SUDAN : Renowned Sudanese folkloric singer Asia Madani passes away in Cairo

Well-known Sudanese singer and percussionist Asia Madani, who lived in Cairo, passed away on Sunday, the Sudanese Artists Union in Egypt reported.

Madani was born in Wad Madani, the capital of the Gezira State in central Sudan.

She started her career in her early years, moving to Egypt in the early 2000s, and quickly found her place in the country’s music scene.

Her initial breakthrough was on the Cairo Opera House stage.

Later, she became best known for presenting Sudanese folk music mixed with modern musical rhythms.

Madani performed with her troupe and joined many ensembles that focused on traditional and folkloric music of the south, earning herself the title of Messenger of Sudanese Folklore.

The star often spoke about her deep love for Sudanese rhythms, explaining that her journey in music began at a young age.

She highlighted how she learned diverse musical and vocal rhythms from different regions of Sudan — from the south to the north and the central areas — which greatly influenced her artistic style.

The singer was deeply influenced by the works of iconic Egyptian singers like Mohamed Abdel-Wahab and Abdel-Halim Hafez and even reinterpreted some of Sayed Darwish’s songs in her unique voice.

Moreover, Madani participated in the Nile Project, which she co-founded and which brought together African musicians from the Nile basin countries.

She was also featured in the documentary Far From the Nile presenting the project. The film was screened in the main competition of the Cairo International Film Festival (2022), winning awards.

Among her best-known songs were Jibal Al-Nuba (Mountains of Nubia), Al-Qamar Badawi (The Moon Shines), and Al-Zul (The Man).

Additionally, Madani participated in many international festivals and founded a children’s choir for Sudanese children in Egypt.

Numerous artists have expressed their sorrow after Madani’s sudden death.

“May God have mercy on you, forgive you, and grant you eternal rest. You were a true artist who loved her country and lived in her second country, Egypt. You were a strong person, never afraid to speak the truth, kind, pure-hearted, and a true artist who sang for the people everything she felt in a genuine way. Goodbye,” singer and songwriter Hani Adel wrote on Facebook. 

Sudanese director Amjad Abu Al-Alaa wrote on his Facebook account: “A great loss, Asia.”

“To be an artist with a beautiful voice and a following is a normal thing, but what is extraordinary is to have a message in what you present, to have your own artistic project based on Sudanese identity, the unity of the Sudanese people, its uniqueness, enriching and renewing its heritage, presenting it in an attractive way, and touring the world proudly and persistently,” Sudanese media personality Dalia Al-Tahir wrote on her X account. 

“This is what the true artist, the revolutionary soul from the heart of the country, Asia Madani, excelled in,” she expressed.

SAUDI ARABIA : Makkah hosts 10th international military Qur’an contest

179 participants from 32 Islamic countries to compete, promote moderate Islamic values.

The 10th International Military Qur’an Memorization Competition launched on Saturday in Makkah, attracting 179 participants from 32 countries.

Organized by the General Administration of Religious Affairs of the Armed Forces under the patronage of Defense Minister Prince Khalid bin Salman, the event promotes the significance of the Qur’an, encourages its memorization, and highlights Saudi Arabia’s role in serving Islam’s holy book and as the custodian of Islam’s holiest sites.

The competition features six categories: full Qur’an memorization; 20-part, 10-part, five-part, and three-part memorization; and a special category for recitation and tajweed (proper pronunciation).

Parallel activities include a Qur’anic forum for religious affairs directors and imams, showcasing Saudi Arabia’s efforts in Qur’an printing, translation, and distribution.

The forum also discusses the Qur’an’s moral values, the Kingdom’s contributions through its ministries, and the impact of tajweed on understanding the Qur’an.

Additionally, the General Administration of Religious Affairs offers training programs for religious affairs personnel across the armed forces, focusing on Qur’anic teaching methods and enhancing the skills of instructors and competition judges.

Maj. Gen. Mesfer Al-Issa, director of the General Administration of Religious Affairs and competition supervisor, described the event as a significant initiative to honor the Qur’an.

Al-Issa emphasized the Kingdom’s commitment to hosting this event, reflecting the leadership’s dedication to serving the Qur’an.

In an interview with Arab News, he highlighted the event’s profound impact on participants, especially as it takes place in the holy cities of Makkah and Madinah.

Al-Issa said that the Qur’an guides soldiers, shaping their character and values, and encouraging psychological, behavioral, and spiritual stability.

Soldiers grounded in the Qur’an and Sunnah are more balanced and resilient, contributing to the development of morally and spiritually strong armed forces, he said.

The 14-day event will include 10 days in Makkah before moving to Madinah for four days, where participants will visit the Prophet’s Mosque and other Islamic landmarks.

