Whether in busy cities or small towns, people from all walks of life enjoy a cup of coffee as part of their daily routine. The thought of a steaming cup of coffee helps to pull many people worldwide out of bed in the morning. Scientists have consistently linked this ubiquitous drink to lowered risks for illnesses such as heart disease, colon cancer and type 2 diabetes. But its effects on the gut microbiome (肠道菌群) are largely unknown.
Researchers from Harvard University examined samples from over 20, 000 participants who tracked their daily coffee intake. They discovered that regular coffee consumption has a connection to the growth of a specific gut bacterium (细菌). "We don't know much about this bug, but we can place it as likely a good one," said Peter Belenky, a microbiologist at Brown University, who was not involved in the study.
In the largest-ever study, coffee intake was found to increase the number of certain types of bacteria in the gut, but the connection with *Lawsonibacter asaccharolyticus* (溶糖劳森乳杆菌) was the strongest. When coffee was added to lab dishes containing this bacterium, it grew faster. "It's rare to find such a strong and clear link," said Mingyang Song, a co-senior author of the study from Harvard University.
To understand the role of this bacterium in the gut, the researchers looked at substances in the blood of hundreds of participants. They found that higher levels of quinic acid, which can help reduce inflammation (炎症), were strongly related to the growth of *L. asaccharolyticus*. The same was true for hippurate, a substance that shows a more diverse gut microbiome and better gut health.
Based on these results, the scientists are now trying to connect these bacteria and related substances to overall health. Song explained, "This could help us understand if the bacteria are really behind the health benefits of coffee."
Analyzing large datasets from many people is a good way to explore the links between what we eat and drink and the bacteria in our gut. Belenky said, "This study might pave the way for a new approach to food research."

Smart Green Cities: Urban Solutions
(2025·安徽合肥·高三检测)Modern cities face growing challenges from pollution and energy waste, with urban populations expected to reach 5 billion by 2030. 16. D Through innovative technologies and eco-friendly designs, urban areas are transforming into sustainable living spaces that balance human needs with environmental protection.
17. C Solar panels now cover rooftops of office buildings, while wind turbines (涡轮机) spin silently along coastlines. In Amsterdam, floating solar farms on canals generate power without occupying land. These renewable sources provide over 40% of energy in advanced cities like Copenhagen. More importantly, smart grids (电网) automatically adjust power distribution through AI algorithms, reducing power blackout risks by 65% according to EUrban reports.
Transportation systems are undergoing revolutionary changes. 18. E In Singapore, sensor-equipped buses communicate with traffic lights to minimize waiting time, cutting commute (通勤) durations by 18%. Meanwhile, shared electric motorcycles reduce private car usage by 28% in Tokyo's business districts. Oslo has taken this further by banning fossil-fuel vehicles entirely within city centers since 2023.
Green architecture plays a vital role in urban cooling. Vertical gardens covering skyscrapers not only absorb CO₂ but also lower indoor temperatures by 5-8℃. 19. B Rainwater recycling systems installed (安装) in 73% of new Berlin apartments demonstrate this trend, saving 120 liters per household daily. Additionally, bio-concrete walls that absorb pollution are being tested in Mexico City's subway stations.
Citizen participation remains key to success. Mobile apps like "EcoWatcher" allow residents to report environmental issues instantly, with 92% of complaints resolved within 48 hours in Seoul's pilot program. 20. F Through collective efforts supported by technology, smart green cities are becoming achievable realities worldwide.
A. Urban planners prioritize eco-friendly zones nowadays.
B. Such designs also cut air conditioning costs significantly.
C. Energy efficiency starts with renewable power generation.
D. However, smart solutions are reshaping urban environments.
E. Self-driving electric buses replace traditional fuel-based vehicles.
F. Real-time data helps authorities monitor energy consumption patterns.
G. Advanced waste sorting robots have been introduced in subway stations.
