Traces of cockroach ootheca found in Jomon period ceramics

Archaeologists have examined 4,000- to 5,300-year-old Jomon period pottery discovered in Japan. In five artifacts they found traces of cockroach ootheca. One of them was laid by Japanese cockroaches (Periplaneta japonica), the rest look like smoky cockroaches (P. fulinginosa). Previously, it was believed that the latter species was brought to Japan only in the 18th–19th… Continue reading Traces of cockroach ootheca found in Jomon period ceramics

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.

Evolution forced mammals to recreate salivary proteins fifteen times

American bioinformaticians have discovered traces in the genomes of mammals of 15 independent occurrences of new proteins responsible for the viscosity of saliva. According to the findings of the authors of a study published in Science Advancesthe culprit is a region of the genome with a high mutation rate and selection pressure during the evolutionary… Continue reading Evolution forced mammals to recreate salivary proteins fifteen times

Found inner charm in proton

The NNPDF collaboration of European theorists reported the results of a search for the internal charm of the proton using a large array of experimental data. According to their results, charm quarks can consistently transfer up to one percent of the proton's momentum with a confidence of three standard deviations. The study was published in… Continue reading Found inner charm in proton

Malaysian researchers modeled the appearance of a “Penang woman”

Malaysian researchers have shown what a woman whose remains were discovered at the Neolithic site of Guar Kepa in Penang state might have looked like. The age of the so-called “Penang woman” is estimated at more than 5,000 years. To reconstruct the face, specialists used the method of forensic approximation and virtual 3D reconstruction. The… Continue reading Malaysian researchers modeled the appearance of a “Penang woman”
