From the “Alligator” to the LCAC: How Amphibious Military Vehicles Evolved in Time

In recent times, amphibious warfare returned to prominence, with many military operations around the world being conducted by amphibious troops. From D-Day to Ukraine, marines from different countries have a long history of successful deployment in war theatres, mainly due to their preparation and their capabilities. Readiness, flexibility, and cross-domain operativity are the basic features of amphibious units, which find themselves fighting in one of the most difficult types of warfare. Sea, land, air, space, and cyberspace are all fundamental domains to organising and carrying out a successful amphibious operation. For this reason, to operate in such a complex and multifaceted environment, amphibious units benefit from unique vehicles and assets that help them in their operations.


Assessing Africa-EU Relations vis-à-vis Russian Influence in Africa

This paper will analyse to what extent Africa past relations with Russia and the West have affected present African geopolitics. To reach this goal an historical overview of the legacy of the USSR will be provided, complementing this theoretical part with the effects that the colonial legacy still produces, hampering EU-Africa relations. Following this, in order to assess future developments in Russia-Africa relations, it is fundamental to evaluate the implications of the food and economic crisis in Africa as a result of the Russian invasion of Ukraine, as well as evaluating the effects of the recovery of many European countries with energetic ties with Africa after Russia’s weaponization of the energy policies. Finally, this research paper aims to provide some recommendations to strengthen Africa-EU relations in the near future as a result of the window of opportunity opened by the Russia-Ukraine war.

Consequences of the War in Ukraine on the Arctic

The desire to access the Arctic's vast mineral reserves has always been a major driver of international attention towards the region. The Arctic is believed to contain 1,699 trillion cubic feet of natural gas and various other fuels, equal to the entirety of Russia’s oil reserves and three times those of the US (U.S Geological Survey, 2008). On top of this, by 2050, it is believed that the region above the Polar Circle may be completely ice-free, considering the rate at which the ice sheet is shrinking and the multiplier effect of warming seas and surface temperatures (La Rocca, 2022). This potential development could further increase the international race for Arctic raw materials.

The EU Energy Security: Challenges and Opportunities

Europe is experiencing an unprecedented energy crisis since Russia’s invasion of Ukraine started. This is highlighting the challenges that the continent is facing, especially concerning energy. This is one of the reasons why energy security plays a central role in the common security plans of the EU and NATO allies.

Swarms of multi-legged robots overcome difficult land challenges 

Currently, ground-based robots are accustomed to moving in relatively simple environments due to their lack of locomotor capacity needed to traverse more complex terrain. For this reason, robotics engineer Yasemin Ozkan-Aydin, Professor of Electrical Engineering at the University of Notre Dame, drew inspiration from the collective behaviour of ants, bees, and birds to solve problems and overcome obstacles to develop collaborative legged robots mimicking their counterparts from the natural world.
