Baby Fever, Meet Reality Check, Victoria R. Reginaldo

Undercurrents: A Journal of Undergraduate Student Composition

Victoria R. Reginaldo is a Biology major from Weymouth, MA; she was born in Brazil and speaks Portuguese. Victoria explains that this essay was meaningful to her because it allowed her to think about an idea she has carried with her since she was young, the desire to have children, and how that dream is shaped and complicated by the realities of today’s society. “As I get older and begin to realize that life isn’t so simple, it made me want to research and write about how society influences the decision to have children,” she shares. Victoria notes that this …

Sultan Qaboos University Journal For Science

Graphene offers tremendous potential for applications in biomedical and pharmaceutical areas, ranging from molecular diagnostics, biosensors, and prosthetics to implants and drug delivery. However, realising the full potential of graphene is blocked by a limited understanding of the nature and detail of its noncovalent interactions with biological molecules in aqueous dispersion, where such applications can be used. Here, we studied the adsorption of amino acids and peptide on graphene in water utilising Nuclear Magnetic Resonance spectroscopy by observing 1H signals of individual biomolecules when exposed to graphene. The peptide-graphene interactions appeared to be driven by the binding affinity of individual …

From Introduction To Biomass Dominance: The Invasive Fish Striped Piggy (Pomadasys Stridens) Reshaping Demersal Assemblages In The Eastern Mediterranean, Mehmet Cengi̇z Deval

Turkish Journal of Zoology

Rapid increases in the abundance and biomass of nonindigenous species have the potential to profoundly reshape demersal fish assemblages in the Eastern Mediterranean Sea, yet quantitative evidence from long-term standardized surveys remains scarce. In the present study, temporal changes in biomass dynamics and community structure were assessed using fishery-independent trawl surveys conducted on the continental shelf of Antalya Bay (GSA 24) during two periods a decade apart (2009–2010 and 2020–2021), with particular focus on the Lessepsian striped piggy Pomadasys stridens. Based on the second survey, in which both daytime and nocturnal sampling were conducted, the biomass index (BI) differed significantly …

Vaccines For Pandemics: Lessons From Covid-19 For H5n1 And Beyond, Alison Mccarthy, Michael S. Sinha

University of Chicago Legal Forum

The COVID-19 pandemic brought unprecedented challenges to vaccine development and distribution. Never before has a vaccine been developed so quickly and distributed so rapidly. But compared to past pandemics and public health crises—like polio or even the more recent H1N1 pandemic—the United States government’s COVID-19 vaccine strategy depended greatly on the private sector.

COVID-19 vaccines were credited with saving millions of lives worldwide, but private companies reaped these rewards, retained their patent rights, and profited from the vast and pressing need for their vaccines. Now, five years later, not every company views its vaccine work as a success. Financial hits …
