As the performers took the stage and the traditional drum beat gained momentum, Sudanese refugees sitting in the audience were moved to tears. Hadia Moussa said the melody reminded her of the country's Nuba Mountains, her family's ancestral home.
"Performances like this help people mentally affected by the war. It reminds us of the Sudanese folklore and our culture," she said.
Sudan has been engulfed by violence since April 2023, when war between the Sudanese military and the paramilitary Rapid Support Forces broke out across the country. The conflict has turned the capital, Khartoum, into an urban battlefield and displaced 4.6 million people, according to the UN migration agency, including more than 419,000 people who fled to Egypt.
A band with 12 Sudanese members now lives with thousands of refugees in Egypt. The troupe, called “Camirata," includes researchers, singers and poets who are determined to preserve the knowledge of traditional Sudanese folk music and dance to keep it from being lost in the ruinous war, The Associated Press said.
Founded in 1997, the band rose to popularity in Khartoum before it began traveling to different states, enlisting diverse musicians, dancers and styles. They sing in 25 different Sudanese languages. Founder Dafallah el-Hag said the band's members started relocating to Egypt recently, as Sudan struggled through a difficult economic and political transition after a 2019 popular uprising unseated longtime ruler Omar al-Bashir. Others followed after the violence began. El-Hag arrived late last year.
The band uses a variety of local musical instruments on stage. El-Hag says audiences are often surprised to see instruments such as the tanbour, a stringed instrument, being played with the nuggara drums, combined with tunes of the banimbo, a wooden xylophone.
“This combination of musical instruments helped promote some sort of forgiveness and togetherness among the Sudanese people,” el-Hag said, adding that he is eager to revive a museum in Khartoum that housed historic instruments and was reportedly looted and damaged.
Fatma Farid, 21, a singer and dancer from Kordofan, moved to Egypt in 2021. Her aunt was killed in 2023 when an explosive fell on their house in al-Obeid, the capital of North Kordofan.
“The way I see art has changed a lot since the war began," she said. "You think of what you present as an artist. You can deliver a message,” she said.
Kawthar Osman, a native of Madani city who has been singing with the band since 1997, feels nostalgic when she sings about the Nile River, which forms in Sudan from two upper branches, the Blue and White Nile.
“It reminds me of what makes Sudan the way it is,” she said, adding that the war only “pushed the band to sing more for peace.”
Over 2 million Sudanese fled the country, mostly to neighboring Egypt and Chad, where the Global Hunger Index has reported a “serious” level of hunger in Chad. Over half a million forcibly displaced Sudanese have sought refuge in Chad, mostly women and children.
Living conditions for those who stayed in Sudan have worsened as the war spread beyond Khartoum. Many made hard decisions early in the war either to flee across frontlines or risk being caught in the middle of fighting. In Darfur, the war turned particularly brutal and created famine conditions, with militias attacking entire villages and burning them to the ground.
Armed robberies, lootings and the seizure of homes for bases were some of the challenges faced by Sudanese who stayed in the country's urban areas. Others struggled to secure food and water, find sources for electricity and obtain medical treatment since hospitals have been raided by fighters or hit by airstrikes. Communications networks are often barely functional.
The performers say they struggle to speak with family and friends still in the country, much less think about returning.
“We don’t know if we’ll return to Sudan again or will see Sudan again or walk in the same streets,” Farid 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.
