Tiny Plastics, Big Impact: How Microplastics Affect Earthworms and Soil Health

Author: Diego Javier, Class of 2026 A concern that is emerging worldwide is plastic contamination in agricultural soils. Farmers frequently use plastic mulching films in order to improve crop yields and control weeds. However, these films can break down into tiny fragments, called microplastics, which are then ingested by soil organisms like earthworms and can affect soil health. In order to better understand these effects, … Continue reading Tiny Plastics, Big Impact: How Microplastics Affect Earthworms and Soil Health

Climate Change and Zoonotic Diseases

Author:  Antonia Truta, Class of 2028 The World Health Organization’s definition of zoonosis is any disease or infection naturally transmissible from animals to humans, or vice versa. Animals are important to understanding disease transmission, with over 60% of emerging infectious diseases having zoonotic origins. Yet, to fully understand the context of zoonotic disease outbreaks, we must look at our interactions with nature in a larger … Continue reading Climate Change and Zoonotic Diseases

Color or Chemistry? How Tiny Isopods Use Multiple Defenses to Outsmart Predators

Author: Diego Javier, Class of 2026 In nature, color is used by animals as a defense mechanism to ward off predators, signifying whether they are poisonous or dangerous to eat. This type of warning coloration is known as aposematism, a strategy seen across many species including monarch butterflies and isopods, tiny crustaceans that hide under damp soil and rocks. This idea was explored by Professor … Continue reading Color or Chemistry? How Tiny Isopods Use Multiple Defenses to Outsmart Predators

The Ethics of Animal Use in Research

Author: Antonia Truta, Class of 2028 Is the use of animals in research for human benefit morally justified? If so, how can experiments maintain ethical integrity while still advancing scientific goals? Professor Marcel Mertz at Hannover Medical School and a diverse range of colleagues, including scientists, philosophers, and legal scholars, explore these questions with a focus on animal models in research. The emerging field of … Continue reading The Ethics of Animal Use in Research

Vasoconstriction and Heat Stress on Cattle

Author: Maegan Diep, Class of 2029 Figure 1. An image of a cow. Fescue toxicosis (FT) is a common condition brought about by endophyte bacterium-infected varieties of tall fescue plants. While beneficial to the plant, it is harmful to the cattle that consume the plant. In consequence, vasoconstriction, or the narrowing of blood vessels, is a common symptom associated with FT, harming their cardiovascular systems. … Continue reading Vasoconstriction and Heat Stress on Cattle

Harnessing Mango’s Antioxidants to Combat Insulin Resistance

Tiffany Ang, Class of 2026 Mangos, which are rich in vitamins A and C, are not only a delicious fruit, but are also known for their antioxidant properties. A study published in 2025 investigated the effects of regular mango intake on inflammation and insulin sensitivity in overweight patients with chronic low-grade inflammation. Chronic low-grade inflammation is linked to insulin resistance and poor glycemic control, which … Continue reading Harnessing Mango’s Antioxidants to Combat Insulin Resistance

Food or Foe: How Food Neophobia Bars Propensity for Insect Consumption

Kaylie Huang, Class of 2027 Creepy crawly insects are not commonly regarded as appetizing and are often avoided at first glance. However, insects are considered a delicacy in many parts of the world. Proteins from animal sources are becoming increasingly limited, causing a shift towards insects as a possible alternative. Insects are rich in nutritional value, including proteins, fats, fiber, vitamins, and minerals, and even … Continue reading Food or Foe: How Food Neophobia Bars Propensity for Insect Consumption

Human Agriculture and the Soiling of Earth’s Water

Jaenai Tercius, Class of 2028 A major form of pollution brought by industrial human activity is water pollution. Agriculture is a major contributor to water pollution due to runoff from nitrogen-based fertilizers, especially in coastal areas. Nitrogen is an essential nutrient for aquatic organisms, but when present in excess, nitrogen can lead to the overgrowth of organic matter and a decrease in oxygen in water, … Continue reading Human Agriculture and the Soiling of Earth’s Water
