We live in a plastic era. Ubiquitously, the substance is found in our household and communities across the globe. Not only we have filled up our land but also oceans with plastic. Worldwide waste management market size is expected to reach $484.9 billion by 2025 from $303.6 billion in 2017.

Bacteria – Geobacter, to be more specific – discovered electricity much before than we did. And the interesting part is – ubiquitous, groundwater and also the under the ocean dwelling bacteria takes-in the organic waste and give-out “electrons”. Yes, a tiny electric current is an end product of their exhaling process.

Dublin based research team has successfully developed a procedure of 3D bioprinting to design new cartilage templates in the shape of missing bones. This bioprinted template will be implanted in the body to regenerate new bones to fix major injuries and bone defects. Traditionally, such injuries and bone defects require some form of bone grafts that are painful and invasive and often have complications of its own.

Researchers at Ecole Polytechnique Federale de Lausanne (EPFL) Lausanne, Switzerland have developed a centimeter long biosensor chip that lays hidden under a patch of human skin and is communicated via smartphone. The chip tracks the concentration of molecules quantity like glucose, cholesterol and other drugs.

There is still no evidence that suggests the exact number of cells present in human body. Although we can interpret them to be somewhere around hundreds of thousands but the figure is much more than that.

It has always been believed that DNA is the storehouse of characteristics that pass-on from one generation to the next. However, there are other materials in a cell as well that can be attributed to passing on the hereditary traits, claimed a set of researchers at University of Edinburgh.

In an attempt to create a ‘body on a chip’, scientists are working towards fabricating minute working organs of human body on a set of inter-related plastic chips. They have already developed fingertip-sized lungs, guts and livers on the chips. For instance, researchers at Harvard University’s Wyss Institute are revamping ‘bone marrow on a chip’ for studying the effect of radiation.

Experts believe that micromachines or nanobots use in the field of medicine can change the way some of the medical conditions are diagnosed and treated. Using these nanobots, medical payload would be sent directly to the specific injury site. Until now the researchers have achieved to test such micromachines in cell samples under laboratory conditions.

Researchers at the Weizmann Institute of Science, Israel have come up with a silicon chip that can mimic a human cell in producing proteins from DNA. The most basic function of cell is to produce proteins after receiving instructions in the form of DNA sequences. Other genes determine production of the quantity of churning out protein by a complex process involving feedback loops.

In order to replicate ecosystem and chemical origin of life, Stanley Miller, under the supervision of Harold Urey, performed the breakthrough Urey-Miller experiment in 1952. The experiment initiated more than 20 major molecules that form the integral part of life. A team of researchers at Stanford believes that they can do one-step better.
