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