Scientists Discover Important Mechanism for Muscle Building

Researchers identify a key mechanism to how basic muscle architecture is built, finding that mechanical tension is the essential trigger. Skeletal muscles are built from small contractile units, the sarcomeres. Many of these sarcomeres are connected in a well-ordered series to form myofibrils that span from one muscle end to the other. Contractions of these […]

New Study Resolves a Decades-Old Paradox between Thermal History Models and Estimates of Mercury’s Contraction

A newly published study from the Carnegie Institute resolves a decades-old paradox between thermal history models and estimates of Mercury’s contraction, showing that Mercury contracted substantially more than the old estimates. Washington, D.C. — New global imaging and topographic data from MESSENGER* show that the innermost planet has contracted far more than previous estimates. The […]

Cassini Uses “Pi Transfer” to Create Mosaic Image of Saturn

Using a technique known as a “pi transfer,” – a technique that uses the gravity of Saturn’s moon Titan to alter the orbit of the Cassini spacecraft – Cassini created this image of Saturn and its rings from a mosaic of 36 images. Surely one of the most gorgeous sights the solar system has to […]

Hubble Views Spiral Galaxy NGC 5793

This newly released Hubble image shows spiral galaxy NGC 5793, which is located 150 million light-years away. This new Hubble image is centered on NGC 5793, a spiral galaxy over 150 million light-years away in the constellation of Libra. This galaxy has two particularly striking features: a beautiful dust lane and an intensely bright center […]

Naturally Occurring Molecule Enhances Defense Mechanisms Against Neurodegenerative Diseases

Scientists have discovered that a substance called N-acetylglucosamine has the ability to enhance defense mechanisms against neurodegenerative diseases, clear toxic protein aggregates and extend life span. Scientists at the Max Planck Institute for Biology of Aging in Cologne have found that a naturally occurring molecule has the ability to enhance defense mechanisms against neurodegenerative diseases. […]

Scientists Simulate the Extreme Conditions of the Fluid Reservoirs in the Crust of Europa

Researchers have developed an experiment to help explain and recreate the extreme conditions of the fluid reservoirs in the crust of Europa. Water, salts and gases dissolved in the huge ocean that scientists believe could exist below Europa´s icy crust can rise to the surface generating the enigmatic geological formations associated to red-tinged materials that […]

Researchers Model the Workings of an X-ray Binary Star

Using ten years’ worth of optical, infrared and X-ray data on LMC X-3, astronomers developed a model that can successfully explain the workings of an X-ray binary star. The bright X-ray source known as LMC X-3 resides in the Large Magellanic Cloud, the dwarf galaxy that is the Milky Way’s nearest neighbor. Two decades ago […]

Researchers Discover an Efficient Way of Slowing the Rotation of Molecular Ions

An international team of researchers has discovered an efficient and versatile way of slowing the rotation of molecular ions, opening up new possibilities for laboratory-based astrochemistry. Chemical reactions taking place in outer space can now be more easily studied on Earth. An international team of researchers from the University of Aarhus in Denmark and the […]

Astronomers View Dense Disk and Bright Funnel at the Center of the Circinus Galaxy

An international team of astronomers has viewed a dense disk and a bright funnel at the center of the Circinus galaxy. A research team led by Konrad Tristram from the Max Planck Institute for Radio Astronomy in Bonn, Germany, obtained the most detailed view so far of the warm dust in the environment of a […]

Hubble Views Asteroid P/2013 R3 Mysteriously Disintegrating

Hubble views the disintegration of asteroid P/2013 R3, providing detailed observations that pinpoint the process responsible. The NASA/ESA Hubble Space Telescope has photographed the never-before-seen break-up of an asteroid, which has fragmented into as many as ten smaller pieces. Although fragile comet nuclei have been seen to fall apart as they approach the Sun, nothing […]

Habitable Zones Near Red Dwarf Stars Smaller than Previously Thought

A newly published study reveals that habitable zones near red dwarf stars may be smaller than previously thought. The researchers believe that the exoplanets orbiting the red dwarfs may be mostly covered by icy crusts, save for somewhat lobster-shaped oceans on their day sides. Alien planets circling the most common stars in the universe may […]

New Study Shows that IRX3 Is Likely the “Fat Gene”

A new study shows that the IRX3 gene controls body mass and regulates body composition, and appears to be the functional obesity gene. Mutations within the gene FTO have been implicated as the strongest genetic determinant of obesity risk in humans, but the mechanism behind this link remained unknown. Now, an international team of scientists […]
