New Modified Antibodies Enable Fight Against MRSA And Other Bacteria

The human immune system is usually a tireless worker that does its best to keep us protected from pathogen invasion. But even for all of its complexity, there are certain parts of it that fail hard when confronted. Enemy Identification When it comes to combating bacteria wishing to harm us, one of the first actions […]

Plants Use Root Structures To ‘Listen’ And Search For Water

Water is important for life. It is a primary source of structure and function in all life forms, even including viruses that use it as interstitial fluid for containing their viral genome. For organisms that produce their own complex compounds, commonly known as autotrophs, water remains the main source of outside material they need to […]

New Stem Cell Method Allows Development Of Extra-Embryonic Tissues

Stem cells were often thought of as the holy grail of biological discovery after they were uncovered by Ernest McCulloch and James Till in 1963. A method to produce cells that can form into any part of the body, potentially providing new organs and prevent horrible disorders like leukemia. Of course, things didn’t really turn […]

RNA Editing Allows Cephalopods To Alter Genetic Instructions

The central dogma of molecular biology and genetics is pretty straightforward. You take DNA, then you transcribe the desired gene into RNA (usually mRNA) and, once outside of the nucleus, you translate that RNA using ribosomes into amino acids that then form proteins. Those proteins then do the actual function that their original genetic encoding […]

Genetically Engineered Inflammation-Sensing Bacteria Made With Synthetic Biology

Synthetic biology is complicated. When you’re building biological systems from the ground up, how could it not be? But the results are almost always something amazing, a real revolutionary accomplishment that wouldn’t be possible with any other field of science. The only other field that comes close is nanotechnology and mechanical systems are still somewhat […]

Making An Artificial Tree On A Chip For Hydraulic Robotic Power

We’ve discussed the creation of electronic plants recently and the idea of using plants as electrical storage and transferring devices, allowing an electric connection from, say, one end of a garden or field to another. But plants can transfer far more than just electricity. They are already masters at transferring necessary nutrients from the soil […]

Using Genetically Modified Ants To Figure Out Just How Ants Work

Ants are fascinating. As examples of highly social, structured, and often single-minded species, ants easily pique the interest of biologists and even scientists as a whole. Similar to bees, their colony structure exists as highly divergent from the rest of the multicellular life in the world. Most of it, at least. They can be viewed, […]

Creating An Artificial Embryo Using Genetically Modified Stem Cells

Cloning is a difficult process. Even with modern technologies, the best we can do is generate matching organs from a person’s stem cells, but this itself is still tricky to accomplish. Actually cloning a whole organism? We’re nowhere near where we need to be. The Troubles of Cloning The main problem inherent in this process […]

A Tenet Of Evolutionary Biology May Be Completely Wrong

Not every tenet of science is set in stone. That’s often been seen in fields like physics and astronomy over the past few decades, where huge innovations and discoveries have been made. But biology isn’t isolated from these sorts of findings. Today’s topic of discussion is new research that calls one of the tenets of […]
