Safety of Tattoo Pigment

By Meghan Bialt-DeCelie ‘19 The safety of tattoo pigments and its pathways in the body has rarely been investigated. Researchers, led by Dr. Ines Schreiver from the German Federal Institute for Risk Assessment, used X-ray fluorescence (XRF) to explore the biokinetics involved in tattoo pigments in the human skin at the micro and nano scale.…

Long Non-Coding RNA’s Role in Drought Resistance

By Meghan Bialt-DeCelie ’19 With the changing environment due to Global Climate Change, sustaining renewable resources such as crops is more important than ever. The changing climate affects the frequency of droughts and high salinity in fertile lands. These issues motivated researchers to investigate methods of increasing plant resistance to these stresses. Researchers from the…

Controlled Degradation of 3-D Printed Biomaterials

By Meghan Bialt-DeCelie ’19 The explosion of 3-D printing technologies allows custom and precise structures to be made quickly and inexpensively. Researchers led by Thomas Valentin from Brown University utilize stereolithographic 3-D printing to create biocompatible structures that could degrade in response to chemical cues. The technique of stereolithography involves shooting photons at unpolymerized materials…

Electric-less Cooling

By Meghan Bialt-DeCelie ’19 Cooling systems are one of the largest and most inefficient consumers of electricity. The goal of cooling systems is to reduce the condenser temperature to below the ambient temperature. Evaporative cooling systems can achieve this, but they require a great amount of water loss to do so. A new cooling alternative…

Controlling Mitochondria to Stop the Clocks

By Meghan Bialt-DeCelie ’19 The respiratory function of the mitochondrion, the energy producing organelle found in the cell, can decline over time. This is because of how the mitochondrion enlarge and assume a more elongated shape. Typically, that mitochondrion will eventually break down and get removed processes called mitochondrial fission and mitophagy respectively. Accumulation of…
