​New York, Nov 6 (IANS) Poor self-regulation among teens is strongly associated with when one sleeps in relation to their body's natural circadian rhythm, finds a study.

According to the study, published in the journal Pediatrics, daytime sleepiness and being a night owl appear to be more strongly associated with poor self-regulation.

"The results of this study suggest it is not how long you sleep that has the biggest impact on self-regulation, but when you sleep in relation to the body's natural circadian rhythms and how impaired you are by sleepiness," said Judith Owens, Director of the Sleep Center at Boston Children's Hospital, US.

The researchers analysed 2,017 surveys completed by 7th to 12th graders from 19 middle and high schools, where students completed questionnaires about sleep and self-regulation, including cognitive aspects, behavioural aspect and emotional aspects.

Nearly 22 per cent of the students reported sleeping less than seven hours on school nights.

Sleep duration, daytime sleepiness and chronotype were clearly interconnected -- night owls slept less on school nights and were subsequently sleepier in the daytime, as were those who slept for fewer hours.

But when the researchers examined all three aspects of sleep and adjusted for age, socio-demographic factors and mental health conditions like attention deficit hyperactivity disorder (ADHD), depression and anxiety, it was daytime sleepiness and "night owl" tendencies that independently predicted impaired self-regulation -- while sleep duration did not.

Sleepier adolescents reported significantly worse self-regulation, as did teens who tended to be "night owls" rather than "morning larks".

The findings held for all types of self-regulation but were most robust for cognitive and emotional aspects.

"The misalignment or mismatch between early school start times and teens' circadian rhythms -- which normally shift later with puberty -- may worsen self-regulation or so-called executive functioning," Owens added.

​London, Nov 6 (IANS) Music therapy may help to reduce depression in children and adolescents with behavioural and emotional problems, finds a study.

The researchers involved 251 children and young people for the study and found that children and young persons, aged 8-16 years, who received music therapy had significantly improved self-esteem and significantly reduced depression compared with those who received treatment without music therapy.

The study published in Journal of Child Psychology and Psychiatry also found that young people aged 13 and over who received music therapy had improved communicative and interactive skills, compared to those who received usual care options alone. Music therapy also improved social functioning over time in all age groups.

For the study, the children were divided into two groups -- 128 underwent the usual care options, while 123 were assigned to music therapy in addition to usual care. All were being treated for emotional, developmental or behavioural problems.

"This study is hugely significant in terms of determining effective treatments for children and young people with behavioural problems and mental health needs," said Sam Porter, Professor at the Bournemouth University, Britain.

"The findings contained in our report should be considered by healthcare providers and commissioners when making decisions about the sort of care for young people that they wish to support," he said. 

"Music therapy has often been used with children and young people with particular mental health needs, but this is the first time its effectiveness has been shown by a definitive randomised controlled trail in a clinical setting," said Ciara Reilly, Chief Executive of Every Day Harmony.

​London, Nov 5 (IANS) Scientists at Disney Research have developed a 360-degree virtual reality application that enables users to enhance their experience by adjusting feel effects - for instance, a light sprinkle or a heavy downpour - to complement the visuals.

Toronto, Nov 25 (IANS) Researchers have designed a new software that can safeguard data even when the computer is in sleep mode.

The powerful new software -- Hypnoguard -- was designed to protect "data-in-sleep".

​Washington, Nov 5 (IANS) NASA has said its Magnetospheric Multiscale mission, or MMS -- that is giving scientists new insight into Earths magnetosphere -- now holds the Guinness World Record for highest altitude fix of a GPS signal.

Operating in a highly elliptical orbit around Earth, the MMS satellites set the record at 70,006.4 kilometres above the surface, the US space agency said on Friday.

The four MMS spacecraft incorporate GPS measurements into their precise tracking systems, which require extremely sensitive position and orbit calculations to guide tight flying formations.

Earlier this year, MMS achieved the closest flying separation of a multi-spacecraft formation with only about seven kilometres between the four satellites. 

When MMS is not breaking records, it conducts ground-breaking science, NASA said.

Still in the first year of its prime mission, MMS is giving scientists new insight into Earth's magnetosphere. 

The mission uses four individual satellites that fly in a pyramid formation to map magnetic reconnection - a process that occurs as the sun and Earth's magnetic fields interact. 

Precise GPS tracking allows the satellites to maintain a tight formation and obtain high resolution three-dimensional observations.

Understanding the causes of magnetic reconnection is important for understanding phenomena around the universe from auroras on Earth, to flares on the surface of the sun, and even to areas surrounding black holes. 

Shanghai, Nov 5 (IANS) With the internet taking on an industrial dimension whereby new equipment and other technologies are transforming the way goods are produced, industrial innovation must integrate multiple digital concepts to revolutionise existing processes, top executives of 3D software major Dassault Systemes said here at an event.

Digital technology can drive the industrial (r)evolution 4.0 -- innovation programmes to reduce manufacturing costs, increase efficiencies and sustainability, inspire creativity and generate new business models, the French technology company demonstrated at its two-day "Manufacturing in the Age of Experience" event that concluded on Friday.

"Digital's most visible value is to increase productivity and competitiveness, but its true power is the imagination. Manufacturers that succeed will be those that will create a world which does not yet exist," said Pascal Daloz, Executive Vice President, Brands and Corporate Development, Dassault Systemes. 

"The digital factory is not only virtual, connected and automated, but is above all an execution system, where men's skills are turned to innovation, performance, quality and continuous change," Daloz said.

"The virtual becomes constitutive of the products themselves. As a consequence, the value is migrating to the cloud services where data are a strategic asset for the industry to reinvent itself," Daloz noted.

The event highlighted how the digital makeover of the manufacturing sector is essential for creating a dynamic, holistic and more sustainable production model that results in a better consumer experience.

Dassault Systemes provides "3DEXPERIENCE" universes for collaboration and innovation to implement innovative strategies in supply and demand.

The 3DEXPERIENCE platform features virtual design, simulation, manufacturing and collaboration applications in a digital environment that integrate products, processes and supply chains, and offer a federated view of a manufacturer's business in real time.

During the plenary session of the even, top brand leaders of the compnay gave presentations on virtualising the industry value chain 

Top officials from Airbus Helicopters, Doosan Infracore and Honda Motor also shared customer case stories on manufacturing transformation and success.

Dassault Systemes is focused on developing technologies and solutions that propel digital transformation in industries ranging from aerospace to life sciences.
