Happy Wednesday, Cultivators of Curiosity!
Welcome to the 34th volume of The Point by Modern Sciences! This issue brings you to the cutting edge of environmental innovation and provides crucial insights into climate change.
First, discover a game-changing, eco-friendly chemical that offers a safer and more effective way to control destructive drywood termites, providing a much-needed alternative to traditional fumigation. Then, journey deep beneath the Earth's surface with us to uncover newly discovered soil microbes that play a vital role in purifying our water and facilitating nutrient cycling—a discovery that could unlock future solutions to environmental pollution. Finally, we break down the two key ingredients that cause extreme storms and explain why these destructive downpours are happening more frequently, offering a clearer understanding of climate change's direct impact on our weather patterns. Dive into these fascinating stories and understand the science shaping our world.
ENGINEERING
New Chemical Offers Eco-Friendly Solution for Controlling Destructive Drywood Termites
University of California, Riverside researchers have identified bistrifluron as an eco-friendly solution for controlling destructive drywood termites. Unlike traditional methods, this chemical targets the termites’ exoskeletons, preventing them from molting and leading to their death. With minimal toxicity to humans and lasting protection against future infestations, bistrifluron offers a promising, sustainable alternative for termite control, mainly as climate change drives these pests into new regions.
The Point:
Bistrifluron disrupts termite growth: Researchers found that bistrifluron, a chemical that blocks molting by targeting termite exoskeletons, can eliminate colonies without harming humans.
Effective alternative to fumigation: Unlike toxic fumigation methods, bistrifluron-treated wood gradually and safely spreads the chemical through termite colonies, offering a lasting and less invasive solution.
Long-term pest control promise: The study shows that bistrifluron remains active in wood over time, and researchers aim to optimize its real-world use for broader, climate-resilient termite control.

Newly Discovered Soil Microbes Help Purify Water Deep Below Earth's Surface
Researchers, led by James Tiedje from Michigan State University, discovered a new group of microbes, CSP1-3, deep in the soil that helps purify water and recycle nutrients. Found in Iowa and China, these microbes, previously thought to be dormant, actively support water filtration and ecosystem health. Their study could offer solutions for environmental challenges like pollution cleanup.
The Point:
A new group of deep-soil microbes has been discovered: Researchers identified CSP1-3, a highly abundant and active microbial group found as deep as 70 feet underground. This discovery revealed an unknown ecosystem within Earth's "Critical Zone."
CSP1-3 plays a vital role in nutrient cycling and water purification: These microbes actively recycle carbon and nitrogen in deep soils, helping purify water as it filters through the ground, thus supporting soil health and clean groundwater supplies.
Future studies may unlock solutions to environmental pollution: Scientists aim to culture CSP1-3 in the lab to explore its genetic traits, hoping to harness its capabilities for pollution cleanup and advancing global environmental sustainability.

Two key ingredients cause extreme storms with destructive flooding – why these downpours are happening more often
Extreme storms form when warm, moisture-laden air meets strong atmospheric instability, creating sustained, high-energy systems. As global temperatures rise, air holds more moisture, and wind patterns shift, intensifying storms and slowing their movement. This combination increases the risk of prolonged rainfall, flooding, and tornado outbreaks, making events like April’s deadly Midwest storm more frequent and destructive.
The Point:
Ingredients for Extreme Storms: Extreme storms require two key conditions: moisture and atmospheric instability. The moisture needed for storms comes from evaporation, and the warmer the air, the more moisture it can hold. Atmospheric instability arises from rising air and wind shear, which together fuel storm systems capable of producing heavy precipitation and tornadoes.
Role of Climate Change in Storms: Global warming exacerbates conditions conducive to extreme storms. Warmer air can hold more moisture, increasing precipitation, while the warming of the polar regions weakens global winds and slows the movement of storms. This leads to prolonged storm systems, as seen in the April 2025 storm event, where stalled fronts caused extensive rainfall and flooding.
Prolonged Storm Systems and Future Impacts: The April storm system in the Midwest and Southern U.S. was caused by a clash between warm and cold air masses, slowed by reduced temperature differences. This stalling allowed for prolonged precipitation and repeated storm cycles. With global warming intensifying these factors, future storms are expected to be more frequent, severe, and likely to cause greater flooding.
