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.

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 […]
The El Niño Southern Oscillation (ENSO) is one of the most important modes of climate variability worldwide, with large impacts on the weather conditions in many regions, and thus on agriculture and economy. It is related to changes in the sea surface temperatures in the Tropical Pacific Ocean. Periods with higher temperatures cause the so-called […]
Flash thought to result from black hole swallowing a star Two separate teams of scientists, who have published papers in Nature and Nature Astronomy, have concluded that a flash of light that appeared in February was the astrophysical jet that erupted from a massive black hole as it swallowed a star. “From the data we […]
For the first time, scientists have entangled atoms for use as networked quantum sensors, specifically, atomic clocks and accelerometers. The research team’s experimental setup yielded ultraprecise measurements of time and acceleration. Compared to a similar setup that does not draw on quantum entanglement, their time measurements were 3.5 times more precise, and acceleration measurements exhibited […]
