To combine two low-energy photons into one high-energy photon efficiently, the energy must be able to hop freely, but not too quickly, between randomly oriented molecules of a solid. This Kobe University discovery provides a much-needed design guideline for developing materials for more efficient PV cells, displays, or even anti-cancer therapies.

Light of different colors has different energies and is therefore useful for very different things. For the development of more efficient PV cells, OLED displays, or anti-cancer therapies, it is desirable to be able to upcycle two low-energy photons into a high-energy photon, and many researchers worldwide are working on materials for this up-conversion.

During this process, light is absorbed by the material, and its energy is handed around among the material’s molecules as a so-called “triplet exciton.” However, it was unclear what allows two triplet excitons to efficiently combine their energies into a different excited state of a single molecule that then emits a high-energy photon, and this knowledge gap has been a serious bottleneck in the development of such materials.

A critical molecule for the metabolism of living organisms has been synthesized for the first time by University of Hawaiʻi at Mānoa researchers at low temperatures (10 K) on ice coated nanoparticles mimicking conditions in deep space, marking a “cool” step in advancing our understanding of the origins of life.

We know that there are thousands of exoplanets out there, with many millions more waiting to be discovered. But the vast majority of exoplanets are simply uninhabitable. For the few that may be habitable, we can only determine if they are by examining their atmospheres. LIFE, the Large Interferometer for Exoplanets, can help.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have demonstrated that advanced quantum-based cybersecurity can be realized in a deployed fiber link.

Researchers at ETH have managed to trap ions using static electric and magnetic fields and to perform quantum operations on them. In the future, such traps could be used to realize quantum computers with far more quantum bits than have been possible up to now.

LG Electronics may no longer be a household name in smartphones, but it still sees a big future in gadgets like robots. Today, the company confirmed a $60 million investment in Bear Robotics, the California startup that makes artificial intelligence–powered server robots (autonomous tray towers on wheels that are meant to replace waiters) for restaurants and other venues. With the investment, LG Electronics becomes Bear’s largest shareholder.

Bear’s last fundraise in 2022 valued the company at just over $490 million post-money, per PitchBook data. It’s not clear what the valuation is for this latest investment, but the last year has not been a great one for startups in the space.

On the other hand, the current vogue for all things AI, and the general advances that are coming with that, are giving robotics players a fillip — see yesterday’s Covariant news, for another example. Still, it’s not clear what Bear hopes to tackle next with the basic trays-on-wheels form factor that it has adopted for its flagship Servi robots.

Researchers have found a way to stop active cancer cells in their tracks – meaning they can then be eliminated by new drug treatments.

A collaborative research project between the University of Dundee’s Drug Discovery Unit (DDU) and Queen Mary University of London, has identified chemical compounds, called tool molecules, that can halt active cancer cells.

A 78-year-old man who had been living inside an iron lung since surviving polio in the 1950s has passed away.

As CBS News reports, Paul “Polio Paul” Alexander garnered a huge following on social media, getting millions of views on TikTok as he answered questions about his unusual life.

The medical device didn’t stop Alexander from becoming a lawyer and opening his own successful practice. He also published a book about his life.

Electronic states that resemble molecules and are promising for use in future quantum computers have been created in superconducting circuits by physicists at RIKEN.
