Tropical Storm Debby inundated coastal Georgia and South Carolina with a deluge of rain that could flood Charleston, Savannah and other cities on Tuesday, a day after it slammed into Florida's Gulf Coast as a hurricane.

At least six people have died in Florida and Georgia in the wake of the storm, which is expected to linger over the southeastern and mid-Atlantic coasts for days.

Between 10 inches (25 cm) and 20 inches (51 cm) of rain was expected to fall along parts of Georgia, South Carolina and North Carolina through Friday and cause catastrophic flooding, the National Hurricane Center said. The governors of those states have declared states of emergency.

Cedrick King, a businessman from coastal Brunswick, Georgia, said he and his family packed up their belongings on Tuesday and were ready to make the five-hour drive to Atlanta.

"We're headed north, far away from this storm," he said.

The storm featured 45 mile-per-hour (72 km per hour) winds as it moved slowly just south of Savannah, Georgia, early on Tuesday morning. Heavy rainfall could cause flooding in parts of the mid-Atlantic through Sunday, the center said.

More than 8 inches (20 cm) of rain have already fallen on Savannah and Valdosta, Georgia, the National Weather Service said. Charleston and Hilton Head, South Carolina, have received between 10 and 12 inches (25 and 30 cm) of rain so far, the weather service said, with more on the way.

Charleston Mayor William Cogswell said more than 2 feet (61 cm) of rain is expected in his city before the storm passes. Even at low tide, storm surges of between 4 and 6 feet (1.2 and 1.8 meters) will prevent floodwaters from draining into the sea, he said.

There are "not enough pumps in the world" to handle that much rain, Cogswell said late on Monday. He has since extended a citywide curfew until Wednesday morning.

"Nobody should be out on the streets in these conditions unless it is an absolute emergency," the mayor said.

About 50 miles (80 km) west of Charleston, fears of a breach at the McGrady Dam in Colleton County, part of the state's Lowcountry, prompted the county sheriff's office to warn residents to evacuate immediately on Tuesday morning.

Debby made landfall as a Category 1 hurricane in the Big Bend region of Florida's Gulf Coast on Monday morning, dumping 8 to 16 inches (20 to 41 cm) of rain in parts of central Florida, according to local reports. The storm has been blamed for five deaths in Florida and one near Valdosta, Georgia.

Nearly 110,000 customers were without power in Florida as of Tuesday morning, according to poweroutage.us, down from a peak of 350,000 on Monday. And more than 17,000 were without power in Georgia. Hundreds of flights to and from the state were canceled.

Weather conditions could spawn tornadoes as well, according to the National Hurricane Center. A suspected twister flipped over cars and damaged restaurants in Moncks Corner, South Carolina, about 30 miles (48 km) north of Charleston, early Tuesday morning. Mayor Thomas Hamilton Jr. said there were minor injuries.

The hurricane center said Debby would slow down and move east and off Georgia's shore on Tuesday before turning north and drifting inland over South Carolina near Charleston on Thursday.

Vice President Kamala Harris postponed a presidential campaign stop scheduled this week in Savannah, the Savannah Morning News reported.

Savannah Mayor Van Johnson said the city could expect a "once in a thousand year" rain event.

"This will literally create islands in the city," Johnson said.

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.
