Periodontitis is a serious chronic inflammatory form of gum disease that affects millions worldwide. It can lead to tooth loss and the destruction of supporting bone. This disease has also been linked to other health problems, including diabetes, respiratory infections, and heart disease, impacting quality of life and increasing health care costs.
Current treatments target bacterial infection and inflammation through nonsurgical therapies, such as scaling and root planing, commonly known as “deep cleaning.” However, they do not repair the gum’s extracellular matrix (ECM), the gingival tissue’s structural support that is damaged by chronic inflammation. Without this foundation, gingival tissue cannot function properly, allowing inflammation to persist and slowing healing.
Now, new research led by Kyle H. Vining and Hardik Makkar of the School of Dental Medicine demonstrates how the physical properties of the gingival tissue impact periodontal health and disease. Their findings are published in Advanced Materials.
Watch live here!! Artemis II, NASA’s first crewed Moon mission in over 50 years, will launch astronauts around the Moon aboard the Orion spacecraft using the powerful SLS rocket. This historic NASA lunar mission will test deep-space life-support systems, high-speed Earth reentry, and the next phase of the Artemis program leading to the Artemis III Moon landing. The Artemis 2 crew—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—will travel farther from Earth than any humans in decades, performing a lunar flyby, systems checkout, and deep-space trajectory critical for future Moon to Mars exploration. This mission is a major milestone for NASA Artemis, lunar exploration, Moon mission timeline, and the return of humans to the lunar surface. Space fans are watching for updates on Artemis II launch date, SLS rocket tests, Orion spacecraft performance, and NASA livestream coverage. Artemis II is the flagship NASA Artemis mission that will send the Artemis 2 crew of four Artemis II astronauts on a historic crewed lunar mission aboard the Orion spacecraft, launched by NASA’s powerful SLS rocket. This mission includes a precise lunar flyby and marks a major milestone in the Artemis program, advancing NASA’s long-term Moon to Mars strategy. As part of the modern NASA Moon mission campaign, Artemis II will test deep-space systems critical for future lunar exploration, including the planned Artemis 3 Moon landing. Space fans tracking the Moon mission timeline are watching closely for the official Artemis 2 launch date, major NASA spaceflight updates, and the upcoming NASA livestream. Expect major space news 2025 announcements as NASA releases each Moon mission update and continues preparing for humanity’s return—returning to the Moon for the first time in more than 50 years. Artemis Launch Live: Everything You Need to Know About NASA’s Return to the Moon. The Artemis launch live event marks one of the most anticipated moments in modern spaceflight, as NASA prepares for a historic rocket launch today live from Kennedy Space Center Florida. This mission to the moon 2026 is part of the broader Artemis program, designed to return humans to the Moon for the first time since Apollo 17, the last moon mission in 1972.
The Artemis 2 mission is NASA’s first crewed flight in the Artemis program, following the success of Artemis 1 launch. Unlike earlier missions, Artemis II will not land on the moon, but instead will send astronauts aboard the Orion capsule on a deep-space journey around the Moon.

Background and ObjectivesMultiple sclerosis (MS) is a chronic progressive, demyelinating autoimmune CNS disease. Autoantibodies to the motif P-(SA)-x-(SGA)-R-(SN)-(LRKH) are a class of predictive markers specific to MS that could add to emerging…
Signaling is fundamental to how cells sense and respond to their environment—but in immune cells, those signals must be precisely amplified to mount an effective defense against invasive threats. New research by immunologists in Germany is shedding light on how that amplification occurs in T cells, revealing a key molecular mechanism that helps trigger immune responses—and may also contribute to inflammatory conditions.
Writing in Science Signaling, researchers at the University Medical Center Hamburg-Eppendorf identified a crucial step in the production of a “second messenger,” an internal signal that relays and amplifies messages received at the cell surface. Because external signaling molecules cannot enter the cell, second messengers translate those cues into powerful intracellular responses.
In T cells, that process depends on NAADP (nicotinic acid adenine dinucleotide phosphate), a molecule that drives calcium (Ca²⁺) signaling—an essential step in T cell activation. Without it, T cells cannot become the effector cells needed to fight serious threats, such as infections or cancer.

Artemis II Moon Rocket Launch LIVE: NASA’s Artemis II Live Views from Kennedy Space Center, FL | CNBC TV18 LIVE feed from Kennedy Space Center in Florida will provide continuous views of the Artemis II Moon rocket beginning on Thursday, March 19, with rollout from the Vehicle Assembly Building to Launch Pad 39B. NASA Sends Astronauts around the Moon for the first time in 50 years. Live view of the Artemis II Moon rocket. While the Artemis II launch window opens as early as Wednesday, April 1, the mission management team will assess flight readiness across the spacecraft, launch infrastructure, and the crew and operations teams before selecting a launch date. NASA’s Artemis II mission is scheduled to lift off from Kennedy Space Center on April 1. The two-hour launch window starts at 6:24 p.m. EDT (2224 UTC). Four astronauts — three from NASA and one from the CSA (Canadian Space Agency) — make up the Artemis II crew: NASA astronaut Reid Wiseman, Artemis II commander. NASA astronaut Victor Glover, Artemis II pilot. NASA astronaut Christina Koch, Artemis II mission specialist. Canadian Space Agency (CSA) astronaut Jeremy Hansen, Artemis II mission specialist. After launching into space atop NASA’s Space Launch System (SLS) rocket, the crew will journey around the Moon and back in their Orion spacecraft, named Integrity, on an approximately 10-day mission. Artemis II will be the first crewed flight test of SLS and Orion, testing the technologies we’ll need for long-term lunar exploration and human missions to Mars. #nasa #artemislaunch #artemis2 #nasaastronauts #rocketlaunch #cnbctv18 #livestream.
