A team of engineers from Gazprom transgaz Samara, led by chief engineer Pavel Gennadievich Osipov, received a patent for a system that recovers waste heat from the gas turbine drives at compressor stations. The system pairs the drive turbine with a recovery unit that runs on a reverse Brayton cycle, taking in hot exhaust gas and converting the remaining energy into electricity. Test results showed improved efficiency and power output from the drive turbine, along with a significant amount of additional electricity. The invention is among the top 100 inventions in Russia for 2021, as selected by the Federal Service for Intellectual Property. The main barrier is the cost of upgrading existing compressor stations, which have been operating for years, so operators must weigh that investment against the electricity and fuel saved over time.

- Russian Navy makes a hydrocarbon breakthrough that could shake up traditional heating technology
Scientists at the Russian Navy's Center for Science and Training (N.G. Kuznetsov Naval Academy) developed a catalytic heating device that needs no flame, which according to the patent description raises heat output and reduces fuel consumption. The invention made Russia's Top 100 inventions list five years ago. Traditional heaters waste fuel preheating cold air and their flames are hard to keep stable; this design instead converts hydrocarbons (oil, natural gas, associated gas) fully through a catalyst into carbon dioxide and water vapor inside a closed reactor, with a heat carrier taking the heat away for use. The authors say the unit starts from cold without a flame, runs automatically, and reduces harmful combustion products such as CO and soot.

- Russia Sets 4,100m Underground Record: 'Thankful' for a Century-Old Invention by a Young Soviet Engineer
Engineers from INK-Service of Irkutsk Oil Company (INK) completed a 4,100 m horizontal borehole at the Bolshetirsky field in Eastern Siberia in July 2026. The work ran 90 days and nights non-stop in geology rated 7.1 on an international difficulty scale, using automatic directional control and downhole motors. The article links the record to the turbodrill invented by Soviet engineer Matvei Kapelyushnikov, presented in 1922, which uses high-pressure drilling mud to spin the bit instead of rotating the entire steel pipe string. Pyotr Shumilov later removed the gearbox and stacked multiple turbine stages, making the device a core tool in well drilling. The technology was licensed to France's Neyrpic in 1956 and is now used by companies including Gazprom Neft, Lukoil and Tatneft.

- IMFC chair says global economy resilient; delegates walk out on Russian official
IMFC chair Mohammed Al-Jadaan said the global economy is showing 'remarkable resilience' but there is 'no room for complacency' amid wars, threats to energy and food security, high public debt and AI-related risks. Nearly half of delegates walked out when Russian Finance Minister Anton Siluanov spoke in Russian, sending a clear message to Russia, although all members agreed to the chair's statement. IMF Managing Director Kristalina Georgieva called the meetings productive but noted growing anxiety about divergence, with many lower-income countries fearing they are falling behind. The IMF and World Bank annual meetings drew more than 18,000 people to Bangkok.

- 2 High-Flying Dividend Stocks to Buy and Hold for a Decade
The article argues healthcare is rebounding in 2026, with Merck (MRK) shares up 39% and AbbVie (ABBV) up 24% year to date, versus about 12% for the S&P 500. Merck's second-quarter revenue rose 5% to $16.6 billion, beating estimates, with Keytruda sales of $8.4 billion, though Keytruda may lose patent exclusivity by 2028. AbbVie's second-quarter revenue grew 10.2% to nearly $17 billion and adjusted EPS rose 22.9% to $3.65, driven by Skyrizi and Rinvoq sales growing about 24%. AbbVie is on a streak of 54 consecutive annual dividend increases, including its time as part of Abbott Laboratories, qualifying it as a Dividend King. The author concludes both are attractive long-term holdings based on financial results, pipelines, and dividends.
- Nvidia (NVDA) Stock Price Lags Massive Earnings Growth—A Compelling Value Opportunity
Munro Partners' Munro Global Growth Fund posted a -12.6% net return in Q3 2026, trailing the MAET.ASX return of -13.8%, with long holdings the main detractors. The fund's letter named NVIDIA (NASDAQ:NVDA) its largest contributor, citing strong earnings growth and guidance for at least 70% revenue growth next fiscal year, versus consensus of 45%. Nvidia reported quarterly revenue of USD96.2bn in August, up 106% year on year, and management said growth would have been closer to 100% without supply constraints. As of October 12, 2026, NVDA closed at $214.13, down 4.23% over the past month and up 19.23% over the past year, with a $5.16 trillion market cap and a 52-week range of $164.27 to $243.37. The fund says demand for semiconductors and AI remains strong, creating a constructive setup as capex and political fears are now priced in.
- Better Artificial Intelligence Stock for 2026: C3.ai vs. SentinelOne
The article compares C3.ai, which sells enterprise AI applications, with SentinelOne, which provides AI-powered autonomous cybersecurity. In fiscal 2026 (ended April 30), C3.ai's revenue was nearly $250.3 million, down 35.7%, with a net loss of $470.4 million and negative free cash flow of $190.7 million.

The article cites C3.ai's restructuring plan from February 2026 and long government sales cycles as risks, and SentinelOne's competition from larger vendors and reliance on Amazon hosting. It says SentinelOne trades at a lower valuation relative to sales, while C3.ai has no future earnings estimates.
- Salazar Resources to Begin Drilling the Yumi Gold-Silver Veins at Tarqui, with Porphyry Drilling Planned at Monja, Ecuador
Salazar Resources closed a $3,500,000 non-brokered private placement announced on October 8, 2026, and outlined its exploration plan. Phase 1 is about 1,500 metres of drilling in five holes at the Yumi gold-silver veins on its 100%-owned Tarqui project, with drilling expected to begin in late October 2026, and the veins have not previously been drilled. Selective rock-chip samples returned 105 g/t Au and 1,038 g/t Ag, and historical BHP holes intersected porphyry-style mineralization nearby, which the company interprets as lying on the periphery of a porphyry center not yet located. Phase 2 contemplates up to about 3,500 metres of drilling in four holes at the 100%-owned Monja copper-gold porphyry target from the first quarter of 2027, subject to surface access and permits. A soil survey of about 895 samples is also planned at Quimi, part of the Tarqui-Quimi project.
- Musk: AI’s Hard Part Is “Scaling Power”: 3 Stocks Uniquely Suited to Win This New Bottleneck Trade
Microsoft said it will scale its Maia chips to multi-gigawatt deployments starting next calendar year, and Elon Musk said scaling power is the hard part of AI. The article argues power is an input that chip and app companies cannot copy quickly, which favors Vistra (VST), Constellation Energy (CEG) and GE Vernova (GEV). Vistra has lost nearly a fifth of its value over the past year even though its adjusted EBITDA rose to $5.91 billion, while Constellation's normalized EPS is expected to reach $13.29 in fiscal 2027. GE Vernova's revenue is expected to reach $60.7 billion by fiscal 2028, and Jefferies has a $298 price target on Vistra. The article warns that all three stocks could move with the mood around AI, regardless of their results.
