Can aliens detect humans by signal leakages from Earth?

Published

on

Researchers have hypothesised in their new study that aliens living on foreign planets need to be technologically more advanced than human beings to detect radio signal leakages from Earth, reported Independent.

The experts simulated the leakage of radio signals from mobile towers and predicted what extraterrestrial life would see on Earth as near as six light years away.

Aliens that may be technologically advanced may not rely on current mobile tower radio signals leakages into space to detect human life, according to the findings published in the journal MNRAS.

The study stated that unless an alien civilisation is much more advanced than humans, “they will find it difficult to detect current levels of mobile tower radio leakage from Earth.”

The researchers also suggested that the detectability of mobile systems on Earth will increase substantially as more powerful broadband systems are adopted across Earth.

The findings of the study also suggested that Earth’s mobile radio signature includes a substantial contribution from Africa, shedding light on the continent’s transition into the digital age after bypassing the landline era.

A co-author Mike Garrett from Manchester University said: “I’ve heard many colleagues suggest that the Earth has become increasingly radio-quiet in recent years — a claim that I always contested — although it’s true we have fewer powerful TV and radio transmitters today, the proliferation of mobile communication around the world is profound.”

“While each system represents relatively low radio powers individually, the integrated spectrum of billions of these devices is substantial,” Dr Garrett said.

“I believe that there’s every chance advanced civilisations are out there, and some may be capable of observing the human-made radio leakage coming from planet Earth,” said Nalini Heeralall-Issur, another author of the study.

While studying further into the matter, scientists hope to examine the signal leakage from powerful civilian and military radars, new digital broadcast systems, Wi-Fi networks, individual mobile handsets and satellites like Elon Musk’s Starlink system.

“Current estimates suggest we will have more than one hundred thousand satellites in low Earth orbit and beyond before the end of the decade,” Dr Heeralall-Issur said.

“The Earth is already anomalously bright in the radio part of the spectrum; if the trend continues, we could become readily detectable by any advanced civilization with the right technology,” she said.

WhatsApp launches bulk channel management functionality

Published

By

WhatsApp has initiated testing of a bulk channel administration feature on iOS for select beta users, enabling the simultaneous selection of many channels, hence enhancing the efficiency of managing following channels.

This essential update enables users to perform bulk activities, including muting many channels simultaneously, designating them as read, and altering notifications. If the chosen channels are muted, users will now have the option to activate notifications. Users can swiftly silence unmuted channels in one action.

Additionally, this feature enables users to unfollow many channels simultaneously, thereby optimizing the process of decluttering their channel list. This change is particularly beneficial for users that oversee numerous subscriptions, as reported by WABetaInfo.

Previously, users were required to manage each channel individually, rendering tasks such as muting or designating channels as read laborious and time-consuming.

The functionality provides enhanced flexibility and control over channel subscriptions, enabling users to efficiently manage notifications. The solution streamlines laborious operations for consumers who subscribe to numerous channels, hence enhancing their entire experience.

Accessibility
The bulk management feature is presently accessible exclusively to a limited number of beta testers who installed the latest WhatsApp beta for iOS using the TestFlight application. WhatsApp, owned by Meta, plans to expand the feature’s availability to a larger user base in the next weeks.

This update demonstrates WhatsApp’s dedication to enhancing user experience by offering a clear and efficient method for managing channels and notifications.

Even after two weeks, the global submarine cable AAA-1 problem that was discovered on January 2 near Qatar has not been fixed, causing sluggish internet connection in several Pakistani towns.

According to a representative for Pakistan Telecommunication Company Limited (PTCL), the issue has affected customers’ capacity to effectively access social media applications and browse the online. Even with initiatives to fix the problem, social networking sites still lag during busy times.

Internet traffic has been redirected via alternate channels to lessen the impact, and more capacity has been set up to stabilize the service.

The PTCL representative promised that “Internet service across the country is operating normally, and there will be no issues with web browsing,” noting that social media applications’ lag is common during

By

In an effort to better prepare young people for opportunities in the quickly changing technology sector, the government has launched a new ICT training portal.

To allow graduates to work with IT companies, Huawei and the Ministry of IT have struck an agreement. This program will give participants hands-on exposure to cutting-edge technology, including cybersecurity and artificial intelligence (AI).

There is now a training program that offers three-year internships to graduates. Huawei has also stated that it is dedicated to helping with training initiatives and contemporary technology.

In order to strengthen technical training, Huawei signed an MOU with COMSATS University Islamabad, further demonstrating its support.

Plans call for establishing training facilities in Karachi and growing the initiative across the country.

These projects funded by the Special Investment Facilitation Council are key to revitalizing Pakistan’s economy and fostering growth in the IT sector.
