Home Office Acknowledges Issues with Facial Recognition Technology for Black and Asian Individuals

Ministers are under pressure to implement more robust safeguards for facial recognition technology, as the Home Office has acknowledged that it may mistakenly identify Black and Asian individuals more frequently than white people in certain contexts.

Recent tests conducted by the National Physical Laboratory (NPL) on how this technology functions within police national databases revealed that “some demographic groups are likely to be incorrectly included in search results,” according to the Home Office.

The Police and Crime Commissioner stated that the release of the NPL’s results “reveals concerning underlying bias” and urged caution regarding plans for a nationwide implementation.

These findings were made public on Thursday, shortly after Police Minister Sarah Jones characterized the technology as “the most significant advancement since DNA matching.”

Facial recognition technology analyzes individuals’ faces and cross-references the images against a watchlist of known or wanted criminals. It can be employed to scrutinize live footage of people passing in front of cameras, match faces with wanted persons, or assist police in targeting individuals on surveillance.

Images of suspects can be compared against police, passport, or immigration databases to identify them and review their backgrounds.

Analysts who evaluated the Police National Database’s retrospective facial recognition tool at lower settings discovered that “white subjects exhibited a lower false positive identification rate (FPIR) (0.04%) compared to Asian subjects (4.0%) and Black subjects (5.5%).”

Further testing revealed that Black women experienced notably high false positives. “The FPIR for Black male subjects (0.4%) is lower than that for Black female subjects (9.9%),” the report detailed.

The Police and Crime Commissioners Association stated that these findings reflect internalized bias. “This indicates that, in certain scenarios, Black and Asian individuals are more prone to incorrect matches than their white counterparts. Although the terminology is technical, it is evident that this technology is being integrated into police operations without adequate safeguards,” the report noted.

The statement, signed by APCC leaders Darryl Preston, Alison Rowe, John Tizard, and Chris Nelson, raised concerns why these findings were not disclosed sooner and shared with Black and Asian communities.

The report concluded: “While there is no evidence of adverse effects in individual cases, this is due to chance rather than a systematic approach. System failures have been known for a while, but the information was not conveyed to the communities impacted and key stakeholders.”

The government has initiated a 10-week public consultation aimed at facilitating more frequent usage of the technology. The public will be asked if police should have permission to go beyond records and access additional databases, such as images from passports and driving licenses, to track criminals.

Civil servants are collaborating with police to create a new national facial recognition system that will house millions of images.

Charlie Welton, head of policy and campaigns at Liberty, stated: “The racial bias indicated by these statistics demonstrates that allowing police to utilize facial recognition without sufficient safeguards leads to actual negative consequences. There are pressing questions regarding how many individuals of color were wrongly identified in the thousands of monthly searches utilizing this biased algorithm and the ramifications it might have.”

“This report further underscores that this powerful and opaque technology cannot be deployed without substantial safeguards to protect all individuals, which includes genuine transparency and significant oversight. Governments must halt the accelerated rollout of facial recognition technology until protections are established that prioritize our rights, aligning with public expectations.”

Former cabinet minister David Davis expressed worries after police officials indicated that cameras could be installed at shopping centers, stadiums, and transport hubs to locate wanted criminals. He told the Daily Mail: “Brother, welcome to the UK. It is evident that the Government is implementing this dystopian technology nationwide. There is no way such a significant measure could proceed without a comprehensive and detailed discussion in the House of Commons.”

Officials argue that the technology is essential for apprehending serious criminals, asserting that there are manual safeguards embedded within police training, operational guidelines, and practices that require trained personnel to visually evaluate all potential matches derived from the police national database.

A Home Office representative said: “The Home Office takes these findings seriously and has already acted. The new algorithm has undergone independent testing and has shown no statistically significant bias. It will be subjected to further testing and evaluation early next year.”

“In light of the significance of this issue, we have requested the Office of the Inspector General and the Forensic Regulator to review the application of facial recognition by law enforcement. They will evaluate the effectiveness of the mitigation measures, and the National Council of Chiefs of Police backs this initiative.”

