Science Sunday: Wrap-up of recent advancements in science from EurekAlert!
Quasicrystals: Somewhere between order and disorder:
Until 1982, quasicrystals weren't just undiscovered, they were believed to be physically impossible. In new research published in July's issue of the Journal of the American Mathematical Society, mathematicians David Damanik and Serguei Tcheremchantsev offer a key proof in the study of quasicrystals. The work, which was 10 years in the making, sheds new light on the electrical properties of these mysterious materials.
Resistance genes in our food supply:
Could the food we eat be contributing to the continuing rise of antibiotic-resistant infections? Harmless and even beneficial bacteria that exist in our food supply may also be carrying genes that code for antibiotic resistance. Once in our bodies, could they transmit the resistance genes to disease-causing bacteria?
Scientists from the UGR are using olive stones to depollute industrial sewage water:
Research carried out by the Department of Chemical Engineering makes it possible to remove chrome, a hard metal which can be dangerous for humans. The process is based on biosorption, which is a property of certain types of biomass to retain pollutants. It can be used to purify water from painting, tannery or the galvanizing industry, among others.
UGA study reveals function of ubiquitous yet poorly understood microorganisms:
A new study led by University of Georgia researchers and announced on Wednesday at the American Society for Microbiology meeting in Toronto finds that crenarchaeota, one of the most common groups of archaea and a group that includes members that live in hot springs, use ammonia as their energy source. Such a metabolic mode has not been found in any of the other known high-temperature archaea.
New adult brain cells may be central to lifelong learning:
The steady formation of new brain cells in adults may represent more than merely a patching up of aging brains, a new study has shown. The new adult brain cells may serve to give the adult brain the same kind of learning ability that young brains have while still allowing the existing, mature circuitry to maintain stability.
Tiny genes may increase cancer susceptibility, Jefferson scientists find:
New evidence indicates that small pieces of noncoding genetic material known as microRNAs (miRNAs), which play various roles in biological regulation, including development and cell differentiation, might influence cancer susceptibility. Researchers found that miRNAs appear to be frequently located near places in the mouse genome that affect such susceptibility, suggesting that differences in certain miRNAs may predispose some individuals to develop cancer.
Novel sugar-to-hydrogen technology promises transportation fuel independence:
Researchers at Virginia Tech, Oak Ridge National Laboratory and the University of Georgia propose using polysaccharides, or sugary carbohydrates, from biomass to directly produce low-cost hydrogen for the new hydrogen economy. The vision is for the ingredients to be mixed in the fuel tank of your car, for instance, to power a fuel cell.
Hydrogen breakthrough could open the road to carbon-free cars:
A new breakthrough in hydrogen storage technology could remove a key barrier to widespread uptake of non-polluting cars that produce no carbon dioxide emissions.
Exercise reverses aging in human skeletal muscle:
Exercise is now the first scientifically proven "anti-aging" medicine for humans. The muscles of healthy seniors who did six months of resistance training actually rejuvenated.
Mother birds 'engineer' their offspring:
Bird species that have relatively long incubation periods and short nestling periods for their body size have higher concentration of androstenedione than those species whose developmental time is shifted towards relatively longer stays in the nest than in the egg. This is an advantage depending on the predators. There is a relationship between egg levels of androstenedione and colony size, suggesting that mothers prepare their offspring for the social conditions.
Jet lag: It's all about chemical reactions in cells:
New research by Cornell and Dartmouth researchers explains the biological mechanism behind how circadian clocks sense light through a process that transfers energy from light to chemical reactions in cells.

New fabrication technique yields nanoscale UV LEDs:
Researchers at NIST, in collaboration with scientists from the University of Maryland and Howard University, have developed a technique to create tiny, highly efficient light-emitting diodes from nanowires.
