Largest bacterium ever discovered is longer than a housefly

Posted by in category: evolution

Biologists have discovered the largest bacterium ever found, with a single cell measuring a mammoth 2 cm (0.8 in) long. Visible to the naked eye, this new species has some bizarre characteristics that make it like a missing link in the evolution of complex cells like those in humans.

Most species of bacteria measure between one and five micrometers long, but the biggest previously known was Thiomargarita namibiensis, which tops out at 750 micrometers or 0.75 mm. But this newly identified species blows everything else out of the water – its average length is a whopping 9,000 micrometers (0.9 cm/0.4 in), with the largest recorded specimen reaching 2 cm. This single cell is longer than your everyday housefly.

This gigantic size completely upends the accepted scientific understanding of how big bacteria could possibly get. It was long believed that the size of bacteria was limited by the distance that the molecules they exchange with their environment could travel. If nutrients can’t make the journey from their membrane to their interior, and if toxins can’t do the reverse trip, the organism wouldn’t be viable.

Not just China, South Korea is betting big on metaverse too — plans to spend $187 million to build its national ecosystem, form a Digital New Deal

Posted by in categories: education, government

Other than creating experts, the Ministry’s statement detailed three other objects for the future, which include creating an expanded virtual world (translated from Korean). The government also wants the metaverse platform to focus on industrial convergence and lifestyle, using it for growing Korea’s education industry, media and its cities.

Further, the statement also said that content creators will get support from the government’s strategy. The Ministry will also host hackathons, developer events etc. aimed at fostering the country’s metaverse community, while the statement also mentions forming favourable regulatory systems and laws in order to favour the metaverse.

SpaceX Starlink: As dishes go to Ukraine, what to know about the internet service

Posted by in categories: Elon Musk, internet, satellites

Starlink promises high speed and low latency internet access.


On Saturday, CEO Elon Musk posted on his Twitter page that Starlink service is active in Ukraine, with more terminals en route. Previously, Mykhailo Fedorov, vice prime minister of Ukraine, had tweeted to Musk on Saturday, February 26, calling for the tech billionaire to provide some assistance to Ukraine amidst the Russian attack on the country.

Starlink is designed to help people in areas without access to reliable, ground-based internet get online — so long as they have a view of the sky. Starlink promises high-speed and low latency service without relying on expensive ground-based fiber optic cables or local infrastructure. Just point a dish at the sky, and the supplied hardware will connect to the internet using the satellites orbiting above.

Quantum Gravity Sensor Breakthrough Paves Way for Groundbreaking Map of World Under Earth’s Surface

Posted by in categories: quantum physics, security

An object hidden below ground has been located using quantum technology — a long-awaited milestone with profound implications for industry, human knowledge, and national security.

University of Birmingham researchers from the UK National Quantum Technology Hub in Sensors and Timing have reported their achievement in Nature. It is the first in the world for a quantum gravity gradiometer outside of laboratory conditions.

The quantum gravity gradiometer, which was developed under a contract for the Ministry of Defence and in the UKRI-funded Gravity Pioneer project, was used to find a tunnel buried outdoors in real-world conditions one meter below the ground surface. It wins an international race to take the technology outside.

Advanced new GOES-T weather satellite is ‘go’ for launch on March 1, NASA says

Posted by in category: satellites

Once it’s in space, it’ll be known as GOES-18.


“A big part of the GOES-R [series] mission is actually doing solar observations,” said Pam Sullivan, NOAA’s GOES-R program director.

Before GOES-T can begin its weather-watching mission, it does have to reach space. To do that, it will need good weather.
