Analysis of ancient DNA revealed the history of Denisova cave
2021-06-29 19:44
In a new study, an international team of scientists analyzed DNA from more than 700 sediment samples collected from the Pleistocene layers of the Denisova Cave in Siberia, and found ancient mitochondrial DNA (mtDNA) of hominins and mammals in 685 samples and 175 samples, respectively.
The earliest evidence of hominin mtDNA is from Denisovans and is associated with stone tools that were deposited approximat...

Ancient Fungal Parasite of Ants Found Preserved in Baltic Amber
2021-06-27 12:16
In a paper published this month in the journal Fungal Biology, a duo of paleontologists from the United States and France described a new genus and species of ancient parasitic fungus found in a piece of 50-million-year-old amber from Europe’s Baltic region.
The newly-described species, named Allocordyceps baltica, is the oldest known fossil fungus of an ant.
“It’s a mushroom growing out of a carpenter an...
New meteorological services in the era of climate change
2021-06-26 13:50
The Executive Council of the World Meteorological Organization has adopted a decision on the international exchange of data on the Earth system. From now on, in addition to traditional meteorological, climatic and hydrological indicators, information on the state of the atmosphere, oceans, cryosphere and space weather will be collected. The WMO stressed that this is a new meteorological service in the era o...
A unique alloy for air and rail transport has been created
2021-06-25 13:03
Scientists of the National Research Technological University "MISiS" with the participation of colleagues from the Siberian Federal University and the " SPC of Magnetic Hydrodynamics "(Krasnoyarsk) have developed a technology for producing a unique heat-resistant aluminum alloy of increased strength, which can replace more expensive and heavy copper conductors in aircraft and in high-speed rail transport. T...
Coincidence? I think so: researchers use phylogenetics to untangle convergent adaptation in birds
2021-06-24 19:18
Researchers from Skoltech and their colleagues have shown that adaptation to similar environments hardly involves similar genomic positions when species are distantly related. The team investigated recurrent adaptations of wildlife birds’ mitochondria to high altitude, migration, diving, wintering, and flight. Repeatable substitutions are rather a coincidence than adaptation, which confirms the scientific o...
Syria floods: Humanitarians working ‘round the clock’ to provide urgent relief
2021-06-23 12:38
Humanitarian staff have been working “round the clock” to reopen access roads and provide emergency relief from the disastrous impact that recent floods have unleased on displaced people living in camps in northwest Syria, the UN’s deputy humanitarian coordinator there said on Friday.
Providing shelter, food, clean water and other relief supplies is “a massive undertaking…[that] will continue for months”,...
