Researchers have found the trigger behind a powerful bacterial defense against viruses. Viruses that prey on bacteria could become an increasingly important tool for treating bacterial infections, particularly as antibiotic resistance makes some infections harder to control. These viruses, known as bacteriophages (phages), can infect and destroy harmful bacteria without damaging human cells. Using phages […]
NASA Captures a Strange Formation on Earth With a Surprising Lunar Connection
A NASA astronaut captured a stunning 600-million-year-old rock formation in Madagascar that shares a surprising geological connection with the Moon. A striking patch of bright rock in southern Madagascar has an unexpected connection to the Moon. Surrounded by rocks that were twisted and stretched by ancient geological forces, the formation contains anorthosite, the same type […]
This “Lightsaber” Beam Is Actually a Working Radio Antenna
A plasma antenna resembling a lightsaber has transmitted radio waves and could let future spacecraft retune and redirect their antennas by adjusting a laser. Changing a radio antenna’s length can be difficult in space exploration equipment, even though that dimension helps determine which frequencies it can transmit and receive. Researchers have now demonstrated a possible […]

Webb Discovers Something Extraordinary in the Clouds of a World With No Sun
A world with no sunrise still has changing skies, and Webb has caught its water clouds thickening and thinning just 7.5 light-years away. Astronomers have tracked weather on WISE 0855, the coldest known brown dwarf, using the James Webb Space Telescope. A team led by Brittany Miles of the University of Arizona’s Steward Observatory watched […]
Vanilla’s Sweet Secret Could Help Heal Stubborn Wounds
Vanillin could help form wound-care materials while supplying antibacterial activity, a combination made more practical by its low-cost and abundant supply. The compound behind vanilla’s sweet aroma could become an ingredient in wound-care materials. A team from Flinders University’s Biomedical Nanoengineering Laboratory has found that vanillin has pronounced antioxidant, anti-inflammatory, and antibacterial properties, making it […]
