CACNA1C Gene Regulates Behavioral Strategies in Operant Rule Learning

The ability to learn, to adapt one’s own behavior in order to optimize positive and avoid negative feedback, is central to all living beings. Animals like humans are constantly seeking to infer the (causal) structure of their environment and to predict the outcomes of their actions [1,2], sometimes to a degree that “superstitial beliefs” about environmental contingencies may form [3]. However, since the environment is only partially observable, with an often infinite or exponentially exploding space of possibilities, inferring the optimal course of actions is, in general, a computationally intractable problem.

Climate Change

Climate change is a long-term significant change in the weather patters of a geographical area, or in the case, the world’s oceans. Climate change can be natural or caused by changes people have made to the land or atmosphere. It has become perhaps the most complicated issue facing world leaders.

Petersburg’s Resilience to a Tsunami

Tsunamis have a history in Southeast Alaska, whether caused by earthquakes, landslides, or both. These natural disasters have been cited in many cultural tales of Southeast Alaska.

Brain–Computer Interface–Based Communication in the Completely Locked-In State

Communication is the process of expressing and sharing feelings, thoughts, and intentions with one another by verbal and various nonverbal means. Communication skills appear automatic but can pose severe challenges to individuals suffering from motor neuron disorders. The most devastating of motor neuron diseases is amyotrophic lateral sclerosis (ALS) [1], which is progressive and renders an individual motionless, severely affecting his or her communication ability [2].

Platelet-Dependent Killing of C. albicans

There are around 150,000-400,000 platelets per microliter of blood in a healthy human being (Williams, n.d.), each which are around two microns in size (“Platelets on the Web,” n.d.). Platelets are blood cells which assist in the clotting of blood vessels, a process also known as hemostasis.

Arsenic Contamination from Water

The results demonstrate that the uncoated, or bare, magnetite nanoparticles were the most effective in the removal of arsenic from the water, when compared to the results of the nanoparticles with the humic acid and oleic acid surfactants.

Bigger Is Fitter? Quantitative Genetic Decomposition of Selection Reveals an Adaptive Evolutionary Decline of Body Mass in a Wild Rodent Population

Given the rapid anthropogenic environmental changes experienced by organisms around the world, there is an increasing need for an ability to understand and predict the evolutionary dynamics of wild populations [1, 2]. Despite good empirical examples of the adaptive evolution of traits with a simple genetic architecture [3–5], the picture is very different for quantitative traits, which in most cases are a function of many genes of small effect [6].

Citrus Juices on Kidney Bean Plants

Modeling the effects of cryopreservation on kidney bean plants to learn which environment will best suit the plant for efficient growth and sustainability.

Automatic Compilation from High-Level Biologically-Oriented Programming Language to Genetic Regulatory Networks

Synthetic biology is an emerging field at the interface of biology, engineering, and physical sciences, which focuses on the systematic design and engineering of biological systems [1]–[3]. This field brings a set of new approaches for tackling biological problems and at the same time addresses real world problems.

Eco-Friendly Method for Developing Plastics

The purpose of the project is to determine the effects of catalysts on the depolymerization of chitin using ionic liquids.
