Recent advancements in long-read sequencing technology and assembly algorithms have enabled the generation of high-quality diploid genome assemblies, which provide a more comprehensive view of complex variants and enhance our understanding of their formation mechanisms and functional consequences.

Kelly Chibale describes the drug discovery process as a fairy-tale quest, stating, 'It doesn't mean that there aren't surprises or miracles. They do happen, but you have to kiss many frogs before you meet the prince.' This metaphor illustrates the challenges and unpredictability in finding effective medicines.

Scientists have long known that vast colonies of bacteria, viruses and other microorganisms—a population collectively called the microbiome—live on and inside the human body. But how they influenced our health was long a mystery. In just the past few years, we've learned that myriad factors, from the food that we consume to the amount of time that we spend sleeping to our genes to our home, all affect our microbiome.

The strain the animals have contains a mutation allowing it to more easily transmit between mammals. It is also a different variation than the ones found in dairy cows and commercial poultry. This one is Eurasian in origin, first seen in 2022. It has been detected in birds that fly along the Pacific Flyway, and is responsible for a mass mortality event in 2023 in northern fur seals on an island in eastern Russia.

In children below the age of five, whose immune systems are still developing, the infections can lead to malnourishment; they cause up to 42,000 deaths annually. Soon there may be a vaccine to protect against these infections. In the Lancet Infectious Diseases last month, scientists shared the results of the first study to evaluate the safety and efficacy of an ETEC-controlling vaccine in a large pediatric population in Gambia.

Risks of outbreaks with pandemic potential rise with increasing land-use change, biodiversity loss and climate change. The Pandemic Agreement adopted by the World Health Assembly in 2025 marks a historic shift that establishes the One Health approach as a legally binding obligation for pandemic prevention.

I am open-minded; I believe in integrative practices, and I agree that the medical establishment can be arrogant and unduly influenced by the pharmaceutical industry, which now funds so much of medical research. But I fully understand Scherer's frustration with his interminable discussions with Kennedy about scientific articles.

Bats carry a lot of very deadly pathogens like Ebola virus, Nipah, Hendra, coronavirus, and also rabies virus. People are finding more and more bat-borne viruses. When such viruses are transmitted to humans, the results are often fatal so there's a lot of interest in trying to prevent spillover in the first place.

In a study published in Science Advances, researchers in China fed Aedes aegypti mosquitoes blood that contained either a vaccine against Nipah virus or the rabies virus. The viruses, contained in the vaccines, replicated inside the insects and reached their salivary glands, allowing them to pass on the vaccine when feeding on bats or when the bats ate the insects.

Irish mosquitoes are typically found in wetlands, floodplains, coastal saltmarshes Ireland has as many as 21 species of mosquito present nationwide, but scientists say it's rare for them to bite humans here.

We don't know what exactly investigators found or whether they are in any way harmful. However, we do have an intriguing clue. The property was linked to Jia Bei Zhu, a 62-year-old Chinese citizen who was arrested in October 2023 on charges of manufacturing and distributing misbranded medical devices and making false statements to the FDA, according to NBC News.

Highly pathogenic avian flu, or bird flu, has been confirmed in the Emerald Necklace. Risk of human infection is currently low. As always, please do not feed, touch, or remove birds from Boston parks.

For the first time, cameras in Africa captured a 'dynamic network' of wildlife interacting with thousands of infected bats believed to be carrying the Marburg virus, which is a rare but extremely dangerous disease that belongs to the same family as Ebola. The new videos revealed at least 14 different types of animals, including leopards, hyenas, monkeys, birds and rats, actively hunting herds of Egyptian fruit bats.

A statement by the government's region 5 livestock office for Chiang Mai, said the animals had been infected with canine distemper virus, with veterinarians also identifying mycoplasma bacteria as a secondary infection. Earlier however, Somchuan Ratanamungklanon, director general of the department of livestock development within the Thai agricultural ministry, told the Thai outlet Matichon that the tigers had been infected with feline panleukopenia.

Each day, they pore over reams of data about how the virus is evolving worldwide, how well last year's shot performed, and which strains might be easiest to mass produce for a vaccine. The meeting, convened by the World Health Organization twice a year, is a critical moment for the WHO's Global Influenza Surveillance and Response System.

This is exceptionally rapid detection of an outbreak in free-ranging marine mammals, said professor Christine Johnson, director of the Institute for Pandemic Insights at UC Davis' Weill School of Veterinary Medicine. We have most likely identified the very first cases here because of coordinated teams that have been on high alert with active surveillance for this disease for some time.

DNA variants near a gene called MSRB3 - which is important for hearing in humans - could determine whether a dog's ears are pendulous like a basset hound's or stubby like a rottweiler's. Researchers analysed the genomes of thousands of canines and found that small, single-letter changes to DNA in a region of the genome near MSRB3 could boost the gene's activity. The boost can increase the rate at which ear cells proliferate, resulting in longer ears.
