3D-printed pinhead battery could power robots

We’ve seen some very sophisticated 3D-printed objects recently, but never a tiny 3D-printed battery — one that’s as small as a grain of sand, no less.

A group of U.S. and Korean researchers has managed to print a lithium-ion microbattery that can fit on the head of a pin.

Although it weighs less than 100 micrograms, it can store as much power per gram as larger Li-ion batteries used in laptops or electric vehicles. It could even power tiny robots or medical devices.

In a paper published in Advanced Materials, Harvard University’s Jennifer Lewis and colleagues describe printing a “3D interdigitated microbattery architecture” with concentrated lithium oxide-based inks.

Vine for Android adds Facebook sharing, searches for hashtags and users

Vine on Android

Twitter isn’t about to let Video on Instagram go completely unanswered — it just posted an update to Vine for Android that could offer a few reasons to stay with the earlier service. Short-form movie makers on Android now have more of the features we’ve seen on iOS, including Facebook sharing as well as searches for hashtags and users. The release also smooths out the rough experience that has characterized the Android experience since launch, boosting both capture speeds and the final video quality. The app may still fall short of the newer Instagram release in a few areas, but those who prefer Vine’s approach can grab its refresh at Google Play.

Mark Begich: New York Fundraiser Cancellation Had Nothing To Do With Bloomberg

SAN JOSE, Calif. — Sen. Mark Begich (D-Alaska) shrugged off the influence of New York Mayor Michael Bloomberg (I) and his gun control group on Friday, saying Bloomberg had nothing to do with the cancellation of a fundraiser for the senator earlier this week.

Begich was set to hold a fundraiser in New York on Monday, hosted by financial industry titans Peter Solomon and Robert Rubin. But this week, Politico reported that the event had been canceled, just a few days after Bloomberg sent a letter to New York donors asking them to withhold contributions to senators who voted against bipartisan gun background check legislation.

Begich and three other Democratic senators joined with the majority of Republicans and opposed the bill in April, dooming it to failure.

MINNEAPOLIS — A Minnesota man on furlough from prison removed an ankle bracelet that monitored his whereabouts, returned to the home of his prior burglary victim and raped her, authorities said Friday.

Curtez Deshawn Graham, 18, of St. Paul, told police he wanted to scare the 65-year-old woman and send her a message because he was mad that she sent him away for 14 months, according to the criminal complaint. Graham is charged with eight counts, including criminal sexual conduct.

Paula Deen Defended Southern Attitude Towards Race In Fall 2012 (VIDEO)

On Friday afternoon, the Food Network announced that it was dropping Paula Deen from its network after 14 years on air, after the National Enquirer reported (and The Huffington Post confirmed) that the chef had aired a series of arguably racist comments while being deposed for a lawsuit. But the deposition wasn’t the first time that Paula Deen has voiced questionable views on race.

Last fall, I visited the New York Times headquarters to see Paula Deen talk with Times reporter Kim Severson on a variety of topics. When I wrote it up, I focused mostly on her comments about her diabetes, because Deen’s endorsement of the diabetes drug Victoza was still hot news. But I also briefly mentioned a strange segment of the talk in which she talked about Southern attitudes toward race. Today, all this talk of her recent racist comments spurred me to revisit the video of the TimesTalk. It’s really shocking stuff. Watch the video at the top of this entry for our race-related highlights.

Severson first broaches the topic of race relations after showing a clip from Deen’s appearance on “Who Do You Think You Are,” in which she visits a large plantation a distant ancestor of hers named Billy had owned. (Along with 30 slaves.) That prompts Deen to talk about the Civil War and the Antebellum South.
