A team of researchers from the University of Melbourne’s Caruso Nanoengineering Group has developed an innovative drug delivery system with significant potential to revolutionize drug development. The new system, known as a metal–biomolecule network (MBN), consists of a coordination network made up entirely of metal ions and biomolecules, eliminating the need for complex drug “carriers.” This breakthrough could offer a simpler, more efficient, and safer alternative for a wide range of biomedical applications.

Published in Science Advances, the research was led by Melbourne Laureate Professor and NHMRC Leadership Fellow Frank Caruso, from the Department of Chemical Engineering, along with Research Fellows Dr. Wanjun Xu and Dr. Zhixing Lin, who share first authorship. The MBN nanoparticles are created by combining non-toxic metal ions (such as calcium and iron, which are naturally absorbed through the diet) with phosphonate biomolecules like DNA. These nanoparticles are chemically and metabolically stable, and have demonstrated antiviral, antibacterial, antifungal, anti-inflammatory, and anti-cancer properties.

Mitochondria, the powerhouse of the cell, are critical in regulating cellular functions such as growth, survival, and energy production. Due to their central role in cancer cell metabolism, these organelles have become key targets for innovative cancer therapies. Mitochondrial genetics and metabolism contribute significantly to cancer progression, influencing processes like cell motility, invasion, and the tumor microenvironment. Despite these promising insights, the development of therapies targeting mitochondria has faced significant hurdles.

Current mitochondrial-targeted treatments, such as mitocans and mitochondriotoxics, focus on disrupting key signaling pathways and proteins involved in cellular energy processes, including hexokinase and Bcl2 family proteins. However, the presence of mutations in cancer cells limits the long-term effectiveness of these therapies, making it difficult to achieve sustained clinical success. A promising advancement in the field is mitochondrial optogenetics (mOpto), a technique that introduces light-gated channelrhodopsins into mitochondria, enabling controlled depolarization of the mitochondrial membrane potential (∆Ψm) and subsequent cell death. While this technology showed promise, its reliance on external light sources restricts its application to surface-level tumors.

Australian company SPEE3D has successfully proven that its XSPEE3D technology for additive manufacturing of metal parts operates efficiently in extremely cold environments. As part of the U.S. Department of Defense’s “Point of Need Challenge” project, the company demonstrated that metal components produced in sub-arctic temperatures exhibit material properties comparable to those created under standard laboratory conditions.

The project aimed to assess manufacturing technologies capable of producing and repairing large metal parts in extreme climates. SPEE3D’s successful demonstration took place at the U.S. Army’s Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, New Hampshire, at the end of 2023. The initiative was carried out in collaboration with the New Jersey Institute of Technology’s (NJIT) COMET project, Philips Federal, and the LIFT innovation platform in Detroit.

Gameto has achieved a historic milestone in reproductive health with the world’s first live human birth using Fertilo, a cutting-edge ovarian support cell (OSC) technology. The groundbreaking birth took place at Santa Isabel Clinic in Lima, Peru, and could represent a significant leap forward in fertility management.

Traditional in vitro fertilization (IVF) methods require women to undergo 10–14 days of high-dose hormonal injections to mature eggs. In contrast, Fertilo uses engineered, young ovarian support cells to replicate the natural egg maturation process outside the body. This innovative technology reduces the need for up to 80% fewer hormone injections compared to traditional IVF and shortens treatment cycles to just three days.

Japanese researchers have demonstrated that freeze-dried mouse sperm can remain viable on the International Space Station (ISS) for extended periods, producing healthy offspring despite exposure to space radiation levels 100 times higher than Earth’s.

Led by Professor Teruhiko Wakayama at the University of Yamanashi, the research shows promise for preserving genetic materials in space long-term. The team’s freeze-dried sperm, stored on the ISS for nearly six years, successfully produced healthy “space pups” with no genetic abnormalities.

Research reveals biomethane as a promising alternative to natural gas in ammonia production, offering potential carbon negativity while maintaining compatibility with existing infrastructure.

Environmental engineer Aurelian Istrate’s research demonstrates that biomethane, derived from food waste and agricultural residues, can replace natural gas in ammonia synthesis. Unlike natural gas, biomethane’s carbon emissions are offset by recent atmospheric CO2 capture during biomass growth.

Scientists at Penn State have demonstrated precise control over material properties through “atomic spray painting” of potassium niobate using molecular beam epitaxy (MBE). The technique, detailed in Advanced Materials, allows for exceptional control through strain tuning—modifying a material’s properties by manipulating its atomic structure.

The team achieved a first by growing potassium niobate using MBE, which deposits atomic layers onto a substrate. By creating strain through template-guided growth, they enhanced the material’s ferroelectric properties. Even a 1% strain produced pressure effects impossible to achieve through external forces.

Climate change is causing widespread bleaching and death among the world’s coral reefs due to rising sea temperatures. In response, Dr. Benyamin Rosental of Ben-Gurion University of the Negev and his team have proposed an innovative potential solution: transplanting stem cells from resilient corals to revive vulnerable ones.

In a recent paper published in Cell Reports, Dr. Rosental, along with Shani Talice and their colleagues, demonstrated for the first time the feasibility of transplanting stem cells into sea anemones, close relatives of corals. Their research showed that stem cells from hexacorallia (Nematostella vectensis) successfully integrated, differentiated, and proliferated in transplanted individuals.
