By analysing a large dataset from the UK Biobank, which included genetic and trait information from nearly 300,000 Brits of non-African ancestry, the researchers identified specific Neanderthal genes responsible for certain traits in modern humans. These traits include significant influences on the immune system. However, the study also reveals that overall, modern human genes are gradually overpowering Neanderthal genes over successive generations.

Researchers, including those from Cornell University, have developed advanced computational genetic tools to investigate the impact of interbreeding between non-African humans and Neanderthals that occurred approximately 50,000 years ago.&nbsp;

The study specifically focuses on individuals of European ancestry who descended from those who migrated from Africa before Neanderthals became extinct.&nbsp;

<h2>Genetic variants, influences</h2>

Using precise statistical methods, the research team examined over 235,000 genetic variants likely to have originated from Neanderthals.&nbsp;They identified 4,303 differences in DNA that play a substantial role in modern humans, impacting 47 distinct genetic traits.&nbsp;

These traits encompass various characteristics such as metabolic rates and natural immune resistance to certain diseases.&nbsp;Unlike previous studies, this research effectively excluded modern human genes from the analysis, focusing specifically on variants attributed to Neanderthal genes.

Senior investigator Sriram Sankararaman, an associate professor at the University of California, Los Angeles said, "For scientists studying human evolution interested in understanding how interbreeding with archaic humans tens of thousands of years ago still shapes the biology of many present-day humans, this study can fill in some of those blanks."

"More broadly, our findings can also provide new insights for evolutionary biologists looking at how the echoes of these types of events may have both beneficial and detrimental consequences."

<h2>Future research</h2>

Although the study primarily examined individuals of European ancestry living in the United Kingdom, the computational tools developed by the research team can potentially be applied to other large databases.&nbsp;

This opens up avenues for exploring the genetic influences of archaic humans on modern humans and gaining insights into human evolution. The findings have implications for evolutionary biologists, shedding light on the beneficial and detrimental consequences of interbreeding events between ancient and modern humans.

New genetic tools uncover Neanderthal influence on modern human traits

What makes us human? Primate genome study offers some clues

Wuhan city in China, where the coronavirus first appeared in 2019 and is now witnessing a recurrence of illnesses, has tested 11.23 million of its over 12 million residents, according to local officials.

Six additional locally transmitted confirmed cases and 15 asymptomatic patients were reported in Wuhan.&nbsp;

According to data from Hubei province, Wuhan's capital, 47 cases of COVID-19 have been confirmed, including 31 locally transmitted.

Xinhua news agency reported there were 64 cases of asymptomatic people under medical supervision in Wuhan along with 11.23 million samples collected for nucleic acid tests.

On August 4, the city started a new, all-encompassing testing drive. The findings of 10.8 million samples have been made public.

Li Yang, the deputy head of the Hubei provincial centre for disease control and prevention, told the media on Saturday that health workers are still checking and confirming.&nbsp;

A Xinhua report said the city has placed 157 residential communities under closed-loop management. COVID-19 resurfaced in the city after the city dealt with its first surge of coronavirus cases in December.

On Saturday, China's National Health Commission announced that 139 new cases of COVID-19 had been recorded on Friday.

93,605 cases of COVID-19 had been confirmed on the mainland as of Friday, the commission said.&nbsp;

Among these, 1,444 were still receiving treatment, 39 were in severe conditions, and 4,636 had died.

Coronavirus resurgence in Wuhan leads to testing of 11.23 million

In the search of <a href="https://www.wionews.com/topics/coronavirus">COVID-19 origin</a>, the US intelligence agencies have accessed massive genetic data from China's controversial Wuhan lab and are scouring them to find the origin of the pandemic, a US media report said on Thursday.

It's unclear exactly how or when US intelligence agencies gained access to the information, but the machines involved in creating and processing this kind of genetic data from viruses are typically connected to external cloud-based servers — leaving open the possibility they were hacked, CNN quoted sources as saying.

The massive data contains genetic blueprint information from Wuhan lab's virus samples.

Multiple officials in the US still believe that China may have been the source of the COVID-19 outbreak, the media report said.

Earlier, multiple experts and media reports have also warned that coronavirus could have been leaked from China's Wuhan lab.

However, the Communist regime has been in strong denial for a long time. But when a team of the World Health Organisation proposed to visit the Wuhan lab and the city's controversial Huanan Seafood market, Beijing unnecessarily delayed the visit giving bogus reasons. The communist regime's such steps strengthen the Wuhan leak theory.
