Since the first case of epizootic haemorrhagic disease (EHD) in Spain was detected in cattle in November 2022, it has spread among farms in several autonomous communities in dozens of outbreaks. The mosquito-borne disease does not affect humans, but has the potential to cause economic losses.

One of the world's most invasive species is Solenopsis invicta, an ant native to South America with a painful sting. In an article published in Current Biology, experts confirm the first official sighting of this species in Europe: 88 nests spread over five hectares near Syracuse in Sicily, Italy. The ants could soon spread across the continent, causing serious environmental, health and economic problems. The study is led by the Institute of Evolutionary Biology (IBE) of the CSIC and the UPF.

According to a new report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), human activities have introduced over 37,000 exotic species to regions around the world. The document highlights that more than 3,500 of these are harmful invasive exotic species that are often overlooked until it's too late.

A study in mice found "mild metabolic and neuropsychological malprogramming" in the offspring of females who, during gestation and lactation, had ingested emulsifiers, substances used to improve the texture of ultra-processed foods. The article, led by a team from IDIBAPS in Barcelona and published in PLoS Biology, states that the consumption during these periods of carboxymethylcellulose and polysorbate 80 - two common emulsifiers - diluted in water was associated with metabolic and cognitive deficits in the mouse offspring.

The decline of insects in Central and Western Europe in recent years is mainly due to human activities and the intensification of agriculture, according to a study funded by three companies (Bayer, BASF and Syngenta) that manufacture pesticides. The paper, published in PLoS ONE, summarises an analysis of 82 other published studies and explains the causes of population declines in two groups of insects: carabids (ground beetles) and lepidopterans (including moths and butterflies). The authors estimate that "anthropogenic activities in general" are most responsible for this decline, followed by agricultural intensification (including pesticides) and climate change in third place.

Today it is difficult to see science policies that do not mention citizen science or citizen participation in science. On World Mosquito Day, which is celebrated on August 20, we analyze what has been achieved by the Mosquito Alert project, based on citizen science and which the Ministry of Health has supported this summer within the framework of the National Plan for Disease Prevention, Surveillance and Control Transmitted by Vectors.

The fires in Hawaii, which have left at least a hundred dead and hundreds missing, have devastated entire towns and villages and have put the issue of how to prevent such intense fires back on the table. World Wildfire Prevention Day is celebrated this Friday 18 August. The increase in the occurrence and recurrence of large wildfires jeopardizes the resilience of socio-ecological systems. Efforts in prevention must be a priority and constant throughout the year. We have a joint responsibility as a society to face this unprecedented problem, which will worsen in the coming years.

Influenza A can cause influenza in humans, birds, pigs, and other mammals. In 2009 and 2010, a pandemic caused by the pdm09 strain—popularly called 'swine flu' because it contained genetic sequences from avian, swine, and human influenza—caused thousands of human deaths worldwide. Since then, this lineage has crossed over 370 times from humans to pigs in the United States, according to a study published in PLOS Pathogens. The research also indicates that the circulation of the virus among pigs may cause further evolutionary changes in this lineage, which would increase the risk of the virus passing back to humans.

A team of South Korean researchers claims to have achieved a superconductor at room temperature and pressure for the first time in history. If true, it would mean a revolution in physics with implications for the whole of society. The material, called LK-99, is based on a copper-doped lead apatite framework. The article is a preprint and can be read in the ArXiv repository, where the research community shares their work before it is reviewed for publication in a scientific journal.

According to a statement issued Monday by the World Health Organisation (WHO), Poland has reported that "unusual" cat deaths have been found in several areas of the country. Of the 47 samples tested (46 from cats and one from a caracal, another type of feline), 29 were positive for the avian influenza A(H5N1) virus. The surveillance period for all contacts has now ended and no contacts have shown symptoms. According to WHO, "sporadic A(H5N1) infections of cats have been reported previously, but this is the first report of a large number of infected cats in a large geographical area within a country".
