Airbnb Externship Shows 3L Isabel Samayoa How Legal Strategy Drives Business Growth - UC Law San Francisco (Formerly UC Hastings)
An externship at Airbnb provided 3L Isabel Samayoa exposure to areas such as contracts, licensing, risk management, and growth strategy, helping her develop the skills and experience to thrive in her future career as a corporate transactions attorney. 3L student Isabel Samayoa reflects on her work with Airbnb’s in-house legal team through UC Law SF’s Corporate Counsel Externship Program. Supported Airbnb’s legal team on commercial contracts, open-source licensing, external partnerships, product counseling, and legal research. Observed how legal advice aligns with business strategy and risk management. Gained exposure to strategic decision-making while preparing for a career in corporate transactions. Q: What did you do in this corporate externship? A: I supported the Airbnb legal team across several functions, including commercial contracts, open-source licensing matters, strategic external partnerships, legal research, real estate matters, internal AI integration, and product counseling. I also gained exposure to corporate structure counseling, litigation, patent counseling, and the company’s broader business strategy. Q: What did you take away from this experience? A: One of the most valuable parts of this experience was learning how a business actually operates. I had never worked on such a large team in the private sector, so I had little exposure to how companies run internally. I learned how lawyers can provide valuable advice to support business goals, seeing how leadership evaluates risk and develops growth strategies. Understanding those priorities allows me to calibrate my legal advice to clients, balancing the client’s goals against the level of risk they are willing to take. Q: How does this experience support your career goals? A: Exploring the anatomy of a successful company was incredibly valuable because I plan to pursue a career as a corporate transactions lawyer. Being in the room with the teams discussing important decisions allowed me to see firsthand the factors that contribute to that success and how lawyers help guide those decisions. Q: Would you recommend UC Law SF and this externship? Why? A: I would absolutely recommend this opportunity. While the team worked on high-stakes matters at a highly successful company, they still created an environment where I felt welcomed. They trusted me with meaningful work and supported me every step of the way. This helped me build confidence in my analytical abilities. Q: What’s your favorite UC Law SF memory so far? A: Some of my favorite UC Law SF memories, aside from my time at Airbnb, involve mentorship. I have benefited from mentorship and have also had the chance to mentor other law students. Watching the students I mentored go on to mentor others has been particularly rewarding. I think mentorship is integral to the legal profession, and it has been inspiring to see that culture thrive at UC Law SF and continue beyond the classroom. The Evidence of Success series highlights UC Law SF students as they share how the College’s opportunities equip them with the experience, skills, and confidence to excel in the legal profession.

Ruby Ridge Book Explores Roots of American Conspiracy Politics at Vroman’s Tonight
Author Chris Jennings will discuss his critically acclaimed book “End of Days: Ruby Ridge, the Apocalypse, and the Unmaking of America” at Vroman’s Bookstore on Monday, March 30, in a 7 p.m. conversation with journalist and author Jim Newton, a Pasadena resident. The book, published in February by Little, Brown and Company, examines the 1992 Ruby Ridge standoff — in which federal agents surveilled a cabin in Boundary County, Idaho, as part of an operation to arrest white separatist Randy Weaver — and traces a line from that 11-day siege to the conspiratorial politics that now mark American public life. By the time Weaver surrendered, his wife, his son, and a U.S. Marshal were dead. Jennings, a former editorial staffer at The New Yorker and the author of “Paradise Now: The Story of American Utopianism,” argues that the strain of apocalyptic Christianity that gripped the Weaver family can be traced to biblical prophecy readings dating to the 1870s and through the rise of 20th-century fundamentalism, according to the publisher’s description. The events at Ruby Ridge, Jennings contends, acted as an accelerant for this worldview. The New York Times Book Review called the book a thoroughly researched chronicle written with precision, according to a review published in February. Kirkus Reviews described it as a vivid reconstruction of a pivotal moment in the history of right-wing extremism. Newton, who will lead the conversation, spent 25 years at the Los Angeles Times as a reporter, editor, bureau chief, and columnist, including a stint as editor of the editorial pages from 2007 through 2010. He is the author of four books, including biographies of Chief Justice Earl Warren and Gov. Jerry Brown. Newton teaches at UCLA, where he founded Blueprint magazine, and is a columnist for CalMatters. He received the American Political Science Association’s

Scientists Stunned: Colossal Eggs Discovered 3,500 Meters Beneath an Active Volcano
