    MoS2 quantum dots synthesized with the new approach can potentially generate cancer-killing properties. NUS Engineers have developed a cost-effective and scalable strategy for designing tiny semiconductor particles known as transition metal dichalcogenide quantum dots (TMD QDs) which can potentially generate cancer-killing properties. The team is also looking to optimise TMD QDs for applications such as the next generation TV and electronic device screens, advanced electronics components and even solar cells.

    In surprising reversal, scientists find a Cellular Process that Stops Cancer before it starts

    Left: The 23 pairs of chromosomes of cells in which autophagy is functioning look normal and healthy with no structural or numerical aberrations (each color represents a unique chromosome pair). Right: the chromosomes of cells in which autophagy is not functioning bypass crisis, showing both structural and numerical aberrations, with segments added to, deleted from, and/or swapped between chromosomes–a hallmark of cancer.

    Cellular recycling process, thought to fuel cancer’s growth, can actually prevent it. Scientists studying the relationship of telomeres to cancer made a surprising discovery: a cellular recycling process called autophagy – generally thought of as a survival mechanism – actually promotes the death of cells, thereby preventing cancer initiation.

    Technology offers powerful new genetic tools for human disease research in rodents. Using active genetics technology, biologists have developed the world’s first CRISPR/Cas9-based approach to control genetic inheritance in a mammal. The achievement in mice lays the groundwork for further advances based on this technology, including biomedical research on human disease. Future animal models may be possible of complex human genetic diseases, like arthritis and cancer, which are not currently possible.

    Scientists around the world have been using CRISPR/Cas9 in a variety of plant and animal species to edit genetic information...

    New 3D Nanoprinting strategy opens door to revolution in Medicine, Robotics

    Engineers at the University of Maryland (UMD) have created the first 3D-printed fluid circuit element so tiny that 10 could rest on the width of a human hair. The diode ensures fluids move in only a single direction — a critical feature for products like implantable devices that release therapies directly into the body.
