Solid-state proteins maximize the intensity of fluorescent-protein-based lasers
The same research team that developed the first laser based on a living cell has shown that use of fluorescent proteins in a solid form rather than in solution greatly increases the intensity of light produced, an accomplishment that takes advantage of natural protein structures surrounding the light-emitting portions of the protein molecules.

Biomimetic dew harvesters
Insects are full of marvels -- and this is certainly the case with a beetle from the Tenebrionind family, found in the extreme conditions of the Namib desert. Now, a team of scientists has demonstrated that such insects can collect dew on their backs -- and not just fog as previously thought. This is made possible by the wax nanostructure on the surface of the beetle's elytra. These findings were recently published in EPJ E.

High photosensitivity 2-D-few-layered molybdenum diselenide phototransistors
Researchers at Toyohashi University of Technology, Japan have fabricated High photosensitivity back-gated field-effect phototransistors made of only 20 nanometer thick molybdenum diselenide crystals by facile mechanical cleavage and transfer of MoSe2 flakes onto a silicon wafers for next generation for photodetector applications.

New technique allows low-cost creation of 3-D nanostructures
Researchers have developed a new lithography technique that uses nanoscale spheres to create 3-D structures with biomedical, electronic and photonic applications. The new technique is less expensive than conventional methods and does not rely on stacking two-dimensional patterns to create 3-D structures.

Finding the Achilles' heel of GaN-based LEDs in harsh radiation environments
Toyohashi Tech researchers in Japan have discovered that proton irradiation of gallium nitride causes more damage in p-type material than n- doped layers. This unexpected finding is important for the application of GaN-based devices in extreme environments.

Light propagation in solar cells made visible
How can light which has been captured in a solar cell be examined in experiments? Jülich scientists have succeeded in looking directly at light propagation within a solar cell by using a trick. The photovoltaics researchers are working on periodic nanostructures that efficiently capture a portion of sunlight which is normally only poorly absorbed.

When noise gets electrons moving
Studying the motion of electrons in a disordered environment is no simple task. Often, understanding such effects requires a quantum simulator designed to expose them in a different physical setup. This was precisely the approach adopted by Denis Makarov and Leonid Kon'kov in a new study published in EPJ B. They relied on a simulator of electronic motion subjected to noise stemming from a flux of sound waves.

Electron pairs on demand
Physicists from Leibniz University Hannover and from the Physikalisch-Technische Bundesanstalt have demonstrated for the first time the on-demand emission of electron pairs from a semiconductor quantum dot and verified their subsequent splitting into two separate conductors. Their results -- which could be important for quantum computers and quantum cryptography -- have been published in the current online issue of Nature Nanotechnology.

Geckos are sticky without effort
Scientists have studied a variety of features in geckos such as the adhesive toe pads on the underside of the feet with which geckos attach to surfaces with remarkable strength. UC Riverside biologists have now conducted experiments in the lab on live and dead geckos that show, for the first time, that dead geckos can adhere to surfaces with the same strength as living geckos. The research could have applications in the field of robotics.

Colorful nano-guides to the liver
Jena scientists have been successful in producing highly specific nanoparticles. Depending on the bound dye the particles are guided to the liver or to the kidney and deliver their payload of active ingredients directly to the targeted tissue. Moreover, the dyes enable the tracking of the transport processes by intravital microscopy or, in a non-invasive way, by multi spectral optoacoustic tomography. The reduction of cholesterol production induced by siRNA served as the proof-of-principle for the developed method.

Wireless nanorod-nanotube film enables light stimulation of blind retina
Scientists have developed a new light-sensitive film that could one day form the basis of a prosthetic retina to help people suffering from visual impairment. Hebrew University researchers collaborated with Tel Aviv University and Newcastle University colleagues to develop a novel device that absorbs light and stimulates neurons without using wires or external power. Combining semiconductor nanorods and carbon nanotubes, it could potentially form part of a future prosthetic device that replaces damaged retinal cells.

'Smart dust' technology could reshape space telescopes
Scientists at Rochester Institute of Technology and the NASA Jet Propulsion Laboratory are exploring a new type of space telescope with an aperture made of swarms of particles released from a canister and controlled by a laser. These floating lenses would be larger, cheaper and lighter than apertures on conventional space-based imaging systems like NASA's Hubble and James Webb space telescope.
