Fighting between government forces and Houthi fighters has intensified across multiple fronts in Yemen amid a spiralling humanitarian crisis. Eight soldiers loyal to the internationally recognised Yemeni government were killed during heavy clashes on the al-Maqatirah front in Lahij governorate, the government-affiliated Tur al-Bahah military axis said in a statement on Saturday. Elsewhere in Taiz, government forces said they broke a Houthi attack on the al-Shaqab front, while government-aligned Homeland Shield Forces reported destroying a Houthi supply vehicle with a drone in al-Wazziyah. The Southern Giants Brigades also said they targeted Houthi positions with precision strikes in al-Madaribah, near the Lahij border. Meanwhile, government troops and allied Popular Resistance fighters pressed ahead with their offensive in al-Jawf and Marib. Military officials reported using artillery barrages and drone strikes against Houthi military positions, barracks and troop assemblies in al-Jawf, while coalition aircraft bombed Houthi command hubs and supply depots.

Plus: Ukraine says sudden Starlink speed limits disrupted key drone missions. Pig kidneys that were "frozen" for a year have been brought back to life Pig kidneys that were cooled to -150 C and stored in a freezer for months have been successfully rewarmed and shown to work again for the first time, say scientists. The kidneys, which are similar in size to human ones, were left in a glass-like state, in one case for over a year. Once they had been rewarmed, tested in machines, and transplanted into pigs, the kidneys regained their color and made urine--key signs they were working. The results are a big milestone. But the team still needs to establish whether the approach could work for humans.
