Controversial CRISPR “Gene Drives” Tested in Mice
Researchers from the University of California tested gene-drive technology in mice. This controversial application of CRISPR, capable of altering the genomes of entire species, has been applied to mammals for the first time. Although the developed…
Understanding Neuroblastoma with Fluorescent Zebrafish Genes
Zebrafish have become the animal model of choice for research in many areas. Now, researchers from Rice University trace roots of cancer development using genetically modified zebrafish. These fish produce fluorescent tags in migratory embryonic…
Big Data Analysis Links Herpes Viruses with Alzheimer’s
Researchers from Arizona State University and the Icahn School of Medicine at Mount Sinai Indiana University made a large-scale analysis and used data from three different brain banks. They concluded that human herpes viruses are more abundant…
Why Is a Male Birth Control Pill Not Around Yet?
Men are still limited to only a few forms of birth control. Scientists are making constant progress but the birth control pill or any other hormonal contraceptives for men are still years away from being safe, reversible, and broadly available.…
Understanding the Biological Bases of Political Orientations and Belief Systems
Perhaps one of the most interesting parts of an organism to study is its brain, as it can be thought to be at the core of identity. The brain allows for complex functions such as memory and associations to exist. Evolutionarily, this has allowed…
Bacteria “Harpoon” DNA To Speed Up Their Evolution
Researchers from Indiana University (IU) have made the first direct visual observation of bacteria taking up foreign DNA from its surrounding. It is a key step in their process of rapidly evolving new traits, including troublesome drug resistance.…
Synthetic Tissues That Build Themselves
Researchers from the University of California have programmed synthetic cells to mobilize nearby natural cells into complex structures. At first, individual cells self-organized into multi-layered structures resembling simple organisms or the…
3D-Printed Sugar Structures Could Help Grow Organs
Engineers from the University of Illinois built a 3D printer that produces a delicate network of thin ribbons of hardened sugar alcohol, isomalt. These detailed biological structures are water-soluble, biodegradable glassy structures that could…
Developing Modern Medicines By Simulating The Human Immune System
Rather than relying on serendipity to discover novel therapeutics, today we can work intelligently to identify antibodies that target exactly what we desire. Our immune system has been refined through millions of years of evolution, and our…
