New Debugging Method Finds 23 Undetected Security Flaws in Popular Web Applications

New Debugging Method Finds Undetected Security Flaws in Popular Web Applications

A new debugging system found 23 previously undiagnosed security flaws in 50 popular Web applications, and it took no more than 64 seconds to analyze any given program. By exploiting some peculiarities of the popular Web programming framework Ruby on Rails, MIT researchers have developed a system that can quickly comb through tens of thousands […]

New Horizons Shows Pluto’s Haze Varies in Brightness

New Research Shows Pluto’s Haze Varies in Brightness

New images from NASA’s New Horizons Spacecraft reveal that Pluto’s haze varies in brightness. Scientists on NASA’s New Horizons mission team are learning more about the structure and behavior of Pluto’s complex atmosphere by discovering new attributes of its extensive haze layers. The hazes were first discovered by New Horizons in July, as the spacecraft […]

Cassini Y-Shaped Discontinuity on Enceladus

Cassini Spacecraft Views Enceladus' South Pole

NASA’s Cassini Spacecraft views a Y-shaped discontinuity on Enceladus’ south pole. A sinuous feature snakes northward from Enceladus’ south pole like a giant tentacle. This feature, which stretches from the terminator near center, toward upper left, is actually tectonic in nature, created by stresses in Enceladus’ icy shell. Geologists call features like these on Enceladus […]

Zipf’s Law from Scale-free Geometry – Like Galaxies, Like Cities

Zipf's Law from Scale-Free Geometry

Abstract: The spatial distribution of people exhibits clustering across a wide range of scales, from household (∼10−2 km) to continental (∼104 km) scales. Empirical data indicates simple power-law scalings for the size distribution of cities (known as Zipf’s law) and the population density fluctuations as a function of scale. Using techniques from random field theory […]

Harvard Research Shows For Life Expectancy, Money Matters

Study Shows Money Matters For Life Expectancy

New research from Harvard University shows that being poor in the United States is hazardous to your health, revealing that the average life expectancy of the lowest-income classes in America is now equal to that in Sudan or Pakistan. A Harvard analysis of 1.4 billion Internal Revenue Service records on income and life expectancy that […]

New Spitzer Image: A Space Spider Watches Over Young Stars

New Spitzer Image of the Spider Nebula

This new infrared image from NASA’s Spitzer Space Telescope and the Two Micron All Sky Survey shows IC 417, which is about 10,000 light-years away. A nebula known as “the Spider” glows fluorescent green in an infrared image from NASA’s Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS). The Spider, officially named […]

New Discovery Challenges Dark Matter, Stellar Acceleration Models

New Hypervelocity Binary Star Challenges Dark Matter, Stellar Acceleration Models

Astronomers have discovered a hypervelocity binary star that challenges dark matter and stellar acceleration models. A team of astronomers at the Friedrich Alexander University led by Péter Németh has discovered a binary star moving nearly at the escape velocity of our galaxy. There are about two dozen so-called hypervelocity stars known to be escaping the […]

Stars Strip Away the Atmosphere of Super-Earths

Stars Strip Away the Atmosphere of Nearby Super-Earths

Even a super-Earth can fly too close to the sun, according to a new study from Yale University. An international team of astronomers has found a new category of planets beyond our solar system whose atmosphere has been stripped bare by the radiation from their own sun. The findings will appear in the journal Nature […]

MIT Researchers Create Perfect Nanoscrolls from Graphene Oxide

Researchers Create Perfect Nanoscrolls

Using both low- and high-frequency ultrasonic techniques, scientists have fabricated nanoscrolls made from graphene oxide flakes. Water filters of the future may be made from billions of tiny, graphene-based nanoscrolls. Each scroll, made by rolling up a single, atom-thick layer of graphene, could be tailored to trap specific molecules and pollutants in its tightly wound […]

Children of Older Mothers Are Healthier, Taller and Obtain More Education

Children of Older Mothers Do Better

New research shows that the benefits associated with being born in a later year outweigh the biological risks associated with being born to an older mother. Children of older mothers are healthier, taller and obtain more education than the children of younger mothers. The reason is that in industrialized countries educational opportunities are increasing, and […]

APEX Explores the Onset of Pulsation-Driven Winds in Giant Stars

Exploring the Onset of Pulsation-Driven Winds in Giant Stars

Astronomers from the Harvard-Smithsonian Center for Astrophysics used the APEX submillimeter telescope to study the velocity of the CO gas in the wind of the giant star EU Del to help constrain the mechanism responsible for driving its wind. Nearly all stars have winds. The Sun’s wind, which originates from its hot outer layer (corona), […]

New Cassini View of Saturn’s Rings

New Image of Saturn's Rings

Cassini gets a closer look at Saturn’s rings. It’s difficult to get a sense of scale when viewing Saturn’s rings, but the Cassini Division (seen here between the bright B ring and dimmer A ring) is almost as wide as the planet Mercury. The 2,980-mile-wide (4,800-kilometer-wide) division in Saturn’s rings is thought to be caused […]

Astronomers Discover a 17 Billion Solar-Mass Black Hole in an Unlikely Place

A 17 Billion Solar-Mass Black Hole Discovered

Using the Hubble Space Telescope and the Gemini Telescope in Hawaii, a team of astronomers has uncovered one of the biggest supermassive black holes in an unlikely place: the center of a galaxy that lies in a quiet backwater of the Universe. Until now, the biggest supermassive black holes — those having more than 10 […]

Hubble Image of the Week – Dwarf Galaxy Leo A

Hubble Image of Dwarf Galaxy Leo A

This newly released Hubble image shows dwarf galaxy Leo A, which is located roughly 2.5 million light-years from Earth. At first glance this NASA/ESA Hubble Space Telescope image seems to show an array of different cosmic objects, but the speckling of stars shown here actually forms a single body — a nearby dwarf galaxy known […]

Newly Released Cassini Image – Saturn Askew

New Image of Saturn from Cassini

Another great image of Saturn from NASA’s Cassini Spacecraft. As a convention for public release, Cassini images of Saturn are generally oriented so that Saturn appears north up, but the spacecraft views the planet and its expansive rings from all sorts of angles. Here, a half-lit Saturn sits askew as tiny Dione (698 miles or […]
