Researchers have detected a strange repeating rhythm of Fast Radio Bursts (FRBs) emanating from an unknown source outside our galaxy, 500 million light-years away.
Fast radio bursts, or FRBs, are short, intense flashes of radio waves that are thought to be the product of small, distant, extremely dense objects, though exactly what those objects might be is a longstanding mystery in astrophysics.
FRBs typically last a few milliseconds, during which time they can outshine entire galaxies. Since the first FRB was observed in 2007, astronomers have cataloged over 100 fast radio bursts from distant sources scattered across the universe, outside our own galaxy.

Now astronomers have started to find bursts repeating in a pattern, where they seem to switch off and on in a predictable pattern. The latest discovery, published in the journal Nature, sends out random bursts of radio waves over a four-day window, and then goes quiet for 12 days, before beginning again.
Researchers watched the bursts for more than 500 days, noting that the 16-day pattern occurred consistently over that time, making it the most definitive pattern yet seen.
“This FRB we’re reporting now is like clockwork,” said study researcher Kiyoshi Masui from Massachusetts Institute of Technology (MIT) in the US.
“It’s the most definitive pattern we’ve seen from one of these sources. And it’s a big clue that we can use to start hunting down the physics of what’s causing these bright flashes, which nobody really understands,” Masui added.
The latest FRBs were picked up by CHIME, which was the first to pick up signals of the new periodic FRB source. In 2017, CHIME was erected at the Dominion Radio Astrophysical Observatory in British Columbia, where it quickly began detecting fast radio bursts from galaxies across the universe, billions of light-years outside our galaxy.
CHIME consists of four large antennas, each about the size and shape of a snowboarding half-pipe, and is designed with no moving parts. Rather than swiveling to focus on different parts of the sky, CHIME stares fixedly at the entire sky, using digital signal processing to pinpoint the region of space where incoming radio waves are originating.
From September 2018 to February 2020, CHIME picked out 38 fast radio bursts from a single source, FRB 180916. J0158+65, which the astronomers traced to a star-churning region on the outskirts of a massive spiral galaxy, 500 million light-years from Earth.
The source is the most active FRB source that CHIME has yet detected, and until recently it was the closest FRB source to Earth. As the researchers plotted each of the 38 bursts over time, a pattern began to emerge: One or two bursts would occur over four days, followed by a 12-day period without any bursts, after which the pattern would repeat.
This 16-day cycle occurred again and again over the 500 days that they observed the source.
“These periodic bursts are something that we’ve never seen before, and it’s a new phenomenon in astrophysics,” Masui said.
The researchers noted that the blasts could also be the result of a binary system such as a neutron star orbiting around another neutron star or black hole. The pattern could be the result of the orbit between, and the interaction between the two objects, which would explain their regular pattern, they concluded. (IANS)
Amitabh Bachchan is adored by the public for his unforgettable on-screen performances as well as his magnetic demeanour. Not only do fans love Amitabh Bachchan's outstanding performance, but the actor's heartwarming words are also highly regarded. A much moved Amitabh Bachchan, during his speech to the crowd of over 80,000 people at the Reliance Industries' annual event, said that the legacy left by Dhirubhai has had a positive impact on millions of people's lives worldwide.
When Bollywood superstar Amitabh Bachchan became bankrupt in the late 1990s, Dhirubhai Ambani stepped forward to give him financial assistance. In his speech, Bachchan remembered that Dhirubhai had sent Anil Ambani to offer him financial assistance during the crisis, which he had respectfully declined. Lenders began knocking on his door, losses mounted, and his bank account dwindled to nothing. He said, "Dhirubhai's money might have gotten me out of the problem quickly. However, I respectfully declined his offer and gradually began to find work again, which let me pay off my debt."

