Coastal Santa Barbara is considered one of the most idyllic locations on the North American West Coast, but its beauty is frequently disrupted by fast-spreading, wind-driven wildfires. The east-west oriented Santa Ynez Mountains (SYM), rising abruptly over 1,000 meters from the coastal plain, create a distinct climatic environment by separating the cool, stable air over the Pacific from the much drier atmosphere of the Santa Ynez Valley. This topography leads to unique regional wind patterns, including the Sundowner winds, which occur along the southern slopes of the SYM. Leila Carvalho, Professor of Geography and a researcher at the Earth Research Institute at UC Santa Barbara, studies regional and large-scale climate variability and change, including monsoon dynamics, tropical-extratropical interactions, extreme precipitation and temperature events, mountain weather and climate, and regional modeling.

UCLA's Avishek Adhikari, PhD, presents new research on the role of GABAergic neurons in the brain's periaqueductal gray (PAG) region. Previously studied for their involvement in fear and defensive behaviors, these neurons were found to promote food-seeking behavior when activated—even in fully fed mice. Using calcium imaging and optogenetics, Adhikari's team discovered that these neurons are active during food approach but suppressed during eating. The effect is stronger for high-value foods like chocolate or crickets and depends on the mouse's prior experience with that food. A key finding is that these neurons influence behavior through a specific projection to the zona incerta, a subthalamic region. Rather than signaling hunger, this pathway appears to drive food seeking based on reward value, highlighting a new motivational circuit in the brain.

It's time for a new narrative for the ocean, one that reflects current scientific knowledge and acknowledges innovative new partnerships and solutions that center the ocean in our future. In this program, Jane Lubchenco, Professor of Marine Biology at Oregon State University and with expertise in the ocean, climate change, and interactions between the environment and human well-being, talks about the two current dominant narratives for the ocean are anchored in the past. The older one considers the ocean to be so vast, bountiful, and resilient that it is simply too big to fail. This first narrative drives pollution and over-exploitation of resources. A second, more recent narrative is that the ocean is now so depleted, polluted, and disrupted, and the drivers of those outcomes are so powerful and complex, that the ocean is simply too big to fix. A third, new narrative is emerging, based on scientific findings, existing solutions, and innovative partnerships and policies. This new narrative acknowledges that the ocean is central to a safe, clean, healthy, just, and prosperous future. This new narrative tells us that the ocean is neither too big to fail, nor is it too big to fix. But it is too important and too central to our future to ignore.

Humans have long been exposed to three main types of smoke: from early domestic fires, modern wildfires, and more recently, tobacco and fossil fuel pollution. All release tiny particles from partly burned plants, containing harmful chemicals like nitrogen oxides and carcinogens. These particles raise risks for lung cancer, dementia, and even childhood obesity. Studies show that air pollution can disrupt brain chemistry, increase Alzheimer's-related proteins, and activate stress-related genes (NFkB, Nrf2). A new drug (GSM-15606) shows promise in reducing brain damage from pollution in mice. People with the ApoE4 gene may be more vulnerable, while the ApoE3 gene, possibly evolved 200,000 years ago, may offer some protection.

Menstruation is the cyclical shedding of the endometrium triggered by falling progesterone levels. Menstruation is a rare trait found in less than 2% of mammals and likely evolved independently at least 4 times. Why do some mammals menstruate while most do not? The leading hypothesis is that menstruation occurs as a nonadaptive consequence of spontaneous decidualization of the endometrium, which evolved to increase biosensoring of embryo quality. While the trait of spontaneous decidualization (and as a byproduct, menstruation) was likely shaped by natural selection, menstruation also disposes women to conditions such as endometriosis, pre-menstrual syndrome, and bleeding disorders, especially in the contemporary context.

CARTA: Cancer is Normal Development Spun Out of Control with Steve Frank

Play Episode Listen Later May 28, 2025 16:47


Cancer is normal development spun out of control. It is the great plasticity and power of development, without the overarching controls that guide normal development toward an integrated adult form. Instead, whenever a newly developed kind of tissue acquires the ability to survive, grow, and resist control, there is nothing to stop it. That may be why normal adult cells are often terminally differentiated into a restricted cellular program. And it may be why wound healing, which releases the restricted cellular program and powerfully plastic tissue remodeling, is so tightly regulated and, when dysregulated, so often associates with cancer. With regard to evolutionary history, humans develop differently from their ape ancestors, and their lifestyle causes them to suffer different kinds of tissue damage. Those differences in development and wound healing likely led to new aspects of cancer disease over human history.

At 120-feet long, and holding 36,000 gallons of water, the Scripps Ocean-Atmosphere Research Simulator (SOARS) is a unique facility at Scripps Institution of Oceanography. SOARS is much more than a wave generator, it allows scientists to replicate ocean conditions, including wind, waves, water chemistry, temperature, and light, in a controlled environment. By simulating ocean environments in a controlled laboratory setting, researchers are able to study ocean-atmosphere interactions, climate change, and more. Scripps Institution of Oceanography Lead Engineer Douglas Alden and Researcher Grant Deane give an inside look on how scientists are able to study how human activities are changing the ocean and atmosphere, and how these changes impact global climate and other areas like human health and marine life protection.

Human beings show a range of emotional attachment, affection, and infatuation often referred to as “love”. Love promotes long-lasting and secure relationships that involve nurturing and support. Biological mechanisms underlying such behavior involve ancient neuropeptides and their receptors in the brain. These systems are also involved in reproduction, ranging from mating and pair-bonding, to giving birth and lactation. They shape the earliest experiences of all mammals and their mothers. The concept of love and how we experience it are affected by culture and its diverse societal norms. This symposium will explore the evolutionary roots of human love, compare human love to corresponding emotions in other animals, consider human conditions that prevent the expression of such feelings, and examine the key role of love and affection for our development and daily lives.  Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Humanities] [Science] [Show ID: 40506]
