The speed demonstrated by the researchers is equivalent to twice the traffic of the entire global Internet.
The first data transmission to exceed 1 petabit per second (Pbit/s) using only a single laser and a single optical chip has been demonstrated by European researchers.
The Aging and Drug Discovery Conference (ARDD) 2022 is pleased to present David Sinclair from Harvard Medical School, who shares new unpublished results from his lab at Harvard Medical School.
Held in Copenhagen at the glorious Ceremonial Hall, this meeting gathers the most prominent figures of the aging and longevity research field, from scientists to clinicians, investors, developers, and everything in between. The fast growth of the conference is evidence of its great quality. In 2022 we had around 400 people on-site, and many others joined through the web.
Todd Humphreys and his team at UT Austin’s Radionavigation Lab believed that the Starlink constellation could offer precise position, navigation, and timing that could serve as a backup to the army’s GPS system.
SpaceX didn’t want to cooperate, so the researchers had to figure things out the hard way.
Microsoft this week confirmed that it inadvertently exposed information related to thousands of customers following a security lapse that left an endpoint publicly accessible over the internet sans any authentication.
“This misconfiguration resulted in the potential for unauthenticated access to some business transaction data corresponding to interactions between Microsoft and prospective customers, such as the planning or potential implementation and provisioning of Microsoft services,” Microsoft said in an alert.
The misconfiguration of the Azure Blob Storage was spotted on September 24, 2022, by cybersecurity company SOCRadar, which termed the leak BlueBleed. Microsoft said it’s in the process of directly notifying impacted customers.
A single computer chip has transmitted a record 1.84 petabits of data per second via a fibre-optic cable – enough bandwidth to download 230 million photographs in that time, and more traffic than travels through the entire internet’s backbone network per second.
Asbjørn Arvad Jørgensen at the Technical University of Denmark in Copenhagen and his colleagues have used a photonic chip – a technology that allows optical components to be built onto computer chips – to divide a stream of data into thousands of separate channels and transmit them all at once over 7.9 kilometres.
First, the team split the data stream into 37 sections, each of which was sent down a separate core of the fibre-optic cable. Next, each of these channels was split into 223 data chunks that existed in individual slices of the electromagnetic spectrum. This “frequency comb” of equidistant spikes of light across the spectrum allowed data to be transmitted in different colours at the same time without interfering with each other, massively increasing the capacity of each core.
The new service will provide 350 Mbps internet, even while taking off and landing.
SpaceX just announced its new Starlink Aviation service, which will allow high-speed in-flight internet that will allow users to make voice calls and stream videogames, according to the company.
The new service promises speeds of up to 350 Mbps for airliners and is aimed mainly at private jet contractors. Earlier this year, SpaceX also announced a partnership with Hawaiian Airlines to bring free WiFi to its flights starting early next year.

Vintage lovers, unite.
Jason Scott, a tech activist has launched a new website named Discmaster, which enables you to find any file among 91.7 million vintage computer files taken from Archive.org.
“The value proposition is the value proposition of any freely accessible research database,” stated Jason Scott in an interview with Ars Technica.
A major internet subsea fiber cable in the South of France was severed yesterday at 20:30 UTC, causing connectivity problems in Europe, Asia, and the United States, including data packet losses and increased website response latency.
Cloud security company Zscaler reports that they made routing adjustments to mitigate the impact. However, users still face problems due to app and content providers routing traffic through the impacted paths.
“Zscaler is working with the content providers to have them influence their portion of the path,” reads a notice from Zscaler.
Researchers have demonstrated a quantum sensor that can power itself using sunlight and an ambient magnetic field, an achievement that could help reduce the energy costs of this energy-hungry technology.
No longer the realm of science fiction, quantum sensors are today used in applications ranging from timekeeping and gravitational-wave detection to nanoscale magnetometry [1]. When making new quantum sensors, most researchers focus on creating devices that are as precise as possible, which typically requires using advanced—energy-hungry—technologies. This high energy consumption can be problematic for sensors designed for use in remote locations on Earth, in space, or in Internet-of-Things sensors that are not connected to mains electricity. To reduce the reliance of quantum sensors on external energy sources, Yunbin Zhu of the University of Science and Technology of China and colleagues now demonstrate a quantum sensor that directly exploits renewable energy sources to get the energy it needs to operate [2].
