Definitive evidence found of a swimming dinosaur

...e trackway consists of 6 asymmetrical pairs of 2-3 scratch marks each. Each set of scratch marks, preserved in a layer of sandstone, averages approximately 50 centimeters in length and 15 cen...

Newborn brains grow vision and movement regions first

...e findings are intriguing, Gilmore said, they just scratch the surface of an area that has been little studied so far and in which much more research needs to be done. "This study gives us the first glimpse that there are regional differences in how quickly the brain is growing, and these regional differen...

Researchers create artificial enzyme that mimics the body's internal engine

...rate sequence of 32 chemical steps, was built from scratch and took several years to develop. The site contains the three active centers found in the naturally occurring enzyme: an organic molecule called phenol, an iron atom and a copper atom. Working together, these three centers provide the four electr...

New technique boosts size of proteins that can be analyzed

Results with newer bladeless LASIK equivalent to standard microkeratome LASIK

...ct vision, but rather the potential to heal from a scratch or other injury to the eye. High-contrast visual acuity, the capability to see fine details, and contrast sensitivity, the ability to perceive contrast in objects and their environments, also did not differ between LASIK types. The researchers found ...

Researchers solve mystery of how nuclear pores duplicate before cell division

...rmed but also to demonstrate that they formed from scratch without the help of already existing pores." In another experiment, the group used four-dimensional confocal microscopy to follow the formation in cultured human cells of a single pore that had been labeled with a fluorescent tag. If the nuclear po...

The closest look ever at the cell's machines

...htmare if the cell had to build every machine from scratch any time it needed to do something," says Anne-Claude Gavin, former Director of Molecular and Cell Biology at Cellzome and currently a team leader at EMBL. "We've discovered that the reality is different. Cells use a mixed strategy of prefabricating ...

Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm

... took the unconventional approach of starting from scratch and not looking at genes already known or suspected to be involved in heart rhythm. "Studying individual genes is not going to open new areas of research," says Chakravarti. "Using a whole-genome approach allows us to find new targets that we never...

New complete muscle grown in the lab

...etts Institute of Technology, grew the muscle from scratch by seeding a sponge-like, three-dimensional plastic scaffold with myoblasts and endothelial cells, which are the precursors to mature skeletal muscle and blood vessel cells. The researchers also added connective tissue cells called fibroblasts to the...
