The future of solar energy

Today's silicon solar panels are an industry standard, but these rigid, heavy blocks may be shunted aside by plastic rivals – lightweight, flexible solar panels that could be printed and stuck onto buildings or placed in windows or cars, turning light into electricity in locations inaccessible to their heavier cousins.

Amazing Scientific Facts

DNA

Have you ever wondered what's the length of information encoded in our genetic memory? One extraordinary way to put it follows like that: there are over 3 billion base pairs of DNA in human genes and over 25,000 genes in the human genome. An entire copy of that genome exists in each of the 10 trillion cells in the human body. If all of that DNA were lined up, it would cover the distance between Earth and the sun 100 times, which is 152.03 million km x 100 = 15,2 billion kilometers.

15,000-year-old viruses discovered in Tibetan glacier ice

Most of the viruses were previously unknown to humans, study finds

Scientists who study glacier ice have found viruses nearly 15,000 years old in ice samples from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date.

The findings, published in Microbiome, could help scientists understand how viruses have evolved over centuries. The researchers also created a new, ultra-clean method of analyzing microbes and viruses in ice without contaminating it.

Natural Sciences and humanity

Two of the most human characteristics are sharing and curiosity. They led us to discover the universe inside us as well as outer space. Since the beginning of Western Civilization, all the philosophers were obsessed with studying and discussing the essence of Nature. We could say that Earth & Planetary Sciences started back there in Ancient Greece with the works of Democritus and walked a long way through Galileo, Copernicus, Newton, Einstein, and Stephen Hawking. The more we explore, the bigger grows our perception of the worlds beyond. Every single piece of extant matter on planet Earth contains the DNA of the entire Universe. We could only imagine how much pivotal knowledge, how many alternative energy sources, and important answers are waiting still hidden for us. Future lies out there in the vast cosmic ocean as Carl Sagan loved to say. Nowadays, these words sound even more relevant since we faced the limits of our home planet and the need to develop new sustainable solutions for the current environmental and social problems. The welfare of future generations depends on our mutual endeavors.

First-ever detection of a black hole merging with a neutron star

A long time ago, in two galaxies about 900 million light-years away, two black holes each gobbled up their neutron star companions, triggering gravitational waves that finally hit Earth in January 2020.

Discovered by an international team of astrophysicists including Northwestern University researchers, two events -- detected just 10 days apart -- mark the first-ever detection of a black hole merging with a neutron star. The findings will enable researchers to draw the first conclusions about the origins of these rare binary systems and how often they merge.
