The study, recently published in Nature Microbiology, reveals how certain bacteria prevent the transfer of genetic material that often carries resistance traits. The discovery centers on a protein known as YokF, which acts as a biological “gatekeeper” by breaking down DNA before it can be shared between neighboring cells, News.Az reports.

Antibiotic resistance remains one of the most pressing global health threats, with resistant infections responsible for hundreds of thousands of deaths annually and projected to rise sharply in the coming decades. A key driver of this crisis is the ability of bacteria to exchange DNA through microscopic structures called nanotubes. These tiny bridges allow plasmids, small DNA molecules that frequently carry resistance genes, to pass from one bacterium to another.
The new findings show that YokF disrupts this process. Instead of allowing DNA to pass freely, the protein degrades genetic material during transfer, effectively blocking the spread of advantageous traits such as drug resistance. This natural defense mechanism limits how quickly bacteria can evolve and adapt in competitive environments.
Scientists say the implications are significant. By mimicking or enhancing this gatekeeping function, future therapies could slow the transmission of resistance genes across bacterial populations. This would not only make infections easier to treat but also extend the lifespan of existing antibiotics, many of which are losing effectiveness due to widespread resistance.
The research also sheds light on how microbes compete for survival. In densely populated environments, such as the human body or soil ecosystems, bacteria often fight for limited resources. Preventing rivals from acquiring beneficial genes gives certain strains a competitive advantage, explaining why such defensive mechanisms evolved in the first place.
Experts note that while the discovery is still at an early stage, it opens a promising avenue for antimicrobial innovation. Instead of directly killing bacteria, which can accelerate resistance, new treatments could focus on controlling gene transfer itself.
As antibiotic resistance continues to challenge healthcare systems worldwide, findings like this highlight the importance of understanding microbial behavior at a fundamental level. By leveraging nature’s own strategies, scientists may be able to develop smarter, more sustainable ways to combat one of modern medicine’s greatest threats.

The talks in Washington between the Middle Eastern neighbors come amid a fragile ceasefire in Lebanon that has seen attacks by Israel and Iran-backed Hezbollah.
Here’s what you need to know:
Israel-Lebanon talks: Officials from Israel and Lebanon will sit down for a second round of high-stakes direct talks this afternoon as Beirut looks to extend a tenuous ceasefire. Today’s talks, mediated by the United States, come days before the US-brokered truce is set to expire. Hezbollah and Israel have both conducted military strikes during the truce, including an Israeli strike on southern Lebanon Wednesday that killed one journalist and seriously injured another. Lebanon’s prime minister accused Israel of war crimes after that attack.
Trump’s order: Trump has ordered the US Navy to fire on any Iranian boats that are placing mines in the Strait of Hormuz, the critical energy chokepoint that carries about one-fifth of all global crude oil. The order comes as fears grow that the presence of mines in the crucial waterway could spark economic repercussions that outlive the war itself.
US boards another tanker: The US Defense Department announced today that it boarded a “sanctioned stateless vessel” in the Indian Ocean overnight. The vessel, M/T Majestic X, was carrying oil from Iran, the department said in a post on X.
Military planners meet: The United Kingdom and France have told military planners from dozens of nations in London today that “practical military options” will be needed to ensure freedom of navigation in the Strait of Hormuz.
In the strait: Two dry bulk carriers crossed the Strait of Hormuz on Thursday, according to the trade analytics company Kpler. One of the carriers, Tema Express, is owned and operated by Hapag-Lloyd — making this the first confirmed transit of the strait by a vessel operated by the German carrier since the start of the conflict, Rebecca Gerdes, a data analyst at Kpler, told CNN.
Deadline unclear: Trump said there is no deadline for ending the war with Iran, the ceasefire, or Tehran’s response to his request for a peace proposal. The US Navy currently has 19 ships in the Middle East, including two aircraft carriers, and seven ships in the Indian Ocean, a US official said.
Israel’s warning: Israel is ready “to return Iran to the dark ages,” Defense Minister Israel Katz said, adding that Israel is “awaiting a green light” from the United States to resume the war and “complete the elimination of the Khamenei dynasty and to return Iran to the dark ages.”

