Ultrasound may help regrow teeth

...e miniscule device will be able to fit comfortably inside a patient's mouth while packed in biocompatible materials. The unit will be easily mounted on an orthodontic or "braces" bracket or even a plastic removable crown. The team also designed an energy sensor that will ensure the LIPUS power is reaching t...

Carnegie Mellon researchers discover new cell properties

Islam, an assistant professor of chemical engineering and materials science and engineering, says that the increased stiffness of the lamina may be caused by mutant proteins self-o...

Scientist-astronaut sends T-cells into space

...will be carried to the International Space Station inside a specially designed incubator called Kubik, which was made to fit precisely under the cosmonaut's seat in the Soyuz spacecraft. Kubik contains a compartment for weightless experiments as well as a centrifuge that can accelerate cells in a range from...

Brittle prions are more infectious

...e strongest effect in producing protein aggregates inside cells. "But we knew from our model that growth was only half of the equation," said Weissman. "The other key feature was how easy it was to break up the prion and create new seeds, and this propensity to seed could be an important determinant of the ...

Rice scientists make first nanoscale pH meter

Genetically altered mice no longer like cocaine

...smitter dopamine from outside of a neuron into the inside of the cell ?is a prime target for developing drugs to fight cocaine addiction. "Cocaine blocks dopamine transporters, and this action ultimately is what makes a person feel high," Gu said. "We found that cocaine would not produce a high if it could...

Researchers identify genes in fruitflies that may shed light on human cancer spread

... genes involved in transporting materials from the inside of a cell to its membrane surface and back again. "So-called border cell migration shares common characteristics with metastatic cancer cells," says Xuejiao Wang, M.D., Ph.D., the first author of the study and a postdoctoral fellow in the Departmen...

Experimental drug reverses key cognitive deficits, pathology in Alzheimer's

...in cells and the protein "neurofibrillary tangles" inside the cells. In an article in the March 2, 2006, issue of Neuron, Dr. Frank LaFerla of the University of California, Irvine and his colleagues reported the first in vivo studies of the drug's effects. AF267B was developed by coauthor Abraham Fisher t...

'Scent of a woman' tells male redback spiders to find a mate

MIT researchers build tiny batteries with viruses

...ithium-ion batteries. By manipulating a few genes inside these viruses, the team was able to coax the organisms to grow and self-assemble into a functional electronic device. The goal of the work, led by MIT Professors Angela Belcher, Paula Hammond and Yet-Ming Chiang, is to create batteries that cram as ...