New Fossil Discoveries Indicate Asian Forest Tortoise Ancestors Evolved in Europe

Paleontologists from the Institute of Paleontology of the Polish Academy of Sciences and the Autonomous University of Barcelona have identified a new species within the genus Turtle, known as Manuria. This discovery is based on fossilized remains found in the Czech Republic.

Manulia morula thrived in the wetlands of what is now the Czech Republic during the early Miocene epoch, roughly 20 to 17 million years ago.

This species is recognized as the oldest member of Manuria, which currently exists solely in Southeast Asia and comprises four extinct species along with two living ones: Manulia Emmis and the impressed turtle (Manulia Impreza).

Tortoise paleontologist Dr. Milan Kraust from the Institute of Paleontology of the Polish Academy of Sciences remarked, ‘Turtles of the family Testudinidae are a clade highly specialized for terrestrial environments, predominantly inhabiting semi-arid conditions.’

“Members of the Testudinidae family, with carapace lengths ranging from 35 to 75 cm (14 to 30 inches), are categorized as medium to large-sized turtles, while those exceeding 75 cm are classified as giant-sized turtles.”

“Extant species of the Testudinidae can be divided into three main groups: gophers and Manuria (which appears as a basal genus or continuous branch), geokerona clade, and test duna clade, with the latter two forming the subfamily Testudininae.”

The fossil remains of Manulia morula include parts of the carapace and plastron, along with numerous unidentified shell fragments, which were uncovered at the Arnikov I fossil site in the Most Basin of Bohemia.

The length of the turtle’s shell is estimated to have been around 50 cm (20 inches).

“The Anikov I area has long been recognized as a region where wetlands featuring flooded rivers and shallow lakes have been documented,” the paleontologists stated.

“The wetland habitat near the coast was also inferred from the abundance of juvenile crocodiles and potentially the presence of Coristodere.”

“However, based on research findings regarding this genus, Manuria suggests a humid forest of evergreen broad-leaved trees situated near water, characterized by a rainy season and a distinct drier, cooler season, reminiscent of the current Kaeng Krachan National Park in Thailand.”

The discovery of Manulia morula broadens the paleobiogeographical distribution of this genus, Manuria, extending its range from Asia into the heart of Europe.

“According to our findings, the genus Manuria originated in Europe just prior to the Miocene climate optimum, subsequently spreading to Asia, where it continues to thrive today,” the researchers elaborated.

These findings were published on October 3, 2025, in the Swiss Journal of Paleontology.

Deceived and Defeated: The Struggles of African Job Seekers Exploited by Asian Cyber Scammers

WAfter arriving in Bangkok from Nairobi last December, Duncan Okindo sensed something was amiss as he began his job as a customer service agent. The 26-year-old had previously sold cattle, borrowed funds from a friend, and used his savings to pay the recruitment agency 200,000 Kenyan Shillings (£1,150).

“I thought it was a positive step to leave [the country] and seek opportunities to support my family,” Okindo recalls.

Unfortunately, when a van collected Okindo and six other Kenyans at the airport, the driver took their passports and falsely informed Thai officials that they were tourists. After several hours of travel, they were taken to a boat to cross a river, confused and exhausted.

They were then taken to Myanmar. Walled compounds guarded by rebel militias awaited them.

For the next three months, he was forced to send thousands of messages from fake social media accounts, posing as a wealthy American investor to defraud U.S. real estate agents through cryptocurrency scams.

When he failed to hit his daily targets, he faced beatings, confinement in a freezing room, and sometimes went without food for up to two days. He prayed for the safety of others who suffered at the hands of the Chinese gangsters operating the center, wishing they could avoid the electrocution and sexual torture he witnessed.

“It was hell on Earth,” says Okindo. “I felt completely shattered.”

Eventually, he was released from Myanmar’s KK Park, a compound reflecting the rising number of Kenyans, Ugandans, and Ethiopians trafficked to Southeast Asia as criminal organizations look to expand the East African labor pool.

Since the 2021 coup in Myanmar, there’s been a surge in cyber slavery compounds, taking advantage of the country’s weakened governance and fostering illegal activities. The number of such centers along the Thai border has escalated from 11 to 26 in just four years.

