Doctors usually recommend several measures for stroke survivors, including exercising that require a walker or a cane, in addition to a leg crutch that maintains the body’s balance and stability during the walking retraining.

A team including researchers from Spain’s Universidad de Alcalá (UAH), New Jersey City University, and the American University of Cairo (AUH), discovered that ancient Egyptians had applied similar measures to rehabilitate stroke patients. The discovery involved an ancient Egyptian mummy from the 25th Dynasty, unearthed by the Spanish-Egyptian mission working at the Dra Abu el-Naga necropolis located on the West Bank of the Nile, in Luxor (southern Egypt).

The mummy labeled “Ind-6833” is one of 17 embalmed mummies at the tomb chapel of Hery (TT 12) of the early Eighteenth Dynasty (c. 1550-1292 BC).

After X-rays and examinations, archeologists found the mummy marks the oldest leg injury in a stroke patient ever, and unveils unfamiliar measures taken at the time to cope with the injury that caused hemiplegia in the left part of the body.

In the study published in the latest issue of the journal World Neurosurgery, the researchers said their findings show that the measures adopted to treat patients after a stroke are similar to the recommendations that physicians currently recommend in such cases. The archeologists found that canes and crutches were used by the ancient Egyptians to support the affected leg.

According to the team, the body belonged to a woman, between 25 and 40 years of age. The type of mummification was of a high level, with excerebration and evisceration carefully performed. She suffered a stroke late in life and lived with the results for several years.

“Ancient Egyptians were among the first people to apply medical interventions. The new discovery is not surprising, as ancient Egyptians were the first to provide a detailed brain description, according to the Edwin Smith Papyrus,” Bassem al-Shamaa, historian and Egyptologist, said on the new discovery.

“When you examine a man with a wide wound reaching the skull bones and exposing the brain, you could sense the wound with your hand and feel that the surface of the brain in the bottom of the wound is like a slag on the surface of fused copper inside a melting pot. You could also notice pulses that resemble the pulses you feel when you place your hand on the head of a newborn whose skull bones are still not fused,” he explained.

“These findings deny what some claimed about a regression Ancient Egypt witnessed under the rule of the 25th Dynasty during the Nubian occupation. The new discovery should motivate researchers to restudy that period, whose excavations have always been subject to religious and ideological interpretations. The new discovery suggests that period had probably witnessed medical procedures and interventions,” he told Asharq Al-Awsat”.

Japan Sees Bright Future for Ultra-Thin, Flexible Solar Panels

Japan is heavily investing in a new kind of ultra-thin, flexible solar panel that it hopes will help it meet renewable energy goals while challenging China's dominance of the sector.

Pliable perovskite panels are perfect for mountainous Japan, with its shortage of flat plots for traditional solar farms. And a key component of the panels is iodine, something Japan produces more of than any country but Chile, reported AFP.

The push faces some obstacles: perovskite panels contain toxic lead, and, for now, produce less power and have shorter lifespans than their silicon counterparts.

Still, with a goal of net-zero by 2050 and a desire to break China's solar supremacy, perovskite cells are "our best card to achieve both decarbonization and industrial competitiveness," minister of industry Yoji Muto said in November.

The government is offering generous incentives to get industry on board, including a 157-billion-yen ($1 billion) subsidy to plastic maker Sekisui Chemical for a factory to produce enough perovskite solar panels to generate 100 megawatts by 2027, enough to power 30,000 households.

By 2040, Japan wants to install enough perovskite panels to generate 20 gigawatts of electricity, equivalent to adding about 20 nuclear reactors.

That should help Japan's target to have renewable energy cover up to 50 percent of electricity demand by 2040.

- Breaking the silicon ceiling -

The nation is looking to solar power, including perovskite and silicon-based solar cells, to cover up to 29 percent of all electricity demand by that time, a sharp rise from 9.8 percent in 2023.

"To increase the amount of renewable energy and achieve carbon neutrality, I think we will have to mobilize all the technologies available," said Hiroshi Segawa, a specialist in next-generation solar technology at the University of Tokyo.

"Perovskite solar panels can be built domestically, from the raw materials to production to installation. In that sense, they could significantly contribute to things like energy security and economic security," he told AFP.

Tokyo wants to avoid a repeat of the past boom and bust of the Japanese solar business.

In the early 2000s, Japanese-made silicon solar panels accounted for almost half the global market.

Now, China controls more than 80 percent of the global solar supply chain, from the production of key raw material to assembling modules.

Silicon solar panels are made of thin wafers that are processed into cells that generate electricity.

They must be protected by reinforced glass sheets and metal frames, making the final products heavy and cumbersome.

Perovskite solar cells, however, are created by printing or painting ingredients such as iodine and lead onto surfaces like film or sheet glass.

The final product can be just a millimeter thick and a tenth the weight of a conventional silicon solar cell.

Perovskite panels' malleability means they can be installed on uneven and curved surfaces, a key feature in Japan, where 70 percent of the country is mountainous.

- Generating where power is used -

The panels are already being incorporated into several projects, including a 46-storey Tokyo building to be completed by 2028.

The southwestern city of Fukuoka has also said it wants to cover a domed baseball stadium with perovskite panels.

And major electronics brand Panasonic is working on integrating perovskite into windowpanes.

"What if all of these windows had solar cells integrated in them?" said Yukihiro Kaneko, general manager of Panasonic's perovskite PV development department, gesturing to the glass-covered high-rise buildings surrounding the firm's Tokyo office.

That would allow power to be generated where it is used, and reduce the burden on the national grid, Kaneko added.

For all the enthusiasm, perovskite panels remain far from mass production.

They are less efficient than their silicon counterparts, and have a lifespan of just a decade, compared to 30 years for conventional units.

The toxic lead they contain also means they need careful disposal after use.

However, the technology is advancing fast. Some prototypes can perform nearly as powerfully as silicon panels and their durability is expected to reach 20 years soon.

University professor Segawa believes Japan could have a capacity of 40 gigawatts from perovskite by 2040, while the technology could also speed up renewable uptake elsewhere.

"We should not think of it as either silicon or perovskite. We should look at how we can maximize our ability to utilize renewable energy," Segawa said.

"If Japan could show a good model, I think it can be brought overseas."