Beneath an active seafloor volcano off Vancouver Island, researchers have documented a congregation of giant eggs at roughly 3,500 meters, a discovery that reframes how life can flourish under extreme conditions. The eggs belong to the Pacific white skate, an elusive deep‑sea species adapted to cold, crushing pressure and perpetual darkness. What seemed an unlikely nursery is actually a geothermally warmed refuge, where subtle heat helps embryos survive a marathon incubation. The finding links volcanic energy to a quiet engine of biodiversity, turning a hostile landscape into an incubator. A living volcano, a hidden nursery The seamount long assumed dormant now exhales mineral‑rich, shimmering plumes, proof of hydrothermal life at depth. Expedition cameras swept across black basalt and pale bacterial mats, revealing vents that pulse with warmth. That warmth, though modest by human standards, alters the physics of development for cold‑adapted embryos. In a realm where metabolism creeps, even a few degrees can mean faster growth and higher survival. The volcano is not only active; it is ecologically formative, drafting a blueprint for a thriving oasis. Giant eggs and a skate built for the abyss The Pacific white skate, Bathyraja spinosissima, is built for the abyss: broad wings, armored spines, and a life history that trades speed for endurance. Females lay outsized, rectangular “mermaid’s purses,” often 46–50 centimeters long, packed with rich yolk to fuel years of growth. In the frigid deep, embryos can require around four years to hatch, a timeline that magnifies every energetic advantage. The scale is striking—large eggs, large adults, and a textbook case of deep‑sea gigantism. The volcano’s gentle heat may literally shave months or years from the wait. Why heat matters at the bottom of the sea Hydrothermal circulation delivers low‑level warmth without the turbulence that would scatter fragile egg‑cases. Slightly elevated temperatures accelerate enzyme kinetics, nudging development along while keeping embryos within a safe range. Mineral‑laden fluids likely shape local microbiomes, which, in turn, can influence biofilms on egg surfaces. The environment acts like a slow, steady incubator, countering the deep sea’s tyrannies of cold and scarcity. For a species with long maturation and few offspring, every incremental boost compounds across generations. An ecosystem sculpted by fire and water Seafloor volcanoes create steep environmental gradients, stitching together hot vents, cool eddies, and mineral gardens into mosaic habitats. Microbes harvest chemical energy, seeding food webs that support crustaceans, fishes, and skates. Cameras documented egg‑cases nestled among rocky ledges, near communities nourished by vent‑driven chemistry. These islands of productivity behave like deep‑sea oases, sustaining life far beyond the vent orifice’s flickering light. The nursery’s success underscores how geological forces engineer biological opportunity. “Finding a cradle of life tucked beneath a breathing volcano reminds us that the planet’s harshest places can be profoundly generous.” What the discovery could change The nursery reframes conservation priorities in regions where volcanism quietly underwrites reproduction. Protecting hydrothermal corridors could safeguard entire lifecycles, not just charismatic adults spotted during occasional surveys. It also sharpens questions about how climate‑driven shifts in ocean circulation might influence vent activity, temperature fields, and embryo survival. With methodical mapping, time‑series cameras, and environmental DNA, scientists can track whether nurseries remain stable or drift with geologic rhythms. Key implications include: Enhanced understanding of deep‑sea reproduction at hydrothermal sites. New conservation targets centered on geothermal nurseries. Comparative studies with other volcanic regions, from the Galápagos to rift zones. Biotechnological insights from organisms adapted to long, cold development. Better models of how seafloor heat shapes regional biodiversity. Methods behind the revelation Remotely operated vehicles threaded through chimney fields, gathering video, temperatures, and mineral signatures. High‑definition imagery captured the distinctive, horned egg cases, their edges dusted with fine volcanic silt. Geochemical profiles mapped how heat and chemicals disperse, outlining the “thermal lanes” where eggs most cluster. Combined, these datasets reveal a nursery organized by geothermal topography, with egg‑cases concentrated in pockets of gentle, sustained warmth. A fragile boon in a changing ocean Deep‑sea environments feel remote, yet they intersect with global pressures: mining proposals, cable routes, and shifting oxygen levels. The nursery’s resilience hinges on stable heat flow, intact substrates, and minimal disturbance from noise or sediment. Safeguarding such places is not just about protecting novelty; it preserves a slow, ancient strategy that lets large, long‑lived animals endure in the coldest reaches of the Pacific. Where geology and biology meet, the planet’s deep time still writes living stories. This volcano‑warmed nursery adds a vital chapter to that story, revealing how subtle thermal gifts can tip the scales toward life in the abyss. With each dive, researchers trace the contours of an unseen world, where fire feeds water, and water—against all odds—feeds the future.