The United Nations estimates that at least 120,000 individuals are trapped in cyberscam compounds, and human trafficking experts and rescue organizations in Myanmar have noted that crackdowns have yielded minimal results. These centers are often run by Chinese criminal gangs, with some colluding with Myanmar’s military along the borders.

Okindo considers himself fortunate. The mission to find and free trafficked individuals involves coordination among multiple governments, militias, and police forces. Thai officials have successfully promoted the release of thousands of trafficking victims, while East African governments are increasingly collaborating with Thai authorities willing to engage with Myanmar’s junta and militia forces at the border.

Victims can only be released into Thai custody if their home country agrees to take responsibility for their repatriation and the associated costs.

Since 2020, the Southeast Asian cyberslavery industry has ensnared hundreds of thousands, forcing individuals into what is colloquially termed “slaughtering the pigs,” a brutal way to build trust with scam targets before executing fraud. Initially aimed at Chinese and Taiwanese victims, the industry has expanded to Southeast Asians, Indians, and now, Africans.




“Sometimes I’m afraid to talk about it,” Okindo reflects. Photo: Provided by Duncan Okindo

The criminal syndicate is shifting focus to fraudulent victims in the U.S. and Europe, with China working to prevent citizens from becoming targets, an expert informed The Guardian.

This has led various human trafficking networks to search for recruits with English and technical skills, including East Africans. Estimates now suggest thousands are trapped in Southeast Asian compounds, according to Benedict Hoffman, a representative of the United Nations Office on Drugs and Crime in Southeast Asia and the Pacific.

As awareness grows among citizens in various countries, recruitment becomes increasingly challenging. “It’s much harder these days to enlist large numbers of individuals from India,” Hoffmann notes. “This is why we’re observing a rise in victims from Africa.”

Between January and April, the Kenyan government successfully repatriated 175 citizens from Myanmar; Roseline Njogu, the Director of the Diaspora Issues Department in Kenya’s State Department, noted that a substantial group of Kenyans, about 150 individuals trafficked from across Southeast Asia, was rescued between 2022 and 2024. This issue also extends to Ethiopia and Uganda.

In Kenya, approximately 80% of the population is under 35, and the unemployment rate is alarmingly high. The government under President William Ruto has actively promoted labor exports. Investigations indicate that four in ten young Kenyans are considering moving abroad.

Recruiters exploiting modern slavery are capitalizing on government migration promotion, targeting Kenya through online job advertisements, social media, texts, and in-person visits to rural areas, states Mutuk Nguri, CEO of the Counter Human Traffic Trust.

The government acknowledges its precarious position, according to Nguri. The Kenyan Ministry of Foreign Affairs and Diaspora Issues did not respond to requests for comments.

Thailand has aided thousands, but repatriation presents its own challenges and costs. Thai officials must establish that workers are indeed victims of human trafficking before releasing them to their home countries.


When Susan Wahura* was rescued from a Myanmar romance scam operation in 2022, she spent a month moving between four Thai detention centers before realizing she was trafficked and initiating legal steps to obtain freedom.

“I spent time in a solitary cell before accepting my status as a trafficking victim which ultimately led to my freedom,” shares 32-year-old Wahura.

Neither Uganda nor Ethiopia maintain embassies in Thailand, complicating their ability to identify victims in Myanmar, currently engulfed in civil conflict. Earlier this year, several Ugandans and Ethiopians found themselves stranded at the Myanmar-Thai border as repatriation efforts stalled.

The fraud syndicate is exploiting vulnerabilities in East Africa’s diplomatic representation to deter victims from seeking help, asserts Jason Tower, a global initiative against transnational organized crime.

“Ultimately, that’s the objective of the scam syndicate—to transform individuals into profit-generating machines, acting as high-capacity con artists,” states Tower.


Nevertheless, despite repatriation efforts by East African nations, deceptive recruitment agencies keep advertising fake job opportunities. Both Okindo and Wahura continue to share guardian messages with Kenyans contemplating moves to Southeast Asia.

In May, Okindo, who holds a mass communication diploma, filed a lawsuit against the recruitment agency and its staff, accusing them of conscription into slavery and human trafficking. A Nairobi court has issued a temporary injunction preventing the overseas employment of labor.

