The unofficial start of the summer travel season is here, with airlines hoping to avoid the chaos of last year and travelers scrounging for ways to save a few bucks on pricey airfares and hotel rooms.

Some travelers say they will settle for fewer trips than they hoped to take, or they will drive instead of fly. Others are finding different money-saving sacrifices, The Associated Press said.

Stephanie Hanrahan thought she’d save money by planning ahead for her daughter’s birthday trip to Disney World in Florida. Instead, it ended up costing the same as the Dallas-area family’s trip for four to California last summer, so now her husband and son are staying home.

“We just had to grit our teeth,” said Hanrahan, a writer and speaker who also runs a nonprofit, as she and daughter Campbell waited for their flight last week at Dallas Love Field.

The number of people going through US airports hit pandemic-era highs last weekend, and those records are almost certain to be broken over the Memorial Day holiday.

AAA predicts that 37 million Americans will drive at least 50 miles (80 kilometers) from home this weekend, an increase of more than 2 million from Memorial Day last year but still below pre-pandemic numbers in 2019. The Transportation Security Administration expects to screen 10 million travelers between Friday and Monday, a 14% increase over the holiday in 2022 and slightly more than in 2019.

With more travel comes more expense. The average rate for a US hotel room last week was $157 a night, up from $150 in the same week last year, according to hotel data provider STR. And the average daily rate for other short-term rentals such as Airbnb and Vrbo rose to $316 last month, up 1.4% from a year ago, according to AirDNA, which tracks the industry.

There is a bit of good news for drivers, however: The national average for a gallon of regular was $3.56 at midweek, down from $4.60 at this time last year, according to AAA. Renting a car is also cheaper than a year ago, when some popular destinations ran out of vehicles. Travel company Expedia said larger inventories let the companies rent more cars at lower prices.

For air travelers, airline industry officials say carriers have fixed problems that contributed to a surge in flight cancellations and delays last summer, when 52,000 flights were nixed from June through August. Airlines have hired about 30,000 workers since then, including thousands of pilots, and they are using bigger planes to reduce flights but not the number of seats.

“I don’t have the hubris to tell you exactly how the summer is going to go, but we have prepared and we have a robust plan for it,” said Andrew Watterson, chief operating officer at Southwest Airline, which struggled at times over the summer of 2022 and suffered an epic meltdown around Christmas, canceling nearly 17,000 flights.

David Seymour, the chief operating officer of American Airlines, said his staff has fine-tuned a system it uses to predict the impact of storms on major airports and devise a plan for recovering from disruptions. He said it is reducing cancellations.

“It’s going to be a solid summer for us,” Seymour said.

In a report released last month, the Government Accountability Office blamed airlines for an increase in flight cancellations as travel recovered from the pandemic. It also said airlines are taking longer to recover from disruptions such as storms.

Transportation Secretary Pete Buttigieg says the government will hold airlines responsible to treat passengers fairly when the carriers cause cancellations or long delays. But just like the airlines, the Federal Aviation Administration — the agency that manages the nation’s air traffic — has had its own staffing shortages and occasional technology breakdowns that have snarled air travel.

The FAA resorted to nudging airlines to reduce flights in the New York City area this summer, and it opened new flight paths over the East Coast to reduce bottlenecks.

“It’s going to be an ordeal — it’s always an ordeal to travel in the summer,” said travel analyst Henry Harteveldt, “but the airlines have done a lot to improve their ability to operate well this summer.”

Airlines hope that limiting the number of flights will improve reliability and reduce delays. So far, it seems to be working. About one in every 70 US flights have been canceled this year — half the rate of a year ago and lower than in 2019.

Limiting the number of flights also keeps prices above pre-pandemic levels.

A provider of travel data, Hopper, predicts that average domestic airfares will peak next month at $328 for a round-trip ticket, which is down from last summer’s record of $400 but 4% higher than in 2019.

