At first glance, there is not the slightest doubt: to us, the universe looks three-dimensional. But one of the most fruitful theories of theoretical physics in the last two decades is challenging this assumption. The "holographic principle” asserts that a mathematical description of the universe actually requires one fewer dimension than it seems. What we perceive as 3-D may just be the image of 2-D processes on a huge cosmic horizon.

Part of Italy’s Molise, Apulia and Campania regions are pictured in this radar composite image from Sentinel-1A. The area features two distinct types of terrain: the Apennine Mountains in the lower left and lowlands to the right. Known for its agricultural importance, the lowland area is known as the Tavoliere — a term that recalls the word tavolo meaning ‘table.’
Just as the extraordinary capabilities of 3D printing have begun to infiltrate industry and the family home, researchers have started to develop 3D printed materials that morph into new structures post production, under the influence of external stimuli, such as water or heat — hence the name, 4D printing.
Scientists have spied a vast reservoir of hot, partly molten rock beneath the supervolcano at Yellowstone National Park. It's big enough to fill the Grand Canyon 11 times over. The gigantic magma chamber is four times bigger and much deeper than the previously known chamber above it. The upper chamber was responsible for three ancient volcanic eruptions that coated much of North America in ash.
Ranger 7 took this image, the first picture of the moon by a U.S. spacecraft, on July 31, 1964 at 13:09 UT, about 17 minutes before impacting the lunar surface. The large crater at center right is the 108 km diameter Alphonsus. Above it is Ptolemaeus and below it Arzachel. The terminator is at the bottom right corner. Mare Nubium is at center and left. North is at about 11:00 at the center of the frame.

On April 25, 1990, astronauts aboard the Space Shuttle Discovery deployed the Hubble Space Telescope into Earth orbit and launched a new era of astronomical discovery. In its quarter-century in orbit, the world’s first space telescope has transformed our understanding of our solar system and beyond. Now, 25 years later, organizations around the world are joining in a celebration of this remarkable observatory.
This 40x photo features a depth-coded rendering of a transgenic mouse-ear cress (Arabidopsis thaliana) plant root tip stably expressing the nuclear histone marker H2B fused to a green fluorescent protein. It received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition.
Researchers have invented a new technology that can increase the bandwidth of WiFi systems by 10 times, using LED lights to transmit information. The technology could be integrated with existing WiFi systems to reduce bandwidth problems in crowded locations, such as airport terminals or coffee shops, and in homes where several people have multiple WiFi devices.
How is lightning initiated in thunderclouds? This is difficult to answer — how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, that cosmic rays provide suitable probes to measure electric fields within thunderclouds. The measurements, including the strength of the electric field at a certain height in the cloud, were performed with the LOFAR radio telescope.
Riedel-Kruse and his team are enabling people to interact with biological materials and perform experiments the way they interact with computers today — called interactive biotechnology. They have created three related projects that begin to define this new field. In the most far-reaching project, Riedel-Kruse created a robotic biology cloud lab capable of carrying out remote-control experiments.
Curtis writes algorithms that enable computers to solve large-scale continuous optimization problems. He is collaborating with researchers at Argonne through a five-year Early Career Award from the U.S. Department of Energy. In a three-year single-investigator project for the NSF, Curtis has developed algorithms that solve large-scale continuous optimization problems in less than a quarter of the time required by conventional methods.
Astronomers may have found "the largest individual structure ever identified by humanity." In 2004, astronomers examining a map of radiation left over from the Big Bang discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected.

According to satellite observations, lightning flashes more often over land than over the oceans. And lightning seems to happen more often closer to the equator. The NASA Earth Observatory’s Global Lightening Activity Map shows the average yearly counts of lightning flashes per square kilometer from 1995 to 2013. Areas with the largest number of lightning flashes — as many as 150 per year per square kilometer — are bright pink.

Simply declaring a region as a nature protection area is not enough, regular monitoring of its ecological condition is also necessary. New methods are being developed to monitor Europe’s nature protection areas from the air. Short laser pulses are sent to the ground, and information on the status of the habitat can be deduced from the reflected light signals using elaborate computer algorithms.
A predictive model using machine learning algorithms is able to predict with 75 percent accuracy how many asthma-related emergency room visits a hospital could expect on a given day. Twitter users who post information about their personal health online might be considered by some to be "over-sharers," but new research suggests that health-related tweets may have the potential to be helpful for hospitals.
