A future where injured or diseased organs can be removed and replaced with new lab-printed tissues that are customized specifically for each patient is not as far away as you might think. These functional and living tissues could grow naturally within the body, and repair and sustain themselves over time. While these concepts were once in the realm of science fiction, advances in bioprinting, which is a form of 3D printing using biological “inks” (known as bioinks) loaded with living cells, are bringing them closer to reality. Among the researchers advancing this field is Dr. Mingjun Xie of Zhejiang University, China, and colleagues, who are performing work that addresses a significant challenge in bioprinting. This involves creating large portions of tissues that have a functional vasculature, thereby mimicking the complexity of native tissues and organs.

Data involving angles can be found across a diverse array of scientific fields, but so far, the mathematical tools used to study them have often proved insufficient to detect the complex relationships between different angles within large datasets. Through its research, a team consisting of Professor Christophe Ley and Sophia Loizidou from the University of Luxembourg, Professor Shogo Kato from the Institute of Statistical Mathematics in Tokyo, and Professor Kanti Mardia from the University of Leeds, has developed a new model which overcomes many of these challenges: allowing the researchers to study relationships between three angles at once, as well as mixtures of angles and classical measurements on the line.

For decades, works of science fiction have explored how the universe’s most fundamental speed limit could be broken by warping the fabric of spacetime. Through his experiments, Dr. Chance Glenn, founder of Morningbird Space Corporation, believes he may have discovered how spacetime can be distorted by extreme electric fields, which can be easily created in the lab. If his theory is correct, it would mean that the concept of ‘warp drives’ which allow us to travel at faster than the speed of light could be more feasible than we once thought.

In recent years, rapid advancements in techniques for genetic analysis and manipulation have enhanced our potential to understand and improve crop diversity. An innovative project led by Dr. Pasquale Tripodi of the Italian Council for Agricultural Research and Economics and Dr Sandra Goritschnig of the European Cooperative Programme for Plant Genetic Resources marks a significant advance in the study of lettuce genetics. Their recently published research platforms a highly sophisticated technique to analyse genetic diversity within lettuces called Single Primer Enrichment Technology, or SPET for short. This approach provides a highly detailed view of lettuce genetics and also has significant implications for agricultural resilience and crop selection and breeding.

Dimpled surfaces offer a useful and easily implementable way to reduce friction between lubricated surfaces as they slide over each other. Through cutting-edge simulations, Dr. Robert Tomkowski and colleagues at the KTH Royal Institute of Technology in Sweden explore how the microscale structures of surface dimples can be optimized to minimize friction. Their findings could help to reduce wear in mechanical systems, while also making them more energy efficient.

As an inherently brittle material, concrete often needs to be replaced after just a few decades: driving a demand which incurs significant costs for Earth’s climate. Through their research, Professors Suzanne Scarlata and Nima Rahbar at Worcester Polytechnic Institute, Massachusetts, introduce a new mechanism that allows concrete to quickly repair itself, with the help of an enzyme vital to the function of living cells. This approach could help to reduce the world’s insatiable demand for concrete.
