A Lifetime on Mars: The Adventures of Spirit and Opportunity – S4E4

Transcript (music) Narrator: From Earth, the planet Mars looks like a red star in the night sky, a beacon that signals one of the most accessible alien worlds. Not only is Mars relatively close to us in the solar system, but it has a landscape where we can find a footing. Mars seems almost benign compared to the metal-melting heat of Venus, or gas giant planets like Jupiter that vaporize any craft that dares enter its intense atmosphere. And yet, Mars is known as “the death planet” because so many missions attempting to reach it have failed. When NASA…

How Lying In Bed For 60 Days Helps Astronauts

Episode description:  In space, microgravity changes the body. Body fluids shift from the legs toward the head, the back of our eyes flatten, we lose muscle strength, our bones lose some of their density, and even the amount of blood pumped by the heart with each beat drops. To learn more about how microgravity affects the human body and develop new ways to help astronauts stay healthy, scientists are asking dozens of volunteers to spend 60 days in bed with their heads tilted down at a specific angle. This research approach tricks the body into reacting very similarly to…

Tylenol in pregnancy linked to higher autism risk, Harvard scientists report

Researchers reviewing 46 studies found evidence linking prenatal acetaminophen (Tylenol) exposure with higher risks of autism and ADHD. The FDA has since urged caution, echoing scientists’ advice that the drug be used only at the lowest effective dose and shortest duration. While important for managing fever and pain in pregnancy, prolonged use may pose risks to fetal development. Experts stress careful medical oversight and further investigation. Source link

Launching Into Action: White Sands Firefighters on the Frontlines of New Mexico’s Wildfire Crisis

Ruidoso, New Mexico lay in an unusual hush on June 20, 2024. During any normal summer day, the village in the southern part of the state lives up to the Spanish translation of its name — noisy.  But the bustle of this vacation hotspot, which attracts nearly 2 million visitors each year, was stifled by a mandatory evacuation order issued as wildfires raged unchecked across Lincoln County and the Mescalero Apache Reservation.  After four days of fires, news of the disaster began spreading to surrounding communities. At NASA’s White Sands Test Facility (WSTF), Fire Department Deputy Chief James Herrera and…

NASA to Launch Three Rockets from Alaska in Single Aurora Experiment

UPDATE March 31, 2025: The third and final rocket of the AWESOME mission launched on Saturday, March 29 at 1:30 a.m. AKDT. The payload systems functioned properly with a yet-to-be-determined issue with TMA release resulting in a single persistent upleg trail instead of modulated upleg and downleg trails. The vapor trail was still usable and will likely still meet mission success criteria. This concludes the AWESOME mission campaign. UPDATE March 26, 2025: Two of the three AWESOME mission rockets launched on Tuesday, March 25 at 3:52 a.m. AKDT and 4:30 a.m. AKDT. The PI reports that both rockets launched into good science conditions and…

A tiny enzyme may hold the key to safer pain relief

Researchers have uncovered a surprising way the brain switches pain on, revealing that neurons can release an enzyme outside the cell that activates pain signals without disrupting normal movement or sensation. This enzyme, called VLK, modifies nearby proteins in a way that intensifies pain and strengthens connections tied to learning and memory. Removing VLK in mice dramatically reduced post-surgery pain while leaving normal function untouched, offering a promising path toward safer, more targeted pain treatments. Source link
