Dengue, chikungunya risk becoming endemic in Europe as mosquitoes head north
Nearly half the global population is now at risk of contracting dengue and chikungunya, which were once limited to the tropics, due to the warming planet. Both viruses, transmitted by mosquitoes, can occasionally be fatal. The symptoms include a high fever, headache, body aches, nausea and rash.
The tiger mosquito, in particular, is venturing farther north as global temperatures rise due to man-made climate change.

Seek Labs Maps High-Burden Mosquito-Borne Infectious Diseases with BioSeeker™, Accelerating Therapeutic Discovery for Chikungunya, West Nile Virus, and Zika
SALT LAKE CITY--(BUSINESS WIRE)--Seek Labs, a biotech company boldly seeking a healthier world through AI-powered discovery, programmable therapeutics, and point-of-care diagnostics, today announced the successful mapping of three of the world's most persistent mosquito-borne infectious diseases—Chikungunya, West Nile Virus, and Zika—using its proprietary BioSeeker™ discovery engine. These newly mapped targets represent a critical expansion of the company's Global Disease Atlas and a major step forward in enabling the development of programmable therapeutics with Seek Labs' PTAP™ platform to combat vector-borne disease threats worldwide. By unlocking targets for Chikungunya, West Nile Virus, and Zika, BioSeeker has compressed years of discovery into weeks, paving the way for programmable, pathogen-specific therapeutics that could be deployed when and where they're needed most. BioSeeker Powers Precision Genomics for Programmable Therapeutics BioSeeker™ is Seek Labs' molecular strategist. By scanning thousands of viral and pathogenic genomes, it identifies conserved, high-potential sequences essential to disease survival and replication. These 'genomic weak points' serve as blueprints for Seek Labs' Programmable Target Ablation Platform (PTAP™), which utilizes CRISPR systems to irreversibly disable pathogens with genomic precision. By unlocking targets for Chikungunya, West Nile Virus, and Zika, BioSeeker has compressed years of discovery into weeks, paving the way for programmable, pathogen-specific therapeutics that could be deployed when and where they're needed most. 'Mosquito-borne diseases are among the most complex and under-addressed in global health, spanning diverse pathogens, vectors, and regions with limited therapeutic tools,' said Jared Bauer, CEO of Seek Labs. 'BioSeeker gives us a global vantage point and a tactical advantage: we know where to strike, and we have the tools to do it.' Global Burden and Urgency Mosquito-borne viral diseases infect over 400 million people each year and remain some of the most overlooked threats in global and regional public health: Chikungunya, spread by Aedes mosquitoes, causes chronic joint pain and has resurged in explosive outbreaks across Asia and the Americas. Zika, also Aedes -borne, is linked to birth defects and neurological disorders, particularly devastating in pregnant individuals. West Nile Virus is spread primarily by Culex mosquitoes and, while many cases are asymptomatic, severe neuroinvasive disease can result in encephalitis, paralysis, and death, especially among older adults and immunocompromised individuals. Despite their scale, these diseases have no approved therapeutics in routine use. As vector ranges expand due to shifting climate conditions and urbanization, the window to respond grows narrower and the need for scalable, regionally adaptable solutions is greater. Additionally, recent reports of West Nile Virus in Utah have brought this growing threat even closer to Seek Labs' doorstep, underscoring the importance of local preparedness alongside global response. A Global Call to Partner in Programmable Therapeutics for Chikungunya, West Nile Virus, and Zika With pathogen mapping complete and PTAP guide designs ready for validation, Seek Labs is actively seeking development partners to advance these targets into the next generation of programmable infectious disease therapeutics. The company invites mission-aligned collaborators—including biopharma developers, government agencies, and global health organizations—to accelerate this next phase and help redefine what's possible in mosquito-borne disease control. About Seek Labs At Seek Labs, we don't wait for change—we build it. We're pursuing the breakthroughs the world can't wait for by developing programmable 'seek-and-destroy' therapeutics and point-of-care molecular diagnostics that close the gap between outbreak and intervention.

