Dig deeper to find Martian life

... is within the ice at Elysium, the location of the newly discovered frozen sea on Mars. The lead author, Lewis Dartnell, UCL Centre for Mathematics and Physics in the Life Sciences & Experimental Biology (CoMPLEX), said: "Finding hints that life once existed ?proteins, DNA fragments or fossils ?wou...

Microbes compete with animals for food by making it stink

...ted the trapping experiment in the marsh, but used newly thawed fish, fish soaked in antibiotic treated water and fish aged without antibiotics. They found that both freshly thawed bait and aged, antibiotic-treated bait attracted animals more frequently than traps containing aged, microbe-laden menhaden. ...

Key to zebrafish heart regeneration uncovered

.... "The new blood vessels show poor invasion of the newly regenerating cells, halting the formation of new heart muscle." Poss said that a continued understanding of the processes involved in regeneration of the zebrafish heart could lead to therapies to repair human heart muscle damaged by disease or he...

Science researchers genetically transform immune cells into tumor fighters

...ill now recognize common cancers," he notes. The newly engineered T cells showed signs of persistence in 15 of the patients in the study, making up at least 10 percent of their circulating T cells for at least two months after treatment. New T cell levels were higher in the two people whose tumors shrunk...

Vaccine-producing 'plant-factories'

...ncapable of producing glycosylate proteins. The newly discovered route connects the cell organ where the proteins are glycosylated, the reticulum, with the chloroplasts. This discovery signifies the first step in the development of plants and algae that accumulate in their chloroplasts large amounts of ...

Einstein researchers demonstrate a novel approach to treating AIDS

...unotherapy might be particularly useful for people newly exposed to HIV, such as healthcare workers with needlestick injuries. "Studies show that giving highly active antiretroviral therapy (HAART) to people within 24 hours of exposure to HIV can prevent infection from developing," he says. "But if several...

Ocean sampling yields environmental sources of coral symbionts

...h generation. However, it has remained unclear how newly settled coral polyps acquire their symbionts in the ocean. Organisms that resemble coral symbionts—dinoflagellates that are similar to those of the Symbiodinium genus that grow within corals—have been isolated from both sand and the water column; how...

Researchers identify a key regulator for skin stem cells

...aining the stem cells in their immature state. The newly identified repressor switch could provide part of the answer. Led by Howard Hughes Medical Institute investigator Elaine Fuchs, the researchers published discovery of this regulator, known as Tcf3, in an article in the October 6, 2006, issue of th...

New technique boosts size of proteins that can be analyzed

...re, the method rarely locates all modifications in newly isolated proteins. "Each approach has different strengths and weaknesses," said Mi Jin, a postdoctoral associate in chemistry and chemical biology and one of the paper's lead authors with fellow graduate student Xuemei Han. Jin said that the bottom...

First Quantum Grant to fund stem cell repair of damage from stroke

...nstitute of Biosciences and Bioengineering. The newly created NIBIB Quantum Grants Program supports researchers in the development of innovative biomedical technologies in hopes of making a significant impact in the prevention, diagnosis and treatment of disease. Funding was awarded to only one grant ap...

One signal elicits thousands of answers

... these phosphorylation sites are now listed in the newly created Phosida database to make them available for efficient use by scientists working in different areas, among them tumour researchers: Defects in cellular signaling often occur in many types of cancer (Cell, November 2, 2006). The mammalian ce...

Genetic surprise confirms neglected 70-year-old evolutionary hypothesis

...imulans," says Masly. As the simulans' genome was newly sequenced, Masly called a colleague, geneticist Corbin D. Jones, a co-author of the paper and Rochester graduate, who was studying the simulans genome. Over the phone one day in the lab, Jones told Masly what his analysis turned up. "You're not go...

Virus may control Australia's

Supported with $355,000 from the newly formed Invasive Animals Cooperative Research Centre and the Murray-Darling Basin Commission, the two-year project will investigate the effectiveness of Koi herpesvirus in controlling strains of carp present in Australia and will examine whether the v...

What does the public really know about HPV?

...te high levels of exposure to and awareness of the newly approved HPV vaccine, intentions to vaccinate are mixed," said Amy Leader, MPH, Research Director, EPIC Center of Excellence in Cancer Communication Research. "Trends indicate that intentions are highest when the vaccine is framed to solely prevent ...

Study IDs protein that inhibits HIV from growing in cell cultures

...ty VA and UI. The current study shows that the newly identified protein, NS5A, inhibits HIV in part by decreasing the number of CD4 receptors available to HIV. With fewer places for HIV to "dock," less HIV enters the cells to inflict destruction. However, Xiang cautioned, this is only part of the s...

Siberian lakes burp 'time-bomb' greenhouse gas

...ere enhancing climate warming," Walter said. "This newly recognized source of methane is so far not included in climate models." Using remote sensing, aerial surveys and year-round, continuous measurements Walter and colleagues developed a new method of measuring ebullition (bubbling) point sources and us...

Novel regulatory mechanism identified for key tumor suppressor p53

...f suppressing cancer. Unusually high levels of the newly identified enzyme might also be useful as a diagnostic marker for cancer." Responsible for tumor suppression throughout the body, the p53 protein has been found to be mutated and dysfunctional in more than half of human cancers. When working proper...

Nanotech tools yield DNA transcription breakthrough

"Our findings were made possible by newly developed, single-molecule methods," said Ebright, a Howard Hughes Medical Institute investigator and professor of chemistry and chemical biology at Rutgers, The State University of New Jersey. "These methods enabled us to analyze and manipulate indi...
