The technology fighting Rwanda’s silent killer of women

Cervical cancer is the most commonly diagnosed cancer affecting women in Rwanda
Share this:

When Rwandan villager Lillian was diagnosed with cervical cancer, the 30-year-old feared that her life was over. But a new gadget aimed at patients in low-income countries offered her hope.

“The medical diagnosis was very scary; my husband couldn’t believe it,” Lillian — not her real name — told AFP.

“We had heard of people dying of cancer and that it was incurable, so it was a very scary moment.” 

Her fears were not unfounded.

Cervical cancer is a notorious “silent killer” of women, but especially so in poor countries that lack affordable treatment and diagnostics.

In Rwanda, it is the most commonly diagnosed cancer, attacking 42 out of every 100,000 women, three times the global average, according to national statistics.

The stigma and fear surrounding the disease and its connection to HIV — a major risk factor for cervical cancer — means many Rwandan women are reluctant even to get tested.

And those who are diagnosed often assume that treatment is out of bounds, unless they live in a major city. 

For Lillian, whose village is a three-hour drive east of the capital Kigali, the likelihood of emerging cancer-free, less than four months after diagnosis, seemed like a fantasy.

But in 2020, Rwanda decided to trial a portable device that treats precancerous lesions with heat and can be used in countries with limited access to advanced equipment or facilities.

“The nurse who treated me used a small gadget that looked like a gun. It is uncomfortable but not painful, even when it uses heat to kill the cancer lesions,” Lillian said.

– Energy-efficient solution –

The so-called C3 thermocoagulator is a pistol-like probe that uses battery power, meaning it can be deployed in remote areas without 24/7 access to electricity.

“The device works by applying heat to the cervix, which causes the abnormal cells to die,” Christine Musabyeyezu, a nurse at Kigali’s Remera health centre, told AFP.

Aimed at being a cost-effective alternative to cryotherapy, the traditional technology used in the treatment of cervical cancer, the device is simple to use, requiring minimal training for health workers, she said.

“At first we relied on cryotherapy to treat cervical cancer lesions, but this method is complicated, expensive and not easily accessible across the country,” Musabyeyezu said.

Cryotherapy, which applies a probe to the cervix to freeze lesions, utilises a lot of energy to ensure that the probe is cold enough.

The thermal devices on the other hand are energy-efficient, offering a week’s worth of use (around 140 treatments) before requiring a recharge.

The gadgets are now at the epicentre of Rwanda’s fight against cervical cancer, particularly in rural areas.

The Central African nation is among seven sub-Saharan countries that have adopted the device, made by a German company, WISAP Medical Technology. 

– ‘Test early, treat early’ –

Health workers in Rwanda are also hopeful that the success of C3 will go hand-in-hand with a potential breakthrough in diagnostics.

Highly diluted acetic acid — vinegar — has become an established method for spotting pre-cancerous lesions on the cervix, which turn white in the presence of the substance.

However, human interpretation of the test can vary, which is where a mobile app powered by artificial intelligence comes in, boosting accuracy as well as speed.

According to Marisol Touraine, president of the international health agency Unitaid, which is supporting medical trials of the app in Rwanda, more than 300,000 women lose their lives to cervical cancer every year. 

The vast majority of these deaths — a staggering 90% — occur in low-income countries “because they were not screened in time, because they were not treated in time,” Touraine told AFP.

The increase in the number of women coming forward to get tested in Rwanda is good news, said nurse Musabyeyezu.

“There is always a queue here of women coming to test for cervical cancer, more than for any other medical tests,” she said.

“This is a good thing because when they test early they can be treated early.”

In Brazil, hopes to use AI to save wildlife from roadkill fate

Published

Some 475 million vertebrate animals die on Brazilian roads every year
Share this:

In Brazil, where about 16 wild animals become roadkill every second, a computer scientist has come up with a futuristic solution to this everyday problem: using AI to alert drivers to their presence.

Direct strikes on the vast South American country’s extensive road network are the top threat to numerous species, forced to live in ever-closer proximity with humans.

According to the Brazilian Center for Road Ecology (CBEE), some 475 million vertebrate animals die on the road every year — mostly smaller species such as capybaras, armadillos and possums.

“It is the biggest direct impact on wildlife today in Brazil,” CBEE coordinator Alex Bager told AFP.

Shocked by the carnage in the world’s most biodiverse country, computer science student Gabriel Souto Ferrante sprung into action.

The 25-year-old started by identifying the five medium- and large-sized species most likely to fall victim to traffic accidents: the puma, the giant anteater, the tapir, the maned wolf and the jaguarundi, a type of wild cat.

Souto, who is pursuing a master’s degree at the University of Sao Paulo (USP), then created a database with thousands of images of these animals, and trained an AI model to recognize them in real time.

