  • Turning California’s Agricultural Waste Into a Solution to Microplastic Pollution

    Microplastics are everywhere. They show up in drinking water, mountain streams, and even human blood. And while big industrial solutions are slowly rolling out for wastewater treatment plants, there’s basically nothing out there for California’s freshwater lakes and rivers, the sources a lot of communities actually drink from.

    That’s the problem this project is trying to solve.

    Fight waste with waste

    California generates over 1.7 million tons of agricultural waste every year just from nut and grape production. A huge portion of that gets burned, which is something the state is actively trying to stop. At the same time, biochar (the carbon-rich material you get when organic matter is heated without oxygen) has been getting real attention lately as a way to pull microplastics out of water.

    The connection seems obvious. What if the state’s agricultural waste could become its microplastic solution?

    This project puts five locally-sourced feedstocks side by side: almond shells, pistachio shells, walnut shells, grape vine prunings, and rice hulls. The goal is to figure out which one produces the most effective and affordable biochar filter for treating freshwater.

    Why biochar actually works

    Biochar traps microplastics in three main ways. Physically, tiny particles get stuck and tangled in its porous structure. Electrostatically, the charged surface of biochar attracts plastic particles. And hydrophobically, non-polar plastics are drawn out of water toward the biochar surface. Recent research backs this up with removal efficiencies above 90% in lab settings, and a 2024 University of Mississippi study showed 86 to 92 percent removal from real agricultural runoff in column filter tests.

    The science is there. What’s missing is data specific to California.

    What makes this comparison worth doing

    No published study has directly compared nut shell biochars from almond, pistachio, and walnut sources for microplastic removal. Grape vine prunings haven’t been studied for this purpose at all. This project fills a real gap, and it goes a step further by including cost-effectiveness analysis, something most academic studies skip.

    The setup is rigorous: five biochar types plus a sand control, 50g of standardized biochar per column, five trials per type (30 total filtration tests), and microplastic counting under a microscope using vacuum filtration. An ANOVA test will sort out whether the differences between biochars are real or just random variation.

    The cost question matters as much as the science

    Good removal rates in a lab are great, but they mean nothing if the material is too expensive to use at scale. Grape vine prunings can often be sourced for free from Napa, Sonoma, or Lodi wineries. Rice hulls run about $15 to $30 per ton. Almond shells fall in the $25 to $50 range. By tracking biochar yield from each feedstock and calculating cost per 1,000 liters treated, the project aims to identify which material gives the best real-world value, not just the best lab number.

    Why this matters right now

    California already requires microplastic testing in drinking water and is working on new standards. The regulatory pressure is real, but practical solutions for natural freshwater systems are still largely missing. A low-cost biochar filter built from locally available agricultural waste could be exactly the kind of tool that bridges the gap between research and something you can actually deploy in the field.

    This project won’t fix microplastic pollution on its own. But it might point to which feedstock deserves serious investment next.

  • NBA Fantasy 2025: Strategies, Sleepers, and What You Need to Know This Season (As of week 6)

    The NBA fantasy world continues to evolve every year. New stars emerge, rotations shift, and advanced analytics give managers more tools than ever. Whether you’re a seasoned vet chasing another title or a newcomer hoping to avoid last place, this season offers a ton of opportunities to outsmart your league.

    In today’s post, we’re breaking down draft strategy, key sleepers, high-upside breakout picks, and management tips that can help you dominate your NBA fantasy league in 2025.

    1. Draft Strategy: The Blueprint for a Winning Season

    Target Players With Strong Usage + Efficiency

    Fantasy value often comes from the sweet spot: high usage but not at the cost of tanking field-goal percentage or turnovers. Look for players who are focal points of their team’s offense but also score efficiently and contribute across multiple categories.

    Examples:

    • Shai Gilgeous-Alexander – elite scoring, assists, steals, free throws
    • Giannis Antetokounmpo – Great defense, scoring and rebounds.
    • Victor Wembanyama – defensive monster with increasing offensive load

    Don’t Ignore Positional Balance

    A common mistake is stacking too many guards early. Elite big men who produce in blocks, rebounds, and FG% are rare. Having at least one elite frontcourt player is often the difference-maker in roto or category leagues.

    In Points Leagues: Chase Volume

    Efficiency matters far less. High-usage scorers, even with bad shooting nights, still deliver.

    2. Sleepers and Breakout Candidates

    ⭐ Jalen Williams (OKC) – Potential All-Star leap

    He’s trending toward a bigger offensive role and already contributes elite efficiency and steals.

    ⭐ Ausar Thompson (DET) – Defensive stat magnet

    Even with limited shooting, he’s a gold mine for rebounds, steals, and blocks from the wing.

    ⭐ Alperen Şengün (HOU) – Massive upside if healthy

    A top-20 fantasy player when given full minutes; elite passing for a center elevates his ceiling.

    ⭐ Keegan Murray(SAC) – Underrated across-the-board contributor and good shooter

    Sacramento’s lack of youth will push heavy minutes and production from him.

    3. Veterans Who Still Deliver

    Fantasy isn’t just about youth. Some reliable vets still outperform ADP year after year.

    🔵 LeBron James

    Even with age concerns, his all-around contributions make him extremely valuable in roto.

    🔵 James Harden

    His scoring is down, but the assists and threes remain elite.

    🔵 Domantas Sabonis

    Triple-double threat every night with league-leading rebound potential.

    4. In-Season Management Tips

    Work the Waiver Wire Early

    The first 2–3 weeks decide the breakout pickups that can win leagues (think 2023’s Tyrese Maxey or 2024’s Dereck Lively II).

    Stream Smartly

    Use the schedule to your advantage. Games on lighter days (Monday/Thursday) offer more value.

