From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can't be seen is the battle raging underfoot to re-shape Earth. Water is eating away at the Antarctic ice, melting it where it hits the oceans. As the ice sheets slowly thaw, water pours into the sea — 130 billion tons per year for the past decade. That's the weight of more than 356,000 Empire State Buildings.
Researchers have developed a novel three-dimensional, multiscale and multicomponent model of the endothelial cell monolayer, the inner lining of the artery, to identify the cellular mechanisms involved in cardiovascular diseases. New research based on the model is able to identify the main cellular pathways involved in the initiation and progression of the disease.
From the International Space Station, astronaut Samantha Cristoforetti took this photograph of Chicago and posted it to social media. Crewmembers on the space station photograph the Earth from their unique point of view located 200 miles above the surface as part of the Crew Earth Observations program. Photographs record how the planet is changing over time.
This 40x photo shows a sagittal brain slice with cell nuclei and Purkinije cells expressing EGFP. It received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using confocal microscopy.
Engineers at Oregon State University have completed one of the most precise evaluations yet done about the impact of a major tsunami event on the Columbia River, what forces are most important in controlling water flow and what areas might be inundated.
NASA astronaut Barry Wilmore works outside the International Space Station on the first of three spacewalks preparing the station for future arrivals by U.S. commercial crew spacecraft, on February 21, 2015. Fellow spacewalker Terry Virts, seen reflected in the visor, shared this photograph on social media.
This 5x photo of an ant carrying its larva received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using reflected light and focus stacking.
This 6x photo of a pseudomorph of conichalcite after azurite received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using transmitted light.
Physicist Ernest Sternglass, whose research helped make it possible for the world to see the first moon walk, has died at age 91 of heart failure. His research helped lead to a sensitive television camera tube that captured low-light lunar action during the 1969 moon landing and U.S. astronaut Neil Armstrong's historic first steps.
A solar filament erupted from the sun in the shape of a twisted arch, and the activity in the lower corona was caught in a wavelength of extreme ultraviolet light. The event occurred over a three-hour period on February 4, 2015, with most of the filament falling back into the Sun. Filaments are notoriously unstable.
In this new ESO image, nightfall raises the curtain on a theatrical display taking place in the cloudless skies over La Silla. In a scene humming with activity, the major players captured here are Comet Lovejoy, glowing green in the center of the image; the Pleiades above and to the right; and the California Nebula, providing some contrast in the form of a red arc of gas directly to the right of Lovejoy.
This 40x photo of a rotifer shows the mouth interior and heart-shaped corona. It won 1st Place in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using differential interference contrast.
Valentine's Day is special for NASA's Voyager mission. It was on February 14, 1990, that the Voyager 1 spacecraft looked back at our solar system and snapped the first-ever pictures of the planets from its perch at that time beyond Neptune. This "family portrait" captures Neptune, Uranus, Saturn, Jupiter, Earth and Venus from Voyager 1's unique vantage point.
Researchers have developed a new, automated method for classifying hundreds of kilometers of the deep sea floor, in a way that is more cost efficient, quicker and more objective than previously possible, estimating geographic distribution of life on the sea floor using a combination of submarine mapping technology, statistics and a landscape ecology technique called Niche Theory.
This image from the Landsat-8 satellite acquired on September 23, 2014, brings us over the southwest United States: Nevada and Arizona. Las Vegas with its grid-like urban plan is visible near the center. Sitting in a basin of the Mojave Desert, the city is surrounded by a number of mountain ranges.
Galaxies can take many shapes and be oriented any way relative to us in the sky. This can make it hard to figure out their actual morphology, as a galaxy can look very different from different viewpoints. A special case is when we are lucky enough to observe a spiral galaxy directly from its edge, providing us with a spectacular view like this one.
This 4x photo shows active fluid flow around a coral polyp (P. damicornis). It won 6th Place in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using fluorescence and autofluorescence.
European Space Agency astronaut Samantha Cristoforetti, who is working and living on the International Space Station as part of Italy’s Futura mission, took this photograph from the International Space Station. Cristoforetti wrote, "A spectacular flyover of the Gulf of Aden and the Horn of Africa. #HelloEarth"
This 417x photo shows a rotifer (Conochilus unicornis) actively feeding — this rotifer species forms a free floating spherical colony. It won 13th Placein the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using differential interference contrast.
NASA's Curiosity Mars rover can be seen at the "Pahrump Hills" area of Gale Crater in this view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. Pahrump Hills is an outcrop at the base of Mount Sharp. The region contains sedimentary rocks that scientists believe formed in the presence of water.
New NASA/ESA Hubble Space Telescope images capture a rare occurrence, as three of Jupiter’s largest moons parade across the giant gas planet’s banded face. Hubble took a string of images of the event which show the three satellites — Europa, Callisto and Io — in action. The planet's four moons can commonly be seen transiting the face of Jupiter. However, seeing three of them transiting at the same time is rare.
This image from Sentinel-1A’s radar shows the metropolitan area of Portugal’s capital, Lisbon. Flowing in from the upper-right corner is the Tagus River. Originating in central Spain, the Tagus is the longest river on the Iberian Peninsula, stretching over 1,000 kilometers. The river flows west through Portugal, emptying into the Atlantic Ocean at Lisbon
This 20x photo of three transgenic kidneys cultured together shows colliding, branching collecting duct systems. It won 16th Place in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using confocal microscopy.
3-D movies, which require viewers to wear stereoscopic glasses, have become very popular in recent years. However, the 3-D effect produced by the glasses cannot provide perfect depth cues. Furthermore, it is not possible to move one’s head and observe that objects appear different from different angles. Now, researchers have developed a new way of generating high-resolution, full-color, 3-D videos that uses holographic technology.
Ice, wind, cold temperatures and ocean waters combined to created dramatic cloud formations over the Bering Sea in late January, 2015. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua satellite passed over the region and captured this true-color image on January 23.
