Coral reef symbiosis: Paying rent with sugar and fat
Scientists have revealed how coral-dwelling microalgae harvest nutrients from the surrounding seawater and shuttle them out to their coral hosts, sustaining a fragile ecosystem that is under threat.
Testing the boundaries: study reveals inner workings of cricket teams
A study by QUT researchers found cricket batsmen who were close to reaching personal milestones were likely to alter their strategy in a way which, at first sight, seems detrimental to the team.
Lower-cost metal 3-D printing solution available
3-D printing of plastic parts to prototype or manufacture goods is becoming commonplace in industry, but there is an urgent need for lower-cost 3-D printing technology to produce metal parts. New substrate release solutions that offer easy, less expensive alternatives to aluminum parts removal during gas metal arc weld 3-D printing are described in an article in 3-D Printing and Additive Manufacturing.
The most effective surgical procedure for extreme obesity should be used with caution
Based on five-year follow-up of patients in a randomized clinical trial, researchers have concluded that gastric bypass is the preferred treatment for extreme obesity. This is despite the fact that it is not as effective in reducing body weight as the so-called duodenal switch.
Study shows iron supplementation after blood donation shortens hemoglobin recovery time
A National Institutes of Health-funded study comparing low dose iron supplementation to no supplementation in blood donors found that supplementation significantly reduced the time to recovery of post-donation lost iron and hemoglobin -- an iron-rich protein that carries oxygen in red blood cells throughout the body.
Smaller pre-surgery radiation targets reduces long term side effects, not survival rates
The Journal of Clinical Oncology just published clinical trial results that more firmly establish that for patients with soft tissue sarcomas, image-guided radiation directed towards a smaller target area great reduced long term negative impact without effecting survival rates.
DNA 'cage' could improve nanopore technology
Researchers from Brown University have designed a tiny cage that can trap a single strand of DNA after it has been pulled through a nanopore. While caged, biochemical experiments can be performed on the strand, which can then be zipped back through the nanopore. The device could enable researchers to look for probe a DNA before and after a reaction takes place.
Historic Indian sword was masterfully crafted
The master craftsmanship behind Indian swords was highlighted when scientists and conservationists from Italy and the UK joined forces to study a curved single-edged sword called a shamsheer. The study, led by Eliza Barzagli of the Institute for Complex Systems and the University of Florence in Italy, is published in Springer's journal Applied Physics A - Materials Science & Processing.
Smoking thins vital part of brain
A major study by an international team including the Montreal Neurological Institute at McGill University and the University of Edinburgh shows new evidence that long-term smoking could cause thinning of the brain's cortex. The cortex is the outer layer of the brain in which critical cognitive functions such as memory, language and perception take place. Interestingly, the findings also suggest that stopping smoking helps to restore at least part of the cortex's thickness.
Crowdfunding helps solve rare disease mystery
The cost of identifying the source and progression of rare diseases remains prohibitive for many families, but there is hope for them in our Internet age. Researchers at Tel Aviv University recently concluded a successful experiment to identify a novel genetic mutation as the source of a specific rare disease, and their experiment was supported through crowdfunding.
