A scientifically accurate and valid epidemiologic study of reproductive problems among the families of veterans exposed to radiation from atomic bombings and nuclear weapons tests is not feasible, concluded an Institute of Medicine (IOM) committee in a new report.

High-quality early care and education (ECE) is critical to positive child development and has the potential to generate economic returns, but the current financing structure of ECE leaves many children without access to high-quality services and does little to strengthen the ECE workforce, says a new report from the National Academies of Sciences, Engineering, and Medicine.

We urge the U.S. Department of Homeland Security to immediately stop separating migrant children from their families, based on the body of scientific evidence that underscores the potential for lifelong, harmful consequences for these children and based on human rights considerations.

The U.S. Department of Defense’s Military Family Readiness System (MFRS) — a network of agencies, programs, services, and individuals that promotes the well-being and quality of life of military service members and their families — lacks a comprehensive, coordinated framework to support well-being, resilience, and readiness, says a new report from the National Academies of Sciences, Engineering, and Medicine.

Eight-year-old Mariana Aceves is doing her math homework — subtraction by counting backwards — while sitting on the bed she shares with her mom, Lorena Aceves.

They're sitting on the bed because they have nowhere else to go: they live in an 8-foot-by-12-foot room called a tiny house. It's part of Seattle's transitional housing where people experiencing homelessness can live until they find a job and a place of their own.

There's room for the bed they share, a TV shelf, "and a little tiny plastic dresser, and then all of our clothing and our food goes underneath our bed," Lorena Aceves says.

Tens of millions of kids are taking classes online at home right now because of the coronavirus pandemic. That's hard enough for most families. But, if you're homeless and have no computer, sketchy wifi, and no quiet place to study, it's even more difficult. That's the case for the one and a half million school kids currently experiencing homelessness across the U.S.

When Seattle's schools closed in March, Aceves had to quit her new job, because she couldn't find childcare. She and her daughter have been holed up in their tiny house ever since.

"It's the boredom," Aceves says, "and me trying to reach out and find resources — work, a car, things like that — while also making sure that she's entertained."

Aceves and her daughter have a tiny amount of private space. Other homeless families have no privacy at all.

Sixteen-year-old Capelle Belij is living with his parents at a shelter, part of a network of family shelters in the Seattle area run by the nonprofit Mary's Place.

The Belijes share a room with two other families, divided only by curtains.

"My friends, like, come up to my bed space and ask if I want to play or something," Belij says. "If we had our own place, I could learn better."

Three-quarters of children and youth considered homeless live doubled-up with another family. That's the situation for the family of 17-year-old Michelle Aguilar. She's part of KUOW's youth reporting program, called RadioActive.

"I can't really find a specific space where it's like quiet and calm and I can actually have wifi," Aguilar says.

Since Aguilar's shared bedroom doesn't have wifi, she ends up in the living room or kitchen with the rest of her family.

"And they just, like, continue their chaotic life of yelling and screaming and, like, playing music and listening to the TV and cooking," she says.

"Whenever I'm, like, in the environment of it being really loud," Aguilar says, "I tend to, like, read over and over and over and over the assignment."

"We're definitely very concerned with there being an achievement gap during this time," says Tisha Tallman, the executive director of the National Center for the Education of Homeless Children and Youth. "The longer this goes, the more likely our children are to fall behind."

And, Tallman adds, schools provide much more than an education: many homeless kids get two meals per day there, and they rely on it as a safe and stable place to be.

Back in her tiny house, Lorena Aceves is trying to keep her daughter's education on track with a strict schedule of math, reading, and typing.

"Even though this is frustrating," Aceves says, "we are having this time together and that's something typically that we don't have."

Aceves says it's good to feel close to her daughter during a time that she has to stay far away from nearly everyone else.

Pollination studies have, to date, focused almost entirely on bees , butterflies and hoverflies; however, other kinds of flies also have an important role to play in this vital ecosystem service, a new study suggests. Using data from 33 farms, the researchers found that non-hover flies were in fact responsible for carrying 84% of the pollen transferred by flies between flowers in farmland.

New research has compared the environmental impact of four alternative methods of water supply in Copenhagen. Results indicated that rain and stormwater harvesting is the most environmentally sound approach, whilst desalination currently has a large environmental impact, mainly due to electricity use. However, if freshwater extraction is included as an impact, the environmental credibility of desalination is improved.

For people in the UK to eat the recommended 280 grams of fish per week, the country would have to rely on aquaculture and increasingly on imports of both wild and farmed fish from poorer countries, a recent study has revealed. This can have social and environmental implications and the researchers urge governments, particularly in developed countries, to consider nutritional advice in a global context, to minimise the impact of fish exports from poorer countries.

Shortages of indium, a key metal found in thin-film solar cells, could limit their large-scale deployment in the future. A new study has outlined four ways that indium supplies could be increased to meet future demand. For example, indium could be extracted more efficiently from zinc ores, or historic wastes containing indium could be processed to extract the element.

Indium, a unique metal, is in short supply worldwide and is not recycled at the end of its life (EoL). Indium is used in a wide range of technologies, causing regions across the world that are reliant on its import — such as Europe — to be concerned about security of supply. Primary sources of indium are thought to be sufficient for medium-term needs, but with growing demand comes growing concern over long-term supply. A new study has conducted a material flow analysis and examined secondary sources of indium within European ‘urban mines’ and in-use stocks (IUS) of indium products, identifying these as potential sources of 500 tonnes of indium — if it were recycled at EoL.

Spanish Basque Country, grasslands were found to supply the greatest amount of river water, followed by native woodlands, with exotic woodland plantations providing the least. Researchers also call for more comprehensive analyses of ecosystem services, including carbon sequestration and biodiversity, to inform land-use policy.

Unusually warm or cool Pacific sea surface temperatures, known as El Niño and La Niña, can be used to reliably predict anomalies in flood risk for river basins that cover 44% of the Earth’s land surface, a new study has shown. The researchers also quantified overall flood damage by combining information on flood risk with estimates of damage to economies and numbers of people at risk. This could help improve flood disaster planning, they say.

With authorities completely sealing the areas, FMCG companies said they are facing problem moving trucks through such localities to other places.

As the climate changes, animal species are predicted to adapt by moving northwards so they can remain within their preferred temperature range. Now, researchers have found that bird and butterfly populations are not keeping up with changing temperatures and, on average, European bird and butterfly species lag around 212km and 135km, respectively, behind climate changes.

Pollination studies have, to date, focused almost entirely on bees, butterflies and hoverflies; however, other kinds of flies also have an important role to play in this vital ecosystem service, a new study suggests. Using data from 33 farms, the researchers found that non-hover flies were in fact responsible for carrying 84% of the pollen transferred by flies between flowers in farmland.

To estimate the losses of wild pollinators across Great Britain, a study mapped records of 353 wild bee and hoverfly species, collected across the country from 1980 to 2013. It found that a third of species decreased, while a tenth increased. On average, the geographic range of bee and hoverfly species declined by a quarter, which equates to a net loss of 11 species from each 1km grid square (with uncommon species more harshly affected), highlighting a significant risk to biodiversity, pollinators, and their ecosystems.

But there is a lot of upward momentum in supply that needs to be reversed.
