Four Russian warships including a nuclear submarine have reached Cuba, just 200 miles off the coast of Florida, ahead of a planned military exercise in the Atlantic. The fleet — made up of a frigate, a nuclear-powered submarine, an oil tanker and a rescue tug — arrived in Havana Bay on Wednesday, welcomed by a 21-cannon salute from Cuba. Dramatic images from the arrival show the ominous and massive vessels entering the bay as Cubans lined up on…

In a study appearing in Nature, an international team of researchers led by the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, reconstructed the evolutionary history and global spread of malaria over the past 5,500 years, identifying trade, warfare, and colonialism as major catalysts for its dispersal.

Prototype quantum photonic-dimer laser uses entanglement to bind photons and deliver a powerful beam of concentrated light that can shine through adverse weather like thick fog.

ARLINGTON, Va. – U.S. military researchers are approaching industry to enhance atomic vapor sensors for electric field sensing, imaging, communications, and quantum information science (QIS).

Officials of the U.S. Defense Advanced research Projects Agency (DARPA) in Arlington, Va., have issued a broad agency announcement (HR001124S0031) for the Enhancing Quantum Sensor Technologies with Rydberg Atoms (EQSTRA) program.

EQSTRA seeks to enhance the performance, capabilities, and maturity of atomic vapor sensors for future compact, calibration-free, small, and lightweight devices with low drift, and quantum-limited accuracy and sensitivity.

A new study confirmed that a 3500-year-old Mycenaean suit of armor was combat-ready, as evidenced by tests with Greek Marines enduring a rigorous combat simulation, highlighting its significant role in Mycenaean military prowess.

A study recently published in the open-access journal PLOS ONE reveals that a famous Mycenaean suit of armor was designed for extended combat, not just for ceremonial purposes. The research, conducted by Andreas Flouris and colleagues at the University of Thessaly in Greece, supports its use in active warfare.

One of the oldest known suits of European armor is a 3500-year-old suit found near the village of Dendra, a few kilometers away from ancient Mycenae. Since its discovery in 1960, it has been unclear if this was a ceremonial suit or if it was suitable for battle. This question has important implications for understanding warfare in Late Bronze Age Europe, but no historical accounts describe the use of this style of armor. In this study, researchers combine historical and experimental evidence to investigate the combat suitability of the Dendra armor.

When placed at the tip of a turbine blade, the c-shaped “winglet” inspired by the condor reduces drag, potentially increasing the turbine’s efficiency by up to 10% in optimal conditions, according to a study published in the journal Energy.

The wings of soaring birds have also been adapted for use in commercial and military aircraft around the world to increase their lift, says co-author Brian Fleck, a professor of mechanical engineering and expert in fluid dynamics.
