WASHINGTON – The US Air Force will launch an environmental Impact review for a new military logistics project, in which the construction of two landing pillows on Johnston Island, a remote Atol in the Pacific Ocean, proposes.

De Pads would support the return of vehicles under the Rocket Cargo program of the Air Force, an initiative under the leadership of the Air Force Research Laboratory (AFFL) to use commercial rockets and return capsules for fast global freight release.

In a notification planned for publication in the Federal Register on 3 March, the Ministry of Air Force will formally announce its intention to prepare an environmental assessment. The assessment will evaluate the effects of building and operating the landing cushions on Johnston Atol, where a maximum of 10 recurring vehicle landings would be planned in four years every year. This test phase is intended to demonstrate and refine the possibilities of the Rocket Cargo program, which occurs to delivering critical supplies to each point on earth within a few hours.

The Environmental Review will collaborate with multiple federal agencies, including the Federal Aviation Administration (FAA), the US Fish and Wildlife Service and the National Wildlife Refuge System, given the status of the Atol as part of the Pacific Remote Islands National Wildlife Refuge. A draft of the assessment is expected in April, followed by a 30-day public commentary period, which offers stakeholders the opportunity to weigh the implications of the project.

Strategic foot in the Pacific Ocean

The Air Force identified Johnston Atoll as the optimal site after evaluating various remote locations controlled by the government, including Kwajalein Atoll, Midway Island and Wake Island. Johnston stood out as the only location that met all operational criteria: it is remote, secured, controlled by the US, accessible by air or sea and able to support the disguised removal of return vehicles. These requirements would join the Lancing and return permit requirements of the FAA, which prioritize public safety by obliging insulated landing zones for such activities.

Johnston Atoll, located about 700 nautical miles southwest of Hawaii, has a legendary military past. Since the 1930s it served as a hub for nuclear tests, rocket taf weather, storage of chemical weapons and even an air force anti-satellite weapon test. Turned out of use in 2004, the Atol was transferred to the National Wildlife Refuge System, although remains of its military infrastructure – including an airport – arrest.

Cargo -Terugkeercapsules

The Rocket Cargo program represents a daring step in military logistics, which uses the fast -growing commercial space sector to reduce the timelines of the delivery. Traditional air bridge methods, although reliable, can take days to move freight over continents. ADL, on the other hand, aimed at the use of space vehicles-such as return capsules that have fallen out during the flight from rockets to reach delivery on the same day. Companies such as inversion space, Buitenpost, Sierra space and Varda space develop such capsules. Launch providers such as SpaceX, Rocket Lab and Blue Origin hold Air Force contracts to show these options.

One scenario would be a rocket that is launched in a job, a truck with drawers goes back, and the vehicle slides back to earth and lands exactly on a designated site such as Johnston Island. In anticipation of the environmental approval, Air Force hopes this year to start testing the Johnston landing cushions to validate the feasibility and safety of technology.

Chicago – According to the Chicago Department of Public Health, the spread of the flu in Chicago has decreased to a moderate level.

Last Friday, the city agency reported that indicators of flu activity decreased at the end of February.

Moderate level of airway disorders

What we know:

The general level of acute activities of the airways in Chicago remained on moderate levels, according to the CDPH.

Covid-19 activity remained low.

RSV activity also remained low and fell in all surveillance indicators.

By the figures:

The number of visits to first aid and hospital admissions for the flu were still at increased levels for all age groups, but fell after the peak at the end of January.

The recordings to the ICU were also declining.

While COVID-19 Emergency visitors had risen for COVID-19 in children of 5 years and younger in the past two weeks, the total ICU recordings have been somewhat declined since last week.

Civil servants also noted that the CDC released its first estimates of the effectiveness of this season’s flu vaccine. The Federal Health Agency said that this season’s flu and COVID-19 vaccines were effective in preventing serious illness, including hospitalization, in the US

Nevertheless, flu and covid-19 vaccine recording in Chicago remains low. From mid-January, fewer than a quarter of the residents had received a flu shot and less than 12% had received a Covid-19 shot.

The Cataclysmic eruption of Mt. Vesuvius In 79 AD, researchers and historians have fascinated for centuries. Since the early 1700s, engineers have excavated the remains of the cities of Pompeii and Herculaneum, flash frozen in hills of volcanic axis.

And of all the stories that were drawn from the rubble, a 20 -year -old man whose brains who have melted in glass is the most mystify.

A piece of glass in the preserved skull of the Herculaneum -man was first discovered in 2020 and came from the back of the study that the temperature in the two doomed cities on some points during the cataclysm more than the Cataclysm surpassed.

Researchers were surprised because at that temperature brain material had to melt in Goo, not solidified in glass. Of the approximately 2,000 bodies that were excavated from the Vesuvian ruins, only this brain were stored in this way.

Thanks to a paper published earlier this year in the New England Journal of MedicineWe can even see what this glass -collected brain looks like.

