Aggressive ant species spreading north in Germany
An aggressive ant species is spreading ever further north in Germany and threatening to take down power and internet connections.
Ants of the invasive species Tapinoma magnum, which originates in the Mediterranean region, are spreading as far north as Cologne and Hanover, said ant expert Manfred Verhaagh from the Museum of Natural History in Karlsruhe.
"Super colonies have from hundreds of thousands to millions of individuals," he warned - far bigger than colonies of other ant species.
The invasion of the ant species and their colony-building is threatening buildings and technical infrastructure in Baden-Württemberg and other regions of Germany, scientists said.
In the town of Kehl, for example, there have already been power and internet outages caused by the ants.
The ant has also been noticed in other parts of Europe, such as France and Switzerland.
German scientists and authorities are now working together for the first time in a project to stem the advance of the insects.
Tapinoma magnum has not yet been officially categorized as invasive, as it does not currently pose a large enough risk to local ecosystems.
Baden-Württemberg's state secretary for the environment, Andre Baumann, nevertheless said that he considers Tapinoma magnum to be a "pest," even if it is not legally labelled as such.

Bed Bugs May Have Been The First Urban Pest to Ever Plague Humans
Humans were letting the bed bugs bite long before beds existed, and while they do live on other species, we're the main reason this notorious parasite is still going strong. In fact, bed bugs might have been the first pest to plague our cities – earlier than the black rat, for instance, which joined us in urban life about 15,000 years ago, and even the German cockroach, which only got the memo about 2,100 years ago. Researchers think the blood-sucking pests – Cimex lectularius – first jumped from their bat hosts onto a passing human some 50,000 years ago, a move which would change the course of the insect species forever. Human bed bugs, it turns out, have boomed since the Last Glacial Maximum about 20,000 years ago. But it's a different story for those populations that continued living on bats. "Initially with both populations, we saw a general decline that is consistent with the Last Glacial Maximum; the bat-associated lineage never bounced back, and it is still decreasing in size," says entomologist Lindsay Miles, from Virginia Tech. "The really exciting part is that the human-associated lineage did recover and their effective population increased." The researchers were able to track this evolution because the human bed bugs have a much narrower genetic diversity, since only a few 'founders' probably came with us when we abandoned life in caves. But our move into cities around 12,000 years ago is what really kicked off the human bed bug boom. This was only briefly interrupted when DDT was invented in the 1940s. Populations crashed, humans slept sweetly, and then five years later, the bed bugs were back. Since then, bed bugs have travelled around the world with us, and even become resistant to our pesticides. For now, it seems, bed bugs are here to stay. It's been a long-term relationship, after all. The research is published in Biology Letters.

Seals playing computer games for science reveal how they navigate in murky water
One by one, Nick, Luca and Miro took their places in front of a screen at a German research lab to participate in a video game for science. The task was straightforward. While viewing a simulation of moving through the ocean, the subjects would touch a red target on the left if they thought they were moving left, and a red target on the right if they thought they were moving right — an action these creatures learned by being rewarded with fish. Using a series of dots streaming across a black screen that mimicked particles in murky water, researchers observed whether harbor seals used optic flow, or the movement of objects across one's field of vision, to determine the direction in which they are moving, according to a May 29 study published in the Journal of Experimental Biology. Harbor seals are especially adept at navigating open water, which can be 'a strangely claustrophobic experience' for humans as our view drops to just a few centimeters, according to an article published in the Journal of Experimental Biology about the study. Seals are known to use their highly sensitive and dexterous whiskers to navigate and hunt, but the role of visual perception is less studied. The team designed three computer simulations. The first simulated a seal moving through the open sea with dots coming at them; the second simulated the sea floor passing beneath the seal; and the last simulated the sea surface above the seal's head, according to the article. Three humans participated in the simulation for skill comparison, according to the study. The seals' heading accuracy was 'comparable, but slightly inferior to the heading accuracy of humans and Rhesus macaques (a species of monkey),' according to the study. 'The (seals) were perfectly capable of determining which direction they were traveling in based simply on the dots streaming in their view; exactly as the cloudy water, seabed or water surface would appear to move when they are swimming,' the article said. ___ © 2025 The Charlotte Observer.

