00:00Hello and welcome to your press release on Média1.
00:14We start with Geo.
00:16The magazine focuses on the construction of Xinhua,
00:19the world's first hybrid nuclear power plant
00:22that will soon be launched in China.
00:24Indeed, China is about to start the construction
00:27of this first fusion-fission hybrid power plant.
00:30It could power the power grid by the end of the decade
00:34at a continuous 100 MW.
00:36According to Interesting Engineering,
00:39the reactor, named Xinhua,
00:40worth 20 billion yuan,
00:42or 2.76 billion dollars,
00:45is currently subject to a public appeal
00:47based on the study of its environmental impact,
00:50revealed Geo.
00:51Xinhua means spark
00:53and would come from Mao Zedong's quote,
00:55a single spark can start a prairie fire.
00:58It is a collaboration between China Nuclear Industry,
01:0223 Construction Corporation
01:04and Lianovation Superconductor,
01:07a public company.
01:08The facility will be built on the scientific site Yaohu,
01:12in the province of Jiangxi,
01:13in the center of China,
01:14said the magazine.
01:16According to an agreement signed in 2023 between the manufacturers,
01:19the reactor should reach a Coulomb factor of more than 30,
01:22the Coulomb factor being an energy gain factor
01:25that measures the relationship between the thermal power produced
01:28and the input power used to heat the plasma
01:31during a fusion reaction,
01:33observed Geo.
01:34And we continue with Futuration.
01:35According to the portal of information,
01:37modern humans would not be from a single and unique lineage.
01:41According to the site,
01:42a new study reveals that the human lineage
01:44would be much more complex than we thought.
01:46Our genome indeed presents traces of two ancestral populations
01:50that would separate very early before fusing again.
01:53Results published in the journal Nature Genetics
01:56suggest a much more complex story
01:59on the basis of genetic data.
02:01A team of researchers shows that Homo sapiens
02:03would be the result of a separation between two lineages
02:06more than a million years ago,
02:07then a fusion between these two branches
02:09having evolved independently,
02:12affirms the portal of information.
02:13Researchers have thus analyzed the DNA of different current populations,
02:17Africa, Asia, Europe and America,
02:19having identified the traces of two ancestral populations.
02:23Results have shown that immediately after the separation of these two groups,
02:27one of them suffered what we call a stranglehold,
02:30that is to say a severe reduction in the number of individuals
02:33and therefore in genetic diversity.
02:35This population then stifled progressively for a million years,
02:39calculates the portal of information.
02:41It is the one that currently contributes to 80% of our genetic material.
02:45Also, on the basis of archaeological data,
02:48researchers advance that it could be Homo erectus
02:51and Homo heidelbergensis.
02:53These two species did indeed live in Africa at the same time,
02:56signs future science.
02:58Place now to Al-Ahram.
02:59The newspaper reports a stunning discovery,
03:02the tomb of a military commander of Ramses III, At-Tel-Raut.
03:06In the same region, the Egyptian archaeological mission
03:09has also updated the collective tombs dating from the Greco-Roman era,
03:13the tomb of a high military commander dating from the reign of King Ramses III,
03:16as well as a series of collective tombs in the region of Masrouta,
03:20in the governorate of Ismailia,
03:22announced by the Supreme Council of the Antiquities.
03:24Among the objects found reports the newspaper,
03:27tips of bronze arrows and remains of a ceremonial scepter,
03:31witnessing the high military rank of the Egyptian sovereign.
03:34The tomb, built of brick, of raw earth,
03:36contains a main funeral chamber and three annexed rooms.
03:39The inner walls are covered with white plaster,
03:41describes the daily life.
03:43Among the other precious objects discovered,
03:45archaeologists found vases in albatross decorated with inscriptions
03:48with traces of paint,
03:50as well as two cartridges bearing the name of King Horemeb,
03:53one of the most famous sovereign warriors of the 18th dynasty.
03:56In addition, a golden ring bearing the cartridge of King Ramses III,
04:00a collection of pearls and stones of different shapes and colors,
04:04as well as a small box in ivory,
04:06were found, precise al-Haram.
04:08In the news also,
04:09the UN of Science and the Future,
04:11where supersonic winds at 33,000 kmh
04:14detected on a giant exoplanet,
04:16thanks to an ultra-precise spectrograph
04:18installed on the Very Large Telescope
04:21of the European Observatory in Chile.
04:24Dazed, disheveled,
04:26adjectives are sought to qualify the winds
04:28blowing in the high atmosphere of the planet WASP-127b,
04:3333,000 kmh according to a study published
04:35in the journal Astronomy and Astrophysics.
04:38It is 100 times stronger than the most violent terrestrial winds.
04:41The exoplanet even breaks the record of the solar system
04:45recorded on Neptune at 1,800 kmh,
04:48finally, it is even faster than the speed of blood on the planet,
04:51estimated at 10,800 kmh
04:53than between 1,240 kmh on Earth.
04:56This discovery, declared monthly,
04:58has been made possible
05:00thanks to the VLT,
05:01the Very Large Telescope
05:03of the European Observatory in Australia,
05:05ESO in Chile,
05:06and more particularly
05:07to its high-resolution spectrograph,
05:09CRERES+, mounted on the telescope.
05:12The CRERES+, analyzes infrared light
05:14from planets or galaxies
05:16and decomposes it into these different wavelengths,
05:19like a prism,
05:20separates light into a rainbow.
05:22This is how the authors of the study
05:24were able to clearly identify
05:25the presence of absorption rays
05:27characteristic of water
05:29and carbon monoxide.
05:30But in addition to their presence,
05:32they were able to measure their movement.
05:34Congratulations, science and future!
05:36And finally for Clore, your press release,
05:38an English cave reveals an episode of ritual cannibalism
05:41in the Bronze Age,
05:42reports the magazine
05:43Pour la Science.
05:45Bones found in the grotto
05:46of Charterhouse Warren in England
05:48attest to a massacre followed by ritual cannibalism
05:51that occurred more than 2,000 years before our era.
05:54The diggers have collected more than 3,000 human bones.
05:57However, as they only dug half of the well,
05:59they estimate that they have brought to light
06:01only 50% of the remains,
06:02precisely the monthly.
06:04Thus, at least 30 of these men,
06:06women and children,
06:07and undoubtedly many more,
06:08were put to death with masses,
06:10then systematically dismembered
06:12and stripped of their flesh
06:13using butcher techniques.
06:15Once this flesh consumption was completed,
06:18the remains were thrown away
06:20in a well, probably,
06:21whose well found the monthly.
06:23The exploitation of many individuals and animals
06:26represented by the assembly
06:27suggests a feast
06:29to which several hundred people participated.
06:32We do not know if within the population
06:33a selection took place
06:35and some individuals were spared.
06:37Young women are aged to reproduce, for example.
06:40We can also wonder
06:41if these violent killings
06:42and these spectacular dismemberments
06:44were more important during the feast
06:46than the flesh consumption.
06:48Anyway,
06:49it is clear that a large social event
06:51was carefully organized,
06:53marked by the annihilation
06:55of an entire human group,
06:56relic for science.
06:58Thus, we come to the end
06:59of your press release on Média1.
07:01Good follow-up of the programs on our antennas.
