VLT Reveals Alignment of Quasars Across Billions of Light-Years

Mysterious Alignment of Quasars

Using data from ESO’s Very Large Telescope, astronomers have discovered alignments between supermassive black hole axes separated by billions of light-years. New observations with ESO’s Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the […]

Quantum-Dot Technology Ready to Improve LCD TVs

Quantum-Dot Technology Improves TV Color Gamut

New quantum-dot technology is set to make LCD TVs more colorful and energy-efficient, all while costing less than OLED displays and other color gamut boosting methods. If LCD TVs start getting much more colorful — and energy-efficient — in the next few years, it will probably be thanks to MIT spinout QD Vision, a pioneer […]

Discovery Hints at New Strategy for Fighting HIV

New Strategy for Fighting HIV

Researchers from Yale University have discovered an immune system reaction that may open a new avenue in the fight against HIV. The discovery of the innate immunity system’s role in mobilizing the body’s defenses against invading microorganisms has been long studied at Yale. Now in the November 17 issue of the journal Nature Immunology, Yale […]

Martian Rock Provides Clues to Wet History

Textures in Rock Provide Evidence about Wet Environmental Conditions on Ancient Mars

This close-up image of a Martian rock has provided scientists with evidence about wet environmental conditions in the ancient past on Mars. This close-up view of a target rock called “Last Chance” was acquired by the microscopic imager on the arm of NASA’s Mars Exploration Rover Opportunity on March 3, 2004, during the 39th Martian […]

Scientists Develop a Nanolamp with a Lightning-Fast Switch

A Nanolamp with Lightning-Fast Switch

Scientists have developed a light source which converts an electrical voltage pulse into a light pulse by means of a single molecule, possibly serving as a prototype for nano-components that convert electrical into optical signals with gigahertz frequencies. Information is processed and transmitted by ever-smaller components, sometimes with electrons and sometimes with light. Scientists at […]

Study Shows Calorie-Restricting Diets Slow Aging

Calorie-Restricting Diets Slow Aging

Neuroscientists show that calorie-reduced diets stop the normal rise and fall in activity levels of close to 900 different genes linked to aging and memory formation in mice. The adage ‘you are what you eat’ has been around for years. Now, important new research provides another reason to be careful with your calories. In a […]

New Nanoparticles Simultaneously Perform MRI and Fluorescent Imaging

Nanoparticles That Enable Both MRI and Fluorescent Imaging

Scientists at MIT have developed new nanoparticles that simultaneously enable both MRI and fluorescent imaging in living animals, helping scientists to track specific molecules produced in the body, monitor a tumor’s environment, or determine whether drugs have successfully reached their targets. In a paper appearing in the November 18 issue of Nature Communications, the researchers […]

Yale Researchers Develop Method to Attack Cancer at Its Source

Yale Develops Method to Attack Cancer at Its Genetic Source

A team of researchers at Yale University has developed a therapeutic molecule that both targets the acidic microenvironments of tumors and penetrates cells to deliver a therapeutic cargo. MicroRNAs may be tiny — as few as 20 genetic letters, compared to 3 billion in the DNA of a human — but they play a major […]

Cassini Views Saturn’s Uppermost Cloud Layers

Cassini Views Saturn's Clouds

This newly released image of Saturn’s uppermost cloud layers was taken with the Cassini spacecraft narrow-angle camera on August 23, 2014. Nature is an artist, and this time she seems to have let her paints swirl together a bit. What the viewer might perceive to be Saturn’s surface is really just the tops of its […]

New NASA Animation Follows Long, Strange Trip of Asteroid Bennu

Asteroid Bennu

This new six minute animated video (below) details NASA’s OSIRIS-REx mission, Asteroid Bennu, and the formation of our solar system. Born from the rubble of a violent collision, hurled through space for millions of years and dismembered by the gravity of planets, asteroid Bennu had a tough life in a rough neighborhood: the early solar […]

NASA Model Provides a New Look at How Carbon Dioxide in the Atmosphere Travels

A Year in the Life of Earth's CO2

This three minute video shows how carbon dioxide in the atmosphere travels around the globe over a 12 month period. An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds […]

Scientists Synthesize an Entirely New Form of Silicon

Scientists Synthesize a New Form of Silicon

Using a novel high-pressure precursor process, scientists from the Carnegie Institution for Science have synthesized an entirely new form of silicon. Washington, D.C. — Silicon is the second most-abundant element in the earth’s crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices—carbon is to biology as silicon is […]

First Direct Evidence That Intergalactic “Wind” is Stripping Galaxies of Star-Forming Gas

Intergalactic Wind is Stripping Galaxies of Gas

A newly published study provides the first direct evidence that an intergalactic “wind” is stripping galaxies of star-forming gas as they fall into clusters of galaxies, helping explain why galaxies found in clusters are known to have relatively little gas and less star formation when compared to non-cluster or “field” galaxies. Toronto, Ontario – Astronomers […]

Engineered Bacteria Store Memories of Chemical Exposure

Engineered Bacteria Can Store Memories of Chemical Exposure

New research from MIT reveals that engineered E. coli can store long-term memories of chemical exposure and other events in their DNA. MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications […]

The Future of Astrophysical Neutrino Measurements

The Future of Neutrino Cosmology

An international team of scientists has published an extensive report on the future of astrophysical neutrino measurements, discussing how facilities that measure the microwave background will in the next decade also enable scientists to study the nature of neutrinos, and lead to fundamental insights into the basic laws of nature. One of the most remarkable […]
