Mice with half-human brains four times smarter than their peers: scientists

Published

on

According to a paper published in the latest Journal of Neuroscience, scientists have successfully injected human glial cells — which support the communication between neurons — into mouse brains, creating hybrid mice four times smarter than their peers.

Steve Goldman and his team extracted glial cells from donated fetuses and injected them into mice. Within a year, the mouse glial cells had been significantly displaced by the human.

Glial cells — in this case, astrocytes — strengthen the synapses. The average human astrocyte is 10 to 20 times larger and has 100 times as many tendrils as a mouse astrocyte.

“We could see the human cells taking over the whole space,” Goldman told New Scientist. “It seemed like the mouse counterparts were fleeing to the margins.” The human cells only stopped when they reached the physical limit of the mouse’s cranial capacity.

In memory tests, the mice with humanized brains did four times better than their peers. “These are whopping effects,” Goldman said. “We can say they were statistically and significantly smarter than control mice.”

However, he noted, “it’s still a mouse brain, not a human brain,” because all the neurons are still mouse neurons.

“But all the non-neuronal cells are human. This does not provide the animals with additional capabilities that could in any way be ascribed or perceived as specifically human,” Goldman continued. “Rather, the human cells are simply improving the efficiency of the mouse’s own neural networks. It’s still a mouse.”

The team opted not to inject the cells into humanity’s closer relatives, like chimpanzees.

“We briefly considered it but decided not to because of all the potential ethical issues,” Goldman said.

Trump spoke with Giuliani on unsecured phones that were vulnerable to Russian surveillance: report

Published

On Thursday, the Washington Post reported that President Donald Trump has communicated with his lawyer Rudy Giuliani via unsecured and unencrypted phone lines that are potentially vulnerable to interception and monitoring by Russian intelligence officials and other hostile foreign powers.

"Trump is not identified by name in the House phone records, but investigators said they suspect he may be a person with a blocked number listed as '-1' in the files," stated the report. "And administration officials said separately that Trump has communicated regularly with Giuliani on unsecured lines."

Internet debates ‘the dumbest thing Brian Kilmeade has ever said’

Published

Fox News personality Brian Kilmeade has received a great deal of attention -- and criticism -- during the Trump era.

Kilmeade co-hosts one of the President's favorite shows, "Fox and Friends," with Steve Doocy and Ainsley Earhardt on weekday mornings. He also a show on the Fox News Radio network and frequently appears on "The Five."

The former Ultimate Fighting Championship play-by-play sportscaster has also been harshly criticized for the type of comments that make the show a favorite for the president.

Journalist Molly Jong-Fast, who was widely praised her interview of Lisa Page, decided to explore Kilmeade's comments.

Trump was ‘in denial’ he would be impeached — until he watched TV yesterday: CNN reporter

Published

on

On Thursday's edition of CNN's "Anderson Cooper 360," White House correspondent Boris Sanchez said that President Donald Trump believed for weeks that Democrats were not really going to go through with impeachment — but after watching the House Judiciary Committee testimony on Wednesday, he finally realized they were serious.

"Is it clear how the president is handling this behind closed doors?" asked Cooper.

"Well, for weeks we've been hearing that the president has sort of been in denial about all of this, that he did not actually believe that Democrats in the house would vote to impeach him," said Sanchez. "We're actually told that he's come to terms with that reality in part because he was watching testimony yesterday as he was returning from a NATO leaders meeting in London."
