Participating in genetic studies is in your genes      (via sciencedaily.com)     Original source 

Why do some people take part in genetic studies while others do not? The answer may lie within our genetic makeup. According to a groundbreaking study, people who participate in genetic studies are genetically more likely to do so, leaving detectable 'footprints' in genetics data. This breakthrough equips researchers with the ability to identify and address participation bias, a significant challenge in genetic research.

Surgical and engineering innovations enable unprecedented control over every finger of a bionic hand      (via sciencedaily.com) 

For the first time, a person with an arm amputation can manipulate each finger of a bionic hand as if it was his own. Thanks to revolutionary surgical and engineering advancements that seamlessly merge humans with machines, this breakthrough offers new hope and possibilities for people with amputations worldwide. A study presents the first documented case of an individual whose body was surgically modified to incorporate implanted sensors and a skeletal implant. A.I. algorithms then translated the user's intentions into movement of the prosthesis.

Pump powers soft robots, makes cocktails      (via sciencedaily.com) 

Over the past several years, researchers have been developing soft analogues of traditionally rigid robotic components. In fluid-driven robotic systems, pumps control the pressure or flow of the liquid that powers the robot's movement. Most pumps available today for soft robotics are either too large and rigid to fit onboard, not powerful enough for actuation or only work with specific fluids. Researchers have now developed a compact, soft pump with adjustable pressure flow versatile enough to pump a variety of fluids with varying viscosity, including gin, juice, and coconut milk, and powerful enough to power soft haptic devices and a soft robotic finger.

Training robots how to learn, make decisions on the fly      (via sciencedaily.com)     Original source 

Mars rovers have teams of human experts on Earth telling them what to do. But robots on lander missions to moons orbiting Saturn or Jupiter are too far away to receive timely commands from Earth. Researchers developed a novel learning-based method so robots on extraterrestrial bodies can make decisions on their own about where and how to scoop up terrain samples.

Crawford Lake, Canada, chosen as the primary marker to identify the start of the Anthropocene epoch      (via sciencedaily.com)     Original source 

An international team of researchers has chosen the location which best represents the beginnings of what could be a new geological epoch, the Anthropocene. The Anthropocene Working Group have put forward Crawford Lake, in Canada, as a Global Boundary Stratotype Section and Point (GSSP) for the Anthropocene. A GSSP is an internationally agreed-upon reference point to show the start of a new geological period or epoch in layers of rock that have built up through the ages.

Capturing the immense potential of microscopic DNA for data storage      (via sciencedaily.com)     Original source 

A 'biological camera' bypasses the constraints of current DNA storage methods, harnessing living cells and their inherent biological mechanisms to encode and store data. This represents a significant breakthrough in encoding and storing images directly within DNA, creating a new model for information storage reminiscent of a digital camera. Led by Principal Investigator Associate Professor Chueh Loo Poh from the College of Design and Engineering at the National University of Singapore, and the NUS Synthetic Biology for Clinical and Technological Innovation (SynCTI), the team's findings, which could potentially shake up the data-storage industry, were published in Nature Communications on 3 July 2023.

Revolutionary self-sensing electric artificial muscles      (via sciencedaily.com) 

Researchers have made groundbreaking advancements in bionics with the development of a new electric variable-stiffness artificial muscle. This innovative technology possesses self-sensing capabilities and has the potential to revolutionize soft robotics and medical applications. The artificial muscle seamlessly transitions between soft and hard states, while also sensing forces and deformations. With flexibility and stretchability similar to natural muscle, it can be integrated into intricate soft robotic systems and adapt to various shapes. By adjusting voltages, the muscle rapidly changes its stiffness and can monitor its own deformation through resistance changes. The fabrication process is simple and reliable, making it ideal for a range of applications, including aiding individuals with disabilities or patients in rehabilitation training.
