6% after the six month study.

We need to explore ways of scaling up such intervention to all health workers in the country”

End Quote Dr Willis Akhwale Ministry of Public Health and Sanitation

The effect appeared to persist after the texts stopped. Six months after the trial ended, 51.4% of children were receiving the correct treatment.

Professor Bob Snow, who headed the research group, said: “The role of the mobile phone in improving health providers’ performance, health service management and patient adherence to new medicines across much of Africa has a huge potential.”

The cost of the texts was estimated at £1.59 for the whole six months for each worker.

However, the authors acknowledge that “we do not fully understand why the intervention was successful”.

They suspect it may act as a reminder or reinforce the importance of the messages in the texts.

Dr Willis Akhwale, from the Kenyan Ministry of Public Health and Sanitation, said: “We need to explore ways of scaling up such intervention to all health workers in the country.”

Bruno Moonen and Justin Cohen, from the Clinton Health Access Initiative in Nairobi, said: “A combination of interventions will most likely be needed to improve adherence to national guidelines.”

The study provides “strong evidence that text message reminders can be an effective, low-cost component of such a package”.
