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.

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.

Standardizing Encryption Algorithms That Can Resist Attack by Quantum Computers
Last year, the National Institute of Standards and Technology (NIST) selected four algorithms designed to withstand attack by quantum computers. Now the agency has begun the process of standardizing these algorithms — the final step before making these mathematical tools available so that organizations around the world can integrate them into their encryption infrastructure. Three new algorithms are expected to be ready for use in 2024. Others will follow.

Nuclear Has Changed. Will the U.S. Change with It?
Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.
Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
Exploring the New Nuclear Energy Landscape
In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.
