KANSAS CITY, Mo. – After more than a century embedded beneath the paint, researchers discovered a grasshopper beneath the brushstrokes in a Vincent Van Gogh painting at the Nelson Atkins Art Museum.Paintings Conservator Mary Schafer discovered the tiny grasshopper in the lower foreground of the landscape while working under a microscope. It is not easily seen by the naked eye.Photo courtesy of the Nelson-Atkins. According to a news release from the Nelson, Schafer and other researchers hoped the grasshopper could be used to determine a more specific date on the painting.“It is not unusual to find insects or plant material in a painting that was completed outdoors,” Schafer said. “But in this case, we were curious if the grasshopper could be used to identify the particular season in which this work was painted.”Unfortunately, entomologists were unable to date the painting, but could determine the grasshopper had died before landing on Van Gogh’s canvas.Additional research on Van Gogh’s “Olive Trees” is underway. The painting is available for viewing at the Nelson Atkins Museum of Art in Kansas City, Missouri.  1144

JACKSON, Miss. (AP) — Charles Evers, the older brother of slain civil rights leader Medgar Evers and a longtime figure in Mississippi politics, has died in Mississippi. He was 97. A coroner says Evers died of "natural causes" Wednesday in Brandon. Medgar Evers was a Mississippi NAACP leader who was assassinated outside his Jackson home in 1963. Charles Evers in 1969 became the first Black candidate since Reconstruction to win a mayor's race in any multiracial town in Mississippi. He ran unsuccessfully for governor in 1971 and for U.S. Senate in 1978, both times as an independent. He was later a Republican but publicly supported Barack Obama for president. 671

Joy Reid opened her show on MSNBC Saturday with a mea culpa about past homophobic remarks and admitted cybersecurity experts haven't been able to prove her former blog was hacked.Reid reiterated claims that she was not the author of homophobic posts that were recently surfaced from a blog she ran in the 2000s. But she acknowledged making past comments that have been described as homophobic."Many of you have seen these blog posts circulating online and on social media. Many of them are homophobic, discriminatory and outright weird and hateful," she said at the open of her weekend show, "AM Joy.""I spent a lot of time trying to make sense of these posts. I hired cybersecurity experts to see if somebody had manipulated my words or my former blog, and the reality is they have not been able to prove it."She added: "I genuinely do not believe I wrote those hateful things because they are completely alien to me. But I can definitely understand based on things I have tweeted and have written in the past why some people don't believe me." 1053

LA JOLLA, Calif. (KGTV) - A researcher at UC San Diego just got a million grant to further his work into nanosponge therapy.Liangfang Zhang, a professor of nanoengineering and bioengineering, has been working on creating macrophage cellular nanosponges, tiny particles covered in white blood cell membranes, to treat sepsis and other diseases."They can be used to bind to the virus and neutralize the virus," Zhang says. "So now the virus would lose the ability to infect the host cells."The nanosponges act as decoys, tricking a disease or virus into binding with them instead of with human cells. While the initial aim is to treat sepsis, Zhang says it has applications to other deadly diseases, including COVID-19."The formulation that we're developing for treatment of Sepsis is the same formulation that you will use with COVID-19," he says.The grant comes from CARB-X, a Boston-based medical philanthropy that specializes in funding research into antibacterial treatments. Zhang says the money will be used for his company, Cellics Therapeutics, to further advance the research into clinical trials, FDA approval, and production of the nanosponge therapy.Steve Chen, president and chief medical officer of Cellics Therapeutics, says he's hopeful they can advance the nanosponges into human trials within two years."We're essentially looking at how this platform can treat not just infectious disease or future pandemics, but you could actually have a lot of applications in any type of autoimmune diseases or any type of inflammatory diseases," says Chen.In an early study published this year, Zhang's research showed the nanosponges were around 90% effective at blocking infections from taking hold.RELATED: UC San Diego researchers testing nanosponges to fight COVID-19Chen says the research and trial period may take too long for the nanosponges to be used during the current coronavirus pandemic. But he's hopeful it will help make the next outbreak less severe."My sincere desire is that we are not going to need this for COVID-19. But I think this does position us very well for any potential future kind of viral outbreak," says Chen.Cellics is also working on a Red Blood Cell version of their nanosponges, which may be ready for human trials within a year. 2283
