An anonymous reader writes: The RATAN-600 radio telescope in Zelenchukskaya, Russia has detected a strong signal around 11 GHz (which is very unlikely to be naturally-caused) coming from HD164595, a star nearly identical in mass to the Sun and located about 95 light years from Earth. The system is known to have at least one planet. If the signal were isotropic, it would seem to indicate a Kardashev Type II civilization. While it is too early to draw any conclusions, the discovery will be discussed at an upcoming SETI committee meeting on September 27th. According to Paul Gilster, author of the Centauri Dreams website, “No one is claiming that this is the work of an extraterrestrial civilization, but it is certainly worth further study. Working out the strength of the signal, the researchers say that if it came from an isotropic beacon, it would be of a power possible only for a Kardashev Type II civilization. If it were a narrow beam signal focused on our Solar System, it would be of a power available to a Kardashev Type I civilization. The possibility of noise of one form or another cannot be ruled out, and researchers in Paris led by Jean Schneider are considering the possible microlensing of a background source by HD164595. But the signal is provocative enough that the RATAN-600 researchers are calling for permanent monitoring of this target.”

An anonymous reader quotes a report from BBC: New evidence suggests that the famous fossilized human ancestor dubbed “Lucy” by scientists died falling from a great height — probably out of a tree. CT scans have shown injuries to her bones similar to those suffered by modern humans in similar falls. The 3.2 million-year-old hominin was found on a treed flood plain, making a branch her most likely final perch. It bolsters the view that her species — Australopithecus afarensis — spent at least some of its life in the trees. Writing in the journal Nature, researchers from the U.S. and Ethiopia describe a “vertical deceleration event” which they argue caused Lucy’s death. In particular they point to a crushed shoulder joint, of the sort seen when we humans reach out our arms to break a fall, as well as fractures of the ankle, leg bones, pelvis, ribs, vertebrae, arm, jaw and skull. Discovered in Ethiopia’s Afar region in 1974, Lucy’s 40%-complete skeleton is one of the world’s best known fossils. She was around 1.1m (3ft 7in) tall and is thought to have been a young adult when she died. Her species, Australopithecus afarensis, shows signs of having walked upright on the ground and had lost her ancestors’ ape-like, grasping feet — but also had an upper body well-suited to climbing. The bones of this well-studied skeleton are in fact laced with fractures, like most fossils. By peering inside the bones in minute detail, the scanner showed that several of the fractures were “greenstick” breaks. The bone had bent and snapped like a twig: something that only happens to healthy, living bones. “The Ethiopian ministry has agreed to release 3D files of Lucy’s right shoulder and her left knee. So anyone with an interest in this can print Lucy out and evaluate these fractures, and our hypothesis, for themsleves.” You can find the files here.

Gamoid writes: The venerable C programming language hit a 15-year low on the TIOBE Index, perhaps because more mobile- and web-friendly languages like Swift and Go are starting to eat its lunch. “The C programming language has a score of 11.303%, which is its lowest score ever since we started the TIOBE index back in 2001,” writes Paul Jansen, manager of TIOBE Index. With that said, C is still the second most popular programming language in the world, behind only Java. Also worth noting as mentioned by Matt Weinberger via Business Insider, “C doesn’t currently have a major corporate sponsor; Oracle makes a lot of money from Java; Apple pushes both Swift and Objective-C for building iPhone apps. But no big tech company is getting on stage and pushing C as the future of development. So C’s problems could be marketing as much as anything.”

Tesla is planning to further restrict its Autopilot mode via a v8.0 software update that will make it much harder for drivers to ignore safety alerts. Tesla’s Autopilot currently issues alerts on the dashboard “reading Hold Steering Wheel and the driver has to apply pressure on the wheel to make it go away,” reports Electrek. “If you quickly respond to those alerts, the Autopilot’s Autosteer and Traffic Aware Cruise Control (TACC) do not disengage.” The system will disengage if you ignore those warnings for too long. Electrek reports: “Now we learn that Tesla is about to introduce a new restriction with the upcoming v8.0 software update to give more weight to the alerts. According to sources familiar with the Autopilot program, Tesla will add a safety restriction that will result in not only the Autopilot disengaging after alerts are repeatedly ignored, but also blocking the driver from re-engaging the feature after it was automatically disengaged. The driver will not be able to reactivate the Autopilot until the car is stopped and put in ‘Park.’ So far, it looks like it would only affect the Autosteer feature of the Autopilot and TACC would still be available for the duration of the drive. The goal of the new restriction appears to be to encourage Tesla owners to respond to the visual alert and not to ignore them.”
