A new device which mimics the ability of plants to photosynthesise could hasten the transition away from fossil fuels, say the Cambridge scientists who created it.
The test unit converts light, carbon dioxide and water into a clean and stable fuel that can either be used directly or converted into hydrogen.
It operates wirelessly and without an external power source, and despite being only three inches in size, it can be scaled up for use on an industrial level akin to solar farms, according to the researchers.
The quest to replicate photosynthesis has long been a challenge for science. The problem has been "converting as much of the sunlight as possible into the fuel you want, rather than be left with a lot of waste", said Dr Qian Wang of Cambridge's Department of Chemistry and lead scientist on the project.
Producing a scalable renewable fuel that can be easily stored and transported has also proved an intractable problem.
In 2019, Reisner Lab developed a solar reactor based on an artificial leaf design. It works similarly to the 2020 device from Cambridge by converting sunlight into clean fuel. However, a reliance on solar cell components means it is less scalable. The new test unit uses photosheet technology: sheets made up of semiconductor powders which can be prepared in large quantities, easily and cost-effectively.
“We were surprised how well it worked in terms of its selectivity – it produced almost no by-products,” said Dr Wang. “Sometimes things don’t work as well as you expected but this was a rare case where it actually worked better.”
Efficiencies still need to be improved before any commercial deployment can be considered. The researchers are now working to optimise further the system and improve efficiency. Additionally, they are exploring other catalysts for using on the device to get different solar fuels.

Four motivational quotes from Alicia's Dubai talk
“The only thing we need is to know that we have faith. Faith and hope in our own dreams. The belief that, when we keep going we’re going to find our way. That’s all we got.”
“Sometimes we try so hard to keep things inside. We try so hard to pretend it’s not really bothering us. In some ways, that hurts us more. You don’t realise how dishonest you are with yourself sometimes, but I realised that if I spoke it, I could let it go.”
“One good thing is to know you’re not the only one going through it. You’re not the only one trying to find your way, trying to find yourself, trying to find amazing energy, trying to find a light. Show all of yourself. Show every nuance. All of your magic. All of your colours. Be true to that. You can be unafraid.”
“It’s time to stop holding back. It’s time to do it on your terms. It’s time to shine in the most unbelievable way. It’s time to let go of negativity and find your tribe, find those people that lift you up, because everybody else is just in your way.”

New UK refugee system
- A new “core protection” for refugees moving from permanent to a more basic, temporary protection
- Shortened leave to remain - refugees will receive 30 months instead of five years

Get inspired
Here are a couple of Valentine’s Day food products that may or may not go the distance (but have got the internet talking anyway).
Sourdough sentiments: Marks & Spencer in the United Kingdom has introduced a slow-baked sourdough loaf dusted with flour to spell out I (heart) you, at £2 (Dh9.5). While it’s not available in the UAE, there’s nothing to stop you taking the idea and creating your own message of love, stencilled on breakfast-inbed toast.
Crisps playing cupid: Crisp company Tyrells has added a spicy addition to its range for Valentine’s Day. The brand describes the new honey and chilli flavour on Twitter as: “A tenderly bracing duo of the tantalising tingle of chilli with sweet and sticky honey. A helping hand to get your heart racing.” Again, not on sale here, but if you’re tempted you could certainly fashion your own flavour mix (spicy Cheetos and caramel popcorn, anyone?).

Dr Afridi's warning signs of digital addiction
Spending an excessive amount of time on the phone.
Neglecting personal, social, or academic responsibilities.
Losing interest in other activities or hobbies that were once enjoyed.
Having withdrawal symptoms like feeling anxious, restless, or upset when the technology is not available.
Experiencing sleep disturbances or changes in sleep patterns.
What are the guidelines?
Under 18 months: Avoid screen time altogether, except for video chatting with family.
Aged 18-24 months: If screens are introduced, it should be high-quality content watched with a caregiver to help the child understand what they are seeing.
Aged 2-5 years: Limit to one-hour per day of high-quality programming, with co-viewing whenever possible.
Aged 6-12 years: Set consistent limits on screen time to ensure it does not interfere with sleep, physical activity, or social interactions.
Teenagers: Encourage a balanced approach – screens should not replace sleep, exercise, or face-to-face socialisation.
