The first round of negotiations between US and Iranian delegations concluded Sunday near Lake Lucerne, Switzerland, with mediating parties Qatar and Pakistan calling the results encouraging progress. Vice President JD Vance led the American delegation; Iranian Foreign Minister Abbas Araqchi represented Tehran. The two sides established a High Level Committee and agreed on a roadmap toward a final deal within 60 days, with technical talks to continue on Iran's nuclear program, sanctions relief, frozen assets, reconstruction funding, and a deconfliction mechanism for the Strait of Hormuz. Araqchi described the summit as producing major progress toward ending the Lebanon war. The talks follow a memorandum of understanding signed last week that drew criticism from Israeli officials and some US lawmakers, who argue the deal benefits Iran more than the US. Trump complicated matters Sunday by threatening to hit Iran very hard again over Hezbollah activity, raising questions about the 60-day timeline.
The US and Iran have been in active military conflict since late 2025, when US strikes against Iranian nuclear facilities triggered a broader escalation involving Hezbollah and Israeli operations in Lebanon. An MOU signed last week established the 60-day negotiating framework now underway, with Qatar and Pakistan serving as mediators.
France is bracing for the worst heat in more than two decades as temperatures climb toward 42 degrees Celsius in central and western regions. Meteo-France issued red alerts across 35 departments and orange alerts across 40 more, affecting roughly 53 million people combined. The agency calls the episode exceptional in intensity, drawing comparisons to the deadly heatwaves of 2003 and 2019. Schools have shut across 845 establishments, 71 SNCF intercity train routes are cancelled due to rail stress, and road speed limits have been cut in several areas. Three residents aged 80 to 95 died in the Gironde region, along with four drowning deaths as people sought relief in water. Temperatures are expected to peak Monday through Thursday, with isolated spots potentially reaching 43 degrees. The health minister warned many citizens will suffer, with the elderly and those without air conditioning at greatest risk in Paris and other urban centers.
France's 2003 heatwave killed approximately 15,000 people, most of them elderly living alone. The 2019 heatwave set a national temperature record of 45.9 degrees Celsius and caused widespread rail and school disruptions. European summers have grown significantly hotter as the climate warms, with severe heatwaves now arriving more often and lasting longer.
Russia has positioned up to 250 troops inside Kostyantynivka, a city in eastern Ukraine that both sides view as a gateway to the broader Donbas region. If Russian forces take the city, they can push toward Kramatorsk and Sloviansk, Ukraine's last remaining strongholds in Donetsk Oblast, potentially completing Moscow's campaign to seize the full territory it annexed in 2022. Ukrainian soldiers in the city are not receiving enough reinforcements to cover their losses, and one military observer warned that Russia may capture Kostyantynivka by the end of summer. Russian forces have found ways to advance through zones where Ukrainian drones normally detect all movement. The city also functions as a key rail and road hub supplying Ukrainian positions further east, meaning its fall would degrade logistics across the front.
Russia formally annexed four Ukrainian regions in September 2022, including Donetsk Oblast (Donbas), but has not fully controlled any of them. Kostyantynivka sits roughly 20 km from the current front line. Kramatorsk and Sloviansk, the two larger cities behind it, serve as the main population and administrative centers for Ukrainian-held Donbas.
The White House budget office, led by Director Russell Vought, has proposed a rule that would let political appointees cancel or redirect federal grant funding for virtually any reason, with little opportunity for recipients to appeal. The change would apply to over $1 trillion in annual grants that currently flow to state governments, universities, cancer researchers, bridge engineers, and public health organizations. Under existing rules, grant recipients can challenge arbitrary funding cuts through formal processes. The proposed rule would strip most of those protections, placing discretionary control with presidential appointees. Critics describe it as carte blanche politicization of a funding process that is supposed to reward merit and mission. The proposal arrives as many research universities are already managing federal grant freezes and targeted cuts tied to compliance disputes over DEI policies and Title VI enforcement.
The Office of Management and Budget sets the rules under which federal agencies distribute grants. Current regulations give recipients due process protections when agencies try to pull approved funding. Vought, a veteran of both Trump administrations and a key architect of Project 2025, has argued that career bureaucrats have too much independence from presidential control.
Princeton's faculty voted in May to require proctors for all in-person exams starting July 1, ending a tradition dating to 1893. The reason is AI. A survey of Princeton seniors found nearly 30 percent had cheated, 44 percent had seen a classmate cheat and said nothing, and fewer than 1 percent had ever reported a peer. Stanford's faculty senate voted the same month to allow proctoring after a pilot program. The core problem is that AI-assisted answers are hard to detect without watching students in real time. Honor codes were built on social norms and peer accountability; AI undermines both by making violations invisible. Universities now face two paths: restore surveillance through proctors, or redesign assessment toward open-tool problems that require original reasoning rather than memorized knowledge, mirroring what employers actually evaluate. Both approaches are now underway, and experts say they are not mutually exclusive.
Honor codes originated at US universities in the 19th century as a way to cultivate academic integrity without surveillance. Students pledged not to cheat and were expected to report violations by peers. Princeton's system, established in 1893, had gone 133 years without requiring instructors to observe exams. AI is the first threat to the model that universities have found hard to counter without abandoning the underlying assumption of mutual trust.