Hingham Schools Eye Business Curriculum Expansion as Class Size Concerns Mount
HINGHAM - March 23, 2026 - The Hingham School Committee moved to modernize its high school offerings Monday night, reviewing a comprehensive plan to expand the “small but mighty” Business Department while simultaneously grappling with data that places Hingham as an outlier in elementary class sizes. Director of Social Studies Andy Hoey presented a two-year program review that highlighted the department’s success in community partnerships but warned that high student demand is testing current staffing limits. Meanwhile, committee Chair Jen Benham presented independent research showing Hingham is the only benchmark district with second-grade classes hitting a 25-student cap, sparking a directive for the Policy Subcommittee to review class-size standards. Editors note: South Shore News is going paid in April, subscribe now to make sure you don’t miss a story. Reach out for group or organizational pricing. Subscribe The Full Story The meeting opened with a look into the future of Hingham High School’s (HHS) curriculum. Andy Hoey, who oversees the Business Department, presented the first formal program review for the department since 2009. [15:09] Hoey characterized the department as a vital elective hub that currently serves between 14% and 27% of the HHS student body in any given year. [31:31] “We are very proud of our business department here at Hingham High School... while we’re very proud of it, we are always striving to make improvements and enhancements.” [15:55] — Andy Hoey, Director of Social Studies A key highlight of the presentation was the announcement of a new AP Business with Personal Finance course launching next year, pending enrollment. [20:08] The review team found that while the program is “well-aligned” to national standards, it remains a high-school-only offering. Hoey outlined an action plan to explore “vertical articulation,” potentially introducing business or financial literacy units at the middle school level to fill a “gap” identified between fifth and eighth grade. [41:48] However, the department faces “smoke and mirrors” regarding student GPA, according to Hoey. Currently, most business courses are “unleveled” and do not count toward a student’s GPA, which survey data suggests may deter some students from enrolling. [28:15] The committee discussed the possibility of offering Honors or College Prep (CP) credit for advanced courses, such as investing or marketing, to better reflect their academic rigor. [38:27] The discussion took a sharp turn toward elementary education during an enrollment update. Superintendent Dr. Katie Roberts noted a net gain of four students mid-year, but it was Jen Benham’s “rabbit hole” data analysis that caught the committee’s attention. [50:35] Benham researched 13 benchmark towns—representing 34 elementary schools—and found that Hingham was the only district with a second-grade section reaching 25 students this year. [51:36] Benham’s findings suggested that while many districts lack formal class-size policies, Hingham’s current cap of 25 for second grade may be too high. “I think if we could at least have 23 at a cap for grade two,” Benham suggested, noting the importance of that grade level for literacy development. [53:09], [54:55] Dr. Roberts cautioned that smaller classes require more staff, which is a significant hurdle following a budget season where nine general education positions were cut across the district. [55:56] The committee also finalized the 2025 Town Report, which was updated to be more “student-centered” and highlight staff early in the document. [11:12] Additionally, a series of food service policies were approved to align with Massachusetts’ universal free school meal mandate, including new protocols for meal modifications due to allergies or religious needs. [59:23] Share Why It Matters The meeting underscored a tension between Hingham’s desire to offer elite, specialized programming and the foundational pressure of class sizes. The expansion of the Business Department—including potential Microsoft certifications and AP courses—aims to prepare students for a “real world” where credit scores and financial literacy are paramount. [46:20] However, the revelation that Hingham’s second-grade classes are larger than those in all neighboring benchmark towns suggests a potential strain on early education that could impact long-term student performance if not addressed by the Policy Subcommittee. Official Minutes & Data Key Motions & Votes Motion: To approve the Hingham Public Schools 2025 Town Report. [13:16] Vote: Unanimous (7-0) ([01:13:28]) Motion: To approve the Memorandum of Agreement (MOA) for summer counselor work regarding course placement. [57:33] Vote: Unanimous (7-0) ([57:50]) Motion: To approve Policy EFBA (School Food and Nutrition/Meal Modifications). [01:00:32] Vote: Unanimous (7-0) ([01:00:44]) Motion: To approve Policy EFC (Universal Free School Meals). [01:00:54] Vote: Unanimous (7-0) ([01:01:07]) Public Comment No members of the public spoke during the meeting or via the remote link. [01:02:30] What’s Next The Policy Subcommittee will take up the review of elementary class-size caps over the next year to determine if the Grade 2 limit should be lowered from 25 to 23. [52:18] The Business Department will monitor enrollment for the new AP Business course and continue exploring dual-enrollment partnerships with Quincy College.

