Land mines and tuberculosis are no match for Tanzanian ‘hero rats’ sniffing out danger and disease
  • For decades APOPO has trained these “hero rats,” which have one of the most sensitive noses in the animal kingdom
  • Since 2003, the rats have been finding land mines and, more recently, have been turned on to trafficked wildlife and earthquake survivors

MOROGORO: A man lies unmoving, slumped in the rubble of a simulated earthquake, as an unlikely rescuer approaches: a rat with a backpack. Whiskers waving, the rat breezes past garbage, toppled furniture and scattered clothes to find him and pull a trigger on its pack, alerting searchers above.
Then a resounding click. A survivor has been found. The search in Morogoro in Tanzania’s Uluguru Mountains is over and the rat scurries out of the abandoned building to be rewarded with a banana. A successful mission is complete for this African giant pouched rat being trained for search and rescue operations.
“Their sense of smell is incredible,” said Fabrizio Dell’Anna, an animal behaviorist at APOPO, a Tanzania-based nongovernmental organization that trains the rats for lifesaving applications. “These rats are able to detect explosives, tuberculosis — even tiny amounts of the bacteria — and in this project, they are able to correctly identify and indicate humans.”
In a field nearby, more rats walk on leashes held between handlers, pacing a grid filled with land mines as part of an initiative by APOPO, which works alongside Sokoine University of Agriculture. When they pause, it indicates that explosives are beneath. These rats are readying for their next deployment, perhaps Angola or Cambodia, where APOPO has helped clear more than 50,000 land mines since 2014.
From detecting land mines to sniffing out tuberculosis, these “hero rats” have become unlikely, and sometimes unrecognized, front-line responders in Tanzania and beyond.
Trained ‘hero rats’ with sensitive noses
For decades APOPO has trained these “hero rats,” which have one of the most sensitive noses in the animal kingdom. Since 2003, the rats have been finding land mines and, more recently, have been turned on to trafficked wildlife and earthquake survivors.
The rats begin training shortly after birth for specific missions and, with a longer-than-average rodent life span of almost a decade, can spend years carrying out their work. The cost of training each rat runs around 6,000 euros ($6,990).
It is all done with classical conditioning and positive reinforcement, explained Dell’Anna, who oversees the search and rescue program. The first cohort of this group of specialized rats are already in Turkiye with a partner search and rescue organization.
Helping the global fight against TB
While the rats focused on explosives or survivors buried in rubble get all the glory, it is a group of rats inside a lab that are arguably the most impactful lifesavers. These are not typical lab rats, but rather, as their proponents would argue, one of the world’s most effective detectors of tuberculosis.
“Every day as many people die from TB as from land mines in a whole year,” said Christophe Cox, the CEO of APOPO. “It’s more spectacular to be on the minefield … but for TB … in terms of social impact, it’s tremendous.”
Tuberculosis is an ancient respiratory disease that continues to run rampant despite centuries of research and treatment. The World Health Organization said last October in its most recent TB report that the disease had resurged as the top infectious disease killer, with 1.25 million deaths and a record 8.2 million infections in 2023.
