WeFuel is just the latest in a growing batch of startups that will bring fuel directly to your car, saving you the admittedly minor hassle of bringing your car to the gas station. Last year my Verge colleague Ben Popper wrote about Filld, another Silicon Valley startup that will fill up your tank for a $7 surcharge. There is also GasNinjas, FuelMe, and Yoshi, to name a few others. Most have similar fee structures, and are also starting out hyper local.
The requirement would expand on an executive order Mr. Obama issued nearly two years ago that called for federal contractors to submit salary information for women and men. Ms. Yang said the rules would be completed in September, with the first reports due a year later.
The prevailing idea about the development of a cancer is that genes randomly mutate in a healthy cell, perhaps from sun exposure, perhaps from simple bad luck. The mutated genes drive aberrant cell growth, and the growing mass of cells accumulates more and more mutations that drive it to grow faster and spread until, finally, a cancer is formed.
For their first generation of sweat-scanning wearables, Javey and colleagues set up an array of off-the-shelf sensors that track sodium, potassium, glucose, lactate, and temperature. Monitoring electrolytes such as sodium and potassium may help track conditions like dehydration, Javey said. Lactate levels may be useful for tracking muscle fatigue, and glucose may help monitor blood sugar levels.
The governor said he has been working with Argentine senator Guillermo Pereyra (who also runs the Union of Private Oil and Gas Workers in the provinces of La Pampa, Neuquen and Rio Negro) on a plan to raise prices for conventional natgas, to $5.80 per MMBtu. With the draft measure having recently been delivered to national Energy Minister Juan Jose Aranguren.
Hastings couple making switch to solar power (Michael W.)
Working at full capacity, the solar panels are anticipated to generate up to 5 kilowatts of electricity an hour. The Smiths anticipate the panels ideally will replace 80 to 90 percent of their energy consumption at home.
How to Build an Electronic Bee Counter (richcabot)
A solution suggested itself when the two of us—a field applications engineer for Analog Devices and an amateur bee enthusiast—were working together on a previous project that involved capacitive sensing. Teachman (the bee enthusiast) commented to Perrault (the applications engineer) that the sensitivity of the AD7746 [pdf] capacitance-to-digital conversion chip was better than he had expected, and wondered, “Do you think we could measure bees with this?” All else being equal, the capacitance between two electrodes depends on the dielectric constant of the substance between them. Air has a dielectric constant of roughly 1, while water comes in at around 80. As living cells are mostly water, a bee should have a detectable dielectric signature. Intrigued by the idea, we developed a custom sensor setup to measure just that.
The researchers set out to test complex sound recognition in a species of songbird, the European Starling. They trained starlings to recognize short sequences of four notes. Each of the four notes was played by a different musical instrument, meaning that each note had a different timbre, or sound quality. The sequence of notes either ascended from a low note to a high note or descended from high to low.
