Computer scientist, pixel inventor Russell Kirsch dead at 91

PORTLAND, Ore. (AP) ??" Russell Kirsch, a computer scientist credited with inventing the pixel and scanning the world's first digital photograph, died Aug. 11 at his home in Portland, Oregon, The Oregonian reported. He was 91.

Pixels, the digital dots used to display photos, video and more on phone and computer screens, weren't an obvious innovation in 1957, when Kirsch created a small, 2-by-2-inch black-and-white digital image of his son, Walden, as an infant. That was among the first images ever scanned into a computer, using a device created by his research team at the U.S... Read More

Tear gas at Portland protests raises concern about pollution

SALEM, Ore. (AP) ??" The presence of U.S. agents has diminished in Portland, Oregon, but city officials are still cleaning up tear gas residue from the streets, dirt and possibly the storm drains after the chemical was used frequently by both police and federal officers during more than two months of often-violent protests over racial injustice.

The Portland Bureau of Environmental Services cleaned and took samples from six storm drains last week around the federal courthouse and a building with a police station and jail that have been targeted in nightly demonstrations... Read More

Science and politics tied up in global race for a vaccine

WASHINGTON (AP) ??" No, Russia isn't having a Sputnik moment.

The announcement Tuesday by Russian President Vladimir Putin that his country was the first to approve a coronavirus vaccine did not provoke the awe and wonder of the Soviet Union's launch of the first satellite into orbit in 1957. Instead, it was met by doubts about the science and safety.

But the claim underscored how, like the space race, the competition to have the first vaccine is about international rivalries as well as science. The first nation to develop a way to defeat the novel coronavirus will... Read More

6 former EPA bosses call for agency reset after election

Six former Environmental Protection Agency chiefs are calling for an agency reset after President Donald Trump's regulation-chopping, industry-minded first term, backing a detailed plan by former EPA staffers that ranges from renouncing political influence in regulation to backing climate-friendly electric vehicles.

Most living former EPA heads joined in Wednesday's appeal, with Trump's first EPA chief, Scott Pruitt, being the notable exception. The group ??" William Reilly, Lee Thomas, Carol Browner, Christine Todd Whitman, Lisa Jackson and Gina McCarthy ??" served under... Read More

Companies test antibody drugs to treat, prevent COVID-19

With a coronavirus vaccine still months off, companies are rushing to test what may be the next best thing: drugs that deliver antibodies to fight the virus right away, without having to train the immune system to make them.

Antibodies are proteins the body makes when an infection occurs; they attach to a virus and help it be eliminated. Vaccines work by tricking the body into thinking there's an infection so it makes antibodies and remembers how to do that if the real bug turns up.

But it can take a month or two after vaccination or infection for the most effective The... Read More
