In nature, proteins sweep up nanoparticles

...ense aggregates. Such tightly packed metal sulfide formations are not new to scientists, but they do beg a question that remains unanswered: Why do the nanoparticles group together" Something so small should disperse throughout the mine. Instead, the metal nanoparticles form blobs that measure several microns i...

New designer lipid-like peptide with lipid nanostructures for drug delivery systems

...olt, Peter Laggner and Shuguang Zhang reported the formations of dynamic nanostructures of lipid-like peptides that are like two-headed Janus, both water-loving and water-hating, which represent a new class of designer materials using common amino acids, the same basic molecules from meat, beans and fruits. Th...

Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

...rground in a high-pressure, liquid form. Sandstone formations common in Texas and some other states are already being considered nationally for this type of storage. Colleagues at the Jackson School’s Bureau of Economic Geology will also study this storage option at the bureau’s Gulf Coast Carbon Center. The...

Faster, more accurate tuberculosis test developed

...tic tangles or coils and these characteristic cord formations can be seen microscopically in liquid medium; and (3) the ability to incorporate drugs permits rapid and direct drug-susceptibility testing at the same time as the detection of bacterial growth. Over 5,000 people die of TB every day worldwide and t...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...US Air Force) to test whether nanostructures whose formations were directed by yeast and other single cells can create more secure homes for their occupants - even in the vacuum and radiation of outer space - than those created by more standard chemical procedures. Sandia is a National Nuclear Security Admini...

Tool developed to silence genes in specific tissues using RNAi

...e first transcription factor shown to regulate the formations of these junctions, Wilkinson says. "It is a transcription factor that dictates both the formation of the testes in the embryo, and the function of the testes after birth." Researchers worldwide have been trying to harness the power of RNAi since it...

Embryos tell story of Earth's earliest animals

...gh for fossilization to occur. "It appears these formations in China had the conditions that would have preserved animal embryos," Raff said. "Hopefully, the question about whether this can happen can be put to rest." What distinguishes animals from other organisms is the ability to ingest other organisms, ...

Cattle grazing may help rather than hurt endangered species

...ooked at 36 vernal pools on two different geologic formations on a 5000-ha ranch in eastern Sacramento County, California. Their experiments found that removal of grazing reduced the duration of wetland flooding by an average of 50 days per year. Their simulations show that climate change could compound these...

'Acid rain' and forest mass: Another perspective

...Magnesium deficiency was observed in all the adult formations studied. The acceleration of the return of nutrients and the drop in the efficiency of their use is proposed as an explanation of this disorder. Thanks to this investigation, it was concluded that the atmospheric deposition of contaminants produces ...

Study casts doubt on 'Snowball Earth' theory

...nnovative techniques to previously unexamined rock formations has turned up strong evidence on the "Slushball Earth" side of a decades-long scientific argument. The study appears in the Sept. 29 Science Express. The lead author is Alison Olcott, a Ph.D. student of earth sciences in the USC College of Letters, ...
