Scientists say they have found the 'key ingredients' to create the first nuclear clock which could advance understanding of time and fundamental physics.
A nuclear clock is a theoretical timekeeping device that measures signals from the nucleus of an atom to provide its 'ticks'.
Although its potential excites scientists, until now it has not been replicated owing to the difficulty of measuring the energy jumps within a nucleus using current technology.
Researchers at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder, were able to utilise a ultraviolet laser to precisely measure the frequency of an energy jump in thorium nuclei embedded in a solid crystal.
While this laboratory demonstration is not a fully developed nuclear clock, it contains all the core technology for one, the scientists say.
“We used a laser referenced to the most precise atomic clock to excite the nucleus of thorium atoms and measure the absolute frequency of the nuclear transition”, researchers told The National.
They added that the measurement was “a million times more precise than previous experiments”.
The research has already yielded unprecedented results, including the ability to observe details in the thorium nucleus's shape that no one had ever observed before. Researchers liken this to seeing individual blades of grass from an aircraft.
Atomic clocks are used to configure international time and play major roles in technologies such as GPS, internet synchronisation, and financial transactions.
Nuclear clocks are generally thought to be more precise than atomic clocks, which measure time by tuning laser light to frequencies that cause electrons to jump between energy levels.
The development of nuclear clocks could mean even more precise navigation systems, faster internet speeds, more reliable network connections and more secure digital communications.
“Imagine a wristwatch that wouldn't lose a second even if you left it running for billions of years,” said NIST and JILA physicist Jun Ye. “While we're not quite there yet, this research brings us closer to that level of precision.”
Scientists focused on thorium-229, an atom whose nucleus has a smaller energy jump than any other known atom, requiring ultraviolet light, which is lower in energy than X-rays.
“Since a nuclear clock is based on a nuclear transition within an atom's nucleus as opposed to an electron transition occurring in the atom's electron shell, nuclear clocks can be less sensitive to issues such as electric magnetic fields”, the researchers added.
“Another simple reason is that the frequency of the thorium nuclear transition is higher than most atomic clock frequencies – in general, a clock that ticks faster is able to measure time with more precision.”
Nuclear clocks could further improve tests of fundamental theories for how the universe works, potentially leading to new discoveries in physics.
For example, they could help detect dark matter or verify if the constants of nature are truly constant, allowing for verification of theories in particle physics without the need for large-scale particle accelerator facilities.
Despite the exciting breakthrough, researchers believe that it would take some time for a nuclear clock to surpass the world's best atomic clocks, adding that both were complimentary to each other, especially when it comes to studying fundamental physics.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Credit Score explained
What is a credit score?
In the UAE your credit score is a number generated by the Al Etihad Credit Bureau (AECB), which represents your credit worthiness – in other words, your risk of defaulting on any debt repayments. In this country, the number is between 300 and 900. A low score indicates a higher risk of default, while a high score indicates you are a lower risk.
Why is it important?
Financial institutions will use it to decide whether or not you are a credit risk. Those with better scores may also receive preferential interest rates or terms on products such as loans, credit cards and mortgages.
How is it calculated?
The AECB collects information on your payment behaviour from banks as well as utilitiy and telecoms providers.
How can I improve my score?
By paying your bills on time and not missing any repayments, particularly your loan, credit card and mortgage payments. It is also wise to limit the number of credit card and loan applications you make and to reduce your outstanding balances.
How do I know if my score is low or high?
By checking it. Visit one of AECB’s Customer Happiness Centres with an original and valid Emirates ID, passport copy and valid email address. Liv. customers can also access the score directly from the banking app.
How much does it cost?
A credit report costs Dh100 while a report with the score included costs Dh150. Those only wanting the credit score pay Dh60. VAT is payable on top.

The flights
Etihad and Emirates fly direct to Kolkata from Dh1,504 and Dh1,450 return including taxes, respectively. The flight takes four hours 30 minutes outbound and 5 hours 30 minute returning.
The trains
Numerous trains link Kolkata and Murshidabad but the daily early morning Hazarduari Express (3’ 52”) is the fastest and most convenient; this service also stops in Plassey. The return train departs Murshidabad late afternoon. Though just about feasible as a day trip, staying overnight is recommended.
The hotels
Mursidabad’s hotels are less than modest but Berhampore, 11km south, offers more accommodation and facilities (and the Hazarduari Express also pauses here). Try Hotel The Fame, with an array of rooms from doubles at Rs1,596/Dh90 to a ‘grand presidential suite’ at Rs7,854/Dh443.
