Expiring medications could pose challenge on long space missions

Medications used by astronauts on the International Space Station might not be good enough for a three-year journey to Mars. A new study led by Duke Health shows that over half of the medicines stocked in space—staples such as pain relievers, antibiotics, allergy medicines, and sleep aids—would expire before astronauts could return to Earth.

Effects of stellar magnetism could expand criteria for exoplanet habitability

Interest in Earth-like planets orbiting within the habitable zone of their host stars has surged, driven by the quest to discover life beyond our solar system. But the habitability of such planets, known as exoplanets, is influenced by more than just their distance from the star.

Scientists resolves a long-debated anomaly in how nuclei spin

Atomic nuclei come in different shapes, varying from football-like (“prolate”) to pancake-like (“oblate”). Prolate and oblate shapes have different moments of inertia. This is a body’s resistance to having its speed of rotation altered by an external force. Atomic nuclei having different shapes with different moments of inertia implies that it takes different amounts of […]

Sensing ultraviolet light with the help of molecular switches

The old saying “the dose makes the poison” also holds true for ultraviolet (UV) light. While UV light is essential for vitamin D production, it is also important in phototherapy, several industrial processes, and plant growth. It also has harmful effects such as premature skin aging and cancer.

Two-in-one mapping of temperature and flow around microscale convective plumes

Researchers from Tokyo Metropolitan University have devised a way to measure both the temperature and velocity profiles of fluid in a convective plume at millimeter length scales in 3D. They combined near-infrared absorption imaging and image processing to separate the motion of tracer particles from snapshots of how light is absorbed, producing both a smooth […]

Tuning into the frequencies of conical shells: Research reveals a fluid-structure symphony

Truncated conical shells are essential in industries such as aerospace and marine engineering, where understanding their dynamic behavior is crucial. Traditional research has primarily focused on cylindrical shells, leaving a gap in the literature regarding conical structures.

Scientists discover energy and pressure analogies linking hadrons, superconductors and cosmic expansion

Quantum chromodynamics (QCD) is the theoretical framework for studying the forces within atomic nuclei and their constituent protons and neutrons. A major part of QCD research involves how quarks and gluons are contained within nucleons (protons and neutrons).
