Scientists Explored Island Cave, Found 1 Million-Year-Old Remnants a Lost World

Slashdot.org - 1 hour 6 min ago

"A spectacular trove of fossils in a discovered in a cave on New Zealand's North Island has given scientists their first glimpse of ancient forest species that lived there more than a million years ago," reports Popular Mechanics: The fossils represent 12 ancient bird species and four frog species, including several previously unknown bird species. Taken together, the fossils paint a picture of an ancient world that looks drastically different than it does today. The discovery also fills in an important gap in scientific understanding of the patterns of extinction that preceded human arrival in New Zealand 750 years ago. The team published a study on the find in Alcheringa: An Australasian Journal of Palaeontology. Trevor Worthy, lead study author and associate professor at Flinders University, said in a statement that "This remarkable find suggests our ancient forests were once home to a diverse group of birds that did not survive the next million years... "For decades, the extinction of New Zealand's birds was viewed primarily through the lens of human arrival 750 years ago. This study proves that natural forces like super-volcanoes and dramatic climate shifts were already sculpting the unique identity of our wildlife over a million years ago."

Cyber-Espionage Group Breached Systems in 37 Nations, Security Researchers Say

Slashdot.org - 2 hours 6 min ago

An anonymous reader shared this report from Bloomberg: An Asian cyber-espionage group has spent the past year breaking into computer systems belonging to governments and critical infrastructure organizations in more than 37 countries, according to the cybersecurity firm Palo Alto Networks, Inc. The state-aligned attackers have infiltrated networks of 70 organizations, including five national law enforcement and border control agencies, according to a new research report from the company. They have also breached three ministries of finance, one country's parliament and a senior elected official in another, the report states. The Santa Clara, California-based firm declined to identify the hackers' country of origin. The spying operation was unusually vast and allowed the hackers to hoover up sensitive information in apparent coordination with geopolitical events, such as diplomatic missions, trade negotiations, political unrest and military actions, according to the report. They used that access to spy on emails, financial dealings and communications about military and police operations, the report states. The hackers also stole information about diplomatic issues, lurking undetected in some systems for months. "They use highly-targeted and tailored fake emails and known, unpatched security flaws to gain access to these networks," said Pete Renals, director of national security programs with Unit 42, the threat intelligence division of Palo Alto Networks.... Palo Alto Networks researchers confirmed that the group successfully accessed and exfiltrated sensitive data from some victims' email servers. Bloomberg writes that according to the cybersecurity firm, this campaign targeted government entities in the Czech Republic and the Ministry of Mines and Energy of Brazil, and also "likely compromised" a device associated with a facility operated by a joint venture between Venezuela's government and an Asian tech firm. The cyberattackers are "also suspected of being active in Germany, Poland, Greece, Italy, Cyprus, Indonesia, Malaysia, Mongolia, Panama, Greece and other countries, according to the report."

Brookhaven Lab Shuts Down Relativistic Heavy Ion Collider (RHIC)

Slashdot.org - 5 hours 6 min ago

2001: "Brookhaven Labs has produced for the first time collisions of gold nuclei at a center of mass energy of 200GeV/nucleon." 2002: "There may be a new type of matter according to researchers at Brookhaven National Laboratory." 2010: The hottest man-made temperatures ever achived were a record 4 trillion degree plasma experiment at Brookhaven National Laboratory in New York... anointed the Guinness record holder." 2023: "Scientists at Brookhaven National Laboratory have uncovered an entirely new kind of quantum entanglement." 2026: On Friday, February 6, "a control room full of scientists, administrators and members of the press gathered" at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab in Upton, New York to witness its final collisions, reports Scientific American: The vibe had been wistful, but the crowd broke into applause as Darío Gil, the Under Secretary for Science at the U.S. Department of Energy, pressed a red button to end the collider's quarter-century saga... "I'm really sad" [said Angelika Drees, a BNL accelerator physicist]. "It was such a beautiful experiment and my research home for 27 years. But we're going to put something even better there." That "something" will be a far more powerful electron-ion collider to further push the frontiers of physics, extend RHIC's legacy and maintain the lab's position as a center of discovery. This successor will be built in part from RHIC's bones, especially from one of its two giant, subterranean storage rings that once held the retiring collider's supply of circulating, near-light speed nuclei...slated for construction over the next decade. [That Electron-Ion Collider, or EIC] will utilize much of RHIC's infrastructure, replacing one of its ion rings with a new ring for cycling electrons. The EIC will use those tiny, fast-flying electrons as tiny knives for slicing open the much larger gold ions. Physicists will get an unrivaled look into the workings of quarks and gluons and yet another chance to grapple with nature's strongest force. "We knew for the EIC to happen, RHIC needed to end," says Wolfram Fischer, who chairs BNL's collider-accelerator department. "It's bittersweet." EIC will be the first new collider built in the US since RHIC. To some, it signifies the country's reentry into a particle physics landscape it has largely ceded to Europe and Asia over the past two decades. "For at least 10 or 15 years," says Abhay Deshpande, BNL's associate laboratory director for nuclear and particle physics, "this will be the number one place in the world for [young physicists] to come." The RHIC was able "to separately send two protons colliding with precisely aligned spins — something that, even today, no other experiment has yet matched," the article points out: During its record-breaking 25-year run, RHIC illuminated nature's thorniest force and its most fundamental constituents. It created the heaviest, most elaborate assemblages of antimatter ever seen. It nearly put to rest a decades-long crisis over the proton's spin. And, of course, it brought physicists closer to the big bang than ever before... When RHIC at last began full operations in 2000, its initial heavy-ion collisions almost immediately pumped out quark-gluon plasma. But demonstrating this beyond a shadow of a doubt proved in some respects more challenging than actually creating the elusive plasma itself, with the case for success strengthening as RHIC's numbers of collisions soared. By 2010 RHIC's scientists were confident enough to declare that the hot soup they'd been studying for a decade was hot and soupy enough to convincingly constitute a quark-gluon plasma. And it was even weirder than they thought. Instead of the gas of quarks and gluons theorists expected, the plasma acted like a swirling liquid unprecedented in nature. It was nearly "perfect," with zero friction, and set a new record for twistiness, or "vorticity." For Paul Mantica, a division director for the Facilities and Project Management Division in the DOE's Office of Nuclear Physics, this was the highlight of RHIC's storied existence. "It was paradigm-changing," he says... Data from the final run (which began nearly a year ago) has already produced yet another discovery: the first-ever direct evidence of "virtual particles" in RHIC's subatomic puffs of quark-gluon plasma, constituting an unprecedented probe of the quantum vacuum. RHIC's last run generated hundreds of petabytes of data, the article points out, meaning its final smash "isn't really the end; even when its collisions stop, its science will live on." But Science News notes RHIC's closure "marks the end for the only particle collider operating in the United States, and the only collider of its kind in the world. Most particle accelerators are unable to steer two particle beams to crash head-on into one another."
