Viruses are Nature’s delivery vehicles. Millions of years of evolution have molded them into remarkable machines capable of performing a monumental task vital to their survival: the delivery of genetic material into other organisms.
Viruses are shells made up of proteins and sometimes lipids that carry genetic information into cells. The type of genetic material (DNA or RNA), shape, size, and the process of delivery differ between different virus families.
Current state-of-the-art research uses bio-mined viruses as blueprints for the creation of new materials and therapeutics that can benefit humanity. For example, the field of gene therapy harnesses the efficient ability of viruses to infect host cells and turns them into delivery vehicles for the genetic treatment of people suffering from debilitating diseases and disorders.
The US Food and Drug Administration recently approved Luxturna—a gene therapy drug that uses a benign virus for the treatment of hereditary blindness in children. This is the first gene therapy product for a genetic disease approved for clinical use in the US, and has opened the gates for approval of other virus-based therapies for treatment of genetic diseases, including hemophilia, Duchenne muscular dystrophy, and cystic fibrosis. In order to continue advances in such applied areas, more knowledge about how viruses work and how to control their functions is needed.

3D Human Brain Tissue Model Replicates Alzheimer’s Pathology
Summary: Researchers introduced a highly reproducible three-dimensional human brain tissue model capable of replicating complex neurodegenerative processes in Alzheimer’s disease. Developed over nine years using human stem cells, the self-organizing tissue spheroids integrate functional neurons, [...]
A Common Sugar May Loosen Cancer Cells and Help Them Spread
Chemotherapy may kill most ovarian cancer cells, but the few that survive can turn dangerously active. By releasing fructose, they may help nearby tumor cells break free and spread. Researchers at The Wistar Institute [...]
COVID-19 can wake up dormant viruses in the body, large study confirms
Virus reactivations by SARS-CoV-2 could worsen initial symptoms and increase risk of Long Covid. Early in the COVID-19 pandemic, scientists noticed that a SARS-CoV-2 infection can “wake up” other, dormant viruses already present in [...]
Scientists Discover the Brain May Enter a New Biological Phase Between 50 and 75
A single-cell study reveals major changes in immune cells, genome organization, and gene regulation within the aging human hippocampus, offering important insights into brain aging and dementias associated with age. Between roughly ages 50 [...]

Unzipping the Code of Life: Scientists Pinpoint Where DNA First Opens
Researchers mapped where DNA first opens and how a helicase gate may release one strand as genome copying begins. Before a cell can divide, it must open its tightly wound DNA and begin copying the entire [...]
Scientists Tested an 8-Hour Eating Window and Found a Surprising Brain Benefit
Limiting the daily eating window may provide brain benefits beyond those associated with weight loss. Eating within a shorter daily window may provide cognitive benefits beyond those associated with weight loss alone, according to [...]
Focused Ultrasound Opens Blood-Brain Barrier to Treat Brain Cancer
Summary: A new study demonstrates that primary brain tumors (gliomas) are particularly receptive to targeted drug delivery using focused ultrasound (FUS) combined with microbubbles. The team developed a high-resolution MRI protocol to track blood-brain barrier [...]
AI’s promise and practical limits in drug discovery
AI tools are becoming increasingly common in early drug discovery, allowing scientists to analyse data and navigate large volumes of research. However, according to Dr Raminderpal Singh, turning that potential into consistent scientific workflows [...]

Health-related updates reveal financial adjustments by Universal Health Services due to Medicaid reimbursement uncertainties, significant pollution-linked health concerns from French-British oil firm Perenco in Congo, drug trial setbacks, potential restructuring at major medical firms, [...]
Scientists Discover the Brain Protein That Helps Alzheimer’s Spread Through the Brain
Scientists have identified a brain protein that may help Alzheimer’s spread, revealing a potential new target for slowing the disease’s progression. Alzheimer’s disease is closely linked to the accumulation of a toxic form of the protein [...]
How Immune Dysregulation Contributes to Psychiatric Disorders
Introduction Growing evidence suggests that disruptions in immune function may play an important role in the development and progression of psychiatric disorders. However, immune mechanisms probably contribute more strongly in some patients than others, [...]
Electrostatic Discharge Boosts Triboelectric Nanogenerator Current and Enables DC Output
Controlled electrical discharges could enable triboelectric nanogenerators to achieve higher peak currents, extending nano-enabled energy harvesting into chemical processing and self-powered sensing. Paper: Electrostatic discharge as a breakthrough strategy for triboelectric nanogenerators. A new review [...]
Swiss laboratory uses old drugs against rare diseases
Researchers at the University of Geneva are combing through collections of approved drugs to find new therapies for rare diseases – with some success. This approach is gaining traction around the world, while pharmaceutical [...]
Nanozyme Aptasensors Show Promise for Faster Food, Health, and Environmental Testing
By pairing robust artificial enzymes with highly selective aptamers, nanozyme aptasensors could help detect disease biomarkers, pathogens, and contaminants faster, but the review shows that real-world deployment still depends on overcoming matrix interference, biofouling, [...]
