The unrest in Venezuela is turning into a battleground of rhetoric between the United States and Russia.
After a telephone conversation between Secretary of State Mike Pompeo and Foreign Minister Sergey Lavrov on Wednesday, the Russian warned of “the most drastic of consequences” if the U.S. continued what he called “aggressive steps.”
The State Department was more muted, saying only that Russian and Cuban intervention was “destabilizing for Venezuela.”
But White House national security adviser John Bolton said, “This is our hemisphere. It’s not where the Russians ought to be interfering. This is a mistake on their part. It’s not going to lead to an improvement of relations.”
Pompeo said again Wednesday that the U.S. was prepared to use military action in Venezuela: “If that is what is required, this is what the United States will do.”
But Pompeo and President Donald Trump have not specified what would prompt the U.S. to intervene militarily.
Cuba denies troops in Venezuela
Meanwhile, a top Cuban diplomat denied U.S. accusations that thousands of Cuban troops were on the ground in Venezuela.
“Cuba does not participate in military operations nor in security operations in Venezuela,” Cuban Chief of U.S. Affairs Carlos Fernandez de Cossio told the Associated Press.
He said the 20,000 Cubans in Venezuela were primarily medical workers.
But he did say, as hemispheric partners, Cuba and Venezuela have the sovereign right to military and intelligence cooperation.
Cuba and Russia are longtime allies of Venezuela and its socialist government. Russia has supplied economic support and military equipment to the Maduro government, while Venezuela has sent billions of dollars in oil to Cuba in exchange for medical aid.
Guaido: More demonstrations
Supporters of opposition leader Juan Guaido, who is recognized by the U.S. and more than 50 other nations as Venezuela’s rightful president, filled the streets again Wednesday, hurling rocks at police who responded with tear gas.
Guaido said a staggered industrial action would start Thursday, leading to a general strike.
“We’re going to remain in the streets until we achieve freedom for the Venezuelan people. The regime will try to increase the repression. It will try to persecute me,” he told demonstrators Wednesday.
As head of the opposition-controlled National Assembly, Guaido used the constitution to declare Nicolas Maduro’s presidency illegitimate, saying his election in December was a fraud.
Millions of Venezuelans — sick of out-of-control inflation, severe food and fuel shortages, a lack of medical care, and periodic blackouts — have fled the country.
Maduro accuses Guaido of coup
Maduro is accusing Guaido of trying to carry out a U.S.- and Colombian-supported coup and says the opposition will fail.
He said demonstrators would be prosecuted “for the serious crimes that have been committed against the constitution, the rule of law and the right to peace.”
Neither Maduro nor Guaido can succeed, however, without the support of Venezuela’s powerful military. While many of the rank-and-file soldiers have joined the opposition, Maduro still has the backing of generals and other top military chiefs. (VOA)
Canadian researchers have discovered an overlooked gene that plays a major role in the development of antibodies, which help the immune system recognize and fight viruses including SARS-CoV-2, bacteria and other causes of infectious disease. The gene -- FAM72A -- facilitates production of high-quality antibodies by enabling the effect of an enzyme called AID (for Activation-Induced Deaminase), the researchers showed.
Immunologists have known for two decades that AID is essential to produce antibodies capable of clearing infections, but the full mechanism of its effect has remained unknown. "Our findings answer the long-standing question of how AID does its work," said Alberto Martin, a professor of immunology at the University of Toronto's Temerty Faculty of Medicine. "FAM72A helps AID to promote mutations in antibody genes that are essential for the development of effective antibodies," he added.

Genetic mutations that lead to lasting changes in DNA occur through a process called mutagenesis. In the context of antibody development, mutagenesis unfolds largely through the AID-driven mechanisms called somatic hypermutation and class switch recombination -- both of which help antibodies gain the diversity and potency they need to counter a wide range of pathogens.
The results published in the journal Nature will help researchers better understand antibody development broadly, but they also have implications for cancer. Uncontrolled mutagenesis in B cells that produce antibodies is linked to B cell lymphoma, and FAM72A is present at very high levels in other cancers such as gastrointestinal, breast, lung, liver and ovarian cancers.
"Our data show that high levels of FAM72A promote mutations in antibody genes, so increased levels of FAM72A could spur cancer development, progression or drug resistance by increasing mutagenesis,a Martin said. Martin's team is now exploring those possibilities. Intriguingly, unlike other mammals, humans have four gene versions of FAM72A and their roles in cancer and antibody production are still unknown.

Mahanadi Coalfields Limited (MCL), a subsidiary of Coal India will set up a 50 megawatt (MW) solar power plant in Odisha's Sambalpur at a total cost of Rs 301.92 crore, moving steadily towards its goal to achieve carbon neutrality by 2024. MCL has placed a turnkey order to set-up a 50 MW solar power plant with a Chennai-based firm M/s Hild Energy Ltd, which will establish this green energy project within a timeline of 10 months, the MCL said in a statement on Saturday.
This solar plant would cater to the captive power requirement of MCL. The Central PSU had successfully set-up a 2MW solar power plant in Sambalpur in 2014. The company said it has pledged a target of installing 182 MW of solar power by 2024 in order to become a net zero energy company, aligning itself to use cleaner forms of energy for coal production.

This 50 MW solar power project will reduce CO2 emission by 91,020 tonnes per annum and carbon offsets of around 24,824 tonnes per annum, claimed the MCL. MCL is the leading production subsidiary of Coal India, having mining operations in Angul, Jharsuguda and Sundargarh districts of Odisha. Having achieved the highest ever capital expenditure of Rs 2,419 crore in the financial year 2020-21, the company has coal production and dispatch targets of 163 million tonnes and 182 million tonnes, respectively.
MCL was the coal mining company to introduce environment-friendly surface miner technology, which contributes over 95 per cent in coal production. As another environment-friendly initiative, the company has successfully introduced vertical rippers for blast-less over-burden removal in Hingula and Kaniha opencast projects. (IANS/ MBI)

As the nation celebrated the 114th birth anniversary of his father - renowned poet Harivansh Rai Bachchan - megastar Amitabh Bachchan remembered his dad as he penned a heartfelt note for him. The actor took to his blog where he poured his heart out and also shared an unseen photo with his father. The image in question is from Big B's wedding in 1973, where the two are caught in a sweet moment as they look at each other.
Amitabh Bachchan wrote on his blog,
"My Father , my all .. November 27th his birth in the year 1907 .. Which makes it his 114th Anniversary .. He is in the heavens, with my Mother and they celebrate .. as do we , in thought word and deed .. (sic). But first."
He then posted the picture followed by elaborate paragraphs. The megastar wrote,
"Those rare moments when one would find himself rushing against the winds to prevent the distance between us and to close it down as soon as it can be. The day of my wedding and his expression of fulfilment to not just be in congratulation but instead to be in the face of a belief, a chime, an ultimate season of love and great passion, of the quarries of the fears and conditionings of these deprived gym routines kart ..(sic)". "This could have been unknown for long facilitating years, to give not expected versions and lastly large scale informations of the insides ; but as time passed by, as does now , they explained purposely, the values of education and similarity .. Be in peace and love .. (sic)",
the veteran actor concluded his note. (IANS/ MBI)
