The Wall Street Journal created dozens of automated accounts that watched hundreds of thousands of videos to reveal how the social network knows you so well A Wall Street Journal investigation found that TikTok only needs one important piece of information to figure out what you want: the amount of time you linger over a piece of content. Every second you hesitate or rewatch, the app is tracking you. Photo illustration: Laura Kammermann/The Wall Street Journal
The bridge, which was fabricated from stainless steel rods by six-axis robotic arms equipped with welding gear, spans the Oudezijds Achterburgwal in Amsterdam’s Red Light District.
A year ago, we estimated that up to $250 billion of US healthcare spend could potentially be shifted to virtual or virtually enabled care. Approaching this potential level of virtual health is not a foregone conclusion. It would likely require sustained consumer and clinician adoption and accelerated redesign of care pathways to incorporate virtual modalities.
- Telehealth utilization has stabilized at levels 38X higher than before the pandemic. After an initial spike to more than 32 percent of office and outpatient visits occurring via telehealth in April 2020, utilization levels have largely stabilized, ranging from 13 to 17 percent across all specialties.2 This utilization reflects more than two-thirds of what we anticipated as visits that could be virtualized.3
- Similarly, consumer and provider attitudes toward telehealth have improved since the pre-COVID-19 era. Perceptions and usage have dropped slightly since the peak in spring 2020. Some barriers—such as perceptions of technology security—remain to be addressed to sustain consumer and provider virtual health adoption, and models are likely to evolve to optimize hybrid virtual and in-person care delivery.
- Some regulatory changes that facilitated expanded use of telehealth have been made permanent, for example, the Centers for Medicare & Medicaid Services’ expansion of reimbursable telehealth codes for the 2021 physician fee schedule. But uncertainty still exists as to the fate of other services that may lose their waiver status when the public health emergency ends.
- Investment in virtual care and digital health more broadly has skyrocketed, fueling further innovation, with 3X the level of venture capitalist digital health investment in 2020 than it had in 2017.4
- Virtual healthcare models and business models are evolving and proliferating, moving from purely “virtual urgent care” to a range of services enabling longitudinal virtual care, integration of telehealth with other virtual health solutions, and hybrid virtual/in-person care models, with the potential to improve consumer experience/convenience, access, outcomes, and affordability.

How close have you ever gotten to a wild bird? Can you remember the details of its plumage or the curvature of its beak? Did it sit in one place long enough for you to really study all of its colors and other characteristics? Probably not—at least if it was alive. The avid birders among us sometimes search their whole life for a glimpse of a particularly rare species. But if you are just a casual observer of the winged creatures around us, the ones you do see likely come and go as flashes of color and sound. For ornithologists, the elusive nature of birds is just part of the job. Beyond fieldwork, though, access to rare or extinct species or those with a limited range can be especially difficult to get. If you were, say, hoping to study the green-headed tanager (a riotously multicolored songbird native to South America) and unable to travel to the northeastern region of the continent where it can be found, you would have to ask a museum to send you a specimen in the mail. Access to rare specimens, such as those of extinct birds, can be especially difficult to get.
The EU has been working for months on a joint digital travel #certificate for those vaccinated, freshly tested, or recently recovered from the virus. The free certificates, which will contain a QR code with advanced security features, will allow people to move between #European countries without having to quarantine or undergo extra coronavirus tests upon arrival. The pass is already available in France.
