The U.S. Is Spending Billions to Reduce Forest Fire Risks – We Mapped the Hot Spots Where Treatment Offers the Biggest Payoff for People and Climate
In a new study, my colleagues and I mapped out where forest treatments can do the most to simultaneously protect communities – by preventing wildfires from turning into disasters – and also protect the forests and the climate we rely on, by keeping carbon out of the atmosphere and stored in healthy soils and trees.

New Quantum Device Generates Single Photons and Encodes Information
Innovative approach is a step toward using single photons in quantum communication and information processing. Further coupling of the photon stream into waveguides — microscopic conduits of light — would provide the photonic circuits that allow the propagation of photons in one direction. Such circuits would be the fundamental building blocks of an ultra-secure quantum internet.

Chipmaker Nvidia Strikes AI Gold
The artificial intelligence boom has seen Nvidia achieve stunning financial results. Shares in the Silicon Valley company hit an all-time high, after its revenue doubled year-on-year in the second quarter of 2023 to $13.5 billion. But other companies, including Google, Microsoft and Amazon, want a piece of the action.

North America’s Summer of Wildfire Smoke: 2023 Was Only the Beginning
Canada’s seemingly endless wildfires in 2023 introduced millions of people across North America to the health hazards of wildfire smoke. While Western states have contended with smoky fire seasons for years, the air quality alerts across the U.S. Midwest and Northeast this summer reached levels never seen there before. The pressing question on many people’s minds: “Is this the new normal?” From our perspective as air quality scientists, we think the answer is likely “yes.”

How Much Wave Energy Is in Our Oceans?
The ocean is never still, but exactly how much energy surges through our ocean waves is a matter of debate. That uncertainty makes it challenging for countries to weave wave energy into their future climate goals. New study could help countries better estimate how much power their waters carry.

The U.S. and China May Be Ending an Agreement on Science and Technology Cooperation − a Policy Expert Explains What This Means for Research
A decades-old science and technology cooperative agreement between the United States and China was set to expire on Aug. 27, 2023, but was extended, at the last minute, by six months to allow more negotiations between the two countries. On the surface, an expiring diplomatic agreement may not seem significant. But unless it’s renewed, the quiet end to a cooperative era may have consequences for scientific research and technological innovation, as the U.S. risks being cut off from top know-how as China forges ahead.

A Tropical Storm in California? Warmer Waters and El Niño Made It Possible.
Tropical Storm Hilary made landfall in Mexico and crossed into California last weekend, knocking out power and drenching wide swaths of southern California. Los Angeles received 2.48 inches of rain on Sunday, breaking a single-day record from 1906 of 0.03 inches. Storm Hilary adds to the lengthy list of climate-fueled disasters this summer.

Sediment Movement During Hurricane Harvey Could Negatively Impact Future Flooding
Enormous amounts of sediment, or sand and mud, flowed through Houston waterways during Hurricane Harvey in 2017, due in part to modifications made by humans to bayous, rivers and streams over the past century. Harvey was the largest rainfall event in U.S. history, and it moved 27 million cubic meters of sediment, or 16 Astrodomes, through Houston waterways and reservoirs. This could seriously impact future flooding events and be costly to the City of Houston.

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
By Trina West
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
