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.
Starlink, launched in 2019, had more than 6,300 satellites in service at the beginning of September, out of 12,000 eventually scheduled to be deployed (or even 40,000 according to an announcement of a possible extension of the project).
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.
The company used ‘specially designed equipment’ which included a ‘server,’ an ‘apparatus,’ ‘Wifi’ and ‘sensors,’ but did not specify the exact technology they used.
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.
High-speed free-space data transmission could improve connectivity for space missions.
Researchers at ETH Zurich have achieved record-breaking data transmission speeds using plasmonic modulators, promising advancements in space communication and potential global high-speed internet access. With speeds potentially reaching 1.4 Tbit/s, this technology could change how the world connects.
Scientists have achieved data rates as high as 424Gbit/s across a 53-km (33-mile) turbulent free-space optical link using plasmonic modulators—devices that use special light waves called surface plasmon polaritons to control and modify optical signals. This new research establishes the foundation for high-speed optical communication links that transmit data through open air or space.
“When a new user logs into the server, it immediately stops all ‘noisy’ activities, lying dormant until the server is idle again. After execution, it deletes its binary and continues to run quietly in the background as a service.”
It’s worth noting that some aspects of the campaign were disclosed last month by Cado Security, which detailed an activity cluster that targets internet-exposed Selenium Grid instances with both cryptocurrency mining and proxyjacking software.
Specifically, the fileless perfctl malware has been found to exploit a security flaw in Polkit (CVE-2021–4043, aka PwnKit) to escalate privileges to root and drop a miner called perfcc.
The United Launch Alliance (ULA) is preparing for the second flight of its Vulcan Centaur rocket this week. The mission will see Vulcan carry an inert payload to orbit alongside some experiments and demonstrations and will complete its certification process with the U.S. Space Force (USSF).
SpaceX has delayed missions this week following an off-nominal deorbit burn of a Falcon 9 second stage following the Crew-9 mission. The stage landed in the South Pacific Ocean but outside of the defined reentry corridor. While the team investigates, the company has rescheduled Monday’s planned launch of its OneWeb mission out of Vandenberg to next week, while a Starlink mission will now fly from the Cape this week on Saturday, Oct. 5.
Another Falcon 9 is being prepared to launch the Hera mission for the European Space Agency (ESA) from Florida. With two cubesats onboard, Hera will study the results of NASA’s Double Asteroid Redirection Test (DART) asteroid deflection test, which impacted the Dimorphos asteroid two years ago. The pad at Launch Complex 39A (LC-39A) remains configured for the upcoming Europa Clipper mission, which will fly on a Falcon Heavy next week. Both of these interplanetary missions have launch windows that extend to the end of the month in case of any further delays.
