Medical imaging struggles to read dark skin. Researchers say they’ve found a way to make it easier

CNN  —  Traditional medical imaging – used to diagnose, monitor or treat certain medical conditions – has long struggled to get clear pictures of patients with dark skin, according to experts. Researchers say they have found a way to improve medical imaging, a process through which physicians can observe the inside of the body, regardless of skin tone. The new findings were published in the October edition of the journal Photoacoustics. The team tested the forearms of 18 volunteers, with skin tones ranging from light to dark. They found that a distortion of the photoacoustic signal that makes the imaging more difficult to read, called clutter, increased with darkness of skin. “When you h...

‘Oppenheimer’ fanfare likely to fuel record attendance at New Mexico’s Trinity atomic bomb test site

WHITE SANDS MISSILE RANGE, N.M. -- Thousands of visitors are expected to descend Saturday on the southern New Mexico site where the world's first atomic bomb was detonated, with officials preparing for a record turnout amid ongoing fanfare surrounding Christopher Nolan's blockbuster film, “ Oppenheimer.”Trinity Site, a designated National Historic Landmark, is usually closed to the public because of its proximity to the impact zone for missiles fired at White Sands Missile Range. But twice a year, in April and October, the site opens to spectators. This may be the first time gaining entry will be like getting a golden ticket to Willy Wonka's chocolate factory. White Sands officials warned online that the wait to enter the gates could be as long as two hours. No more than 5,000 visitors ar...

Katalin Karikó’s Nobel Prize Marks the Beginning of a Vaccine Revolution

No one expected the first Covid-19 vaccine to be as good as it was. “We were hoping for around 70 percent, that’s a success,” says Dr Ann Falsey, a professor of medicine at the University of Rochester, New York, who ran a 150-person trial site for the Pfizer-BioNTech vaccine in 2020.Even Uğur Şahin, the co-founder and CEO of BioNTech, who had shepherded the drug from its earliest stages, had some doubts. All the preliminary laboratory tests looked good; having seen them, he would routinely tell people that “immunologically, this is a near-perfect vaccine.” But that doesn’t always mean it will work against “the beast, the thing out there” in the real world. It wasn’t until November 9, 2020, three months into the final clinical trial, that he finally got the good news. “More than 90 percent...

What Insects Go Through Is Even Weirder Than We Thought

“For me, it was a road-to-Damascus type of moment,” James Truman, an entomologist, told me, recalling an encounter when he was sixteen. “My family had a summer place, a trailer, on the shores of Lake Erie. I was walking through the trailer park when I looked up and I saw an insect up in a tree. It was a parasitic wasp, with an abdomen three inches long.” He thought, What the heck is that? That curiosity “caused me to get a book,” Truman said. It was “Field Book of Insects,” by Frank E. Lutz, first published in 1918, with detailed drawings by the scientific illustrator Edna Libby Beutenmüller. “I had always known I wanted to be a biologist, but I had flipped from one interest to another: birds, mammals, whatever,” Truman said. Then he was transformed. He knew he would study insects.Insects...