EPFL, ETH Zurich, and the Swiss National Supercomputing Centre released Apertus, a large language model that differs from most open-source AI in a precise way: it publishes not just the weights but the training data, source code, training pipeline, and methods, all documented and reproducible. The model comes in 8-billion and 70-billion parameter versions and was trained on 15 trillion tokens covering more than 1,000 languages, with 40 percent of training data drawn from non-English sources, including lower-resource languages such as Swiss German and Romansh. Apertus was designed to satisfy EU AI Act requirements, including removal of personal information from training data and prevention of memorization. A paper describing the system was accepted at ACL 2026. The project is intended as a template for sovereign AI, meaning infrastructure that governments and research institutions can fully audit and operate without depending on closed commercial models from US or Chinese labs.
Most AI models marketed as open release only their weights, not the training data or training pipeline. Llama 4 and similar models follow this pattern. A small group including OLMo from the Allen Institute release the full training stack. Apertus joins that category, backed by Swiss federal research funding and built to operate across Europe's regulatory environment.
Two Democratic Socialists of America candidates won major mayoral contests this month, extending a winning streak following Zohran Mamdani's election as New York City mayor. In Washington, D.C., Janeese Lewis George won the Democratic primary and is nearly certain to succeed Mayor Muriel Bowser. In Los Angeles, Nithya Raman, a city council member affiliated with DSA, advanced to a runoff against incumbent Karen Bass. DSA membership has grown from about 70,000 in 2025 to over 100,000 as the group rides frustration with mainstream Democratic politics during the second Trump administration. The wins do not mean most Democratic voters have moved left: Lewis George narrowly defeated a moderate opponent, and Raman still faces a runoff. But they do signal that democratic socialism is no longer a fringe position in major American cities, and that the DSA's model of running candidates inside the Democratic primary rather than as a third party is producing results.
The Democratic Socialists of America is the largest socialist organization in the US, with roots in the Bernie Sanders campaigns of 2016 and 2020. Unlike European social democratic parties, DSA is not a ballot-line party but a political organization that endorses candidates who run as Democrats. Mamdani's New York mayoral win was the group's most prominent victory before this month's results.
A systematic review of five randomized controlled trials presented at ENDO 2026, the Endocrine Society's annual meeting, found that GLP-1 medications may raise testosterone levels in men with obesity. A Mayo Clinic retrospective of 1,600 men found testosterone rose about 30 percent after GLP-1 treatment; a separate study of 215 men found levels averaged 20 percent higher. The mechanism runs through fat tissue: fat cells contain enzymes that convert testosterone into estradiol, the primary female sex hormone, and losing weight via GLP-1 reduces that conversion. Two of the five trials also found improvements in sperm quality. The findings matter for clinical practice because testosterone replacement therapy, the current standard for low testosterone in obese men, actually worsens sperm quality, making it a poor option for men who want to preserve fertility. GLP-1 may offer a path that addresses both problems.
GLP-1 receptor agonists, a drug class that includes semaglutide (sold as Ozempic and Wegovy), were originally developed for type 2 diabetes. They produce significant weight loss by slowing gastric emptying and reducing appetite signals in the brain. They are now among the most prescribed drug classes globally, with research continuing to find secondary health effects beyond weight.
A math essay by Alex Kritchevsky making the rounds on Hacker News argues that logarithms are not merely one of many tools in mathematics but a foundational primitive that appears across dozens of fields under different names and notation. The key move is to treat logarithms as baseless objects, abstract quantities that acquire numerical values only when expressed relative to a chosen unit (the base), exactly as a vector exists independently of any coordinate system. From that vantage, p-adic valuations in number theory, the order of vanishing of a complex function, and the dimension operator in linear algebra all turn out to be the same underlying object in different clothing. The change-of-base formula becomes a coordinate transformation. The essay proves nothing technically new but offers a reframe that unifies a scattered collection of graduate-level facts into a single picture, making explicit connections that most textbooks leave implicit.
P-adic valuations are a number-theory tool that extracts how many times a prime divides an integer; the order of vanishing measures how a complex function approaches zero near a point. Both appear in separate courses without the connection to logarithms made explicit. Kritchevsky's argument is that the connection is not incidental but structural.
A software engineer named David Newgas published an essay asking a question AI has made newly relevant: did the startup he worked at exist because the venture firm needed it to, rather than because the technology was worth building? Newgas worked at GenieDB, a UK database startup acquired by Frost VP, a venture incubator. The SEC later sued Frost VP's founder Stuart Frost for running a scheme in which portfolio companies were selected not for business merit but for the fees they paid the incubator. An internal Frost email read: Right now we need 2 more companies to cover our costs, with Genie coming out in June. GenieDB's CEO testified the company paid excessive fees. Newgas concludes he was not purely an instrument of fraud, the technology had real merit that later proved out at better-resourced companies, but the question lingers: in a world where venture firms earn management fees on deployed capital regardless of outcomes, how many startups exist to justify the fee structure rather than the other way around?
