Questions to inspire discussion.
📊 Q: How often do these extreme job offers occur in the tech industry? A: These hundred-million-dollar job offers are rare occurrences and not representative of typical hiring practices in the tech industry, even during boom cycles.
🔄 Q: What does Meta’s hiring freeze suggest about the AI industry? A: Meta’s sudden shift from aggressive hiring to a freeze may indicate a potential cooling in the AI sector or a strategic reassessment of their AI investments and talent needs.
Strategic Considerations for Companies.
🏢 Q: Why are big tech companies making such large offers for AI talent? A: Large tech companies are making enormous offers to secure top AI talent due to perceived strategic vulnerability and the fear of falling behind in a rapidly evolving technological landscape.
🔍 Q: What should companies consider when competing for AI talent? A: Companies should evaluate the long-term sustainability of offering extreme compensation packages and consider the potential market shifts that could affect the value of AI talent investments.
Some 390 million years ago in the ancient ocean, marine animals began colonizing depths previously uninhabited. New research indicates this underwater migration occurred in response to a permanent increase in deep-ocean oxygen, driven by the above-ground spread of woody plants—precursors to Earth’s first forests.
That rise in oxygen coincided with a period of remarkable diversification among fish with jaws—the ancestors of most vertebrates alive today. The finding suggests that oxygenation might have shaped evolutionary patterns among prehistoric species.
The study is published in the journal Proceedings of the National Academy of Sciences.
A research team from the University of Basel, Switzerland, has developed a new molecule modeled on plant photosynthesis: under the influence of light, it stores two positive and two negative charges at the same time. The aim is to convert sunlight into carbon-neutral fuels.
Plants use the energy of sunlight to convert CO2 into energy-rich sugar molecules. This process is called photosynthesis and is the foundation of virtually all life: animals and humans can “burn” the carbohydrates produced in this way again and use the energy stored within them. This once more produces carbon dioxide, closing the cycle.
This model could also be the key to environmentally friendly fuels, as researchers are working on imitating natural photosynthesis and using sunlight to produce high-energy compounds: solar fuels such as hydrogen, methanol and synthetic gasoline. If burned, they would produce only as much carbon dioxide as was needed to produce the fuels. In other words, they would be carbon-neutral.
Chemical engineers at EPFL have developed a new approach to artificial photosynthesis, a method for harvesting solar energy that produces hydrogen as a clean fuel from water.
“Artificial photosynthesis is the holy grail of all chemists,” says Astrid Olaya, a chemical engineer at EPFL’s Institute of Chemical Sciences and Engineering (ISIC). “The goal is to capture sunlight, on the one hand to oxidize water to generate oxygen and protons, and on the other to reduce either protons to hydrogen or CO2 to chemicals and fuels. This is the essence of a circular chemical industry.”
With global energy demands increasing, we are in need of viable alternatives to fossil fuels, whose negative environmental impact has also become all too apparent. One of those alternatives is hydrogen, which can be consumed in simple fuel cells for energy, leaving behind only water.

Powered by solar cells and optical signals, new autonomous smartlets fold into cubes, sense stimuli, and coordinate in aquatic environments.
MIT’s 1972 global collapse warning revisited: Humanity enters make-or-break decade.
Nearly five decades later, sustainability analyst Gaya Herrington revisited World3 with fresh data. Her study, published in the Journal of Industrial Ecology in November 2020 and later shared by KPMG (where she then worked), compared several of the model’s scenarios with decades of empirical trends across variables such as population, fertility and mortality, industrial output, food production, services, non-renewable resources, persistent pollution, human welfare, and ecological footprint.
The aim was straightforward. After half a century, which of World3’s possible futures does the real world most resemble? Herrington found that the dynamics described in 1972 still fit the data “strikingly” well. In scenarios that keep growth as the primary goal, what the original authors called the “standard run” and what we’d now call “business as usual,” the model points to declines in industrial capital, agricultural output, and welfare within this century.
Compared with the energy-intensive Haber-Bosch process, renewable energy-driven electrocatalytic nitrate reduction reaction (NO3−RR) provides a low-carbon route for ammonia synthesis under mild conditions. Using nitrate from wastewater as the nitrogen source and water as the hydrogen source, this route has the potential to produce ammonia sustainably while mitigating water pollution.
Copper (Cu)-based catalysts show a good performance for NO3−RR to ammonia. However, they suffer from issues including high overpotential, competing nitrite (NO2–) formation, and low overall energy efficiency.
In a study published in ACS Catalysis, a team led by Prof. Bao Xinhe and Prof. Gao Dunfeng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences, along with Prof. Wang Guoxiong from Fudan University, proposed hydroxyl (*OH) adsorption as a selectivity descriptor for ammonia synthesis via NO3−RR over Cu catalysts.
