American Chemical Society Weekly PressPac -- April 8, 2009

... limited by the materials they cover. A rubber band dipped in molten wax is a good case in point. Once hardened at room temperature, the wax is several times harder and stiffer than the underlying rubber, but even ...

Scattered light rapidly detects tumor response to chemotherapy

... that multiple mechanisms are involved in these early events in apoptosis," wax said. "Further analysis showed the early changes we observed were taking ... human breast cancer, further studies will be carried out in animals. wax and colleagues at the University of North Carolina at Chapel Hill are ...

Wet ear wax and unpleasant body odors signal breast cancer risk

... most people can't miss unpleasant body odors," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal , "As it turns out, the type of ear wax one has is linked to a gene that leads to bad odors from one's armpit. These may become lifesaving clues to the early detection and treatment of ...

Doubling a gene in corn results in giant biomass

... the energy to make the seed goes instead into the stalk and leaves. "We had been working with this gene for awhile. We thought there would be more wax on the leaves and there was. But we also got this other benefit, that it's a lot bigger." Moose tested his hypothesis with other corn lines and ...

Discovering the secret code behind photosynthesis

... - using the same telegraph system as the one found in 'primitive' bacteria. It would be like discovering Morse code in your computer network, or a wax cylinder at the heart of your new, shiny digital HiFi. To us, however, the discovery is exciting evidence for an unorthodox theory of cell evolution ...

Radioactivity: Discover the lowest amounts with new methods

... parameters temperature, air humidity and aerosol content can be adjusted and controlled. Analogue to the radon reference chamber, Carnauba wax aerosol is used as model aerosol. The activity concentrations of thoron and of the thoron progenies shall be adjusted by means of several open ...

Drought tolerance in potatoes

... increased, lowering osmotic potential, to induce uptake of water from drying soils. Increased expression of lipid transfer genes and fatty-acid and wax synthase genes suggested the reinforcement of cell membranes and cuticles. Genes for cell wall components were also upregulated, as were ...

A compound extracted from olives inhibits cancer cells growth and prevents their appearance

... A research group of the University of Granada has found out that maslinic acid, a compound present in the leaf and the olive skin wax extracted from alpeorujo (crushed olive pulp), has the capacity of preventing cancer as well as regulating apoptosis in carcinogenic processes. ...

Light-based probe 'sees' early cancers in first tests on human tissue

... patients to avoid removal of tissue for biopsy, wax said. In other instances, he added, fa/LCI could ... for a cancerous lesion to escape detection. wax and his former graduate student John Pyhtila ... "Our initial study is very promising," wax said of the findings. "We looked at tissue ...

Newly recognized gene mutation may reduce seeds, resurrect plants

... found the gene while studying a unique surface wax mutant of Arabidopsis, a common laboratory research plant. All plants have a certain amount of wax overlaying leaves and stems. The abnormal ... mutant Arabidopsis showed alterations only in wax and seed development, but not in the other ...

MIT's ocean model captures diversity of underwater forests

... finally modeling the ocean systems in a way that is consistent with how biologists think of them-water filled with millions of diverse microbes that wax and wane in relative abundance through interactions with each other, and the environment, as dictated by natural selection," said Chisholm. ...

MIT's ocean model precisely mimics microbes' life cycles

Contrary to common wisdom, scientist discovers some mammals can smell objects under water

... the bottom of a glass tank. Then he stuck various objects on the bottom of the tank ?pieces of earthworm, small fish, insect cuticle and blobs of wax and silicon ?and observed the moles' behavior. He saw that, when the moles approached one of these targets, they would blow bubbles that came into ...

UGA study explains peaks and troughs of dengue epidemics

... Scientists have long known that epidemics of dengue fever wax and wane over a period of several years, but they've never been quite sure why. With the incidence and range of the potentially deadly mosquito-borne ...

Technique makes it easier to see mouse embryo in all its glory

... found a way to make the analysis much faster '" and more accurate. Traditional histology involves embedding embryos in wax, thinly slicing the wax and delicately placing it on slides, staining the sections and viewing slides under the microscope, then mentally reconstructing the ...

Ants win a waxy race

... The legs of the specialist ant Crematogaster contains two claws and an adhesive pad. Bruening performed experiments with ants running along glass and wax rod, clipping off their claws or pads to assess the essence of these components. She observed that, as it approaches a waxy surface, the ants use ...
