pulses

Scientists are tracking a slow-moving kelvin wave, a vast pulse of warm ocean water travelling along the equatorial Pacific toward the US West Coast. The phenomenon is closely tied to El Niño-Southern Oscillation dynamics, and observers warn it could shift weather patterns, raise coastal sea levels and influence storm activity for California in the months ahead, sharpening fears of extreme conditions on the West Coast.

As solar and wind replace conventional power plants, grids lose the natural inertia that traditionally kept frequency stable, raising concerns about blackout risks. UK-based Reactive Technologies is addressing this by sending sonar-like pulses through the grid to measure live inertia directly, revealing risks that standard models miss. The company has received €19 million in backing from the European Investment Bank to expand the approach.

A Kelvin wave is an underwater pulse of unusually warm water that travels eastward along the equator in the Pacific. Meteorologists are watching current Kelvin activity because such waves can push warm water toward the coast, influencing ocean temperatures, marine life, and weather patterns, and potentially shaping conditions that could affect California's climate outlook.

Astronomers report that a stellar remnant, described as a zombie star, is repeatedly flashing toward Earth as it wobbles, with the pulses apparently caused by a large expelled cloud of gas. Researchers are calling the observations groundbreaking, saying they offer a rare look at the behavior of a star after it has survived or undergone an explosive event.

US lawmakers and agriculture industry watchers are turning their attention to a busy week in Washington, with farm bill politics at the center of debate. Agri-Pulse reports that the fuel outlook, including ethanol and biofuel policy, and the trade outlook for US agricultural exports are also in focus as negotiators weigh next steps on the long-stalled farm bill.

Equifax's Second Quarter 2026 Market Pulse Index Report finds the first pause in K-shaped economic widening in three years. The K-shaped pattern refers to a divergence in which higher-income consumers and stronger sectors pull ahead while lower-income households and weaker sectors fall behind. A pause suggests that gap stopped widening this quarter, though the report gives no further detail in the available headline.

The Albuquerque Journal takes readers inside Sandia National Laboratories' Z machine in New Mexico, the world's most powerful pulsed-power facility. Originally built to study materials under nuclear weapons conditions, the device is now central to research on fusion energy, exploring how the same physics that powers warheads could one day deliver clean, abundant power.

Florida Atlantic University has released the September 2026 edition of Pulse Check, a feature with Dean Nelson. The item appears to be an update from the university, but no further details about its content or reception are available at this time.

Attention on El Niño is rising as meteorologists explain a 'planetary-scale Kelvin wave' — a massive pulse of warm water moving eastward along the equatorial Pacific. The Weather Network reports the phenomenon is strengthening the El Niño pattern and is fueling concern in California, where it can drive heavy winter storms and flooding, while also altering weather patterns worldwide.

J3 side Zweigen Kanazawa host J1 club Shimizu S-Pulse on the 29th in the second round of the Levain Cup. Shimizu are expected to field a squad close to full strength, with local reports urging the side to stay focused and take the win without giving their lower-division opponents any opening.

A newly published book argues that Northern Michigan could become a refuge for people seeking safer places to live as climate change intensifies elsewhere in the United States. Coverage from Great Lakes Echo and Lansing City Pulse highlights the book's exploration of the region's climate haven potential, including its water resources and relative insulation from extreme heat, wildfires and sea-level rise.

A Green Bay Packers fan has spoken out after a pulse check at Lambeau Field set off a wave of reaction online. The story has been picked up by sports outlets including Yahoo Sports, with fans debating the moment across social media. Details of exactly what happened at the stadium remain limited, but the fan's response has kept the story circulating.

A Kelvin wave, a pulse of unusually warm water moving eastward along the equatorial Pacific, is reported to be heading toward the US West Coast and California. Such waves are closely watched because they can influence ocean temperatures, marine ecosystems and coastal weather patterns, and they sometimes foreshadow El Nino conditions. Coverage so far is limited to environmental outlets, with no detailed regional response reported yet.

Agri-Pulse's latest Farm Hands on the Potomac roundup reports several personnel moves in agriculture and nutrition policy circles. The National Grocers Association has brought on Mike Ridenour, SAM Nutrition has added Erika Wederquist, and BASF Agricultural Solutions has named Leta LaRush senior vice president for its U.S. business. The column tracks staff and executive changes across the agri-food sector in Washington.

NASA is using light-detecting technology to take the pulse of Puerto Rico's forests, tracking how these ecosystems are recovering and changing. The project measures forest health and structure by analysing how light interacts with the canopy, offering scientists a detailed picture of tropical forest conditions in the region.

A powerful Kelvin wave — a pulse of unusually warm water moving eastward along the equator beneath the ocean surface — is expected to arrive off the California coast as El Niño conditions strengthen. Scientists say the warm water could reinforce the El Niño pattern, influencing storms, coastal temperatures and rainfall across the West Coast in the coming weeks and months.

The US Department of Agriculture is facing a lawsuit challenging its decision to restrict solar funding under a rural energy program. The suit, reported by agricultural news outlet Agri-Pulse, contests the department's limits on how much support solar projects can receive. The case highlights ongoing tensions over federal support for renewable energy in rural America.

Indian tech brand Ai+ has entered the tablet market, launching its first tablets, the NovaTab and Nova LapTab 5G, alongside the Ai+ Pulse 2 FE device. The company, which has so far focused on releasing a range of smartphones in India, is expanding its product lineup into new categories. Details on pricing and specifications are being shared as the devices debut.
