In today’s interconnected world, infectious diseases pose an escalating threat, as demonstrated by the coronavirus pandemic and outbreaks of H1N1, SARS, Ebola, Zika, and H5N1 (bird flu) viruses—all of which have had significant global health and economic impacts.
But more common viral diseases also contribute to global health challenges and economic costs. For example, seasonal influenza epidemics occur annually, causing a substantial global disease burden and economic losses exceeding $11.2 billion each year in the United States alone. Meanwhile, herpes simplex virus-1 (HSV-1), spread primarily through oral contact, infects over two-thirds of the global population and is the leading cause of infectious blindness in Western countries.
Low vaccination rates for influenza viruses and the lack of an HSV vaccine underscore the need for a new approach—one that targets reducing viral loads at the sites where transmission occurs. And for viruses like these, which are transmitted more efficiently through the mouth than the nose, this means focusing on the oral cavity.
Andreessen Horowitz’s Anjney Midha argues that the US has no choice in terms of how it approaches the artificial intelligence race with China: “We must win.”
Speaking with Semafor’s Reed Albergotti at Semafor’s World Economy Summit on Wednesday, Midha, who is a general partner at the Silicon Valley venture capital firm, said that US AI companies should double down on driving growth rather than stifle innovation over concerns of potentially harmful use cases. People all over the world will choose to use American AI tools, so long as they’re the best available.
“This is why a billion people in India still use WhatsApp. It was invented in Silicon Valley,” Midha said.
Catalytic conversion of waste CO2 into value-added fuels and chemicals offers unprecedented opportunities for both environmental protection and economic development. Electrocatalytic CO2 reduction reaction (CO2RR) has garnered significant attention for its ability to efficiently convert CO2 into clean chemical energy under mild conditions. However, the relatively high energy barrier for *COOH intermediate formation often becomes the determining step in CO2RR, significantly limiting reaction efficiency.
Inspired by enzyme catalysis, a team led by Prof. Jiang Hai-Long and Prof. Jiao Long from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) developed a novel strategy to stabilize *COOH intermediate and enhance electrochemical CO2 reduction by constructing and modulating the hydrogen-bonding microenvironment around catalytic sites. Their work is published in the Proceedings of the National Academy of Sciences.
In this work, the team co-grafted catalytically active Co(salen) units and proximal pyridyl-substituted alkyl carboxylic acids (X-PyCn) onto Hf-based MOF nanosheets (MOFNs) via a post decoration route, affording Co&X-PyCn/MOFNs (X = o, m or p representing the ortho-, meta-, or para-position of pyridine N relative to alkyl chain; n = 1 or 3 representing the carbon atom number of alkyl chains) materials.
Questions to inspire discussion.
🚕 Q: What’s the expected price range for Tesla’s upcoming Robo Taxi? A: Tesla’s Robo Taxi will enter a new price tier under $30,000, significantly increasing sales and profitability due to its lower hardware cost structure.
Tesla’s Expansion in China.
🇨🇳 Q: How is Tesla expanding its Full Self-Driving (FSD) in China? A: Tesla is offering a 30-day free trial of FSD in China, with new software version 13.2.8 for both Hardware 3 and 4, likely rolling out between end of April and early May.
🤝 Q: Why is Tesla’s relationship with China important? A: Tesla’s good relationship with China, established 5 years ago without a joint venture, is crucial for success as China benefits from learning Tesla’s FSD perspective and benchmarking against their own vehicles.
💰 Q: How will tariffs affect low-priced vehicles in the US? A: 25% tariffs on imported vehicles will apply to nearly 80% of vehicles priced under $30,000, impacting popular models like Civic and Corolla.
! Elon Musk seems to think that the Tesla Bot will take over many of the boring, repetitive, and dangerous jobs that are fundamental to our economy. Elon believes the Tesla Bot will eventually take over the Tesla vehicles as the company’s primary source of revenue…
The field-reversal configuration (FRC) represents a fusion device concept capable of high power density with a compact geometry. Here, the authors report on the generation and sustainment of a FRC by means of neutral beam injection in the C-2W machine at TAE technologies. This contributes towards establishing FRC as an alternative economic fusion device.
