Sitting on the edge of the world, Sydney is considered as one of the world’s greatest cities for a reason. Want to relax yourself in Sydney? This shortlist of things to do and see in Sydney should point you in the right direction.

Hit the beaches

Everyone knows about Bondi Beach and its Icebergs pool, restaurants and the crashing waves are the postcard image of Sydney. Bondi is a great place to start. But after you’ve caught some sun or taken a surf lesson with Let’s Go Surfing, we’d suggest taking the Coogee Coastal Walk. Beginning at the Bondi Icebergs swim club, the 3.7-mile walk affords amazing cliffside views of rock pools and bays.

Catch a show

Sydney is full of events and performances every night of the week. The first place that jumps to mind is the iconic Sydney Opera House, designed by Jørn Utzon. A UNESCO World Heritage site, this incredible piece of architecture doesn’t just do opera. You’ll also find stand-up comedy, ballets, and more. But it’s not the only place in Sydney putting on a show. The 1920s State Theatre, in the central business district, is known to host international ballets, concerts and world-class orchestras.

Go to the zoo

From the skyline views to the charming grounds, there’s a reason why Sydney’s Taronga Zoo attracts more than 1 million visitors every year. The expansive space plays host to more than 4,000 animals, including tigers, giraffes, kangaroos, platypus, koalas, Komodo dragons, elephants, lions, chimps and more. Love it so much that you never want to leave? Stay the night in one of its luxury safari（狩猎）tents.

Climb the bridge

Nicknamed “the coathanger”, the Sydney Harbour Bridge opened in 1932. Like the Sydney Opera House, it was an engineering masterpiece that was way ahead of its time. Sure, you can walk or cycle across the bridge, but the best way to appreciate the architectural wonder is up close and personal.

The Cambodian Government’s Fisheries Administration and WWF announced that the Irrawaddy dolphin population in the Mekong River numbers just 89. The number is a slight decline from the estimate of 92 in 2018, but shows that the population has stabilized. In recent years after decades of sharp decline.

Critically, the survey’s findings also indicate a positive survival rate of calves through to adulthood, with a “recruitment rate” of 4.22%, signalling an improving trend for the dolphin population. “Although the survey confirmed that the number of river dolphins in Cambodia has stabilized, the population size is still small, so stronger conservation action is urgently needed,” said Mr. Seng Teak, WWF Country Director.

The Irrawaddy dolphins are fully protected under Cambodia’s Fisheries Law. The dolphins, however, continue to face great danger. Gill nets, development of upstream dams, overfishing, and illegal fishing practices such as electrofishing are among major known threats to the survival of the species.

Effective conservation action in recent years has halted the decline in the population, but more is required to ensure that the population expands. The Fisheries Administration and WWF are committed to continuing to work gather with the local communities and other partners to make collective efforts to carry out the recommendations of the 2020 population report.

These recommendations include enforcement of the fisheries law and the ban on illegal gill net use in the protected dolphin habitat, continued robust monitoring of the species population, and management of the Ramsar site in Stung Treng province to improve natural fish stocks for food and prey enhancement for both the local communities and the dolphins.

A smile is the key to a thousand doors, but deploying it in every situation without mastery of its use is dangerous, says a new social science study.

Scientists say it takes a great many muscles to smile; scientists at Queen’s University Belfast in a recent study found that subtle differences in the way in which a person smiled had not-so-subtle impacts on the opinions which the test participants had about the smiler. “Smiling at another person does not always lead to trust and cooperation,” said Dr. Stephanie Carpenter from the University of Michigan, a co-author of the study. “Subtle differences in a smile can definitely have a real impact on whether people trust each other and choose to cooperate. In fact, the way you smile in a good or bad situation can impact whether people trust you.

“Think about movie villains, for example in James Bond films,” said Dr. Magdalena Rychlowska from Queen’s University, who led the research published in Cognition and Emotion journal. “They often make happy smiles when something bad has happened or is about to happen. This context makes these otherwise happy and normal smiles feel threatening and unpleasant.” She adds, “The findings of this study show the power of subtle facial expressions and the positive consequences that an affiliation smile can have in difficult situations. It also highlights the importance of social context — a happy smile that could be read as a signal of trustworthiness in one setting can, but in another setting, it can be seen as the evidence of bad intentions.”

Mastery of the smile then, can be an excellent way of getting out of difficult social situations, while the lack thereof can be an excellent way of getting into one.
