A new way to build tiny, powerful electronics with 2D materials
- Scientists in China have developed a new technique to build small, high-performance electronic parts using 2D semiconductors.
- The method involves growing a thin layer of dielectric material on top of graphene using epitaxial growth, allowing the stack to be transferred onto other surfaces without damage.
- The research has demonstrated that the method keeps the graphene clean and maintains its excellent electrical performance.
- This breakthrough could lead to faster, smaller, and more efficient electronics, and pave the way for future advancements in the field.

Are our big appliances really dying sooner?
- Research conducted at the Norwegian University of Science and Technology (NTNU) found that the lifespan of most large household appliances has remained fairly steady since the 1950s, apart from washing machines and ovens.
- The average lifetime of a washing machine has decreased from 19.2 years to 10.6 years, a 45% decrease. Ovens have also seen a drop from 23.6 years to 14.3 years, a 39% decline.
- The decrease in the lifespan of washing machines can be attributed to increased usage, as people are doing laundry more frequently. On the other hand, ovens are often replaced during kitchen renovations, even if they are still functional.
- Efforts to increase the lifespan of appliances should consider usage patterns and people's preferences, not just longevity.

Trump's tariffs pushed me to buy a TV at Best Buy yesterday. Should you follow my lead?
- Trump's tariffs on imports could lead to higher consumer electronics prices, affecting products made in China, where most electronics are manufactured.
- Best Buy's CEO previously mentioned that Trump's tariff plans could increase prices, creating concern for potential price hikes in electronics.
- Apple could see substantial price increases if forced to manufacture devices in the US instead of China, possibly doubling or tripling current prices.
- Consumers may expect accessories and smaller electronics, particularly from Asia, to see immediate price increases due to the tariffs.
- Consumer electronics companies are likely to be impacted by the tariffs as most of their goods are produced abroad.
- Experts advise against panic buying, suggesting that consumers should only purchase if they were already planning to do so.
- Consider buying older products from 2019 to avoid potential tariff impacts on newer models.
- It is uncertain if purchasing now would offer an advantage against rising tariffs, as technology quickly becomes outdated.
- Consumers should buy electronics based on their planned purchases rather than solely as a hedge against tariffs.

This starfish-inspired wearable could track heart health on the move
- Scientists at the University of Missouri have created a new wearable device shaped like a starfish to monitor heart health, even during movement.
- The device uses five flexible arms to stay stable on the body, allowing for accurate heart readings compared to other wearables.
- Special sensors on each arm collect electrical and mechanical signals from the heart, providing a comprehensive view of heart function.
- The device is equipped with artificial intelligence to filter out movement noise and share data remotely with doctors, offering convenient at-home monitoring.
