By modeling how sound moved through the skull of Thrinaxodon, a 250-million-year-old mammal predecessor, researchers found it likely used an early eardrum to hear airborne sounds. This challenges the long-held idea that these animals mainly “listened” through their jaws or bones. The results reveal that a key feature of modern mammal hearing was already taking shape deep in prehistory.

Despite the physical challenge, their energy stores stay stable, suggesting the real danger lies in the delay itself.

NC State researchers found that larger infestations meant higher toxin levels, especially from female roaches. When extermination eliminated the pests, both allergens and endotoxins plummeted. The findings highlight how pest control is vital for cleaner, healthier air indoors.

While this messy shortcut helps tissues regenerate faster, it also leaves behind debris that can fuel inflammation and even cancer.

In the south, bites cause rock-solid blood clots, while in the north, they trigger flimsy clots that collapse almost instantly. This hidden divide means current antivenoms, made from pooled venom of uncertain origin, may not work equally well across the country.

A study from the University of Vienna shows they use a molecular mechanism known as BMP shuttling, once thought unique to bilaterally symmetrical animals like humans, insects, and worms. This surprising discovery implies that the blueprint for forming a back-to-belly body axis could date back over 600 million years, to a common ancestor of cnidarians and bilaterians.

But for all the medical breakthroughs of the 20th century, the best way to detect molecules has remained through liquids, such as blood. New research, however, could someday put a pause on pinpricks.

Although transplantation to different species is expected to bring benefits, it is still too difficult to produce offspring.

It was previously thought that combining chloroplasts (chlorophyll containing structures in the cells of plants and algae) with animal cells was not possible, and that the chloroplasts would not survive or function. However, results showed that photosynthetic action continued for at least two days. This technique could be useful for artificial tissue engineering. Tissues can struggle to grow due to a lack of oxygen, but adding chloroplast-infused cells could enable oxygen and energy to be supplied through light exposure and photosynthesis.

Researchers studied macaques on a Thai island and found that the animals' unusual habit of washing their food is in fact based on social rank. Dominant monkeys quickly brush their food on their fur before eating it, along with mouthfuls of tooth-degrading sand, while lower-ranked monkeys obsessively wash their food in the surf. Citing the disposable soma hypothesis, the researchers suggest that high-ranking macaques are looking to quickly consume energy to mate and fend off challengers. But food-washing monkeys may be preserving their long-term health to produce more offspring over time. The findings could shed light on how the wear observed in the fossilized teeth of early humans relates to social structure.

These and other new findings about the strain of H5N1 circulating among North American dairy cattle this year come from a set of laboratory experiments. Together, they suggest that exposure to raw milk infected with the currently circulating virus poses a real risk of infecting humans, but that the virus may not spread very far or quickly to others.

They guarantee that all body parts end up where they belong and that no ears grow on our backs. The head-tail axis, for example, determines the orientation of the two ends of the body. It was previously assumed that this axis is largely determined by the interplay between the Nodal and BMP signals. However, there appears to be another player in this system, as researchers have now discovered by using an embryo-like model system they developed. In the absence of BMP, the signalling molecule beta-catenin takes on the role of the Nodal antagonist. This new mechanism could be a flexible solution for axis formation in embryos with different shapes.

The researchers found that activations in the virtual control network accurately predicted neural activity measured from the brains of real rats producing the same behaviors.

New public opinion poll and expert analysis reflect crucial need to make healthy food accessible to avert projected crisis in cardiovascular disease incidence, costs.

A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body structure is not predetermined from the outset. This could enable the species to survive dry periods unscathed.

New research shows that the typical mammalian heater organ, brown fat, evolved exclusively in modern placental mammals. The research team demonstrated that marsupials, our distant relatives, possess a not fully evolved form of brown fat. They discovered that the pivotal heat-producing protein called UCP1 became active after the divergence of placental and marsupial mammals. This finding is crucial for understanding the role of brown fat in mammalian evolution, endothermy, and metabolism.

Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds. Interestingly, the mammalian embryo develops similarly. Scientists now introduce a mathematical framework that analyzes self-organization from a single cell to a multicellular organism.
