Exciting breakthrough technology from the lab, now live in @CellCellPress ! Instead of cutting the genome where proteins bind (e.g., Cut&Tag), D&D-seq scars the DNA with a deaminase, allowing single cell genome mapping of TFs and chromatin remodellers!

Kde se vlastně vzaly "peptidy na hubnutí"? Téměř dobrodružný příběh ve vlákně ukazuje, že nešlo o jeden nahodilý objev, ale dlouholeté úsilí mnoha vědců z různých "neužitečných“ oblastí základního výzkumu.

Tonight, the Russians struck Kyiv and other Ukrainian cities and communities. The largest number of missiles was directed at the capital – at ordinary residential buildings, at schools; they burned down a food market, one of Kyiv’s oldest markets. The Russian strike effectively destroyed the Chornobyl Museum, damaged the National Art Museum and the building housing the office of Germany’s ARD. As of now, 69 people have been reported injured in the capital. Tragically, two people were killed in this senseless Russian attack. My condolences to everyone who has lost family members and loved ones.

I have already spoken with the President of France and the Prime Minister of Norway. There will be further communication with our partners today. I am grateful to everyone who is not staying silent about what Russia is doing. They are waging war solely against our people – against our memory, our history, and everything that makes up normal human life. It is important that Russia understands that they will be held accountable for all these crimes.

Look at this map. Each yellow dot is a russian strike on Ukraine since 2025.

Over 30,000 aerial targets in under five months.

No other country on Earth would be allowed to do this.

russia is committing state terrorism in plain sight. The world’s silence is complicity.

Jedno z nejostudnějších hlasování sněmovny v její historii od roku 1993. A že je s čím soutěžit.

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

A rescue operation is currently underway in Kyiv at the site of a Russian drone strike on a nine-story residential building – an entire section of the building has been completely destroyed. Dozens of people have been rescued. Tragically, one person has been killed. My condolences to their family and loved ones. People may still be trapped under the rubble.

Overnight, the Russians launched more than 670 attack drones and 56 missiles against Ukraine. Ballistic, aeroballistic, and cruise missiles were used in the strikes. The main target of this attack was Kyiv. There is damage at twenty locations across the city – ordinary residential buildings, a school, a veterinary clinic, and other purely civilian infrastructure. Destruction has also been reported in the Kyiv region, while similar terrorist strikes targeted energy infrastructure in Kremenchuk, as well as port and residential areas in Chornomorsk.

In total, since midnight yesterday, Russia has used more than 1,560 drones against our cities and communities. These are definitely not the actions of those who believe the war is coming to an end. It is important that partners do not remain silent about this strike. And it is equally important to continue supporting the protection of our skies. The PURL initiative is needed so that Ukraine can defend itself against ballistic strikes like these. And likewise, in the interests of everyone seeking peace, pressure on Russia must continue. I thank everyone who stands with Ukraine.

[Defense of Ukraine @DefenceU]

One of the largest air attacks of the full-scale war came right after the so-called “parade ceasefire.”
Another reminder: Russia does not seek peace. Russia must be forced into peace.
