As reported by Arkeonews, perhaps the reason for the unusual ritual was the appearance of the deceased.… Continue reading The burial of a “vampire woman” with a sickle on her neck and a castle on her leg was found in Poland.

Physicists were able to obtain acoustic frequency combs at 10 gigahertz

American physicists have manufactured a hybrid system from a nonlinear oscillatory circuit and an acoustic resonator connected by a piezoelectric contact. This combination made it possible to impart nonlinearity to acoustic modes at a frequency of 10 gigahertz. The authors were able to generate coherent acoustic frequency combs in their setup, which will help combat… Continue reading Physicists were able to obtain acoustic frequency combs at 10 gigahertz

The first launch of the SLS rocket was postponed due to a hydrogen leak

The first flight of the SLS super-heavy launch vehicle carrying the Orion spacecraft was postponed due to problems with a hydrogen leak in one of the rocket's core stage engines. The new launch date is set for September 2, 2022. The first launch attempt was broadcast on YouTube. Artemis 1 is the first flight of… Continue reading The first launch of the SLS rocket was postponed due to a hydrogen leak

Watering with ethyl alcohol protected the rhizome from drought

Japanese geneticists have proposed increasing the drought resistance of plants using ethanol. They watered Tal's rhizomes (Arabidopsis thaliana) with a weak alcohol solution for three days and showed that this helped the plants survive the subsequent three-week drought. In response to alcohol, the plant activates the synthesis of the stress phytohormone, abscisic acid, which helps… Continue reading Watering with ethyl alcohol protected the rhizome from drought

A rare case with six weights was discovered in Gnezdovo

Archaeologists excavated two mounds of the Forest group in Gnezdovo. In one of them there were no artifacts or human remains – only organic decay. The other contained several valuable items, including a battle ax and a knife. The most unusual find was a rare wooden case with a bone lid, inside which were six… Continue reading A rare case with six weights was discovered in Gnezdovo

Experimental antibiotic wipes out resistant gram-negative bacteria

American researchers have developed a new antibiotic that is effective against drug-resistant gram-negative bacteria. In experiments on isolates of nosocomial bacteria and on mouse models of infections caused by them, it demonstrated high activity, while having virtually no effect on components of the normal human microbiota. The report on the work was published in the… Continue reading Experimental antibiotic wipes out resistant gram-negative bacteria

Kākāpō numbers have risen to their highest level in almost 50 years. Now there are 252 of them

Kākāpō numbers have reached their highest levels in nearly fifty years. According to a press release from New Zealand's Ministry of Environment, the rare parrots have given birth to 55 chicks this year, bringing the total number of representatives of this species to 252 individuals. By comparison, in 1995 there were only 51 kakapo left… Continue reading Kākāpō numbers have risen to their highest level in almost 50 years. Now there are 252 of them
