Promising Synthetic Heart Valve Developed for Growing Children

June 16, 2023

Researchers at Harvard’s Wass Institute and John A. Paulson School of Engineering and Applied Sciences (SEAS) have made significant progress in developing a synthetic heart valve with potential applications for growing children. Known as FibraValve, this implant can be created in a matter of minutes using a spun-fiber technique that enables the shaping of the valve’s delicate flaps at a microscopic level. The valve is designed to be colonized by the patient’s own living cells, allowing it to develop and grow as the child matures.

FibraValve builds upon the team’s previous creation, JetValve, an artificial heart valve introduced in 2017 that shared similar principles. The updated version incorporates “focused rotary jet spinning,” which utilizes streams of focused air to more rapidly and precisely collect synthetic fibers on a spinning mandrel. This enhancement facilitates finer adjustments to the valve’s shape, enabling the polymer’s micro- and nano-fibers to more accurately mimic the tissue structure of a natural heart valve. The entire manufacturing process can be completed in less than 10 minutes, in contrast to alternative methods that may take hours.

Language Disparity Online: Dominance of English Raises Concerns for Linguistic Diversity

June 16, 2023

The internet has become a global phenomenon, connecting over 5 billion people worldwide, representing approximately 63% of the global population. With such diverse users, speaking thousands of languages, one would expect a multitude of languages to be represented online. However, an analysis by web-scanning firm W3Techs reveals significant discrepancies in language representation on the web. While English dominates as the primary language for over half of all websites, languages like Chinese and Hindi, spoken by billions of people, have minimal online presence.

W3Techs specializes in tracking programming languages used on the internet and categorizes publicly accessible domains accordingly. By comparing their data with language usage statistics from Ethnologue, a renowned authority on global languages, it becomes evident that certain languages are grossly overrepresented while others are virtually absent online. English, German, and Japanese enjoy a much larger share of the internet than their native speakers represent. Conversely, languages outside the European realm struggle to establish a meaningful presence online.

Accelerating Wound Healing: 3D-Printed Ink Unleashes Immune System Vesicles

June 15, 2023

Researchers have made a significant breakthrough in wound healing by developing a specialized ink that actively promotes the body’s healing process. Published in ACS Applied Materials & Interfaces, the study introduces a wound-healing ink that exposes cuts to immune-system vesicles, stimulating the body’s natural healing response. Using a 3D-printing pen, the ink can be applied to wounds of any shape, and in experiments on mice, it demonstrated the ability to nearly completely repair wounds in just 12 days.

When the skin is injured, the body initiates its natural healing mechanisms, involving the clearance of bacteria, regeneration of blood vessels, and eventual formation of a scar. While various techniques support the body’s healing process, they typically complement its inherent abilities. Bandages and stitches control bleeding, while antibiotics prevent infections. However, by incorporating elements that actively aid the body’s construction crew in wound healing, the process could be accelerated.

Caltech Achieves Groundbreaking Space-Based Solar Power Transmission

June 15, 2023

The California Institute of Technology (Caltech) has made a remarkable breakthrough in the field of space-based power by successfully beaming solar power from space to Earth without the need for any physical wires—a significant milestone, according to reports.

This groundbreaking experiment is part of Caltech’s Space Solar Power Project, and the institute recently announced the successful transmission through a press release. Researchers accomplished the power transfer using the Microwave Array for Power-transfer Low-orbit Experiment (MAPLE), a small prototype deployed aboard the in-orbit Space Solar Power Demonstrator (SSPD-1) launched in January. The team achieved a significant feat by transmitting solar power collected in space using microwaves to a receiver on the rooftop of Gordon and Betty Moore Laboratory of Engineering on Caltech’s campus in Pasadena.

Co-director of the Space Solar Power Project, Ali Hajimiri, expressed excitement about the results, stating, “Through the experiments we have run so far, we received confirmation that MAPLE can transmit power successfully to receivers in space. We have also been able to program the array to direct its energy toward Earth, which we detected here at Caltech. We had, of course, tested it on Earth, but now we know that it can survive the trip to space and operate there.”