In sub-Saharan Africa, only about half of TB patients receive a diagnosis, according to a study by researchers in the UK and Gambia published in the National Library of Medicine, and this leaves them liable to spread the disease. Tanzania struggles with one of the highest global TB burdens, according to the WHO.
APOPO expanded into TB detection in 2007 and its rats have been deployed in Tanzania, Ethiopia and Mozambique. The group works with 80 hospitals in Tanzania, collecting samples daily and bringing them to the lab rats.
With their sensitive noses, the rats sniff out samples of sputum from patients, looking for positive TB cases that had been marked as negative. Research suggests the rats are picking up on six unique volatile organic compounds in positive TB samples, said Cox.
False negatives remain a persistent issue in TB detection and suppression because each infected person can spread the disease to 10 to 15 more people each year.
“The benefits of using rats are significant,” said Felista Stanesloaus, a doctor at a TB clinic in Morogoro. “They help us detect cases that might otherwise be missed, which prevents people from unknowingly spreading infections.”
Making TB detection accessible
TB detection has made significant advances in recent years, including using artificial intelligence tools in conjunction with lung scans. However, many areas that are burdened most by TB, such as rural villages or low-income urban communities, do not have access to these tools.
While the use of molecular detection devices, such as one called GeneXpert, have become more widespread, a clinic may only have one of these devices and it can take two hours to process a sample. Overburdened clinics turn to the centuries-old technique of microscopy, or investigation of sputum under a microscope, which is both fallible and time-consuming.
“Human error may result in a person being told they are disease-free when they are not,” said Stanesloaus. “Using rats is a very effective initiative.”
APOPO’s rats can scan 100 samples in 20 minutes, and since the program’s inception, the rats have been able to identify more than 30,000 patients who had been sent home with a clean bill of health but were actually carrying TB, said Cox. The NGO is able to do with one lab what 55 hospitals do in a day, he adds.
Yet using live animals in the place of medical devices poses challenges, especially when it comes to scale. Samples have to be brought directly to a lab with enough trained rats to conduct the detection, with some samples brought to Morogoro by motorbike each day. Operations are most effective in dense urban centers, like Dar es Salaam, Cox said.
Meeting WHO standards
The more existential challenge for these “hero rats” comes from regulators and a wider health community who doubt this unconventional method of disease detection.
APOPO’s rats are not classified as primary diagnostic tools by the WHO. Instead, they are a second line of defense. Any positive samples detected by the rats must be confirmed with human microscopy in APOPO’s labs before treatment can be administered.
“It’s a big challenge,” said Cox. “Not being recognized by the WHO means that the mainstream funding for TB … never reaches us.”
Cox has given up on the prospect of getting approval from the WHO, though APOPO has faced pressure from donors to go through this process, which would be extensive and rigorous with no guarantee of success.
Regulators may also challenge APOPO’s method of focusing on finding every single positive case possible at the cost of more potential false positives.
APOPO relies on the indication of just one rat to proceed with further investigation into a possible positive case, while higher specificity standards may need multiple rats to flag a sample.
Cox defends this approach.
“Our choice was to go for that last patient out there — to go for the social impact,” said Cox.

