Addis Ababa, Ethiopia — One of the hurdles to improving health care systems for African countries is the shortage of scientists and lack of meaningful medical research on the continent, experts say.
An organization hopes to change that by enabling researchers and policymakers in three large African countries to develop more extensive and relevant research.
According to a 2017 report by the World Economic Forum, Africa is home to 15% of the world’s population and 25% of the world’s disease burden — but produces just 2% of the world’s medical research.
The report said of the medical research that does occur, much of it fails to prioritize diseases or health problems most pressing for Africans.
A group of African health researchers and institutions are now pushing for the continent’s medical research to be more focused on the continent’s own medical problems.
The African Population and Health Research Center is bringing together scientists, academics, policymakers and government officials from Ethiopia, Kenya and Nigeria.
Their goal is to strengthen African leadership in research and development, ensuring that the findings from these researchers are relevant and accessible to decision-makers, leading to better health care systems across the continent.
Catherine Kyobutungi, head of the organization, said African-led research can help solve health problems on the continent much more easily and quickly.
“If we want the research to be done by Africans in Africa on African issues, that is [how] the priorities for what research should be done are defined, not just by academics, but by the people who are going to use that research for decision-making,” she said.
“What we are trying to achieve is to shift what research is and what it is for and to create an army of African scientists that do research to solve African problems in real time, not after 50 years,” Kyobutungi said.
Dr. Hadiza Galadanci, a professor of obstetrics and gynecology at Bayero University in Nigeria, said her country accounts for about 28% of maternal deaths worldwide each year.
She and researchers from four African countries, Birmingham University in the United Kingdom and the World Health Organization published research on the best way to save women who were dying from postpartum hemorrhage, or excessive bleeding after childbirth. Their innovation — a calibrated obstetric drape, which is placed beneath a birthing mother — allows physicians to collect and precisely measure blood and fluid loss.
“The drape is just put under … the woman when she’s going to deliver. And then, as soon as she delivers, any blood that comes out goes to the drape. So, we have an objective assessment,” Galadanci explained, saying that the process allows for more specific treatment.
“When we did this, we found out that we could reduce the rate of severe [postpartum hemorrhage] leading to maternal death by 60%.”
African researchers face challenges ranging from a lack of reliable data and funding to poor infrastructure to cultural and religious issues.
With the support of the Bill and Melinda Gates Foundation, Africa Research Connect was developed to connect and enhance the visibility of scientists, institutions, policymakers and donors.
Jude Igumbor, an associate professor at Wits School of Public Health in South Africa, wants to improve the visibility of African scientists and their work.
“What we give African scientists is they are able to find each other for collaboration,” he said.
The African Population and Health Research Center is calling on donors to fund African institutions and researchers directly instead of going through other organizations, saying that doing so helps the money create opportunities and hone the skills of researchers on the continent.

Washington — When activists, policymakers and representatives from across the globe gather next week in New York to participate in climate week, one pressing issue on the agenda that is less frequently discussed and known will be the environmental impact of seabed mining.
As countries look for ways to lower emissions, critical minerals are playing a key role in that transition. Critical minerals are used in all kinds of green technologies, from solar panels and wind turbines to batteries in electric vehicles. And one place where those mineral resources are abundant is deep under the sea.
The debate over accessing seabed resources is heated. Supporters say the technology exists to safely access these critical minerals undersea, but environmentalists and activists say the potential of undiscovered biodiversity on the seafloor is too important to endanger.
During climate week, which will take place on the sidelines of U.N. General Assembly meetings, organizers are expected to host a roundtable on the environmental impact of seabed mining and other discussions about critical minerals.
The World Economic Forum says that if the globe wants to reach net-zero emissions by 2050, two-thirds of vehicles must be powered by electric batteries. And the International Energy Agency says that to reach that goal, the world needs six times more mineral resources by 2040 than it has today.
Some of the largest mineral deposits are found on the ocean floor in the form of polymetallic nodules, or rocks.
Ocean of resources
According to the International Seabed Authority, or ISA, there are 21 billion tons of polymetallic nodules strewn across the seabed of the Clarion-Clipperton Zone, or CCZ. Each nodule contains a combination of electric vehicle battery components such as nickel, manganese, copper and cobalt. The ISA plans to release regulations for mining in the international waters of the CCZ by 2025.
The ISA has already awarded 17 exploration contracts for polymetallic nodules in the Clarion-Clipperton Zone – a large swath of the Pacific Ocean the size of the continental United States which sits between Hawaii and Mexico. Three of those exploration contracts went to The Metals Company, a Canadian deep-sea mining company.
