Technology and its discontents
Nuclear bombs can destroy us. Facebook undermines our privacy. Artificial intelligence (AI) and robots can enslave us (or, worse, take our jobs). Synthetic biology and geneediting have humans playing God. Social media make us depressed: we’ve never been so connected yet never so alone.
Those are just a few of the complaints leveled against technology. For most of human history, however, technology was mostly seen as a force for good. More people would live because of technical progress, from refrigeration to vaccination, than perish because of it, despite lethal inventions such as gunpowder.

A new study, published Monday in the journal Nature Astronomy, established the chemical composition of Uranus’ upper cloud deck for the first time. Using an instrument called the Near-Infrared Integral Field Spectrometer (NIFS) at the Gemini North telescope in Hawaii, researchers determined that Uranus’ cloud cover is composed of hydrogen sulfide (H2S) gas, which is what gives rotten eggs their distinctive, noxious scent.

New Studies Link Cell Phone Radiation with Cancer Researchers call for greater caution, but skeptics say the evidence from rat studies is not convincing By Charles Schmidt

    Does cell phone radiation cause cancer? New studies show a correlation in lab rats, but the evidence may not resolve ongoing debates over causality or whether any effects arise in people.
    The ionizing radiation given off by sources such as x-ray machines and the sun boosts cancer risk by shredding molecules in the body. But the nonionizing radio-frequency (RF) radiation that cell phones and other wireless devices emit has just one known biological effect: an ability to heat tissue by exciting its molecules. Still, evidence advanced by the studies shows prolonged exposure to even very low levels of RF radiation, perhaps by mechanisms other than heating that remain unknown, makes rats uniquely prone to a rare tumor called a schwannoma, which affects a type of neuron (or nerve cell) called a Schwann cell.

Do Gun Owners Want Gun Control?

By Jess Bidgood and Sabrina Tavernise

Tom Galinat signed a letter to lawmakers, urging them to expand background checks for gun purchases. Mr. Galinat, 35, a farmer and hunter who owns nine guns, traveled last month from his home in Peacham, Vt., to Montpelier, the state capital, with a firm goal in mind: Convince lawmakers to enact a ban on high-capacity magazines.

Jonathan Leach, 56, a policy analyst in Augusta, Me., and the owner of about 10 guns, testified before Maine legislators in favor of a bill to let judges order people deemed dangerous to surrender their firearms. Mr. Leach said he wanted to serve as a counterweight to gun rights enthusiasts he knew would speak against the idea.
