NewsImaging reveals bacterial symbionts in the ovaries of tiny, aquatic crustaceans
Researchers have imaged a heritable form of bacterial symbiosis inside the reproductive system of tiny crustaceans known as ostracods. Bacteria from the genus Cardinium live inside the egg cells and tissues of ostracod ovaries, transmitted from mothers to offspring.

NewsRainfall and temperature shape mosquito fauna in Atlantic Forest bromeliads, including malaria vectors
Results from a study of mosquito larvae conducted in a natural area in the municipality of São Paulo (Brazil) may help estimate the effects of climate change on disease transmission risk in the biome.

NewsCracking leishmaniasis: new DNA test to track infection
A new study offers an innovative way to track the spread of leishmaniasis, a parasitic disease affecting both animals and humans. Researchers developed a fast, reliable method to identify sand fly species, detect Leishmania parasites, and determine the source of their blood meals from a single sample.

NewsMissing links for rabies in Peru highlights global threats of health inequity
Researchers found that efforts to track dog-related rabies in poorer areas of Peru’s second largest city were lacking even though more dogs were found to have the disease there than in wealthier neighborhoods.

NewsEgypt becomes the seventh country in the Eastern Mediterranean Region to eliminate trachoma as a public health problem
The World Health Organization (WHO) today announced that Egypt has successfully eliminated trachoma as a public health problem, marking a historic public health milestone for the country and WHO’s Eastern Mediterranean Region (WHO EMR).

NewsFirst detection of zoonotic Rickettsia species in dog ticks from Malawi reveals potential public health risk
An international research team has reported the first molecular detection of Rickettsia bacteria in ticks collected from domestic dogs in Malawi, addressing a significant knowledge gap in understanding tick-borne disease risks in southeastern Africa.

NewsResearchers capture first high-res images of deadly yellow fever virus
Researchers have captured the first high-resolution images of the yellow fever virus (YFV), a potentially deadly viral disease transmitted by mosquitoes that affects the liver.

NewsNew study reveals not all bats carry equal viral risk
A groundbreaking study sheds new light on the relationship between bats and dangerous viruses, showing that contrary to widespread assumptions, not all bats carry viruses with high epidemic potential, only specific groups of species.

NewsAntimicrobial peptides can reduce salmonella in chickens
A new study has found that antimicrobial peptides can combat Salmonella infections in chickens, a major cause of foodborne disease in the U.S. This discovery could help improve food safety and protect public health without relying on antibiotic use.

NewsAI and citizen science reveal potential first detection of invasive malaria mosquito in Madagascar
Researchers used AI and citizen science to identify what may be the first Anopheles stephensi mosquito ever detected in Madagascar — a species capable of spreading deadly malaria across urban Africa. A single smartphone photo submitted through NASA’s GLOBE Observer app led to the discovery.

NewsViral infections at the heart of why honey bees overthrow their queen
Common viral infections shrink a queen bee’s ovaries, reducing both her egg-laying capacity and her production of methyl oleate, a pheromone that normally keeps worker bees loyal. When methyl oleate levels drop, workers will “smell” the queen’s weakness - and begin preparing her successor.

NewsWarmer Nordic springs double the incidence of avian malaria
A unique long-term study, in which biological samples were collected from the same population of blue tits over a 30-year period, shows that rising spring temperatures have doubled the incidence of avian malaria in southern Sweden.

NewsStudy uncovers origins of urban human-biting mosquito, shedding light on uptick in West Nile virus spillover from birds to humans
The research disproves the theory that the mosquito evolved in the London underground by dating the mosquito’s origin back over 1,000 years and identifies the genetic links between bird-biting and human-biting mosquitoes, key to West Nile transmission.

NewsAfter injuries, carpenter ants use amputation to stop potential infections from spreading
Carpenter ants are not squeamish when it comes to caring for the wounded. To minimise the risk of infection, the insects immediately amputate injured legs – thereby more than doubling their survival rate.

NewsBay Area Lyme Foundation opens applications for 2026 Emerging Leader Awards and research grants
Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the US, has announced its call for applicants from academia and the private sector for the 2026 Emerging Leader Awards (ELA).

NewsRare virus transmitted by rats infects woman in Germany—link to private pet rat breeding facility
The Seoul virus, which has been rarely detected in Germany to date and can be transmitted by rats, caused a woman to become seriously ill. Given that rats are becoming increasingly popular as pets, health experts view this as a warning sign.

NewsNew hope for cats with eye infections: Study finds common cold sore cream safe and effective for feline use
A common human cold sore cream may soon help cats with painful eye infections: researchers found that 1% penciclovir cream (Fenlips®), when applied to cats’ eyes, was safe, well-tolerated, and maintained antiviral levels for over eight hours.

NewsNew insights into malaria could reshape treatment
A sodium pump essential to the malaria parasite’s survival, PfATP4, has emerged as one of the most attractive drug targets. A new study presents the first high-resolution 3D structure of PfATP4 and identifies a previously unknown but essential binding partner.

NewsMosquito saliva may hold clues to fighting chikungunya inflammation
Scientists have uncovered a surprising mechanism showing how mosquito saliva can alter the human body’s immune response during chikungunya virus (CHIKV) infection - it not only transmits the virus but also influences how the body’s immune system responds.

NewsIn the midst of a global dengue epidemic, Wolbachia kept a Brazilian city safe
In the middle of the world’s worst global dengue epidemic, a city in Brazil was effectively protected by an innovative program that introduced the bacterium Wolbachia into the local mosquito population, lowering the rate of dengue by almost 90 per cent.
