Research reveals exotic quantum states in double-layer graphene

-
Researchers from Brown and Columbia Universities have demonstrated previously unknown states of matter that arise in double-layer stacks of graphene, a two-dimensional nanomaterial. These new states, known as the fractional quantum Hall effect, arise from the complex interactions of electrons both within and across graphene layers.

5 investors discuss what’s in store for venture debt following SVB’s collapse

-
There are many questions around the implications of Silicon Valley Bank’s (SVB) collapse that won’t be answered for a long time. But there’s one question that many startups and investors are hoping will get answered sooner rather than later: What happens to venture debt? SVB was one of the larger, if not the largest, providers of venture debt to U.S.-based startups. And now that First Republic Bank has also gone under, that question has spiraled, growing ever more complex. Many startups rely on venture debt: it’s both a cheaper alternative to raising equity and can serve as a capital tool that helps companies build in ways that equity isn’t great for. For some companies in capital-intensive areas like climate, fintech and defense, access to debt is often the only avenue to growth or scale. Thankfully, venture capitalists aren’t too worried about the SVB collapse’s impact on venture debt as a whole. We’re widening our lens, looking for more investors to participate in TechCrunch su...

GAIA Design has raised more capital to become the West Elm of Mexico

-
Designing higher end furniture for Mexico’s rising middle and upper-middle class consumers has netted the Mexico City-based GAIA $15 million in a new round of funding. The bridge round will take the company through to a much larger capital raise planned for 2021 as the company capitalizes on the growth of e-commerce in Mexico. A 2019 report from JP Morgan put the e-commerce market in Mexico at around $22.6 billion, and that’s with online sales only accounting for just 1.7% of the overall retail market. JP Morgan expects the market to increase at a 12.6% growth rate annually. As with everything else, the COVID-19 pandemic has accelerated the adoption of digital services as the country’s population looks to practice safe social distancing and reduce the spread of the virus. For those consumers who can afford to shop online — even for high value products like furniture — they are, according to GAIA chief executive Philippe Cahuzac. At GAIA the new funding will be used to add new f...

Welcome back to This Week in Apps, the weekly TechCrunch series that recaps the latest in mobile OS news, mobile applications and the overall app economy. The app industry continues to grow, with a record number of downloads and consumer spending across both the iOS and Google Play stores combined in 2021, according to the latest year-end reports . App Annie says global spending across iOS, Google Play and third-party Android app stores in China grew 19% in 2021 to reach $170 billion. Downloads of apps also grew by 5%, reaching 230 billion in 2021, and mobile ad spend grew 23% year-over-year to reach $295 billion. In addition, consumers are spending more time in apps than ever before — even topping the time they spend watching TV, in some cases. The average American watches 3.1 hours of TV per day, for example, but in 2021, they spent 4.1 hours on their mobile device. And they’re not even the world’s heaviest mobile users. In markets like Brazil, Indonesia and South Korea, users ...
