Vietnamese advocates of solar power have begun a “Million Green Homes” project, aimed at spreading the use of solar power in the country instead of coal and other fossil fuels.
The project is being undertaken by the new Vietnam Coalition for Climate Action, formed in August by a group of leaders from business, academia and public organizations, and is designed to use a combination of public outreach and financial initiatives to get solar power on an additional million buildings.
Despite the “homes” in the project name, it is aimed at any small electricity consumers, especially those that can’t afford the cost of converting to solar power on their own, such as farms, small businesses, offices, and public buildings, such as hospitals and schools.
The project will focus on two types of solar power — panels connected to the national power grid that can supply electricity broadly and panels that generate electricity solely for the buildings to which they are attached.
Advocates are also encouraging Vietnamese to use more solar power for uses ranging from stoves to water heaters.
The project is being conducted by the Green Innovation and Development Centre, a Hanoi-based organization that promotes sustainable development in Vietnam and the Mekong region. The project is now examining how to spread awareness and make solar power affordable to under-served communities.
The center will start a pilot project next year for new solar power consumers all across Vietnam, including Hanoi in the north and several provinces, such as Thua Thien-Hue in central Vietnam, Dak Lak in the central highlands, and An Giang and Hau Giang in the south. The project will identify households and other small consumers eligible for support and help them install solar panels.
Environmentalists are pushing ahead with the effort, even though renewable energy discussions here have largely focused on government policies and corporate issues, and foreign investors want to be paid more for their electricity before they invest in solar power.
“Climate change poses a real threat to the natural environment that supports all of humanity and the critical habitats that we work to protect,” said Van Ngoc Thinh, Vietnam country director of the World Wide Fund For Nature, one of the members of the coalition.
“I call on all committed leaders from across the private sector, universities, subnational governments, and civil society to join the VCCA to take climate action,” he added.
Another environmental organization in the climate alliance, the Ho Chi Minh City-based Center of Hands-on Actions and Networking for Growth and Environment, or CHANGE, stressed in an email “the urgency of forming the alliance and the specific actions the alliance can contribute to promoting the use of rooftop solar [photovoltaic cells] and other energy-saving and green solutions.”
Much of that urgency comes from Vietnam’s increasing use of coal for energy, even while it considers itself one of the countries most at threat from climate change. The World Wide Fund For Nature in Vietnam said the Southeast Asian country plans to increase the number of coal-fired power plants from 20 now to 51 by 2030, which would cause carbon dioxide emissions to increase even more than expected.
Even amid government policies favoring more coal-fired plants, the government has expressed support for new types of energy sources.
“Vietnam’s government always encourages the development and effective use of renewable energy sources,” Deputy Prime Minister Trinh Dinh Dung said at an event this summer. (VOA)
The US researchers have discovered a class of immune cells that plays a role in miscarriage, which affects about a quarter of pregnancies.
Researchers at the University of California-San Francisco found that the recently discovered subset of cells known as extrathymic Aire-expressing cells in the immune system may prevent the mother's immune system from attacking the placenta and fetus.
The researchers showed that pregnant mice who did not have this subset of cells were twice as likely to miscarry, and in many of these pregnancies fetal growth was severely restricted.

"When you're pregnant, the immune system is seeing the placenta for the first time in decades -- not since the mother made a placenta when she herself was a fetus," said Eva Gillis-Buck, from UCSF.
"Our research suggests that this subset of immune cells is carrying out a sort of 'secondary education' -- sometimes many years after the better-known population of the educator cells have carried out the primary education in the thymus -- teaching T cells not to attack the fetus, the placenta and other tissues involved in pregnancy," she added. The findings are published in the journal Science Immunology.
The immune system has to be educated not to attack one's own tissues and organs to prevent autoimmune disease. But pregnancy presents a unique challenge since the fetus expresses proteins found in the placenta as well as proteins whose genetics are distinct from the mother.

"It was a conceptual leap to link Aire-expressing cells, which are critical for preventing autoimmune disease, to pregnancy," said Tippi Mackenzie, Professor of Surgery at UCSF's Center for Maternal Foetal Precision Medicine.
In the thymus, Aire-expressing cells begin interacting with other immune cells very early in life to teach them what not to attack. The thymus begins to shrink and is nearly gone by adulthood, by which time most immune cells have been educated. But as the thymus shrinks, the population of eTACs in lymph nodes and the spleen expands, the researchers explained.
The study suggests a healthy pregnancy may depend on having these cells around, they added. (IANS/KB)
The tiny emojis being shared on billions of devices worldwide can play a major role in digital communication, with most people saying that emoji compels them to feel more empathy towards others, according to an Adobe report.
Adobe's global emoji study found that emoji even helps people overcome language barriers and form connections that would otherwise be difficult to do.
"We were surprised and delighted by the discoveries made in the survey, most notably how enthusiastic respondents were for emoji as a means to express themselves," the company said in a statement.

Emojis sometimes get criticized for being overly saccharine, but this sweetness is key when it comes to diffusing some of the heaviness of online communication.
"Many of the emoji are focused on positive emotions, so it's easy to insert them into our conversations and lighten the mood," the Adobe study said.
It's not surprising that over half of those surveyed feel more comfortable using emojis than talking on the phone or in person.

This applies to less intense situations too. Dating, for example, can be tricky — especially when it's online or via digital apps, as it often is now.
The study also found that emoji even helps people overcome language barriers and form connections that would otherwise be difficult to do.
In celebration of World Emoji Day on Saturday, Adobe's '2021 Global Emoji Trend Report' surveyed 7,000 people in the US, the UK, Germany, France, Japan, Australia, and South Korea. (IANS/KB)
Following the grand Richard Branson show where he carried Andhra Pradesh-born Sirisha Bandla and fellow space travelers on his shoulders after successfully flying to the edge of space, it is time for Amazon Founder Jeff Bezos to applaud Sanjal Gavande, one of the key engineers who designed the New Shephard rocket set to take Bezos and the crew to space on July 20.
Billionaire Bezos is set to fly to the edge of space aboard what is touted as the world's first unpiloted suborbital flight. Born in Kalyan, Maharashtra, Gavande is a systems engineer at Blue Origin who always dreamt of designing aerospace rockets.

Bezos, his brother Mark, aviation pioneer Mary Wallace 'Wally' Funk, and other passengers are set to liftoff from west Texas and travel just beyond the edge of space on July 20. Blue Origin announced this week that Oliver Daemen, an 18-year-old high school graduate from the Netherlands, would join the crew.
Oliver is the son of millionaire Joe Daemen, Founder, and CEO of the Dutch investment company Somerset Capital Partners. Blue Origin, however, did not reveal how much Daemen paid for his son's trip to space. Bezos chose July 20 as the launch date to honor the 52nd anniversary of the Apollo 11 moon landing.

The launch site for Blue Origin's first human flight will be in a remote location north of Van Horn, Texas, from where the firm had launched New Shepard for previous flights. Blue Origin has received final approval from the Federal Aviation Administration (FAA) to carry humans on the New Shepard rocket into space.
On July 12, Bandla touched the edge of space with three others, including Virgin Galactic's billionaire CEO Richard Branson. Bandla vaulted into space onboard VSS Unity 22. After the successful spaceflight, Branson carried the Indian-American on his shoulders while celebrating their flight to space, at Spaceport America in New Mexico. (IANS/KB)
