An accelerated melting of ice occurred in Antarctica 9,000 years ago: the importance of the discovery

The sampling of marine sediments during the Japanese expeditions. Credit: National Institute of Advanced Industrial Science and Technology (AIST) About 9,000 years agowhen global temperatures increased with the end of the Last Ice Age, the ice ofEast Antarctica they suffered one particularly rapid fusion: the cause of this amplification was the effect of melt water on ocean circulation. The researchers ...

Signs of cryovolcanism discovered on comet 3I/ATLAS: chemistry recalls bodies beyond Neptune

Image generated with AI. Not a day goes by without the interstellar comet 3I/ATLAS providing a new surprise. As the closest to Earth on December 19thEarth’s largest telescopes are peering tirelessly at this rare visitor, trying to gather as much data as possible before it vanishes forever into cold interstellar space. The latest discoveries in chronological order suggest that 3I/ATLAS ...

Why traveling by train costs more than flying in Europe

Every year, when the time comes to organize the trip home for the holidays, many of us find ourselves in front of the PC screen consulting ticket prices and choosing whether to take the train or plane. Those who have already done so will have noticed that, this year too, generally, Train tickets cost much more than plane ticketsand Italy ...

Everything is connected: what graph theory is for and why it is the key to understanding complex systems

In recent decades, it technological development and the possibility of collecting huge amounts of data they have changed the way we look at the world. Today we have networks that can contain millions of interacting elements: networks of people, digital networks, biological networks, infrastructural networks.These systems show non-intuitive behaviorsdifficult to predict by studying only their individual parts. To understand them, ...

The experiment to make greenhouses self-sufficient and accelerate plant growth: interview with the author

The experiment to make greenhouses self-sufficient and accelerate plant growth: interview with the author

A team of researchers has successfully tested modules in perovskite with the aim of creating self-sufficient greenhouses thanks tosolar energy. Perovskite, in fact, allows you to build semi-transparent photovoltaic panelswhile in traditional photovoltaics silicon cells are used which produce a lot of energy but, being opaque, can penalize the growth of crops. The results of this experiment are promising and ...
