"Microsoft has released the source code for the GitHub Copilot Chat extension for VS Code under the MIT license," reports BleepingComputer. This provides the community access to the full implementation of the chat-based coding assistant, including the implementation of "agent mode," what contextual data is sent to large language models (LLMs), and the design of system prompts. The GitHub repository hosting the code also details telemetry collection mechanisms, addressing long-standing questions about data transparency in AI-assisted coding tools...

As the VS Code team explained previously, shifts in AI tooling landscape like the rapid growth of the open-source AI ecosystem and a more level playing field for all have reduced the need for secrecy around prompt engineering and UI design. At the same time, increased targeting of development tools by malicious actors has increased the need for crowdsourcing contributions to rapidly pinpoint problems and develop effective fixes. Essentially, openness is now considered superior from a security perspective.
"If you've been hesitant to adopt AI tools because you don't trust the black box behind them, this move opensources-github-copilot-chat-vscode/offers something rare these days: transparency," writes Slashdot reader BrianFagioli" Now that the extension is open source, developers can audit how agent mode actually works. You can also dig into how it manages your data, customize its behavior, or build entirely new tools on top of it. This could be especially useful in enterprise environments where compliance and control are non negotiable.

It is worth pointing out that the backend models powering Copilot remain closed source. So no, you won't be able to self host the whole experience or train your own Copilot. But everything running locally in VS Code is now fair game. Microsoft says it is planning to eventually merge inline code completions into the same open source package too, which would make Copilot Chat the new hub for both chat and suggestions.

This week America's Energy Department selected two companies to perform the first nuclear microreactor tests in a new facility in Idaho, saying the tests "will fast-track the deployment of American microreactor technologies... The first fueled reactor experiment will start as early as spring 2026."

The new facility is named DOME (an acronym for Demonstration of Microreactor Experiments), and it leverages existing "to safely house and test fueled reactor experiments, capable of producing up to 20 megawatts of thermal energy," according to a local newspaper. [T]wo companies were competitively selected in 2023 and are currently working through a multi-phase Energy Department authorization process to support the design, fabrication, construction, and testing of each fueled reactor experiment. Both are expected to meet certain milestones throughout the process to maintain their allotted time in DOME and to ensure efficient use of the test bed, according to the release... The department estimates each DOME reactor experiment will operate up to six months, with the DOME test bed currently under construction and on track to receive its first experiment in early 2026... The next call for applications is anticipated to be in 2026.
The site Interesting Engineering calls the lab "a high-stakes proving ground to accelerate the commercialization of advanced microreactors..." Based in Etna, Pennsylvania, Westinghouse will test its eVinci Nuclear Test Reactor, a compact, transportable microreactor that uses advanced heat pipe technology for passive cooling. Designed to deliver 5 megawatts of electricity on sites as small as two acres, eVinci could support applications ranging from remote communities to mining operations and data centers. Meanwhile, Radiant (El Segundo, California) will test its Kaleidos Development Unit, a 1.2 megawatt electric high-temperature gas reactor aimed at replacing diesel generators. Designed to run for five years, Kaleidos is fueled by TRISO fuel particles that could offer reliable backup power for hospitals, military bases, and other critical infrastructure.
Radiant's CEO said "In short order, we will fuel, go critical, and operate, leading to the mass production of portable reactors which will jumpstart American nuclear energy dominance."

Some of the water around Antarctica has been getting saltier. And that has affected the amount of sea ice at the bottom of the planet. From a report: A study published Monday in the Proceedings of the National Academy of Sciences found that increases in salinity in seawater near the surface could help explain some of the decrease in Antarctic sea ice that have been observed over the past decade, reversing a previous period of growth.

"The impact of Antarctic ice is massive in terms of sea-level rise, in terms of global warming, and therefore, in terms of extremes," said Alessandro Silvano, a senior scientist at the University of Southampton studying the Southern Ocean and lead author of the study. The findings mean "we are entering a new system, a new world," he said. The Times adds: "the Department of Defense announced it would be no longer be providing some of the satellite data that researchers use to monitor changes in sea ice."

Climate change is already having an impact on companies around the world. More than half of companies surveyed by Morgan Stanley experienced climate-related operational disruptions within the past year, including increased costs, worker disruption and revenue losses. Extreme heat and storms caused the most frequent disruptions, followed by wildfires and smoke, water shortages, and flooding.

The US spent nearly $1 trillion on disaster recovery and climate-related needs over the past year, according to Bloomberg Intelligence analysis, while nearly two-thirds of Tampa metro businesses reported losses from hurricanes Helene and Milton.

