Modern high-speed internet uses light to quickly and reliably transmit large amounts of data through fiber-optic cables, but currently, light signals hit a bottleneck when data processing is necessary. For that, they must convert into electrical signals for processing before further transmission.
Forward-looking: By combining different wireless techniques, UK researchers achieved record-breaking data transmission speeds. The technology achieved 1 Tbps in lab experiments. Now, it only needs to prove itself in commercially viable applications.
A University College London (UCL) team achieved a nearly one terabit per second data transfer speed over a wireless connection. The world record feat opens the doors to future improvements to high-speed wireless. The researchers used a wide range of frequencies in the electromagnetic spectrum, achieving data rates thousands of times faster than typical UK download speeds over 5G networks.
The recently published study describes an ultra-wideband transmission over the air that combines electronic and photonic-assisted signal generation to send 938 Gbps over a 5-150GHz frequency range. The researchers point out that traditional wireless networks use radio frequencies operating below 6GHz, providing an average speed of 100 Megabits per second over 5G.
Would you like to see more applications for Neuralink in the future? Share your thoughts in the comments.
Elon Musk’s brain technology startup, Neuralink, reported that its implant is functioning well in a second trial patient, identified as Alex. This implant is designed to help paralyzed patients control digital devices through thought alone. Unlike the first patient, Noland Arbaugh, who experienced thread retraction issues post-surgery, Alex has not faced similar problems. Neuralink implemented new measures to prevent such complications, including reducing brain motion during surgery. Both patients have been able to use the implant to perform tasks like playing video games, browsing the internet, and even designing 3D objects.
AI-powered misinformation detectors—artificial intelligence tools that identify false or inaccurate online content—have emerged as a potential intervention for helping internet users understand the veracity of the content they view. However, the algorithms used to create these detectors are experimental and largely untested at the scale necessary to be effective on a social media platform.
To support the data generated in Il11ra1-deleted mice on a mixed C57BL6/129 genetic background30 and to more deeply dissect age-related effects, we studied young (3-month-old) and aged (2-year-old) female mice with deletion of Il11 (Il11−/−) on a C57BL6/J background31.
Immunoblots confirmed IL-11 up-regulation across tissues in old age in this additional strain (Fig. 1m). Old female Il11−/− mice had lower body weights and fat mass and preserved lean mass (Fig. 2a–c). The frailty score15 of old female Il11−/− mice was lower than that of old wild-type mice and their body temperatures were mildly increased (Fig. 2d and Extended Data Fig. 5a). Lower frailty scores were largely driven by improvements in tremor, loss of fur colour, gait disorders and vestibular disturbance (Supplementary Table 1). Muscle strength was higher in both young and old Il11−/− mice (a phenomenon that was observed for some other phenotypes) compared with age-matched controls (Fig. 2e and Extended Data Fig. 5b).
Chronic inhibition of mTORC1 with rapamycin can cause glucose intolerance owing to indirect inhibition of mTORC235. It was therefore important to more fully assess the effects of IL-11 inhibition on liver function, metabolism and glucose utilization in old mice. As wild-type mice aged, there were increases in serum AST, ALT, cholesterol and triglycerides, which were collectively mitigated in old Il11−/− mice (Fig. 2f and Extended Data Fig. 5c, d). Glucose tolerance test (GTT) and insulin tolerance test (ITT) profiles of old Il11−/− mice were similar to those of young wild-type mice, whereas GTTs and ITTs of old wild-type mice showed impairment (Fig. 2g and Extended Data Fig. 5e, f). Indexed skeletal muscle mass was greater in both young and old Il11−/− mice compared with the equivalent wild-type mice (Extended Data Fig. 5g).
So, does anyone thinks that perhaps there are too many sats in orbit? what will be when they all deploy? Earth Sky 1956 clear of any sat at least of human origin and after that mayor astronomy problem with sats in orbit.
International competition is intensifying for the deployment of satellite constellations into orbit, notes Statista’s Katharina Buchholz.
Satellite constellations — the most well-known being SpaceX’s Starlink — are designed to provide high-speed global Internet access.

I’ve been having the most insane dreams recently…
Scientists have brought science fiction one step closer to reality by achieving the first two-way communication between individuals during lucid dreaming, Report informs referring to the Daily Mail.
In an experiment that sounds like a scene out of the movie ‘Inception,’ REMspace — a California-based startup that designs technology to enhance sleep and lucid dreaming — reportedly exchanged a message between two people who were asleep.

Imagine a future where indoor wireless communication systems handle skyrocketing data demands and do so with unmatched reliability and speed. Traditional radio frequency (RF) technologies like Wi-Fi and Bluetooth are beginning to struggle, plagued by limited bandwidth and increasing signal congestion.
(NEXSTAR) — The Internet Archive, a popular digital library known for its Wayback Machine, was hacked and suffered a data breach that reportedly exposed 31 million user accounts.
Founder Brewster Kahle confirmed in a post on the social media platform X that a cyberattack on Tuesday knocked the website offline. He also said that usernames, emails, and encrypted passwords had been compromised.
“Services are currently stopped to upgrade internal systems,” Kahle wrote in a Thursday update. “We are working to restore services as quickly and safely as possible. Sorry for this disruption.”
The hack exposed the data of 31 million users as the embattled Wayback Machine maker scrambles to stay online and contain the fallout of digital—and legal—attacks.
