Chinese scientists, publishing in Nature Communications, identified 11,742 virus types in 60 sediment samples from the Clarion-Clipperton zone, of which 11,662 (over 99%) had never been recorded before. The deep-sea area, by some estimates, holds over 27 billion tons of polymetallic nodules rich in nickel, cobalt and manganese, and the International Seabed Authority has granted 17 exploration contracts there, 5 of them held by Chinese organizations. The researchers said only about 4% of protein clusters from these viruses share common ground with existing data from the ocean, deep trenches and hydrothermal environments. The region’s heavy metal-rich but nutrient-poor conditions may have driven distinctive traits in these viruses, most of which belong to the class Caudoviricetes and generally pose no danger to humans. The team says deep-sea mining could alter the role of viruses in nutrient cycling, so its environmental impact may be more complex than simply changing the seafloor’s terrain.

- Chinese Ship Carrying Nearly 1,000 Tonnes of “Unusual Cargo” Quietly Moves at Sea, Barely Using Oil and Emitting No Exhaust
The bulk carrier Mineral Europa, with a deadweight of about 210,000 DWT, is certified to carry nearly 1,000 tonnes of green ammonia to Australia after receiving fuel offshore at Zhoushan on October 13. It marks the first commercial-scale ship-to-ship green ammonia bunkering, coordinated by CEEC Hydrogen Energy, Belgium's CMB.TECH and Jiangsu Andefu Energy Technology, with fuel transferred from the Shenghang Yongle. The ammonia was produced at CEEC's Songyuan hydrogen park, some 2,000 km from Zhoushan, and trucked around 700 km before loading. The article notes ammonia's energy density is about 2.4 times lower than marine diesel, and current engines still need roughly 5% of their energy from diesel as a pilot fuel. A Norwegian report projects ammonia could supply about 25% of shipping energy demand by 2050, though experts say it is too early to treat it as a complete solution.
- Vietnam's Neighbor Is Stockpiling Gold at an Unprecedented Pace: Over 1,000 Tonnes Imported in 8 Months, Reserves Near 2,400 Tonnes
The People's Bank of China (PBOC) bought about 23 tonnes of gold in September 2026, its largest monthly purchase in nearly 3 years and the 23rd consecutive month of reserve increases. In the first 8 months of 2026, China spent a record $158.8 billion to import over 1,000 tonnes of gold, far above $96.5 billion and 886 tonnes for all of 2025, even as world gold prices fell more than 8% in September to about $4,176 an ounce. According to analysts, the PBOC aims to reduce reliance on the US dollar and US Treasuries, as China's US Treasury holdings dropped to $618 billion in July, the lowest in 18 years. One estimate puts PBOC purchases at about 190 tonnes from January through August, including 110 tonnes not officially disclosed. The WGC says China held about 2,387 tonnes of gold as of August 2026, but demand could cool if China's property and stock markets recover.
- U . S . Machinery , Metals and Chip Production Climb as Manufacturing Expands
U.S. manufacturing output rose 0.3% in September, according to the Federal Reserve, reversing a revised 0.2% decline in August, despite a 3.0% drop in motor vehicle production. Machinery output increased 1.4% for the month, primary metals rose 1.6%, and electrical equipment climbed 1.3%, while semiconductor production jumped 2.1% and was 19.9% above a year earlier. Total manufacturing grew at a 0.7% annual rate in the third quarter, slowing from 5.6% in the second quarter. Regional surveys also pointed to expansion: the New York Fed’s general business conditions index jumped to 25.5 from 7.6, the highest since December 2021, and the Philadelphia Fed’s index stayed positive at 20.9. Both surveys reported persistent price pressures, and more than 52% of Philadelphia Fed survey respondents planned to increase capital spending in 2027.
- Discovery of Nearly 5,000-Year-Old Shipwreck with 'Treasure' Under Seabed
Archaeologists have found a shipwreck believed to be the oldest in the world at a depth of 30 meters near Kekova island, off Turkey's southern coast. The 9.75-meter vessel sank an estimated 4,400 to 4,700 years ago; its wooden hull has decayed, but ceramic jars and stone anchors survive. Clay analysis shows the jars were made in workshops in the Jordan Valley, hundreds of miles away, and similar jars have been found near the Giza, Saqqara and Abusir pyramids, as well as at Troy and Crete. An unusual pottery vessel with nine different symbols and two holes may have been used to churn milk into cheese or butter, suggesting sailors may have carried live goats aboard. The excavation began in 2026, led by the Antalya Museum Directorate under the scientific supervision of Professor Hakan Öniz of Akdeniz University.
- 19-Year-Old Skips College, Sells Hundreds of Orders a Day and Earns VND 21 Billion From One Product
Mike Satterlee, who had just graduated from high school in the US, was selling hundreds of orders a day for CruiseCup's two-can insulated holder after an Instagram post in August 2025. He had 60 3D printers at his facility in New York and estimated it would take about 6 weeks to fill all orders. According to financial documents reviewed by CNBC Make It, CruiseCup generated about $808,000 in gross revenue in 2025 (over VND 21 billion) through its website and TikTok Shop. Before this, he ran Solefully, which he estimated brought in about $250,000 in 2024, and chose not to attend university to focus on the business. CruiseCup now operates 160 3D printers, and he keeps only about $500-1,500 a month because most profit is reinvested.

- Amazon (AMZN) Stock Costs $250 a Share. Here's Why I'd Still Buy It.
The article argues that Amazon, trading at about $250 a share, is still worth buying for the author, who would buy it if he did not already own it. The main reason is that the stock looks appealingly valued: its forward P/E of about 24 is well below its five-year average of 39, while its price-to-sales ratio of 3.6 is slightly above the five-year average of 3. Amazon ranked fourth in the 2026 Kantar BrandZ Global Top 100, with a brand value of $1 trillion, and its shares have averaged annual gains of 22% over the past 15 years. The author stresses that a stock's absolute price means little on its own, so investors should compare it with earnings and sales and research each company in depth.
- Amazon Just Made Its AI Chips Easier to Use. Should Nvidia Investors Be Worried?
Amazon announced TorchNeuron, a free open-source tool that lets developers run existing PyTorch code on its Trainium chips with minimal changes, with a public beta due on Oct. 20. This challenges a key part of Nvidia's moat, because switching away from CUDA typically carries large costs in time and labor. However, the tool only covers PyTorch work, custom CUDA code will not port easily, and the release is still in beta, with the ease-of-switching claims coming from Amazon itself. Google is also developing a similar tool, TorchTPU. The author sees it as a chink in Nvidia's narrative and does not expect a major near-term effect on order flow or pricing power, but says the market may no longer pay quite the same premium for Nvidia stock.
- Cisco Systems (CSCO) Unveiled 102.4T AI Networking Platforms
Cisco Systems unveiled new AI networking platforms built on Silicon One P200, G300 and G302 switching chips, with 51.2T and 102.4T systems. It also introduced 1.6T optical modules and integrated liquid cooling aimed at high-density AI data centers, and disclosed a collaboration with NVIDIA, TE Connectivity and Amphenol to co-develop a 400Gb/s per lane USFP optical module and open specification. The company has a market cap of US$423.4b. The article says the launch supports Cisco's position as an AI networking provider competing with Arista and Juniper, but the richer hardware mix adds to margin pressure that has already contributed to non-GAAP gross margin compression.
