Самые крупные сухопутные животные прошлого предпочитали тропики

2021-12-21 15:16 Палеонтологи из США и Испании пришли к выводу, что динозавры-зауроподы проживали в более теплых регионах планеты. К зауроподам относят самых крупных животных, когда-либо обитавших на суше. Среди них: диплодоки, брахиозавры, бронтозавры и апатозавры. Эти существа отличались длинной шеей, маленькой головой, мощным хвостом и толстыми ногами, похожими на колонны. Зауроподы появились около 210 миллионов лет наза...

38℃ record Arctic temperature confirmed, others likely to follow: WMO

2021-12-20 19:14 A new and disturbing high temperature record for the Arctic of 38 degrees Celsius, or just over 100 degrees Fahrenheit, was confirmed by the World Meteorological Organization (WMO) on Tuesday. Worryingly, the temperature reading taken last June in the Siberian town of Verkhoyansk – which is located 115 kilometres north of the Arctic Circle - is “just one of a series” of potentially record-breaking observat...

Челюсти динозавров-теропод становились сильнее по мере эволюции

2021-12-18 19:56 Большинство теропод были хищниками, реже — всеядными и растительноядными (к тероподам, кстати, сегодня относят и современных птиц). Они передвигались на двух ногах, что позволяло им бегать быстрее остальных динозавров. Еще у них был более широкий угол обзора, а свободные от ходьбы передние лапы могли выполнять другие функции: например, придерживать добычу во время поедания. Такая биомеханика, впрочем, несл...

A person's biological clock works differently due to stress

2021-12-12 10:30 The work of the human body is regulated by various rhythms - "clocks", among which there are, for example, circadian rhythms - an internal rhythm with a period of about 24 hours, familiar to us as the "sleep-wakefulness" cycle. For such clocks to be useful, they must be synchronized with the outside world: for example, the circadian rhythm depends on light information. However, in addition to the 24-hour ci...

Subantarctic Armored Dinosaur Had Bizarre Tail Weapon

2021-12-11 09:55 The new dinosaur species lived in what is now Chile during the Upper Cretaceous epoch, some 74 million years ago. Named Stegouros elengassen, it was between 1.8 and 2 m (5.9-6.6 feet) long including its short tail.

LIFE OF THE HIGGS BOSON

2021-12-08 11:23 The Higgs boson is peculiar in many respects. Like most other elementary particles, it is unstable and lives only for an extremely short time, 1.6 x 10-22 seconds, according to the established theory of particle physics (the standard model). Pretty short, isn't it? Compare this number to 880 seconds (about 15 minutes), the average lifetime of a neutron outside an atomic nucleus. The lifetime of an unsta...

We haven't seen such a robot with realistic facial expressions yet

2021-12-07 13:58 The robot from the British company Engineered Arts impresses with its realism of movement and facial expressions. The Ameca robot may be disgusting to many, but undoubtedly it is a huge step forward in the development of robotics.