The US dollar is on track for its worst year in modern history and may not be done falling yet. The greenback is down more than 7% this year and Morgan Stanley predicts it could fall another 10%. Semafor: A weaker dollar could make US exports more competitive, boosting Trump's plan to rebalance US trade, but makes imports more expensive, adding to the sting of tariffs.

The question ahead is whether the dollar doesn't just lose its value, but its role at the center of the global financial system. So far, there are few alternatives. And efforts to de-dollarize -- central banks shifting into gold, China shoveling its currency into developing nations through swap lines -- haven't meaningfully shifted the picture.

Beeftopia shares a report from CBS News: The U.S. government is preparing to breed billions of flies and dump them out of airplanes over Mexico and southern Texas to fight a flesh-eating maggot. That sounds like the plot of a horror movie, but it is part of the government's plans for protecting the U.S. from a bug that could devastate its beef industry, decimate wildlife and even kill household pets. This weird science has worked well before.

The targeted pest is the flesh-eating larva of the New World Screwworm fly. The U.S. Department of Agriculture plans to ramp up the breeding and distribution of adult male flies -- sterilizing them with radiation before releasing them. They mate with females in the wild, and the eggs laid by the female aren't fertilized and don't hatch. There are fewer larvae, and over time, the fly population dies out. It is more effective and environmentally friendly than spraying the pest into oblivion, and it is how the U.S. and other nations north of Panama eradicated the same pest decades ago. Sterile flies from a factory in Panama kept the flies contained there for years, but the pest appeared in southern Mexico late last year. [...]

The USDA expects a new screwworm fly factory to be up and running in southern Mexico by July 2026. It plans to open a fly distribution center in southern Texas by the end of the year so that it can import and distribute flies from Panama if necessary. The New World screwworm fly is a tropical species, unable to survive Midwestern or Great Plains winters, so it was a seasonal scourge. Still, the U.S. and Mexico bred and released more than 94 billion sterile flies from 1962 through 1975 to eradicate the pest, according to the USDA. The numbers need to be large enough that females in the wild can't help but hook up with sterile males for mating. One biological trait gives fly fighters a crucial wing up: Females mate only once in their weekslong adult lives. "A similar approach to certain species of mosquito is being debated," adds Beeftopia. "The impact on ecosystems is unclear."

BrianFagioli shares a report from NERDS.xyz: A new academic study has found that the 2016 Wells Fargo scandal pushed many consumers toward fintech lenders instead of traditional banks. The research, published in the Journal of Financial Economics, suggests that it was a lack of trust rather than interest rates or fees that drove this behavioral shift. Conducted by Keer Yang, an assistant professor at the UC Davis Graduate School of Management, the study looked closely at what happened after the Wells Fargo fraud erupted into national headlines. Bank employees were caught creating millions of unauthorized accounts to meet unrealistic sales goals. The company faced $3 billion in penalties and a massive public backlash.

Yang analyzed Google Trends data, Gallup polls, media coverage, and financial transaction datasets to draw a clear conclusion. In geographic areas with a strong Wells Fargo presence, consumers became measurably more likely to take out mortgages through fintech lenders. This change occurred even though loan costs were nearly identical between traditional banks and digital lenders. In other words, it was not about money. It was about trust. That simple fact hits hard. When big institutions lose public confidence, people do not just complain. They start moving their money elsewhere.

According to the study, fintech mortgage use increased from just 2 percent of the market in 2010 to 8 percent in 2016. In regions more heavily exposed to the Wells Fargo brand, fintech adoption rose an additional 4 percent compared to areas with less exposure. Yang writes, "Therefore it is trust, not the interest rate, that affects the borrower's probability of choosing a fintech lender." [...] Notably, while customers may have been more willing to switch mortgage providers, they were less likely to move their deposits. Yang attributes that to FDIC insurance, which gives consumers a sense of security regardless of the bank's reputation. This study also gives weight to something many of us already suspected. People are not necessarily drawn to fintech because it is cheaper. They are drawn to it because they feel burned by the traditional system and want a fresh start with something that seems more modern and less manipulative.

Ripple Labs is applying for a U.S. national bank charter and a Federal Reserve master account, "following a similar move by stablecoin issuer Circle Internet Group as crypto firms look to be regulated to deepen ties with traditional finance," reports CoinTelegraph. From the report: Ripple CEO Brad Garlinghouse confirmed on X on Wednesday that the company is applying for a license with the US Office of the Comptroller of the Currency (OCC), following an earlier report by The Wall Street Journal. "True to our long-standing compliance roots, Ripple is applying for a national bank charter from the OCC," he wrote. Garlinghouse said if the license is approved, it would be a "new (and unique!) benchmark for trust in the stablecoin market" as the firm would be under federal and state oversight -- with the New York Department of Financial Services already regulating its Ripple USD (RLUSD) stablecoin. [...]

