Researchers may be putting humanity on the path to negative carbon emissions after the discovery of a type of highly porous material which can capture and store carbon dioxide more efficiently than ever before.
Carbon capture has become a promising tool in the fight against climate change by lowering atmospheric greenhouse gases and CO2 levels, which are 50 per cent higher than they were a century ago. The Intergovernmental Panel on Climate Change has stressed the importance of carbon capture, saying humanity will not reach its goal of limiting global warming to 1.5°C without it.
However, the current technology only works on highly concentrated sources of carbon, such as those from power plant exhausts and other industrial output, rather than the "ambient" air that we typically breathe.
Chemists at the University of California, Berkeley say they have developed a highly absorbent material which can pull carbon from the air without degradation by water or other contaminants, which is one of the limitations of existing direct air-capture technology. In a new study, published in Nature, researchers outlined how a covalent organic framework (COF) material, described as a kind of ultra-porous organic crystals, can clean ambient air in the environment through direct air capture.
"Direct air capture is like a giant vacuum cleaner that removes CO2 out of the air, captures it, and stores", the study's first author Zihui Zhou told The National. "It helps reduce the overall amount of CO2 in the atmosphere, which is key for tackling climate change".
The COF material builds on previous research developed by Omar Yaghi, a professor of chemistry at UC Berkeley and co-author of the study. His team have spent the last 20 years developing COFs that have a strong enough backbone to withstand contaminants that break it down over repeated cycles.
"I am excited about it because there's nothing like it out there in terms of performance. It breaks new ground in our efforts to address the climate problem," he said.
The Berkeley researchers put a powder of COF in a tube and pushed it through regular outdoor air to see how it would perform. The team were excited to find the carbon concentration dropped to zero, indicating that the material had completely cleaned the air of CO2.
They were further encouraged when it demonstrated excellent stability, maintaining its performance after 100 cycles over 20 days. Ms Zhou said that a mere 200g of the material can take up to 20kg of CO2 in a year, about the same as a tree. Such a discovery could even lead to negative emissions, allowing humanity to reverse some of the damage done by industrial pollutants that have been pumped into the air since the Industrial Revolution.
"Direct air capture is a method to take us back to like it was 100 or more years ago," Ms Zhou said. "Currently, the CO2 concentration in the atmosphere is more than 420 parts per million (ppm), but that will increase to maybe 500 or 550 before we fully develop and employ flue gas capture. So if we want to decrease the concentration and go back to maybe 400 or 300 ppm, we have to use direct air capture."
Prof Yaghi believes the new material could be substituted easily into carbon capture systems already deployed or being piloted to remove CO2 from refinery emissions and capture atmospheric CO2 for storage underground.
"This COF has a strong chemically and thermally stable backbone, it requires less energy, and we have shown it can withstand 100 cycles with no loss of capacity. No other material has been shown to perform like that," Prof Yaghi said. "It's basically the best material out there for direct air capture."

What are the main cyber security threats?
Cyber crime - This includes fraud, impersonation, scams and deepfake technology, tactics that are increasingly targeting infrastructure and exploiting human vulnerabilities.
Cyber terrorism - Social media platforms are used to spread radical ideologies, misinformation and disinformation, often with the aim of disrupting critical infrastructure such as power grids.
Cyber warfare - Shaped by geopolitical tension, hostile actors seek to infiltrate and compromise national infrastructure, using one country’s systems as a springboard to launch attacks on others.
Islamophobia definition
A widely accepted definition was made by the All Party Parliamentary Group on British Muslims in 2019: “Islamophobia is rooted in racism and is a type of racism that targets expressions of Muslimness or perceived Muslimness.” It further defines it as “inciting hatred or violence against Muslims”.

'THE WORST THING YOU CAN EAT'
Trans fat is typically found in fried and baked goods, but you may be consuming more than you think.
Powdered coffee creamer, microwave popcorn and virtually anything processed with a crust is likely to contain it, as this guide from Mayo Clinic outlines:
Baked goods - Most cakes, cookies, pie crusts and crackers contain shortening, which is usually made from partially hydrogenated vegetable oil. Ready-made frosting is another source of trans fat.
Snacks - Potato, corn and tortilla chips often contain trans fat. And while popcorn can be a healthy snack, many types of packaged or microwave popcorn use trans fat to help cook or flavour the popcorn.
Fried food - Foods that require deep frying — french fries, doughnuts and fried chicken — can contain trans fat from the oil used in the cooking process.
Refrigerator dough - Products such as canned biscuits and cinnamon rolls often contain trans fat, as do frozen pizza crusts.
Creamer and margarine - Nondairy coffee creamer and stick margarines also may contain partially hydrogenated vegetable oils.

How Filipinos in the UAE invest
A recent survey of 10,000 Filipino expatriates in the UAE found that 82 per cent have plans to invest, primarily in property. This is significantly higher than the 2014 poll showing only two out of 10 Filipinos planned to invest.
Fifty-five percent said they plan to invest in property, according to the poll conducted by the New Perspective Media Group, organiser of the Philippine Property and Investment Exhibition. Acquiring a franchised business or starting up a small business was preferred by 25 per cent and 15 per cent said they will invest in mutual funds. The rest said they are keen to invest in insurance (3 per cent) and gold (2 per cent).
Of the 5,500 respondents who preferred property as their primary investment, 54 per cent said they plan to make the purchase within the next year. Manila was the top location, preferred by 53 per cent.
