writes: Ever wonder while standing at a urinal what is the best target to minimize or maximize splashing? Ever wonder where the big puddles on the floor come from? Well wonder no longer; science once more comes to the rescue.
Fluid dynamics researchers at Brigham Young University have determined the optimum distance and angle for minimal splashing. (Hint: don't aim at the urinal cake)Link to Original Source
writes: The Environment Protection Agency has lowered the amount of fine-particle matter per cubic meter that new wood stoves are allowed to release into the atmosphere by 20%. Most wood stoves in use today are of the type that is now illegal to manufacture or sell, and old stoves traded in for credit towards new ones must be scrapped out. This shouldn't be much of a surprise since more and more local governments are banning wood-burning stoves and fireplaces entirely, citing smog and air pollution concerns.

Google then connects these store visits to Google searches conducted on smartphones. If someone conducts a Google mobile search for “screwdrivers,” for instance, a local hardware store could bid to have its store listing served to that user. By pairing that person’s location data with its database of store listings, Google can see if the person who saw that ad subsequently visited the store.It is easiest for Google to conduct this passive location tracking on Android users, since Google has embedded location tracking into the software. Once Android users opt in to location services, Google starts collecting their location data as continuously as technologically possible.

writes: Matthew Philips writes at Bloomberg that US Secretary of State John Kerry landed in Geneva on Friday to begin negotiations with Iran over its nuclear weapons program and there is sudden optimism that a deal is in the offing. But the simple fact is that Iran would not be coming to the negotiating table without the US oil boom. Over the last two years, the US has increased its crude production by about 2 million barrels a day. According to a recent report from the Congressional Research Service (pdf), Iran’s oil exports have been cut in half since 2011 (PDF), from 2.5 million barrels per day to a bit more than 1 million today. As a result, Iran has had to halt an equal amount of production. “I think it’s pretty clear that without the U.S. shale revolution, it never would have been possible to put this kind of embargo on Iran,” says Julius Walker. “Without US production gains, I think we’d be looking at $150 a barrel." Instead, international prices have hovered around $110, and are less than $100 in the US. According to data from Bloomberg, the combined carrying capacity of oil tankers leaving Iranian ports last month dropped 22 percent from September. “They’re having a very hard time finding buyers,” says Walker. If a deal gets done, the trick will be to ease Iranian oil back onto the broader market without disrupting prices. If not managed properly, flooding the market with Iranian crude could carry its own negative consequences by suddenly making fracked oil in the US unprofitable.Link to Original Source
writes: A US company that has developed an "electronic backpack" that fits onto a cockroach allowing its movements to be controlled by a mobile phone app has defended itself against cruelty claims.
For the "electronic backpack" to work the cockroaches have to be placed in icy water to subdue them before sandpaper is used to remove the waxy coating on the shell of the insect's head.
An electrode connector and electrodes are then glued on to the insect's body and a needle is used to poke a hole in their thorax in order to insert a wire. Their antennae are then cut and electrodes are inserted. A circuit is attached to their backs, and signals are received through a mobile phone app allowing users to control the cockroaches' movements to the left and to the right.
The Roboroach weighs 4.5g and is compatible with most mobile phones. It overrides the insect's antennae making it turn left and right at the flick of a switch.Link to Original Source