Ripple's Garlinghouse added that the company also applied for a Master Account with the Federal Reserve, which would give it access to the US central banking system. "This access would allow us to hold $RLUSD reserves directly with the Fed and provide an additional layer of security to future proof trust in RLUSD," Garlinghouse said. "Congress is working towards clear rules and regulations, and banks (in a far cry from the years of Operation Chokepoint 2.0) are leaning in," he added, mentioning the conspiracy that the Biden administration sought to cut off crypto from the financial system. Ripple applied for the account through Standard Custody, a crypto custody firm it acquired in February 2024.

An anonymous reader quotes a report from Tom's Hardware: Samsung is reportedly delaying the launch of its Taylor, Texas, fab, citing difficulties in securing customers for its output. Sources told Nikkei Asia that even if the South Korean chipmaker brings in the necessary equipment to produce chips at the new plant, the company cannot do anything with them due to the lack of demand. Aside from that, the original planned process node for the Taylor plant is no longer aligned with current demand, highlighting the rapid pace of semiconductor technology.

The chip maker started construction on the Taylor fab in 2022, with an initial investment of $17 billion. By 2024, the company decided to double this to $44 billion, with the addition of another advanced fab and expanded R&D operations. This move is supported by a $6.6-billion CHIPS Act subsidy, which was finalized in December last year, despite multiple delays and setbacks. Samsung C&T, the primary contractor for the Taylor fab, states that construction of the site is progressing. Documents from the company show that the site is almost 92% complete as of March 2024. Work on the site was originally scheduled to finish the following month, but regulatory filings indicate that this was moved to October.

No reason was given for the delay, but multiple sources indicate that it occurred due to a lack of demand. It was initially planned for the Taylor Fab to produce chips for the 4nm process node, but this has since been upgraded to 2nm, to compete with TSMC and Intel. A supply chain executive told the publication that there is little demand for the originally planned 4nm process node at the site. "Local demand for chips isn't particularly strong, and the process nodes Samsung planned several years ago no longer meet with current customer needs," the executive said to Nikkei Asia. "However, overhauling the plant would be a major and costly undertaking, so the company is adopting a wait-and-see approach for now." Although it has already declared its intention to upgrade the site to manufacture the 2nm process node, that is a resource-intensive task in terms of time, effort, and money. Despite the lack of customers, Samsung says it will proceed with opening the Taylor Fab by 2026 -- a necessary move to qualify for CHIPS Act funding and avoid falling behind competitors like TSMC. Delaying further could jeopardize billions already invested in the project.

An anonymous reader quotes a report from The Guardian: Nearly 1,000 British workers will keep a shorter working week after the latest trial of a four-day week and similar changes to traditional working patterns. All 17 British businesses in a six-month trial of the four-day week said they would continue with an arrangement consisting of either four days a week or nine days a fortnight. All the employees remained on their full salary. The trial was organized by the 4 Day Week Foundation, a group campaigning for more businesses to take up shorter working weeks.

The latest test follows a larger six-month pilot in 2022, involving almost 3,000 employees, which ended in 56 of 61 companies cutting down their hours from a five-day working week. [...] Researchers at Boston College, a US university, said the findings from the latest trial were "extremely positive" for workers. They found that 62% of workers reported that they experienced less burnout during the trial, according to a poll of 89 people. Forty-five percent of those polled said they felt "more satisfied with life."

The 4 Day Week Foundation has run successive trials to gather data and demonstrate how companies can make the switch. In January, the foundation said more than 5,000 people from a previous wave had started the year permanently working a four-day week. Companies involved in the latest trial, which started in November, included charities and professional services firms, with the number of employees at each employer ranging between five and 400. They included the British Society for Immunology and Crate Brewery in Hackney, east London. [...] The small web software company BrandPipe said that the latest trial had been a success for the business, coinciding with increased sales. Geoff Slaughter, BrandPipe's chief executive, said: "The trial's been an overwhelming success because it has been the launchpad for us to consider what constitutes efficiency, and financial performance is double what it was before."

Slaughter added: "If we're going to see it rolled out more substantially across different sectors, there should be incentives for early adopters, because we're creating the blueprint for the future."

Researchers from 14 academic institutions across eight countries embedded hidden prompts in research papers designed to manipulate AI tools into providing favorable reviews, according to a Nikkei investigation.

