New technique reveals immune cell motion through variety of tissues

December 22, 2014 10:47 am | News | Comments

Neutrophils, a type of white blood cell, are the immune system’s all-terrain vehicles. The cells are recruited to fight infections or injury in any tissue or organ in the body despite differences in the cellular and biochemical composition. Researchers collaborated to devise a new technique for understanding how neutrophils move in these confined spaces.

Computational clues into the structure of a promising energy conversion catalyst

December 19, 2014 8:08 am | News | Comments

Hydrogen fuel is a promising source of clean energy that can be produced by splitting water into hydrogen and oxygen gas. The reaction is difficult but achievable with the help of a catalyst. However, current catalysts lack the efficiency required for water splitting to be commercially competitive. Recently, however, scientists have identified one such catalyst, iron-doped nickel oxide.

Sensor could improve one of nano research’s most useful microscopes

December 17, 2014 3:31 pm | by Chad Boutin, NIST | News | Comments

Spotting molecule-sized features may become both easier and more accurate with a sensor developed at NIST. With their new design, NIST scientists may have found a way to sidestep some of the problems in calibrating atomic force microscopes (AFMs). The AFM is one of the main scientific workhorses of the nano age.

Switching to spintronics

December 17, 2014 3:18 pm | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

In a development that holds promise for future magnetic memory and logic devices, researchers have successfully used an electric field to reverse the magnetization direction in a multiferroic spintronic device at room temperature. This demonstration, which runs counter to conventional scientific wisdom, points a new way towards spintronics and smaller, faster and cheaper ways of storing and processing data.

Lens-free microscope can detect cancer at the cellular level

December 17, 2014 3:07 pm | by Bill Kisliuk, Univ. of California, Los Angeles | News | Comments

Univ. of California, Los Angeles researchers have developed a lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes. The invention could lead to less expensive and more portable technology for performing common examinations of tissue, blood and other biomedical specimens.

New conversion process turns biomass “waste” into lucrative chemical products

December 17, 2014 2:58 pm | by Elizabeth K. Gardner, Purdue Univ. | Videos | Comments

A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel. A team of researchers from Purdue Univ.'s Center for Direct Catalytic Conversion of Biomass to Biofuels, or C3Bio, has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities.

A Clear Vision

December 17, 2014 9:29 am | by Paul Livingstone | Articles | Comments

Around 400 BC, Hippocrates was among the first people in recorded history to postulate the brain as the seat of sensation and intelligence. Yet only in the last 100 years have we identified, and closely studied, its key building block: the neuron. A highly specialized cell found in all but the simplest animals, like sponges, the neuron is one of the keys to understanding the brain.

Rover finds methane spikes on Mars

December 17, 2014 8:32 am | by Associated Press, Marcia Dunn | News | Comments

NASA's Mars rover, Curiosity, has detected spikes of methane in the planet's atmosphere. That suggests something is producing or venting the scientifically tantalizing gas, but no one knows what. Most of Earth's atmospheric methane comes from animal and plant life, and the environment itself. So the Martian methane raises the question of past or present microbial life.

Big data analysis reveals gene sharing in mice

December 17, 2014 8:01 am | by Mike Williams, Rice Univ. | News | Comments

Rice Univ. scientists have detected at least three instances of cross-species mating that likely influenced the evolutionary paths of “old world” mice, two in recent times and one in the distant past. The researchers think these instances of introgressive hybridization are only the first of many needles waiting to be found in a very large genetic haystack.

Life on an aquaplanet

December 17, 2014 7:43 am | by Jennifer Chu, MIT News Office | News | Comments

Nearly 2,000 planets beyond our solar system have been identified to date. Whether any of these exoplanets are hospitable to life depends on a number of criteria. Among these, scientists have thought, is a planet’s obliquity—the angle of its axis relative to its orbit around a star.