Numerous tests followed, and were successful, according to the results of his efforts recently published in the journal Scientific Reports.

Souto collaborated with the USP Institute of Mathematical and Computer Sciences.

For the project to become a reality, Souto said scientists would need “support from the companies that manage the roads,” including access to traffic cameras and “edge computing” devices — hardware that can relay a real-time warning to drivers like some navigation apps do.

There would also need to be input from the road concession companies, “to remove the animal or capture it,” he told AFP.

It is hoped the technology, by reducing wildlife strikes, will also save human lives.

– ‘More roads, more vehicles’- 

Bager said a variety of other strategies to stop the bloodshed on Brazilian roads have failed.

Signage warning drivers to be on the lookout for crossing animals have little influence, he told AFP, leading to a mere three-percent reduction in speed on average.

There are also so-called fauna bridges and tunnels meant to get animals safely from one side of the road to the other, and fences to keep them in — all insufficient to deal with the scope of the problem, according to Bager.

In 2014, he created an app called Urubu with other ecologists, to which thousands of users contributed information, allowing for the identification of roadkill hotspots.

The project helped to create public awareness and even inspired a bill on safe animal crossing and circulation, which is awaiting a vote in Congress. 

A lack of money saw the app being shut down last year, but Bager is intent on having it reactivated.

“We have more and more roads, more vehicles and a number of roadkill animals that likely continues to grow,” he said.

Honda to build major EV plant in Canada: govt source

Honda hopes to sell only zero-emission vehicles by 2040, with a goal of going carbon-neutral in its own operations by 2050

Japanese auto giant Honda will open an electric vehicle plant in eastern Canada, a Canadian government source familiar with the multibillion-dollar project told AFP on Monday.

The federal government as well as the province of Ontario, where the plant will be built, will both provide some financial incentives for the deal, according to the source, who spoke on condition of anonymity.

The official announcement is due Thursday, though Ontario premier Doug Ford hinted at the deal on Monday.

“This week, we’ve landed a new deal. It will be the largest deal in Canadian history. It’ll be double the size of Volkswagen,” he said, referring to a battery plant announced last year, for which the German automaker pledged Can$7 billion (US$5 billion) in investment.

Canada in recent years has been positioning itself as an attractive destination for electric vehicle investment, touting tax incentives, renewable energy access and its rare mineral deposits.

The Honda plant, to be built an hour outside Toronto, in Alliston, will also produce electric-vehicle batteries, joining existing Volkswagen and Stellantis battery plants.

In January, when news of the deal first bubbled up in the Japanese press, the Nikkei newspaper estimated it would be worth Can$14 billion — numbers backed up by Canadian officials recently.

In the federal budget announced last week, Prime Minister Justin Trudeau’s government introduced a new business tax credit, granting companies a 10 percent rebate on construction costs for new buildings used in key segments of the electric vehicle supply chain.

Canada’s strategy follows that of the neighboring United States, whose Inflation Reduction Act has provided a host of incentives for green industry.

Honda hopes to sell only zero-emission vehicles by 2040, with a goal of going carbon-neutral in its own operations by 2050.

Denmark launches its biggest offshore wind farm tender

Denmark's offshore wind parks currently generate 2.7 gigawatts of electricity
Share this:

The Danish Energy Agency on Monday launched its biggest tender for the construction of offshore wind farms, aimed at producing six gigawatts by 2030 — more than double Denmark’s current capacity.

Offshore wind is one of the major sources of green energy that Europe is counting on to decarbonise electricity production and reach its 2050 target of net zero carbon production, but it remains far off the pace needed to hit its targets.

Denmark’s offshore wind parks currently generate 2.7 gigawatts of electricity, with another one GW due in 2027.

The tender covers six sites in four zones in Danish waters: North Sea I, Kattegat, Kriegers Flak II and Hesselo.

“We are pleased that we can now offer the largest offshore wind tender in Denmark to date. This is a massive investment in the green transition,”  Kristoffer Bottzauw, head of the Danish Energy Agency, said in a statement.

Investment in offshore wind plummeted in Europe in 2022 due to supply chain problems, high interest rates and a jump in prices of raw materials, before bouncing back in 2023.

A record 4.2 gigawatts was installed in Europe last year, when a record 30 billion euros in new projects were approved, the trade association WindEurope said in January.

It said it was optimistic about the future of offshore wind in Europe, expecting new offshore wind capacity of around five gigawatts per year for the next three years.

However, it noted that that was still far short of what is needed if Europe wants to hit its 2030 target of 111 gigawatts of offshore wind installed capacity, with less than 20 gigawatts installed at the end of 2023.
