Using future projections of the latest generation of Earth system models, a U.S. National Science Foundation-supported study published in Science Advances found that most of the world's ocean is steadily losing its year-to-year memory under global warming.

"We have leveraged the ocean's memory to help us assess future changes in Earth's systems on a seasonal to decadal timescale," said Varavut Limpasuvan, a program director in NSF's Division of Atmospheric and Geospace Sciences. "Now, memory loss and its impact on sea surface temperature suggest that, going forward, we may have to be less reliant on the ocean as a predictor, which too is suffering from a warming world."

It is curious how really old, even ancient, ideas that were purely speculative could reemerge once again but this time proposed by the archetypal enemy of speculation – Science. In the 5th century BC, the Greek philosopher Anaxagoras claimed that life exists throughout the Universe and is distributed by the means of space dust, meteoroids, asteroid, comets, etc. This theory is called Panspermia (from Ancient Greek πᾶν (pan) 'all ', and σπέρμα (sperma) 'seed' ).

Now, twenty-five centuries later, a new method for examination of meteorites gives a boost to the notion that all the vital chemical components required for the formation of life may have been delivered from outer space.

1. "We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.' We had all simultaneously realised that our home was not limitless – there was an edge to our existence."

2. "For life to truly thrive on this planet, there must be immense biodiversity. Only when billions of different individual organisms make the most of every resource and opportunity they encounter, and millions of species lead lives that interlock so that they sustain each other, can the planet run efficiently. The greater the biodiversity, the more secure will be all life on Earth, including ourselves. Yet the way we humans are now living on Earth is sending biodiversity into a decline."

More than 25 centuries ago, Pythagoras of Samos held the belief that the planets move according to mathematical equations. Thus they resonate to produce musical symphonies. These symphonies are inaudible unless one follows his teaching and develops the senses to hear them. It is claimed that Pythagoras was able to hear the music of the planets while meditating under the night sky. It may sound like mysticism but it is a concept well-adopted by modern scientists. Sure, they don't meditate or follow some guru's teachings. Scientists use observatories, telescopes, and super-computers. However, the idea remains the same. The Universe is the greatest musical composition made by Nature itself.

Traditional energy production in advanced economies involves the importation of large amounts of oil and gas from a small number of suppliers. Renewable energy systems under new community ownership structures are being pioneered all over the Europe. The goal is to develop cheap, clean and secure energy by bringing power generation closer to the people who will use it.

Squeezed between the war in Ukraine, the pandemic and climate change, the European energy system is experiencing an unprecedented crisis. Bill payers are coping with sharp increases in energy prices which show no signs of abating. In the second half of 2021, average prices for electricity (and gas) jumped by more than 11% in the EU, compared to the same period in 2020, according to Eurostat electricity price statistics. That was before the geopolitical crisis arising from the invasion of Ukraine by Russia in late February prompted sanctions which further squeeze energy supply.
