Family living sets the stage for cooperative breeding and ecological resilience in birds

Cooperative breeding is an extreme form of cooperation that occurs when individuals help raise conspecific offspring that are not their own, often while temporarily foregoing their own reproduction. This common form of cooperation has intrigued evolutionary biologists since Darwin and is thought to have evolved multiple times in a range of lineages, including insects, fish, birds, and mammals, usually as a product of kin selection,

Lab-On-A-Chip Device for Disease Diagnostics

RNA-based viruses and bacteria have been sources of large-scale epidemics and pandemics, most notably Ebola, SARS, influenza, hepatitis C, HIV, and the Zika Virus. Normal detection of these biological agents requires multiple lab processes. This project aims to develop a fully integrated lab-on-a-chip device to accomplish this.

Expanding the Neuron’s Calcium Signaling Repertoire: Intracellular Calcium Release via Voltage-Induced PLC and IP3R Activation

Neuronal calcium plays a dual role as a charge carrier and as an intracellular messenger. Calcium signals regulate various developmental processes, such as migration in the central nervous system (CNS), growth-cone behavior, dendritic development, and synaptogenesis, but calcium is also involved in apoptosis, and it regulates neurotransmitter release and membrane excitability.

The Effects of Sea Ice Loss On Harp Seals

This paper explores how the declining rate of sea ice affects the harp seal. Prior to researching, harp seal population was anticipated to diminish due to habitat loss from warming ocean temperatures. It will start by discussing the sea ice projections for the next 50 years and how much it is predicted to decrease.

Phage Encoded H-NS: A Potential Achilles Heel in the Bacterial Defence System

Phage, viruses that infect bacteria and archaea, play a fundamental role in the environment through predation and lateral gene transfer. Uncultured environmental phage have been most extensively studied in marine ecosystems where they have been demonstrated to affect oceanic biogeochemistry.