A stable Pope Francis had a visit from the State Secretary of Vatican on Sunday while continuing his recovery of double pneumonia, the Vatican said, but again skipped his weekly afternoon blessing to prevent even a short public appearance from the hospital.

Instead, the Vatican spread a message from the pope in which he thanked his doctors for their care and benefactors for their prayers, and again prayed for peace in Ukraine and elsewhere.

“From here, war seems even more absurd,” Francis said in the message, which he has prepared of the Gemelli hospital in recent days, the Vatican said. Francis said he lived his hospitalization as an experience of deep solidarity with people who are sick and suffer everywhere,

“In my heart I feel the ‘blessing’ that is hidden in vulnerability, because it is exactly at these moments that we learn even more to trust the Lord,” Francis said in the text. “At the same time I thank God for giving me the chance to share the condition of so many sick and suffering people in body and mind.”

Signs indicate a recovery

It marked the third weekend in a row that Francis has canceled the Sunday appointment that the Angelus prayer delivered personally. He could have done this from his 10th floor Hospital suite in the Gemelli Hospital if he was good enough.

But many signs indicated that he was recovering and improved. “The night was quiet, the Pope still rests,” said the Vatican in his Sunday update.

Cardinal Pietro Parolin and his staff chef, Archbishop Edgar Pena Parra, called on the Pope on Sunday morning, their second visit since the hospital admission of Francis, according to the spokesperson for Vatican, Matteo Bruni. There were no details about what was discussed, but the mere visit suggested that the condition of Francis stabilized.

“The night was quiet, the Pope still rests,” said the Vatican in his Sunday early update.

He had no fever or signs of raised white blood cells, which would indicate that his body is still against infection.

Doctors on Saturday reported that Francis was in a stable state, without being critical. Their cheerful assessment came one day after a breathing crisis that led to him not being submitted invasive mechanical ventilation.

But the 88-year-old Pope had a “good reaction” in his gas exchange levels, even during the “long periods”, he was from the Ventilatormasker on Saturday and only used high-flow additional oxygen, said the Vatican.

The fact that Francis was able to use long -term oxygen with high current, without any significant effect on the oxygen levels in his blood, was a sign that his respiratory function was improving.

However, doctors were careful and kept his prognosis as guarded, which means that he was not in danger. He was eating and drinking and continued his breathing physiotherapy and spent 20 minutes in his private chapel in the hall on Saturday, the Vatican said.

The pope, who had removed part of one lung as a young man, has lung disease and was recorded on February 14 on 2 February after an attack by bronchitis deteriorated and turned into a complex pneumonia in both lungs.

Prayers continued to flow in

Francis’s hospitalization has come because the Vatican marks its holy year and attracts pilgrims from everywhere to Rome. They walk through the holy door in St. Peter’s Basilica and also make pilgrimages to the Hilltop Umbrian city of Assisi, to pray in the house of the namesake of Francis, St. Franciscus.

“Every day we pray for the Pope,” said the Reverend Jacinto Bento, a priest who visits Assisi on Saturday with a group of 30 anniversary pelgrims from the Azores Islands. “We are very sad for his situation.”

In a strange coincidence, Francis was supposed to have chaired Saturday about a holy annual audience in the auditorium of the Vatican for the staff of the Gemelli Hospital and other health workers. They came as planned and completed the pilgrimage, while Francis continued his recovery in the hospital.

“We thought we could meet him this morning in Paul VI Hall for the Jubilee catechesis, but he surprised us by coming to us,” said Monsignor Claudio Giuliodori, spiritual guide of the Catholic University of the Holy Heart, of which Gemelli is part.

Giovanni Frisullo, a gemelli neurologist, said that the atmosphere in Gemelli was one of tension and prayer. “There is a situation of waiting but also of hope,” he said.

The Blue Ghost Lander from Firefly Aerospace may have just been touched on the moon, but it already shines spectacular views of the earth from the moon surface after a historic landing today (March 2).

These incredible images of the moon taken by the private Blue Ghost Lander were shared by his builder, Firefly Aerospace, only a few hours after the moon landing.

Blue Ghost landed in the Mare Crision (the Sea of ​​Crises), after agreeing two maneuvers of hazards and to reach a precision landing within 328 feet (100 meters) of his target zone near the volcanic feature Mons Latreille.

“This is an incredibly challenging technical achievement to pull out, to land, everything on the surface of the moon,” said Joel Kearns, deputy -associate manager for exploration in the NASA Science Mission Directorate during the press conference.

Shortly after the landing, Firefly Aerospace revealed this image of the surface of the moon, it was obtained the first image by the Blue Ghost Lunar Lander. The images were released by the S-Band images of Blue Ghost, with X-band images with a higher resolution expected in the coming hours when the Lander uses his most important antenna.

Firefly chose to refrain from a live video stream of the Landing of the Blue Ghost to release the communication band width for telemetry and for various instruments that were in action during the descent, including a critical danger system that the Lander helps at least two potentially dangerous rock blokes, Fireflokkken, Fireflokkken, Rotsblokken, Rotsblokken, Rotsblokken, Rotsblokken, Rotsblokken, Rotsblokken, Rotsblokken Spelcraft program director.

