For cells to function properly, they must produce the right amount of each protein. It is a delicate balance: both too little and too much can compromise essential cellular functions. A team from the University of Geneva (UNIGE) has now shown that even a modest excess of tubulin – the protein that assembles into microtubules, the cell's internal scaffolding – is enough to disrupt tissue architecture and reduce cell viability. Published in Nature Communications, the study demonstrates that the quantity of a protein is just as important as its function.

Researchers have developed a cutting-edge approach to treating glioblastoma, the most common and deadliest brain cancer, that could overcome the limitations of existing drugs.

A Ramsey-based diamond quantum magnetometer developed by researchers at Science Tokyo enables highly sensitive biomagnetic measurements without compromising thermal safety. Using a low-power laser, a light-trapping diamond waveguide, and a compact microwave antenna, the temperature rise in the sensor is just 13 K with a sensor-to-sample distance of 2 mm, enabling detection of picotesla-level (10^-12 T) magnetic fields. The sensor enables safe, close-proximity biomagnetic measurements for future magnetocardiography and magnetoencephalography applications.

Insilico Medicine (“Insilico”, HKEX:3696), a clinical-stage, generative AI-driven drug discovery company, is addressing this critical unmet need by using AI to uncover novel biological mechanisms and develop innovative therapies. The company recently announced the nomination of ISM9528 as a Preclinical Candidate Compound (PCC) for pain management. Identified by PandaOmics, ISM9528 is a potential first-in-class, brain-penetrant, orally available inhibitor of Target Z that offers a novel, non-opioid treatment approach by acting on a previously unexplored biological mechanism. Notably, this marks the 31st PCC nominated by Insilico since 2021, further validating the company’s AI-driven R&D capabilities.

Directed rotational motion is widespread in nature and technology.  At small scales, however, it is difficult to generate. . Researchers from the Karlsruhe Institute of Technology (KIT) and partners in China are now presenting a mechanism in which flows at a water surface alone can cause a floating object to rotate controllably in a single direction. Using this mechanism, they assembled ultrathin fibers into structured bundles – for example to produce low-loss high-frequency transmission lines or surgical suture. The findings were published in Science Advances. (DOI: 10.1126/sciadv.aed5495)

Hepatocytes, the primary functional cells of the liver, release soluble Tim-3 protein during drug-induced injury, and this protein acts as a protective feedback signal to limit excessive immune cell infiltration in the liver. A new study reveals that hepatocyte-derived sTim-3 could bind to Galectin-3 and Galectin-9 to suppress monocyte and macrophage recruitment, thereby reducing tissue necrosis and preserving liver function. The findings identify sTim-3 as a potential therapeutic target for drug-induced liver injury.

Parkinson’s disease remains one of the most challenging neurodegenerative disorders, with current treatments offering partial and temporary relief. A new experimental study from the University of Guadalajara investigated whether bee venom could serve as an adjunct to standard therapy. Using a mouse model of Parkinson’s disease, the team examined whether combining bee venom with L-DOPA/carbidopa could improve motor and cognitive outcomes. The findings provide encouraging behavioral evidence, supporting further research into this unconventional therapeutic approach.

Occult hepatitis B virus (OBI) infection presents a significant global health challenge, notoriously flying under the radar of standard viral screening while relentlessly driving the pathogenesis of hepatocellular carcinoma (HCC). A critical but poorly understood factor in OBI-related tumorigenesis is the frequent emergence of mutations in the HBV pre-S genomic region. While these mutations are known to correlate with advanced liver disease, the precise molecular mechanisms by which they hijack host cellular machinery to fuel unregulated tumor growth have remained largely elusive.
