Comet 2013 A1 to Make a Very Close Flyby of Mars

Comet 2013 A1 Will Make a Very Close Approach to Mars

Scientists have projected that comet 2013 A1 will make a very close approach to Mars in October 2014, possibly passing as close as 31,000 miles (50,000 kilometers) from the Red Planet’s surface. The latest trajectory of comet 2013 A1 (Siding Spring) generated by the Near-Earth Object Program Office at NASA’s Jet Propulsion Laboratory in Pasadena, […]

New Data Suggests a Chemical Exchange Between Europa’s Ocean and Surface

Evidence that Salty Water Beneath the Surface of Europa Actually Makes its Way to the Surface

Using data from the W. M. Keck Observatory, researchers have the best evidence yet that salty water from the liquid ocean beneath Europa’s frozen exterior actually makes its way to the surface. Kamuela, Hawaii — With data collected from the mighty W. M. Keck Observatory, California Institute of Technology (Caltech) astronomer Mike Brown — known […]

Gravitational Lensing Gives Hubble Image of Abell 68 a Unique Look

Hubble Views Abell 68

This new Hubble Space Telescope image of Abell 68 is enhanced by gravitational lensing, showing swarms of galaxies that each have billions of stars and vast amounts of dark matter. The NASA/ESA Hubble Space Telescope is one of the most powerful available to astronomers, but sometimes it too needs a helping hand. This comes in […]

Study Finds a New Target in Childhood Brain Cancer

Researchers Identify a New Target in Childhood Brain Cancer

In a newly published study, an international team of scientists has identified a molecular pathway that appears to be essential for the growth and spread of medulloblastoma, the most common malignant brain tumor in children. In their report in the February 28 issue of Cell, they show that blocking this pathway—which involves interactions between tumor […]

Nanogels Provide a New Way to Attack Lupus

Nanogels Offer a New Way to Treat Lupus

In a new study, Yale researchers used biodegradable nanoparticles called nanogels to deliver relatively low drug doses to mice with lupus, increasing the median survival time of lupus-prone mice and mice that already had severe kidney damage. Scientists at Yale University have designed and tested a drug delivery system that shows early promise for improved […]

Boron Nitride Nanotubes Channel Osmotic Power

Nanotubes Channel Osmotic Power

Using boron nitride nanotubes, researchers have discovered a new method for harnessing energy from the salinity difference between fresh water and salt water. The salinity difference between fresh water and salt water could be a source of renewable energy. However, power yields from existing techniques are not high enough to make them viable. A solution […]
