NASA is planning to launch a new mission to study how the Sun generates and releases giant space weather storms — known as solar particle storms — into planetary space.

The new mission, called the Sun Radio Interferometer Space Experiment (SunRISE), is an array of six CubeSats operating as one very large radio telescope, the US space agency said on Monday. NASA has awarded $62.6 million to design, build and launch SunRISE by no earlier than July 1, 2023.

Understanding how the Sun generates and releases giant space weather storms can ultimately help protect astronauts travelling to the Moon and Mars by providing better information on how the Sun’s radiation affects the space environment they must travel through.

“We are so pleased to add a new mission to our fleet of spacecraft that help us better understand the Sun, as well as how our star influences the space environment between planets,” said Nicky Fox, Director of NASA’s Heliophysics Division.

“The more we know about how the Sun erupts with space weather events, the more we can mitigate their effects on spacecraft and astronauts.” The mission design relies on six solar-powered CubeSats — each about the size of a toaster oven — to simultaneously observe radio images of low-frequency emission from solar activity and share them via NASA’s Deep Space Network.

The constellation of CubeSats would fly within six miles (9.6 kms) of each other, above Earth’s atmosphere, which otherwise blocks the radio signals SunRISE will observe.

Together, the six CubeSats will create 3D maps to pinpoint where giant particle bursts originate on the Sun and how they evolve as they expand outward into space. This, in turn, will help determine what initiates and accelerates these giant jets of radiation.

NASA is seeking US citizens for an eight-month study on social isolation in preparation for missions to Mars and the moon.

The international space agency is preparing for its next spaceflight simulation study and is seeking healthy participants to live together with a small crew in isolation for eight months in Moscow, Russia.

Participants will be staying in a lab located in Moscow, and they will experience environmental aspects similar to those astronauts are expected to experience on future missions to Mars that will have crew members from different nations.

NASA is looking for highly motivated and healthy individuals between the ages of 30 and 55 who are fluent in both English and Russian. They must also have an MS., PhD, MD. or have completed military officer training.

The space agency will consider other participants with a bachelor’s degree and other qualifications such as military or professional experience.

They will study the psychological and physiological effects astronauts are likely to face as a result of isolation on long missions.

According to NASA, participants will experience environmental aspects similar to those astronauts are expected to experience on future missions to Mars.

A small international crew will live together in isolation for eight months conducting scientific research, using virtual reality and performing robotic operations among a number of other tasks during the lunar mission.

The research is being done to study the effects of isolation and confinement as participants work to complete simulated space missions.

Results from ground-based missions like this help NASA prepare for the real-life challenges of space exploration and provide important scientific data to solve some of these problems and to develop countermeasures.

Participants will be compensated, and there are varying levels of pay depending on whether you’re associated with NASA.

This study builds on a four-month study conducted in 2019. The SIRIUS-19 analog mission had six participants — two US citizens and four Russians — isolated in a metal habitat that acted as their spacecraft, lunar lander and home. (IANS)

COVID-19 Poses Serious Complications, Even Death Risk for Children: Research

Children at a higher risk from COVID-19

Researchers, including one of Indian-origin, have revealed that children, teenagers and young adults are at greater risk for severe complications from COVID-19 and those with underlying health conditions are at even greater risk of death.

“This study provides a baseline understanding of the early disease burden of COVID-19 in pediatric patients,” said study researcher Hariprem Rajasekhar from Robert Wood Johnson Medical School Department of Pediatrics in the US. “The findings confirm that this emerging disease was already widespread in March and that it is not universally benign among children,” Rajasekhar added.

Published in the journal JAMA Pediatrics, the study followed 48 children and young adults – from newborns to 21 years old — who were admitted to pediatric intensive care units (PICUs) in the US and Canada for COVID-19 in March and April.

More than 80 per cent had chronic underlying conditions, such as immune suppression, obesity, diabetes, seizures or chronic lung disease. Of those, 40 per cent depended on technological support due to developmental delays or genetic anomalies. More than 20 per cent experienced failure of two or more organ systems due to COVID-19, and nearly 40 per cent required a breathing tube and ventilator.

At the end of the follow-up period, nearly 33 percent of the children were still hospitalised due to COVID-19, with three still requiring ventilator support and one on life support. Two of the children admitted during the three-week study period died.

The researchers said they were “cautiously encouraged” by hospital outcomes for the children studied, citing the 4.2 per cent mortality rate for PICU patients compared with published mortality rates of up to 62 per cent among adults admitted to ICUs, as well as lower incidences of respiratory failure.

The study noted that doctors in the New York metropolitan area are seeing what appears to be a new COVID-related syndrome in children. “The idea that COVID-19 is sparing of young people is just false,” said study co-author Lawrence C Kleinman from Rutgers University in the US.

“While children are more likely to get very sick if they have other chronic conditions, including obesity, it is important to note that children without chronic illness are also at risk. Parents need to continue to take the virus seriously,” Kleinman added.

Recently, another study, published in the journal Frontiers in Pediatrics, also revealed that gastrointestinal symptoms such as diarrhoea, coupled with a fever or history of exposure to COVID-19, could indicate coronavirus infection in children.

Healthy Eating Habits in Children Reduces Chances Of Heart Related Risks Later: Study

Healthy children are more likely to have fewer heart risks later

Dear parents, kindly take note. Researchers have found that healthy eating behaviours in childhood may reduce the risk of, overweight, obesity and cardiovascular disease later in life.

Published in the Journal of the American Heart Association, the study focused on providing evidence-based strategies for parents and caregivers to create a healthy food environment for young children that supports the development of positive eating behaviours and the maintenance of a healthy weight in childhood.

Allowing children to choose what and especially how much to eat within an environment composed of healthy options encourages children to develop and eventually take ownership of their decisions about food and may help them develop eating patterns linked to a healthy weight for a lifetime, according to the study authors.

“Parents and caregivers should consider building a positive food environment centred on healthy eating habits, rather than focusing on rigid rules about what and how a child should eat,” said study researcher Alexis C Wood from the Baylor College of Medicine in Houston, US.

The statement suggests that parents and caregivers should be positive role models by creating an environment that demonstrates and supports healthy food choices, rather than an environment focused on controlling children’s choices or highlighting body weight.

Parents and caregivers should encourage children to eat healthy foods by: providing consistent timing for meals, allowing children to select what foods they want to eat from a selection of healthy choices, serving healthy or new foods alongside foods children already enjoy.

Regularly eating new, healthy foods while eating with the child and demonstrating enjoyment of the food, paying attention to a child’s verbal or non-verbal hunger and fullness cues and avoiding pressuring children to eat more than they wish to eat.

The researchers noted that some parents and caregivers may find it challenging to allow children to make their own food decisions, especially if the children become reluctant to try new foods and/or become picky eaters.

These behaviours are common and considered normal in early childhood, ages 1 to 5 years, as children are learning about the tastes and textures of solid foods.

Imposing rigid, authoritarian rules around eating and using tactics such as rewards or punishments may feel like successful tactics in the short term.

In addition, the authoritarian approach has been linked to children being more likely to eat when they are not hungry and eating less healthy foods that are likely higher in calories, which increase the risk of overweight and obesity and/or conditions of disordered eating.

On the other hand, an indulgent approach, where a child is allowed to eat whatever they want whenever they want, does not provide enough boundaries for children to develop healthy eating habits.

“Children’s eating behaviours are influenced by a lot of people in their lives, so ideally, we want the whole family to demonstrate healthy eating habits,” said Wood. (IANS)
