The end-Ordovician mass extinction, the first of the ‘Big Five’ mass extinctions occurred 445 million years ago and was characterized by the disappearance...
Using the Immersion GRating INfrared Spectrometer (IGRINS) at the Gemini South Observatory on Cerro Pachon, Chile, astronomers have measured carbon-to-hydrogen...
Green tea is one of the most widely consumed beverages worldwide. Green tea catechins are associated with a delay in aging. In experiments performed in...
People with more severe obstructive sleep apnea and reductions in blood oxygen concentrations are more likely to have elevated concentrations of triglycerides...
A team of researchers from the United States and Austria has analyzed remnants of ancient asteroids and modeled the effects of their violent collisions...
Biologists at the Ludwig-Maximilians-University Munich have developed a method that allows tadpoles of African clawed frogs (Xenopus laevis) to ‘breathe’...
Observations by the NASA/ESA Hubble Space Telescope in far-ultraviolet light of Jupiter’s icy moons were used in the past to detect molecular oxygen...
A team of researchers led by the University of New South Wales has discovered that suspensions of gallium liquid metal — a soft, silvery-white metal...
Using machine learning, a team of physicists at Lawrence Livermore National Laboratory has studied the phase behaviors of superionic water — a phase...
Jupiter’s icy satellite Ganymede is the largest moon in the Solar System. Water ice on its surface is frozen solid in frigid temperatures as low as minus...
The one-atom thin 2D magnet, created by Dr. Jie Yao from the University of California, Berkeley, and the Lawrence Berkeley National Laboratory, and his...
Earth’s sphere tilts on its axis at an angle of 23.5 degrees; this gives us our seasons, with parts of the planet receiving more direct sunlight in summer...
In 2011, planetary researchers using samples of the solar wind collected by NASA’s Genesis spacecraft found that solar system planetary bodies have a...
Inspired by natural history observations in Haiti and Costa Rica, a team of biologists from the University of Toronto and elsewhere conducted experiments...
Atmospheric oxygen is thought to have played a vital role in the evolution of complex multicellular organisms. The so-called oxygen control hypothesis...
On April 20, 2021, the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) instrument aboard NASA’s Perseverance rover converted some of carbon...
Oxygen levels fluctuated dramatically for about 200 million years after the start of the Great Oxidation Event, with permanent atmospheric oxygenation...
A team of U.S. physicists has created a new isotope of fluorine, fluorine-13 (13F), via a charge-exchange reaction between a beam of oxygen-13 (13O) and...
A team of scientists at the Ohio State University has found that steady electrical stimulation generates increased permeability across blood vessels, an...
Martian atmospheric oxygen, carbon, nitrogen and argon ions have been escaping Mars for billions of years and could be preserved inside the uppermost hundreds...
