Hello. US President Donald Trump has set the priorities for his administration in a lengthy speech to Congress. Our North America correspondent Anthony Zurcher examines its key points. Science correspondent Pallab Ghosh reports on the race to protect GPS signals from interference. And finally, we take a look at the genetically modified mice that have grown mammoth-like woolly fur. 

TOP OF THE AGENDA

Key moments from a record-long speech

The whirlwind start to his presidency was sure to offer plenty of material for Trump to cover in his address to Congress. In more than one hour and 40 minutes, the longest presidential speech to lawmakers on record, Trump set out his administration's priorities and seemed to enjoy putting the "bully" in the presidential bully pulpit, writes Anthony Zurcher. From thanking Elon Musk to the expulsion of Congressman Al Green, we've summarised the speech's key moments. Elissa Slotkin, a Senate Democrat from Michigan, gave her party's response to Trump's address, accusing the administration of sowing chaos and recklessness.

• Get the latest: Trump read a letter he received from Ukrainian President Volodymyr Zelensky during his speech to Congress, saying he "appreciated" the message.

BEYOND THE HEADLINES

Tackling the threat of GPS jamming

Russia has been accused of deploying technology to jam Global Positioning System (GPS) signals in aircraft near Nato's eastern flank. Moscow denies being behind the interference, but recent incidents have prompted a race to avoid further disruptions. Pallab Ghosh reports on the "Time Lords" working on the fiendishly difficult task of developing a new type of atomic clock.

And finally...

Mice with "mammoth-like traits" may sound like something from a horror film, but that is what a US company say they've created. Colossal Biosciences say the mice, which you can see here, are one of many steps to creating mammoth-like creatures that could one day help stop arctic permafrost from melting. Not everyone is convinced.
