Measles Cases in 2019 Have Hit a 25-Year High Amid Ongoing Outbreaks, CDC Says

The Centers for Disease Control and Prevention on Thursday said that measles cases hit a higher number this year than has been reported since 1994. If the outbreaks continue as they are, the health agency says it could cost the U.S. its elimination status.

Scientists Identify Factors That Make People Naturally Resistant to H.I.V.

Developing an H.I.V. vaccine has been a perplexing challenge that has mostly resulted in failure, but now scientists have identified key factors that allow some people to naturally suppress the H.I.V. virus—work that could lead to better vaccines to both treat and prevent the infection. Researchers believe they have identified crucial points on the virus’s surface where the immune system can successfully attack H.I.V.

CRISPR is now being used on humans in the U.S.

The first U.S. trial of CRISPR in humans has begun, NPR reported Tuesday. Two patients are currently being treated as part of a University of Pennsylvania study. Per NPR, both have difficult-to-treat forms of cancer and both have relapsed after regular treatments. As part of the trial, researchers are taking immune cells from the patients’ own bodies and editing them with CRISPR before putting them back in. The hope is that these edited cells will be better at identifying and attacking the cancer than their unaltered counterparts. According to the U.S. government clinical trial registry, the researchers are hoping to enroll 18 people in their study. But it’s not certain yet whether they’ll be approved for that many subjects, reports Jon Fingas for Engadget. Continue reading CRISPR is now being used on humans in the U.S.

A Scottish Woman Doesn’t Feel Pain or Stress. Now Researchers Think They Know Why

When she was eight years old, Jo Cameron broke her arm and didn’t tell anyone for days; it just wasn’t bothering her. In the six-odd decades since, she has sustained numerous injuries and felt barely any pain. Sometimes, she accidentally leans on her stove, only to notice when she smells burning flesh.

Mosquitoes Can Smell Your Sweat

When a mosquito lands and your arm and starts taking a drink, it’s not just an unhappy accident. Mosquitoes use an array of chemical neuroreceptors to track down their next blood meal. Now, researchers have identified a key receptor that detects the lactic acid in human sweat, a finding that could eventually help people avoid becoming fast food for the insects.
