Adding small amounts of liquid soap to certain pesticides can significantly increase their effectiveness against malaria-carrying mosquitoes, scientists found.
Research shows that combining liquid soap and neonicotinoid insecticides can boost their effectiveness more than tenfold.
The findings offer hope in efforts to tackle disease-carrying mosquitoes that have becoming increasingly resistant to insecticides.
The study, published in PLOS Neglected Tropical Diseases, was led by Dr Colince Kamdem and Dr Caroline Fouet of the University of Texas at El Paso.
“Mosquitoes have become strongly resistant to most insecticides over the past two decades,” said Dr Kamdem, the study's lead author.
“It's a race now to develop alternative compounds with new modes of action.”
Dr Fouet added that neonicotinoids are a promising alternative, "but their potency against certain mosquito species needs boosting".
“In this case, soap is the boosting substance," she said.
In 2020, there were an estimated 241 million malaria cases and 627,000 deaths, the World Health Organisation reported.
The disease, prevalent in sub-Saharan Africa, Asia and Latin America, causes symptoms including fever, fatigue, headaches and chills.
Dr Kamdem, who previously worked at Cameroon’s Centre for Research in Infectious Diseases, stumbled on the effectiveness of soap while conducting routine insecticide tests.
He observed more mosquito deaths when a seed oil-based product, a compound similar to kitchen soap, was added to insecticides.
This observation led to the testing of three low-cost, linseed-oil based soaps – Maitre Savon de Marseille, Carolin Savon Noir and La Perdrix Savon – with four different neonicotinoids.
“All three brands of soap increase mortality from 30 per cent to 100 per cent, compared to when the insecticides were used on their own,” said Ashu Fred, the study's first author and a PhD student at the University of Yaounde 1 in Cameroon.
The team reported no benefits when soap was added to pyrethroid insecticides. Despite this, the study opens new avenues in the fight against malaria.
“We would love to make a soap-insecticide formulation that can be used indoors in Africa and be healthy for users," Dr Kamdem said. “There are unknowns as to whether such a formulation will stick to materials like mosquito nets, but the challenge is both promising and very exciting.”

What are NFTs?
Are non-fungible tokens a currency, asset, or a licensing instrument? Arnab Das, global market strategist EMEA at Invesco, says they are mix of all of three.
You can buy, hold and use NFTs just like US dollars and Bitcoins. “They can appreciate in value and even produce cash flows.”
However, while money is fungible, NFTs are not. “One Bitcoin, dollar, euro or dirham is largely indistinguishable from the next. Nothing ties a dollar bill to a particular owner, for example. Nor does it tie you to to any goods, services or assets you bought with that currency. In contrast, NFTs confer specific ownership,” Mr Das says.
This makes NFTs closer to a piece of intellectual property such as a work of art or licence, as you can claim royalties or profit by exchanging it at a higher value later, Mr Das says. “They could provide a sustainable income stream.”
This income will depend on future demand and use, which makes NFTs difficult to value. “However, there is a credible use case for many forms of intellectual property, notably art, songs, videos,” Mr Das says.

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.”

Need to know
The flights: Flydubai flies from Dubai to Kilimanjaro airport via Dar es Salaam from Dh1,619 return including taxes. The trip takes 8 hours.
The trek: Make sure that whatever tour company you select to climb Kilimanjaro, that it is a reputable one. The way to climb successfully would be with experienced guides and porters, from a company committed to quality, safety and an ethical approach to the mountain and its staff. Sonia Nazareth booked a VIP package through Safari Africa. The tour works out to $4,775 (Dh17,538) per person, based on a 4-person booking scheme, for 9 nights on the mountain (including one night before and after the trek at Arusha). The price includes all meals, a head guide, an assistant guide for every 2 trekkers, porters to carry the luggage, a cook and kitchen staff, a dining and mess tent, a sleeping tent set up for 2 persons, a chemical toilet and park entrance fees. The tiny ration of heated water provided for our bath in our makeshift private bathroom stall was the greatest luxury. A standard package, also based on a 4-person booking, works out to $3,050 (Dh11,202) per person.
When to go: You can climb Kili at any time of year, but the best months to ascend are January-February and September-October. Also good are July and August, if you’re tolerant of the colder weather that winter brings.
Do not underestimate the importance of kit. Even if you’re travelling at a relatively pleasant time, be geared up for the cold and the rain.

Ten tax points to be aware of in 2026
1. Domestic VAT refund amendments: request your refund within five years
If a business does not apply for the refund on time, they lose their credit.
2. E-invoicing in the UAE
Businesses should continue preparing for the implementation of e-invoicing in the UAE, with 2026 a preparation and transition period ahead of phased mandatory adoption.
3. More tax audits
Tax authorities are increasingly using data already available across multiple filings to identify audit risks.
4. More beneficial VAT and excise tax penalty regime
Tax disputes are expected to become more frequent and more structured, with clearer administrative objection and appeal processes. The UAE has adopted a new penalty regime for VAT and excise disputes, which now mirrors the penalty regime for corporate tax.
5. Greater emphasis on statutory audit
There is a greater need for the accuracy of financial statements. The International Financial Reporting Standards standards need to be strictly adhered to and, as a result, the quality of the audits will need to increase.
6. Further transfer pricing enforcement
Transfer pricing enforcement, which refers to the practice of establishing prices for internal transactions between related entities, is expected to broaden in scope. The UAE will shortly open the possibility to negotiate advance pricing agreements, or essentially rulings for transfer pricing purposes.
7. Limited time periods for audits
Recent amendments also introduce a default five-year limitation period for tax audits and assessments, subject to specific statutory exceptions. While the standard audit and assessment period is five years, this may be extended to up to 15 years in cases involving fraud or tax evasion.
8. Pillar 2 implementation
Many multinational groups will begin to feel the practical effect of the Domestic Minimum Top-Up Tax (DMTT), the UAE's implementation of the OECD’s global minimum tax under Pillar 2. While the rules apply for financial years starting on or after January 1, 2025, it is 2026 that marks the transition to an operational phase.
9. Reduced compliance obligations for imported goods and services
Businesses that apply the reverse-charge mechanism for VAT purposes in the UAE may benefit from reduced compliance obligations.
10. Substance and CbC reporting focus
Tax authorities are expected to continue strengthening the enforcement of economic substance and Country-by-Country (CbC) reporting frameworks. In the UAE, these regimes are increasingly being used as risk-assessment tools, providing tax authorities with a comprehensive view of multinational groups’ global footprints and enabling them to assess whether profits are aligned with real economic activity.
