A new laser technique targets pancreatic tumors by homing in on collagen: https://bit.ly/4q200Qn

By matching the laser wavelength to the collagen absorption peak, the method selectively ablates pancreatic ductal adenocarcinoma without harming healthy tissue. #Medicine #Health #CancerResearch

Chip-based phonon splitter brings hybrid quantum networks closer to reality: https://bit.ly/3KFOZUB

The coupler acts like a junction in a #quantum postal route to split, route or recombine single quantum vibrations to send excitations made in one processor to others on the same chip. #OPG_OpticaQ💡⚛️

This chip-based #quantum random number generator produces truly random numbers: bit.ly/48MoWVJ

The #technology both boosts weak signals and uses a second photodiode to suppress noise.

As a result, miniaturized and high-speed, it can generate unpredictable random numbers at a rate of 3 Gbps. ⚛️💡

And, if you're interested in hearing from a Nobel Laureate in Physics this year, #quantum expert David Wineland is coming to #FiO25 on 22 Oct! ⚛️💡

In 2012, he was awarded the Physics Prize for groundbreaking experimental methods to measure and manipulate individual quantum systems.

👀 Who's ready for the #NobelPrize announcements next week...?

Physics, Chemistry, Physiology/Medicine, we're ready to celebrate some of the biggest achievements in these fields.

Any ideas on hot topics for this year's prizes?

Evaporation comes from many sources, like a steaming cup of coffee, or even without heat: https://bit.ly/46iIZrQ

A study found that visible light evaporates water faster than heat alone, with photons cleaving water molecules off a hydrogel’s surface. #InternationalCoffeeDay💡

In one year, Optica Conferences and Congresses will serve more than 2,000 gallons/7,570 liters of coffee to event attendees!

We just issued the 2026 calendar of events. Download your copy and make plans to attend. (Strong cups of coffee will be ready for you.)

If you're drinking a cup of coffee on #InternationalCoffeeDay, you may notice the coffee-ring effect.💡

When a turbid drop dries on a solid surface, its suspended particulates will be deposited in a ring-like pattern, a phenomenon that may improve site-specific delivery drugs: https://bit.ly/48ax3Lw

Perovskite solar cells need caffeine too...not to get energized, but as a way to slow down the crystallization of perovskite film.

By doing so, they can arrange into a more favorable orientation for photovoltaic performance: https://bit.ly/48ai2tk

Do you smell that? 😌 ☕ It's coffee.

The coffee we serve at Optica meetings, coffee as a subject of research, coffee in your coffee, and, we hope, coffee in an Opticat mug.

Happy #InternationalCoffeeDay, where we're celebrating how a little caffeine goes a long way: https://bit.ly/4gUUZFe 💡

Unlike conventional optical tactile sensors, which tend to have a single input-output path, the sensor design achieves multiple optical channels by embedding polymer optical waveguides in silicone rubber.

The researchers tested the sensor by applying controlled pressure with a fingertip.

Researchers tested the single-pixel motion compensation technique on a 4-second video recorded at 120fps.

Seen here, the resulting output was an 8-second video sequence, still at 120fps, effectively doubling the temporal resolution by increasing the total frame count from 480 to 960. 💡⚛️
