The AMD-powered Frontier supercomputer at Oak Ridge National Laboratory has bagged the top spot on the Top500 list of the world’s fastest supercomputers. The Top500 list also said that the Frontier system is the first true exascale machine with an HPL score of 1.102 Exaflop/s. For two years, the top spot was occupied by the Fugaku system at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan.

Based on the latest HPE Cray EX235a architecture and equipped with AMD EPYC 64C 2GHz processors, the system has 8,730,112 total cores and a power efficiency rating of 52.23 gigaflops/watt. It relies on gigabit ethernet for data transfer.

Deep RNA sequencing of 164 blood samples collected from long-lived families was performed to investigate the expression patterns of circular RNAs (circRNAs). Unlike that observed in previous studies, circRNA expression in long-lived elderly individuals (98.3 ± 3.4 year) did not exhibit an age-accumulating pattern. Based on weighted circRNA co-expression network analysis, we found that longevous elders specifically gained eight but lost seven conserved circRNA-circRNA co-expression modules (c-CCMs) compared with normal elder controls (spouses of offspring of long-lived individuals, age = 59.3 ± 5.8 year). Further analysis showed that these modules were associated with healthy aging-related pathways. These results together suggest an important role of circRNAs in regulating human lifespan extension.

Gravitational-wave scientists propose new method to refine the Hubble Constant—the expansion and age of the universeA team of international scientists, led by the Galician Institute of High Energy Physics (IGFAE) and the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav), has proposed a simple and novel method to bring the accuracy of the Hubble constant measurements down to 2% using a single obse…

Gravitational wave scientists from The University of Western Australia have led the development of a new laser mode sensor with unprecedented precision that will be used to probe the interiors of neutron stars and test fundamental limits of general relativity.

The Computer Security Incident Response Team in Italy issued an urgent alert yesterday to raise awareness about the high risk of cyberattacks against national bodies and organizations on Monday.

Verizon has suffered a data breach. A hacker recently accessed the company’s employee database and stole personally identifiable information about hundreds of its employees. The stolen information includes the full name, phone number, email address, and corporate ID numbers.

According to a Motherboard report, the hacker got access to the Verizon database by tricking an employee to grant them remote access to their corporate computer. They posed as internal support and convinced the victim through social engineering. Once the hacker had access to the database, they launched a script to copy the information.

“These employees are idiots,” the hacker told Motherboard in an online chat. They shared the stolen data, perhaps part of it, with the publication. The report suggests the information is accurate but unclear how up to date. The publication called some of the phone numbers and four people confirmed their full names and email addresses. They also confirmed that they work at Verizon.

SpaceX CEO Elon Musk has revealed the first technical details about the company’s next-generation Starlink ‘Gen2’ satellite design, confirming that it will far outmatch the current generation of satellites by almost every measure.

Speaking in an onsite interview and Starbase tour with YouTuber Tim Dodd (The Everyday Astronaut), Musk – largely unprovoked – revealed that SpaceX has already built at least one functional Starlink Gen2/V2.0 satellite prototype and shipped it to the South Texas Starship factory, where it is currently being stored. More importantly, Musk also provided the first direct specifications for the next-generation spacecraft, stating that each Starlink V2.0 satellite will weigh about 1.25 tons (~2750 lb), measure about seven meters (~23 ft) long, and be almost an order of magnitude more capable than the “Starlink 1” satellites they’ll ultimately supersede.

Almost ten months after SpaceX first revealed its updated plans for a next-generation, 30,000-satellite constellation, those details have confirmed a few key points of speculation about the future of Starlink.

The observable Universe is 92 billion light-years in diameter. These pictures put just how large that is in perspective.

China has to have the capability to identify and destroy SpaceX’s Starlink satellites, according to Chinese military experts in a report released in April. The research, headed by Ren Yuanzhen of the Beijing Institute of Tracking and Telecommunications, was published in the Chinese peer-reviewed journal Modern Defence Technology. The publication inexplicably disappeared from the online version of The South China Morning Post after The South China Morning Post reported on its contents.

David Cowhig, a former US ambassador, was able to complete the translation of the document before it vanished, which allowed him to uncover a number of preventative steps that were suggested to be taken against Starlink. According to the study, China has to “use a mix of soft and hard kill measures to disrupt the operating system of the constellation and deactivate part of the Starlink satellites.”

A recent experiment showed this virtually limitless form of clean power is possible on Earth. Now, one of the most complex energy projects in history aims to make nuclear fusion a reality for the whole planet.
