Ornithologists have described a new bird species from the subantarctic islands

Ornithologists have described a new species of bird that lives on the Diego Ramirez Islands south of South America. It is called the subantarctic rayadito. In the past, the local population was thought to be the spiny-tailed rayadito, which is widespread in Chile and Argentina. However, the analysis showed that individuals from the Diego Ramirez… Continue reading Ornithologists have described a new bird species from the subantarctic islands

Ice-resistant self-propelled platform “North Pole” went on its first voyage

The research vessel North Pole has set out on its maiden voyage, the Arctic and Antarctic Research Institute said in a statement. It will carry an expedition to the Central Arctic, which will continue the research of the region begun in the 1930s. The 41st Arctic drifting polar station will continue regular research of the… Continue reading Ice-resistant self-propelled platform “North Pole” went on its first voyage

Meteorologists predicted the first “triple” La Niña this century

The cold phase of the Southern Oscillation – La Niña – may last until the end of 2022 – early 2023, according to a press release from the World Meteorological Organization. If meteorologists' forecasts come true, for the first time this century, La Niña will be observed for three consecutive winters in the Northern Hemisphere.… Continue reading Meteorologists predicted the first “triple” La Niña this century

The January eruption of the Tonga volcano triggered a 90 meter high tsunami.

The initial height of the tsunami caused by the eruption of the Hunga Tonga Hunga Ha'apai volcano on January 15, 2022 was 90 meters. These conclusions were reached by researchers from the UK, New Zealand, Croatia and Japan, who analyzed changes in atmospheric pressure and sea level and created nine models of a volcanic tsunami.… Continue reading The January eruption of the Tonga volcano triggered a 90 meter high tsunami.

Starlink satellites will be able to connect directly to regular smartphones

The new generation of Starlink satellites will allow anyone with a smartphone to connect to the mobile network and the Internet, even from places where there is no terrestrial coverage. The connection speed will be from two to four megabits per second. This was announced by SpaceX CEO Elon Musk and T-Mobile President Mike Sievert.… Continue reading Starlink satellites will be able to connect directly to regular smartphones

Astronomers have found the best candidate for an ocean exoplanet

Astronomers using ground-based and space telescopes have confirmed the discovery of the super-Earth TOI-1452b around a red dwarf. According to scientists, it is best described by a model of an exoplanet with a global water ocean, the mass of which makes up 22 percent of the total mass of the planet. It is expected that… Continue reading Astronomers have found the best candidate for an ocean exoplanet

Simulated plankton surfed on turbulence and accelerated twice

Physicists and biologists from France and the USA have modeled the movement of plankton, which uses vortices in the water to move faster, riding them like surfers on waves. To do this, scientists derived the equation of motion of plankton, which measures the local flow gradient and changes its direction so as to swim upward… Continue reading Simulated plankton surfed on turbulence and accelerated twice

Warming oceans are causing the North Atlantic hurricane season to start earlier

American climatologists have recorded a gradual shift in the beginning of the hurricane season in the North Atlantic. Since 1900, on average, every ten years the hurricane season begins five days earlier, and hurricanes reach the coast two days earlier. According to researchers, this is due to warming of the ocean surface. Article published in… Continue reading Warming oceans are causing the North Atlantic hurricane season to start earlier

Direct migration trajectories of dead heads indicated the presence of an internal compass

Entomologists have tracked the autumn migrations of death's-head hawk moths across the Alps. It turned out that these moths move in a straight path, adjusting the direction and altitude of their flight depending on where the wind is blowing. As noted in the magazine article ScienceThe findings indicate that death's heads have an internal compass.… Continue reading Direct migration trajectories of dead heads indicated the presence of an internal compass

Global climate change has played into the hands of most infectious diseases

An empirical systematic study conducted by American scientists showed that global climate change associated with the emission of greenhouse gases increases the prevalence of 58 percent of infectious diseases to one degree or another, and decreases it in only 16 percent. The report on the work was published in the journal Nature Climate Change. Continuously… Continue reading Global climate change has played into the hands of most infectious diseases
