Scientists untangle the challenging complexities of radiocarbon in ice cores

Scientists untangle the challenging complexities of radiocarbon in ice cores

ANSTO scientists, Dr. Andrew Smith, Dr. Quan Hua and Dr. Bin Yang have contributed to a paper that elucidates how in situ cosmogenic radiocarbon (14C) is produced, retained and lost in the top layer of compacting snow (the "firn layer") and the shallow ice below at an ice accumulation site in Greenland.

Leveraging skyscraper architecture: New design enhances porosity and structural stability for metal-organic frameworks

Leveraging skyscraper architecture: New design enhances porosity and structural stability for metal-organic frameworks

The Burj Khalifa, the tallest building in the world, employs advanced construction techniques designed to withstand wind, seismic activity, and its own massive weight. Among these techniques is the "Meta Column System," which plays a pivotal role by strategically positioning large columns to resist lateral forces, thereby facilitating the construction of such a towering structure.

Team achieves successful reproduction of hematopoietic stem cell developmental process in an in vitro culture system

Team achieves successful reproduction of hematopoietic stem cell developmental process in an in vitro culture system

Researchers at Kumamoto University have achieved a notable advancement in stem cell biology by reproducing the developmental process of hematopoietic stem cells (HSCs) in vitro. This culture system not only enhances our understanding of how HSCs develop but also leads to the development of a new tool that could be instrumental in stem cell therapy and blood disease treatments in the future.

Team develops promising new form of antibiotic that makes bacterial cells self-destruct

Team develops promising new form of antibiotic that makes bacterial cells self-destruct

To address the global threat of antibiotic resistance, scientists are on the hunt for new ways to sneak past a bacterial cell's defense system. Taking what they learned from a previous study on cancer, researchers from the University of Toronto (U of T) have developed novel compounds that trigger bacterial cells to self-destruct.

New strategy unlocks magnetic switching with hydrogen bonding at molecular level

New strategy unlocks magnetic switching with hydrogen bonding at molecular level

A research team from Kumamoto University has successfully developed a new approach to create switchable magnetic materials by using hydrogen bonding at the molecular level. Their study shows how certain metal complexes, previously unresponsive to external stimuli, can now exhibit sharp and complete magnetic transitions by introducing chiral hydrogen bonds.

Uncovering new regulatory mechanisms in embryo implantation

Uncovering new regulatory mechanisms in embryo implantation

Implantation is the initial step in pregnancy, where the embryo attaches to and enters the endometrium, the inner tissue layer of the uterus. During this process, the cells of the endometrium change to build the right conditions for the fertilized egg to develop.

Cellular senescence research identifies key enzyme to promote healthy aging

Cellular senescence research identifies key enzyme to promote healthy aging

A team at Kumamoto University has made a discovery that could help promote healthy aging. As the world's population ages, Japan's aging population in particular is growing at an unprecedented rate, making it crucial to extend healthy lifespans rather than just lifespans.

Controlling sound waves with Klein tunneling improves acoustic signal filtration

Controlling sound waves with Klein tunneling improves acoustic signal filtration

In the context of sensory modalities, eyes work like tiny antennae, picking up light, electromagnetic waves traveling at blistering speeds. When humans look at the world, their eyes catch these waves and convert them into signals the brain reads as colors, shapes, and movement. It's a seamless process, that allows people to see details clearly even when there's a lot happening around them.
