Stuttgart/Boulder - It is not the first time that spiders have served as biological models in the research field of soft robotics. The hydraulic actuation mechanisms they apply to move their limbs when weaving their web or hunting for prey give them powers many roboticists and engineers have drawn inspiration from.

When someone bumps their elbow against a wall, they not only feel pain but also might experience bruising. Robots and prosthetic limbs don't have these warning signs, which could lead to further injury. Now, researchers reporting in ACS Applied Materials & Interfaces have developed an artificial skin that senses force through ionic signals and also changes color from yellow to a bruise-like purple, providing a visual cue that damage has occurred.
Researchers from the Singapore University of Technology and Design (SUTD) have demonstrated a technology that rapidly detects pollutants in water by measuring their impacts on swimming microorganisms.
Their proof-of-concept, published in Scientific Reports, does not require any chemicals, reagents or laboratory equipment. Instead, it leverages the regular camera of a smartphone as well as microorganisms called Paramecia that are ubiquitous in water bodies--making it especially suitable for assessing water drinkability in underdeveloped regions.
LMU researchers have identified the 14-3-3sigma gene as an important suppressor of carcinogenesis in the gastrointestinal tract.
The lush forests and more than 7,000 islands of the Philippines hold a rich diversity of life, with 258 bird species who live nowhere but the Philippine archipelago. A new study from University of Utah researchers suggests that, due to deforestation and habitat degradation, more bird species may be endangered that previously thought - including species that may not have been discovered yet. The study is published in Frontiers in Ecology and Evolution.
Researchers from the Max-Planck Institute for Terrestrial Microbiology have discovered a surprising asymmetry in the mating behavior of unicellular yeast that emerges solely from molecular differences in pheromone signaling. Their results, published in the current issue of "Science Advances", might shed new light on the evolutionary origins of sexual dimorphism in higher eukaryotes.
HOUSTON — The University of Texas MD Anderson Cancer Center's Research Highlights provides a glimpse into recently published studies in basic, translational and clinical cancer research from MD Anderson experts. Current advances include a new combination therapy for acute myeloid leukemia (AML), a greater understanding of persistent conditions after AML remission, the discovery of a universal biomarker for exosomes, the identification of a tumor suppressor gene in hepatocellular carcinoma (HCC) and characterization of a new target to treat Clostridioides difficile (C.
A new rubber band stretches, but then snaps back into its original shape and size. Stretched again, it does the same. But what if the rubber band was made of a material that remembered how it had been stretched? Just as our bones strengthen in response to impact, medical implants or prosthetics composed of such a material could adjust to environmental pressures such as those encountered in strenuous exercise.
A new paper in the journal Cognition examines the visual complexity of written language and how that complexity has evolved.
Should zoos display legally protected species that have been smuggled out of their range countries? A new study suggests that a pause and rethink may be needed, as it reports that accredited zoos have acquired a rare and legally protected reptile, the earless monitor lizard endemic to Borneo, without any evidence that the animals were legally exported.
Steroid (sex) hormones play a central role in sexual development: They help determine how boys become boys and girls become girls. If these hormones are disrupted during fetal life, it can lead to a string of reproductive disorders at birth and later in life, including malformed genitals and decreased fertility.
An alternate-day intermittent fasting schedule offered less fat-reducing benefits than a matched "traditional" diet that restricts daily energy intake, according to a new, 3-week randomized trial involving 36 participants. The study, which is one of the first to tease apart the effects of fasting and daily energy restriction in lean individuals, indicates that alternate-day fasting may offer no fasting-specific health or metabolic benefits over a standard daily diet. However, the authors caution that longer studies with larger groups are needed.
We've seen robots take to the air, dive beneath the waves and perform all sorts of maneuvers on land. Now, researchers at UC Santa Barbara and Georgia Institute of Technology are exploring a new frontier: the ground beneath our feet. Taking their cues from plants and animals that have evolved to navigate subterranean spaces, they've developed a fast, controllable soft robot that can burrow through sand. The technology not only enables new applications for fast, precise and minimally invasive movement underground, but also lays mechanical foundations for new types of robots.
Do you like the thick brush strokes and soft color palettes of an impressionist painting such as those by Claude Monet? Or do you prefer the bold colors and abstract shapes of a Rothko? Individual art tastes have a certain mystique to them, but now a new Caltech study shows that a simple computer program can accurately predict which paintings a person will like.
