Today, a homegrown solution in Uganda could change how millions protect themselves from mosquitoes. Researchers have found that a lotion made from catnip oil is as effective as DEET in repelling mosquitoes, offering a cheaper alternative for malaria-prone regions. Later, we'll explore how forensic science is tackling wildlife poaching. But first, let's dive into the catnip lotion breakthrough. Catnip lotion matches DEET in mosquito repellent trials in Uganda. In a promising development, researchers from Cardiff University and their Ugandan partners have demonstrated that a lotion made from catnip oil can effectively repel mosquitoes. Field trials in Uganda showed that a six percent catnip oil lotion was just as effective as the commonly used DEET-based repellent. This discovery could provide a more affordable option for communities in malaria-endemic regions, where mosquito-borne diseases are a significant concern. The research, presented at the Society for Experimental Biology conference, highlights the potential of locally grown catnip plants to offer a sustainable and cost-effective solution. With the success of these trials, the catnip lotion could soon become a vital tool in the fight against malaria, benefiting millions who rely on mosquito repellents for protection. Tampons are becoming a valuable medical tool. In an innovative twist, tampons are being repurposed for medical use, offering a new way to collect biological samples for women's health screenings. Inspired by her own experience, Ridhi Tariyal has developed a method to use tampons for collecting menstrual effluence, which contains valuable biological material. This approach could revolutionize how women monitor their reproductive health, providing a non-invasive and accessible alternative to traditional blood tests. The EU-funded Vaginal Microbiome Screening project is exploring this potential, aiming to make gynecological care more comfortable and effective. By leveraging a common product, this initiative could significantly improve early detection and preventive care for conditions like ovarian cancer, offering women a more convenient way to manage their health. Reducing microplastic exposure: four habits to prioritize. As microplastics continue to be found in human tissues, researchers are urging people to adopt habits that reduce exposure. Microplastics, tiny plastic particles, have been detected in various human organs, raising concerns about potential health impacts. While the long-term effects are still being studied, early findings suggest links to inflammation and hormone disruption. To minimize exposure, experts recommend simple changes such as avoiding plastic packaging, using natural fibers, and filtering tap water. These steps can help reduce the intake of microplastics, which are prevalent in everyday environments. As awareness grows, these habits could play a crucial role in protecting human health from the pervasive presence of microplastics.
## Feature Story
Forensic science is making strides in the fight against wildlife poaching. Advances in forensic techniques are providing new tools to combat the illegal wildlife trade, a $23 billion industry that threatens biodiversity and fuels crime. At the forefront of this effort is the UK’s Wildlife Crime and Forensics Unit, which has developed methods to reveal human traces on poached animals. A striking example is the use of fluorescent powder to expose fingerprints on a green sea turtle, captured in a photo by award-winning journalist Britta Jaschinski. Her work, showcased at the Earth Photo 2026 Awards, highlights the power of visual storytelling in raising awareness about wildlife crime. Forensic science is not only about catching poachers but also about building strong legal cases. Techniques like DNA sequencing and fingerprint analysis are crucial in linking suspects to crimes, increasing the chances of prosecution in a field where convictions are rare. The Zoological Society of London’s Wildlife Forensic Lab is at the cutting edge, developing methods that could transform how wildlife crimes are investigated and prosecuted. As these forensic tools become more sophisticated, they offer hope for more effective enforcement against poaching. The implications are significant: by disrupting the illegal wildlife trade, these efforts can help preserve endangered species and protect ecosystems. Moving forward, the integration of forensic science into wildlife conservation strategies could be a game-changer, offering a new line of defense against the exploitation of our planet's most vulnerable creatures.
