After a second day of peace talks in Geneva, the Syrian government delegation has agreed that women and children may leave the besieged centre of the city of Homs, but said that a list of names would be needed of men who want to leave. Syrian deputy Foreign Minister Faisal Mekdad also said the government would let an aid convoy into the city. The United Nations mediator on the Syrian conflict Lakhdar Brahimi welcomed the moves as the first tangible outcome of the talks. Here's Bridget Kendall in Geneva.

This is a significant if limited development from the peace talks in Geneva. Permission from the Syrian government to lift the siege on parts of the old city of Homs, which for months has left hundreds of people trapped including the very ill and very vulnerable. But though Damascus said women and children could leave immediately, it seems there is a caveat that other civilians, in other words men could leave only if the Syrian government had a list of their names first, it's a condition that the opposition points out could be ominous as information contained in lists could be used to detain or even torture people later.

A brain-dead woman kept live in a hospital in the southern United States because she was pregnant has now been removed from life support. Beth McLeod has more from Washington.

Marlise Munoz was 14 weeks pregnant when she collapsed in November from a suspected blood clot. She was considered brain-dead but was kept life by doctors in a hospital in Fort Worth. Hospital officials argued that state law prohibited them from withdrawing treatment from a pregnant patient. But a state district judge said on Friday that this law was being misapplied and ordered that all life sustaining treatments be removed. The hospital has now followed the court order. The families of Marlise Munoz had argued that she won't want to be on life support and the medical record showed the fetus was severely damaged from oxygen deprivation.

New research suggests the Grand Canyon in the western United States may be much younger than previously thought. Scientists said earlier estimated it to be 70 million years old. Here's our science correspondent Jonathan Amos.

Running for almost 450km and to a depth of 1,800m, it's almost too vast to take it in. Now a new study in the Nature Geoscience journal finds the Grand Canyon has some very good segments, but full system was only cut into the form we know today by Colorado River just over five million years ago.
