Iftar trip turns tragic: 6 of a family die as car rams into tree; baby thrown out to safety

Bengaluru, Jun 7: An eminent scientist on Sunday suggested a shift system in schools to prevent spread of the coronavirus and continuing with online classes with focus on project-based learning in a big way to promote creativity.

Former Director General of the Defence Research and Development Organisation (DRDO) V K Saraswat supported the idea of online teaching in the absence of regular classes in view of closure of schools due to the COVID-19 pandemic.

But, he said it should be organised in far better and more interactive ways so that delivery of knowledge can be better. The NITI Aayog member stressed the need for schools to have a strategy when they reopen keeping in mind the safety of students.

May be they will have to organise shifts so that within the same space they can handle the students; May be they will have to employ more teachers, and they can run two shifts. "May be half the strength in a class can come in the morning and others in the afternoon.

Or students of first to sixth standard can come in the morning and seventh to tenth can come in the afternoon, Saraswat told PTI. Reopening strategy will have to be worked out by the education department, added the former Chief Scientific Advisor to the Defence Minister.

Along with normal classes, online education should be continued as a regular system in future, and promoted in a big way because that is the way technology is going to help delivery of knowledge, he added. Saraswat also raised the pitch for reforms in the education sector, saying India is facing the problem of rote learning.

Rote learning has to give way for more project-based teaching, he underlined. Children should be made to work on projects at home and that can be done online. That will also support the changeover from rote learning to creative learning.

I personally believe the education delivery system -- primary, secondary and college levels -- has to be completely changed because creativity in India is less and creativity would come only if we replace rote learning with project-based learning, Saraswat said.

On some academics holding the view that the marks-based model is killing the education system in India as it does not promote creativity, he said evaluation of any outcome is important. Even when we perform in our normal way, evaluation cannot be replaced.

Otherwise, you cant find out how much you have succeeded in delivery. Certainly evaluation cannot be dispensed with. He did not agree with some experts, who favoured a single, uniform system for school education in India by dispensing with CBSE, ICSE and state boards. I am not for normalising everything in life.

I personally believe variety should be there. This concept of one kind of a system is okay for a Communist society, society which was trying to drive everybody like a herd, he said.

Creativity comes with variety, and there is nothing wrong in having different kinds of education system, but one thing which is important is we have to integrate vocational training as part of the education curriculum," Saraswat said. Vocational part cannot be kept away from the education system, he added.

Washington D.C., May 8: The prime time for brain development in a child's life is the first year, where the infant spends most of the time asleep. It is the time when neural connections form and sensory memories are encoded.

However, when sleep is disrupted, as occurs more often among children with autism, brain development may be affected, too.

New research led by the University of Washington finds that sleep problems in a baby's first 12 months may not only precede an autism diagnosis but also may be associated with altered growth trajectory in a key part of the brain, the hippocampus.

The study, which was published in the American Journal of Psychiatry, researchers report that in a sample of more than 400 taken of 6- to 12-month-old infants, those who were later diagnosed with autism were more likely to have had difficulty falling asleep.

It also states that this sleep difficulty was associated with altered growth trajectories in the hippocampus.

"The hippocampus is critical for learning and memory, and changes in the size of the hippocampus have been associated with poor sleep in adults and older children.

As many as 80 per cent of the children with autism spectrum disorder have sleep problems," said Annette Estes, director of the UW Autism Center and senior author of the study.

"In our clinical experience, parents have a lot of concerns about their children's sleep, and in our work on early autism intervention, we observed that sleep problems were holding children and families back," added Estes, who is also a UW professor of speech and hearing sciences.

"It could be that altered sleep is part-and-parcel of autism for some children. One clue is that behavioural interventions to improve sleep don't work for all children with autism, even when their parents are doing everything just right. This suggests that there may be a biological component to sleep problems for some children with autism," said Estes.

To consider links among sleep, brain development, and autism, researchers at the IBIS Network looked at MRI scans of 432 infants, surveyed parents about sleep patterns, and measured cognitive functioning using a standardized assessment.

At the outset of the study, infants were classified according to their risk for developing autism: Those who were at higher risk of developing autism -- about two-thirds of the study sample -- had an older sibling who had already been diagnosed.

Infant siblings of children with autism have a 20 per cent chance of developing autism spectrum disorder -- a much higher risk than children in the general population.

In the current study, 127 of the 432 infants were identified as "low risk" at the time the MRI scans were taken because they had no family history of autism.

They later evaluated all the participants at 24 months of age to determine whether they had developed autism. Of the roughly 300 children originally considered "high familial risk," 71 were diagnosed with autism spectrum disorder at that age.

Problems with sleep were more common among the infants later diagnosed with an autism spectrum disorder, as were larger hippocampi. No other subcortical brain structures were affected, including the amygdala, which is responsible for certain emotions and aspects of memory, or the thalamus, a signal transmitter from the spinal cord to the cerebral cortex.

The authors note that while parents reported more sleep difficulties among infants who developed autism compared to those who did not, the differences were very subtle and only observed when looking at group averages across hundreds of infants.

Sleep patterns in the first years of life change rapidly as infants transition from sleeping around the clock to a more adult-like sleep/wake cycle. Until further research is completed, Estes said, it is not possible to interpret challenges with sleep as an early sign of increased risk for autism.

Bengaluru, May 15: There is no trace of community spread of COVID-19 pandemic in Karnataka due to the strict measures taken by the State Government, Medical Education Minister Dr K Sudhakar said on Friday.

All those tested positive for the virus here have arrived from other states and are currently being treated in quarantine centres, he tweeted.

Over 25 per cent of the COVID-19 positive cases, which were detected in the state, were related to those who had either come from abroad or other states, and only about 7 per cent cases were associated with the influenza-like diseases, his tweet further read.