  • Investigators searched his car and deemed it to be safe

WASHINGTON: A man was taken into custody late Tuesday after driving his car into a security barrier outside the White House, authorities said.
The US Secret Service said the man crashed into the security gate at a White House entrance at 10:37 p.m. on Tuesday.


The man was immediately arrested by officers from the Secret Service’s uniformed division, the agency said.
Investigators searched his car and deemed it to be safe, Secret Service officials said in a statement.
The man, whose name wasn’t immediately released, was taken to a hospital for a mental health evaluation, according to a Secret Service spokesperson.
He is expected to be charged with unlawful entry and destruction of government property, the spokesperson said.

  • “Young children can have up to 10 respiratory viruses a year as their immune systems are introduced to different infections for the first time,” said Dr. Goldman, a pediatrician
  • Preventing illness in children at school or at home can be tough, experts acknowledge

BEIRUT: Forget colorful leaves. Any caregiver knows that the real signs of fall are kids with coughs, sneezes and sniffles.
Autumn marks the start of respiratory virus season, when colds, flu and other bugs start circulating — especially among the very young.
A recent study confirmed what many families intuitively know: The littlest students harbor the most germs.
Children in pre-kindergarten and elementary school showed highest rates of virus detection compared with older students and staff, according to research published in the journal Pediatrics.
“Young children can have up to 10 respiratory viruses a year as their immune systems are introduced to different infections for the first time,” said Dr. Jennifer Goldman, a pediatrician at Children’s Mercy hospital in Kansas City, Missouri, who co-led the study.
Younger kids were more likely to have virus detected
Goldman and her colleagues analyzed nasal swabs and symptom reports from more than 800 students and staff in a large school district in Kansas City from November 2022 to May 2023.
They found that overall, more than 85 percent of all participants had at least one respiratory virus detected during that time and more than 80 percent had an episode of acute respiratory illness — though not necessarily at the same time.
More telling, 92 percent of pre-K and elementary school kids had a virus detected, compared with about 86 percent of middle school students, about 77 percent of high school students and 76 percent of staff.
The pre-K kids, ages 3 to 5, had the highest rates of actual illness, too, the study found.
Most of the viruses were the kinds that cause the common cold, including rhinovirus, which was found in 65 percent of participants, and types of seasonal coronavirus detected in about 30 percent. The virus that causes COVID-19 was found in about 15 percent of those studied.
Study confirms the experiences of pediatricians who are parents
The new study provides a baseline look at the burden of viruses in school settings, Goldman said.
It also confirms the real-world experience of pediatricians who are parents, like Dr. Nicole Torres of the University of Miami Health System.
“I can say this for my own children, who are now in their teens: They were sicker when they were younger,” she said.
The study also squares with older research that found that young kids play a key role in spreading respiratory viruses at home. Dr. Carrie Byington was co-author of a University of Utah study, published in 2015, that recruited 26 households to take nasal samples from everyone living in a home, every week, for a year.
That study found that children younger than 5 had virus detected for half of the weeks of the year, recalled Byington, who is now with the University of California, San Diego.
“And if you live in a household with multiple children, that proportion just goes higher, so it can appear as if someone is always sick,” she said.
How to prevent illness — or at least try to
Preventing illness in children at school or at home can be tough, experts acknowledge.
Being up to date on vaccinations for COVID-19 and influenza is important, they said. So is frequent handwashing, learning to cover coughs and keeping hands away from the eyes, nose and mouth. Cleaning and sanitizing frequently touched surfaces and objects and optimizing fresh air are also key.
When little ones do get sick, the best treatment is often supportive care like extra fluids and rest. In serious cases, medical providers may recommend medications to reduce fever or antiviral drugs.
It can take a couple weeks, however, for lingering symptoms like coughs to completely resolve. By then, the child may well have another cold.
“I do tell parents of younger children to expect them to be ill once every month, every month and a half,” Torres said. “It’ll seem that way.”

  • The Russian maneuvers come with efforts faltering to solve the Ukraine war
  • Russia’s drill involved a mock intercontinental ballistic missile launch from a submarine in the Barents Sea

MOSCOW: Russia held planned strategic nuclear drills on Wednesday, a week after NATO began similar annual exercises, as tensions in Europe over the Ukraine war run high.
“Today we are conducting planned, I would like to emphasize, planned, nuclear forces training,” Russian President Vladimir Putin told generals in a televised meeting.
NATO began similar annual nuclear exercises focused on the North Sea region last Monday.


The Russian maneuvers come with efforts faltering to solve the Ukraine war, and after US President Donald Trump on Tuesday shelved planned peace talks with Putin.
Russia’s drill involved a mock intercontinental ballistic missile launch from a submarine in the Barents Sea, next to the Western bloc’s borders.
Another mock rocket was launched from a cosmodrome in northern Russia, while strategic bombers carried out air missile strikes, the Russian military said.
Videos released by the Russian Ministry of Defense showed the launches from ground, sea and aerial carriers.
Russia’s recent air incursions in Poland and Estonia, and a string of unexplained drone flights, have rattled NATO members and renewed calls to beef up the alliance’s defense.
Ukrainian President Volodymyr Zelensky failed to secure US long-range Tomahawk missiles on his last visit to Washington, despite weeks of calling for them.
Moscow has repeatedly criticized potential supplies of the nuclear-capable missiles, promising a serious escalation if they were to become reality.

A Cuban man deported by the US to Africa is on a hunger strike in prison, his lawyer says
  • “My client is arbitrarily detained, and now his life is on the line,” David said
  • Civic groups in Eswatini have also taken authorities to court to challenge the legality of holding foreign nationals in prison without charge

