American scientists stitched together 370 separate images and observations of the center of our galaxy in different spectra (mainly X-ray), obtaining an image of unprecedented clarity and completeness. An unknown energy source is visible in this mosaic, the Chandra X-ray Observatory press service writes. The center of the Galaxy is relatively close to us, […]

For the first time, the hydrogen corona of Mars is shown: photos came from the probe الأمل
The probe الأمل (“Hope”) of the first Arab interplanetary mission transmitted data to Earth, according to which scientists have collected the first and almost complete image of the exosphere of Mars – the so-called corona. The press service of the Hope Mars Mission writes about this. On May 10, from an orbit of 20,000 […]
CoronaVac vaccine against the “Amazon” strain of coronavirus: results from Brazil
The effectiveness of the CoronaVac vaccine from Sinovaс Biotech in the country affected by the “Brazilian” strain of coronavirus after two doses reaches only 42% protection against COVID-19 with symptoms. We are talking about the effectiveness in the elderly from 70 years and older, write in the preprint of the study on medRxiv. For […]
Previously unknown “bridges” of dark matter between galaxies discovered – research
An international group of astrophysicists has developed a new model of the distribution of dark matter in the local Universe using machine learning – and discovered previously unknown filamentous structures-bridges between galaxies in it. They reported this in the Astrophysical Journal, writes SciTechDaily. According to the latest data, the observable Universe consists of 4.9% […]
For the first time in history. Blind 40-year-old man partially restored his sight – helped by genetics
For the first time in the history of medicine, genetic engineering was used to restore partial vision in a blind person: by “correcting” the ganglion cells of the retina, American scientists made them photosensitive again. The research is published in the journal Nature. A 58-year-old man went blind at the age of 18 as […]
Chinese probe Tianwen-1 sent first footage from the surface of Mars – photo
The Chinese probe Tianwen-1 has sent its first first photographs taken on the surface of Mars. This was reported by the press service of the China National Space Administration. The pictures show the landing platform and the ladder of the Zhu Rong rover – it is reported that the exit ramp mechanism is deployed […]
Geophysicists have shown a quasicrystal formed by the explosion of the Trinity atomic bomb – photo
At the former nuclear test site in New Mexico, quasicrystals were discovered, which formed on July 16, 1945 after the first ever test of the Trinity atomic bomb. Quartz, feldspar, soil and other materials in the place of detonation melted and under shock and high pressure conditions formed vitreous red trinitite, writes Nature, citing research […]
Scientists have checked the feces and mouths of bats in the south of the Russian Federation. Found “relatives” of SARS-CoV-2
Potential pathogens similar to the pandemic coronavirus are circulating among bats in the southern Krasnodar Territory of Russia near Ukraine. This is the conclusion reached by the scientists of the Center. Hamaleas in the Russian Federation by checking the feces and swabs from the oral cavity of the large (R. ferrumequinum) and small (R. hipposideros) […]
A cosmic photon with a monstrous energy registered: 1.4 quadrillion electron volts
The Large Alpine Air Showers Observatory in Sichuan in southwestern China reported a photon with the highest energy ever observed, 1.4 petaelectronvolts (1.4 x 1015 eV). Such a discovery could lead to a serious change in the established ideas about our Galaxy, writes the press service of LHAASO. The results of the study will also […]
The genomes of the “Spanish” flu virus have been deciphered: evidence of its evolution has been found
A century later, an international team of scientists deciphered the genetic code of the Spanish flu virus that led to the pandemic. Samples for analysis were taken from the lung tissue of two German soldiers, 17 and 18 years old, who died on June 27, 1918 from the “Spanish flu” in Berlin, and a 17-year-old […]
