Scientists at Cambridge University have created a way to power electrical devices using algae, in a move which could eventually mean it replacing batteries.
Researchers have used a widespread species of blue-green algae to power a microprocessor continuously for over a year using nothing but ambient light and water.
Their system has the potential to be a reliable and renewable way to power small devices in the future.
The system, comparable in size to an AA battery, contains a type of non-toxic algae called Synechocystis that naturally harvests energy from the sun through photosynthesis.
The tiny electrical current it generates then interacts with an aluminium electrode and is used to power a microprocessor.
The system is made of common, inexpensive and largely recyclable materials and the researchers believe it will enable the initiative to be replicated hundreds of thousands of times to power large numbers of small devices as part of the Internet of Things.
The Internet of Things is a vast and growing network of electronic devices — each using only a small amount of power — that collect and share real-time data via the internet.
Using low-cost computer chips and wireless networks, many billions of devices are part of the network — from smartwatches to temperature sensors in power stations.
“The growing Internet of Things needs an increasing amount of power, and we think this will have to come from systems that can generate energy, rather than simply store it like batteries,” said Professor Christopher Howe in the University of Cambridge’s Department of Biochemistry, joint senior author of the study paper.
“Our photosynthetic device doesn’t run down the way a battery does because it’s continually using light as the energy source.”
In the experiment, the device was used to power an Arm Cortex M0+, which is a microprocessor used widely in Internet of Things devices.
It operated in a domestic environment and semi-outdoor conditions under natural light and associated temperature fluctuations, and after six months of continuous power production the results were submitted for publication.
“We were impressed by how consistently the system worked over a long period of time — we thought it might stop after a few weeks but it just kept going,” said Dr Paolo Bombelli, from the University of Cambridge’s Department of Biochemistry, first author of the paper which has been published in the journal Energy and Environmental Science.
The algae does not need feeding, because it creates its own food as it photosynthesises and despite the fact that photosynthesis requires light, the device can continue producing power during periods of darkness.
The researchers think this is because the algae processes some of its food when there’s no light, and this continues to generate an electrical current.
The Internet of Things is expected to grow to one trillion devices by 2035, requiring a vast number of portable energy sources.
The researchers say that powering trillions of Internet of Things devices using lithium-ion batteries would be impractical.
They say it would need three times more lithium than is produced across the world annually and traditional photovoltaic devices are made using hazardous materials that have adverse environmental effects.
The work was a collaboration between the University of Cambridge and Arm, a company leading the design of microprocessors.
The research was funded by the National Biofilms Innovation Centre.

KEY DEVELOPMENTS IN MARITIME DISPUTE
2000: Israel withdraws from Lebanon after nearly 30 years without an officially demarcated border. The UN establishes the Blue Line to act as the frontier.
2007: Lebanon and Cyprus define their respective exclusive economic zones to facilitate oil and gas exploration. Israel uses this to define its EEZ with Cyprus
2011: Lebanon disputes Israeli-proposed line and submits documents to UN showing different EEZ. Cyprus offers to mediate without much progress.
2018: Lebanon signs first offshore oil and gas licencing deal with consortium of France’s Total, Italy’s Eni and Russia’s Novatek.
2018-2019: US seeks to mediate between Israel and Lebanon to prevent clashes over oil and gas resources.
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.”

Tips for job-seekers
- Do not submit your application through the Easy Apply button on LinkedIn. Employers receive between 600 and 800 replies for each job advert on the platform. If you are the right fit for a job, connect to a relevant person in the company on LinkedIn and send them a direct message.
- Make sure you are an exact fit for the job advertised. If you are an HR manager with five years’ experience in retail and the job requires a similar candidate with five years’ experience in consumer, you should apply. But if you have no experience in HR, do not apply for the job.

Key findings of Jenkins report
- Founder of the Muslim Brotherhood, Hassan al Banna, "accepted the political utility of violence"
- Views of key Muslim Brotherhood ideologue, Sayyid Qutb, have “consistently been understood” as permitting “the use of extreme violence in the pursuit of the perfect Islamic society” and “never been institutionally disowned” by the movement.
- Muslim Brotherhood at all levels has repeatedly defended Hamas attacks against Israel, including the use of suicide bombers and the killing of civilians.
- Laying out the report in the House of Commons, David Cameron told MPs: "The main findings of the review support the conclusion that membership of, association with, or influence by the Muslim Brotherhood should be considered as a possible indicator of extremism."
Generational responses to the pandemic
Devesh Mamtani from Century Financial believes the cash-hoarding tendency of each generation is influenced by what stage of the employment cycle they are in. He offers the following insights:
Baby boomers (those born before 1964): Owing to market uncertainty and the need to survive amid competition, many in this generation are looking for options to hoard more cash and increase their overall savings/investments towards risk-free assets.
Generation X (born between 1965 and 1980): Gen X is currently in its prime working years. With their personal and family finances taking a hit, Generation X is looking at multiple options, including taking out short-term loan facilities with competitive interest rates instead of dipping into their savings account.
Millennials (born between 1981 and 1996): This market situation is giving them a valuable lesson about investing early. Many millennials who had previously not saved or invested are looking to start doing so now.

Unresolved crisis
Russia and Ukraine have been locked in a bitter conflict since 2014, when Ukraine’s Kremlin-friendly president was ousted, Moscow annexed Crimea and then backed a separatist insurgency in the east.
Fighting between the Russia-backed rebels and Ukrainian forces has killed more than 14,000 people. In 2015, France and Germany helped broker a peace deal, known as the Minsk agreements, that ended large-scale hostilities but failed to bring a political settlement of the conflict.
The Kremlin has repeatedly accused Kiev of sabotaging the deal, and Ukrainian officials in recent weeks said that implementing it in full would hurt Ukraine.
