A research at New York University Abu Dhabi has found that corals produce chemicals to attract helpful bacteria — a discovery that could assist efforts to protect them and recognise warning signs of diseases.
The study comes at a time when corals around the world are facing increasing threats from climate change, pollution and environmental damage.
Led by Dr Shady Amin, an assistant professor of biology at NYUAD, the study is thought to be the first to demonstrate how corals create a favourable microbiome – a mini ecosystem of microorganisms - around themselves.
Scientists already know that corals have a symbiotic relationship with algae. But how they surround themselves with a unique community of other microorganisms, in particular beneficial bacteria that help them resist disease, is poorly understood.
“We thought there must be some cue that corals produce to attract these microbes and to maintain them,” Dr Amin said.
To test whether corals were producing chemicals to attract, or repel, particular bacteria, the researchers collected samples of seawater at various distances from 18 corals.
Their results were published this week in the journal Communications Biology. Their hypothesis is that corals produce attractants, which act as food source for beneficial bacteria and repellents that can be poisonous to other types of bacteria. They also generate signalling molecules.
“My idea is that probably coral signal to certain bacteria that this is the place to be, to colonise the surface,” said Dr Amin.
Some of the samples were collected from healthy coral, while others came from corals suffering from a condition called white syndrome, which kills the coral and leaves only the white skeleton behind.
The analysis indicated there are particular molecules associated with disease and the hope is that these could be used as early indicators of illness in corals.

“If we see these biomarkers, we can say this coral colony is likely to get diseases. If that's the case, maybe we can come up with some way to mitigate that or monitor it more closely, or assess how widespread the disease would be,” he said.
Temperature is thought to be a factor in white syndrome, said Dr Amin, possibly because pathogens that contribute to the disease are more active in warmer water.
“And maybe the coral is also stressed because of the high heat,” he said.
The researchers are now analysing tissue samples to better understand the way corals may be producing chemicals.
They will also take water samples from corals outside the Arabian Gulf, possibly in the Great Barrier Reef near Australia next year, to see if the same pattern is seen.

School counsellors on mental well-being
Schools counsellors in Abu Dhabi have put a number of provisions in place to help support pupils returning to the classroom next week.
Many children will resume in-person lessons for the first time in 10 months and parents previously raised concerns about the long-term effects of distance learning.
Schools leaders and counsellors said extra support will be offered to anyone that needs it. Additionally, heads of years will be on hand to offer advice or coping mechanisms to ease any concerns.
“Anxiety this time round has really spiralled, more so than from the first lockdown at the beginning of the pandemic,” said Priya Mitchell, counsellor at The British School Al Khubairat in Abu Dhabi.
“Some have got used to being at home don’t want to go back, while others are desperate to get back.
“We have seen an increase in depressive symptoms, especially with older pupils, and self-harm is starting younger.
“It is worrying and has taught us how important it is that we prioritise mental well-being.”
Ms Mitchell said she was liaising more with heads of year so they can support and offer advice to pupils if the demand is there.
The school will also carry out mental well-being checks so they can pick up on any behavioural patterns and put interventions in place to help pupils.
At Raha International School, the well-being team has provided parents with assessment surveys to see how they can support students at home to transition back to school.
“They have created a Well-being Resource Bank that parents have access to on information on various domains of mental health for students and families,” a team member said.
“Our pastoral team have been working with students to help ease the transition and reduce anxiety that [pupils] may experience after some have been nearly a year off campus.
"Special secondary tutorial classes have also focused on preparing students for their return; going over new guidelines, expectations and daily schedules.”
The smuggler
Eldarir had arrived at JFK in January 2020 with three suitcases, containing goods he valued at $300, when he was directed to a search area.
Officers found 41 gold artefacts among the bags, including amulets from a funerary set which prepared the deceased for the afterlife.
Also found was a cartouche of a Ptolemaic king on a relief that was originally part of a royal building or temple.
The largest single group of items found in Eldarir’s cases were 400 shabtis, or figurines.
Khouli conviction
Khouli smuggled items into the US by making false declarations to customs about the country of origin and value of the items.
According to Immigration and Customs Enforcement, he provided “false provenances which stated that [two] Egyptian antiquities were part of a collection assembled by Khouli's father in Israel in the 1960s” when in fact “Khouli acquired the Egyptian antiquities from other dealers”.
He was sentenced to one year of probation, six months of home confinement and 200 hours of community service in 2012 after admitting buying and smuggling Egyptian antiquities, including coffins, funerary boats and limestone figures.
For sale
A number of other items said to come from the collection of Ezeldeen Taha Eldarir are currently or recently for sale.
Their provenance is described in near identical terms as the British Museum shabti: bought from Salahaddin Sirmali, "authenticated and appraised" by Hossen Rashed, then imported to the US in 1948.
