Researchers have created a new surface coating for polyetheretherketone, a material commonly used in orthopedic implants. The coating combines silver nanoparticles, which fight bacteria, with a calcium phosphate layer that encourages bone growth. This dual approach makes the implant surface both antibacterial and supportive of healing. Laboratory tests showed the coating reduced harmful bacteria by more than 90% while improving bone cell attachment and mineralization. The results suggest this strategy could lower infection risks and promote faster bone repair, offering safer and more effective implants for patients needing orthopaedic surgery.

Graphene-based self-powered sensors are emerging as a powerful solution for real-time health-monitoring and autonomous sensing systems. Owing to graphene’s exceptional electrical conductivity, flexibility and biocompatibility, these sensors can function without external power, drawing energy from mechanical, thermal or biochemical sources. Practical implementations in wearable electronics, implantable devices and smart environmental systems demonstrate the real-world impact of these innovations. The role of graphene-based materials extends beyond healthcare into robotics and soft electronics, where its properties support the development of self-powered, skin-like interfaces. As research continues to address scalability, long-term stability and miniaturization, graphene-based biosensors are expected to become central components in next-generation bioelectronic platforms.

People sit among the most monogamous mammals alongside meerkats and beavers, according to a new study. Researchers analysed genetic data to compare the number of full and half siblings seen across more than 100 human societies with data from 34 mammal species. Despite considerable cross-cultural variation, the proportion of full (rather than half) siblings seen in humans (~65% on average) is similar to that seen in monogamous mammal species, and is consistently higher than in non-monogamous mammal species (~9% on average), including chimpanzees. These results are consistent with the characterisation of monogamy as the being the predominant human mating system.

Preclinical cancer research commonly relies on genetically identical lab animals, limiting its relevance to human patients and contributing to costly drug failures. A new study introduces an innovative mathematical framework that creates validated 'virtual clones' of lab mice from limited experimental data. Using lung cancer as an example, researchers successfully linked tumour growth to survival at an individual level, accurately predicting treatment outcomes. By capturing real-world biological variability, these virtual clones could significantly reduce reliance on animal testing, offering a faster, cheaper, and more predictive approach for screening new cancer therapies and identifying which patients are most likely to benefit.

Crop pests and diseases remain a significant obstacle to sustainable agriculture, necessitating innovative and eco-friendly detection solutions. A new study introduces PestReKNet-X, an advanced AI tool that helps farmers protect their harvests while reducing chemical use. Trained on over 100,000 images of 22 pest and disease types, it correctly identifies them in 95 out of 100 cases. Unlike many other systems, it also shows farmers why it made a decision, using easy-to-understand visual highlights. By giving clear explanations and measuring how confident it is in each result, PestReKNet-X offers a reliable and transparent way to support sustainable farming around the world.

04/01/2026

Reflection of circularly polarized light by Chrysina beetles has been one of the ever-present themes in the study of structural colours in Nature. The study of the metallic-looking exocuticles of silvery, golden, red and green Chrysina species has produced detailed models of their specular reflective properties. Matt-green Green Chrysina beetles show left-handed circularly polarized light reflections produced by a helicoidal chitin-protein fibre structure, but, unlike reflections of the well-studied golden and silver species, their reflections look diffuse as a result of having an exocuticle with small craters that spread local specular reflections in many directions. At the micrometre scale, the curved reflective structure at the craters behaves as concave reflectors projecting real images above their surfaces, while the convex rims separating the craters form instead virtual images below. The result is an optical illusion where the real topography is inverted: the craters look like hills and the rims like valleys. Researchers have successfully modelled the resulting pattern of multi-coloured reflections, imagining the curved, helicoidal structure as a stack of wavelength-selective micro-reflectors. This spatially projected imaging interpretation becomes relevant for optical characterization studies of such structures at the microscale.

Fossilised melanosomes reveal colour patterning of a sauropod (long-necked) dinosaur. A new study investigates the fossilised scales of the dinosaur Diplodocus and marks the first instance of colour patterning found in a sauropod dinosaur. The scales are preserved 3-dimensionally as clay minerals with groupings of melanosomes (microscopic melanin bearing structures that are responsible for colour patterning). Disc-shaped objects, hypothesized to be a type of melanosome, are also found in the scales. Their bizarre shape makes it impossible to determine the true colour of the scales, though the results show juvenile sauropods could create more diverse melanosome shapes than previously thought, similar to modern birds and mammals.

A rare fossil from the world-famous Mazon Creek in Illinois reveals the first known case of algal infection in extinct horseshoe crabs. An exceptionally rare, 300-million-year-old specimen of Euproops danae shows unusual dimples across the exoskeleton. These abnormal structures are considered due to algae or parasites that infected the animal during life. Comparisons with modern horseshoe crabs suggest the infection occurred in a fully grown individual, marking a terminal stage of growth in the fossil animal. This discovery sheds new light on how ancient parasites interacted with their hosts, underscoring the scientific value of exceptional preservation sites.

Animals often fight over valuable resources like food, space, or mates, and their decisions to engage depend on how likely they are to win. Males of the fruit fly (Drosophila prolongata) engage in territorial contests, using their elongated forelegs as weapons to fend off rivals and secure access to females and food. Researchers used this highly aggressive fruit fly to examine how differences in body size and leg (weapon) size affect contest behaviour. They found that even when flies are genetically identical and raised in the same conditions, individuals still differ in their contest behaviour and adjust their aggression depending on their rival’s size. This shows that small environmental differences influencing body and weapon size can strongly shape how individuals behave and compete.

Killer whales and humans share a trait that is otherwise rare in nature: a long female menopause. Whilst decades of field studies have revealed the important positive impact of a living menopausal grandmother in both humans and killer whales, the genes responsible for this trait remain elusive to science. In this 'thought experiment' researchers outline why the X-chromosome may play an important role in the evolution of menopause. They deduce this from the patterns of inheritance of the X-chromosome which result in granddaughters inheriting more of the paternal grandmother's X-chromosome, than other grand offspring. This could explain why grandmothers invest preferentially in their sons: to increase their genetic legacy.

Why do sea turtles not nest every year? Many vertebrates breed every year, but some species only reproduce every two or more years (non-annual breeding). In sea turtles, non-annual breeding has been linked to their long migrations. However, a conundrum is that sea turtle populations with short migrations still tend to be non-annual breeders. Researchers solve this conundrum by showing that non-annual breeding in sea turtles is linked to high time and energy costs associated with mating and nesting, regardless of migration distance, and is favoured due to their generally high adult survival rates.