CAPE TOWN: A Cuban man deported by the United States to the African nation of Eswatini is on a hunger strike at a maximum-security prison having been held there for more than three months without being charged or having access to legal counsel under the Trump administration’s third-country program, his US-based lawyer said Wednesday.
Roberto Mosquera del Peral was one of five men sent to the small kingdom in southern Africa in mid-July as part of the expanding US deportation program to Africa, which has been criticized by rights groups and lawyers, who say deportees are being denied due process and exposed to rights abuses.
Mosquera’s lawyer, Alma David, said in a statement sent to The Associated Press that he had been on a hunger strike for a week, and there were serious concerns over his health.
“My client is arbitrarily detained, and now his life is on the line,” David said. “I urge the Eswatini Correctional Services to provide Mr. Mosquera’s family and me with an immediate update on his condition and to ensure that he is receiving adequate medical attention. I demand that Mr. Mosquera be permitted to meet with his lawyer in Eswatini.”
An Eswatini government spokesperson referred the AP, which requested comment, to a correctional services official, who didn’t immediately respond to calls and messages.
Mosquera was among a group of five men from Cuba, Jamaica, Laos, Vietnam and Yemen deported to Eswatini, an absolute monarchy ruled by a king who is accused of clamping down on human rights. The Jamaican man was repatriated to his home country last month, but the others have been kept at the prison for more than three months, while an Eswatini-based lawyer has launched a case against the government demanding they be given access to legal counsel.
Civic groups in Eswatini have also taken authorities to court to challenge the legality of holding foreign nationals in prison without charge. Eswatini said that the men would be repatriated, but have given no timeframe for any other repatriations.
US authorities said they want to deport Kilmar Abrego Garcia to Eswatini under the same program.
The men sent to Eswatini were criminals convicted of serious offenses, including murder and rape, and were in the US illegally, the US Department of Homeland Security said. It said that Mosquera had been convicted of murder and other charges and was a gang member.
The men’s lawyers said they had all completed their criminal sentences in the US, and are now being held illegally in Eswatini, where they haven’t been charged with any offense.
The US Department of Homeland Security has cast the third-country deportation program as a means to remove “illegal aliens” from American soil as part of US President Donald Trump’s immigration crackdown, saying they have a choice to self-deport or be sent to a country like Eswatini.
The Trump administration has sent deportees to at least three other African nations — South Sudan, Rwanda and Ghana — since July under largely secretive agreements. It also has a deportation agreement with Uganda, although no deportations there have been announced.
New York-based Human Rights Watch said that it has seen documents that show that the US is paying African nations millions of dollars to accept deportees. It said that the US agreed to pay Eswatini $5.1 million to take up to 160 deportees and Rwanda $7.5 million to take up to 250 deportees.
Another 10 deportees were sent to Eswatini this month and are believed to be held at the same Matsapha Correctional Complex prison outside the administrative capital, Mbabane. Lawyers said that those men are from Vietnam, Cambodia, the Philippines, Cuba, Chad, Ethiopia and Congo.
Lawyers say the four men who arrived in Eswatini on a deportation flight in July haven’t been allowed to meet with an Eswatini lawyer representing them, and phone calls to their US-based attorneys are monitored by prison guards. They have expressed concern that they know little about the conditions in which their clients are being held.
“I demand that Mr. Mosquera be permitted to meet with his lawyer in Eswatini,” David said in her statement. “The fact that my client has been driven to such drastic action highlights that he and the other 13 men must be released from prison. The governments of the United States and Eswatini must take responsibility for the real human consequences of their deal.”

A major Russian drone and missile attack on Ukraine kills at least 6 people, officials say
  • Repeated waves of missiles and drones throughout the night targeted at least eight Ukrainian cities
  • Russian drones also hit a kindergarten in Kharkiv during the day Wednesday when children were in the building

KYIV: A large-scale Russian drone and missile attack across Ukraine killed at least six people, including a woman and her two young daughters, officials said Wednesday, as US-led efforts to end the war floundered and Ukraine’s president sought more foreign military help.
Repeated waves of missiles and drones throughout the night targeted at least eight Ukrainian cities, as well as a village in the Kyiv region where a strike set fire to a house in which the mother and her 6-month and 12-year-old daughters were staying, regional head Mykola Kalashnyk said.
At least 25 people, including five children, were injured in Kyiv alone, authorities said.

