12:13 PM | Roundup: Mars meteors, robotic gardeners, a tight squeeze for molecules, and atom bomb history
Here’s a little bit of everything (almost) going on in Iowa science, from the interplanetary to the tiny and from the latest in robotics to the history of Iowa’s role in the atom bomb. University of Iowa researchers last week released results from a probe that tracked the impact of a comet flyby on Mars’ […]

10:30 PM | U.N. General Assembly Votes Overwhelmingly In Favor of Ending U.S. Embargo On Cuba
For the 23rd straight year, the United Nations General Assembly has once again voted to condemn the American embargo on Cuba. Out of the 193 member countries, 188 voted in favor of the “Necessity of Ending the Economic, Commercial and Financial Embargo imposed by the United States of America against Cuba” resolution. Only two countries, the U.S. and Israel, voted against the resolution (Palau, Micronesia and the Marshall Islands abstained from the vote).

7:43 PM | President Obama Speaks Out, Endorsing “Strongest Possible Rules” to Protect Net Neutrality
Net neutrality has been a major issue of discussion in the United States since the FCC (Federal Communications Commission) voted back in May to move forward on a plan that would create “internet fast lanes”, allowing larger companies to pay more for faster speeds on their sites. The American public has shown strong opposition to this idea, and while FCC Chairman Tom Wheeler has expressed his support for the fast lanes, the people now have a very powerful ally on

5:00 PM | What Zebrafish Teach Us About Touch
Unlike the sense of vision, which is perceived only by light-sensitive photoreceptors in our eyes, the mechanoreceptors that respond to light touch are located in sensory neurons all over the body.  Our sense of touch starts in the skin, where sensory neurons with elaborate dendrites just below the skin’s surface provide dense coverage over the … Continue reading →

4:18 PM | This Google-Owned Firm Is Building Some Insane Robots, Including A Robo Karate Kid (Video)
Last December, Google raised a lot of eyebrows when they purchased the robotics firm Boston Dynamics. The acquisition led to all kinds of speculation about what Google was going to do with this new robotic wing of its business. Well, there’s at least one cool project Boston Dynamics has been working on recently: a 6ft 2in, 330-pound robot with exceptional levels of balance and maneuverability. They call it the Atlas bot. The robot is a joint project between Boston Dynamics, the

2:37 AM | Watch Live: Rosetta Spacecraft Prepares To Land Probe On Moving Comet
The Rosetta Spacecraft was launched in 2004 by the European Space Agency with aid from NASA. Rosetta’s mission has been to rendezvous with Comet 67P/Churyumov-Gerasimenko, orbit the comet, and launch and land a robot lander called Philae onto the comet. After nearly ten years in hibernation, the Rosetta Spacecraft awoke in August as it approached the comet. Upon arrival, Rosetta began orbiting Comet 67P/Churyumov-Gerasimenko, scouting for landing locations. Early […]

11:19 PM | New Global Regulations Aim to Prevent Bailouts of Banks That Are “Too Big to Fail”
During the global financial crisis of 2007-2008, governments around the world spent trillions of dollars bailing out banks that had gone belly-up as a result of overly-risky trading practices. In the United States alone, the total cost of financial bailouts has been estimated at anywhere from about $10 trillion to upwards of $29 trillion (that’s 72% more than our annual GDP). The logic behind the bailouts: allowing such large and influential institutions to go bankrupt would […]

Three International Space Station (ISS) crewmen returned safely to Earth yesterday, landing just northeast of Arkalyk, Kazakhstan. Recovery teams were standing by in the 23-degree temperature as the Russian Soyuz capsule, the same spacecraft the crew rode in to reach the space station on May 28, landed safely back on Earth. The crew included veteran Russian cosmonaut Maxim Suraev, NASA astronaut Reid Wiseman, and German flight engineer Alexander Gerst from the European Space […]