Since his return, Okindo has spoken publicly about his experiences through television, TikTok, and other social media outlets, connecting stranded victims with legal support, aid organizations, and ambassadors for their recovery.

His aim is to raise awareness about malicious institutions and false job opportunities while encouraging victims to seek justice.

“I’ve enlightened many individuals,” he asserts. “Though I sometimes feel scared discussing it, I share my story, knowing that speaking out could help save others.”

New Research Reveals Asian Elephants Have Larger Brains Than Their African Relatives

Elephants are fascinating creatures. Despite their allure, our understanding of the elephant brain remains limited, and there are notable neuroanatomical differences between the Asian (Elephas Maximus) and African elephants (Loxodonta africana), which have largely gone unexplored. In a recent study, researchers from Humboldt Universität in Berlin and the Leibniz Institute for Zoo and Wildlife Research collected numerous elephant brains to investigate the macroanatomical features that differentiate the species. Surprisingly, they found that Asian elephants possess a larger brain and greater grey matter volume than African elephants, an intriguing contrast given the smaller body size of Asian elephants.

“The morphological distinctions among elephant species are well-documented,” stated Dr. Marav Schah from Humboldt Universität Berlin and his colleagues.

“For instance, African savanna elephants are larger and have bigger ears than their Asian counterparts.”

“It is also noted that only female African elephants grow larger tusks compared to the minimal tusks found in Asian females.”

“These disparities indicate significant genetic divergence between savanna elephants in Asia and Africa, believed to have arisen 50,000 to 8 million years ago.”

In this research, the team examined the brain weights and structures of both Asian and African elephants via dissections, existing literature, and MRI scans from wildlife and zoo animals.

The findings revealed that adult Asian elephants are significantly heavier than their African counterparts, whose brains average just over 4,400 grams.

This specific finding could not be definitively validated for male elephants, as data for the brain weights in Asian males is limited.

However, the cerebellum appears proportionately heavier in African elephants (22% of total brain body weight) compared to Asian elephants (19%).

Researchers also demonstrated that elephants undergo extensive postnatal brain growth.

By adulthood, an elephant’s brain is roughly three times heavier than at birth.

This indicates that elephants experience notably more brain growth than all primates; except for humans, where the brain weighs only about one-fifth of its final weight at birth.

“The variance in brain weight is likely the most significant difference among these two elephant species,” Dr. Shah noted.

“This accounts for the behavioral variations observed between elephants in Asia and Africa.”

“For instance, the two species display markedly different interactions with humans.”

“Asian elephants have been partially domesticated for millennia and serve as working animals across various cultures and regions.”

“Conversely, only a handful of cases of partial domestication have been somewhat successful with African elephants.”

“It is considerably harder to integrate an African elephant into human society compared to an Asian elephant.”

The study was published today in the journal pnas nexus.

Google settles $28 million lawsuit for allegedly favoring white and Asian employees

Google has agreed to pay $28 million (£22 million) to settle class action lawsuits by compensating white and Asian employees more and providing them with a higher career track compared to other employees.

The settlement with Alphabet’s Google was preliminarily approved by Judge Charles Adams of Santa Clara County Superior Court in California last week.

Judge Adams described it as “a positive outcome for the class” consisting of at least 6,632 Google employees in California from February 15, 2018 to December 31, 2024.

A Google spokesperson confirmed the settlement, stating, “We refute the allegations of differential treatment and are committed to compensating, hiring, and promoting all our employees fairly.”

The lawsuit was spearheaded by Ana Cantu, who identifies as Mexican and indigenous, on behalf of minority employees at Google from Hispanic, Latino, Indigenous, Native American, and other backgrounds.

Cantu claimed that despite performing exemplary work in Google’s People’s Business and Cloud sector for seven years, she was not compensated or promoted on par with her white and Asian counterparts.

She alleged that Google favored white and Asian employees, placing them in higher “levels” within the company even when performing similar roles as minority employees.

Cantu argued that Google’s actions violated California’s Equal Pay Act, and she left the company in September 2021.

The final settlement amount will be $20 million after deducting legal costs, penalties related to Cantu’s claims under California’s General Civil Attorneys Act, and other expenses totaling $7 million.