The Pacific Island Nations of Nauru, Kiribati and Tonga have sponsored The Metals Company’s efforts to develop a portion of the seabed. In an interview with VOA, CEO Gerard Barron said the company is ready to begin as soon as the ISA allows mining.
“Our collector methodology is to put a robot on the seafloor which crawls around the ocean floor and fires a jet of water at the nodule and it creates an inverse pressure and lifts the nodule up, and so we don’t go down and scour the seafloor,” said Barron via Zoom, adding that TMC has spent the past decade focused on testing this equipment and collecting data on its environmental impact as part of its permit application to the ISA.
Moratorium needed
Critics worry scooping up these mineral-rich rocks will disrupt important biodiversity – much of it still unnamed and some of it undiscovered. Researchers have found that 90% of the more than 5,000 species in the zone are new to science. Eddie Palu, president of the Tonga Fishery Association, wants a pause for more research.
“We demand a moratorium on the seabed mining until the environmental, economic and social risk are comprehensively understood,” he said during a panel discussion at the recent Pacific Islands Forum in Tonga.
Shiva Gounden from Greenpeace Australia Pacific, who also sat on the panel, agreed.
“We know only very little of the deep sea, and the race for the final frontier could cause irreversible damages to the people and to the communities of our Pacific,” Gounden said.
But scientists say no light and very little oxygen reaches the deep sea – limiting the life there to mostly bacteria and small invertebrates.
The Metals Company’s Barron said combating climate change is a bigger threat to the planet than undersea mining, adding that the company’s environmental impact studies show that “we can safely collect these nodules” and turn them into battery metals without having “a negative impact on the ocean.”
“The notion that we can do any extraction with zero impact is a dream,” added Barron. “The oceans are impacted by every single thing we do today, especially global warming. So, we need to address the main driver for climate change and reduce emissions.”
Fueling innovation
Still, the quest to do just that – access minerals on the seabed with minimal impact to the environment – has created competition between technology companies.
U.S. tech startup Impossible Metals is testing a robot which can avoid nodules where it detects life and harvests those where it does not.
“The vehicle hovers above the seabed, uses the camera and it actually picks up the nodules one by one. So this really minimizes all of the negative concerns around big sediment plumes,” CEO Oliver Gunasekra told VOA in an interview.
Gunaskera’s company spun off Viridian Biometals. Its technology bypasses energy-intensive processes such as smelting with bacteria which can separate metal ore from the rock around it. The process creates no emissions or waste.
“The bacteria need oxygen just like we do to breathe. And when there’s not enough oxygen in the water around them, the bacteria have learned that there’s oxygen in the rocks, and they have adapted to breathe that oxygen,” said Viridian CEO Eric Macris.
Impossible Metals and Viridian Biometals say they are two to three years out from commercializing their technology, depending on funding. TMC says it could be ready to begin its collection operations as soon as international regulations are released next year.

washington — Two mighty beams of energy have been detected shooting in opposite directions from a supermassive black hole inside a distant galaxy — the largest such jets ever spotted, extending about 140 times the diameter of our vast Milky Way galaxy.
The black hole resides at the heart of a galaxy about 7.5 billion light-years from Earth. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion kilometers). Because of the time it takes for light to travel, looking across great distances is peering back in time, with these observations dating to when the universe was less than half its current age.
Black holes are extraordinarily dense objects with gravity so strong that not even light can escape. Most galaxies, including the Milky Way, have a large black hole at their core. Some of these shoot jets of high-energy particles and magnetic fields into space from their two poles as they devour material such as gas, dust and stars falling into them due to their immense gravitational strength.
The two jet structures documented in the new study — using the LOFAR (Low-Frequency Array) radio telescope, a network of antennas centered in the Netherlands — extend 23 million light-years from end to end.
These super-heated jets, caused by the violent events around the black hole, are composed of subatomic particles called electrons and positrons, and magnetic fields, moving at nearly the speed of light.
The researchers have nicknamed these two jets Porphyrion (pronounced poor-FEER-ee-ahn), named after a giant from ancient Greek mythology. Porphyrion is about 30% longer than the previous record-holder for such jets.
“Jet systems like Porphyrion appear to be among the most energetic spectacles that have occurred in the universe since the Big Bang,” said Caltech astrophysicist Martijn Oei, lead author of the study published in the journal Nature, referring to the event that initiated the universe about 13.8 billion years ago.
“The general understanding is that jets are formed when magnetized material falls onto a rotating black hole,” added astrophysicist and study co-author Martin Hardcastle of the University of Hertfordshire in England. “They need to be sustained by a continued infall of matter into the black hole, something of the order of one solar mass [the mass of the sun] a year of material.”
