"In response to threats by US President Donald Trump to somehow acquire Greenland (Kalaallit Nunaat), US scientists have drafted what they call a statement in solidarity with the island, open to any US-based researchers who have conducted research there. "A lot of people in the US - not just scientists - are very upset about the rhetoric directed towards Greenland. But scientists who work there feel it very personally," says paleoclimatologist Yarrow Axford, who is one of the creators of the initiative."
"Scientists have identified a neural circuit that seems to act as a 'motivation brake', dampening the drive to begin a difficult or unpleasant task. When the team selectively suppressed this circuit in macaque monkeys (Macaca fuscata), the animals were more willing to start a potentially unpleasant job. If confirmed in humans, the findings could shift how clinicians approach the debilitating lack of motivation associated with depression."
US scientists drafted an open statement in solidarity with Greenland after threats by US President Donald Trump to acquire the island; the statement is available to US-based researchers who have worked there. Paleoclimatologist Yarrow Axford said many people in the US are upset about rhetoric directed towards Greenland and that scientists who work there feel the rhetoric personally, expressing support for colleagues and friends on the island. Neuroscientists identified a neural circuit acting as a 'motivation brake' that dampens the drive to start difficult or unpleasant tasks; suppressing it in macaque monkeys increased willingness to begin such jobs. If the circuit functions similarly in humans, the finding could change clinical approaches to the lack of motivation seen in depression, but easing the brake could risk inadvertent overwork and burnout. The US Congress also published a spending bill that effectively axes NASA's Mars Sample Return programme.
