Precise and coordinated motor movement, such as prehension, is an essential skill for completing everyday tasks. The aim of this study is to quantify the relationship between stereopsis (the ability to see depth) and skilled prehension (the ability to precisely grasp an object). We present objects in a frontal view that minimizes other cues to their shape and ask participants to reach and pick up the objects while recording their hand movements. Because grasping an object relies on 3-dimensional object properties and relative disparity, we predict that individuals with anomalous […]

Gregor Mendels law of equal segregation states that the two copies of each chromosome are transmitted with equal probability to the offspring. However, there are also genes, termed meiotic drivers, that manipulate the genome to be transmitted at greater than 50% frequency. Meiotic drivers have been identified across taxa (including insects, plants, fungi, and mammals), and have profound genomic, evolutionary, and ecological consequences. Moreover, the development of synthetic drive systems is the focus of multiple research groups as a means to control pest and disease vectors, since the >50% transmission […]

Prostate cancer (PCa) is the most common noncutaneous cancer in men and presents with a heterogeneous disease course ranging from indolent to rapidly progressive, fatal disease. Imaging techniques such as magnetic resonance (MRI) and positron emission tomography (PET) imaging are important for differentiating between these phenotypes and selecting appropriate patients for treatments. Although low zinc concentration in malignant prostate tissue has been identified as a biomarker for the presence of and aggressiveness of PCa, there is no method for imaging zinc biodistribution in routine clinical use. One solution is hyperpolarized […]

Plant communities respond to disturbances in many ways; with the increase in disturbance events in California such as fires and droughts, these community responses have increasingly led to unexpected shifts in dominant plant species that negatively affect their ecosystems through each species ecosystem services. In a drought and fire prone place such as Tejon Ranch in Californias central valley, it is vital for the lands managers to understand every plants response to disturbances. My project focuses on a native Californian shrub that, though common on the ranch, has not yet […]

Direction-selective ganglion cells (DSGCs) are characterized from other retinal ganglion cells because they generate a higher rate of action potentials when a moving light stimulus passes over the cell in its preferred direction than when the stimulus moves in the opposite or null direction. Four subtypes of DSGCs have been elucidated, each of which prefer one of the four cardinal directions of visual motion: dorsal, ventral, temporal, and nasal. Although asymmetric synaptic circuitry is a common property of these DSGCs in the mouse retina, asymmetric dendritic morphology is not. However, […]

The internet essentially functions like a mailing system, with data packets sent across a network of devices. These devices act like the post offices and shipping warehouses from our regular mailing system. Until recently, modifying the way things ran for each device worked in a similar fashion to training a new worker. In our case, it took years for manufacturers to develop new hardware that did what the network managers wanted. This is where P4 comes in; it is now feasible to change the functionality of forwarding devices by directly […]

One of the fastest heart rates in the world belongs to one of the smallest mammals, the Etruscan Shrew. Only weighing around 1.8 grams, this animal has a heart rate of 1511 beats per minute (in comparison, human heart rates are around 80 beats per minute). In contrast, the blue whale has a heart rate of about 8 bpm. This phenomenon of heart rate scaling can consistently be found throughout the animal kingdom, with smaller organisms possessing a higher heart rate compared to that of larger animals, though little research […]

Some of the biggest technological hurdles come from the existence of electrical resistance in everyday materials, causing a waste of energy. High-temperature superconductivity is a great solution to this problem. High-temperature superconductors can conduct electricity without dissipating any energy and possess many special magnetic properties, making them useful for long distance power transmission, power storage, transportation, and magnetic medical imaging. However, the currently best high-temperature superconductors still require cryogenic temperatures to be superconducting, making them cost inefficient. Explaining the cause for their behavior has perplexed scientists for many decades, and […]

Lymphocytes are a type of white blood cell that are essential to the function of vertebrate immune systems. Lymphocytes include Natural killer (NK) cells, an important component of the innate immune system. NK cells function through families of stimulatory and inhibitory receptors, providing early response to viral infections and tumor development. In mice, Ly49 C-type lectin receptors make up the largest family of inhibitory receptors expressed on NK cells. NK cells require Ly49 receptor activity in order to discriminate between healthy host cells and infected or abnormal cells and respond […]

Chemotherapy is one of the most widely known treatments for cancer, both for its effectiveness yet fatal side effects. Doxorubicin, a common type of chemotherapy drug, has the ability to kill malignant tumor cells, but is limited by the harmful interactions excess molecules cause towards human tissue. Various resins and activated carbons are being tested for drug capturing mechanisms, as many drug molecules are shown to have high binding capacities towards them. Doxorubicin, however, is more complex due to its ionic nature, and requires the use of ion exchange and […]