While battery range defines capability and charging determines usability, cost ultimately determines whether a buyer commits to the transition. This theme goes beyond the initial purchase price and extends into a broader financial framework known as total cost of ownership, News.az reports.
***
Consumers are no longer asking only how much an electric vehicle costs to buy. They are increasingly focused on long term expenses, including charging, maintenance, depreciation, and resale value. Leading manufacturers such as Tesla, BYD, and Changan Automobile are competing not only on performance but also on affordability and value over time. The following FAQ explainer examines the most important financial questions shaping the EV market.
Are electric vehicles more expensive to buy than petrol cars
The upfront cost of electric vehicles has historically been higher than that of internal combustion engine vehicles. This is primarily due to the cost of batteries, which represent a significant portion of the total vehicle price.
However, the gap is narrowing. Advances in battery production, economies of scale, and increased competition have reduced manufacturing costs. Entry level EVs are becoming more accessible, particularly in markets where companies like BYD and Changan Automobile offer competitively priced models.
In some regions, government incentives such as subsidies, tax reductions, and exemptions from registration fees further reduce the effective purchase price. These incentives play a critical role in making EVs financially competitive.
What is total cost of ownership and why does it matter
Total cost of ownership refers to the complete financial cost of owning a vehicle over its lifetime. It includes purchase price, fuel or energy costs, maintenance, insurance, taxes, and depreciation.
For electric vehicles, this concept is particularly important. While the initial purchase price may be higher, lower operating costs can offset the difference over time.
Consumers increasingly evaluate EVs based on this long term perspective rather than short term expense. This shift in mindset is a key factor driving adoption.
Are EVs cheaper to run than petrol cars
Electric vehicles are generally cheaper to operate on a daily basis. Electricity is typically less expensive than petrol or diesel when measured per kilometer.
Charging at home offers the lowest cost, especially when using off peak electricity rates. Even public charging, while sometimes more expensive, often remains competitive compared to fuel costs.
Efficiency is another advantage. EVs convert a higher percentage of energy into movement, reducing overall consumption. This contributes to lower running costs over time.
How much does it cost to charge an EV
Charging costs vary depending on electricity prices, battery size, and charging method. Home charging is usually the most economical option, while fast public charging can be more expensive.
For a typical electric vehicle, the cost per full charge can range from relatively low amounts at residential rates to higher costs at commercial charging stations. However, when calculated per kilometer, EVs often remain cheaper than petrol vehicles.
Energy prices fluctuate by region, making local conditions an important factor in cost calculations.
Do electric vehicles require less maintenance
Maintenance costs are one of the strongest financial advantages of electric vehicles. EVs have fewer moving parts compared to internal combustion engines, which reduces the likelihood of mechanical failure.
There is no need for oil changes, exhaust system repairs, or many of the routine services associated with petrol vehicles. Brake wear is also reduced due to regenerative braking systems.
However, EVs still require maintenance for components such as tires, suspension, and software updates. While not maintenance free, overall costs are generally lower.
What about battery replacement costs
Battery replacement is one of the most frequently searched concerns related to EV ownership. While batteries can be expensive to replace, the likelihood of needing a replacement during the vehicle’s lifetime is relatively low.
Most manufacturers provide warranties covering 8 years or around 160,000 kilometers. Real world data suggests that batteries often last longer than this period.
Costs have also declined significantly over time due to improvements in technology and production efficiency. As the industry evolves, replacement costs are expected to continue decreasing.
Do EVs hold their value over time
Depreciation is a key component of total cost of ownership. Historically, electric vehicles experienced higher depreciation rates due to concerns about battery lifespan and rapid technological change.
However, this trend is shifting. As confidence in battery durability increases and demand for EVs grows, resale values are improving.
Brands with strong reputations, such as Tesla, tend to retain value more effectively. Meanwhile, increasing competition from companies like BYD and Changan Automobile is influencing pricing dynamics across the market.
Are there hidden costs associated with EV ownership
While EVs offer many cost advantages, there are potential additional expenses to consider.
Home charger installation can require an upfront investment, particularly if electrical upgrades are needed. Public charging costs can also vary significantly depending on location and provider.
Insurance premiums may differ based on vehicle type and market conditions. In some cases, repair costs can be higher due to specialized components and limited availability of parts.
Understanding these factors is essential for accurate cost assessment.
