mRNA vaccines – a new era in vaccinology

https://www.nature.com/articles/nrd.2017.243 SUMMARY: Traditional ways of making vaccines include using antigens and weakened or dead pathogens. While these methods have worked for us in the past, their application is limited. They don’t work against cancers and tumors and they can be expensive to produce. Using mRNA vaccines is a new and versatile way to create vaccines.… Continue reading mRNA vaccines – a new era in vaccinology

The making of natural iron sulfide nanoparticles in a hot vent snail

https://www.pnas.org/content/116/41/20376 SUMMARY: The scaly-foot snail also known as Chrysomallon squamiferum is unique in that it makes iron sulfide nanoparticles. Chemically, most creatures who are only able to make minerals (biomineralization) using oxygen. The scaly-foot snail is able to do this in the absence of oxygen, a method that scientists are keen on understanding as it… Continue reading The making of natural iron sulfide nanoparticles in a hot vent snail

Do Full Moons Cause Behavioral Changes?

Exploring the Potential Psychiatric Implications of Astronomical Phenomena SUMMARY: This study looked at the effect of the full moon and other astronomical phenomena on behavior. Researchers recorded the number of incidences (restraints, seclusions, and code green emergencies) that occurred in a psychiatric hospital in Buffalo, NY for 5 years. The results showed no correlation between… Continue reading Do Full Moons Cause Behavioral Changes?

Donkey’s Milk in the Management of Children with Cow’s Milk protein allergy

Donkey’s Milk in the Management of Children with Cow’s Milk protein allergy: nutritional and hygienic aspects SUMMARY: Doctors and scientists have been looking for a good cow-milk (CM) substitute for the 4% of kids who have severe CM allergies. Unfortunately, goat and sheep milk often contain proteins that are similar to those found in CM… Continue reading Donkey’s Milk in the Management of Children with Cow’s Milk protein allergy

Toxic wavelength of blue light changes as insects grow

Toxic wavelength of blue light changes as insects grow SUMMARY: Different wavelengths of light are toxic to insects. In this study, scientists looked at the different effects of blue light on fruit flies (Drosophila). They found that each developmental stage was more susceptible to different wavelengths. There were also differences between males and females. For… Continue reading Toxic wavelength of blue light changes as insects grow

Anhydrobiosis without trehalose in bdelloid rotifers

Anhydrobiosis without trehalose in bdelloid rotifers SUMMARY: There are many types of organisms that can dry out, rehydrate, and then go about their lives with no problems. Many of the larger ones use trehalose or sucrose as an antifreeze. Bdelloid rotifers (tiny microscopic animals) do not. This study looked at the carbohydrate content in desiccated… Continue reading Anhydrobiosis without trehalose in bdelloid rotifers
