Ice age camel bones found in Yukon redraw species’ lineage

DAWSON CITY, Yukon: Miners in northwestern Canada have discovered ice age camel bones whose DNA is forcing scientists to redraw the family tree of the now-extinct species.
Grant Zazula, a paleontologist with the Yukon’s Department of Tourism and Culture, says three fossils recovered from a gold mine in 2008 are the first western camel bones found in the territory or Alaska in decades.
Scientists had believed western camels that once lived in North America were related to llamas and alpacas common to South America, but they now have the genetic proof that the animals are more closely tied to the camels inhabiting Asia and Arabia.
Zazula says scientists can now begin to understand why the camels went extinct 13,000 years ago, at the end of the ice age.

King Abdul Aziz City for Science and Technology unveils self-guided Black Shark boat at 38th GITEX Technology Week

  • These trucks are equipped with electronic pairing technologies, which effectively improve the shipping and distributing of goods, reduce human error

JEDDAH: King Abdul Aziz City for Science and Technology (KACST) has unveiled its Black Shark self-guided boat at the 38th GITEX Technology Week in Dubai. The vessel, which can carry out coastal surveillance and many other tasks, was developed in collaboration with Taqnia for Robotics and Smart Systems.
The development of the craft is part of a KACST initiative to localize and transform transport technology and logistics, to help achieve the aims of Vision of 2030.
The boat includes sensor systems that allow it to monitor and create a 3D map of a 200-meter area surrounding the boat, and automated control technology that gives it the ability to navigate independently and avoid collisions without human input. It can also be equipped with a flexible range of weapons, acting as a firearms platform that uses gyroscopic self-balancing technology. It has the ability to survey beaches at a range of 15 kilometers, in addition to accurately identifying its precise location with a margin of error of less than 20 centimeters using differential GPS, as well as specifying, monitoring and tracking targets.
The Black Shark also has long-range radar that covers up to 150 kilometers, and a telecommunication system to track its location, monitor its status and connect to multiple domains through command centers that allow wireless communication and remote control. It is fitted with a digital camera powered by electro-optic and infrared technology that can produce HD-quality video, and also has night vision capability.
As part of its initiative to develop transport technology and logistics, KACST has also worked on automated control technology, included self-driving heavy-duty trucks, with the University of California, Berkeley. These trucks are equipped with electronic pairing technologies, which effectively improve the shipping and distributing of goods, reduce human error, preserve resources, and reduce harmful emissions and fuel consumption.
The same technology can also, for example, transform a four-wheel-drive vehicle into a remote-controlled vehicle equipped with video cameras, infrared technology, a microphone and a control device wirelessly connected to a command center, where an operator can guide it using images from the video cameras.