Danish archaeologists have discovered a 4,000-year-old circle of wooden posts that they say can be linked to the world-famous Stonehenge in Great Britain.

The 45 wooden pieces of the Neolithic era, in a circle with a diameter of approximately 30 meters (100 feet), were found during work in a residential area in the north -western city of Aars. The piles are about two meters apart.

The circle “points to a strong bond with the British Henge world,” she added.

The two circles of stones in Stonehenge in South England are assumed between 3100 BC. And 1600 BC to have been built.

The Danish archaeologists are now trying to find whether there is an inner circle on the Aars site.

Wahlin said that some wooden circles, considered part of the sun worship, were found on the Danish island of Bornholm.

She added that the circle was in ass “the first of this larger type that we can investigate”.

Archaeologists found an early Bronze Age for the first time (1700-1500 BC) settlement on the construction site with a chieftains grave and a bronze sword, Wahlin said.

“When I and my colleague opened a new part of the excavation, the expected house and what fence soon turned out to be the entrance of a very well -planned, somewhat oval structure,” she added.

The wooden circle is estimated on the date of approximately 2000 BC, but Wahlin said that the team had started detailed work on Monday to definitively identify its age and position.

The archaeologists are now looking for “ritual deposits” such as Flint Arrowheads and daygers as part of an important sample exercise on the site.

Wahlin said the following searches would try to find whether there were connections between the region and other peoples, such as those who built Stonehenge. She said that the influence of other regions could be seen in the pottery and the graves that had been found.

The world’s first private space distance built to visit an asteroid, slowly tumbling in space and the prospects are terrible.

The spacecraft, called Odin, launched a SpaceX rocket (26 February) on Wednesday on top of a mission to fly through the small Asteroid 2022 OB5 for Astroforge, a company that eventually wants to get the nearby Space Rock. But only a few hours after the launch, Astroforge broke with the probe. The last contact was 20 hours after the launch.

In 2023, neurologists in a memory clinic in China diagnosed a 19-year-old with what they thought it was Alzheimer’s diseaseWhich makes him the youngest person ever to get the condition in the world.

The male teenager started to take memory around the age of 17, and the cognitive losses only deteriorated over the years.

The image of the patient’s brains showed shrinkage in the hippocampus, which is involved in the memory, and had his cerebrospinal liquid shifted to common markers of this most common form of dementia.

Alzheimer’s disease (AD) is often seen as the ailment of an old person, and yet early cases, including patients under the age of 65, good for a maximum of 10 percent of all diagnoses.

Almost all patients under the age of 30 can explain their Alzheimer’s by pathological gene mutations, so that they are placed in the Family Alzheimer’s Disease (FAD) category. The younger a person is when they get a diagnosis, the greater the chance that it is the result of a defective gene that they have inherited.

Nevertheless, researchers from Capital Medical University in Beijing could find neither of the usual mutations responsible for the early memory loss, nor any suspicious genes when they performed a genome -wide search.

Before this diagnosis in China, the youngest patient with Alzheimer’s was 21 years old. They wore the PSEN1 gene mutation, so that abnormal proteins accumulate in the brain, causing lumps toxic plaques to be formed, a common characteristic of Alzheimer’s.

Cases like those in China form something of a mystery. None of the 19-year-old family had a history of Alzheimer’s or dementia, making it difficult to categorize as a craze, but the teenager had no other diseases, infections or head trauma that could also explain his sudden cognitive decline.

Two years before he was referred to the memory clinic, the teenage patient began to struggle to concentrate in class. Reading also became difficult and his short -term memory fell. Often he could not remember any events from the day before, and he was always misplaced.

Eventually the cognitive decline became so bad, the young man could not finish high school, although he could still live independently.

A year after he had been referred to the memory clinic, he showed losses in immediate recall, discount delay after three minutes and after 30 minutes of long -term recall.

The full memorial score of the patient was 82 percent lower than that of peers of his own age, while his immediate memorial score was 87 percent lower.

Long-term follow-up is needed to support the diagnosis of the young man, but his medical team said the moment the patient “changed our understanding of the typical age of the beginning of AD”.

“The patient had a very early advertisement without clear pathogenic mutations,” Neurologist Jianping Jia and colleagues Wrote in their research, “which suggests that his pathogenesis still has to be investigated.”

The Case Study, published in February 2023, only shows that Alzheimer’s follows no route and is much more complex than we thought, coming up via countless roads with different effects.

In a statement to the South China Morning Post, the neurologists describing the patient’s case argued that future studies should concentrate on cases of early starting to further improve our understanding of memory loss.

“Exploring the mysteries of young people with Alzheimer’s disease can become one of the most challenging scientific questions of the future,” they said.

The study was published in the Journal of Alzheimer’s Disease.
