An international team of vets has made a breakthrough in a vaccine trial for a virus that killed seven elephants at Chester Zoo. Elephant endotheliotropic herpesvirus (EEHV) is a leading cause of death for young Asian elephants, both captive and wild, with no cure. Trials with adult elephants at Chester Zoo found a new vaccine safely triggered a strong immune response. The team (University of Surrey, Chester Zoo, Animal and Plant Health Agency) observed no side effects. This follows five [...]

Trees across the Amazon rainforest are growing larger in response to rising levels of carbon dioxide in the atmosphere, according to a major new study. The research, published in the Nature Plants journal, found that the average size of trees in the Amazon has increased by 3.2 per cent every decade for at least the past 30 years. Scientists say the trend is consistent with the fertilising effect of higher concentrations of CO2, which can boost plant growth. The findings come from the [...]

Astronomers are investigating a little-known and largely unseen group of asteroids that quietly orbit the sun alongside Venus — and there may be many more of them than we thought. "It's like discovering a continent you didn't know existed," Valerio Carruba of the São Paulo State University in Brazil, who led the analysis, told Space.com. "It's very likely there are other asteroids we don't observe today." These space rocks, known as " [...]

A hidden swarm of "city killer" space rocks, known as co-orbital asteroids, is likely hiding around Venus and could pose an "invisible threat" to Earth over the coming millennia if the asteroids are not found, new simulations suggest. However, there is no immediate danger to our planet, researchers told Live Science. Co-orbital asteroids are space rocks that orbit the sun alongside a planet or other large body without truly orbiting the larger object. There are currently [...]

Scorpions are “taking over” Brazilian cities, researchers have warned in a paper that said rapid urbanisation and climate breakdown were driving an increase in the number of people being stung. More than 1.1m stings were reported between 2014 and 2023, according to data from the Brazilian notifiable diseases information system. There was a 155% increase in reports of stings from 2014 to 2023, according to research published in the journal Frontiers in Public Health. The rise [...]

"Our team has discovered a new fossil ant species representing the earliest undisputable geological record of ants," study co-author Anderson Lepeco, a researcher at the Zoological Museum of the University of São Paulo in Brazil, said in a statement. "What makes this discovery particularly interesting is that it belongs to the extinct 'hell ant,' known for their bizarre predatory adaptations." The newly discovered ancient ant species, which researchers have [...]

Research continues to emerge showing that alcohol is bad for our health, increasing the risk of at least seven different types of cancer, disrupting sleep and hurting mental-wellbeing. Now, scientists have uncovered the exact number of years drinking could cut from your lifespan—and how many drinks per week produce the worst health outcomes. In a new study published in the journal Neurology, researchers found that heavy drinkers—those who had eight or more drinks per [...]

Early humans may have started using language for communication over 100,000 years ago, a new review of genomic data shows. There are some 7,000 identified languages spoken globally, and researchers say they all have a common origin back when early human groups started spreading across the world. Our ancestors developed the cognitive ability for language, combining vocabulary and grammar into a system of expression, over millions of years of evolution. The capacity to talk in humans [...]

A new coronavirus discovered in bats in Brazil has been found to share similarities with the deadly Mers virus but its risk to humans remains unclear, scientists say. Researchers from São Paulo and Ceará discovered the novel coronavirus in collaboration with colleagues from Hong Kong University (HKU), and found it resembles the Middle East respiratory syndrome virus (Mers-CoV). The Mers virus was first identified in 2012 in Saudi Arabia and has since led to over 850 deaths [...]
