China has become a major intellectual property (IP) power and important pole in the world's innovation landscape after 30 years in the Patent Cooperation Treaty (PCT), Foreign Ministry spokesperson Wang Wenbin said at a press briefing on Wednesday. 

"China attaches great importance to international patent cooperation and intellectual property protection," Wang said, noting that the number of international patent applications by Chinese applicants through the PCT has ranked first in the world for four consecutive years.

According to Wang, in the 30 years since joining the PCT, China has actively participated in the revision and improvement of international rules such as those of the PCT and continuously improved the domestic IP legal system, while carrying out fruitful cooperation with the World Intellectual Property Organization (WIPO). 

"IP is an important source of support for innovative development. With the support of patented technology, China has continuously improved its IP quality and efficiency to accelerate innovation," Wang noted. 

He gave the example of China's 126,400 global patent applications for solar cells, which ranked first in the world. China's leading new-energy vehicle producers have more than 100,000 valid global patents, leading in the green and low-carbon industry.

China continues to expand the opening-up of the IP field to create a market-oriented, legal and international first-class business environment, according to Wang. 

A total of 115 the Belt and Road Initiative (BRI) partner countries have applied for 253,000 patents in China during the past 10 years, with an average annual growth rate of 5.4 percent. As of the end of 2022, the number of valid foreign invention patents in China reached 861,000, a year-on-year increase of 4.5 percent, which fully reflects the recognition of foreign-invested enterprises in China's IP protection.

China will continue to adhere to the principles of openness, inclusiveness, balance and universal benefit, strengthen international exchanges and cooperation with other countries in the field of IP, promote the development of global IP governance in a more fair and reasonable manner, and allow innovation to benefit more people of all countries, Wang said. 

According to the Global Innovation Index (GII) 2023 released by the WIPO in September, China ranked 12th globally, with six indicators ranking first in the world. Three science and technology clusters - Shenzhen-Hong Kong-Guangzhou, Beijing and Shanghai-Suzhou - were among the world's top five. 

In addition, the GII identified 24 science and technology clusters in China, up from 21 in 2022, as the country is now home to the greatest number of science and technology clusters, said the WIPO.

The death toll from a strong earthquake that struck Morocco Friday night has risen to 820, said the country's Interior Ministry on Saturday.

The earthquake has also injured at least 672, according to the latest update from the ministry.

A 6.8-magnitude earthquake hit Morocco Friday at 11:11 p.m. local time (2211 GMT) at a depth of 18.5 km, said the U.S. Geological Survey.

The epicenter of the earthquake was near the town of Ighil in Al Haouz Province, some 70 km southwest of Marrakesh.

The earthquake was felt in many cities across Morocco, including Rabat and Casablanca. Many houses collapsed in the cities of Taroudant and Marrakesh, local media reported.

The earthquake damaged many buildings in the old city of Marrakesh, the nearest big city to the epicenter, and many residents had to spend the night in the open space for fear of potential aftershocks, said Zhang Kai, an overseas Chinese living in Marrakesh.

Xinhua correspondents at Ouarzazate, about 190 kilometers southeast of Marrakesh, saw residents taking shelter in an open space after the earthquake.

"There have been earthquakes before, but none of them were as strong as this one," said a resident in Ouarzazate who requires anonymity.

On the way from Ouarzazate to the epicenter, rocks and rubbles from the mountains and buildings were seen scattered along the road.

Rescuers have been sent to the quake-hit areas to search for survivors, local media reported.

As if air travel weren’t annoying enough, new research suggests that global warming could force planes to carry fewer passengers to get off the ground. While a little more legroom might sound good, it could make flying more expensive.

Researchers examined the impact of rising temperatures on five types of commercial planes flying out of 19 of the world’s busiest airports. In the coming decades, an average of 10 to 30 percent of flights that take off during the hottest time of day could face weight restrictions.

That’s because warmer air particles are more spread out, generating less lift under a plane’s wings as it goes down the runway. So a plane must be lighter to take off. In some cases, a Boeing 737-800 would have to jettison more than 700 pounds — several passengers’ worth of weight — the researchers report online July 13 in Climatic Change.

ORLANDO, Fla. — Interbreeding with Neandertals restored some genetic heirlooms that modern humans left behind in the ancient exodus from Africa, new research suggests.

Those heirlooms are versions of genes, or alleles, that were present in humans’ and Neandertals’ shared ancestors. Neandertals carried many of those old alleles, passing them along generation after generation, while developing their own versions of other genes. A small number of humans left Africa around 100,000 years ago and settled in Asia and Europe. These migrants “lost” the ancestral alleles.
But when the migrants or their descendants interbred with Neandertals, Eurasians reinherited the ancestral heirlooms along with Neandertal DNA, John “Tony” Capra reported October 20 at the annual meeting of the American Society of Human Genetics.

Present-day Europeans have more than 47,000 of these reintroduced ancestral alleles, and East Asians — who have more Neandertal ancestry than Europeans (SN Online: 2/12/15) — carry more than 56,000, said Capra, an evolutionary geneticist at Vanderbilt University in Nashville.

Capra and others have evidence that Neandertal versions of genes make humans more prone to some diseases (SN: 3/5/16, p. 18). Of the thousands of ancestral variants reintroduced into modern humans, only 41 have been linked in genetic studies to diseases, such as skin conditions and neurological and psychiatric disorders, he said. The researchers can’t tell for sure whether the effect is from the ancestral variant or neighboring Neandertal DNA. Capra and Vanderbilt colleague Corinne Simonti’s analyses indicate that the Neandertal DNA is more likely to blame. Many of the ancestral alleles are still present in modern-day Africans, Capra said, “so they’re unlikely to be very, very bad.”