Later, after Bachchan had recovered from the bankruptcy, one day he was invited to an event at Dhirubhai's residence; Bachchan added, "Dhirubhai was standing and having a chat with his industrialist friends when he saw me there, he called me, firstly I felt shy even to present myself in front of such big industrialists but then, I went there, and Dhirubhai declared in front of all of them that 'This young man had fallen but managed to get back up on his own, I have a lot of respect for him because of that.' Those words of his were worth much more to me than any amount of money that he could have offered me."
It was the "Reliance Family Day" event and was attended by members of the Ambani family from all generations. The event commemorated the company's 40-year journey since its inception. It also celebrated the 85th birthday of the late Dhirubhai Ambani, RILs (Reliance Industries Limited) founder.

In comparison to adults, children are prone to getting traumatized by troubling events easily, and this makes it important for parents to help their children when the times are tough. It could be a brutal accident, an unprecedented pandemic, a violent crime, or other disasters but with the right parental support, children have a higher chance of coming out stronger from an awful situation.
Anuja Kapur, Psychologist shares few tips wherein you can assist your child when tough times comes calling:
Every child responds differently to disturbing events: What children feel about a current disaster in their life and how they react to it can come and go in waves. Children can act moody and withdrawn at times, struck with sorrow and fear at other times. There's no absolute "right" or "wrong" way to feel after a traumatic event so make sure not to dictate what your child or how your child should feel and react to the event.

Encourage your child to be transparent: Just make sure you let your child know that whatever feelings they're experiencing is normal. The unpleasantness will pass if your child opens up about it and that the phase is temporary. While many teens may be reluctant to talk about their feelings with a parent, encourage them to confide in another trusted adult such as a family friend, relative, or a counselor and teacher. It's important to talkeeven if it's not with you.

Deter your child from reliving the disturbing event: Dwelling over, watching the footage, or imagining the event can be overwhelmingly stressful for children and this stress can even block their nervous system. However, to negate such things from happening encourage activities that keep your child's mind occupied so they're not obsessive about the event. You could encourage your children to read, play games together, or simply watch an uplifting movie.

Cocoon your child with warmth: In order to reassure your child that they are safe with you and feel secure, that the worst is over your physical affection is important in making them feel safe again. Teens may try to be tough through it and avoid being held, but they still need the proximity.

Maintain routines. Establishing a predictable structure and schedule for your child's life can help to make the world seem more stable again. Try to maintain regular times for meals, homework, and family activities. Make sure your child accommodates time and space for rest, play, and fun. Keeping up with a schedule can help countercheck the obnoxious feeling of stress and worry in children about the future being dark, hopeless, and unpredictable.

Acknowledge and validate your child's concerns. The disastrous events in life may give place to unrelated fright and concerns in your child. However, understanding and accepting your child's present state is a comfort for the child. If at any point the child blames himself for the event make sure to make it clear and crisp the event was not their fault, you love them, and it's okay for them to feel upset, angry, or scared but not guilty.

Irrespective of the age of your child, it is vital for parents to offer that extra support and assistance following an unsettling event. The traumatic event may bring up unrelated fears and issues in your child. However, by accepting their thoughts and replacing their fear with your love and direction, the ominous feelings will start to fade away. Eventually, the child will be able to return to a normal and healthy life. (IANS/ MBI)

The European Commission, the executive arm of the European Union (EU), has announced plans for smartphone and other electronics manufacturers to fit a common USB-C charging port on their devices in an effort to reduce waste. In addition to phones, the rules will apply to other devices like tablets, headphones, portable speakers, videogame consoles, and cameras, reports The Verge. The decision will have a huge impact on Apple, as the company still uses its own Lightning connector to charge iPhones. The proposals only cover devices using wired, not wireless and a USB-C port is only mandatory for devices that charge using a cable.

"Chargers power all our most essential electronic devices. With more and more devices, more and more chargers are sold that are not interchangeable or not necessary. We are putting an end to that," the report quoted EU commissioner Thierry Breton as saying.
The Commission also wants to unbundle the sale of chargers from the sale of electronic devices, which it says will improve the consumers' convenience. "With our proposal, European consumers will be able to use a single charger for all their portable electronics - an important step to increase convenience and reduce waste." In addition, the Commission will require manufacturers to provide relevant information about charging performance. (IANS/MBI)
