Post a comment Researchers at the University of Minnesota have figured out how to open a window into the brains of mice by using a transparent skull implant. It’s called the See-Shell. “What we are trying to do is to see if we can visualize and interact with large parts of the mouse brain surface, called the cortex, over long periods of time,” says mechanical engineering professor Suhasa Kodandaramaiah, co-author of a study on the See-Shell that appeared in the journal Nature Communications on Tuesday. A spider’s erection, and other cool things trapped in amber A video released by the university shows a sped-up mouse brain scan as seen through the See-Shell. “Changes in brightness correspond to waxing and waning of neural activity. Subtle flashes are periods when the whole brain suddenly becomes active,” the school notes.The researchers digitally scan a mouse’s skull and use the data to create a matching transparent piece using a 3D printer. The skull is then surgically replaced with the See-Shell. The mouse studied by the team did not reject the implant, which allowed them to monitor its brain over several months. The researchers intend to make the See-Shell commercially available to other researchers. 20 Photos Sci-Tech Tags 0
Emily Albracht, Rachel Zein for The Texas TribuneMost Texas voters oppose separating children and parents apprehended while trying to enter the country illegally, but there are gaping partisan and gender differences in the electorate, according to the latest University of Texas/Texas Tribune Poll.Generally speaking, men are more likely than women to say they support “separating children and parents who are apprehended while trying to enter the U.S. illegally,” and Republicans are more likely than Democrats to support the practice.Overall, 28 percent of Texas voters support the practice — 16 percent strongly so — while 57 percent oppose it — 44 percent strongly so.The partisan gap was striking. While 83 percent of Democratic voters oppose separation of parents and children at the border, only 46 percent of independents and 35 percent of Republicans were opposed. A plurality of Republicans — 46 percent — said they support the practice; among independents and Democrats, opponents outnumbered supporters.Tea Party Republicans favor the practice 55 percent to 30 percent; non-Tea Party Republicans favor it by a smaller margin of 45 percent to 38 percent.Overall, 64 percent of women voters oppose the separation practice, and 50 percent of the men agree with them. Among Democrats, there’s some accord, with 86 percent of women and 78 percent of men opposing family separations.On the Republican side, however, the differences are stark — and help explain why so many Republican politicians have shifted their positions since the separations became widely known. While 56 percent of Republican men favor splitting parents and children at illegal entry points on the border and 30 percent oppose it, a plurality of Republican women are against the practice: 37 percent favor it and 42 percent oppose it.On Wednesday, President Donald Trump signed an executive order halting the separations, sticking with his position on strong borders while saying families will be kept together.“The numbers are pretty lopsided,” said Daron Shaw, co-director of the poll and a government professor at the University of Texas at Austin. “President Trump must’ve been looking at similar numbers. Someone pointed out that ‘You don’t have to be Ronald Reagan to see the power of those pictures.’ I think Trump understands that this is a political loser.”The poll closed on Sunday night, before the president decided to revoke the policy and before many Texas Republican officeholders came out against the practice. Democratic politicians were getting a very clear signal, but for Republicans, it took some time to figure out what voters wanted, said Jim Henson, who co-directs the poll and runs the Texas Politics Project at UT-Austin. “It’s hard to take elite cues if you’re a Republican because there are so many viewpoints.”Some Republican voters might have misgivings about family separations, but their concern about the Texas-Mexico border hasn’t wavered.Border security and immigration continue to top Texas voters’ list of the most important problems facing the state. That’s driven by Republican voters, more than half of whom listed either immigration or border security as their top concern. Tea Party Republicans were most likely to choose those two items; 59 percent of them did so. Moral decline was a distant third on GOP voters’ list, with 6 percent listing that as the top problem facing the state. Less than 10 percent of Democrats listed those two items. Their top concerns were political corruption/leadership (16 percent), gun control/gun violence (11 percent), health care (11 percent) and education (10 percent).Political corruption/leadership, immigration and moral decline topped voters’ concerns about the country. Democrats put political corruption/leadership at the top of their list (23 percent), while the Republican list was capped by immigration and moral decline, each listed by 18 percent of GOP voters. Border security was third, at 10 percent; combined with immigration, it was chosen as the country’s most important problem by more than a quarter of the Republican respondents. The Democrats’ list was rounded out by gun control/gun violence (14 percent) and health care (11 percent).NAFTA and foreign involvementThe North American Free Trade Agreement is more popular with Democrats than with Republicans — a reversal from the early years of that 1990s-era pact.Overall, Texans have decidedly mixed views on NAFTA, which is currently being renegotiated by the United States, Canada and Mexico: 34 percent said they think it has been good for the state economy, 28 percent said it’s been bad, and 38 percent said either that they don’t know or have no opinion about it.A majority of Democrats — 54 percent — said NAFTA has been beneficial to Texas, while only 17 percent of Republicans said that. Only 10 percent of Democrats said it was bad for the state, while 43 percent of Republicans said so.College-educated voters were more likely to favor the trade agreement, with 46 percent calling it a good deal and 26 calling it a bad one. By comparison, 30 percent of voters who didn’t go to college called it a good deal and 64 percent called it a bad one.Asked whether they agree or disagree with a statement about foreign affairs — “This country would be better off if we just stayed home and did not concern ourselves with problems in other parts of the world” —39 percent agreed and 51 percent said they disagree. Democrats were more inclined to disagree (63 percent), while Republicans were split down the middle, 46 percent to 46 percent.The University of Texas/Texas Tribune internet survey of 1,200 registered voters was conducted from June 8 to June 17 and has an overall margin of error of +/- 2.83 percentage points. Numbers in charts might not add up to 100 percent because of rounding. Share
