Label-free biosensors are relatively new in biochemical and pharmaceutical laboratories, and have made work much easier. The sensors enable researchers to detect low concentrations of biologically significant molecular substances (RNA, DNA, proteins, including antibodies and antigens, viruses and bacteria) and study their chemical properties.

Connections, or synapses, between neurons are inspiring scientists to create artificial versions that could lead to smarter electronics.

A low pressure system in the Pacific Ocean south of Alaska has moved far enough eastward that it is bringing rain and strong winds to the Pacific Northwest where the OLYMPEX field campaign is under way. NASA's RapidScat instrument analyzed those strong coastal winds from space.

During a noon EST media teleconference on November 13, NASA and university scientists will discuss new insights, tools and agency research into key carbon and climate change questions, as the agency ramps up its efforts to understand how Earth’s ocean, forest, and land ecosystems absorb nearly half of emitted carbon dioxide today.

Mercaptans or thiols are a special class of organic compounds that contains sulfur functional group, RSH. Various sulfur compounds are highly demanded in the formation of new materials in photonics, optics, pharmaceutical industry, organic chemistry, and nanotechnology.

Figure 1: [Left] Typical plasma crystal with a self-ordered, hexagonal arrangement of dust particles indicated by the bright white spots. [Middle] Made to order square pattern formed in an imposed dust crystalline-like structure. [Right] A typical dusty plasma illuminated by a green laser in the MDPX experiment at Auburn University.
Figure 2: Breakup of the dust grid structure is observed as the background neutral pressure is increased from low to high pressure. Each image is a sum of over 100 individual picture frames to reveal the motion of the dust particle trajectories. With increasing pressure the particles "unlock" from the grid generated crystal and begin to flow, first from lattice site to lattice site, and then forming a swirling pattern at high pressure. The yellow boxes show close-ups of the observed particle pattern at different pressures for the area highlighted in the left figure.

An artist's rendering shows the layers of a new, onion-like nanoparticle whose specially crafted layers enable it to efficiently convert invisible near-infrared light to higher energy blue and UV light.
