Award-winning INEEL probe to help safely monitor hazardous waste sites

...surviving a high-speed car crash while having four grown elephants on top of it. Since GEOPS will withstand forces of a direct installation, workers can bypass risky digging. They can push its casing straight into waste sites, Clark says, or else use a sonic drill that vibrates equipment into the ground wi...

Experimental drug prevents vaginal simian HIV transmission in monkeys Science study says

...centrations sufficient to block infection in cells grown in the laboratory. Many factors could be responsible for this in dose disparity between live animals and cultured cells, including difficulties getting the drug to all targets within mucosal membranes of the animals. In addition, the progesterone tre...

Muscling in on a deadly cancer

...eviously found that maturing skeletal muscle cells grown in the laboratory can revert to muscle stem cells. The Utah research found that tumors arising from mature or nearly mature muscle in mice have some characteristics of stem cells. That suggests the "primitive-appearing [rhabdomyosarcoma] tumors may b...

Using fruitflies to examine alcohol tolerance

...and analysis of genes. Additionally, flies can be grown for experiments relatively rapidly and inexpensively." For this study, researchers exposed flies to either a single intoxicating dose of alcohol (rapid tolerance), or to a low concentration of alcohol continuously during a 48-hour period (chronic to...

UCLA scientists discover new way to fix defective gene

...at earlier contained little or no ATM proteins had grown full-length ATM proteins. When the researchers tested the treated A-T cells, they also discovered that the cells had converted to normal appearance and begun to function normally. The cells started churning out ATM protein, which provides energy b...

...iest stages because cancerous lesions in the colon grown slowly and often without symptoms. More than 148,000 new cases of colon cancer are diagnosed in the U.S. each year and more than 56,000 Americans die of the diseases annually, according to the American Cancer Society. In order to arrive at a more ...

UF scientist: 'Brain' in a dish acts as autopilot, living computer

...LE, Fla. --- A University of Florida scientist has grown a living "brain" that can fly a simulated plane, giving scientists a novel way to observe how brain cells function as a network. The "brain" -- a collection of 25,000 living neurons, or nerve cells, taken from a rat's brain and cultured inside a gl...

Genetically endowed worm may substitute for rodents in some toxicology testing

... each of the toxins." Whole flasks of worms can be grown and dosed with chemicals before having the messenger RNA extracted from their cells. The amount of each messenger RNA molecule, which carries instructions from genes on how to build proteins, can then be measured on custom microarr...

UGA scientist Moran receives $2.6 million from Gordon and Betty Moore Foundation for marine research

...ion Web site, the field of marine microbiology has grown rapidly because of advances in technology and techniques for studying the genetic diversity of ocean microbes. Among these advances is the ability to study these microbes through DNA sequencing, DNA probes and cloning of large segments of microbial...

Researchers discover transport molecule that allows boron into cells

...Muallem's group showed that human cells with NaBC1 grown in culture specifically took up boron from solution when compared to arsenic, which is chemically similar to boron. Arsenic was unable to enter cells. Similar activity was found in many cell types isolated from mouse and rat tissues. Dr. Muallem...

Sea change: Skeletons of ancient corals different from today's

New program examines stem cells' potential to repair, replace damaged tissue

... cells from one of these patients could one day be grown into needed replacement organs and tissue. Each cell type has a distinct framework or matrix that will be used like the frame of a building to construct what's needed. "We are moving from doing transplantation, like renal transplantation, where we h...

Reassuring findings from first study on sperm donor identification

...n by The Sperm Bank of California (TSBC). Most had grown up knowing their history and the average age of learning about it was well under seven. By the age of 10, all had been told. The study is important because little research is available about the experiences of donor insemination families who have ope...

Molecular technique shows promise in destroying drug resistance in bacteria

...atment was applied to bacterial cultures that were grown for 250 generations. By the end of the experiment, the plasmids no longer were present, making it possible for antibiotics to work. "This is the first demonstration of a mechanistic-based approach to systematically eliminate the plasmids," Hergenroth...

Tropical birds sensitive to environmental cues that can be impacted by global warming

...orrespondingly, the song control nuclei were fully grown in the breeding Papallacta population when they were regressed in the nonbreeding Pintag population. Singing behavior also changed seasonally in both populations. "Our observations of seasonal brain plasticity in these tropical birds demonstrate tha...

Visualizing the end of the human genome

...and abnormal, circular chromosomes. In human cells grown in the laboratory, too much POT1 can be disruptive, causing abnormal lengthening or shortening of telomeres. Prior to determining the structure of human POT1, the researchers' prediction of what it might look like was based on their understand...

Scientists achieve self-assembly of spider silk fiber in insect cells

...us. These genetically engineered viruses were then grown in cultures of cells derived from a type of caterpillar called the fall armyworm. "Since spiders and insects are both arthropods and since their genomes are more closely related to each other than to those creatures with which prior experiments were...

Scientists generate human islet precursor cells in culture
