Figure 1. Radiative sky cooling panels increases the electric efficiency of cooling systems by passively emitting heat into outer space.

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 may be within reach as described in a study led … Continue reading Electric-less Cooling

Figure 1. Scientists from UCLA controlled expression of genes Drp1 and Atg1 in fruit flies to promote breakdown and removal of damaged mitochondria.

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 the ineffective mitochondria and inability to remove them are major … Continue reading Controlling Mitochondria to Stop the Clocks

Figure 3. Slow wave activity and low quality sleep affect levels of amyloid beta and tau levels respectively which are linked to Alzheimer’s.

Sleep and Its Impact on Alzheimer’s Disease

By Meghan Bialt-DeCelie ’19 A good night’s rest is hard to come by these days, however a study led by Yo-El S. Ju MD from Washington University suggests that it is more important than one may realize. They found that inadequate sleep causes the Alzheimer’s related protein, amyloid beta, to increase. They tested the amyloid beta levels from the cerebral spinal fluid of 22 middle … Continue reading Sleep and Its Impact on Alzheimer’s Disease

Tardigrade and Its Impact on Survivability

By Meghan Bialt-DeCelie ’19 Whether the world ends in asteroids or radiation, the big question is what, if anything, will survive. Researchers lead by Dr. David Sloan from the University of Oxford assessed the resilience of species when against three astrophysical catastrophes (asteroids, supernovas, and gamma-ray bursts) that could sterilize the planet.  These events threaten the survival of species with radiation and by deterioration of … Continue reading Tardigrade and Its Impact on Survivability


By Meghan Bialt-DeCelie ’19   Since the explosion of CRISPR-Cas 9, a gene editing technology, researchers have been further exploring its mechanisms and ways of improving the system. AcrIIA4 is a known anti-CRISPR protein that inhibits the CRISPR-Cas 9 complex, but the mechanism and residues involved were not as explored. Researchers lead by Jiyung Shin, PhD from The University of California Berkley investigated AcrIIA4 to … Continue reading The Anti-CRISPR

Magnetic Nanoparticles for Oil Removal

Meghan Bialt-DeCelie ’19 One of the costliest processes in oil and gas production is safe disposal of produced water. This water contains tiny amounts of oil that are difficult to separate and make water unsafe for the environment. Traditional methods such as gravitational separation of oil are costly and are not reliable for removing the tiny droplets of oil that remain in the water, making … Continue reading Magnetic Nanoparticles for Oil Removal

How Far the Penguins Should March

Meghan Bialt-DeCelie ’19 The effects of Global Climate Change can dramatically alter the environment as well as the organisms which inhabit it. One species that is particularly affected by climate change is the emperor penguin (EP), so much so that researchers from the Wood Hole Oceanographic Institution (WHOI) believe they should be protected under the Endangered Species Act. The random and unpredictable nature of climate … Continue reading How Far the Penguins Should March

Figure 1. Acoustic analysis of buzzing from foraging bees provides a faster and less invasive method of monitoring bee pollination.

That Buzzing Noise

Meghan Bialt-DeCelie ’19 Bees play a critical role in crop survival. Because of this, farmers and scientists must always stay ahead by following patterns in their behavior to quickly manage and appropriately respond to complications in their population growth. Acoustic analysis of organisms is not a new concept; however, it is not often used on insects. Researchers led by Nicole Miller-Struttmann PhD from Webster University … Continue reading That Buzzing Noise

Figure 1: Using FTIR spectroscopy, researchers showed the presence of collagen in a 195-million- year-old fossilized rib.

Ancient Collegen found in Early Jurassic Fossil

Meghan Bialt-DeCelie – ’19 The hints left in the form of fossils provide better understanding of evolution and natural preservation of biological material. The organic material, like proteins, would often be lost and decomposed, hence discovering soft tissue in a fossil is an intriguing find. Researchers led by Dr. Yao-Chang Lee were able to find preserved protein in a 195-million-year-old rib of a sauropodomorph dinosaur … Continue reading Ancient Collegen found in Early Jurassic Fossil

Caption: A mathematical model predicts sleep patterns impacted by artificial light and socially established schedules.

Model Predicts Sleep Patterns

Meghan Bialt-DeCelie – ’19 Rapid modernization has had an impact on the hours that humans are active, disrupting natural and established rhythms. A team led by Anne Skeldon, PhD, developed a mathematical model that shows the effect of factors like artificial light on the human circadian rhythm and sleeping habits. The mathematical model included three factors involved in sleep regulation: mutual inhibition of wake and … Continue reading Model Predicts Sleep Patterns

Figure 1: mircoCOB 3D Bioprinted tissues can potentially allow 3D printed tissues that are larger and more metabolically active to be sustainably produced.

3D Bioprinted Tissues Improved with Vascular Channels

Meghan Bialt-DeCelie – ’19 One of the biggest problems with engineered tissues is the lack of a vascular system to transport essential nutrients and oxygen. This is the reason why larger and highly metabolic organs are the most difficult to develop with 3D printing. Researchers from the University of California printed prevascularized tissues with microarchitectures using the fast and efficient method of microscale continuous optical … Continue reading 3D Bioprinted Tissues Improved with Vascular Channels

Figure 1: Researchers use chemistry and genetics to investigate what makes the best tasting tomato to improve the tasteless modern commercialized varieties.

Science Behind Tomato Flavor

Meghan Bialt-DeCelie – ’19 Modern commercialized crops have been modified over the years to grow large, plentiful, and resistant to environmental damage. The taste of something like a tomato depends on the sugars, acids, and volatile compounds that are detected by one’s receptors for taste and smell. Researchers sequenced the tomato’s genome and investigated nearly 400 accessions among commercialized, heirloom and wild tomatoes to see … Continue reading Science Behind Tomato Flavor
