Stronger tape engineered through the art of cutting      (via sciencedaily.com)     Original source 

What if you could make adhesives both strong and easily removable? This seemingly paradoxical combination of properties could dramatically change applications in robotic grasping, wearables for health monitoring, and manufacturing for assembly and recycling. A team has adapted kirigami, the ancient Japanese art of cutting paper, into a method for increasing the adhesive bond of ordinary tape by 60 times. Developing such adhesives may not by that far off through the latest research conducted by the team of Michael Bartlett, assistant professor in the Department of Mechanical Engineering at Virginia Tech, and published in Nature Materials on June 22.

A roadmap for gene regulation in plants      (via sciencedaily.com)     Original source 

For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and identifies a new library of DNA parts that can be used to optimize plants for bioenergy and agriculture.

'Shoebox' satellites help scientists understand trees and global warming      (via sciencedaily.com)     Original source 

As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental scientists make more precise measurements about trees' response to a warming climate.

How will a warming world impact the Earth's ability to offset our carbon emissions?      (via sciencedaily.com)     Original source 

New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.

Metamaterials with built-in frustration have mechanical memory      (via sciencedaily.com)     Original source 

Researchers have discovered how to design materials that necessarily have a point or line where the material doesn't deform under stress, and that even remember how they have been poked or squeezed in the past. These results could be used in robotics and mechanical computers, while similar design principles could be used in quantum computers.

Hybrid AI-powered computer vision combines physics and big data      (via sciencedaily.com)     Original source 

Researchers have laid out a new approach to enhance artificial intelligence-powered computer vision technologies by adding physics-based awareness to data-driven techniques. The study offered an overview of a hybrid methodology designed to improve how AI-based machinery sense, interact and respond to its environment in real time -- as in how autonomous vehicles move and maneuver, or how robots use the improved technology to carry out precision actions.

Team finds reliable predictor of plant species persistence, coexistence      (via sciencedaily.com)     Original source 

Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.