There are some last-minute deals on domestic flights, Hopper found, but international fares are their highest in more than five years, with prices to Europe up 50% from a year ago.

The same thing is happening within Europe, as airlines hold the line on capacity at a time of strong travel demand.

“There is no expectation of seeing cheaper fares in Europe in the next seven or eight months,” says John Grant, an analyst for OAG, a UK-based travel-data provider.

For the travel industry, the big question is how long consumers can keep paying for airline tickets and accommodations while they try to deal with stubborn high inflation, news about layoffs and bank failures, and fear of a recession.

Industry executives say consumers are favoring the experience of travel over other types of spending, but some analysts see cracks in the strong demand for travel that began in early 2022.

Bank of America analysts say data from their credit and debit card customers showed a slowdown in spending in April, as card use fell below year-before levels for the first time since February 2021. They say spending on hotels, which rebounded relatively early from the pandemic, dipped this spring, while the late-recovering cruise industry is still steaming ahead — card spending on cruises rose 37% last month, although from very low levels a year ago.

“Travel remains a bright spot relative to other sectors, but we’re also seeing signs of moderation in the travel space,” said Anna Zhou, an economist for the bank.

When part of a SpaceX rocket re-entered Earth's atmosphere exactly a year ago, it created a spectacular fireball that streaked across Europe's skies, delighting stargazers and sending a team of scientists rushing towards their instruments.

The German team managed to measure the pollution the rocket's upper stage emitted in our planet's difficult-to-study upper atmosphere -- the first time this has been achieved, according to a study published on Thursday.

It is vital to learn more about this little-understood form of pollution because of the huge number of satellites that are planned to be launched in the coming years, the scientists emphasized.

In the early hours of February 19, 2025, the upper stage of a Falcon 9 rocket was tumbling back to Earth when it exploded into a fireball that made headlines from the UK to Poland.

"We were excited to try and test our equipment and hopefully measure the debris trail," the team led by Robin Wing and Gerd Baumgarten of the Leibniz Institute of Atmospheric Physics in Germany told AFP via email.

In particular, the scientists wanted to measure how the rocket polluted what they call the "ignorosphere" -- because it is so difficult to study.

This region between 50 to 100 kilometers (31 to 62 miles) above Earth includes the mesosphere and part of the lower thermosphere.

- 'Harbinger' -

The team used technology called LIDAR, which measures pollution in the atmosphere by shooting out lots of laser pulses and seeing which bounce back off something.

They detected a sudden spike in the metal lithium in an area nearly 100 kilometers above Earth. This plume had 10 times more lithium than is normal in this part of the atmosphere.

The team then traced the plume back to where the rocket re-entered the atmosphere, west of Ireland.

For the first time, this proves it is possible to study pollution from re-entering rockets at such heights before it disperses, the scientists said.

But the impact from this rocket pollution remains unknown.

"What we do know is that one ton of emissions at 75 kilometers (altitude) is equivalent to 100,000 tons at the surface," they said.

The study warned the case was a "harbinger" of the pollution to come, given how many rockets will be needed to launch all the satellites that Earth is planning to blast into space.

Currently, there are around 14,000 active satellites orbiting our planet.
In the middle of last month, China applied for permission to launch around 200,000 satellites into orbit.

Then at the end of January, billionaire Elon Musk's SpaceX applied for permission to launch one million more.

Eloise Marais, a professor of atmospheric chemistry at University College London not involved in the new study, told AFP the research was "really important".

"There is currently no suitable regulation targeting pollution input into the upper layers of the atmosphere," she explained.

"Even though these portions of the atmosphere are far from us, they have potentially consequential impacts to life on Earth if the pollutants produced are able to affect Earth's climate and deplete ozone in the layer protecting us from harmful UV radiation."

The study was published in the journal Communications Earth & Environment.

For more than a century, biology textbooks have stated that vision among vertebrates - people included - is built from two clearly defined cell types: rods for processing dim light and cones for bright light and color. New research involving deep-sea fish shows this tidy division is, in reality, not so tidy.

