00:00In Morocco, the shortage of methadone threatens the lives of patients living with HIV.
00:06This shortage announced by the Ministry of Health is due to a delay in supplies.
00:12Several health-related associations are working on this issue,
00:16including the Ministry of Health, the Ministry of Health of Morocco,
00:20the Ministry of Health of Morocco and the Ministry of Health of Morocco.
00:25The Ministry of Health is due to a delay in supplies.
00:28Several associations involved in public health last Thursday issued an alert
00:33in the face of the imminent exhaustion of the stock of this essential drug
00:37in the treatment of opioid addiction.
00:40The Information Express website reported that these same associations
00:44warn that this situation could have disastrous repercussions
00:48on the health of concerned patients,
00:50particularly those living with HIV and those with hepatitis B and C.
00:55This is not the first time that the shortage of drugs has threatened the health of patients.
01:00Concerned by the outbreak of this crisis,
01:02the associations strongly criticize the solutions advanced by the Ministry,
01:06including the systematic and automatic reduction of methadone doses
01:10for all patients, including those living with HIV,
01:13patients with hepatitis and people suffering from tuberculosis.
01:17They believe that this approach, far from solving the problem,
01:20risks aggravating the situation
01:22by provoking disastrous medical and social consequences.
01:26What if dogs were part of the secret of human obesity?
01:30The Parisien looked into the study published last Thursday
01:33in the journal Science, on labradors.
01:36In this sense, researchers have identified a gene
01:39that could influence this disease in humans.
01:41According to this article, the dog is not only the faithful friend of man,
01:45but also a relevant model to study human obesity.
01:49The originality of this study lies, according to Professor Philippe Froegel,
01:53in his methodology.
01:54Froegel explained that so far,
01:56they had already discovered that 20% of labradors
01:59presented mutations in a gene of human obesity called POMC,
02:03which controls satiety.
02:05Researchers took samples of saliva on labradors
02:08in order to obtain their DNA.
02:10The comparison of the DNA of smaller and larger dogs
02:13has made it possible to identify genes
02:15influencing the body weight of dogs.
02:17This discovery is all the more surprising,
02:19since researchers have found
02:21that this gene is also present in humans.
02:24These results highlight the interest in using
02:26non-traditional animal models
02:28to study complex diseases.
02:30They also highlight the potential of this gene
02:33as a target for future research
02:35on the obesity of all species.
02:37Another discovery made a lot of noise
02:39in the scientific community.
02:41A study published in the journal Nature
02:43showed a discovery of bone tools
02:45dating from 1.5 million years ago.
02:47However, until then,
02:49it was thought that this practice had begun
02:51at least a million years later.
02:53According to the Science and Life website,
02:55a team of archaeologists discovered in the gorges of Olduvay,
02:57in Tanzania,
02:58tools made from animal bones
03:00by the people called Old Owen,
03:02dating from 1.5 million years ago.
03:05This people of the homo habilis genus
03:07was already known for its stone tool making
03:101 million years ago.
03:12This discovery suggests that
03:14the first men considerably expanded
03:16their technological choices,
03:18which were until now limited,
03:20to stone artifact production.
03:22This suggests progress in cognitive skills
03:24and mental models of these hominids,
03:26who understood how to transfer
03:28the technological innovations
03:30of stone carving
03:32to the production of bone tools.
03:34Paleontological fact,
03:36an incredible discovery
03:38on an ancient predator.
03:40Geolia langshengi, a giant scorpion,
03:42which lived about 125 million years ago
03:44next to dinosaurs.
03:46This is what the Science Post website
03:48related to.
03:50Found in the formation of Yinshan,
03:52an exceptional fossil site
03:54of the lower crestacean,
03:56located in China,
03:58this fossil is the first terrestrial scorpion
04:00of the Mesozoic era discovered in the country.
04:02This rare and precious discovery
04:04opens a new window
04:06to discover other fossils.
04:08Terrestrial scorpion fossils
04:10are particularly rare,
04:12especially when it comes
04:14to specimens dating from
04:16between 250 and 66 million years ago.
04:18Most fossilized scorpions
04:20of this period are preserved in amber,
04:22which makes the discovery
04:24of Geolia langshengi
04:26even more exceptional.
04:28This fossil was discovered
04:30in the Geol biotope,
04:32a famous region for the extraordinary
04:34that the region housed a rich and complex ecosystem,
04:36populated by dinosaurs,
04:38primitive birds, mammals,
04:40frogs and insects.
04:42With its imposing size
04:44and its physical characteristics adapted to hunting,
04:46this scorpion would have played
04:48an essential role in the food chain.
04:50Light could now
04:52behave like a fluid and a solid.
04:54This is what is called a super solid.
04:56Italian researchers have succeeded
04:58in transforming light
05:00into a new state of matter
05:02with the properties of a solid and a fluid.
05:04A super solid therefore has
05:06an orderly crystalline structure
05:08like a solid, but it can also have
05:10a capacity to flow without resistance
05:12like a fluid, i.e.
05:14with zero viscosity.
05:16These priorities considered as opposed
05:18in classical physics are understood
05:20only by the principles of quantum mechanics.
05:22The GEO website highlighted
05:24this discovery, which opens
05:26new perspectives to understand
05:28quantum phenomena.
05:30The examples of super solids created
05:32in laboratories have been realized
05:34in controlled conditions,
05:36often using atoms cooled
05:38at extremely low temperatures.
05:40It is therefore in conditions
05:42close to absolute zero,
05:44i.e. less than 173.15°C,
05:46that quantum phenomena
05:48appear. But to transform
05:50light into super solids,
05:52the scientists of the National Council
05:54of Research in Italy
05:56tried a different approach.
05:58Using ultra-cold atoms,
06:00the scientists used a laser
06:02projected on a semiconductor material
06:04and light in front of a solid.
06:06While quantum physics continues
06:08to evolve, the creation of a super solid
06:10based on light represents
06:12the beginning of a series of
06:14exciting future research.
06:16Let's leave Earth and head for space
06:18to close this press release.
06:20According to the private company
06:22Intuitive Machines,
06:24commissioned by the American Space Agency
06:26for Space Research and Technology on the Moon,
06:28the Athena probe does not have
06:30the correct orientation after
06:32its landing. According to Le Monde,
06:34Intuitive Machines announced
06:36last Thursday that the machine,
06:38which had landed a little earlier
06:40on the Moon, had probably not landed
06:42vertically as expected.
06:44The precise location of Athena's landing
06:46and its operational state are still
06:48being evaluated.
06:50Intuitive Machines' boss
06:52specified that the teams
06:54had landed in the right place,
06:56an area about 160 km
06:58from the south pole of the Moon.
07:00This is a success because
07:02no machine had so far
07:04approached the pole.
07:06However, the fact that the device
07:08could be tilted could lead
07:10to a lower energy production,
07:12which could have limited
07:14the experiments and demonstrations
07:16that the company and NASA
07:18aimed to carry out.
07:20We reach the end of this press release.
07:22Here's what you need to know
07:24about Intuitive Machines on Median.
