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.


Are robots ever going to replace doctors? Experts say ‘no’

Are robots ever going to replace doctors? Experts say ‘no’

  • The panel addressed the role of artificial intelligence (AI) and robotics in the medical field

DUBAI: The growing use of technology in the healthcare industry will continue to expand but should not take over from the primary care provided  by doctors and nurses, a panel of health experts said in a panel discussion at the World Economic Forum on Thursday.

The panel addressed the role of artificial intelligence (AI) and robotics in the medical field, agreeing that all care should remain focused on the needs of the patient, adding that “robots can’t replace doctors.”

But Leif Johansson, chairman of the board at pharmaceutical company, AstraZeneca AB, said the technology would be especially essential to “screening programs and extending access to care.”

“The only way to support primary care centers with low-skilled people, for screening purposes, will be with AI, robotics,” he explained, citing India as an example of a country with a shortage of qualified doctors who can address the needs of a massive population.

While technology presents potential benefits to the industry, Lisa Sanders, Associate Professor at the Yale Medical School, said she was concerned current technology faced a “barrier in data input.”

“How is AI or the robot going to get the data they need from patients?” Sanders, the doctor who was the inspiration behind the hit US TV show “House,” said, questioning how technology “would be able to assess patients when they’re complex and confused.”

Jodi Halpern, a professor of bioethics, shared the same sentiment, and highlighted what she described as three important situations when “a relationship with an actual human doctor makes a difference for effective healthcare.”

One was taking medical history from patients, Halpern said, explaining most patients would only disclose personal information when there’s empathy from doctors.

“If we don't get a good history, we won't get a good treatment," she added.

Another was ensuring patients take medication, and lastly was helping people deal with bad news.

Sanders, a physician herself, said “it’s not the thinking” that doctors need help from technology for, but "other things like dealing with poorly conceived systems of medical records."
