Celebrating the birthday of William Morris, born on this day in 1834. He played a central role in the Arts and Crafts Movement, championing the value of handmade craftsmanship at a time when the Victorian era was defined by industrial progress.

🧡Scientists from @physics_UW and partners have trapped infrared light in a layer just 40 nm thick using MoSe₂! This breakthrough could accelerate the future of photonics. he results were published in the prestigious journal “ACS Nano”

I will have the pleasure to give a lecture for Koło Naukowe Optyki i Fotoniki UW - Optica SPIE EPS IEEE Student Chapter at the Faculty of Physics UW. Just tomorrow!

Fresh off the press - first step towards Majorana based qubits on artificial Kitaev chain. Check out our scalable readout method! More to come, soon from UCSB! https://t.co/vqOGU5A7mD

New samples with II-VI quantum emitters for my @NCN_PL project devoted to subwavelength gratings have been grown at @MBEatUW. Some of them provide a strong photoluminescence signal even at room temperature!

Scientists have discovered that ants, after collecting grains and seeds which they need to store for the winter, actually break them into halves before storing in their nests. This is because by breaking the seeds into half, it stops them from germinating despite the most perfect conditions.

But here comes the even more interesting part.

Scientists were stunned when they discovered that coriander seeds stored in the ant nest were always broken down into 4 pieces instead of 2 pieces.

After some lab research, scientists discovered that a coriander seed is the only seed that can germinate even after being divided into two, but can not germinate after it’s divided into four parts.

Sergei Lavrov just went on NBC to say the Donbas is russian. I just went to Donetsk & spoke to soldiers who said the opposite. They are fighting every day to defend their land & for freedom. Don’t listen to russian propaganda 🫡

The Future is Quantum! Today, I’m at the University of Gdańsk @Uniwersytet_GD at the Quantum Conference where during the debate “Buy off-the-shelf vs. Build in-house. Quantum Technological Independence” I postulate we must invest more in developing quantum research in Poland!

Did you know that already more than 1000 glaciers have disappeared in Switzerland over the last 50 years as a consequence of human-caused climate change?

One of those is Pizolgletscher which I visited today. Always a saddening yet impressive sight...

Historic heatwave for France.

Many stations are expected to break their all time records today with temperatures likely peaking around 44, maybe 45°C.

Red heat warnings have been issued.

[Met4Cast - UK Weather @Met4CastUK]

Astonishing levels of heat expected in France on Monday with temperatures possibly reaching 44/45°C.

To be clear - This is NOT “normal” summer hot weather. The first time France exceeded 45°C was in 2019.

This heat can be dangerous even for healthy / fit people.

We are turning Earth into a unlivable Hot House Earth
Earth was about 2.65 degrees Fahrenheit (or about 1.47 degrees Celsius) warmer in 2024 than in the late 19th-century (1850-1900) preindustrial average.

The 10 most recent years are the warmest on record.https://t.co/zTyT84eBQA

When temperatures reach around 49C to 50C, plants & Forest seem to self combust.

A project "Electrically powered compact single photon sources" has just been launched! It is carried out jointly by the Faculty of Physics at UW @physics_UW, the Institute of Physics at @p_lodz_pl, and the Institute of High Pressure Physics PAS. More at: https://t.co/RVj0S5cWg2
