Along with COVID-19 and the flu, respiratory syncytial virus (RSV) has spread at alarming rates in recent months.
Promising vaccine candidates for this common infection are now winding down their large-scale clinical trials. These vaccine candidates rely on a key advance made by Barney Graham, Jason McLellan, and colleagues in 2013. That year, Graham and McLellan, who later used similar approaches to make key contributions to the COVID-19 vaccines, provided the proof of concept for a new way of developing vaccines based on leveraging insights from structural biology. Together with colleague Man Chen, they made discoveries that paved the way for RSV vaccines that have neared the finish line, a feat Science Magazine named as a runner-up for the 2022 Breakthrough of the Year.
Come join Science Magazine on 1 March at 1 p.m. ET to hear Graham, McLellan, and Chen discuss how the approach they described in 2013 is leading to what could be the first ever FDA-approved vaccines against RSV, as well as other RSV therapeutics. Gregory Zuckerman, author of multiple best-selling books, including A Shot to Save the World: The Inside Story of the Life-or-Death Race for a COVID-19 Vaccine, will share his perspective on this milestone.
This event is being co-organized with the University of Texas, Austin, as part of their second Texas Science Festival.

Science News Video: Scientists turn dead stars into living laboratories called pulsar timing arrays
Read the Perspective: https://www.science.org/doi/10.1126/science.abq1187
In order to detect the background hum of gravitational waves in the cosmos, scientists monitor the light coming from dead stars called pulsars. These pulsar produce flashes of light with incredible regularity, allowing researchers to calculate when they would expect to detect these flashes. The difference between the the expected actual arrival time of these flashes is caused by small ripples in space-time caused by gravitational waves. Researchers are looking at these differences across dozens of pulsars, called pulsar timing arrays, for confirmation of the gravitational wave background.

Science News Video: JWST's golden eye sees the universe anew
Not many telescopes get introduced by the president, but JWST, the gold-plated wunderkind of astronomy built by NASA with the help of the European and Canadian space agencies, deserves that honor. It is the most complex science mission ever put into space and at $10 billion the most expensive. And it did not come easy.

Science News Video: See where echidnas’ bodies are hot — and where they’re not | Science News
When tiny glass frogs fall asleep, they store almost 90 percent of their red blood cells in their liver, increasing the animals’ transparency (seen in the first clip), which may help hide them from predators. When the animals wake up, their blood starts to course again (second clip).

Science News Video: Genital spines keep a male wasp from becoming a frog’s snack | Science News
Two thin spines shown flexing on a male mason wasp’s rear don’t deliver sperm. But these spines are among the few known genital structures that work as self-defense, ecologists Shinji Sugiura and Misaki Tsujii of Kobe University report. Male Anterhynchium gibbifrons mason wasps don’t have stingers, but when a tree frog gulps the male, lunch doesn’t go well. The wasp stabs its spines into the frog’s face and mouth — prompting the frog to vigorously spit out the wasp.

On September 27, 2021, Perseverance’s navigation camera spotted a dust devil (purplish cloud in the images at top, which were processed to reveal the dust) whirling toward it from 50 to 60 meters away. As the whirlwind swept across the rover, Perseverance’s microphone recorded the sound it made, capturing the first-ever audio of a Martian dust devil (middle), and the rover’s instruments detected a slight drop in atmospheric pressure (bottom). These data may someday help researchers better understand dust dynamics on Mars.