China's Mosquito Crackdown Tests a City's Post-Covid Patience
In the southern Chinese city of Foshan, officials are engaged in an all-out battle against chikungunya, a painful, mosquito-borne viral disease that could spread across the country. Soldiers wearing masks are fogging parks and streets with insecticide. Drones have been deployed to identify mosquito breeding sites. Researchers have introduced giant 'elephant mosquitoes,' whose larvae prey on the virus-carrying mosquitoes, and thousands of mosquito-eating fish have been released into city ponds. A virus transmitted by the bites of infected mosquitoes, chikungunya is rarely fatal, but it does cause fever and severe joint pain. It has infected around 8,000 people in China in four weeks, mostly in Foshan, and is the country's largest outbreak of its kind since the virus first emerged in the country in 2008. Experts say rising global temperatures have led to warmer and wetter weather there, allowing mosquitoes to thrive. To fight the outbreak, the authorities are also drawing on a familiar playbook honed during the Covid pandemic — mobilizing the city of 10 million in a 'patriotic public health campaign.' For some, that is evoking unhappy memories. At building entrances in the city, workers spray residents with mosquito repellent before allowing them in. Community workers in red vests go door to door, inspecting homes and ordering residents to dump any stagnant water. Those who don't cooperate could be fined or, in serious cases, face criminal charges for 'obstructing the prevention of infectious diseases,' according to an illustrated government explainer. At least five households have had their electricity cut for not cooperating, according to a notice issued by a neighborhood committee in the district of Guicheng. Want all of The Times? Subscribe.

Third worrying blow for Australia's most attractive ocean destinations
As 2025 began, alarm was raised about a record marine heatwave impacting half of Western Australia's coastline, then in March, a horror algal bloom began killing marine life across South Australia. In a third devastating announcement, on Wednesday, the Australian Institute of Marine Science (AIMS) confirmed sharp declines in coral cover across the Great Barrier Reef (GBR). All are directly linked to climate change. But scientists are reminding Aussies that despair isn't the answer, and the fight to save these precious destinations is not lost. Mass bleaching of coral is caused by warming water. Events on the GBR were unheard of until AIMS recorded its first bleaching in 1998, and since then, they've become the new normal, with events occurring in 2002, 2016, 2017, 2020, 2022, 2024 and 2025. Simple way the Great Barrier Reef can be saved AIMS research team leader for reef monitoring, Dr Mike Emslie, told Yahoo News Australia the latest annual summary report of the GBR's condition highlights the 'seriousness' of coral bleaching. But he wants to remind Australians that there is still substantial coral cover in parts, and 'it's worth fighting for'. 'It is by no means dead, but it is certainly under stress from continuous cumulative impacts,' he said. 'There are a lot of really beautiful, thriving coral communities still out there, and if we do give it a chance by taking meaningful action on greenhouse gas emissions and getting the warming trend under control, it will continue to flourish into the future.' What does the AIMS report reveal about the reef? AIMS began reporting on coral cover 39 years ago. The 2025 edition highlights that there is increased 'volatility' of reef-building hard coral cover, which is what AIMS measures. This means there will be rapid growth one year, and then a mass die-back the next. Researchers surveyed 124 reefs during the survey and found two reefs had less than 10 per cent coral cover, 77 had between 10 and 20 per cent, 33 had between 30 and 50 per cent, and two had more than 75 per cent. The declines are primarily driven by heat stress, and the 2024 mass bleaching was part of a global event that began a year earlier in the northern hemisphere, but cyclones and crown-of-thorns starfish also had a negative impact. Coral cover dropped over a year in all three regions: By a quarter in the northern region (Cape York to Cooktown). By 13.9 per cent in the central region (Cooktown to Proserpine) By almost one third in the southern region (Proserpine to Gladstone) Australia urged to set strong 2035 climate target to save reef Australia's federal government has committed to net-zero emissions by 2025, but it is on track to soon announce a target for 2035. ✈️ Australia greenlights plan to build airport road through rare animal's home 🐕 ACT government admits to unlawfully trapping dingoes for years 🐸 Alarm raised after strange backyard phenomenon worsens in Aussie region World Wide Fund for Nature Australia said the AIMS report highlights that the announcement needs to be 'strong'. 'In one fell swoop, climate change wiped out the encouraging coral recovery of recent years,' its head of oceans Richard Leck said. 'The Australian government can show it's determined to give the [GBR] a fighting chance by announcing a strong 2035 target backed by policies to deliver big emissions reductions.'