Glyphosate: A story of science, risk, and nuance
In the summer of 2014, a California groundskeeper named Dewayne Johnson started noticing patches of raw, weeping skin spreading across his body. He had spent years applying Roundup, Monsanto’s glyphosate-based herbicide, for a school district, sometimes drenched in it when equipment malfunctioned. By 2014, he had a diagnosis: non-Hodgkin’s lymphoma. In 2018, a jury awarded him $289 million in damages, later reduced on appeal. Tens of thousands of lawsuits followed. The story hasn’t quieted down. It’s all over the internet, swinging between “this will kill you, buy organic” and “relax, you’re fear-mongering.” Some of that recent chatter stems from an Executive Order protecting glyphosate and its production, which set off intense infighting within the MAHA movement. Some of it reflects a deeper truth: Americans genuinely care about harmful chemicals in their environment (see poll below). And the conversation isn’t going anywhere, with a Supreme Court case involving Monsanto set for this April. Glyphosate (the active ingredient in Roundup) is one of the most widely used herbicides in the world. But does glyphosate cause cancer? And how much exposure is actually risky? With so much mistrust in institutions and corporations (and some genuine conflicts of interest), making sense of the actual scientific evidence is genuinely hard. Here is a translation of what the scientific evidence actually says. Does glyphosate cause harm? Glyphosate is an herbicide that kills most plants it contacts rather than targeting specific species. It works by blocking an enzyme pathway (EPSPS) that plants and many microorganisms need to produce essential amino acids. Without those amino acids, the plant can’t grow and dies. Glyphosate was first developed by Monsanto in the 1970s and became ubiquitous after the company introduced “Roundup Ready” crops in the 1990s. In 2024, Bayer removed glyphosate from residential Roundup-branded products due to litigation pressure. But today it is still the most widely used herbicide in the world. Farmers also discovered they could spray it directly on crops like oats, lentils, beans, and peas just before harvest to dry them out faster and make harvesting easier. Because of its widespread use, it’s obviously really important to understand if it’s harmful to humans. The key principle: The dose makes the poison The most important concept in toxicology is that “the dose makes the poison.” Sixteenth-century physician Paracelsus articulated what remains the foundational principle of toxicology: sola dosis facit venenum. Water will kill you if you drink enough of it. Aspirin saves lives at 81 milligrams and causes internal bleeding at higher chronic doses. So, at what dose is glyphosate poisonous? The LD50 in rats (the dose that kills half the test animals) is around 5,600 mg/kg body weight. Table salt is roughly 3,000 mg/kg. By that classic measure, glyphosate is less acutely toxic than salt. But some people are exposed to a lot of glyphosate through their work. And among the general public, there are many questions about low-dose, cumulative exposure from multiple sources over long periods. Does glyphosate cause health problems? Cancer Correlation maps are striking, with one analysis finding that 60% of counties that spray the most glyphosate have non-Hodgkin’s lymphoma rates above the national average. But correlation alone doesn’t establish cause, which is why animal and human studies matter. In animals: Rat studies are typically what most fear is rooted in, but most people don’t know the study details on the dosage given to rats. A pooled analysis of the 13 most rigorous rat studies found evidence that very high doses, around 55,000 times greater than typical food residue exposure, can cause certain cancers. In humans: One of the strongest studies followed 55,000 herbicide users over 20 years and found no overall increased cancer risk. There was one signal: among those with the highest use, rates of acute myeloid leukemia (AML) appeared elevated. A broader meta-analysis of 18 human studies also found no overall cancer risk, though a separate meta-analysis focused specifically on non-Hodgkin lymphoma found that people with high cumulative glyphosate exposure faced a 41% higher relative risk compared to those with low or no exposure. These human studies are observational studies (randomized controlled trials would be unethical), and meta-analyses are only as reliable as the studies they pool. But the story seems consistent: at very high exposure levels, there may be some cancer risk. But that’s about as