Light-emitting diodes (LEDs) at infrared wavelengths are the magic
behind
such things as night vision and optical communications. Cornell
University researchers
have advanced the process of making such LEDs cheaper and easier to
fabricate,
which could lead to ultrathin LEDs painted onto silicon to replace
computer
wiring with light waves.

Cornell University researchers have demonstrated a new strategy for making energy-efficient, reliable nonvolatile magnetic memory devices, which retain information without electric power. The researchers use a physical phenomenon called the spin Hall effect, that turns out to be useful for memory applications because it can switch magnetic poles back and forth.

By measuring how strongly electrons are bound together to form Cooper pairs in an iron-based superconductor, scientists provide direct evidence supporting theories in which magnetism holds the key to this material’s ability to carry current with no resistance. This research strengthens confidence that this type of theory may one day be used to identify or design new materials with improved properties.

Cornell
materials scientists have developed an inexpensive, environmentally
friendly way of synthesizing oxide crystal sheets, just nanometers
thick, which have useful properties for electronics and alternative
energy applications. Unlike typical oxides, these sheets are conducting,
and could be ideal for use in thermoelectric devices to convert waste
heat into power.

For catalysts in fuel cells and electrodes in batteries, engineers would like to manufacture metal films that are porous, to make more surface area available for chemical reactions, and highly conductive, to carry off the electricity. The latter has been a frustrating challenge. But Cornell University chemists have now developed a way to make porous metal films with up to 1,000 times the electrical conductivity offered by previous methods.

Therapeutic proteins, which provide cutting-edge treatments of cancer, diabetes, and countless other diseases, are among today's most widely consumed biopharmaceuticals. By introducing bottom-up carbohydrate engineering into common bacterial cells, Cornell University researchers have discovered a way to make these drugs cheaper and safer.

Two Cornell professors will combine their inventions to develop a handheld pathogen detector that will give health care workers in the developing world speedy results to identify in the field such pathogens as tuberculosis, chlamydia, gonorrhea, and HIV.

The eventual failure of metals can often be blamed on breaks, or voids, in the material's atomic lattice. They're at first invisible, but once enough of them link up, the metal eventually splits apart. Cornell University engineers, trying to better understand this process, have discovered that nanoscale voids behave differently than the larger ones that are hundreds of thousands of atoms in scale, studied through traditional physics.

The human genome contains some three billion base pairs that are tightly compacted into the nucleus of each cell. If a DNA strand were the thickness of a human hair, the entire human genome would be crammed into a space the size of a softball, but if it were unraveled and all the strands lined up, they would stretch from Ithaca, N.Y., to Boston. A Cornell University study teases out how cells undergo transcription.