Such jets, not visible to the naked eye, start out small and grow over time.
“We’ve known for a while that black holes can generate these jets. But what is interesting is that to generate a large structure like this, the jets must stay on for a long time — about a billion years,” Hardcastle said.
The Porphyrion jets reach far beyond their home galaxy, with an energetic output equivalent to trillions of stars like the sun.
“That is equivalent to the energy released during the most cataclysmic cosmic collisions: for example, those that occur when two galaxy clusters, each sometimes containing thousands of galaxies, merge together,” Oei said.
“The fact that it extends so far from its parent black hole means that it may be carrying energy, particles and magnetic fields into the voids in the cosmic web, the gaps between groups and filaments of galaxies which we know make up the large-scale structure of the universe. This may help us to understand the ubiquitous magnetic fields in the present-day universe,” Hardcastle said.
Such jets could heat up gas in interstellar space, shutting down the formation of new stars that require cold clouds of gas, and could damage habitable planets, the researchers said.
The Milky Way’s supermassive black hole, in its current quiescent state, does not have such jets.
“The key finding is that jets from black holes can, if circumstances are right, become as large as the universe’s major cosmic structures — galaxy clusters, cosmic filaments, cosmic voids,” Oei said. “This means that individual black holes can have a sphere of influence that extends way beyond the galaxy in which they reside.”

Washington — The United States has identified and taken down a botnet campaign by China-directed hackers to further infiltrate American infrastructure as well as a variety of internet-connected devices.
FBI Director Christopher Wray announced the disruption of what he called Flax Typhoon during a cyber summit Wednesday in Washington, describing it as part of a much larger campaign by Beijing.
“Flax Typhoon hijacked Internet-of-Things devices like cameras, video recorders and storage devices — things typically found across both big and small organizations,” Wray said. “And about half of those hijacked devices were located here in the U.S.”
Wray said the hackers, working under the guise of an information security company called the Integrity Technology Group, collected information from corporations, media organizations, universities and government agencies.
“They used internet-connected devices — this time, hundreds of thousands of them — to create a botnet that helped them compromise systems and exfiltrate confidential data,” he said.
But Flax Typhoon’s operations were disrupted last week when the FBI, working with allies and under court orders, took control of the botnet and pursued the hackers when they tried to switch to a backup system.
“We think the bad guys finally realized that it was the FBI and our partners that they were up against,” Wray said. “And with that realization, they essentially burned down their new infrastructure and abandoned their botnet.”
Wray said Flax Typhoon appeared to build on the exploits and tactics of another China-linked hacking group, known as Volt Typhoon, which was identified by Microsoft in May of last year.
Volt Typhoon used office network equipment, including routers, firewalls and VPN hardware, to infiltrate and disrupt communications infrastructure in Guam, home to key U.S. military facilities.
The Chinese Embassy in Washington Wednesday rejected the U.S accusations.
“Without valid evidence, the U.S. jumped to an unwarranted conclusion and made groundless accusations” Chinese Embassy spokesperson Liu Pengyu told VOA in an email, responding to the allegations about Flax Typhoon.
“The U.S. itself is the origin and the biggest perpetrator of cyberattacks,” Liu added. “We urge the U.S. to stop its worldwide cyber espionage and cyberattacks, and stop smearing other countries under the excuse of cyber security.”
The FBI and the U.S. Cybersecurity and Infrastructure Security Agency have previously warned that Chinese-government directed hackers, like Volt Typhoon, have been positioning themselves to launch destructive cyberattacks that could jeopardize the physical safety of Americans.
Following Wednesday’s announcement by the FBI, the U.S. National Security Agency (NSA) issued an advisory encouraging anyone with a device that was compromised by Flax Typhoon to apply needed patches.
It said that as of this past June, the Flax Typhoon botnet was making use of more than 260,000 devices in North America, Europe, Africa and Southeast East.
The NSA said almost half of the compromised devices were in the U.S. Another 18 countries, including Vietnam, Bangladesh, Albania, China, South Africa and India, were also impacted.
Tuberculosis remains a critical public health issue in many countries and is a leading cause of death in South Africa. Over the past six years, the BEAT Tuberculosis study, conducted in South Africa and focused on children and pregnant women, has revealed a promising new oral treatment that could mark a significant breakthrough in the fight against drug-resistant TB.

Ratcliffe on Soar, United Kingdom — Ratcliffe-on-Soar Power Station has dominated the landscape of the English East Midlands for nearly 60 years, looming over the small town of the same name and a landmark on the M1 motorway bisecting Derby and Nottingham.
