Palestinian who grew up in refugee camp wins $1m Global Teacher Prize

New Delhi, Mar 20: An official of South Western Railway has been suspended for "hiding" her son, who returned from Germany and later tested positive for coronavirus.

The youth has been hiding at a railway guest house in Bengaluru, officials said on Friday.

"She (the railway official) not only failed to inform authorities about her son's return from Germany, but also endangered the lives of others by lodging him in a railway rest house near the main Bangalore railway station," railway spokesperson E Vijaya said.

The Assistant Personnel Officer (Traffic) has been suspended, Vijaya said.

The 25-year-old man, who came from Germany via Spain and was instructed to be in home quarantine after he landed at the Kempegowda International Airport in Bengaluru on March 13, later tested positive for Covid-19 on March 18.

"She virtually hid her son to protect her family but endangered all of us," a South Western Railway official said.

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 14: Three youths died of "asphyxiation" when they fell into a pit in the abandoned Kolar gold field mines, where they had gone to allegedly steal iron material early on Thursday, police said.

On Wednesday night, the trio had entered the gold mine in Kolar district, about 100 km from Bengaluru, and fell in the pit after losing balance.

After inhaling the poisonous gas in the pit, they were asphyxiated to death, they said.

"It was a seven hour exercise after which we could bring out two bodies. Work is on to retrieve the third," a police officer told .

Police reached the spot after they were alerted by the accomplices of the deceased.
