Researchers at The University of Tokyo develop a method of culturing meat in the laboratory in the form of millimeter-scale contractile beef muscle that closely simulates steak meat

An international team led by Professor Yilin Wu, Associate Professor of the Department of Physics at The Chinese University of Hong Kong (CUHK) has made a novel conceptual advance in the field of active matter science. The team discovered a new route in which the self-organisation of active fluids in space and time can be controlled by a single material property called viscoelasticity. This new finding may pave the way for fabricating a new class of self-driven devices and materials, such as the ability to control the rhythmic movement of soft robots without relying on electronic circuits, and for the study of microbial physiology. It has been published in the scientific journal Nature.

Undergraduate students explore a more efficient way to measure protein-containing vessels released by cells

Researchers from DGIST have now found a way to keep living, wet cells viable in an ultra-high-vacuum environment, using graphene, allowing—like never before—accurate high-resolution visualization of the undistorted molecular structure and distribution of lipids in cell membranes. This could enhance our bioimaging abilities considerably, improving our understanding of mechanisms underlying complex diseases such as cancers and Alzheimer’s

In a study published in Gastroenterology – Researchers at Osaka City University and The Institute for Medical Science, The University of Tokyo, in collaboration with Brigham and Women's Hospital in Boston, report the intestinal bacterial and viral metagenome information from the fecal samples of patients with recurrent Clostridioides difficile infection (rCDI). This comprehensive analysis reveals the bacteria and phages involved in pathogenesis in rCDI, and their remarkable pathways important for the recovery of intestinal flora function.

Tissue stem cells can self-renew and differentiate, supplying cells necessary for tissues at various developmental stages. However, detailed analysis in vivo is difficult, so the molecular mechanisms underlying the stemness of gastric tissue stem cells have remained a mystery. Here, by using organoids that mimic tissue structure and function in vivo and GeCKO screening to inactivate arbitrary genes, Alk, Bclaf3 and Prkra have been identified as genes regulating stemness.

New ‘armoured’ T cells attack cancer without being suppressed by drugs given to transplant patients to avoid organ rejection.

Osaka City University unravels the atomic architecture of the “Nap” protein complex found on Mycoplasma pneumoniae.

Researchers at Kanazawa University report in Nature Communications the mechanism making some lung-cancer patients resistant to the drug osimertinib. In addition, they suggest a combined drug treatment resolving osimertinib resistance in the case of cancer cells expressing low amounts of AXL, a protein belonging to the class of receptor tyrosine kinases.

Scientists are learning about species adaptation by comparing their stem cell-related genes.

While scientists still don’t fully understand the diverse nature of RNA molecules, it is believed that the proteins binding to them, called RNA-binding proteins, are associated with many disease formation. A research led by biomedical scientists from City University of Hong Kong (CityU) has developed a novel detection method, called CARPID, to identify binding proteins of specific RNAs in the living cells. It is expected the innovation can be applied in various cell research, from identifying biomarkers of cancer diagnosis to detecting potential drug targets for treating viral diseases.

Scientists demonstrate that the information about host bacteria–bacteriophage (phage) associations derived from world’s first metagenome analysis is useful for the development of phage therapies against intestinal pathobionts.

Researchers at Kanazawa University report in Biomaterials a high-speed atomic-force microscopy study of protein filaments in the nuclear pore complex. The visualization in real-time of the filaments’ dynamics is an important step in our understanding of molecular transport mechanisms between a cell nucleus and its surrounding medium.

A transparent container made by Nagoya University researchers allows easy and quick grafting of very young plants, with benefits for agriculture and plant research.

The newly developed rapid testing kit detects COVID-19 antibodies, requiring only micro-liter volume of serum and 15 minutes of time for achieving results.

Researchers at Kanazawa University report in the Journal of Thoracic Oncology a promising novel approach for a combined treatment of the most common type of lung cancer and associated secondary cancers in the central nervous system. The approach lies in combining two cancer drugs, with one compensating for a resistance side effect of the other.

The way research in bioprinting will be taken forward has been laid out in this roadmap for the field.

Researchers at Tohoku University have developed a new type of smart contact lenses that can prevent dry eyes. The self-moisturising system, which is described in the journal Advanced Materials Technologies, maintains a layer of fluid between the contact lens and the eye using a novel mechanism.

Using tissue engineering techniques, researchers are developing living heart valves that can grow after implantation in the human heart.

Malaria parasites transform healthy red blood cells into rigid versions of themselves that clump together, hindering the transportation of oxygen. The infectious disease affects more than 200 million people across the world and causes nearly half a million deaths every year, according to the World Health Organization’s 2018 report on malaria. Until now, however, researchers did not have a strong understanding of how the parasite so effectively infiltrated a system’s red blood cells.

Husband and wife team, Kimishige (3 December 1925 – 6 July 2018) and Teruko Ishizaka (28 September 1926 – 4 June 2019) discovered the antibody class Immunoglobulin E (IgE) that triggers allergic reactions.

A team of researchers from City University of Hong Kong (CityU) and Karolinska Institutet has recently developed a new protein which can help increase the targeting accuracy in the genome editing process.
