Over 1,700 Ancient Viruses Discovered Hidden in Glaciers

By Sajjad Ali

Scientists have uncovered over 1,700 ancient viruses preserved in glacier ice, some dating back nearly 15,000 years. This discovery, made in ice cores from the Tibetan Plateau, revealed 33 distinct viruses, 28 of which were previously unknown. These viruses have been frozen in time, adapted to survive in extreme, cold environments.

As glaciers melt due to climate change, these ancient pathogens could be released into modern ecosystems, raising concerns about potential risks. While most of these viruses are believed to infect bacteria rather than humans, the possibility of reactivated "zombie pathogens" highlights the need for further research.

Despite the risks, the study of these ancient viruses offers valuable insights into the evolution of life on Earth and may even guide future searches for life on other planets.

World's first successful demonstration of laser communication

World's first successful demonstration of laser communication France's Defense Innovation Agency (AID) and a local company, KaiLabs, claim to have made the first communication between a low-Earth orbit nano satellite and a commercial ground station using lasers. Successfully tested. The project, which will begin with the launch of the Kernos satellite in late 2023, aims to ensure high-quality communications by addressing disruptions caused by turbulence in the Etasphere. Another advantage of this technology is fast data transfer which will help satellites to send large amounts of data to other satellites and ground stations. Optical communication technology such as lasers can transmit 100 times more data to Earth than current radio frequency systems. AID said the technology will enable space laser communications to be used on mobile, land, sea and air platforms. It could also be linked to the future satellite systems of the French Ministry of Defense.

Flaws in the new iPhone 16?

The iPhone 16, which was offered for regular sale at Apple Stores, started experiencing problems with the users. Several iPhone 16 buyers on social networking platform Reddit have complained that Apple's flagship device freezes the phone's touchscreen if space is pressed along with the camera button. A new feature to be added to the iPhone 16, the Camera button allows users to take and control photos without opening the camera app. According to the 9-to-5 Mac, pressing the area near the camera button temporarily pauses all taps, swipes, and other on-screen actions, possibly due to the rejection algorithm offered in iOS.
