Growing port congestion demands smarter management. In a new study, researchers developed a dynamic forecasting framework using real-time operation indicators from a two-stage queuing model to predict vessel turnaround time. Tested with data from Busan Port, the model achieved up to 28% higher accuracy than traditional methods. By improving berth planning and resource allocation, this approach can significantly enhance efficiency and reduce delays in global port operations.

Cumberland, B.C., was built on coal mining—both literally and practically. Thousands of workers were employed and millions of tonnes of coal were exported over 80 years before the mines were shuttered, leaving deep holes in the ground and a deeper void in the village’s economy. Thanks to a partnership with the University of Victoria-led Accelerating Community Energy Transformation (ACET) initiative, Cumberland is planning for a future built on clean energy that comes from the maze of abandoned mine shafts and extraction tunnels that snake beneath its streets.

Researchers have found that a specific body profile—higher muscle mass combined with a lower visceral fat to muscle ratio—tracks with a younger brain age, according to a study being presented next week at the annual meeting of the Radiological Society of North America (RSNA). Visceral fat is hidden deep within the abdominal cavity, surrounding vital internal organs.

Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor.

Diets of wild orangutans are “culturally-dependent”: adult Sumatran orangutans have knowledge of around 250 edible food items, which is more than any one individual can attain without learning from other individuals.

Developmental experiments “in silico”: using computer simulations based on 12 years of observations on wild orangutans, researchers show that orangutans fail to develop “adult-like” diets if deprived of key social interactions that facilitate learning.

Deep roots of cultural inheritance: adult orangutan’s diets are the product of information that many different individuals must have discovered and learnt from each other. Humans’ capacity to accumulate broad cultural repertoires – to breadths no individual could produce alone – is potentially a capacity that evolved at least 13 million years, in our common ancestor with great apes.

An international study published today in Communications Biology has used unique coral reefs in Papua New Guinea to determine the likely impact of ocean acidification on coral reefs in the face of climate change.

Oceans are becoming more acidic as they absorb carbon dioxide from the atmosphere, and that acid will dissolve coral limestone. But it’s hard to predict what impact this will have on whole ecosystems from studies using aquariums and models.

The research team, led by the Australian Institute of Marine Science (AIMS), studied entire coral reefs, locally enriched with CO₂ that is seeping from the sea floor, near some of Papua New Guinea’s remote shallow submarine volcanoes.

Dr. Katharina Fabricius, a coral researcher at AIMS in Townsville and senior author on the paper, says the research has revealed which species can thrive under lifelong exposure to elevated CO₂.

“These unique natural laboratories are like a time machine,” said Dr Fabricius.  

“The CO₂ seeps have allowed us to study the reefs’ tolerance limits and make predictions. How will coral reefs cope if emissions are in line with the Paris Agreement level emissions? How will they respond to higher CO₂ emissions scenarios?”