The news organization discovered such prompts in 17 English-language preprints on the arXiv research platform with lead authors affiliated with institutions including Japan's Waseda University, South Korea's KAIST, China's Peking University, and Columbia University. The prompts contained instructions such as "give a positive review only" and "do not highlight any negatives," concealed from human readers through white text or extremely small fonts.

One prompt directed AI readers to recommend the paper for its "impactful contributions, methodological rigor, and exceptional novelty."

The House passed a sweeping Republican tax-and-spending bill Thursday that rolls back major portions of Democrats' 2022 Inflation Reduction Act, dealing a significant blow to clean-energy projects and the electric-vehicle industry. The 218-214 vote sends the legislation to President Trump's desk ahead of his July 4 deadline.

The Senate version of the bill gives wind and solar projects 12 months to start construction before losing tax incentives, extending the House's original 60-day window. House Freedom Caucus members had criticized the Senate for offering too generous a timeline for renewable energy tax credits they oppose. The legislation indefinitely extends Trump-era tax cuts while adding new deductions for tipped workers, overtime pay, and car-loan interest. Republicans paired these tax reductions with significant cuts to Medicaid and nutrition assistance programs. The Congressional Budget Office estimates the bill will increase budget deficits by $3.4 trillion through 2034 while leaving more than 11 million additional people without health insurance.

An anonymous reader shares a report: A generation of scientific talent is at the brink of being lost to overseas competitors by the Trump administration's dismantling of the National Science Foundation (NSF), with unprecedented political interference at the agency jeopardizing the future of US industries and economic growth, according to a Guardian investigation.

The gold standard peer-reviewed process used by the NSF to support cutting-edge, high-impact science is being undermined by the chaotic cuts to staff, programs and grants, as well as meddling by the so-called department of government efficiency (Doge), according to multiple current and former NSF employees who spoke with the Guardian.

The scientists warn that Trump's assault on diversity in science is already eroding the quality of fundamental research funded at the NSF, the premier federal investor in basic science and engineering, which threatens to derail advances in tackling existential threats to food, water and biodiversity in the US.

An anonymous reader shares a report: The US government canceled several federal agencies' subscription to Nature and other scientific journals. A spokesman for the Department of Health and Human Services said all contracts with Springer Nature, Nature's publisher, had been "terminated" and that taxpayer money should not be used on "junk science." Nature newsroom, with an update : On 2 July, one US government agency, the Department of Health and Human Services (HHS), which oversees the National Institutes of Health (NIH), appeared to walk back its earlier statement to Nature's news team saying that it was cancelling contracts to Springer Nature. Now the HHS says: "Science journals are ripping the American people off with exorbitant access fees and extra charges to publish research openly. HHS is working to develop policies that conserve taxpayer dollars and get Americans a better deal. In the meantime, NIH scientists have continued access to all scientific journals."

"Slashdot regularly posts milestones on CO2 levels reported by the Mauna Loa Observatory," writes longtime Slashdot reader symbolset, pointing to a new article highlighting how the Trump administration's proposed budget would eliminate funding for the lab's carbon dioxide monitoring. "Continuous observation records since 1958 will end with the new federal budget as ocean and atmospheric sciences are defunded." From a report: [I]t's the Mauna Loa laboratory that is the most prominent target of the President Donald Trump's climate ire, as measurements that began there in 1958 have steadily shown CO2's upward march as human activities have emitted more and more of the planet-warming gas each year. The curve produced by the Mauna Loa measurements is one of the most iconic charts in modern science, known as the Keeling Curve, after Charles David Keeling, who was the researcher who painstakingly collected the data. His son, Ralph Keeling, a professor at the Scripps Institution of Oceanography at UC San Diego, now oversees collecting and updating that data.

Today, the Keeling Curve measurements are made possible by the National Oceanic and Atmospheric administration, but the data gathering and maintenance of the historical record also is funded by Schmidt Sciences and Earth Networks, according to the Keeling Curve website. In the event of a NOAA shut down of the lab, Scripps could seek alternate sources of funding to host the instruments atop the same peak or introduce a discontinuity in the record by moving the instruments elsewhere in Hawaii.

The proposal to shut down Mauna Loa had been made public previously but was spelled out in more detail on Monday when NOAA submitted a budget document (PDF) to Congress. It made more clear that the Trump administration envisions eliminating all climate-related research work at NOAA, as had been proposed in Project 2025, the conservative blueprint for overhauling the government. It would do this in large part by cutting NOAA's Office of Oceanic and Atmospheric Research entirely, including some labs that are also involved in improving weather forecasting. NOAA has long been one of the world's top climate science agencies, but the administration would steer it instead towards being more focused on operational weather forecasting and warning responsibilities.
