DNA's twisted communication: Genome organization key element for control of gene expression
During embryo development, genes are dynamically, and very precisely, switched on and off to confer different properties to different cells and build a well-proportioned and healthy animal. Fgf8 is one of the key genes in ...
Isotope fingerprints: Jaisi laboratory tracks chemicals in water, farmland throughout Mid-Atlantic
University of Delaware researcher Deb Jaisi is using his newly established stable isotope facility in the Environmental Biogeochemistry Laboratory (EBL) to find the fingerprints of isotopes in chemical elements—specifically ...
Stem cells: Keeping differentiation in check
Researchers at the A*STAR Institute of Medical Biology (IMB) have discovered a critical checkpoint protein that controls when human embryonic stem cells (hESCs) begin to differentiate.
New model facilitates predictions about how nanoparticles form, gives clues about how process can be controlled
(Phys.org)—Nanoparticles are versatile harbingers of hope: They can serve as active medical agents or contrast media just as well as electronic storage media or reinforcement for structural materials. Researchers ...
Lattice location determination of trace nitrogen dopants in semiconductor silicon carbide (SiC)
AIST researchers have developed an instrument for X-ray absorption fine structure (XAFS) spectroscopy equipped with a superconducting detector. With the instrument, the researchers have realized, for the ...
Researchers explore more efficient carbon dioxide to methanol model
Researchers from The University of Texas at Arlington are pioneering a new method for using carbon dioxide, or CO2, to make liquid methanol fuel by using copper oxide nanowires and sunlight.
The cradle of the nanoparticle
Nanoparticles are versatile harbingers of hope: They can serve as active medical agents or contrast media just as well as electronic storage media or reinforcement for structural materials.
Building a biochemistry lab on a chip
(Phys.org)—Miniaturized laboratory-on-chip systems promise rapid, sensitive, and multiplexed detection of biological samples for medical diagnostics, drug discovery, and high-throughput screening. Using ...
Swimming-pool ships make waves in modular robotics (w/ Video)
X-rays reveal uptake of nanoparticles by soya bean crops
Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analysed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout ...
First evidence discovered that water once dissolved the surface of Mars
(Phys.org)—Scientists at the University of Glasgow together with the Scottish Universities Environmental Research Centre and the Natural History Museum (London) have discovered the first evidence of water ...
Jamaica breaks ground on rare-earth project
Jamaican and Japanese officials on Monday launched a pilot project designed to investigate whether rare-earth elements can be commercially extracted from the island's bauxite waste.
Promiscuous females are trying to avoid selfish genes
So-called 'selfish genes' may make females more promiscuous and also lower male fertility.
Low density of Earth's core due to oxygen and silicon impurities
During accretion and differentiation of the Earth, chemical interactions in a silicate magma ocean and liquid iron drove silicon and oxygen impurities into what went on to become the liquid outer core. Contrasting ...