Russian drones also hit a kindergarten in Kharkiv, Ukraine’s second-largest city, during the day Wednesday when children were in the building, Mayor Ihor Terekhov said. One person was killed and six were injured but no children were physically harmed, he said.
Even so, Ukrainian President Volodymyr Zelensky said many of the children were in shock after being rescued from the building by emergency crews.
Russia fired 405 strike and decoy drones and 28 missiles at Ukraine, mainly targeting Kyiv, Ukraine’s air force said.
Peace efforts mark time
US President Donald Trump ‘s efforts to end the war that started with Russia’s all-out invasion of its neighbor more than three years ago have failed to gain traction. Trump has repeatedly expressed frustration with Russian President Vladimir Putin’s refusal to budge from his conditions for a settlement after Ukraine offered a ceasefire and direct peace talks.
Trump said Tuesday that his plan for a swift meeting with Putin was on hold because he didn’t want it to be a “waste of time.” European leaders accused Putin of stalling. Zelensky said Wednesday that Trump’s proposal to freeze the conflict where it stands on the front line “was a good compromise” — a step that could pave the way for negotiations.
Kremlin spokesman Dmitry Peskov said Wednesday that the planned summit requires careful preparation, suggesting that laying the groundwork could be protracted. “No one wants to waste time: neither President Trump nor President Putin,” he said. “These are the two presidents who are accustomed to working efficiently with high productivity.”
Zelensky urged the European Union, the United States, and the Group of Seven industrialized nations to heap more pressure on Russia and force it to the negotiating table.
Pressure can be applied on Moscow “only through sanctions, long-range (missile) capabilities, and coordinated diplomacy among all our partners,” he said.
Zelensky credited Trump’s remarks that he was considering supplying Tomahawk missiles to Ukraine for Putin’s willingness to meet.
Russia has not made significant progress on the battlefield where a war of attrition has taken a high toll on Russian infantry and Ukraine is short of manpower, military analysts say. Meanwhile, both sides have invested in long-range strike capabilities to hit rear areas.
Ukraine says it hit a key Russian chemical plant
Ukraine’s army general staff said the country’s forces struck a chemical plant in Russia’s Bryansk region on Tuesday night using British-made air-launched Storm Shadow missiles. The plant is an important part of the Russian military and industrial complex producing gunpowder, explosives, missile fuel and ammunition, it said.
Russian officials in the region confirmed an attack but did not mention the plant.
Russia’s Defense Ministry said its air defenses downed 33 Ukrainian drones over several regions overnight, including the area around St. Petersburg. Eight airports temporarily suspended flights overnight because of the attack.
Zelensky arrived Wednesday in Oslo, Norway, and after that flew to Stockholm, where he is expected to meet with Swedish Prime Minister Ulf Kristersson at the start of what the Ukrainian leader has said will be a week of intense diplomacy.
More international economic sanctions on Russia are likely to be discussed at an EU summit in Brussels on Thursday. On Friday, a meeting of the Coalition of the Willing — a group of 35 countries who support Ukraine — is to take place in London.
Also Wednesday, Trump is expected to hold talks at the White House with NATO Secretary-General Mark Rutte. The military alliance has been coordinating deliveries of weapons to Ukraine, many of them purchased from the United States by Canada and European countries.
Russia’s long barrage
Moscow’s attack, which began overnight and extended into Wednesday morning, also targeted energy infrastructure and caused rolling blackouts, officials said. Russia has been trying to cripple the country’s power grid before the bitter winter sets in.
In Kyiv, residents reeled from the drone and missile bombardment.
“We heard a loud explosion and then the glass started to shatter, and then everything was caught up in a burst of fire, the embers were everywhere,” Olena Biriukova, a 58-year-old living in an apartment building told The Associated Press.
“It was very scary for kids,” she said. “I never thought that this could happen in our neighborhood.”
Zelensky said the Russian attack targeted the wider Kyiv, Odesa, Chernihiv, Dnipropetrovsk, Kirovohrad, Poltava, Vinnytsia, Zaporizhzhia, Cherkasy, and Sumy — 10 regions in all.
Two more people were found dead in the Dnipro district of the Ukrainian capital, where emergency services rescued 10 people after a fire caused by drone debris hit the sixth floor of a 16-story residential building, local authorities said.
And in Kyiv’s Darnytskyi district emergency services were responding after drone debris hit a 17-story residential building causing a fire on five floors. Fifteen people had to be rescued, including two children.
