This year has seen remarkable developments in artificial intelligence, an inflection point for quantum computing, progress in aging research, a number of exciting discoveries in astronomy, a potentially revolutionary new material, and many more breakthroughs.
These were our top 20 most viewed blogs of 2022, in reverse order. See you in 2023!
The year 2023 is set to be revolutionary for technology, with many disruptive trends expected to reshape how businesses function and how people interact with each other. From metaverse-based virtual workspaces, advancements in quantum computing and green energy sources to innovations in robots and satellite connectivity – here’s a look at the technological trends that could define the coming year.
According to BCG’s “Mind the Tech Gap” survey, a majority of businesses across 13 countries plan to increase their spending on digital transformation in 2023 vs. 2022. The top two areas for future investments are business model transformation and sustainability, with respondents expressing concern over the uncertain return on investment from digital transformation initiatives. Furthermore, Sylvain Duranton, a Senior Partner & Managing Director at Boston Consulting Group, Global Leader of BCG X states that “Despite economic headwinds, 60% of BCG’s recently surveyed companies plan to increase their investments in digital and AI in 2023. But many of those surveyed simultaneously expressed concern over the uncertainty of the ROI from digital transformation. During covid, we saw companies that used advanced digital technologies and AI outperform their counterparts.
As part of Conversations on the Quantum World, a webinar series hosted by the Caltech Science Exchange, Professor of Theoretical Physics Kathryn Zurek and Professor of Physics Rana Adhikari talk about one of the biggest mysteries in physics today: quantum gravity.
Quantum gravity refers to a set of theories attempting to unify the microscopic world of quantum physics with the macroscopic world of gravity and space itself. Zurek, a theorist, and Adhikari, an experimentalist, have teamed up with others to design a new tabletop-size experiment with the potential to detect signatures of quantum gravity.

Community Detection in Brain Connectome using Quantum Annealer Devices:
A wild theory suggests that consciousness may explain quantum mechanics, by forcing the subatomic particles to choose one concrete outcome.
There could be variables beyond the ones we’ve identified and know how to measure. But they can’t get rid of quantum weirdness.
Experts are warning that quantum computers could eventually overpower conventional encryption methods, a potentially dangerous fate for humanity that they’re evocatively dubbing the “quantum apocalypse,” the BBC reports.
Cracking today’s toughest encryption would take virtually forever today — but with the advent of quantum computers, they’re warning, the process could be cut down to mere seconds.
And that kind of number-crunching power could have disastrous consequences if it were to land in the wrong hands.
Lasers have been used to throw and catch extremely cold, single atoms. The technique could be used to assemble quantum computers in the future.
Ordinarily, to measure an object we must interact with it in some way. Whether it’s by a prod or a poke, an echo of sound waves, or a shower of light, it’s near impossible to look without touching.
In the world of quantum physics, there are some exceptions to this rule.
Researchers from Aalto University in Finland propose a way to ‘see’ a microwave pulse without the absorption and re-emission of any light waves. It’s an example of a special interaction-free measurement, where something is observed without being rattled by a mediating particle.