Judges, including imams from the Two Holy Mosques and Qur’anic scholars, use an advanced electronic evaluation system called “Insaf” (Fairness) for transparent scoring.

Contestants receive immediate feedback on memorization, pronunciation, tajweed, and error rates.

Al-Issa said that soldiers are selected through year-long national competitions to identify top military memorizers.

The competition also serves as a platform for military personnel from Islamic nations to promote moderate Islamic values and a proper understanding of the Qur’an through scientific forums.

Al-Issa said that the competition strengthens the Qur’an’s role in Islamic armed forces, supporting efforts to memorize, recite, and reflect on its teachings.

This helps build a generation of soldiers rooted in Islamic knowledge and guided by noble values, he added.

EGYPTIAN-AMERICAN : Freeze-frame: U of A researchers led by Physicist Prof. Mohammed Hassan develop World’s Fastest Microscope that can see electrons in motion

Imagine owning a camera so powerful it can take freeze-frame photographs of a moving electron – an object traveling so fast it could circle the Earth many times in a matter of a second. Researchers at the University of Arizona have developed the world’s fastest electron microscope that can do just that.

They believe their work will lead to groundbreaking advancements in physics, chemistry, bioengineering, materials sciences and more.

“When you get the latest version of a smartphone, it comes with a better camera,” said Mohammed Hassan, associate professor of physics and optical sciences. “This transmission electron microscope is like a very powerful camera in the latest version of smart phones; it allows us to take pictures of things we were not able to see before – like electrons. With this microscope, we hope the scientific community can understand the quantum physics behind how an electron behaves and how an electron moves.”

Hassan led a team of researchers in the departments of physics and optical sciences that published the research article “Attosecond electron microscopy and diffraction” in the Science Advances journal. Hassan worked alongside Nikolay Golubev, assistant professor of physics; Dandan Hui, co-lead author and former research associate in optics and physics who now works at the Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences; Husain Alqattan, co-lead author, U of A alumnus and assistant professor of physics at Kuwait University; and Mohamed Sennary, a graduate student studying optics and physics.

A transmission electron microscope is a tool used by scientists and researchers to magnify objects up to millions of times their actual size in order to see details too small for a traditional light microscope to detect. Instead of using visible light, a transmission electron microscope directs beams of electrons through whatever sample is being studied. The interaction between the electrons and the sample is captured by lenses and detected by a camera sensor in order to generate detailed images of the sample.

Ultrafast electron microscopes using these principles were first developed in the 2000’s and use a laser to generate pulsed beams of electrons. This technique greatly increases a microscope’s temporal resolution – its ability to measure and observe changes in a sample over time. In these ultrafast microscopes, instead of relying on the speed of a camera’s shutter to dictate image quality, the resolution of a transmission electron microscope is determined by the duration of electron pulses.

The faster the pulse, the better the image.

Ultrafast electron microscopes previously operated by emitting a train of electron pulses at speeds of a few attoseconds. An attosecond is one quintillionth of a second. Pulses at these speeds create a series of images, like frames in a movie – but scientists were still missing the reactions and changes in an electron that takes place in between those frames as it evolves in real time. In order to see an electron frozen in place, U of A researchers, for the first time, generated a single attosecond electron pulse, which is as fast as electrons moves, thereby enhancing the microscope’s temporal resolution, like a high-speed camera capturing movements that would otherwise be invisible.

Hassan and his colleagues based their work on the Nobel Prize-winning accomplishments of Pierre Agostini, Ferenc Krausz and Anne L’Huilliere, who won the Novel Prize in Physics in 2023 after generating the first extreme ultraviolet radiation pulse so short it could be measured in attoseconds.

Using that work as a steppingstone, U of A researchers developed a microscope in which a powerful laser is split and converted into two parts – a very fast electron pulse and two ultra-short light pulses. The first light pulse, known as the pump pulse, feeds energy into a sample and causes electrons to move or undergo other rapid changes. The second light pulse, also called the “optical gating pulse” acts like a gate by creating a brief window of time in which the gated, single attosecond electron pulse is generated. The speed of the gating pulse therefore dictates the resolution of the image. By carefully synchronizing the two pulses, researchers control when the electron pulses probe the sample to observe ultrafast processes at the atomic level.

“The improvement of the temporal resolution inside of electron microscopes has been long anticipated and the focus of many research groups – because we all want to see the electron motion,” Hassan said. “These movements happen in attoseconds. But now, for the first time, we are able to attain attosecond temporal resolution with our electron transmission microscope – and we coined it ‘attomicroscopy.’ For the first time, we can see pieces of the electron in motion.”
