Towards a new era in flexible piezoelectric sensors for both humans and robots

12/06/2024
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.

AI better detects prostate cancer on MRI than radiologists

12/06/2024
AI detects prostate cancer more often than radiologists. Additionally, AI triggers false alarms half as often. This was a large-scale study where an international team transparently evaluated and compared AI with radiologist assessments and clinical outcomes.

Breakthrough in next-generation memory technology!

12/06/2024
Scientists maximize the efficiency of hafnia-based ferroelectric memory devices.

Age is just a number: Immune cell 'epigenetic clock' ticks independently of organism lifespan

12/06/2024
Researchers use epigenetic clock, DNA methylation and mouse model to demonstrate that T cell proliferation can stretch past organism lifespan and acuta lymphoblastic leukemia T cells appear hundreds of years old.

Site new care homes near trees and away from busy roads to protect residents' lungs

12/06/2024
To shield older residents from dangerous air pollution, new care homes should be built as far from heavy traffic as possible, according to a new study.

Cocaine trafficking threatens critical bird habitats

12/06/2024
In addition to its human consequences, cocaine trafficking harms the environment and threatens habitats important to dozens of species of migratory birds, according to a new study.

Humans are the elephant in the room where conservation is debated

12/06/2024
Studies working to map conservation historically have left humans out of the equation. This study proposes ways to build in the outsized footprint created by people in wild places.

No bones about it: 100-million-year-old bones reveal new species of pterosaur

12/06/2024
New research has identified 100-million-year-old fossilized bones discovered in western Queensland as belonging to a newly identified species of pterosaur, which was a formidable flying reptile that lived among the dinosaurs.

Uncovering the nature of emergent magnetic monopoles

12/06/2024
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.

Are plants intelligent? It depends on the definition

12/06/2024
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?

Nasal microbiota is potential diagnostic biomarker for sepsis

12/06/2024
A new study shows that analyzing nasal microbiota outperforms gut microbiota analysis to predict sepsis in the ICU.

Boosting CAR-T cell therapies from under the skin

12/06/2024
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.

An AI-powered wearable system tracks the 3D movement of smart pills in the gut

12/06/2024
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.

Study shows role of fathers in seeding the microbiota of newborns and confirms benefits of maternal fecal microbiota transplants

12/06/2024
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.

AI-powered simulation training improves human performance in robotic exoskeletons

12/06/2024
Researchers have demonstrated a new method that leverages artificial intelligence (AI) and computer simulations to train robotic exoskeletons to autonomously help users save energy while walking, running and climbing stairs.

New technique reveals earliest signs of genetic mutations

12/06/2024
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.

Origin and spread of malaria

12/06/2024
Researchers have reconstructed the evolutionary history and global spread of malaria over the past 5,500 years, identifying trade, warfare, and colonialism as major catalysts for its dispersal.

Ritual sacrifice at Chichén Itzá

12/06/2024
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.

Just thinking about a location activates mental maps in the brain

12/06/2024
Researchers found that mental representations known as cognitive maps, located in the hippocampus and entorhinal cortex, are activated when the brain performs mental simulations of a navigational route.

Obesity-cancer connection discovery suggests strategies for improving immunotherapy

12/06/2024
Immune system cells called macrophages play an unexpected role in the complicated connection between obesity and cancer. The findings provide a mechanistic explanation for how obesity can contribute to both increased cancer risk and enhanced responses to immunotherapy.
