Mystery of fossilized trees is solved

... how large the plant could grow. The new specimens show that they reached at least 8 metres in height and formed the first known forests on earth. Dr Berry, of Cardiff's School of Earth, Ocean and Planetary Sciences, said: "This is a spectacular find, which has allowed us to recreate these early forest...

Gallium: A new antibacterial agent?

...inical Investigation, Pradeep Singh and colleagues show that Gallium (Ga), which is chemically similar to Fe and can disrupt biological systems by substituting for Fe, inhibits the in vitro growth of Pseudomonas aeruginonsa; even multidrug resistant strains of P. aeruginonsa isolated from individuals with...

Xie Lab demonstrates the role of microRNA pathway

... expression of other genes. The Xie Lab's findings show that the microRNA pathway is essential for controlling self-renewal of two types of stem cells in the Drosophila ovary. "The findings were interesting to us because they demonstrated that the microRNA pathway is essential for controlling self-ren...

Ethanol vehicles pose a significant risk to human health, study finds

...l and environmental engineering. ''But our results show that a high blend of ethanol poses an equal or greater risk to public health than gasoline, which already causes significant health damage.'' Gasoline vs. ethanol For the study, Jacobson used a sophisticated computer model to simulate air qua...

Intravenous nanoparticle gene therapy shows activity in stage IV lung cancer

...post-treatment biopsies of three patients' tumors show that expression of FUS1 was absent from pretreatment samples while a high level of FUS1 was expressed in tumors after treatment. FUS1 can induce apoptosis - programmed cell death - in cancer cells but is frequently lost when normal cells become ca...

Napoleon's mysterious death unmasked, UT Southwestern researcher says

...a sign of gastric cancer. The autopsy descriptions show that Napoleon's stomach was filled with a dark material that resembled coffee grounds, an indication of gastrointestinal bleeding that likely was the immediate cause of death, Dr. Genta said. The most important description was of a large, ulcerated l...

Birth rate, competition are major players in hominid extinctions

...rest, early hominid cultures 2.5 million years ago show signs of the ability to live in marginal areas and live on more dynamic, seasonal landscapes," Jablonski told attendees today (Feb. 16) at the annual meeting of the American Association for the Advancement of Science in San Francisco. Through ti...

Researchers discover genetic cause for word-finding disease

...xact statistics are available. People can begin to show symptoms of PPA as early as in their 40's and 50's. Scientists discovered the gene mutation, called a progranulin gene mutation, in two unrelated families in which nearly all the siblings suffered from PPA. In the first family, three out of four s...

Nanotechnology shows promise as next wrinkle fighter

... manufacturing process, Ilsoon said the principles show promise to apply to human skin. The research is supported by the National Science Foundation and the Michigan Economic Development Corp. On all fronts, it's all about nailing a wrinkle before it starts. "Everything starts at a really small sca...

Discovery of an HIV inhibitor in human blood points to new drug class

...cause multi-drug resistant viruses are starting to show up more and more," Kirchhoff said. "In at least some industrialized countries, it is already a severe problem." ...

Scientists unlock secret of what makes plants flower

...he fluorescent version of FT. This allowed them to show conclusively that FT protein moved from where it was produced in the leaves of one plant, across into the other plant. The FT protein is produced when the FT gene is switched on by another gene known as CONSTANS. This is a key gene expressed in l...

Study uncovers a lethal secret of 1918 influenza virus

...cting monkeys with the virus, the team was able to show that the 1918 virus prompted a deadly respiratory infection that echoed historical accounts of how the disease claimed its victims. Importantly, the new work shows that infection with the virus prompted an immune response that seems to derail the b...

Gene chips forecast ecological impacts of climate change

...than temperature stress alone. Data presented will show how gene chips and other molecular approaches can assist in understanding how marine invertebrates are responding to the climate-change related multiple stressors in the world's oceans.

Studies yield insight into the numerical brain

... to associate symbols with numbers. "Our results show that, at least in the adult brain, numerical symbols and nonnumerical numerosities converge onto shared neural representations," they wrote. "Perhaps we attach meaning to symbols by physically linking populations of neurons sensitive to symbol shapes...

Gene study shows three distinct groups of chimpanzees

...go, Harvard, the Broad Institute and Arizona State show that there has been very little detectable admixture between the different populations and that chimps from the central and eastern populations are more closely related to each other than they are to the western "subspecies." They also devised a...

Protein found to shield pancreatic cancer cells from self-destruction

..., the researchers caution. The researchers also show that the TG2 pathway also is separate from another, better known, form of programmed cell death called apoptosis. Apoptosis, like autophagy, is a normal biological defense mechanism that systematically destroys defective cells by forcing them to k...

Tumor cells evade death through autophagy

...nical Investigation, Craig Thompson and colleagues show that in a tumor in which apoptosis was induced by activation of p53 expression, autophagy was observed only in tumor cells not undergoing apoptosis. If mice were unable to initiate autophagy, increased numbers of tumor cells undergoing apoptosis were...

Biodiesel won't drive down global warming

The results show that biodiesel derived from rapeseed grown on dedicated farmland emits nearly the same amount of greenhouse gas emissions (defined as CO2 equivalents) per km driven as does conventional diesel. However, if the land used to grow rapeseed was inste...

New test for most virulent HPV strains under study

...when he lectures around the country and asks for a show of hands of physicians using HPV tests in women over 30, few go up; he hopes that will change. “I think it’s a possibility in the future that we won’t be doing Pap smears on women over 30; it might just be screening with an HPV test. A lot of expe...
