Researchers led by Osaka University have shown that a molecule known as ATAD3A is essential for the movement of genetic material inside cellular substructures called mitochondria. Appropriate distribution of this DNA, organized into “nucleoid” structures, is key for the generation of energy by the “respiratory chain” protein complex. This study opens up opportunities for developing new methods to alter nucleoid movement and affect mitochondrial function, thereby providing potential therapies against mitochondrial diseases.

Researchers at Kanazawa University report in ACS Nano the development of a nanoparticle that acts as a heater and a thermometer. Inserting the nanoparticle in living cells results in a heat spot that, by switching it on and off, enables the controlled modulation of local cellular activities.
Schematic illustrations of cargo transport by a swarm of molecular robots (top) and fluorescence images of a molecular robot transporting blue sphere-like cargo (bottom). The scale bar is 20 micrometers. By specifying the position of the light irradiation, it is possible to accumulate the cargo at the designated destination (right). The scale bar is 50 micrometers (Mousumi Akter, et al. Science Robotics. April 20, 2022).

Garden soil houses a variety of bacteria and their natural byproducts — including one that may help halt tumor growth. Lankacidins are molecules that can be isolated from Strepomyces rochei, a common bacterium in soil. In addition to antimicrobial properties, a type of lankacidins, called lankacidin C, can inhibit tumor activity in various cancer cell lines, including leukemia, melanoma, ovarian and breast cancers. Lankacidin C offers a potential foundation on which to design anticancer drugs, but its structure is complicated and difficult to manipulate, according to an international research group. The same group recently identified where antitumor activity is housed on the molecule and has now used that information to simplify lankacidin as a potential starting point to engineer treatments.

Measuring the temperature of objects at a nanometer-scale has been a long challenge, especially in living biological samples, because of the lack of precise and reliable nanothermometers. An international team of researchers has realized a quantum technology to probe temperature on a nanometer-scale, and have observed a ‘fever’ in tiny nematode worms under pharmacological treatment. This strengthens the connection between quantum sensing and biology and ushers in novel thermal imaging technologies in biomedical research.
