NASA’s
next flagship mission, the James Webb Space Telescope, will carry the
largest primary mirror ever deployed in space. Researchers has borrowed a
page from its segmented mirror design to create a similar example just a
half-inch in diameter. Strangely, the tiny mirror may one day become
the standard for future space telescopes.

There's nothing like a new pair of eyeglasses to bring fine details into sharp relief. For scientists who study the large molecules of life from proteins to DNA, the equivalent of new lenses have come in the form of an advanced method for analyzing data from X-ray crystallography experiments. The findings could lead to new understanding of the molecules that drive processes in biology, medical diagnostics, nanotechnology, and other fields.

Sensors that work flawlessly in laboratory settings may stumble when it comes to performing in real-world conditions, according to researchers at Oak Ridge National Laboratory. These shortcomings are important as they relate to safeguarding the nation's food and water supplies.

In
quantum physics physical processes in condensed matter and other
many-body systems can often be described with quasiparticles. For the
first time, a team of physicists in Austiri has succeeded in
experimentally realizing a new quasiparticle— a repulsive polaron—in an
ultracold quantum gas.

The
contention of a major but controversial new theory to explain
nanocrystal growth is that nanoparticles can act as “artificial atoms,”
forming molecular-type building blocks that can assemble into complex
structures. The conclusion is based on recent observations of growing
nanorods made by Lawrence Berkeley National Laoratory researchers using
transmission electron microscopy and advanced liquid cell handling
techniques.

Researchers in Germany have for years been studying fire beetles of the genus <i>Melanophila</i>
and their sophisticated infrared sensors, which these pyrophilous
insects use to detect forest fires. They have unraveled the functional
principle of this photomechanical sensor and have started to work on a
technical reconstruction.

In
the course of its evolution, the architecture of the mouse brain may
have barely changed. In fact, researchers point to it as a “living
fossil” of brain development, preserving our ancestors’ neuronal
circuits’ architecture. Comparative analysis now shows where those
changes occurred after the extinction of dinosaurs and the growth of
mammals.

Dark
matter accounts for at least 80% of the matter in the universe. No one
knows what it is, but most scientists would bet on weakly interacting
massive particles, or WIMPs. LUX, the Large Underground Xenon detector
at the Sanford Underground Research Facility nearly a mile below the
Black Hills of South Dakota, holds 350 kg of liquid xenon and is a trap
set for dark-matter WIMPs.

Getting a shot at the doctor's office may become less painful in the not-too-distant future. Massachusetts Institute of Technology researchers have engineered a device that delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. The device can be programmed to deliver a range of doses to various depths—an improvement over similar jet-injection systems that are now commercially available.

A research group from Stony Brook University reports the development and demonstration of a novel probe for atomic quantum matter. Their work describes a proof-of-principle experiment on the diffraction of atomic de Broglie waves from a strongly correlated gas of atoms held in an optical lattice.
