In the United States, April is a time to promote awareness about sexual assault and other forms of sexual violence. Sexual violence is a worldwide, pervasive problem that affects every one of us. By raising awareness, we can learn how to cultivate safe workplaces, homes, online platforms and other spaces, to prevent sexual violence and provide support for survivors.
In honor of Sexual Assault Awareness Month (SAAM), here are some of the key facts and figures about sexual violence gathered from the Rape, Abuse & Incest National Network (RAINN). Take a few minutes to read and learn more about this issue as SAAM draws to a close.
As a lifelong Midwesterner, I’m accustomed to the short-lived, false springs of January and February. I know to save gleeful cries of “spring is here!” until the trees bud and I can hear the buzzing trill of red-winged blackbirds and the calls of other birds returning from their winter homes. But this spring, the return of birdsong is not all good news.
In the rapidly shifting context of a pandemic, public health officials need a way to quickly assess how vaccinations perform in changing situations. One approach is to identify correlates of protection, or biological markers that correlate with a certain level of protection from disease. This tool is used to assess the design and formulation of annual influenza vaccines, as immune system markers that correlate with protection from flu can give developers a sense of how effective the vaccine might be for different population groups. Though they are not a replacement for rigorous clinical trials, correlates of protection can provide meaningful and predictive data for vaccine developers with smaller trial sizes and less time.
A study published in November 2021 indicated that levels of binding antibodies and neutralizing antibodies for the SARS-CoV-2 virus in blood serum are correlates of protection for Moderna, Inc.’s COVE phase 3 clinical trial of their mRNA COVID-19 vaccine.
Graduate students often struggle to envision careers outside of the academic world. A partnership between Promega Ibérica and the Universidad Autónoma de Madrid (UAM) is helping change that for students in UAM’s Cellular Dynamics and Biomolecules master’s degree program.
Earlier this year, I had an opportunity to attend a virtual talk presented by leading climate scientist and communicator Dr. Katharine Hayhoe. She began by asking the audience to send in one word that describes how they feel when thinking about climate change. The responses popped up live in a word cloud on Hayhoe’s shared screen:
Those words also describe how I felt when I realized the conclusion to my seriesof blogs on the 2021 Nobel Prizes would address the topic of climate change.
The tight embrace of welcoming hugs, the cozy warmth of a crackling fireplace, the brisk chill of afternoon walks in snowy woods—these are some of the feelings that, for me, make the winter holidays one of the best times of the year. This season, I’m also choosing to be thankful for the biology that makes these sensations possible.
This year’s Nobel Prize in Physiology and Medicine went to two scientists who discovered the receptors that allow us to sense touch and temperature. Joining other sensory mechanisms recognized by the Nobel committee, these discoveries add to our knowledge of how we interact with the world around us.
Imagine a scenario—you’re studying the developmental biology of a species of squid. The squid don’t reproduce in captivity, so females carrying fertilized eggs are collected from the wild and rehomed in your lab’s aquariums. You’ve monitored all the normal aquarium conditions—pH, temperature, salinity—ensuring the animal’s new home mimics its natural environment.
But then, for no reason apparent to you, the clutch of eggs doesn’t develop and doesn’t hatch, derailing your research program until next year when you can collect more adult squid from the wild. What went wrong?
Scrolling through the October 6 headlines, enjoying my morning cup of coffee, I came across a piece of news that brought this chemist-turned-science writer a special sort of nerdy joy. The 2021 Nobel Prize in Chemistry had been announced, and I was going to get to write about a subject near and dear to my heart—catalysis and sustainability.
Soon after Amanda Capes-Davis started working with CellBank Australia, she received a request from an exasperated graduate student:
This cell line was handed down to me for my project, but I’m getting strange experimental results with the cells.Can you authenticate the cell line?
After performing genetic analyses, Capes-Davis soon had the answer to the student’s experimental woes: the cells did not come from the human tissue type the student was studying. They weren’t even human—they were mouse cells.
“She’d been given this cell line that was behaving differently than expected, and people thought ‘wow, this is an exciting new variant,’ it could tell her more about a particular disease,” Capes-Davis said. “But no, it was a more sinister reason, unfortunately.”
Wearing blue surgical gowns and white respirator hoods, research scientist Pradeep Uchil and post-doctoral fellow Irfan Ullah carry an anesthetized mouse to the lab’s imaging unit. Two days ago, the mouse was infected with a SARS-CoV-2 virus engineered to produce a bioluminescent protein. After an injection of a bioluminescence substrate, a blue glow starts to emanate from within the mouse’s nasal cavity and chest, visible to the imaging unit’s camera and Uchil’s eyes.
“We were never able to see this kind of signal with retrovirus infections.” Uchil is a research scientist at the Yale School of Medicine whose work focuses on the in vivo imaging of retroviral infections. Normally, the mouse would have to be sacrificed and “opened up” for viral bioluminescent signals from internal tissues to be imaged directly.
