Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, researchers tackled these issues by developing a novel piezoelectric composite material made from electrospun polyvinylidene fluoride nanofibers combined with dopamine. Sensors made from this material showed significant performance and stability improvements at a low cost, promising advancements in medicine, healthcare, and robotics.

To understand the unique physical phenomena associated with the properties of magnetic hedgehogs and antihedgehogs, which behave as virtual magnetic monopoles and antimonopoles respectively, it is essential to study their intrinsic excitations. In a new study, researchers revealed the dynamical nature of collective excitation modes in hedgehog lattices in itinerant chiral magnets. Their findings serve as the foundation for studying the dynamics of emergent magnetic monopoles in magnets.

Goldenrod can perceive other plants nearby without ever touching them, by sensing far-red light ratios reflected off leaves. When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby. Is this kind of flexible, real-time, adaptive response a sign of intelligence in plants?

CAR-T cell therapies are transforming the treatment of previously incurable blood cancers, but a large proportion of patients still responds only poorly or not at all to them, calling for new strategies to overcome this challenge. Now, a research team has developed a simple intervention in the form of a biodegradable scaffold material called 'T-cell enhancing scaffolds' (TES) that can be locally injected under the skin and used to restimulate CAR-T cells after their administration. This increased their therapeutic efficacy and significantly curbed tumor growth and prolonged animal survival in an aggressive mouse lymphoma model.

Scientists have developed an artificial intelligence (AI)-powered system to track tiny devices that monitor markers of disease in the gut. Devices using the novel system may help at-risk individuals monitor their gastrointestinal (GI) tract health at home, without the need for invasive tests in hospital settings.

A mother's contribution to the makeup of a newborn baby's microbiota has been well documented. Now a new article shows the important contributions that fathers make to the composition of microorganisms colonizing a baby's gut as well. Furthermore, the study confirmed that maternal fecal microbiota transfer (FMT) in babies born by caesarean section can help to correct the microbiota disturbances often observed in babies who are not born vaginally.

Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including cancer. Now, a new study introduces an original technique, called HiDEF-seq, that can accurately detect the early molecular changes in DNA code that precede mutations.

Rising to power in the wake of the Classic Maya collapse, Chich n Itz was among the largest and most influential cities of the ancient Maya, but much about its political connections and ritual life remain poorly understood. Close kin relationships, including two pairs of identical twins, suggests a connection to the Maya origin myths of the Popol Vuh. Further comparison to Maya populations today reveals the genetic impact of colonial-era epidemics.