Judge Adams has scheduled a hearing in September to review and approve the final settlement. Cantu’s legal representatives have not yet responded to requests for comment.

New research uncovers Asian Hornets preying on nearly 1,500 invertebrate species

Biologist of University of Exeter We conducted the first large-scale study on Asian Hornet diets (Vespa Velutina), exploiting deep sequences to characterize the intestinal content of larvae in Jersey, France, Spain and the UK. European honeybees were the most common species found in the Hornets, but their diet is much broader. The analysis detected 1,449 invertebrate species, increasing the prey abundance of samples from south latitude.

The invasive species of Asian hornets are now found in much of Western Europe.

The nests are destroyed every year in mainland Britain as authorities try to lock out the seeds.

“The University of Exeter has been working hard to understand,” said Dr. Sifreya Pedersen, a researcher at the University of Exeter.

“Diets vary strongly across seasons and regions, indicating that they are highly flexible predators.”

“Most insect populations are reduced due to factors such as habitat destruction and chemical contamination.”

“The expanded areas where the Hornets live in Asia pose an extra threat.”

In this study, Dr. Pedersen and colleagues used a method called deep sequencing to identify the visceral prey species of over 1,500 Asian hornet larvae eating foods offered by adult hornets.

Of the top 50 invertebrate prey species identified, 43 are known to visit flowers. Among these were pollinators of three major European crops.

“Insects play an important role in enabling ecosystems to function, including pollination, decomposition and pest control,” Dr. Pedersen said.

“Our research provides important additional evidence of the threat posed as the Asian Hornets spread across Europe,” said Dr. Peter Kennedy of the University of Exeter.

The researchers identified 1,449 operational taxonomic units in the internal organs of hornet larvae.

More than half could be identified as a specific species, but the rest could not. Therefore, the exact number of species contained in the sample is not certain.

“We have provided the most comprehensive view of the European Asian Hornet diet to date, highlighting the highly broad and flexible potential prey,” the scientist said.

“The dietary composition shows that it differs across geographical regions and throughout the Hornets' active season, indicating high adaptability to new ecosystems. It drives both the invasive success of Asian hornets and the risks they pose to a wide range of native invertebrate fauna.”

“The growing prevalence of dietary bees in Europe has agreed to previous research and reports from beekeepers, supporting concerns about the risks of aquaculture.”

“Our results found that Asian hornets exhibit high predation frequencies on wild pollinators and recyclers, revealing further potential ecosystem-level pressures, implying a threat to the diversity of pollinators and recyclers and the resulting ecosystem services.”

The Flores hominin likely descended from ancient Asian Homo erectus

Two recently discovered small hominin species, Homo floresiensis and Homo luzonensisraises the question of why such extreme body size reduction occurred in extinct human species in island environments. Previous research at Mata Menge on the Indonesian island of Flores has shown that early Middle Pleistocene human ancestors Homo floresiensis The jaws and teeth were even smaller. Now, paleoanthropologists have discovered additional hominid fossils in the same deposits at Mata Menge. The adult humerus (the lower half of the upper arm bone) is estimated to be 9 to 16 percent shorter and thinner than the type specimen. Homo floresiensis It is estimated to be about 60,000 years old and is smaller than the humerus of an adult human from the Plio-Pleistocene epoch. Homo floresiensis The lineage probably evolved from early Asia. Homo erectus This was a lineage that had existed for a long time on Flores Island, with a remarkably small body size, for at least 700,000 years.

Homo floresiensis This is a small hominin species from the Late Pleistocene discovered in a limestone cave in Liang Bua, western Flores.

Archaeological evidence suggests that this species lived in Liang Bua as recently as 50,000 years ago, around the time that our species first appeared. Homo sapienshas been established in southern Australia for a long time.

The origins of the mysterious humans from Flores have been much debated.

The first hypothesis was Homo floresiensis They were dwarf descendants of early Asians Homo erectus.

Another theory is that “Hobbits” are remnants of an earlier human race that originated in Africa around 1000 BC. Homo erectus If you are naturally short, some good candidates are: Homo habilis or Australopithecus afarensisThis species includes the famous “Lucy”.