Small Ear-Wax Sample, Big Diagnostic Clues
A recent BBC report suggests that cerumen, commonly known as earwax, may harbor biomarkers to aid in the diagnosis and monitoring of conditions such as cancer, Alzheimer's disease, and metabolic disorders. Cerumen Profile The primary function of cerumen is to keep the external auditory canal clean and lubricated, preventing invasion by bacteria, fungi, and insects. Beyond this, cerumen may reflect systemic metabolism by concentrating a broader array of compounds than blood, urine, sweat, and tears. Its relative stability allows the accumulated cerumen to provide long-term snapshots of metabolic changes. Disease Associations Researchers have defined genetically determined wet and dry cerumen phenotypes. In the US, Caucasian, African American, and German women with wet cerumen faced roughly four times the risk of dying from breast cancer compared with Japanese and Taiwanese women with dry cerumen. The study found that Japanese women with breast cancer were more likely to carry the wet-cerumen allele than were healthy controls. However, large-scale studies in Germany, Australia, and Italy failed to confirm these associations. A recent analysis reported that patients with Ménière's disease had lower levels of three fatty acids in the cerumen compared with healthy controls — the first biomarker identified for that disorder. In a 2019 study led by Nelson Roberto Antoniosi Filho, PhD (Federal University of Goiás Goiânia in Brazil), researchers analyzed cerumen samples from 52 patients with lymphoma, carcinoma, or leukemia and 50 healthy volunteers, using a method that identifies volatile organic compounds (VOCs). The researchers identified 27 VOCs that served as diagnostic fingerprints for cancer, predicting the cancer status with 100% accuracy. The assay could not distinguish among cancer types, indicating that these VOCs represent a general response to malignant cells. Another investigation by the same group showed that cerumen analysis can detect metabolic disturbances in premalignant stages when cells exhibit dysplastic changes that may lead to cancer but remain nonmalignant, potentially enabling much earlier intervention. The team is also investigating whether metabolic alterations caused by neurodegenerative diseases, such as Parkinson's disease and Alzheimer's disease, can be detected in the cerumen. Diagnostic Tool Antoniosi Filho and colleagues proposed that cancer, as a mitochondrial metabolic disorder, releases VOCs that accumulate in cerumen, allowing differentiation between healthy and cancerous individuals via an assay they call the cerumenogram. The aim was to develop a cerumenogram as a diagnostic tool to accurately predict certain cancers from a small cerumen sample. Clinical Adoption Hospital Amaral Carvalho in Jaú, São Paulo — a national reference center for oncology and bone marrow transplantation — has recently implemented cerumenograms for cancer diagnosis and monitoring. Future Directions An April 2025 paper in Scientific Reports by Antoniosi Filho concluded that the cerumenogram could: 1. Identify oncologic risk by detecting premalignant cells before cancer onset, introducing a novel screening modality 2. Show that mitochondrial impairment in premalignant cells — such as hypermetabolic inflammation and dysplasia — produces the same VOC biomarkers as malignant cells, distinct from those in benign lesions, opening new paths for risk management and early intervention 3. Correlate cerumenogram findings with established imaging techniques such as 2-deoxy-2-[fluorine-18] fluoro-D-glucose PET/CT (18F-FDG PET/CT) and gallium-68 PSMA PET/CT, demonstrating alignment with clinical results while offering a noninvasive, lower-cost alternative 4. Monitor treatment response and cancer remission, supporting assessment of therapeutic efficacy and cellular return to normal 5. Confirm metabolic indicators of malignancy to guide clinical decisions alongside imaging and biopsy 6. Drive the development of targeted therapies aimed at metabolites overproduced in malignant conditions. In conclusion, the cerumenogram may serve as a valuable assay for evaluating precancerous indicators, cancer progression, and remission, with the potential to reduce mortality, alleviate patient suffering, and lower disease-related costs. Congratulations to Nelson Roberto Antoniosi Filho, PhD, and his team.
