Self-assembling, highly conductive sensors could improve wearable devices
To advance soft robotics, skin-integrated electronics and biomedical devices, researchers have developed a 3D-printed material that is soft and stretchable -- traits needed for matching the properties of tissues and organs -- and that self-assembles. Their approach employs a process that eliminates many drawbacks of previous fabrication methods, such as less conductivity or device failure, the team said.
Dampening the 'seeds' of hurricanes
Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study.

Layers of carbonate provide insight into the world of the ancient Romans
Archaeologists face a major challenge when they intend to acquire information about buildings or facilities of which only ruins remain. This was a particular challenge for the remnants of the Roman water mills in Barbegal in Southern France, dating back to the 2nd century CE. This unique industrial complex consisted of 16 water wheels placed in parallel rows. Little could at first be deduced about the site from these now scant ruins -- except that the wheels were supplied by an aqueduct that brought water from the surrounding hills. Researchers have now unraveled the history of the mill complex using calcium carbonate deposits that are now stored in the Archaeological Museum of Arles. These deposits had formed towards the end of the roughly 100-year operational life of the Barbegal water mills on the sides and base of the wooden supply system that conveyed the water to the wheels.
Finding the sweet spot in brain development
Short-lived neural connections in the mouse brain help prime sensory circuits, forever affecting the mouse's sense of touch. Neuroscientists have discovered that a receptor protein named mGluR1 helps regulate the timing of these temporary connections. Their findings may help reveal the origins of various neurodevelopmental disorders and new ways of treating them.
Researchers identify unique survival strategies adopted by fish in the world's warmest waters
A team of researchers have identified unexpected ways coral reef fish living in the warmest waters on earth, in the Arabian Gulf, have adapted to survive extreme temperatures.
Portable engine powers artificial muscles in assistive devices
Researchers have developed a lightweight fluidic engine to power muscle-mimicking soft robots for use in assistive devices. What sets the new engine apart is its ability to generate significant force without being tethered to an external power source.
Degradation of cell wall key in the spread of antibiotic resistance
A study provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria's protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics.
Multiple myeloma: Early detection of aggressive tumors
Multiple myeloma is one of the most common forms of cancer of the immune cells in the bone marrow. It is considered incurable. Even when patients respond to treatment at first, the cancer comes back. To be able to intervene faster and on a more targeted basis, researchers completed a comprehensive study of this disease at the molecular level.
Scientists probe chilling behavior of promising solid-state cooling material
A research team has bridged a knowledge gap in atomic-scale heat motion. This new understanding holds promise for enhancing materials to advance an emerging technology called solid-state cooling.
New findings may fix the replicability crisis in microbiome research
Researchers have discovered another factor that affects the composition of the gut microbiome: time of day.
Largest ever genetic study of age of puberty in girls shows links with weight gain
Genes can indirectly influence the age at which girls have their first period by accelerating weight gain in childhood, a known risk factor for early puberty. Other genes can directly affect age of puberty, some with profound effects.
Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Melanin from cuttlefish ink as a sustainable biomass resource
Melanin is a ubiquitous compound in nature, produced by many organisms. However, its potential as a biomass resource to produce value-added chemicals and materials remains relatively unexplored. In a recent study, researchers investigated the chemical decomposition of melanin derived from cuttlefish ink and showcased its application in the synthesis of biopolymer films and particles. Their efforts will hopefully pave the way to the adoption of melanin upcycling.
Novel blood test helps improve cancer treatments
Oncologists use biopsy and imaging techniques to diagnose and monitor tumor diseases and assess treatment success. Researchers have further developed an advanced method to analyze liquid biopsies of DNA fragments in the blood. The new method is fast and practical, without putting much of a strain on patients. This could make it possible to provide diagnostics and treatments that are more closely tailored to individual patients in the future.