Besides Liang Bua, hominin fossils have only been found at one other site on Flores, at the open-air site of Mata Menge, 75 km east of the cave.

Located in the sparsely populated tropical grasslands of the Soa Basin, the site has previously contained several other hominin fossils, including a jaw fragment and six teeth, unearthed in sandstone deposits near a stream some 700,000 years ago.

The Mata Menge fossils are 650,000 years older than the Liang Bua man and have been found to belong to at least three individuals, with jaws and teeth slightly smaller than those of the Liang Bua man. Homo floresiensisThis suggests that small body sizes evolved early in human history on Flores.

However, because no bones below the skull have been found in the fossil record from this site, it is not possible to confirm whether these Soar Basin hominins were at least as large, or even slightly smaller. Homo floresiensis.

Furthermore, due to a lack of diagnostic specimens, it was unclear to which species the Mata Menge fossils belonged.

However, some of the teeth are thought to be intermediate in morphology to earlier Asian teeth. Homo erectus and Homo floresiensis.

in New paper Published in the journal Nature CommunicationsProfessor Yosuke Kaifu of the University of Tokyo and his colleagues report the discovery of three additional hominin fossils at the 700,000-year-old Mata Menge site after several on-site excavations at the site.

Most importantly, this new assemblage contains the first postcranial element, the distal shaft of the adult humerus.

The fossil limb bones discovered at the Mata Menge excavation site have been long awaited as they provide a wealth of evidence regarding the origins of our human ancestors. Homo floresiensis.

Digital microscopic examination of the microstructure revealed that the small humerus belonged to an adult individual.

Based on the estimated length of the bones, the team was able to calculate that the hominin was about 100 centimetres tall.

This is about 6cm shorter than the estimated height 60,000 years ago. Homo floresiensis Liang Bua skeleton (approximately 106cm based on femur length).

“This 700,000-year-old adult humerus is Homo floresiensis“This is the smallest humerus bone in the human fossil record anywhere in the world,” Professor Adam Blum, from Griffith University, said.

“This extremely rare specimen Homo floresiensis The body size was very small.”

“But the small size of these limb bones reveals that the hobbit's early ancestors were even smaller than we previously thought.”

Two additional hominid teeth from Mata Menge are also smaller in size, one of which is an early Homo erectus Java.

This similarity is Homo floresiensis It evolved from an older, more primitive type of hominin and has never been found anywhere else, not even in Indonesia, or anywhere else in Africa.

The Mata Menge skeleton now contains a total of 10 fossil specimens, representing at least four individuals, including two children.

They are all anatomically very similar to the Liang Bu. Homo floresiensis They are now considered to be an ancient variant of this human species.

However, this early form, although directly ancestral to the “hobbits”, had a less specialized dentition (more primitive teeth) than the descendants of Liang Bua.

Furthermore, the small arm bones indicate that extreme body size reduction occurred early in the history of Flores's population.

“The evolutionary history of humans on Flores is still largely unknown,” Professor Blum said.

“But the new fossils suggest that the story of The Hobbit Homo erectus “Maybe a million years ago, it somehow became isolated on this remote Indonesian island, and over time its body size dramatically decreased.”

First sighting of Asian elephant burying carcass captured

Elephant pulling a dead calf in a tea plantation in northern Bengal, India

Parveen Kaswan and Akashdeep Roy

Asian elephants intentionally burying the bodies of their calves has been documented in the first scientific report of such behavior in this species.

Five calves were found buried in a drainage ditch on a tea plantation in the northern state of Bengal, India, with their feet and legs sticking out of the ground.

Footprints and scat of various sizes indicate that members of the herd of all ages contributed to each burial. A night watchman at the complex reported hearing loud elephant cries, sometimes lasting 30 to 40 minutes, before the herd left the area.

Akashdeep Roy Researchers at the Indian Institute of Science Education and Research in Pune and Parveen Kaswan from the Indian Forest Service suggest that the sound of these bugles may represent mourning, and that during burials the herds are “helping and caring”. It suggests that the person exhibited a certain behavior.

“The burial of a calf is an extremely rare event in nature,” says Roy.

