Brazil's Lula accuses Meta of election interference <br> The campaign of Brazilian President Luiz Inacio Lula da Silva accused tech giant Meta of election interference on Saturday after his social media content was allegedly blocked on the company&#39;s platforms. The leftist leader is seeking a fourth non-consecutive term in the October 25 runoff, where he will face Senator Flavio Bolsonaro, the son of far-right former president Jair Bolsonaro. In a statement, Lula&#39;s campaign reported instances where platforms owned by Meta -- the parent company of Facebook, WhatsApp, and Instagram -- allegedly restricted the distribution of his content. The campaign claimed that in recent days, Meta &quot;prevented President Lula&#39;s profile from promoting Instagram feed posts,&quot; while a post from his official account &quot;experienced an interruption in view counts, which affected its reach.&quot; It also said that prior to last Sunday&#39...

Scientific expedition warns of accelerated glacier melting in NW China's Xinjiang <br> Scientists with China&#39;s Third Xinjiang Scientific Expedition announced on Saturday that they had found more than 24,000 glaciers in the region and warned of accelerating melt there. Xinjiang Uygur Autonomous Region in northwest China ranks first in glacier reserves in the country, followed by Xizang Autonomous Region in southwest China. At a press conference in Urumqi, Xinjiang&#39;s capital, the expedition team released the latest data, saying Xinjiang is home to 24,202 glaciers, covering 23,629 square km. The glacier study is part of a five-year expedition, which was launched in 2021 by the Ministry of Science and Technology. The previous two were conducted in the 1950s and 1980s. The expedition carried out studies on Xinjiang&#39;s ecology, land and agriculture, biodiversity and biological resources, mineral, energy and water resources. Forty-six national research...

New large docodont fossil sheds light on Jurassic mammaliaform diversity

New large docodont fossil sheds light on Jurassic mammaliaform diversity <br> An international team led by Chinese scientists has discovered a new docodont mammaliaform species, the largest known of its kind, in Jurassic strata dating back about 160 million years, enriching scientific understanding of Jurassic mammaliaform diversity. The new species has been named Megacauda sungei. Its fossil specimen, discovered in Ningcheng, north China&#39;s Inner Mongolia Autonomous Region, measures roughly 52 centimeters in length and is estimated to have weighed around 2 kilograms, making it the largest known docodont mammaliaform. Its skull is clearly preserved, its trunk is robust, and its most striking feature is an unusually long, coiled tail. The specimen also retains well-preserved pelvic bones, hind limbs and tail vertebrae, suggesting it was adapted for swimming. Based on its distinctive teeth, researchers believe it could have hunted small animals living in the same envi...

3 in 5 AI models fail terrorism safety tests: Study

3 in 5 AI models fail terrorism safety tests: Study <br> Three in five artificial intelligence (AI) models have failed terrorism safety tests, with models stripped of safeguards consistently providing potentially dangerous information, according to research reported by CBC News on Friday. The study, conducted by the UK-based nonprofit Tech Against Terrorism, evaluated more than 130 AI models using hundreds of requests resembling those a terrorist planning an attack might submit. Researchers found that models modified through a process known as &quot;abliteration,&quot; which removes safety safeguards, failed every test. Meta&#39;s Llama 3.1 8B model scored 97 out of 100 on the organization&#39;s safety benchmark before modification, compared with approximately three afterward. Researchers said the modified model provided detailed responses to requests involving attacks, terrorist financing and radicalization, while its original version refused such reques...

Under new regulations, Turkiye bans children under 15 from social media <br> Turkiye has barred social network providers from offering services to minors under the age of 15, according to new Cyber Security Directorate regulations published on Saturday in the Official Gazette. The regulation said providers &quot;cannot provide services to children who have not reached the age of 15.&quot; Providers must also offer differentiated services and take necessary measures for users 15 and older, according to the regulations, adding that they should consider the minor&rsquo;s best interests and their physical, mental, psychological, social, and emotional development. Age verification must prioritise personal data protection, using methods that determine only whether a user meets the age threshold rather than establishing identity, it added.