At the mainline railway station serving the nearby East Midlands Airport, its giant cooling towers rise up seemingly within touching distance of the track and platform.
But at the end of this month, the site in central England will close its doors, signaling the end to polluting coal-powered electricity in the UK, in a landmark first for any G7 nation.
“It’ll seem very strange because it has always been there,” said David Reynolds, a 74-year-old retiree who saw the site being built as a child before it began operations in 1967.
“When I was younger you could go down certain parts and you saw nothing but coal pits,” he told AFP.
Energy transition
Coal has played a vital part in British economic history, powering the Industrial Revolution of the 18th and 19th centuries that made the country a global superpower, and creating London’s infamous choking smog.
Even into the 1980s, it still represented 70% of the country’s electricity mix before its share declined in the 1990s.
In the last decade the fall has been even sharper, slumping to 38% in 2013, 5.0% in 2018 then just 1.0% last year.
In 2015, the then Conservative government said that it intended to shut all coal-fired power stations by 2025 to reduce carbon emissions.
Jess Ralston, head of energy at the Energy and Climate Intelligence Unit think-tank, said the UK’s 2030 clean-energy target was “very ambitious.”
But she added: “It sends a very strong message that the UK is taking climate change as a matter of great importance and also that this is only the first step.”
By last year, natural gas represented a third of the UK’s electricity production, while a quarter came from wind power and 13 percent from nuclear power, according to electricity operator National Grid ESO.
“The UK managed to phase coal out so quickly largely through a combination of economics and then regulations,” Ralston said.
“So larger power plants like coal plants had regulations put on them because of all the sulphur dioxide, nitrous oxides, all the emissions coming from the plant and that meant that it was no longer economically attractive to invest in those sorts of plants.”
The new Labour government launched its flagship green energy plan after its election win in July, with the creation of a publicly owned body to invest in offshore wind, tidal power and nuclear power.
The aim is to make Britain a superpower once more, this time in “clean energy.”
As such, Ratcliffe-on-Soar’s closure on September 30 is a symbolic step in the UK’s ambition to decarbonize electricity by 2030, and become carbon neutral by 2050.
It will make the country the first in the G7 of rich nations to do away entirely with coal power electricity.
Italy plans to do so by next year, France in 2027, Canada in 2030 and Germany in 2038. Japan and the United States have no set dates.
- ‘End of an era’ –
In recent years, Ratcliffe-on-Soar Power Station, which had the potential to power two million homes, has been used only when big spikes in electricity use were expected, such as during a cold snap in 2022 or the 2023 heatwave.
Its last delivery of 1,650 tons of coal at the start of this summer barely supplied 500,000 homes for eight hours.
“It’s like the end of a era,” said Becky, 25, serving £4 pints behind the bar of the Red Lion pub in nearby Kegworth.
Her father works at the power station and will be out of a job. September 30 is likely to stir up strong emotions for him and the other 350 remaining employees.
“It’s their life,” she said.
Nothing remains of the world’s first coal-fired power station, which was built by Thomas Edison in central London in 1882, three years after his invention of the electric light bulb.
The same fate is slated for Ratcliffe-on-Soar: the site’s German owner, Uniper, said it will be completely dismantled “by the end of the decade.”
In its place will be a new development — a “carbon-free technology and energy hub”, the company said.

brussels — Europe’s second-top court largely confirmed on Wednesday an EU antitrust fine imposed on U.S. chipmaker Qualcomm, revising it down slightly to $265.5 million from an initial $2.7 million.
The European Commission imposed the fine in 2019, saying that Qualcomm sold its chipsets below cost between 2009 and 2011, in a practice known as predatory pricing, to thwart British phone software maker Icera, which is now part of Nvidia Corp.
Qualcomm had argued that the 3G baseband chipsets singled out in the case accounted for just 0.7% of the Universal Mobile Telecommunications System (UMTS) market and so it was not possible for it to exclude rivals from the chipset market.
The Court made “a detailed examination of all the pleas put forward by Qualcomm, rejecting them all in their entirety, with the exception of a plea concerning the calculation of the amount of the fine, which it finds to be well founded in part,” the Luxembourg-based General Court said.
Qualcomm can appeal on points of law to the EU Court of Justice, Europe’s highest.
The chipmaker did not immediately reply to an emailed Reuters request for comment.
The company convinced the same court two years ago to throw out a $1.1 billion antitrust fine handed down in 2018 for paying billions of dollars to Apple from 2011 to 2016 to use only its chips in all its iPhones and iPads in order to block out rivals such as Intel Corp.
The EU watchdog subsequently declined to appeal the judgment.
