Plastics are ubiquitous in our society, found in packaging and bottles as well as making up more than 18% of solid waste in landfills. Many of these plastics also make their way into the oceans, where they take up to hundreds of years to break down into pieces that can harm wildlife and the aquatic […]
Over two-thirds of world’s glaciers will melt by 2100 More than two-thirds of the world’s glaciers will disappear by 2100 if the climate continues to warm at current trends. The global temperature is on track to rise 2.7 degrees Celsius over pre-industrial levels by the end of the century, but scientists note that if future […]

Last year’s Nobel Prize in Physics celebrated the fundamental interest of quantum entanglement, and also envisioned the potential applications in “the second quantum revolution” — a new age when we are able to manipulate the weirdness of quantum mechanics, including quantum superposition and entanglement. A large-scale and fully functional quantum network is the holy grail […]
Bering Land Bridge formed surprisingly late during last ice age A new study shows that the Bering Land Bridge, the strip of land that once connected Asia to Alaska, emerged far later during the last ice age than previously thought. Full Story: Princeton University Exotic clasts in Chang’e-5 samples indicate unexplored terrane on moon The […]
How did the complex organisms on Earth arise? This is one of the big open questions in biology. A team of researchers has come a step closer to the answer. The researchers succeeded in cultivating a special archaeon and characterizing it more precisely using microscopic methods. This member of the Asgard archaea exhibits unique cellular […]
NASA ends Mars InSight lander mission after 4 years NASA has officially concluded its InSight lander mission on Mars after the spacecraft’s solar panels accumulated too much dust and has stopped transmitting information on the planet’s geologic makeup and activity. After an “enormously successful mission,” InSight is “going to sit on Mars and enjoy the […]

Water has puzzled scientists for decades. For the last 30 years or so, they have theorized that when cooled down to a very low temperature like -100 ºC, water might be able to separate into two liquid phases of different densities. Like oil and water, these phases don’t mix and may help explain some of […]
Astronomers identify 2 planets as possible water worlds Using data from the Kepler, Hubble and Spitzer space telescopes, astronomers have identified two exoplanets orbiting a red-dwarf star 218 light-years away suspected of being made mostly of water. “It is the first time we observe planets that can be confidently identified as water worlds, a type […]
The biochemical process by which cyanobacteria acquire nutrients from rocks in Chile’s Atacama Desert has inspired engineers to think of new ways microbes might help humans build colonies on the moon and Mars. Researchers used high-resolution electron microscopy and advanced spectroscopic imaging techniques to gain a precise understanding of how microorganisms modify both naturally occurring […]
Radioactive meteorites could have brought life to Earth The gamma rays produced by carbonaceous chondrites, radioactive meteorites that contain water and organic compounds, could have been sufficient to spark the chemical reactions that created amino acids, the building blocks of life on Earth, researchers have concluded. The study is based on observations from bombarding chemicals […]