Scientists have identified a new type of visual cell in deep-sea fish that blends the shape and form of rods with the molecular machinery and genes of cones. This hybrid type of cell, adapted for sight in gloomy light conditions, was found in larvae of three deep-sea fish species in the Red Sea, Reuters reported.

The species studied were: a hatchetfish, with the scientific name Maurolicus mucronatus; a lightfish, named Vinciguerria mabahiss; and a lanternfish, named Benthosema pterotum. The hatchetfish retained the hybrid cells throughout its life. The other two shifted to the usual rod-cone dichotomy in adulthood.

All three are small, with adults measuring roughly 1-3 inches (3-7 cm) long and the larvae much littler. They inhabit a marine realm of twilight conditions, with sunlight struggling to penetrate into the watery depths.

The vertebrate retina, a sensory membrane at the back of the eye that detects light and converts it into signals to the brain, possesses two main types of light-sensitive visual cells, called photoreceptors. They are named for their shape: rods and cones.

"The rods and cones slowly change position inside the retina when moving between dim and bright conditions, which is why our eyes take time to adjust when we flick on the light switch on our way to the restroom at night," said Lily Fogg, a postdoctoral researcher in marine biology at the University of Helsinki in Finland and lead author of the research published in the journal Science Advances.

"We found that, as larvae, these deep-sea fish mostly use a mix-and-match type of hybrid photoreceptor. These cells look like rods - long, cylindrical and optimized to catch as many light particles - photons - as possible. But they use the molecular machinery of cones, switching on genes usually found only in cones," Fogg said.

The researchers examined the retinas of fish larvae caught at depths from 65 to 650 feet (20 to 200 meters). In the type of dim environment they inhabit, rod and cone cells both are usually engaged in the vertebrate retina, but neither works very well. These fish display an evolutionary remedy.

"Our results challenge the longstanding idea that rods and cones are two fixed, clearly separated cell types. Instead, we show that photoreceptors can blend structural and molecular features in unexpected ways. This suggests that vertebrate visual systems are more flexible and evolutionarily adaptable than previously thought," Fogg said.

"It is a very cool finding that shows that biology does not fit neatly into boxes," said study senior author Fabio Cortesi, a marine biologist and neuroscientist at the University of Queensland in Australia. "I wouldn't be surprised if we find these cells are much more common across all vertebrates, including terrestrial species."

All three species emit bioluminescence using small light-emitting organs on their bodies, mostly located on the belly. They produce blue-green light that blends with the faint background light from the sun above. This strategy, called counterillumination, is a common form of camouflage in the deep sea to avoid predators.

"Small fish like these fuel the open ocean. They are plentiful and serve as food for many larger predatory fishes, including tuna and marlin, marine mammals such as dolphins and whales, and marine birds," Cortesi said.

These kinds of fish also engage in one of the biggest daily migrations in the animal kingdom. They swim near the surface at night to feed in plankton-rich waters, then return to the depths - 650 to 3,280 feet (200 to 1,000 meters) - during daytime to avoid predation.

"The deep sea remains a frontier for human exploration, a mystery box with the potential for significant discoveries," Cortesi said. "We should look after this habitat with the utmost care to make sure future generations can continue to marvel at its wonders."

Osaka has received an unusual donation -- 21 kilograms of gold -- to pay for the maintenance of its ageing water system, the Japanese commercial hub announced Thursday.

The donation worth $3.6 million was made in November by a person who a month earlier had already given $3,300 in cash for the municipal waterworks, Osaka Mayor Hideyuki Yokoyama told a press conference.

"It's an absolutely staggering amount," said Yokoyama, adding that he was lost for words to express his gratitude.

"I was shocked."

The donor wished to remain anonymous, AFP quoted the mayor as saying.

Work to replace water pipes in Osaka, a city of 2.8 million residents, has hit a snag as the actual cost exceeded the planned budget, according to local media.
