Yiannis Levendis, a professor at Northeastern University, has developed a robotic firefighting prototype that uses liquid nitrogen to rapidly extinguish wildfires without harming the environment. The system is designed to reach hazardous fire hotspots that may be difficult or unsafe for firefighters to access, offering an alternative approach to early wildfire suppression.
Levendis observed that liquid nitrogen could rapidly extinguish flames by expanding into gas and reducing the oxygen available for combustion. Unlike conventional wildfire retardants, the cryogenic approach leaves no chemical residue, potentially reducing environmental impacts on soil and nearby water bodies.
To deliver the cryogenic agent, the research team built an all-terrain robotic platform equipped with caterpillar tracks and a spray system. The prototype is being evaluated on controlled fires using vegetation commonly found in wildfire-prone forests in the western U.S.

The Russian government has issued a decree banning crypto mining and participation in mining pools in Moscow, the surrounding Moscow region, and parts of the Kursk region from Aug. 15 until the end of 2032.
The measure finalizes a proposal published by the country’s Energy Ministry in late June, which included an explanatory note that said the affected territories could face electricity shortages if the mining activities were not prohibited year-round.

The U.S. Federal Trade Commission cleared quantum computing firm IonQ's $1.8 billion acquisition of chipmaker SkyWater Technology, the largest semiconductor foundry based in the U.S., after the agency's leaders disagreed over whether to impose conditions.
Chairman Andrew Ferguson proposed requiring IonQ to agree to granting fair access to rival quantum computing companies, some of whom have ongoing contracts with SkyWater, among other measures to protect competition as the U.S. adds chip manufacturing capacity.

Venezuela’s government and some opposition members formally launched a US-backed political dialogue that could establish the terms for future democratic elections. Representatives of the government-controlled National Assembly and members of the 2015 opposition-led National Assembly had a phone call on Saturday.
The parties established technical working groups that are expected to begin in-person meetings next week in Caracas. The groups will discuss the response for the victims of the recent twin earthquakes, strengthening democracy and political rights and guarantees.

Moroccan King Mohammed VI said his decision to give US President Donald Trump’s name to a $1 billion highway that crosses into the disputed Western Sahara expresses his “deep appreciation” of the American leader.
In a letter reported by state news agency MAP, the North African monarch confirmed the 1,055-kilometer (660 miles) expressway between Tiznit and the Western Sahara city of Dakhla will be called the Donald J. Trump Highway.

Major OPEC+ nations have agreed in principle to another token increase in their production quotas for September, a move that would complete the theoretical revival of supplies halted in 2023 and give them scope to add more barrels once the Middle East war ends.
Seven members led by Saudi Arabia and Russia are likely to agree to boost their collective target by a further 188,000 barrels a day next month, two delegates said.

Researchers from China’s national police academy have developed an AI framework that can detect illicit cryptocurrency transactions with nearly 90% overall accuracy, according to a recent study.
In an article published in the peer-reviewed Chinese publication Journal of Intelligence, corresponding author Dr Sun Jingchao wrote that the study “provides a precise, generalisable and interpretable solution for detecting illicit cryptocurrency transactions”.
It also “provides an innovative technological pathway for regulatory authorities to combat illicit cryptocurrency transactions and economic crimes”, Sun, a researcher specialising in criminal investigation and cybersecurity, wrote.

Growing populations and expanding industries are worsening freshwater shortages across Africa, the Middle East, and Southeast Asia, increasing demand for sustainable water supplies. Solar desalination uses sunlight to produce freshwater efficiently, but oil contamination in seawater can clog desalination membranes and reduce their performance.
In an effort to overcome this limitation, researchers at Pusan National University developed a multifunctional hydrogel membrane that combines oil separation and solar-driven desalination in a single system. The study was published online on June 1, 2026, and will appear in the October 15, 2026, issue of Desalination.
Testing showed that the membrane removed more than 99.99% of oil from contaminated seawater while maintaining stable performance across different oil droplet sizes and repeated cycles. It represents a broader strategy for designing next-generation water treatment technologies.

“We have to move away from this image of the brain as a machine made of gears, with every gear having an exact purpose that we can attach a label to,” — said Stefano Fusi, PhD, a principal investigator at Columbia’s Zuckerman Institute, a member of the Kavli Institute for Brain Science.
“The brain doesn’t work like that. Instead, most neurons can display a huge diversity of responses, and this can help the brain solve a huge number of different tasks.”
Most neurons may be far more versatile than scientists once thought. In a major study published in Nature, researchers analyzed more than 14,000 individual neurons across 43 regions of the mouse cortex and found that most didn't perform one clearly defined job. Instead, they responded to shifting combinations of sensory information, movement, and decision-making.
A neuron that appears devoted to one feature under certain conditions may also encode several other pieces of information. That flexibility could help explain how the brain handles new situations without requiring a separate group of cells for every possible experience.

The controversial billionaire tax won the backing of the California Democratic Party, the latest twist in the drama surrounding a measure that has roiled the left and its allies. The party’s executive board voted Sunday to endorse Proposition 40, which, if approved by voters in November, would impose a 5% one-time tax on billionaires’ assets to pay for healthcare.
The measure has proved divisive. Although it has support from progressives including Sen. Bernie Sanders (I-Vt.) and Rep. Ro Khanna (D-Fremont), others including Gov. Gavin Newsom, gubernatorial candidate Xavier Becerra, and a growing list of labor unions have come out against it, arguing the one-time nature of the tax and billionaire flight could cause more harm than good to California’s state budget.
