For a third day, extreme rainfall pounded the southern Chinese province of Hainan, known as China's "Hawaii", amid the transit of yet another tropical cyclone, leaving the island half-submerged in a year of record-breaking wet weather.

Cities in Hainan including Sanya, famed for its palm trees, seafront hotels and sandy beaches, remained waterlogged on Tuesday due to Tropical Storm Trami to the south. On Monday, Sanya logged 294.9mm (11.6 inches) of rainfall over a 24-hour window, the most for any day in October since 2000.

Trami made landfall in central Vietnam on Sunday after a slow trek across the South China Sea from the Philippines, where it left at least 125 people dead and 28 missing. While Hainan did not take a direct hit from Trami, Chinese authorities took no chances, recalling all fishing vessels and evacuating over 50,000 people.

China's entire eastern coastline has been tested by extreme weather events this year - from the violent passage of Super Typhoon Yagi across Hainan in September to the strongest tropical cyclone to strike Shanghai since 1949. Scientists warn more intense weather is in the offing, spurred by climate change.

"In October, the national average precipitation was 6.3% higher than the same period in previous years," Jia Xiaolong, a senior official at the National Climate Centre, said at a news conference on Tuesday.

Last week, the water along China's Bohai Sea inexplicably rose up to 160 cm (5.2 feet) in a matter of hours despite the absence of any wind, leading to a tidal surge that flooded the streets of Tianjin and many cities in the northern provinces of Hebei and Liaoning.

"It's hard to imagine how much power was needed to push such a large area of sea water to one place," Fu Cifu, an official at the National Marine Environmental Forecasting Centre, told state-run Xinhua news agency at the time.

China is historically no stranger to floods, but its prevention infrastructure and emergency response planning are coming under increasing pressure as record rains flood populous cities, ravage crops and disrupt local economies.

Amid disaster recovery efforts this summer, authorities had to provide billions of dollars in additional funding to support reconstruction in multiple regions from the south to the northeast of China.

In July, the country suffered 76.9 billion yuan ($10.8 billion) in economic losses from natural disasters, with 88% of those losses caused by heavy rains and floods from Typhoon Gaemi, the most for the month of July since 2021.

Astronomers have identified a new space corridor that could cut hundreds of days from the journey to Mars by taking advantage of a natural route followed by some asteroids as they travel between planets.

The distance between Earth and Mars constantly changes depending on their positions and orbital speeds around the Sun. It reaches its shortest point when Earth lies directly between the Sun and the Red Planet, a phenomenon known as “Mars opposition,” which occurs roughly every 26 months.

Even so, reaching Mars currently takes between seven and 10 months, even using the fastest spacecraft available. But the newly identified space corridor, which opens during periods when the two planets are relatively close, could reduce the total mission time to just 153 days.

Space agencies typically plan planetary missions by analyzing planetary orbital data to determine optimal flight paths and fuel requirements. However, this newly identified corridor was discovered through the study of asteroid orbital data instead.

Astronomers explored whether asteroid trajectories could reveal hidden shortcuts through space, focusing on asteroid 2001 CA21, which is believed to cross the orbital paths of both Earth and Mars.

Researchers analyzed the asteroid’s close approaches to Mars, a trajectory that could allow spacecraft to follow a more direct route to the Red Planet. They also examined Mars opposition windows in 2027, 2029, and 2031 to determine which offered the best conditions for a shorter journey.

The study found that 2031 is the only year in which the geometry of Earth and Mars aligns favorably with the asteroid’s orbital plane, making the rapid route possible.

The researchers said in the study, published in Acta Astronautica and cited by The Independent: “The 2031 Mars opposition supports two complete round-trip missions in less than one year while aligning with the orbital plane associated with asteroid CA21, demonstrating how small-body orbital data can help identify rapid interplanetary transfer opportunities at an early stage.”

They added: “This study presents an innovative engineering methodology for designing rapid interplanetary missions.”

The research team hopes future studies into the orbital dynamics of near-Earth asteroids will contribute to developing faster and more efficient designs for interplanetary space travel.


Study Shows How Potato-based Diet Changed Genetics of Andean People

Indigenous people in the Andes domesticated the potato - a great source of starch, vitamins, minerals and fiber - 6,000 to 10,000 years ago, making this tuber a central part of their diet.

These people then experienced genetic adaptations beneficial for such a diet that are still seen in their descendants living in Peru.

