Coating implantable electronics in the polymer PEDOT can extend their life, which could make cyborgs more common in the future.
Researchers have developed a special polymer coating for electronics implants that make them less abrasive to biological tissue.
In January 2019, China made history by becoming the first country to land a spacecraft on the far side of the moon. As part of this mission, the Chang’e-4 lunar rover carried a small biosphere with six living organisms, including cotton seeds. While the other plants in the biosphere died quickly, the cotton seeds produced a small plant, which grew two leaves before it died. Researchers then created a 3D simulation of the cotton plant using data from the experiment, which revealed that the cotton plant grew much better than expected before it died from the cold.
This experiment marked the first time that humans have attempted to grow plants on the moon. Growing plants in space is an important part of NASA’s vision of long-term space travel. If astronauts are to embark on missions lasting months or years, they will need fresh produce to supplement their diet. While vitamins and other supplements are effective for short-term missions, the nutrients in supplements and ready-made meals can break down over time. Radiation in space can speed up this process. In addition, fresh vegetables would give astronauts more nutrients and improve the taste of their food. Furthermore, growing plants in space would enable astronauts to have access to fresh, uncooked food, reducing their reliance on pre-cooked meals.
However, growing plants in space is not just about ensuring astronauts have access to fresh food. NASA is also interested in how growing plants can impact the psychological well-being of astronauts. Studies have shown that access to plants and green spaces can have a positive impact on mental health, and astronauts on the International Space Station have reported that fresh flowers and gardens can create a beautiful atmosphere and make them feel more connected to Earth.

Imagine having a building made of stacks of bricks connected by adaptable bridges. You pull a knob that modifies the bridges and the building changes functionality. Wouldn’t it be great?
A team of researchers led by Prof. Aitor Mugarza, from the Catalan Institute of Nanoscience and Nanotechnology (ICN2) and ICREA, together with Prof. Diego Peña from the Center for Research in Biological Chemistry and Molecular Materials of the University of Santiago de Campostela (CiQUS-USC), Dr. Cesar Moreno, formerly a member of ICN2’s team and currently a researcher at the University of Cantabria, and Dr. Aran Garcia-Lekue, from the Donostia International Physics Center (DIPC) and Ikerbasque Foundation, has done something analogous, but at the single-atom scale, with the aim of synthesizing new carbon-based materials with tunable properties.
As explained in a paper just published in the Journal of the American Chemical Society (JACS) and featured on the cover of the issue, this research is a significant breakthrough in the precise engineering of atomic-thin materials —called “2D materials” due to their reduced dimensionality. The proposed fabrication technique opens exciting new possibilities for materials science, and, in particular, for application in advanced electronics and future solutions for sustainable energy.
In recent decades, engineers have created a wide range of robotic systems inspired by animals, including four legged robots, as well as systems inspired by snakes, insects, squid and fish. Studies exploring the interactions between these robots and their biological counterparts, however, as still relatively rare.
Researchers at Peking University and China Agricultural University recently set out to explore what happens when live fish are placed in the same environment as a robotic fish. Their findings, published in Bioinspiration & Biomimetics, could both inform the development of fish-inspired robots and shed some new light on the behavior of real fish.
“Our research team has been focusing on the development of self-propelled robotic fish for a considerable amount of time,” Dr. Junzhi Yu, one of the researchers who carried out the study, told Tech Xplore. “During our field experiments, we observed an exciting phenomenon where live fish were observed following the swimming robotic fish. We are eager to further explore the underlying principles behind this phenomenon and gain a deeper understanding of this ‘fish following’ behavior.”

Three university teams will explore and take initial steps to mitigate risks associated with manufacturing capabilities that rely on biological processes in space. The DARPA Biomanufacturing: Survival, Utility, and Reliability beyond Earth (B-SURE) program aims to address foundational scientific questions to determine how well industrial bio-manufacturing microorganisms perform in space conditions.
Cell division is a standard biological process we all learned about in high school. While this process becomes more complex with more advanced study, there | Immunology.
In a new study in Nature Machine Intelligence, researchers Bojian Yin and Sander Bohté from the HBP partner Dutch National Research Institute for Mathematics and Computer Science (CWI) demonstrate a significant step towards artificial intelligence that can be used in local devices like smartphones and in VR-like applications, while protecting privacy.
They show how brain-like neurons combined with novel learning methods enable training fast and energy-efficient spiking neural networks on a large scale. Potential applications range from wearable AI to speech recognition and Augmented Reality.
While modern artificial neural networks are the backbone of the current AI revolution, they are only loosely inspired by networks of real, biological neurons such as our brain. The brain however is a much larger network, much more energy-efficient, and can respond ultra-fast when triggered by external events. Spiking neural networks are special types of neural networks that more closely mimic the working of biological neurons: the neurons of our nervous system communicate by exchanging electrical pulses, and they do so only sparingly.

Shamees Aden, a British designer and scientist, has come up with a concept for a pair of self-repairing shoes of synthetic protocell materials.
Protocells are molecules that on their own are not alive, but when used with other types of protocells can mimic the properties of living organisms. They react to heat, light and pressure like live cells.
Aden’s concept for the shoes is that they could be 3D printed to the exact size of the wearer and when worn the shoes would react to heat and pressure to grow and expand in pressure points where more cushioning is needed. They would be kept in protocell fluid overnight to regenerate.
Mathematicians have uncovered a universal explanatory framework that provides a “window into evolution.” This framework explains how molecules interact with each other in adapting to changing conditions while still maintaining tight control over essential properties that are crucial for survival.
According to Dr. Araujo from the QUT School of Mathematical Sciences, the research results provide a blueprint for the creation of signaling networks that are capable of adapting across all life forms and for the design of synthetic biological systems.
“Our study considers a process called robust perfect adaptation (RPA) whereby biological systems, from individual cells to entire organisms, maintain important molecules within narrow concentration ranges despite continually being bombarded with disturbances to the system,” Dr. Araujo said.
