Cyclone Rusty has been moving very slow over the last two days on its approach to landfall near Port Hedland in Western Australia, and NASA satellites have observed the storm's increase in power. NASA's TRMM and Aqua satellites provided rainfall, cloud height and temperature data that showed Cyclone Rusty intensified as it neared land.

Rusty is a large storm and its slow movement means more rainfall, more flooding potential, increasingly rough surf and a longer period of tropical-storm-force winds along the Pilbara coast.

Firefighters put their lives on the line in some of the most dangerous conditions on Earth. One of their greatest challenges, however, is seeing through thick veils of smoke and walls of flame to find people in need of rescue. A team of Italian researchers has developed a new imaging technique that uses infrared (IR) digital holography to peer through chaotic conflagrations and capture potentially lifesaving and otherwise hidden details.

Tropical Cyclone Rusty formed on Feb. 24 and has already caused warnings up for the residents of northwestern West Australia, including Port Hedland. NASA's Terra satellite saw that outer bands of this quick-forming tropical cyclone were already affecting land.

Ex-cyclone Haruna is expected to dissipate in the Southern Indian Ocean under increasing wind shear in the next day or two. Infrared imagery from a NASA satellite shows that Haruna is being blown apart several hundred miles away from La Reunion Island.

The eighteenth tropical cyclone of the Southern Indian Ocean season formed over the weekend of Feb. 23-24 along with Cyclone Rusty as Cyclone Haruna crossed southern Madagascar. NASA's Aqua satellite measured Tropical Storm 18S' cloud top temperatures and saw powerful thunderstorms around the storm's core.

Cyclone Rusty is nearing a landfall in northwestern West Australia, while Tropical Storm 18S is headed in a similar direction.

Even dying stars could host planets with life - and if such life exists, we might be able to detect it within the next decade. This encouraging result comes from a new theoretical study of Earth-like planets orbiting white dwarf stars. Researchers found that we could detect oxygen in the atmosphere of a white dwarf's planet much more easily than for an Earth-like planet orbiting a Sun-like star.

(Edmonton) Researchers from the University of Alberta are helping children with Down syndrome who stutter find their voice and speak with ease.

Stuttering is a common problem that affects almost half of all children with Down syndrome, yet despite the scope of the problem, little research exists about preferred treatment options—or even whether to treat at all. Researchers with the U of A's Institute for Stuttering Treatment and Research (ISTAR) point to a new case study that shows fluency shaping can indeed improve a child's speech.

NASA's Aqua satellite passed over Cyclone Haruna after it made landfall in southwestern Madagascar.

Haruna's center made landfall near Manombo, Madagascar around 0600 UTC (1 a.m. EST/U.S.) The METEO-7 satellite captured a visible image of Haruna at the time of landfall and showed that its eye had already become cloud-filled.

Washington, D.C.—Solar geoengineering is a proposed approach to reduce the effects of climate change due to greenhouse gasses by deflecting some of the sun's incoming radiation. This type of proposed solution carries with it a number of uncertainties, however, including geopolitical questions about who would be in charge of the activity and its goals.

Researchers from North Carolina State University have developed a way to melt or "weld" specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to stronger, more resilient nanofibers and materials.

Voracious absences at the center of galaxies, black holes shape the growth and death of the stars around them through their powerful gravitational pull and explosive ejections of energy.

"Over its lifetime, a black hole can release more energy than all the stars in a galaxy combined," said Roger Blandford, director of the Kavli Institute for Particle Astrophysics and Cosmology and a member of the U.S. National Academy of Science. "Black holes have a major impact on the formation of galaxies and the environmental growth and evolution of those galaxies."

CAMBRIDGE, MA -- By analyzing Mercury's rocky surface, scientists have been able to partially reconstruct the planet's history over billions of years. Now, drawing upon the chemical composition of rock features on the planet's surface, scientists at MIT have proposed that Mercury may have harbored a large, roiling ocean of magma very early in its history, shortly after its formation about 4.5 billion years ago.

Unlike comets, asteroids are not characterised by exhibiting a trail, but there are now ten exceptions. Spanish researchers have observed one of these rare asteroids from the Gran Telescopio Canarias (Spain) and have discovered that something happened around the 1st July 2011 causing its trail to appear: maybe internal rupture or collision with another asteroid.

Processing a prescription through an electronic ordering system can halve the likelihood of a drug error, and avert more than 17 million such incidents in US hospitals in one year alone, indicates research published online in the Journal of the American Medical Informatics Association.

And if much more widely adopted than at present, the system has the potential to cut out 50 million drug errors a year, calculate the researchers.

The US Institute of Medicine estimates that, on average, at least one mistake will be made with a hospital patient's medication every day.

COLUMBIA, Mo. – After retirement, pensions provide consistent income to aging individuals. Although the details of pension eligibility and implementation vary by country, receiving pensions can represent a new life stage for individuals. Now, a University of Missouri researcher has studied how older men and women view their health before and after receiving fixed incomes. South African men and women in the study viewed their health more positively when they began receiving their pensions, but the heightened sense of well-being faded over time.