New genomic research documents how these descendants - speakers of the Quechua language of the once-great Inca Empire - underwent fortification involving a gene called AMY1 that is involved in starch digestion, a function useful for people with a potato-centric diet.

The study found that these people possess an average of 10 copies of AMY1 - two to four more than most people. No other known population globally exceeds that number. According to Reuters, the study also showed that the onset of these genetic changes in this population coincided with the advent of potato domestication.

"It is a wonderful case of culture shaping biology," said evolutionary and anthropological geneticist Omer Gokcumen of the University at Buffalo, one of the senior ⁠authors of the ⁠research published this week in the journal Nature Communications.

"This highlights the importance of dietary adaptation in human evolutionary history, with implications for metabolism, health and the impact of domestication events on human biology," said UCLA anthropological geneticist Abigail Bigham, also one of the study's senior authors.

At the molecular level, AMY1 governs an enzyme called amylase that is present in saliva and is responsible for breaking down starch in the mouth when a person eats starchy foods. A person with more copies of the gene may produce more of the enzyme.

This greater dosage, the researchers said, may facilitate better metabolism of ⁠high-starch diets. Amylase may also be involved in regulating the microbiome - the body's natural collection of microbes - which can shift with dietary change.

Lactose tolerance is another example of diet-driven evolutionary adaptation, involving a gene related to an enzyme that breaks down lactose in milk.

In the new study, the researchers analyzed genomic data spanning more than 3,700 people across 85 populations in the Americas, Europe, Africa and Asia, including 81 native Quechua speakers of Andean ancestry in Peru.

The researchers said it appears that over time evolutionary forces favored extra copies of AMY1 in the ancient Andeans.

In order to become widespread, a genetic variant may provide some advantage.

"Therefore, one hypothesis is that people with more copies of AMY1 may have been better able to process starch-rich foods, including potatoes," University at Buffalo doctoral student and study co-lead author Luane Landau said.

"Individuals who were born with the higher copies of AMY1 may have had an ⁠advantage as compared to ⁠individuals who did not have it, and left more descendants over generations.

Over time, this could explain why the genetic version linked to high AMY1 copy number became more common in Andean populations today," Landau said.

Potatoes represented a reliable food source - a crop that thrived at the high altitudes these people inhabited.

"They were one of the main sources for calories in the ancient Andean diet," University at Buffalo doctoral student and study co-lead author Kendra Scheer said.

Potatoes were at the heart of the Inca food supply. They were brought to Europe and the rest of the world following the Spanish conquest of the Inca Empire in the 16th century.

"Their global culinary spread is a testament to their broad likeability," Bigham said.

At markets in the Andean highlands and elsewhere in Peru, Quechua speakers sell a wide variety of potatoes, with flesh of various colors including purple, blue, red, gold, white and even black.

"In Peru, there are about 3,000 to 4,000 different kinds of potato, but the majority of the world has access to only a select few strains. Therefore, there is a whole world of different types of French fries that are possible," Scheer said.

Court Rules in ‘Sunbed War,’ Towels Lose

A German tourist has won a payout of more than €900 (£850) after he was unable to secure a sun lounger due to other guests reserving them with towels, according to BBC.

The man, who has not been identified, was on holiday in Greece with his family in 2024, and said he spent 20 minutes a day trying to find a sun lounger, despite waking up at 06:00.

He then sued his tour operator for allowing the reservation system, arguing the sunbeds were reserved so often, they were unusable.

Judges at a district court in Hanover ruled in his favor, and said the family of four were entitled to a larger refund on their package holiday as it had been “defective.”

The man had initially paid €7,186 (£6,211) to take his wife and their two children on the package holiday to Kos, an island in Greece.

In his arguments to court, he said that his tour operator had failed to enforce the resort's ban on towel reserving, and did not confront guests who were engaging in the practice.

He added that even when his family rose at 06:00, loungers were unavailable, and his children were forced to lie on the floor.

Though the tour operator had initially paid out a refund of €350 (£302), judges in Hanover ruled the family was entitled to a refund of €986.70 (£852.89).

They said that although the travel company did not run the hotel and could not ensure every customer could access a sunbed at any given time, the operator did have an obligation to make sure there was an organizational structure that would guarantee a “reasonable” ratio of sunbeds to guests.

Many tourists will have encountered “sunbed wars” or “dawn dash” on holiday, which is the practice of reserving loungers with towels.
