• Human brain weight is the mass of the adult brain, usually 1,300–1,400 grams in males and slightly lower in females. It makes up about 2% of body weight and controls all body functions.
• Females generally have 100–150 grams less brain weight than males due to natural biological differences.
• A large Swiss study found average brain weights of about 1,340 grams in males and 1,200 grams in females based on autopsy data.
• Brain weight varies with age, sex, and body structure and does not determine intelligence.
• The heaviest recorded human brain was about 2,850 grams (1899 case in the Netherlands).
• Brain weight is highest in young adulthood and slowly decreases with aging.
• Compared to other animals, the sperm whale has a much heavier brain (~7,800 grams) than humans.
• The brain uses about 20% of the body’s oxygen, making it a highly energy-demanding organ.
• Brain weight is an important factor in neurological and aging research.

A Chinese research team has developed a prototype gas-solid hydrogen battery. The team comes from the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences. The gas-solid hydrogen battery uses hydrogen-gas and metal electrodes. It enables hydrogen storage under normal temperature and pressure conditions.

The study on the gas-solid hydrogen battery was published on Wednesday in the journal Joule. Researchers present a new approach to combine hydrogen storage and electrochemical energy systems. The gas-solid hydrogen battery introduces a new direction for storage technology.

The gas-solid hydrogen battery is based on hydrogen anions as charge carriers. These hydrogen anions are essential for next-generation all-solid-state batteries. However, hydrogen anions are highly unstable under natural conditions. This instability creates a technical challenge for the gas-solid hydrogen battery system.

The research team worked for years to address conduction and construction issues. They improved hydrogen anion transport in solid environments. The gas-solid hydrogen battery prototype was created after solving these engineering problems.

The gas-solid hydrogen battery uses hydrogen gas and magnesium metal as active electrode materials. Magnesium functions in the negative electrode, while hydrogen gas supports the positive side. The system allows both hydrogen charging and electricity discharge. It also supports electricity charging and hydrogen release.

The gas-solid hydrogen battery achieves dual energy functions in one system. It enables simultaneous electrochemical energy storage and hydrogen storage. This design makes the gas-solid hydrogen battery different from conventional hydrogen systems.

Experimental results show the gas-solid hydrogen battery reached 93.9% energy utilization efficiency. This is about one-third higher than traditional thermal hydrogen storage methods. The gas-solid hydrogen battery demonstrates improved energy conversion performance.

Researchers successfully stacked multiple gas-solid hydrogen battery units. The stacked system powered an LED light bulb. This test shows practical application potential for the gas-solid hydrogen battery in real devices.

The gas-solid hydrogen battery removes the need for extreme storage conditions. It operates without high pressure or ultra-low temperatures. This simplifies hydrogen storage requirements in practical use cases.

The gas-solid hydrogen battery may support future hydrogen energy development. It offers a new technical route for hydrogen storage systems. Continued research will focus on scaling the gas-solid hydrogen battery for wider applications.

The gas-solid hydrogen battery study highlights a new direction in energy storage research. It combines hydrogen gas chemistry with solid-state battery design. The gas-solid hydrogen battery continues to attract attention in advanced energy systems.

Gold reserves remain a vital national asset. Central banks trust gold for security. As of May 2026, global reserves total about 36,020 tonnes. The top ten nations hold nearly two-thirds of this gold.

The United States leads the list. Its gold reserves stand at 8,133.46 tonnes. Italy follows with 2,451.84 tonnes. China holds 2,313.46 tonnes of gold reserves. India now ranks fourth with 880.52 tonnes.

Japan secures fifth place. Its gold reserves total 845.97 tonnes. Poland has grown its holdings rapidly. Poland’s gold reserves reach 581.64 tonnes. Turkey follows with 534.85 tonnes.

Uzbekistan holds 415.54 tonnes. Kazakhstan owns 353.59 tonnes. The United Kingdom rounds out the top ten. The UK’s gold reserves amount to 310.29 tonnes.

Data Table: Top 10 Gold Reserves (May 2026)

Why These Reserves Matter

Gold provides financial stability. Many nations diversify away from the dollar. China and India buy more gold each year. Their gold reserves grow steadily. This trend is impressive.

Emerging economies use gold as a shield. Turkey and Poland face inflation risks. Gold helps protect their currencies. The US holds its gold at Fort Knox. London remains a crucial trading hub.

Data Sources

The World Gold Council and IMF provide these figures. Official reports may lag by two months. But this data reflects May 2026 accurately.

Countries will keep buying gold. The race for reserves continues. Watch this space for updates.

 Chinese AI firm DeepSeek has announced a major DeepSeek V4-Pro price cut, reducing costs by seventy-five percent. The company confirmed the change in an official statement released on Saturday. This move permanently lowers pricing for its flagship V4-Pro artificial intelligence model.

The DeepSeek V4-Pro price cut brings API costs down significantly across all usage levels. Prices now range between 0.025 and 6 yuan per million tokens. Earlier, users were charged between 0.1 and 24 yuan per million tokens. A token represents a unit of text processed by the AI system.

The DeepSeek V4-Pro price cut comes as the company scales its infrastructure. DeepSeek did not confirm whether Huawei’s Ascend 950 chips influenced the decision. However, these chips are used to improve model performance and efficiency.

Huawei has seen rising AI chip demand due to U.S. export restrictions on advanced Nvidia semiconductors. At the same time, restrictions on chipmaking equipment continue to limit Huawei’s production capacity. These conditions shape the broader AI hardware market in China.

The DeepSeek V4-Pro price cut also reflects earlier pricing challenges. When V4 launched last month, the Pro version cost up to twelve times more than the Flash version. The company said high-end compute limits caused this pricing gap.

DeepSeek expects further adjustments once Huawei Ascend 950 supernodes are deployed in large numbers. These systems are planned for rollout in the second half of the year. Increased supply could reduce long-term computing costs.

The DeepSeek V4-Pro price cut may increase access for developers and businesses. It also intensifies competition in the global AI industry. Analysts continue to watch how pricing shifts affect market balance.

The report also raises broader questions about automation in commercial sectors. It highlights growing debate over whether AI could replace human roles in some environments.
