According to Noël Coward, mad dogs and Englishmen are the only creatures that go out in the midday sun, but a research team from the University of Ulm, Germany, would add another animal: Saharan silver ants.

During an earlier trip to the salt pans of Tunisia (South of the Atlas Mountains on the northern edge of the desert) to study the Cataglyphis fortis, a type of Saharan ant, another type of silver ant caught the attention of the research team, with its outstanding speed and its adaptability to high temperature in the noon despite its short legs.

The team returned to Tunisia in 2015 to study the speed of the Saharan silver ant and published its findings four years later, on Wednesday, in the Journal of Experimental Biology, showing these insects are the fastest ants ever recorded, reaching speeds of 855mm/s (0.855m/s).

In a report published on the British Biologists Foundation's website, the study lead author, Sarah Pfeffer, said: "Our first uneasy mission was to locate the nests of these ants. However, once the team had located a nest, it was simply a matter of connecting an aluminum channel to the entrance and placing a feeder at the end to lure the ants out. After the ants have found the food, they shuttle back and forth in the channel and we mounted our camera to film them from the top."

Calculating the insects' top speeds, Pfeffer and her colleagues were impressed to find the animals hit an extraordinary 855mm/s during the hottest part of the desert day, making them the world's fastest ant and placing them close to the top of the list of world record-breaking creatures, alongside Australian tiger beetles (9 kilometers per hour).

The insect's speed wasn't the only surprising fact, but also its capacity to maintain this speed despite living in a very hot environment, and the shortness of its legs compared to other types of ants studied in the same region including the Cataglyphis fortis.

"We found that this ant used a different strategy to reach high speeds, outweighing the long-legged Cataglyphis Fortis. Apparently, the silver ant's shorter leg length was compensated with high step frequencies, exceeding 40 Hz," said Pfeffer.

Drinking a few cups of caffeinated coffee or tea every day may help in a small way to preserve brain power and prevent dementia, researchers reported on Monday.

People with the highest daily intake of caffeinated coffee had an 18% lower risk of developing dementia compared to those with the lowest such intake, according to a study based on responses to questionnaires by 132,000 U.S. adults spanning four decades.

The study, published in JAMA, also found that the people with the highest intake had a lower rate - by nearly 2 percentage points - of ‌self-perceived memory ‌or thinking problems compared to those with ‌the ⁠lowest intake.

Results were ‌similar with caffeinated tea, but not with decaffeinated beverages, the researchers said.

While the findings are encouraging, the study does not prove caffeine helps protect the brain, they said.

The magnitude of caffeine's effect, if any, was small, and there are other better-documented ways to protect cognitive function as people age, study leader Dr. Daniel Wang ⁠of Harvard Medical School said in a statement.

Lifestyle factors linked with lower risks of ‌dementia include physical exercise, a healthy diet ‍and adequate sleep, according to previous ‍research.

"Our study suggests that caffeinated coffee or tea consumption can ‍be one piece of that puzzle," Wang said.

The findings were most pronounced in participants who consumed two to three cups of caffeinated coffee or one to two cups of caffeinated tea daily, the researchers reported.

Those who drank caffeinated coffee also showed better performance on some objective tests of cognitive function, according to the ⁠study funded by the National Institutes of Health.

Further research is needed to validate the factors and mechanisms responsible for the findings, the researchers said.

They noted that bioactive ingredients in coffee and tea such as caffeine and polyphenols have emerged as possible factors that reduce nerve cell inflammation and damage while protecting against cognitive decline.

"We also compared people with different genetic predispositions to developing dementia and saw the same results - meaning coffee or caffeine is likely equally beneficial for people with high and low genetic risk of developing ‌dementia," study coauthor Dr. Yu Zhang of the Harvard T.H. Chan School of Public Health said in a statement.

AlUla Governorate is welcoming the holy month of Ramadan this year with a wide range of diverse tourism experiences that reflect the area’s distinctive character and rich cultural heritage, reinforcing its position as one of the Kingdom’s most prominent destinations to visit during the holy month.

During Ramadan, AlUla offers an integrated experience catering to different visitor preferences, including guided stargazing experiences, cultural events, and night markets, in addition to traditional dining experiences for Iftar and Suhoor, embodying the depth of AlUla’s cultural heritage and local identity.

The Ramadan programs in AlUla include a variety of standout events, such as Ramadan experiences at Maraya Hall, a cultural market, and live performances in the atmosphere of Ashar Valley, alongside heritage tours in AlUla Old Town that narrate stories of AlUla and its Ramadan customs, including the award-winning Incense Road Experience, SPA reported.

The programs also feature seasonal art exhibitions hosted across multiple cultural venues, including Design Space AlUla, the fourth edition of Desert X AlUla, and the Arduna exhibition at AlUla Oasis, in addition to experiences combining art, nature, and stargazing at Daimumah Oasis in collaboration with AlUla Manara.

Visitors are also offered tours to prominent archaeological sites, including Hegra, Dadan, and Jabal Ikmah, to explore ancient sites dating back centuries BCE and view unique rock inscriptions, as well as adventure experiences ranging from dinner and stargazing in Sharaan, hot-air balloon rides, mountain hiking trails, and safari tours.

These programs come as part of efforts to enhance AlUla’s tourism experience during the holy month of Ramadan and provide diverse options that meet visitor expectations, contributing to the growth of tourism activity and showcasing the governorate’s natural and cultural assets.

The National Center for Wildlife (NCW) announced that the total number of wildlife animals released under its breeding and reintroduction programs for locally threatened species has exceeded 10,000 animals, an achievement reflecting the scale of the center’s sustained efforts to develop wildlife, restore ecosystems, and enhance biodiversity across various regions of the Kingdom.

The releases carried out by the center over the past years included more than 80 priority wildlife species, including reem gazelles (sand gazelles), Arabian oryx, Idmi gazelles, mountain ibex, houbara bustards, ostriches, and sandgrouse, as part of efforts aimed at supporting the recovery of natural populations of these species and enhancing their sustainability within their environmental and historical ranges, SPA reported.

CEO of NCW Dr. Mohammad Qurban noted that release operations are among the key tools for restoring ecosystems and reducing ecological imbalance, as the return of wildlife to their natural habitats contributes to protecting biodiversity and improving environmental quality, which in turn supports habitat integrity, the continuity of plant and animal components, and the enhancement of ecosystem functions over the long term.

NCW continues to implement its strategic plans to develop wildlife, protect endangered species, and enhance the efficiency of natural habitat management through expanding breeding programs, enhancing applied scientific research, building national capacities, and applying the best international practices in biodiversity management, in addition to raising environmental awareness, engaging local communities, and supporting eco-tourism, thereby contributing to achieving the objectives of the Saudi Green Initiative and Saudi Vision 2030, and the National Environment Strategy, toward thriving and sustainable wildlife, biodiversity, and ecosystems.
