Anti-fungal drug stops blood vessel growth

...rs worked with cells from human umbilical cords, a rich source of blood vessels, and exposed them to 2,400 existing drugs - including FDA- and foreign-approved drugs, as well as nonapproved drugs that had passed safety trials - to see which ones could stop the cells from dividing. “The best outcome wa...

Magic Beans -- Anti-obesity soya could help prevent diabetes

A diet rich in black soya beans could help control weight, lower fat and cholesterol levels, and aid in the prevention of diabetes, reports Lisa Richards in Chemistry & Industry, the magazine of the SCI. Yellow soya has already been hailed for its cholester...

Unique tomatoes tops in disease-fighting antioxidants

Deep red tomatoes get their rich color from lycopene, a disease-fighting antioxidan...and tomato-based products we currently consume are rich in all-trans­-lycopene. "We don't know why our bodies seem to transform lycopene into cis-isomers...

Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal

ASU researchers test antibacterial effects of healing clays

...ments, particularly during pregnancy. The clay was rich in kaolinite. (Kaolinite is the major ingredient in the over the counter remedy Kaopectate). But one day, they ran out of clay and moved over to another mountain and people began dying. We wanted to know why." The key to clay's variable nature see...

Interaction between lymph and liver cells may affect immune response

...soid cells (gossamer-like structures that form the rich capillary network of the liver) and are perforated by fenestrations, or openings. The researchers hypothesized that the fenestrations could provide a portal through which liver cells and T cells could interact or that the interaction could take place...

Life in the extreme

...eeps in the Gulf of Mexico have revealed a habitat rich in biological activity and without a need for symbionts to extract nutrients. MacDonald found that the productivity of deep-water seeps is overwhelmingly based on chemosynthesis (deriving energy from chemical compounds instead of light) and also ...

A buffet for early human relatives

...t means the early human relative was eating a diet rich in C4 plants most commonly found on the African savanna, such as seeds and roots from grasses, and grass-like plants called sedges, which include tubers. They also may have eaten animals that grazed on C4 plants. If a sample has a relatively low...

Ocean seep mollusks may share evolutionary history with other deep-sea creatures

...res, he noted. Cold seeps are places where fluids rich in hydrogen sulfide and methane leak up through the ocean floor, creating a unique chemical environment where hardy bacteria process the sulfide and methane. Seep fluids are about the same temperature as surrounding waters, but similar chemically cha...

End of deforestation in view? Experts advance new way to size up global forest resources

...es on the expanse of natural forests, which may be rich in soil carbon and biodiversity," adds Dr. Sedjo. Implications for climate change In addition to the measurement of forest area and growing stock, the researchers offer a formula to calculate atmospheric carbon being stored incrementally in th...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...U.S. could provide a steady supply of tree biomass rich in cellulose that can be transformed by specialized biorefineries into fuels like ethanol. Other regions of the country might specialize in different "energy crops" suited to their particular climate and soil conditions, including such plants as swi...

Scientists discover role for dueling RNAs

...y. When conditions around yeast cells are good and rich in nutrients, the cells divide by mitosis--that is, the DNA duplicates so each daughter cell receives exactly the same number of chromosomes as the original cell. However, when the yeast cells are starving, IME4 switches on and activates a process ca...

Tiny bones rewrite textbooks

...y other mammal known. They were unearthed from the rich St Bathans fossil bed, in the Central Otago region of South Island. But the real shock to scientists was that it was there at all: until now, decades of searching had shown no hint that furry, warm-blooded animals had ever trodden on New Zealand so...

A natural chemical found in strawberries boosts memory in healthy mice

...ifruit and persimmons. Gingko biloba leaves, while rich in other flavonoids, do not contain fisetin. While eating strawberries sounds like an enjoyable alternative to popping a pill, Maher cautions that it would take about 10 pounds a day to achieve a beneficial effect, which might prove too much even f...

Genomic comparison of lactic acid bacteria published

Lactic acid-producing bacteria play a key role in the production of fermented foods and beverages, accounting for tens of bi...

Oldest animal fossils may have been bacteria

...om southern China's Doushantuo Formation, which is rich in phosphorite. The source for the rare mineral was unknown. Bailey wondered if an ancient relative of Thiomargarita might have been involved. "The idea is that these bacteria were causing these phosphorite deposits to form," Bailey said. Also ...
