Bacteria, fungi and plants sometimes produce metal-binding substances that can be harnessed, for example for the extraction of raw materials, for their separation, for cleaning soils or for medical purposes.
Many of the drugs and medicines that we rely on today are natural products taken from microbes like bacteria and fungi. Within these microbes, the drugs are made by tiny natural machines - mega-enzymes known as nonribosomal peptide synthetases (NRPSs). Researchers have gained a better understanding of the structures of NRPSs and the processes by which they work.
Researchers used double-sided tape - basically the same as you might have at home - to assemble a low-cost version of advanced chip devices for simulating the functions of human organs. The technique could dramatically lower cost barriers for labs that test new drugs and analyze how the body reacts to them.
Before scientists develop the bioengineered tissue of tomorrow for treating pulmonary diseases, they need to identify the best methods for growing tissue for artificial trachea and lungs in experiments today.
Scientists have found a way to turn pollen, one of the hardest materials in the plant kingdom, into a soft and flexible material, with the potential to serve as 'building blocks' for the design of new categories of eco-friendly materials.
Researchers have created a new technique that utilizes photolithography and programmable DNA to rapidly 'print' two-dimensional arrays of cells and proteins that mimic a wide variety of cellular environments in the body.
