Metallic glass nanorods, shown here, are fabricated by sputtering, using a self-shadowing mechanism. A vast range of chemical compositions can be realized with this method, over large macroscopic areas.

New Ebola Cases Are Declining: Why That's Bad News For A Cure
Dr. Francis Kateh receives an experimental Ebola vaccine as part of a
clinical trial that began in Liberia in February 2015. With the number
of new cases falling, some experts say it may be too late to gather
useful scientific data about potential Ebola drugs and vaccines.

Researchers May Have Solved Origin-of-Life Conundrum
The crash of meteors on early Earth likely generated hydrogen cyanide,
which could have kick-started the production of biomolecules needed to
make the first cells.

Scientists Confirm 'Greenhouse' Effect of Human's CO2
Earth's atmosphere, here in light blue, acts like the window on a glass greenhouse. Some gases - such as CO2 - trap certain wavelengths of light (here shown in red). That trapped energy, or heat, warms our planet.

How to Pick Up Messages After They're Gone
Today, astronomers read the history of the universe by looking at the light emitted by hot, distance objects. Sometimes, however, those light sources give out - and their light disappears. Good news: A new technique might be able to still read the information that had been carried in that long-gone light.

Foraging Metamaterials: Labs Craft Invisibility Cloaks, Perfect Lenses and Nanostructures
Credit: Les Todd, Duke University Photography
An invisibility
cloak developed by David Smith's laboratory at Duke University. Placing
an object in the center makes it invisible to microwave radiation. The
cloaking material splits the oncoming microwaves, guiding them around
the object and recombining them on the other side. Since the microwaves
do not interact with the cloaked object, an observer on the right or
left of the object would not notice it was hidden.

'Smart' Windows Could Save Energy
At temperatures above 32 degrees C (90 degrees F), a new "smart window" (left) blocked some of the light streaming into a box from a sun lamp. That kept the box cooler than the one at right, which had a more conventional window.
