Swedish teen climate activist Greta Thunberg will leave North America and begin her return trip across the Atlantic on Wednesday aboard a 48-foot (15-meter) catamaran sailboat whose passengers include an 11-month-old baby.
The boat leaves little to no carbon footprint, boasting solar panels and a hydro-generators for power. It also has a toilet, unlike the boat on which she sailed from the United Kingdom to New York in August. That one only had a bucket.
“There are countless people around the world who don’t have access to a toilet,” she said about the upgrade. “It’s not that important. But it’s nice to have.”
Thunberg spoke Tuesday inside the tight confines of the catamaran, named La Vagabonde, as it was docked in Hampton, Virginia, near the Chesapeake Bay’s mouth. She’s hitching a ride to Spain in hopes of attending a United Nations climate meeting in Madrid in early December.
The owners of the boat are Riley Whitelum and Elayna Carausu, an Australian couple who have an 11-month-old son named Lenny. The family, which has a large online following, responded to Thunberg’s call on social media for a carbon-free ride to Europe. An expert sailor, Nikki Henderson, is also coming along.
The trip could take two to four weeks, and November is considered offseason for sailing across the Atlantic. As Thunberg spoke Tuesday, the temperature had dipped into the 30s as sleet turned into light snow.
But the 16-year-old, who refuses to fly because of the carbon price of plane travel, didn’t seem bothered.
“I’m looking forward to it, just to be able to get away and recap everything and to just be disconnected,” she said.
Thunberg just finished a nearly three-month trip through North America, where she gave an impassioned speech before the United Nations and took part in climate strike rallies and protests from California to Colorado to North Carolina.
She’s become a symbol of a growing movement of young climate activists after leading weekly school strikes in Sweden that inspired similar actions in about 100 cities worldwide.
She’s also drawn criticism from conservative commentators in the U.S. as well as Russian President Vladimir Putin. But she brushed off the criticism during her round of back-to-back interviews in the catamaran on Tuesday, saying that yes, she is too young to be doing this.
“It should be the adults who take that responsibility,” Thunberg said. “But it feels like the adults and the people in power today are not.”
When she looks back on her time in the U.S. and Canada, Thunberg said the things that stick out the most include a glacier in Canada’s Jasper National Park that is destined to disappear “no matter what we do.”
A visit to the Standing Rock Indian Reservation, where there have been protests over a pipeline, also left an impact.
“I was actually quite surprised to see how bad the indigenous people have been treated,” she said. “They are the ones who are being impacted often the most and first by the climate and ecological crisis. And they are also the ones who are at the front line trying to fight it.”
She also was surprised at how much she was recognized.

“There are always people who come up to me and ask for selfies and so on,” she said. “So, that really gives you an idea of how big the climate movement has reached.” (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)