far as the science currently takes us. Emerging research: gut and reproductive health Gut: Because glyphosate targets a pathway that exists in some gut bacteria, scientists have questioned whether it could affect the microbiome. In mice, a 2023 University of Iowa study found that glyphosate altered gut bacterial composition and raised markers of intestinal inflammation. A 2024 systematic review found similar patterns: disrupted gut bacteria and problems with the mucus layer that protects the intestinal wall in mice. Whether this translates to humans is an open question. The human gut is highly variable and resistant, and we don't yet have strong studies confirming the same effects in people. Reproductive health: Animal studies have found that glyphosate-based herbicides can interfere with reproductive hormones, including disrupting egg cell development in mice and reducing the number of eggs available in sheep’s ovaries. However, the doses used in these experiments were high, so it’s not yet clear whether the same effects would occur in humans. On the human side, a 2021 pilot study led by Mount Sinai researchers tested urine samples from pregnant women across the U.S. and found glyphosate in 95% of them. The study also found a possible connection between higher glyphosate exposure during pregnancy and a subtle physical difference measured in female newborns. That said, some connections weren’t statistically reliable and this was a small study. The researchers themselves said more and larger studies are needed before drawing firm conclusions. What do regulators say about glyphosate safety? In 2015, the International Agency for Research on Cancer (IARC), part of the World Health Organization, classified glyphosate as "probably carcinogenic to humans" (Group 2A). The classification is worth taking seriously. But, there’s an important distinction: IARC classifies hazard, meaning the potential to cause harm under some conditions. It does not assess risk, which accounts for actual exposure levels and the real-world probability of harm. The U.S. EPA, the European Food Safety Authority, Health Canada, and regulatory agencies in Australia and Japan have all concluded that glyphosate is “unlikely to be carcinogenic to humans” at realistic exposure levels. They’re asking a different question: given how much of this people actually encounter, what is the probability of harm? Your actual exposure is what determines your actual risk. What does glyphosate mean for your daily life? At the grocery store: Food residues are small. The EPA’s acceptable daily intake is 1.75 mg/kg of body weight per day. To hit that threshold from oatmeal alone, a 150-pound adult would need to eat roughly 50 pounds of oats every day. But this calculation addresses only one pathway (food), and we don’t yet have robust tools to measure people’s actual total exposure. If reducing exposure matters to you, organic certification prohibits synthetic herbicides, and organic oat products generally test at lower or undetectable levels. Either way, a diet rich in whole grains, conventional or organic, is far better for your health than one that omits them out of fear of residues. On the farm: Occupational exposure is orders of magnitude higher than consumer exposure. Farmers and farm workers who mix, load, and apply glyphosate-based herbicides, especially without protective equipment, face meaningfully different risk profiles. Proper PPE isn’t optional. Integrated weed management strategies that rotate chemical modes of action are also worth taking seriously, both for health and for long-term effectiveness. If you live near a farm: Spray drift is real. Concentrations near field edges can spike during and after application, particularly on windy days. This is an area where I think public health could really step up and empower rural communities with buffer zones, rather than placing the onus on individuals. But for now, knowing your local agricultural calendar and keeping windows closed during application are the first steps. Bottom line Dewayne Johnson was exposed to glyphosate at levels most people will never encounter, and a jury decided he deserved compensation. That outcome is not evidence that the oatmeal in your pantry is dangerous. But it is a reminder that the dose, the context, and the person doing the exposing all matter enormously. Glyphosate is a chemical tool with benefits, trade-offs, and genuine open scientific questions. Learning to hold that complexity without collapsing into panic or dismissal is, honestly, one of the most useful and hardest things to do in navigating modern health science.
