According to a new study published in the journal Science Advances, researchers from Australia and France have shown that bees can perform simple arithmetic, adding and subtracting small numbers by studying color-coded shapes. CNET reports: To test the buzzers' ability to perform arithmetic, the team used a three-chambered maze shaped like a Y, training bees to enter through a hole into a small chamber where they would see their first stimulus: blue or yellow shapes on a plain, grey background. The number of shapes varied between 1 and 5 and the color of the shapes told the bee whether it needed to add one (blue) or subtract one (yellow) from the initial number. The bee then flew into a subsequent chamber which presented both a correct option and an incorrect option. To train the bees, the correct option rewarded the critters with a drop of tasty sugar solution -- a delightful dessert for the bee. On the other hand, selecting the incorrect solution resulted in a nasty drop of quinine -- like a slab of Brussels sprouts slathered in chocolate.

The testing procedure itself focused on 14 bees undergoing four tests of 10 choices. The tests themselves were "non-reinforced," so they didn't receive reward or punishment when selecting their "answers" during testing. Because the bees were subjected to two answers each time, the expectation is that -- purely by chance -- they would select the correct answer 50 percent of the time. But the bees performed significantly better than chance would predict, selecting the correct answer around 65 percent of the time.

According to Elon Musk, the dual-motor Tesla Model 3 is expected to be released in July. "Musk linked the release of the new Model 3 powertrain with the automaker achieving a production rate of 5,000 Model 3 vehicles per week," reports Electrek. From the report: Earlier this year, we reported on Tesla registering 19 Model 3 VINs with dual motor powertrain with NHTSA in the latest batch of new VINs. It happened right after the Tesla Model 3 dual motor powertrain design leaked in the latest design studio update. Then in February, Tesla registered a new batch of Model 3 VINs, including two dozen Model 3 VINs with the dual motor powertrain. It raised Model 3 reservation holders' hope that the new configuration could soon become available, but now Musk confirmed that it is still a few months away in a series of tweets last night. The CEO also linked the timing with the release of the Model 3 white interior. Tesla currently only offers a single interior option with black upholstery. The dual motor Model 3 is expected to deliver a slightly longer range and offer a quicker acceleration than the current single motor rear-wheel-drive version.

Android 5.0 Lollipop and its successor 5.1 have seen very low adoption rates — 9.0% and 0.7% respectively. Almost 40% of users are still on KitKat. 6% lag far behind on Gingerbread and Froyo. The article points out that even Microsoft is now making efforts to both streamline Windows upgrades and adapt Android (and iOS) apps to run on Windows.

If Google doesn't adapt, "it risks having users (slowly but surely) switch to more secure platforms that do give them updates in a timely manner. And if users want those platforms, OEMs will have no choice but to switch to them too, leaving Google with less and less Android adoption." The author also says OEMs and carriers can no longer be trusted to handle operating system updates, because they've proven themselves quite incapable of doing so in a reasonable manner.

ral writes "The human tongue can taste more than sweet, sour, salty, bitter and protein. Researchers have added fat to that list. Dr. Russell Keast, an exercise and nutrition sciences professor at Deakin University in Melbourne, told Slashfood, 'This makes logical sense. We have sweet to identify carbohydrate/sugars, and umami to identify protein/amino acids, so we could expect a taste to identify the other macronutrient: fat.' In the Deakin study, which appears in the latest issue of the British Journal of Nutrition, Dr. Keast and his team gave a group of 33 people fatty acids found in common foods, mixed in with nonfat milk to disguise the telltale fat texture. All 33 could detect the fatty acids to at least a small degree."

52-year-old Anthony Digati was arrested for trying to extort $200,000 from an insurance firm by threatening to spam them with six million emails unless they paid up. Digati said he would use a spam service and his amazing talents as a "huge social networker" to drag the company "through the muddiest waters imaginable" and presumably unfriend everyone. He added that the price would increase to $3 million if they failed to pay up by Monday, according to federal authorities.

An anonymous reader passes along this quote from a report at 24/7 Wall St.: "There have been over 3 billion downloads since the inception of the App Store. Assuming the proportion of those that are paid apps falls in the middle of the Bernstein estimate, 17% or 510 million of these were paid applications. Based on our review of current information, paid applications have a piracy rate of around 75%. That supports the figure that for every paid download, there have been 3 pirated downloads. That puts the number of pirate downloads at 1.53 billion. If the average price of a paid application is $3, that is $4.59 billion dollars in losses split between Apple and the application developers. That is, of course, assuming that all of those pirates would have made purchases had the application not been available to them for free. This is almost certainly not the case. A fair estimate of the proportion of people who would have used the App Store if they did not use pirated applications is about 10%. This estimate yields about $459 million in lost revenue for Apple and application developers." A response posted at Mashable takes issue with some of the figures, particularly the 75% piracy rate. While such rates have been seen with game apps, it's unclear whether non-game apps suffer the same fate.
