Circadian clock controls plant growth hormone

...es may be influenced by circadian rhythms. Auxin tells shoots to grow away from the ground and toward light and water. Charles Darwin conducted early experiments that showed how auxin affects plant growth. Most plants and animals have an internal clock that allows them to match their activities to the ti...

Human knowledge is based upon directed connectivity between brain areas

The participants in Gruber's study were asked to categorize objects that were subsequently presented on a screen either as familiar or u...

Synchrotron could help save the Tassie devil

...animals and healthy ones. The infra-red spectrum tells us about protein and fat structure and whether its changing, Dr Church says. But the technology to do such work using a synchrotron is comparatively new, and the Australian facility is one of relatively few around the world where it is available. I...

U-M researchers find family of 'on switches' that cause prostate cancer

...ions, represent different molecular subtypes. This tells us theres not just one type of prostate cancer. Its a more complex disease and potentially needs to be treated differently in each patient, says lead study author Arul Chinnaiyan, M.D., Ph.D., director of the Michigan Center for Translational Patholo...

Forsyth scientists gain new understanding of adult stem cell regulation

... regulation such as the message that maintain and tells a stem cell to specialize and to become part of an organ e.g.: liver or skin. In recent years, planarians have been recognized as a great model system to molecularly dissect conserved stem cell regulatory mechanisms in vivo. Planarians have powerfu...

Scientists take next step in understanding potential target for ovarian cancer treatment

...ortant role: transporting a messenger protein that tells components in the nucleus to stop cell growth. The discovery of this additional role may lead to diagnostic tools and earlier treatments for ovarian cancer. A Penn State College of Medicine research team, led by Kathleen M. Mulder, Ph.D., professor...

The scientists believe the extended source of particle pollution is reactive, colorless gases called Volatile Organic Compounds, or VOCs, the same gases that form sm...

How the Biotech Revolution Is Changing the Way We Fight Disease

...ist and veteran lab researcher Frank H. Stephenson tells the compelling story of how scientists on many fronts are succeeding in the battle against disease. According to Stephenson, efforts to understand the nature of disease, down to its component molecular foundation, have reached an unprecedented int...

University of Colorado invention may allow thirsty crops to signal farmers

...e Shop of Horrors," when a giant carnivorous plant tells humans to "feed me." "This technology allows plants to say, 'water me,' " he said. High eastern plains water-use has led to lawsuits against Colorado for violations of interstate water compacts, including a recent $30 million payment to Kansas f...

Mucosal-surface immune function discoveries could boost vaccine research

... APRIL, a cytokine-signaling chemical, essentially tells nearby B-cells to start producing the IgA2 antigen." IgA2 helps the immune system keep mucosal bacteria in check. So, as bacteria levels rise, so too do levels of IgA2, dampening the excessive growth of these otherwise helpful bugs. And there is ...

Scientists decode RNA mystery, will help aim drug therapies

...rug design. Defining the Codons Messenger RNA tells the ribosome what kind of proteins to make and how much to crank out. The codons specify which amino acids should end up in the protein, says Dinman. If the wrong codon is selected, the wrong amino acid ends up in the protein, which can alter or dest...

Given some exciting recent developments on testing possible cures for inherited blindness, its becoming very important for every...

Undergraduate research shows leaderless honeybee organizing

...kers give the queen a signal, known as piping that tells her to fly. Researchers have never reported worker piping being done on the queen before, so some of what we found was exciting, Pierce said. It was generally surprising to see the level of interaction that the older bees have with the queen. This ...

U-M researchers discover gene switched off in cancer can be turned on

... are not the perfect answer, but in principle this tells us we can turn our gene back on. If we can turn the gene back on, it may not be a cure for cancer, but it could slow it down or make it responsive to existing drugs, Reisman says. The researchers targeted lung cancer cell lines in particular, altho...
