New nanoparticle separation method boosts biotech and cancer research

-
Image
  In nanoscale particle research, precise control and separation have long been a bottleneck in biotechnology . Researchers at the University of Oulu have now developed a new method that improves particle separation and purification. The promising technique could be applied, for example, in cancer research. Separating nanosized particles remains a persistent challenge in biotechnology. Once particle size drops below a few hundred nanometres, their behaviour becomes dominated by diffusion – the random walk of particles. This weakens the forces used to guide them, causing separation accuracy to collapse. A microfluidics research group led by Professor Caglar Elbuken at the University of Oulu has developed a new solution to the problem. The method significantly improves the separation and purification of both small synthetic particles and nanoscale vesicles secreted by living cells. Particle separation is crucial because many biological processes occur precisely at the nanoscale. Extr...

Nervous system actively promotes pre-cancerous pancreatic lesions

-
Image
  Pancreatic cancer has a lot of nerve. Notoriously tricky to detect, the disease also often resists traditional therapy . So, researchers are urgently looking for new ways to disrupt tumor formation. Though scientists know that the nervous system can help cancer spread, its role in the disease's earliest stages remains unclear. "One phenomenon that is known is called perineural invasion," says Jeremy Nigri, a postdoc in Professor David Tuveson's lab at Cold Spring Harbor Laboratory (CSHL). "This means cancer cells will migrate within the nerve and use the nerve as a way to metastasize." Now, Nigri and his colleagues at CSHL have discovered that the nervous system plays an active part in pancreatic cancer development, even before tumors form. Using 3D imaging, they found that tumor-promoting fibroblasts called myCAFs send out signals to attract nerve fibers. The myCAFs and nerve cells then work together within pancreatic lesions to create a favorable environ...

Senescent neutrophils promote tumor survival across cancer types

-
Image
  Renowned as first responders to threatening infections , neutrophils also happen to feature prominently in the microenvironment of tumors, where they and other immune cells play opposing and frequently mutable roles in promoting-or resisting-cancer progression. Though they've been linked to the growth of multiple cancers, including those of the lung and breast, neutrophils can assume multiple functional states, only some of which have such an effect. Identifying those states has, for technical reasons, proved to be quite a challenge. Now researchers led by Ludwig Lausanne's Mikaël Pittet have discovered a gene expression program executed by tumor-associated neutrophils (TANs) and a corresponding biomarker that uniformly support cancer cell survival and tumor progression across human and murine tumors. The findings, detailed in the current issue of Cancer Cell , identify TANs characterized by this conserved genetic program as a central variable of the tumor microenvironment (T...

Water pressure mechanism enables fast amoeboid cancer cell movement

-
Image
  Cancer is one of the leading causes of death worldwide, marked by the uncontrolled growth of abnormal cells. What makes it more dangerous is the ability of cancer cells to move quickly through the body, allowing them to invade surrounding tissues. While this behavior is well known, the mechanism behind this rapid spread remains unclear. Researchers from Kyushu University set out to fill this gap and unveiled a new physical process that helps cancer cells move rapidly throughout the body. This study was led by Professor Junichi Ikenouchi from Kyushu University's Faculty of Medical Sciences, along with his colleagues at Kyushu University, in collaboration with Yokohama City University. The findings of this study, published in The EMBO Journal on February 3, 2026, reveal how water pressure generated inside cells aids in cancer cell migration. Healthy cells typically move by attaching to surfaces, which allows them to pull themselves forward. While existing therapies can target this...

New catalyst turns carbon dioxide into clean fuel source

-
Image
  A new study from scientists at Yale University and the University of Missouri shows that catalysts made with manganese can efficiently convert carbon dioxide into formate. Manganese is widely available and low cost, making it an attractive alternative to expensive metals. Formate is considered a promising material for storing hydrogen, which could help power the next generation of fuel cells. Hydrogen fuel cells work by turning chemical energy from hydrogen into electricity, similar to how a battery operates. Although the technology holds promise for clean energy, large-scale adoption has been limited by the difficulty and cost of producing and storing hydrogen efficiently. "Carbon dioxide utilization is a priority right now, as we look for renewable chemical feedstocks to replace feedstocks derived from fossil fuel," said Hazari, the John Randolph Huffman Professor of Chemistry, and chair of chemistry, in Yale's Faculty of Arts and Sciences (FAS). Formic acid, the prot...

Researchers identify key factor to help improve treatment for glioblastoma

-
Image
  A groundbreaking study from Brown University Health researchers has identified a crucial factor that may help improve treatment for glioblastoma , one of the most aggressive and common forms of adult brain cancer. The findings, published November 10 in Cell Reports, reveal how differences among cells within a single tumor influence the cancer's response to chemotherapy, and introduce a promising new therapy designed to tip the odds in the patients' favor. Glioblastoma is notoriously difficult to treat. One of the key reasons is that no two cells within the tumor behave exactly alike. Even inside one tumor, some cells may respond to treatment while others resist it, allowing the cancer to persist and grow. For decades, scientists have known that tumors are composed of diverse cells, but the biological forces driving these differences, and their impact on treatment, have remained elusive. Chen's team discovered that a small molecule called miR-181d acts like a master switch...

Phages use small RNA to hijack bacterial cells and boost replication

-
Image
  As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are looking to bacteriophages, viruses that infect bacteria, as an alternative. A new study shows how these phages use a tiny RNA molecule, called PreS, to hijack bacterial cells and boost their own replication. By acting as a hidden genetic "switch" that rewires key bacterial genes, PreS helps the virus copy its DNA more efficiently, offering important insights that could guide the design of smarter phage-based therapies. A new study from the Hebrew University of Jerusalem reveals how viruses that infect bacteria, called bacteriophages or "phages," use a tiny piece of genetic material to hijack bacterial cells and make more copies of themselves. The research shows that a very small RNA molecule, called PreS, acts like a hidden "switch" inside the bacterial cell. By flipping this switch, the virus can change how the bacterial cell works...
