Light from smartphones may lessen your sleep quality

Houston, Jul 29: Artificial light emitted from digital devices such smartphones and tablets could reduce the quality of your sleep, a study has warned.

The largest source of blue light is sunlight, but it is also found in most LED-based devices. Blue light boosts alertness and regulates our internal body clock, or circadian rhythm, that tells our bodies when to sleep.

This artificial light activates photoreceptors called intrinsically photosensitive retinal ganglion cells (ipRGCs), which suppresses melatonin, the hormone that signals your body that it is time to sleep.

"The most important takeaway is that blue light at night time really does decrease sleep quality. Sleep is very important for the regeneration of many functions in our body," said Lisa Ostrin, assistant professor at University of Houston in the US.

In the study, participants, aged between 17 and 42, wore short wavelength-blocking glasses three hours before bedtime for two weeks, while still performing their nightly digital routine.

Results showed about a 58 per cent increase in their night time melatonin levels.

"Those levels are even higher than increases from over- the-counter melatonin supplements," said Ostrin, who led the study published in Ophthalmic & Physiological Optics.

Wearing activity and sleep monitors 24 hours a day, the 22 study participants also reported sleeping better, falling asleep faster, and even increased their sleep duration by 24 minutes a night, according to Ostrin.

Ostrin recommends limiting screen time, applying screen filters, wearing computer glasses that block blue light, or use anti-reflective lenses to offset the effects of artificial light at nighttime.

Some devices even include night mode settings that limit blue light exposure.

"By using blue blocking glasses we are decreasing input to the photoreceptors, so we can improve sleep and still continue to use our devices.

That is nice, because we can still be productive at night," Ostrin added.

Mangaluru, April 30: The victim of the tragic mob lynching in Mangaluru, 36-year-old Ashraf, was assaulted for nearly two hours before his body was abandoned at the crime scene, according to sources. The incident took place near a local cricket match venue in Kudupu on April 28. The exact motive behind the attack remains under investigation. Ashraf had suffered multiple severe internal injuries, which led to his death.

Ashraf, originally from Pulpalli village in Sultan Bathery taluk, Wayanad district, Kerala, had been living in Mangaluru for the past month as a manual labourer. 

He was known to have a mild mental disability, which had caused him to wander around different areas. Abdul Jabbar, Ashraf’s brother, confirmed that Ashraf was unmarried and had no affiliations with any organization. "We had been treating his health issues for years, but his condition never fully improved," Jabbar shared. 

Despite his mental health challenges, Ashraf frequently visited family in Kerala and maintained regular contact with his brother, who provided him with essentials, including a mobile phone.

The police had initially registered the incident as an unnatural death under suspicious circumstances. However, following the autopsy, the case was reclassified as mob lynching after it was confirmed that Ashraf died from internal injuries caused by strong blows, compounded by shock and the lack of medical intervention.

In connection with the incident, 20 men have been arrested so far, with 25 suspects believed to be involved. The first person to assault Ashraf is thought to be 26-year-old autorickshaw driver T Sachin from Kudupu. Police have invoked several sections of the Bharatiya Nyaya Sanhita (BNS) related to mob violence and culpable homicide. Investigations are ongoing, with authorities collecting witness statements, CCTV footage, and mobile tower data to identify additional suspects.

Abdul Jabbar has assured full cooperation with the police as they continue to investigate the horrific attack.

‘Attempt to cover up’

Meanwhile, the Dakshina Kannada district committee of CPI(M) has accused the Mangaluru City Police Commissionerate of deliberately attempting to cover up the mob lynching. The committee claims that the FIR (First Information Report) filed in this case serves as strong evidence of the police’s efforts to obscure the truth.

“The news of the incident reached the Vamanjoor Police Station within an hour of the incident. Five hours later, police arrived at the crime scene, where they found the brutalized body of the victim. By this time, the details of the incident were clear to the police, and the news had also reached Mangaluru Police Commissioner Anupam Agrawal,” it said.

CPI(M) district secretary Muneer Katipalla alleged that the police apparently tried to weaken and possibly cover up the case due to various factors. Ravindra Nayak, a prominent BJP leader, and Manjunath, both believed to be key figures in the local political circles, are reportedly connected to the attack. The incident drew national attention, and the police were reportedly concerned that the case would cause embarrassment if it became widely known.

As part of the cover-up, Manjunath, who is said to have played a pivotal role in the mob lynching, allegedly filed a report stating that the unidentified body had been found. Despite being fully aware of the details, the police issued a lookout notice, falsely claiming that the victim may have died from falling due to intoxication or a scuffle, with only superficial injuries on his body, said Mr. Katipalla, who believes this was an effort to exonerate the real culprits and avoid further embarrassment for the local authorities.

Dammam, April 26: Chaos and frustration gripped King Fahd International Airport, Dammam, after Air India Express Flight IX484, scheduled to depart for Bengaluru at 8:30 PM on 25 April 2025, was delayed indefinitely due to repeated “technical issues,” leaving over 150 passengers stranded.

According to affected passengers, after an overnight delay, airline officials informed them the technical problems had been “temporarily fixed” and instructed them to board at 1:30 PM (KSA time) on 26 April. However, the situation deteriorated further when the aircraft taxied to the runway — only to halt abruptly on the runway itself, with passengers once again left without clear communication or resolution.

Several passengers provided live updates, expressing grave concerns over safety standards, poor crisis management, and a lack of transparency by the airline’s ground staff.

 “This is not just mismanagement; it is sheer negligence. Passenger lives are being put at serious risk,” said one distressed traveler.

Adding to the growing alarm, Dr P.A. Hameed Padubidri, a noted pro-bono lawyer and social worker who has resided in Saudi Arabia for over two decades, commented:

“I have been in continuous contact with the stranded passengers and am coordinating with the concerned authorities to address this alarming pattern of delays and mismanagement by Air India Express. Passenger rights and safety must be treated with utmost seriousness.”

Dr. Hameed further emphasized: “This marks the third major disruption involving Air India Express flights within a month, raising serious questions about the airline’s operational reliability, aircraft maintenance practices, and overall crisis preparedness.”

He added: “If an aircraft continues to suffer ‘technical issues,’ it clearly indicates systemic negligence. Operating such flights puts the lives of passengers at unacceptable risk. It is deeply shocking and unacceptable.”

Frustrated passengers also pointed out that if this incident had involved other Gulf carriers, passengers would have been promptly provided with food, hotel accommodation, and alternative flight arrangements.

“This exposes a glaring gap in passenger care and service standards,” one stranded traveler noted.

The incident has triggered widespread outrage, with urgent calls for immediate investigation and action by India’s aviation authorities. 

Dr Hameed has appealed to the Ministry of Civil Aviation (MoCA), the Directorate General of Civil Aviation (DGCA), and Union Civil Aviation Minister Shri Ram Mohan Naidu to take action against these recurring failures by Air India Express.

As of the latest update, passengers remain stranded at Dammam Airport, awaiting further instructions, with no clear communication regarding the revised flight schedule.

Karnataka Chief Minister Siddaramaiah on Thursday visited the residence of 35-year-old Bharat Bhushan, in Mathikere, Bengaluru, who was shot dead in front of his family by terrorists in Pahalgam and paid his final respects.

Offering condolences on behalf of all Kannadigas to Bharat Bhushan, the Chief Minister said it is extremely unfortunate that a young, well-educated man like him became a victim of a terror strike.

He strongly condemned the attack as a barbaric and inhuman act.

To facilitate the safe return of Kannada-speaking individuals stranded in Kashmir and to bring back the mortal remains of the deceased, Labour Minister Santosh Lad and a team of officials were immediately dispatched. So far, 175 Kannadigas have been safely brought back to the state.

“It is the government’s duty to protect Kannadigas in difficult times,” the CM stated.

The Karnataka government has announced a compensation of Rs 10 lakh each to the families of the Kannadigas who lost their lives in the recent terror attack in Pahalgam, Kashmir, he added.

“It is the government’s responsibility to completely eradicate terrorism. Our government extends full support to the Centre in eliminating terrorist activities in the country,” CM Siddaramaiah said.

“Killing innocent people in broad daylight and in front of their families is a heinous crime. Similar to the past Pulwama and Balakot incidents, this is a recurrence. Intelligence failure at the Central level may have contributed to this incident as well,” he observed.

The Chief Minister has directed officials to make necessary arrangements for conducting the final rites of Manjunath Rao and Bharat Bhushan with police honours.

The victims from Karnataka include Bharat Bhushan, Manjunath Rao, and Madhusudan (who had settled in Bengaluru, hailing from Andhra Pradesh). Minister for Transport Ramalinga Reddy has met Bharat Bhushan’s family in Bengaluru, while Minister for Education Madhu Bangarappa met Manjunath Rao’s family in Shivamogga and assured them of support. 

Regarding the terror attack in Kashmir, the Chief Minister said the Central government has already initiated certain measures, and the state government will extend complete support for further steps aimed at eliminating terrorism.

Bharat Bhushan had gone on a Kashmir trip with his wife, Dr Sujata, a paediatrician, and toddler son.

The family stated that the gang of terrorists approached him and asked his name. When Bharat told them his name without any fear. The terrorists then asked him to hand over his son to his wife, Sujata. Later, they had asked him whether he was a Hindu or a Muslim. When Bharat said he was a Hindu, he was shot dead.
