A liver suspended surgeon over the "avoidable deaths" of 8 patients has been referred to police by the local Health Board.
The son of a dementia victim has described the effects of the disease on the day David Cameron announced a doubling in research funding.
A soldier who lost his arm in Afghanistan has become the first Briton to benefit from a new type of prosthetic controlled by the mind.
An investigation into the deaths of three babies and one woman at Furness General Hospital has uncovered a catalogue of failures.
Nittaya and Chester Hendrickson, Joshua Titcombe and Alex Davey-Brady all died following mistakes made by midwives within the maternity ward at the hospital.
A report from the Health Service Ombudsman found midwives given the role of supervising their peers concluded there had been no errors despite obvious evidence of mistakes.
The Government is aiming to "roll out" a scan for Alzheimer's disease across the NHS "as quickly as possible", the health secretary told Daybreak.
Jeremy Hunt said the department of health wanted to see "two thirds of people" who suffer from dementia to be diagnosed "by the end of this Parliament".
"The main thing that is exciting about this, is that it is a real palava getting a dementia diagnosis because you have to do these memory tests and people's memories does start to go a bit in old age."
The father of a baby who died amid a series of failings at Furness General Hospital has urged the health secretary to adopt a series of measures published in a damning report into the scandal.
James Titcombe, whose son Joshua died when he was nine days old, welcomed the "important" report, which he said could prevent future deaths if recommendations on "serious incidents" were implemented:
"I would say to Jeremy, 'please make sure the recommendations are implemented' because this report could actually change the learning from serious incidents in maternity."
An Alzheimer's scan which will be introduced on the NHS is a "big step forward", according to an industry expert.
However, Alzheimer's Society Chief Executive Jeremy Hughes warned the scan would not be immediately widely available.
"One hospital doing one scan today does not mean it is available across the NHS.
"And the biggest problem we have is still the fear that people have of dementia. They don't even go to the doctor to talk about it and we need to change that."
Families of the three babies and one mother who died at the hands of University Hospitals of Morecombe Bay said the damning report into midwifery shows "just how dangerous the wrong type of leadership can be in the NHS".
Liz Brady and Simon Davey, who lost their son Alex, Car Hendrickson, whose wife Nittaya and son Chester both died, and James Titcombe, who lost his son Joshua, called the failings "catastrophic".
"As well as highlighting the catastrophic and repeated failures of the SHA (Strategic Health Authority), today's report also makes some substantial recommendations for changing the system of midwifery supervision in the UK.
"We welcome these recommendations wholeheartedly and are grateful to Dame Julie Mellor for investigating the concerns properly and producing a report that we hope will make maternity services in the UK safer for other mothers and babies in the future."
Victims dubbed the ombudsman at the time "not fit for purpose" and "a cog" which was "set in motion by the last Government".
It is now feared a total of 15 babies and two mothers died needlessly at unit over the last decade with another 15 newborns suffering brain damage or other serious injuries.
Industry experts praised David Cameron's plans to double funding into dementia research, with one charity hoping it would "set a good example" across the international community.

We boast some of the world's leading scientists in dementia, and these announcements are a clear backing of their crucial work - this support must continue.
We hope this package of announcements will set a good example to other G8 nations to galvanise international research efforts.
The Prime Minister is expected to announce plans to double Government funding of dementia research in his keynote speech at the first G8 dementia summit later today.
David Cameron also wants to see a similar level of investment from the private and charitable sectors.
- Government investment will double from £66 million to £122 million in 2025.
- A newly established UK Dementia Platform will allow different research teams across the country to share data in order to increase the scale and scope of their work.
- The Medical Research Council is channelling £50 million into dementia research over the next five years.
The Prime Minister is expected to agree to measures designed to boost research into dementia, such as international information-sharing, in a speech at a G8 summit later today.
Britain is hosting the international dementia summit in which David Cameron will give the keynote address.
He is expected to stress the importance of achieving scientific breakthroughs in order to slow down, or even prevent, the onset of the debilitating brain condition, now believed to afflict 36 million people around the world.
The Conservative leader will also focus on the role life sciences plays in the British economy, with GSK announcing £200 million of investment at its manufacturing plants at Ware, Hertfordshire, and Worthing, Sussex, and UCB announcing a further £3 million.
Cardiff and Vale University Health Board has set up a helpline for anyone who is concerned about the surgical care they received in relation to liver surgery between February 2011 and October 2012.
The helpline number is: 0800 952 0244.
It will be open from noon to 8pm from tomorrow until Friday.
Bosses at Cardiff and Vale University Health Board revealed the full extent of their findings as the partner of one of the eight patients whose death was "unavoidable", began legal action to find out exactly what happened.
Martyn Rogers, 66, of Newport, died of blood poisoning and acute liver failure in summer 2012 at University Hospital Wales.
His death on July 25 came one week after surgeon Dr Berry carried out the vital operation to remove tumours from his liver.
Lawyers acting for Maria Davies, his partner of 40 years,have launched their own investigation into what happened in the case of Mr Rogers.
