From reproductive rights to local weather change to Big Tech, The Independent is on the bottom when the story is growing. Whether it is investigating the financials of Elon Musk’s pro-Trump PAC or producing our newest documentary, ‘The A Word’, which shines a light-weight on the American girls preventing for reproductive rights, we all know how necessary it’s to parse out the info from the messaging.
At such a essential second in US historical past, we’d like reporters on the bottom. Your donation permits us to maintain sending journalists to talk to either side of the story.

Bones found within the wreckage of the Mary Rose are offering clues about how somebody’s collarbone modifications relying on whether or not they’re left- or right-handed.
The findings suggest that being right-handed may have put extra stress on the fitting collarbone as crew members carried out repeated ship-related actions.
The evaluation of centuries-old human skeletal stays might deepen immediately’s understanding of how bone chemistry modifications with age.
The vessel, which was a part of the Tudor navy and Henry VIII’s flagship, sank between Portsmouth and the Isle of Wight on July 19 1545 whereas partaking with French ships within the Battle of the Solent.
When it was excavated within the late twentieth century, the ship’s artefacts and the crew’s skeletons have been well-preserved, that means analysis may very well be carried out into the belongings, look, and well being of the sailors.
More persons are naturally right- than left-handed, and, on the time when the Mary Rose sank, left-handedness was related to witchcraft and due to this fact strongly discouraged.
Having grown up fascinated by the Mary Rose, it has been superb to have the chance to work with these stays
Dr Sheona Shankland, Lancaster University
The new research by Dr Sheona Shankland and colleagues at Lancaster University sheds new gentle on the biology of 12 males aged 13 to 40 who went down with the ship.
As they aged, the mineral content material of their bones elevated, whereas protein content material decreased, albeit to a lesser diploma, based on the research.
It additionally indicated that these age-related modifications have been extra pronounced in the fitting collarbone (clavicle) than within the left.
Assuming a choice for right-handed folks among the many crew, the findings point out that handedness may have affected the make-up of the clavicle, possibly via placing extra pressure on their proper facet as they carried out duties on board.
Dr Shankland stated: “Having grown up fascinated by the Mary Rose, it has been amazing to have the opportunity to work with these remains.
“The preservation of the bones and the non-destructive nature of the technique allows us to learn more about the lives of these sailors, but also furthers our understanding of the human skeleton, relevant to the modern world.”
This research sheds new gentle on what we all know in regards to the clavicle and its mineralisation.
Professor Adam Taylor, University of Lancaster
Professor Adam Taylor stated: “This study sheds new light on what we know about the clavicle and its mineralisation.
“The bone plays a critical role in attaching your upper limb to the body and is one of the most commonly fractured bones.”
The new analysis explored how the chemistry of bone may change in response to bodily exercise and ageing, so an individual’s bone chemistry may maintain clues about their life-style.
In this case, the researchers analysed collarbones from the wreck utilizing a non-destructive laser method known as Raman spectroscopy.
The researchers famous that extra analysis on the Mary Rose clavicles can be wanted to raised perceive these findings.
– The findings are printed within the Plos One journal.
