Evolution is driven by gene regulation

...e able to see functional differences that had been invisible to researchers before, said Snyder. We expect that this approach will get us closer to understanding the balance between gene content and gene regulation in the question of human-chimp diversity. ...

Bright future for nano-sized light source

...ght wavelengths. For biology, this brings normally invisible subcellular structures into view. We hypothesized that a single potassium niobate nanowire would, when optically trapped, be able to double the frequency of the trapping light and then waveguide this locally generated light to its ends, thereby ena...

UN issues analysis of global investors' sustainable energy 'gold rush'

... Energy efficiency is a significant but largely invisible market, attracting increasing attention as investors realize its important role in meeting rising energy demand; Capital investors are now more closely aligned with industry proponents in their views of expected growth. Wind, solar, biofue...

Pendulum love, science class gender gaps, musical mind mirrors, and unparticle physics

...s carried away by a fractional number of otherwise invisible particles. So if LHC experimentalists happen to see signs of 3.34 ghostly particles, for example, they could be on the track of unparticle matter. Unparticle stuff may go the way of countless other defunct predictions of exotic phenomena. Unlike th...

FSU researchers reap $1-million grant to make medical implants safer

... cell membranes, certain polymers could be all but invisible to the human body," Schlenoff said. "What were seeking is a marriage of materials and biological cells. If we are successful at bridging the so-called biointerface where synthetic materials and cells meet, then the potential applications of this tech...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

...al microscope" that let them zoom in on previously invisible details -- is that initially the binding part of the enzyme moves freely and randomly across the cellulose surface, searching for a broken cellulose chain. When it encounters an available chain, the cellulose itself seems to prompt a change in the sh...

MIT's ocean model captures diversity of underwater forests

... is the first to reflect the vast diversity of the invisible forests living in our oceans-tiny, single-celled green plants that dominate the ocean and produce half the oxygen we breathe on Earth. And it does so in a way that is consistent with the way real-world ecosystems evolve according to the principles of...

New science of metagenomics 'will transform modern microbiology'

...s. "Metagenomics lets us see into the previously invisible microbial world, opening a frontier of science that was unimaginable until recently," said Jo Handelsman, Howard Hughes Medical Institute Professor, departments of plant pathology and bacteriology, University of Wisconsin, Madison, and co-chair of th...

National Academies advisory: March 27 release of report on metagenomics

...til recently, most of the microbial world remained invisible to scientists because the vast majority of microorganisms cannot be grown in laboratory culture to be viewed under a microscope. Now an emerging field of science known as metagenomics is allowing researchers to examine all of the genetic material of ...

Gold nanorods assemble themselves into rings

...y sensitive optical sensors, superlenses, and even invisible objects for use in the military. "Finding new ways to assemble nano-objects into superstructures is an important task because at the nanoscale, the properties of those objects depend on the arrangement of individual building blocks," said principal ...

Breast cancer treatment heats up

...ncealed in polymers and sugars, making them nearly invisible to the body's immune system. Antibodies (joined with a radioactive substance) on these probes latched onto receptors that are on the surface of tumor cells. The heating of the probes can be activated and controlled by the use of a magnetic field from...

UC Davis researchers use heated nanoprobes to destroy breast cancer cells in mice

...ked in polymers and sugars that render them nearly invisible to thebody's immune system. DeNardo and her colleagues infused trillions of the probes -- more than10,000 can fit on the end of a straight pin -- into the bloodstreams oflaboratory mice bearing human breast tumors. Once in the bloodstream, theprobe...

Super-thin membrane, 50 atoms thick, sorts individual molecules

A newly designed porous membrane, so thin it's invisible edge-on, may revolutionize the way doctors and scientists manipulate objects as small as a molecule. The 50-atom thick filter can withstand surprisingly high pressures and may be a key to better separation of blood proteins for dialysis patients, s...

Investigating the invisible life in our environment

Metagenomics experiments generating enormous amounts of data and new computational methods extracting meaningful information from it will provide a m...

Women in polluted areas at higher risk of cardiovascular disease

They're typically invisible to the human eye once they're in the atmosphere, though they may be visible in dense clouds as they come out of a tailpipe, smokestack or chimney, and are responsible for urban haze. "These soot particles, which are typically created by fossil-fuel c...

Bats in flight reveal unexpected aerodynamics

...d how bats fly, the researchers needed to make the invisible visible. The research team filled the test corridor with a fine mist of non-toxic aerosol particles to trace the airflow. As each bat flies down the corridor, she (all the test subjects were female) triggers a laser imaging device, which captures the...

Pinning it on the poison

Yet poison detection in practice was no easy matter and its findings were subjected to searching questions by an anxious, and often sceptical, public. At no time did these new scientific methods come unde...

McBride shows DNA detective work with paper-eating bacteria that 'glide'

These filaments were recently imaged in collaboration with Sriram Subramaniam and Jun Liu at the National Institutes of Health by cryo-electron tomography. "The filaments may be the cell's 'tires,' and th...
