The first of three anticipated "supermoons" was seen around the world last night.
The "perigree moon" phenomenon - which occurs when the moon reaches the closest point on its elliptical orbit - makes the satellite appear larger and brighter than usual.
It is the first of three anticipated in as many months - with the others expected on 10 August and 9 September.
Regular eye tests could "complement" existing procedures as an initial screen in diagnosing Alzheimer's, the Australian science agency the Commonwealth Scientific and Industrial Research Organisation has said. Shaun Frost, who led one of the studies, added:
If further research shows that our initial findings are correct, it could potentially be delivered as part of an individual's regular eye check-up.
The high resolution level of our images could also allow accurate monitoring of individual retinal plaques as a possible method to follow progression and response to therapy.
Regular eye tests could in future be used to diagnose early-stage Alzheimer's, new research suggests.
Early trials of two different techniques show that a key Alzheimer's biomarker can be identified in the retina and lens of the eye.
Both methods were able to distinguish between probable Alzheimer's patients and healthy volunteers with a high level of accuracy.
Although the research is still at an early stage, further work could see such tests used as a first step in identifying individuals with Alzheimer's. Early diagnosis of Alzheimer's is essential to developing effective treatments that do more than alleviate the condition's symptoms.
At least 33 people, including 29 women, were killed in a raid by gunmen on a Baghdad housing complex on Saturday night.
A minimum of 18 others were wounded in the attack, police said.
Officials from a local hospital and from the interior ministry confirmed the casualties, the Associated Press said.
The motive behind the killings remains unclear, but Iraqi police say there are suspicions that the buildings were being used as a brothel.
The Israeli force has attacked a site in northern Gaza used to launch long-range rockets, Israeli military spokesman Lieutenant Colonel Peter Lerner said. Militants opened fire, wounding four commandos, but the launch site was hit.
Lt. Col. Lerner told Reuters the forces had "completed their mission" and that the results of the raid "would be the first published ground activity" by naval troops in Gaza, in an offensive that Palestinian officials said has killed more than 149 Palestinians, many of them civilians.
Lerner said Israel would drop leaflets in northern Gaza's Beit Lahiya to urge thousands of residents to evacuate ahead of planned strikes there.
The Church of England's governing body is preparing for a vote on whether to introduce women bishops at a key meeting.
Members of the General Synod will be asked to give final approval to legislation introducing women bishops, paving the way for the first female diocesan bishop in the Church of England by early next year.
The vote comes after the plan was derailed by just six votes cast by lay members in November 2012, causing shock and bitter recriminations within the Church of England and prompting threats of an intervention by Parliament.
Israel has deployed ground troops inside Gaza to raid a rocket launching site in the Palestinian territory.
It was the first time that Israeli ground troops are known to have entered Gaza in the current offensive.
But the operation, carried out by special forces, did not appear to be the beginning of a broad ground offensive.
Gaza's police headquarters have been completely demolished in the latest rocket attacks by Israel.
