Virologists make major step towards understanding the process of HIV infection

...ll. This is a major step towards understanding the process of HIV infection. Modern imaging technologies facilitate real-time observation of virus-cell interactions. Many of these investigation methods require labeling of the object of interest, such as by introducing the genetic code of green fluorescent p...

Scientists use manufacturing methods to reconstruct mastodon

...each bone using a device called a 3-D digitizer, a process that took three years for the whole skeleton. Next, technicians in the UM3D lab made the replacement bones with a rapid prototyping system that converts a digital representation back into a three-dimensional, physical object, building it up layer by ...

Atmosphere may cleanse itself better than previously thought

... now have a better understanding of an atmospheric process that could be giving our pollution-weary lungs more breathing room." Francisco's research, which he performed at the University of California, San Diego with two of that institution's scientists, lead author Amitabha Sinha and graduate student Jamie...

Some Brain Cells Change Channels

...her charged atoms that then keep the communication process going. In the cells in the cerebellum, a channel made of proteins called AMPA receptors, built from subunits called GluR3 and GluR4, is usually found at the synapse. If the cells are shocked with an electric current, within minutes the channels are ...

Newly discovered protein an important tool for sleeping sickness research

...) may play an important role in the gene silencing process behind antigenic variation. With the goal of learning how the organism regulates the process of antigenic variation, the scientists have been trying to understand how the trypanosome makes base...

Disabling gene defuses rheumatoid arthritis in mice

...illing themselves through a cellular self-destruct process known as apoptosis. Damaged or highly stressed cells can pull their own plug in this or a similar manner to prevent themselves from becoming cancerous. "It seems that evolution has somehow provided protective mechanisms for innate immune cells when ...

Active Vaccine Prevents Mice From Developing Prion Disease

...e dead by 300 days. The NYU scientists are in the process of redesigning the vaccine for deer and cattle. After choosing the appropriate bacteria for each vaccine, they must genetically modify it to carry the prion protein. "These technical issues are not major hurdles," says Dr. Wisniewski. "Developing a m...

NYU, Rockefeller researchers find complexity of regulation by microRNA genes

...nown about the biological function of microRNAs--a process the current study sought to explore. The paper, published in the latest issue of the journal Nature Genetics, found that a microRNA gene regulates, on average, 200 different human gene transcripts and that many microRNAs can coordinate their activit...

Researchers Closer To Helping Hearing-Impaired Using Stem Cells

...ion might greatly enhance the possibility that the process would result in development of specific sensory neurons.?/p> The research was published March 18 in the online early edition of the Proceedings of the National Academy of Sciences, and is scheduled to appear in the print edition of the journal Ma...

Computational Tool Predicts How Drugs Work In Cells, Advancing Efforts To Design Better Medicines

...elter of potential cellular targets means that the process of designing therapeutic drugs is neither precise nor efficient. The BU research team sought to bring precision and efficiency to this discovery process. The team used a combination of computational and experimental methods to build and verify their...

Researchers discover key gene involved in bark beetle pheromone production

...ists have ended a decade-long controversy over the process by which bark beetles make pheromones: they manufacture their own monoterpenes ?the fragrant substances plants produce and which are often used in perfumes. It had been thought that insects and other animals were incapable of making these substances....
