The first South Korean lunar probe sent the first photo of the Earth and the Moon

The Danuri probe, which became South Korea's first lunar probe, sent back to Earth the first image of the Earth and the Moon. Thus, engineers confirmed the functionality of the camera, which examined the far side of the Moon from an unusual distance, according to the website of the Korean Astronomy and Space Science Institute… Continue reading The first South Korean lunar probe sent the first photo of the Earth and the Moon

South Korea's first lunar probe, Danuri, launched aboard Falcon 9

The Falcon 9 launch vehicle carrying the Danuri lunar probe, South Korea's first interplanetary spacecraft, launched from Cape Canaveral. The probe will operate in a lunar polar orbit for at least a year, studying the composition and structure of the Moon's surface, and will also look for ice deposits in the Moon's polar craters. The… Continue reading South Korea's first lunar probe, Danuri, launched aboard Falcon 9

Dogs have been edited again in South Korea. Now – to strengthen Labrador hips

Two genetically modified Labradors with a reduced risk of developing hip dysplasia have been born in South Korea. This is the result of an experiment by geneticists who combined two methods: cloning and primed genome editing. They hope that in this way it will be possible to rid purebred animals of the mutations that have… Continue reading Dogs have been edited again in South Korea. Now – to strengthen Labrador hips

Archaeologists have discovered Britain's oldest millet

Archaeologists have discovered the remains of a building and a pit near Norwich, England, built by people in the late Bronze Age. In addition to charcoal and several artifacts, scientists found the remains of cultivated plants: flax, wheat, barley and millet. Radiocarbon dating has shown that it is the oldest millet in Britain, grown around… Continue reading Archaeologists have discovered Britain's oldest millet

Photonic quantum engine efficiency approaches one hundred percent

Korean physicists have produced the world's first quantum engine using the quantum coherence of a reservoir. To do this, they used a photon gas as a working fluid in a cavity through which super-emitting atoms fly. In this way they were able to achieve 98 percent engine efficiency. The study was published in Nature Photonics.… Continue reading Photonic quantum engine efficiency approaches one hundred percent

The Himalayan bear was the result of hybridization between northern and southern bears

Geneticists have examined the nuclear DNA of six species of modern bears. It turned out that the Himalayan bears were the result of hybridization between the ancestors of modern northern (white, brown and baribal) and southern (Malayan and sloth) bears. These two lineages diverged about 5.91 million years ago and contributed approximately equally to the… Continue reading The Himalayan bear was the result of hybridization between northern and southern bears

Mandarin ducks bred for the first time in Moscow

Amateur ornithologists met a female mandarin duck with a chick in a Moscow park. This is the first reliable case of reproduction of this species in Moscow in the wild. Mandarin ducks are native to East Asia, but wild populations have long lived in Europe and some areas of the United States. Now, perhaps, these… Continue reading Mandarin ducks bred for the first time in Moscow

Koreans have made a hoverboard on an air cushion

Korean engineers have developed an air-cushioned hoverboard. It is capable of carrying a person, working as an unmanned cargo delivery driver, and simply driving without a load, for example, driving up to the person who called it. The hoverboard was originally a flying board from the sci-fi film Back to the Future 2. In the… Continue reading Koreans have made a hoverboard on an air cushion

South Korea successfully launches its own launch vehicle for the first time

The Nuri medium-class rocket made its first successful flight and launched a prototype and several satellites with a total mass of about 1.5 tons into orbit. This is the first missile developed entirely by South Korea. The launch was broadcast on YouTube. Nuri is a three-stage, mid-range rocket powered by liquid propellant engines running on… Continue reading South Korea successfully launches its own launch vehicle for the first time

Pine sawdust helped detect anomalous gravitational temperature gradient

Korean physicists have reported measuring the temperature gradient in the air column caused by gravity. To reduce the influence of the environment, the scientists protected the container with air with several layers of thermal insulation, and filled it with pine sawdust to combat convection. The result of their experience was several orders of magnitude greater… Continue reading Pine sawdust helped detect anomalous gravitational temperature gradient
