A future without transplant waitlists? Tissue engineering blends biology and engineering to build living, functional human tissue.

This architecture is essential for shielding neurons from toxins, pathogens, and fluctuations in the bloodstream, but it also creates a devastating bottleneck for modern medicine. More than 98% of small-molecule drugs and nearly all large biological therapeutics fail to cross the BBB in meaningful amounts, leaving many promising treatments for neurodegenerative disorders, brain tumors, and inflammatory diseases stranded in the circulation.

Cells constantly sense signals from their environment and convert them into internal actions through biochemical signalling pathways.

Smart nanoparticles are an exciting step forward in modern medicine especially nanomedicine. They help doctors be more precise in cancer treatment.

In Sci-fi visions of distant futures, some imagine sprawling intergalactic civilizations. Scaffolds built around stars harvesting their energy. Fusion reactors, cyborgs, superintelligent implants. But the future of artificial bones, though perhaps more mundane, could be a life saving science.

Discover how the SNAP29 gene guides cellular traffic, and how its mutation leads to CEDNIK syndrome, affecting brain, nerves, and skin.

Tiny but powerful, basement membranes support cells, regulate barriers, and drive disease when disrupted—key players in health, aging, and cancer.

Small fruit fly is an excellent model organism used by scientists to study various aspect of human health and diseases such as development, regeneration, wound healing, cancer and stem cell research

Explore the multi-organ cellular mapping of GLP-1 receptor agonists. Discover how GLP-1RAs act as a systemic shield across T2DM, obesity, PMOS, MASH and so on.

The Internet has transformed the world, connecting people, information, and resources in unprecedented ways, even beyond physical boundaries. What began as a small research project has now grown into a global system that supports billions of devices and enables nearly every aspect of modern life. In this article, we will explore the major discoveries and milestones that contributed to the development of the Internet.

The human ear is often described as one of the most sophisticated sensory systems in biology. Within a structure no larger than a seashell, the auditory system can detect frequencies ranging from the faint rumble of distant thunder to the subtle harmonic texture of a violin string

Bacterial lysates and postbiotics can train your immune system to prevent respiratory infections. Here is why they matter in the era of antibiotic resistance.

Wound healing is a complex and dynamic biological process that occurs through four overlapping phases: hemostasis, inflammation, proliferation, and maturation. To repair tissue damage, the body works intensively, thereby significantly increasing cellular metabolic demands.

Environmental pollution in densely populated regions remains a persistent challenge, particularly where cultural, religious, and social practices intersect with fragile ecosystems. While industrial emissions and vehicular pollution have received substantial scholarly attention, the environmental impact of everyday ritual and community practices

Animal models have traditionally served as the cornerstone of drug safety evaluation; however, major translational challenges persist due to interspecies differences in physiology, metabolism, and genetic regulation. Many compounds demonstrating favorable toxicity profiles in animals later fail during human trials or are withdrawn post-marketing due to unforeseen adverse effects, especially hepatotoxicity and cardiotoxicity (Lee et al., 2025).

These innovative testes, derived from meticulously cultured mouse cells, closely mimic the structure of natural testes, featuring the complex network of sperm tubes essential for reproduction.

Nanotechnology is having a big impact on pharmaceutical sciences, and drug delivery systems are one area where this is most evident. Compared to conventional medication delivery methods, nanoparticles provide a number of benefits, including increased effectiveness and fewer adverse drug reactions.

Cells can be understood as highly coordinated systems in which DNA functions as a comprehensive but inert blueprint, requiring precise interpretation to become biologically active. Gene expression depends on regulatory proteins that orchestrate transcription across time and space.

Tuberculosis (TB) remains one of the world's deadliest infectious diseases, claiming over a million lives each year. TB is the deadliest infectious disease known today, claiming more lives than COVID-19. TB is caused by the bacterium Mycobacterium tuberculosis. TB spreads through the air when infected people breathe, cough, sneeze,

Many physical and computational systems exhibit a familiar behavior: ordered states gradually decay in the presence of noise. Examples appear across science:
