WhatsApp Extends Time Limit for ‘Delete for Everyone’

That time window could soon be extended to just over an hour. The new feature is currently being tested on select Android users.



That time window could soon be extended to just over an hour. The new feature is currently being tested on select Android users, and it is unclear how quickly it will be rolled out globally.

WhatsApp will soon give you more time to ‘unsend’ embarrassing messages.The app currently allows users to recall messages up to seven minutes after they have been sent as part of its ‘Delete for Everyone’ tool.

That time window could soon be extended to just over an hour. The new feature is currently being tested on select Android users, and it is unclear how quickly it will be rolled out globally.

As per the Beta version of WhatsApp for Android 2.18.69, WhatsApp will offer a window of 4,096 seconds, i.e. 68 minutes and 16 seconds, to its users to delete a message which they might’ve sent to anyone.

A WABetaInfo report informs of the new extended timeline for the ‘Delete of Everyone’ feature: “You can now delete messages for everyone sent within 4096 seconds that is 68 minutes and 16 seconds.”

It is worth noting that with the duration for ‘Delete for Everyone’ now extended, there is a chance that the recipient might already have read the WhatsApp message by the time it is deleted in a chat.

Along with the extended time period for the feature, the report also mentions that WhatsApp for Android 2.18.67 version has modified icons to stickers.

Given Two Years to Live 56 Years Ago, Stephen Hawking Dies at 76

Living with amyotrophic lateral sclerosis (ALS) for about 55 years, he remarkably defied the average survival rate of two to five years for those with the motor-neuron disease.



English physicist Stephen Hawking, known for his groundbreaking work with black holes and relativity, died today aged 76. Living with amyotrophic lateral sclerosis (ALS) for about 55 years, he remarkably defied the average survival rate of two to five years for those with the motor-neuron disease.

Hawking was regarded as one of the most brilliant theoretical physicists in history. His work on the origins and structure of the universe, from the Big Bang to black holes, revolutionized the field, while his best-selling books have appealed to readers who may not have Hawking’s scientific background.

Like all ‘mere humans’, Hawking, arguably the most celebrated physicist of his era, was proven wrong a many times.

For instance, for a while, he thought that black holes destroyed information, which physics completely disregards.

He also said that Cygnus X-1, an emitter of X-rays over 6,000 light years away, wouldn’t turn out to be a black hole. (It eventually did.)

He thought no one would ever find the Higgs boson, the particle indirectly responsible for the existence of mass in the universe. (Researchers at CERN found it in 2012.)

But that would be akin to nitpicking. Hawking was right more number of times than he was not.

He and the physicist Roger Penrose described singularities, mind-convoluting physical concepts where relativity and quantum mechanics collapse inward on each other—as at the heart of a black hole. It’s the sort of place that no human will ever see first-hand; the event horizon of a black hole smears matter across time and space like cosmic paste. But Hawking’s mind was singular enough to see it, or at least imagine it.

His calculations helped show that as the young universe expanded and grew through inflation, fluctuations at the quantum scale—the smallest possible gradation of matter—became the galaxies we see around us. No human will ever visit another galaxy, and the quantum realm barely waves at us in our technology, but Hawking envisioned them both. And he calculated that black holes could sometimes explode, an image that would vex even the best visual effects wizard.

Early Years:

Stephen William Hawking was born in England on Jan. 8, 1942. He attended University College, Oxford, where he studied physics, despite his father’s urging to focus on medicine. Hawking went on to Cambridge to research cosmology, the study of the universe as a whole.

In early 1963, just shy of his 21st birthday, Hawking was diagnosed with motor neuron disease, more commonly known as Lou Gehrig’s disease or amyotrophic lateral sclerosis (ALS).

He was not expected to live more than two years. Completing his doctorate did not appear likely. Yet, Hawking defied the odds, not only attaining his PhD but also forging new roads into the understanding of the universe in the decades since.

As the disease spread, Hawking became less mobile and began using a wheelchair. Talking grew more challenging and, in 1985, an emergency tracheotomy caused his total loss of speech. A speech-generating device constructed at Cambridge, combined with a software program, served as his electronic voice, allowing Hawking to select his words by moving the muscles in his cheek.

Just before his diagnosis, Hawking met Jane Wilde, and the two were married in 1965. The couple had three children before separating. Hawking remarried in 1995 but divorced in 2006.

Hawking became as much a cultural icon as a scientific one. For a time police suspected his second wife and one-time nurse of abusing him; the events became the basis of an episode of Law and Order: Criminal Intent. He played himself on The Simpsons and was depicted on Family Guyand South Park. Eddie Redmayne played Hawking in a biopic.

The scientist gained popularity outside the academic world and appeared in several TV shows including Red Dwarf and The Big Bang Theory.

His most famous book – A Brief History of Time – has now shot to the top of the Amazon Best Sellers list.

The Motor Neurone Disease Association, of which Prof Hawking had been a patron since 2008, reported that its website had crashed because of an influx of donations to the charity:

Coming in 2022, Foldable Phones!



Foldable phones will be on the market within five years, a member of the Graphene Flagship programme said on Tuesday.

The pan-European research initiative is made up of over 150 academic and industrial institutions across 23 countries, who are tasked with taking graphene out of the lab and on to the market.

Mobiles and wearable tech is one sector the group is targeting because of graphene’s unique properties.

The substance is stronger than steel but thinner than paper, as well as being bendable, stretchable, highly conductive and extremely lightweight.

Researchers from Aachen University in Germany were at Mobile World Congress to display flexible microchips can be used as wireless receivers. They expect phones to be made of the same material by 2023, allowing users to bend their devices and even fold them up.

Another team from Barcelona is developing a neuron sensor that can be embedded onto the brains of patients who have lost the ability to speak. The sensor is designed to translate electrical impulses into words and text that can be sent to a mobile device or computer via a wireless transmitter.

Researchers are also trying to harness graphene’s properties as a pressure sensor, by incorporating it into smart running shoes. Graphene pads in the shoes’ insoles measure the pressure distribution of each step, which is transmitted to a mobile app via Bluetooth, allowing a runner to achieve the most efficient gate.

India to host World Environment Day 2018



India will host the global World Environment Day celebrations on 5 June 2018, the government and the UN jointly announced today.

“India will be a great global host of 2018’s World Environment Day celebrations,” said Erik Solheim, United Nations Under-Secretary-General and Head, UN Environment at the announcement on Monday.

The government has also committed to organizing and promoting the World Environment Day celebrations through a series of engaging activities and events generating strong public interest and participation.

From pan India plastic clean-up drives in public areas, national reserves and forests to simultaneous beach clean-up activities – India will lead the initiative by setting an example.

“India is excited to host the World Environment Day this year on June 5. Indian philosophy and lifestyle have long been rooted in the concept of co-existence with nature. We are committed towards making Planet Earth a cleaner and greener place”, said Dr Harsh Vardhan, Minister of Environment, Forests and Climate Change.

“Beat Plastic Pollution”, the theme for World Environment 2018, urges governments, industry, communities and individuals to come together and explore sustainable alternatives and urgently reduce the production and excessive use of single-use plastic that is polluting our oceans, damaging marine life and threatening human health.

India is emerging as a leader given it has one of the highest recycling rates in the world. It can be instrumental in combating plastic pollution. By hosting World Environment Day 2018, the Indian government is accelerating its leadership on an issue of tremendous magnitude.

World Environment Day is a UN Environment-led global event, the single largest celebration of our environment each year, which takes place on June 5 and is celebrated by thousands of communities worldwide.