They were surprised to find the calf buried foot-deep, but if the herd had buried each calf together, this would be the most accessible position to place the carcass in the drain. , says Roy. For elephants, who are social animals, burying their calves' heads may be the most important thing they do, he says.

The calf's body was later exhumed and examined. Their ages ranged from three months to one year old, and many were malnourished and suffering from infections. Bruises along each calf's back suggest that they were dragged or carried long distances to the burial site.

African bush elephant (african loxodonta) have been observed covering carcasses with plants and returning to the location later. However, the Asian elephant (maximum elephas) In this study, we typically avoided returning to the burial site and used an alternative route instead.

“These observations provide impressive evidence of the social complexity of elephants,” he says. Chase LaDue At the Oklahoma City Zoo and Botanical Garden. “Some people have suggested that elephants seem to behave in a unique way towards their deceased relatives. [but] This paper is the first to describe what appears to be a methodical and planned burial of an elephant calf after it was taken to a burial site. ”

Still, Professor Radu said: “We must be careful how we interpret these results, especially since the mental and emotional lives of elephants remain largely a mystery to us.” There is.

He is not convinced that the position of the calf was intentional. “I could imagine an elephant pushing a dead calf into a narrow ditch, and given its awkward shape and weight distribution, the calf would land on its back with its legs in the air,” he says. “And because the depth of the trench is shallow, the feet are not buried, but this is not due to intentional burying of the head, but due to the unique topography of the burial site.”

The land where elephants once roamed freely is shrinking as humans expand, especially in India, the world's most populous country. Only about 22 percent of the land used by elephants is within protected areas.

“Understanding how elephants behave and respond to rapid changes in human-dominated landscapes may help develop conservation strategies that promote human-elephant coexistence.” Mr. Radu says.

Potential Spread of Dengue Fever-Carrying Asian Tiger Mosquitoes to the UK Within Decades | Latest UK Updates

The Asian tiger mosquito, which carries dengue fever, could be endemic in Britain by mid-century, government health experts say.

In recent years, insects have spread to most of Europe due to the warmer climate, tending to live in urban areas and feed during the day, putting people at greater risk.

They have striped bodies and are known for their ability to spread dengue fever, Zika virus, and chikungunya fever (diseases usually associated with tropical regions).

The UK Health and Safety Agency (UKHSA) fears dengue fever could be transmitted in London by 2060, and mosquitoes themselves could be widespread across the UK by the 2040s.

UKHSA entomologist Jolyon Medlock said surveillance at borders could help slow the spread of mosquitoes, and people should cover standing water and empty containers as the insects lay their eggs to keep mosquitoes away.

Professor Dame Jenny Harries, chief executive of the UKHSA, said: “What was called a tropical disease when I was trained many years ago will actually become a national household disease.”

Officials also said other food- and water-borne infections could become more common, increasing the risk of further pandemics.

The dangers of heatwaves will worsen, flooding will become more severe, and people’s mental health may be adversely affected.

Food prices could also become more volatile, as much of the food the UK imports comes from areas prone to climate impacts such as drought.

Wildfires that produce toxic smoke are also expected to occur more frequently during hotter, drier summers.

Young children, the elderly, and people with pre-existing conditions are most vulnerable to these threats.

“In the summer of 2022, temperatures in the UK exceeded 40 degrees for the first time on record,” Dame Jenny said.

“Nearly 3,000 excess deaths were recorded during this prolonged heat wave, while many other countries have experienced extreme heat and prolonged heat waves in recent months.

“Using a high emissions scenario, health-related deaths in the UK are estimated to increase by more than 100% in the 2030s, more than 500% in the 2050s and more than 1,000% by 2070.”

What is dengue fever and how is it spread?
Doctors fear an outbreak could occur in the UK too – and here’s why

The Earth is already 1.2 degrees warmer than pre-industrial levels, and given the amount of carbon in the atmosphere, further warming is already locked in, even if emissions start to fall overnight.

This means some adaptation will be needed, alongside emissions reductions, housing improvements, flood protection and extreme heat warnings, UKHSA said.

Mrs Jenny added: ‘Climate change is an important threat to public health around the world, not only through increased mortality from extreme temperatures and weather impacts, but also through increased spread of infectious diseases and worsened earth system vulnerabilities.”
