Can aliens detect humans by signal leakages from Earth?

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.

For 18 graduates of the Reko Diq Mining Project, the National University of Technology, Islamabad, has started a training program. These graduates will complete an 18-month on-the-job training program at Barrick’s International Mining Sites after completing a two-month course at NUTECH.

The graduates will acquire proficiency in mining and associated technical domains during the training program. The chosen graduates will also get specific instruction on environmental protection, safety, exploration, and geology.

Along with the development of communication skills, the curriculum will also emphasise the most recent advancements in the mining industry. Barrick’s International Graduate Development Program for 2024 includes the Balochistani graduates.

Additionally, nine Baloch graduates were selected in 2023 and transported to Barrick’s facility in Argentina for on-the-job training.

WhatsApp is implementing a new upgrade to refine the Updates tab interface, hence boosting accessibility for status and channel updates.

WABetaInfo reports that the upgrade introduces expedited shortcuts that streamline the updating of statuses and channels. Users can now select and upload photos and videos directly from the interface, reducing the steps involved in choosing media from the gallery.

The Meta-owned messaging application has also revamped the button for generating text-based status updates and introduced a feature for recording and sharing voice status updates. This offers customers a more expedient method to disseminate text and speech updates without depending on the floating action button.

The revisions correspond with recent modifications to other tabs, ensuring a modernised interface that improves navigation and update creation. WhatsApp is modifying the floating action button to facilitate content sharing within channels.

When selecting the floating action button, users will see several options, including creating status updates, starting new channels, or sharing photos, videos, voice, and text in existing channels. This revamp integrates all content-generating options into a singular section.

The new shortcuts are anticipated to be accessible to a broader user base in the forthcoming weeks. Beta testers can currently access them in the latest WhatsApp beta for Android, version 2.24.26.13, available on the Google Play Store.

Through Chinese expertise, the arrangement, which was made possible by the Special Investment Facilitation Council (SIFC), intends to increase Pakistan’s agricultural output.

The Punjab government and China’s “AI Force Tech” company have inked a memorandum of understanding (MoU) to introduce advanced agricultural machinery during Chief Minister Maryam Nawaz’s visit to China.

Through the use of advanced robotic technology, the MoU seeks to transform Pakistan’s agricultural industry, guarantee economic growth, and boost farmers’ wealth with China’s assistance.

Through the partnership, Pakistan would also have the chance to absorb knowledge about China’s sophisticated farming methods.

In the meantime, plans have been revealed by the Federal Minister of Planning to send 1,000 agricultural experts to China to study contemporary farming methods.

A Chinese business and the Punjab government previously inked an agreement to introduce cutting-edge cancer treatment technologies to Punjab.

Maryam Nawaz signed a Memorandum of Understanding (MoU) with Hygea Medical Technologies while she was in China in order to introduce cutting-edge cancer treatment equipment and techniques to Punjab.

This equipment will make it feasible to treat cancer without the need for chemotherapy or surgery.

Following a meeting with Hygea Medical Technologies President Dr. Luo Fuliang, Maryam Nawaz said the organization has promised expert assistance for the establishment of the Nawaz Sharif Cancer Hospital.

She went on to say that the hospital will work with China to treat cancer patients utilizing the newest equipment and techniques following the agreement.

Maryam Nawaz and a high-level delegation are present. From December 8 to December 15, the chief minister will go to Beijing, Shanghai, Shenzhen, and Guangzhou.

CM Maryam Nawaz is expected to attend a number of conferences, events, and meetings with the goal of enhancing bilateral relations and looking into potential joint ventures in the areas of infrastructure development, technology, agriculture, and governance.
