What happens if you don’t put your phone on flight mode during flight?

KATHMANDU — Airlines prescribe travelers change their phones to flight mode during a flight but do you know the reasons behind it ?

If you don’t, experts have now unveiled what REALLY happens if you don’t do that.

It’s commonly believed that a device’s signal can interfere with a plane’s electrical and telecommunications systems but can they cause a crash?

According to MailOnline Travel, now experts can unveil reality behind the prevalent view and discovered precisely what happens, when you don’t put your device on flight mode.

Writing on a blog post for the site AirlineUpdates, a pilot revealed that although mobiles can cause audible interference with the aircraft’s radios, but it’s rare.

The pilot continued: “You’ve probably heard this interference yourself when a phone is set near a speaker. It sounds like a ‘dit-dit-dit-dit’ tone and it’s pretty annoying.”

In fact, the most likely reason for airlines asking passengers to put their devices on flight mode is to avoid annoying the pilots and air traffic controllers with awful sounds.

Despite some passengers believing their phones could bring the plane down, experts claim modern technology is safe and reliable and there’s no evidence electronics have ever caused a crash.

Airline workers experience the same sort of unpleasant sounds that we do if a mobile phone is too close to a set of speakers.

If a plane makes 50 journeys, the interference occurs only twice, on average, over that period of time and often this can be because of cabin crew member’s phones.

But, if there are repeated interference, it can cause the pilot or crew to miss a crucial radio call from air traffic control.

Now, some international airlines are introducing telecommunication base stations that operate at very low power and designed not to interfere with crew’s signals.

KATHMANDU — In an incredible development that could possibly go a long way in medical practices, scientists in California are working on a way to reduce organ transplants and rejections: Growing embryos in sheep and pigs containing human patients’ cells.

In a transplant breakthrough, scientists at the University of California said they have achieved sheep embryos in which around one in every 10,000 cells was human, according to UPI report.

The researchers presented preliminary findings Saturday at the American Association for the Advancement of Science’s annual meeting in Austin, Texas.

The new finding paves way for genetically tailoring the organs to be compatible with the immune system of the patient receiving them, thus removing the possibility of rejection, the report said.

The hybrid embryos contain both human and sheep cells and were created in an early step toward growing human organs in farm animals before transplanting them into patients.

Last year, the same researchers introduced human stem cells into early pig embryos, producing embryos with about one in every 100,000 cells being human.

The experiment began with Hiro Nakauchi, from the University of Tokyo, who grew a mouse with a rat pancreas and a rat with a mouse pancreas.

When cells from the rat-grown mouse pancreas were transplanted into a diabetic mouse, they made enough insulin to cure the condition without being rejected.

Mice and rats are different types of rodents with the former having thin slightly hairy tails, while rats have thicker hairless scaly tails.

“The next step was to move into large animals,” Nakauchi said. Since this was prohibited in Japan, he moved to the Stanford University in the US.

Nakauchi’s rodent work has demonstrated that you can “grow organs in a different species and cure a disease without [suppressing the immune system],” added co-researcher Pablo Ross, Professor at from the University of California, Davis.

“We are working together to translate the technology into humans, to solve the terrible shortage of organs for transplantation. In the US, 20 people die every day because they cannot get the organs they need,” Ross explained.