How do government incentives affect EV affordability
Government policies play a significant role in reducing the cost of electric vehicles. Incentives can include direct subsidies, tax credits, reduced registration fees, and exemptions from road taxes.
These measures lower the effective purchase price and improve the overall financial appeal of EVs. In some markets, incentives can make electric vehicles comparable in price to traditional cars.
However, incentives vary by region and may change over time. Buyers must consider current policies when evaluating costs.
Is it financially worth buying an EV today
The financial value of an EV depends on individual circumstances, including driving habits, access to charging, and local energy prices.
For drivers with high mileage, the lower operating costs of EVs can lead to significant savings over time. For those with access to home charging, the cost advantage is even greater.
In many cases, the total cost of ownership is already competitive with or lower than that of petrol vehicles. As prices continue to decline, this advantage is expected to strengthen.
How does large scale production impact EV costs
Mass production is a key factor in reducing EV prices. As manufacturers increase output, economies of scale lower the cost of batteries and components.
Tesla has focused on vertical integration and large scale manufacturing to reduce costs. BYD’s control over battery production gives it a competitive advantage in pricing. Changan Automobile is leveraging partnerships and platform strategies to expand its EV offerings.
This industrial scaling is accelerating the transition toward more affordable electric vehicles.
What role do energy prices play in EV economics
Electricity prices directly influence the cost of operating an EV. In regions with low electricity costs, EV ownership becomes significantly more economical.
Conversely, high energy prices can reduce the cost advantage, particularly when relying on public fast charging.
The integration of renewable energy sources, such as solar power, can further reduce costs for some users. This adds another dimension to the financial analysis of EV ownership.
Will EVs become cheaper than petrol cars in the future
Industry trends indicate that electric vehicles are on track to achieve price parity with petrol cars. Continued advancements in battery technology, combined with increased competition and production scale, are driving costs down.
Some forecasts suggest that EVs could become cheaper to produce than internal combustion vehicles within the next decade. When combined with lower operating costs, this would make EVs the more economical choice in most scenarios.
Why cost remains a central theme in EV adoption
Cost is the ultimate decision making factor for most consumers. While environmental benefits and technological innovation are important, financial considerations often determine purchasing behavior.
The focus on total cost of ownership reflects a more mature understanding of EV economics. Consumers are looking beyond initial price and evaluating long term value.
This shift is critical for the continued growth of the EV market.
What is the long term outlook for EV affordability
The long term outlook for EV affordability is positive. Prices are declining, technology is improving, and competition is increasing.
As more manufacturers enter the market and production scales up, consumers will have access to a wider range of options at different price points.
At the same time, infrastructure development and policy support will enhance the overall value proposition of electric vehicles.
Conclusion
Cost and total ownership represent the financial foundation of the electric vehicle transition. They determine accessibility, influence adoption rates, and shape consumer perceptions.
While challenges remain, the trajectory is clear. Electric vehicles are becoming more affordable, both in terms of purchase price and long term operation.
For many consumers, the question is no longer whether EVs are economically viable, but when they will become the default choice. As costs continue to decline and benefits increase, that transition appears increasingly inevitable.

“As a pastor I cannot be in favor of war,” Leo told reporters flying with him from Malabo, Equatorial Guinea, a week after US President Donald Trump attacked the pontiff for his stance on the Middle East conflict.
“I would like to encourage all to make efforts to look for answers that come from a culture of peace and not from a place of hate and division.”
Leo said that the US and Israel’s bombing of Iran had created a “chaotic situation for the global economy” along with “a whole population in Iran, of innocent people, which is suffering because of this war.” Highlighting the human cost of conflict, the pope revealed that he carries a photo of a Lebanese Muslim boy, who had carried a sign welcoming the pontiff to the country at the end of last year, and who was killed in the war.
The pope, who alternated between English, Spanish and Italian when answering questions, also criticized the Iranian regime’s killing of protesters in his first remarks on the topic.
Asked if he condemned Tehran’s deadly crackdown on protests, Leo said, “I condemn all actions that are unjust, I condemn the taking of people’s lives, I condemn capital punishment, I believe that human life is to be respected.
“When a regime, when a country, takes decisions which take away the lives of people unjustly then obviously that is something that should be condemned.”
