Rutgers biomedical engineering professor solves golf grip mysteries

...atent-pending measurement method may eventually be adapted for use as a bio-feedback golf instruction tool, Hung said. "It would allow players to assess precisely when their own eye movement, head movement and putting style produce the most effective results." Hung's tests were conducted with seven novice p...

Researchers discover clues to whale evolution

...ible for balance and located in the inner ear, was adapted to aquatic life approximately 45 million years ago. The discovery will be published in the May 9 issue of the journal Nature. Cetaceans (whales, dolphins and porpoises) have unique semicircular canals that allow them to be highly acrobatic swim...

...tors. One conclusion is that different species are adapted to survive over different time scales and that this leads to a different range of surviving species than if selection worked only at one time scale.

If so, vegetables native or adapted to various regions could be used by local populations to reduce helicobacter infection, notes Fahey, who has compiled a list of vegetables that contain sulforaphane or related compounds. "We've known for some time that sulforaphane had modest antibio...

People linked to new sea otter diseases

...ke common species become rare because they are not adapted to the new pathogen. For instance, introduced bird malaria has decimated many Hawaiian song birds that used to be common. "Many of these wildlife diseases are viewed as emerging, particularly as we introduce species around the globe and as our domest...

Membrane filters offer options for cleaner water

... their performance and determine how they might be adapted for large-scale use. Membranes are made out of various materials and come with different pore sizes, which determine the size of the contaminants that can be filtered out. The goal is to optimize the combination of membrane material and pore size to ...

New method for 'visualizing' proteins

... as proteins and membranes. The research group has adapted this technology, dubbing it DQC (for double quantum coherence), to deliver pulses of microwave radiation in appropriate sequences in order to measure the distances between two spin labels. These are molecular subunits, each containing an unpaired ele...

Just one bite at a time: Researchers find snake with unusual feeding habit

... apart was a surprise, because snake teeth are not adapted for slicing and cutting. Instead, they curve back into the mouth which is an adaptation for holding the prey inside the mouth. Fordonia, on the other hand, has no stereotypical behavior for pulling its crab prey apart, although they do occasionally b...

Changing fish body shapes give clues to environmental factors

...ofish, is one such fish found in the study to have adapted to being raised with predators by growing a longer tail. That's important, he said, because the state has several endangered species of Gambusia. "Anything we learn about the 'weed' species can inform us about conservation planning for the endangered...

In particular, the low-crowned teeth of herbivores reveal that they fed on soft-leaved forest vegetation rather than grasses, and future analysis of c...

New microscope technology allows study of biomolecules interacting with minerals

...impact the quality of our environment and could be adapted for our use. Imagine a falconer releasing his falcon to nab pigeons for his dinner. That is somewhat how the bacteria, Azotobacter vinelandii, acquire iron. They release siderophore molecules, called azotobactin, which nabs iron out of minerals. "The...

New method of DNA testing promises to transform medical diagnostics

...irect detection of the invader, and can be readily adapted to direct detection of other invaders merely by altering the PNA. We already have huge DNA data banks; the tester just has to get the complementary PNA." "You can buy the PNA," said Bazan. "A supply chain for these components is in place. "You can...

Rutgers spinoff success yields $4.3 million payback to university

"The increasing cost of energy and chemical raw materials, combined with the environmental concerns associated with conventional pharmaceutical manufacturing, will make plants even more desirable as source...

Wilmington researchers receive award for using chemistry to protect food supply

The Heroes of Chemistry program, started in 1996, honors industrial chemists and chemical engineers who create commercially successful products that improve the quality of life. The theme of the aw...

Scientists confirm age of the oldest meteorite collision on Earth

"It looks like what we are seeing is a much greater rate of the large impacts on the early Earth, certainly than we have today, and perhaps even a much greater rate than what was suspected," Lowe concluded. "I thi...

Sequence provides insights into a pathogen's virulence mechanism allowing for vaccine development

...e differences probably relate to how S. agalactiae adapted to distinct niches in its human and bovine hosts, the paper suggests. The researchers also found genes unique to S. agalactiae that likely play a role in colonization or in disease: genes related to surface proteins, capsule synthesis, and the hemoly...

Not only are the smart-dust crystals small in size, inconspicuous and capable of detecting thousands of possible agen...

Scientists at the Scripps Research Institute discover how a plant times its flowering cycle

These forms may occupy different ecological niches, and gene flow between the forms may be restricted in some instances. Sc...