    Sell High Before Regression Hits

    If a role player is shooting 58% from three or playing above expectations due to injuries, capitalize.

    Pay Attention to Coaching Rotations

    A coach’s trust can turn a bench player into a fantasy gem overnight.

    🔄 Buy-Low Trade Targets (Week 6)

    Players who are underperforming but expected to rebound.

    1. Karl-Anthony Towns

    Slow start? Maybe. But the efficiency, threes, and rebounds will normalize. Still elite in roto formats.

    2. Trae Young

    If someone in your league is frustrated with percentages and turnovers, swoop in. His counting stats are always top-tier.

    3. LaMelo Ball

    If injuries have limited his early-season production, he’s a prime buy-low. His ceiling is top-10 when healthy.

    📈 Sell-High Candidates (Week 6)

    Players performing above their realistic season-long value.

    1. Tobias Harris

    He always starts hot, but usage drops as the season goes on. If you can flip him for a top-40 guy, do it.

    2. Malik Monk

    Super valuable, but his scoring streaks are role-dependent. A great sell-high in points leagues.

    3. Brook Lopez

    The blocks are elite—but historically inconsistent. If he’s on a heater, cash in.

  • Volunteering

    Over the past few weeks, I’ve had the opportunity to volunteer with two incredible organizations: Aquameridian and Kids Against Hunger. Each group focuses on tackling critical issues in our communities and beyond. These experiences reinforced the idea that small efforts, when multiplied, can create real and lasting change.

    Last week, I joined Aquameridian to help clean up a beach near Alameda, California. Aquameridian is a project driven by the belief that consistent, local action can lead to meaningful environmental progress. Picking up trash might seem like a small task, but it plays a significant role in preserving our natural spaces and protecting marine life. When communities come together for causes like this, we are not just cleaning up; we are building awareness and setting a standard for environmental responsibility.

    Just the week before, I volunteered with Kids Against Hunger, a nonprofit organization focused on fighting food insecurity among children. There, I helped package meals to be distributed to areas where kids lack consistent access to nutritious food. Hunger, much like pollution, is a complex global issue. But even a few hours of volunteer work can directly impact the lives of those in need.

    The beauty of volunteering is that it benefits everyone. Whether you are improving your local neighborhood, supporting global humanitarian efforts, or simply growing as a person, every action has a ripple effect. You do not need to start big to make an impact. You can donate, raise funds, volunteer for existing nonprofits, or even create your own initiative.

    In fact, I’m currently working on a personal project to address illegal trash dumping in California. One of the biggest challenges in reporting dump sites is the confusing and overlapping jurisdiction system across districts. It is often unclear which agency is responsible, and this leads to delays or inaction. My app aims to simplify this process by identifying the correct organization based on location and pre-filling reporting forms. This makes it much easier for residents to take action.

    Whether it is packing meals, cleaning beaches, or building tools to streamline civic engagement, all of these efforts move us closer to a healthier and more equitable world. With enough small steps in the right direction, we can begin to solve massive problems and create meaningful change.

  • Understanding MRI

    And the whistle sounds… If you watch physical sports, you see it all the time. An injured player carted off left to the fate of analysis by machinery. Thankfully, healthcare has become extremely advanced as a result of engineering. MRI, or Magnetic Resonance Imaging, is a very advanced diagnostic apparatus in contemporary medicine. MRI is a tool that provides high clarity of pictures of the body’s inner structure to the doctors, starting from recognizing a knee torn ligament to spotting a brain tumor and doing so without the use of an ionizing radiation beam that can harm the body. Therefore, it serves as a very useful tool to examine time-conditioned illnesses or to scrutinize precarious parts of the body such as the brain or reproductive organs.

    MRI is a completely freestanding, non-invasive imaging modality for soft tissue, three-dimensional high-resolution images production. MRIs have become an indispensable diagnostic tool for the medical field and are used for the detection of a vast range of diseases and traumas, monitoring of treatment responses, and to check out abnormal symptoms. MRI is entirely non-penetrative, as opposed to X-rays and CT scans. This is because it does not use ionizing radiation, thus it is a far better alternative to patients who require several scans over a prolonged duration.

    The physics of MRI is based on the magnetic characteristics of hydrogen protons, which are abundant in water and fat molecules in the human body. The technique follows a few simple procedures:

    1. Magnetism: A sizable, powerful magnet surrounds the patient. The hydrogen protons in the body all align in a similar direction because of the attraction from a magnetic field.
    2. Radiofrequency Pulse: A quick burst of radio waves enters the body and causes the protons to shift out of their previous alignment.
    3. Signal detection: The protons return to their initial alignment when the radiofrequency pulse stops. They release small amounts of energy as they move.
    4. Image Creation: This newly released energy is detected by special sensors, and sophisticated computer algorithms use the information to create finely detailed images of the tissues.

    In other places, the heterogeneous tissues like muscle, fat, and nerve fibers, behave dissimilarly due to their water content and microscopic structure. This is the variation in response that helps radiologists identify one type of tissue from the other in the images. This enables them to detect injuries, growths, or other signs of disease.

    MRI is frequently used for imaging soft tissues and configurations that are prone to poor visuality by other modalities like x-rays for instance. X-rays can only detect bone-like structures, ignoring finer details like soft tissue. Some well-known applications are:

    • Brain and spinal cord: Detecting tumors, aneurysms, strokes, multiple sclerosis, and nerve injuries.
    • Joints: Evaluating ligament and tendon damage, such as in knees, shoulders, or wrists.
    • Muscles and internal organs: Assessing damage from trauma, detecting inflammation, or spotting abnormal growths.

    By combining powerful magnets, radio waves, and advanced computing, MRI machines allow doctors to see inside the body in extraordinary detail. This in turn helps them make accurate diagnoses and plan effective treatments while keeping patient’s privacy and health safe.
