Accelerating Clean Energy Transitions to Safeguard Human Health and Survival.

The year 2023 was the warmest year in the 174-year global instrumental record. The year was also marked by a series of climate-related extreme events, including heat waves, storms, and wildfires that caused widespread economic and health impacts. The 28th Conference of the Parties of the United Nations Framework Convention on Climate Change called for transitioning away from fossil fuels and accelerating action in this critical decade.

Ecology of vertical tumor transmission in the freshwater cnidarian Hydra oligactis.

Transmissible tumors are increasingly regarded as a new form of parasitic life, but relatively little is known about the ecology and evolution of their interactions with their host. In this work, we provide new insights into transmission dynamics of vertically transmitted tumors in the freshwater cnidarian Hydra oligactis. First, we found tumoral hydra to be infectious at any age, regardless of whether they were in their asymptomatic or symptomatic phases, with the bacteriome composition remaining constant during both phases.

Decellularized Macroalgae as Complex Hydrophilic Structures for Skin Tissue Engineering and Drug Delivery.

Due to their indisputable biocompatibility and abundant source, biopolymers are widely used to prepare hydrogels for skin tissue engineering. Among them, cellulose is a great option for this challenging application due to its increased water retention capacity, mechanical strength, versatility and unlimited availability. Since algae are an unexploited source of cellulose, the novelty of this study is the decellularization of two different species, freshly collected from the Black Sea coast, using two different chemical surfactants (sodium dodecyl sulphate and Triton X-100), and characterisation of the resulted complex biopolymeric 3D matrices.
