Overfishing in inland waters reduces biodiversity and threatens health

...000 constituted an estimated 15.3 percent of human consumption of animal protein. About 1 billion people rely on fish as their primary protein source. Landings from inland waters have increased more than fourfold since 1950, mainly in developing nations, though in developed countries, in contrast, catches have d...

Genetic and environmental influences on alcohol consumption among rhesus monkeys

Human albumin from tobacco plants

...nfections and renal or liver illnesses. The annual consumption in Spain is about 10 tons but, at a worldwide level, the demand exceeds 500 tons. Agricultural engineer, Alicia Fernández San Millán, has developed a novel technique in Spain - plastidial transformation, in order to produce, in a recombinant form, h...

Evidence for omega 3 fats less conclusive than we thought, say experts

...editorial. Health recommendations advise increased consumption of oily fish and fish oils. However, industrial fishing has depleted the world's fish stocks by some 90% since 1950, and rising fish prices reduce affordability particularly for people with low incomes. Global production trends suggest that, althou...

Darkness unveils vital metabolic fuel switch between sugar and fat

...ular switch in mammals that shifts the body's fuel consumption from glucose to fat and induces a state of torpor in mice, a research team led by scientists at The University of Texas Medical School at Houston reports in the Jan. 19 edition of Nature. While their findings could provide new insight into mammali...

Butterflies lose body fat during metamorphosis

... eggs. On a daily basis, they measured the food consumption of the larva and then analyzed the fatty acid composition and content of the diet as well as the larva. Once the larva had transformed into butterflies, the researchers examined the fatty acid composition and content of the butterfly. They found ...

Curry and cauliflower could halt prostate cancer

... in India. This has been attributed to the dietary consumption of large amounts of plant-based foods rich in phytochemicals ?nonnutritive plant chemicals that have protective or disease-preventive properties. Consequently, scientists have been investigating intervention options based on compounds found in edib...

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

...ely on an electric engine without need for oxygen consumption at lower speeds. Cells consume glucose through its main energy-producing machine, the mitochondrion, when oxygen is ample. But like the internal combustion engine, this process generates pollutants or toxic oxygen molecules. At lower oxygen level...

New crop of technology reveals plant health

... with embedded protocol software to minimise power consumption and maximise data throughput. What's more, these chips work wirelessly and contain their own batteries. They can communicate over large distances for their size, with a current range of about 10m, but again the Tyndall team hope to push their range f...

Alaska seal pup diet may hold key to decline of population

...ing to a better understanding of the role that fat consumption plays in the life of the harbor seal and could tie the declining population of seals and other marine mammals with the change in availability of seal prey, including herring," lead author Lori Polasek said. *Paper presentation: "Growth and body cond...

Attacking cancer's sweet tooth is effective strategy against tumors

...ane potential of tumor cells. What is more, oxygen consumption increased in the knockdown cells, suggesting they were reverting to the mitochondrial OXPHOS pathway--a kind of Warburg effect in reverse. "The findings provide us with an insight into a mechanism that had been suspected in the last six or seven deca...

Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

...ounsel. Although there is no evidence that ceasing consumption of the suspect foods will reduce heartburn, some of the studies did show that certain of the foods (such as chocolate and carbonated beverages) can reduce the pressure exerted by the esophageal sphincter, the control valve that keeps the food you've ...

Despite acidity, orange juice could still be a source of foodborne disease

...aks of salmonellosis have been associated with the consumption of unpasteurized orange juice. The sudden appearance of unpasteurized orange juice as a vehicle for Salmonella could be due to a variety of reasons including a greater amount of orange juice consumed and more importation of orange products from coun...

Metal homeostasis research in plants will lead to nutrient-rich food and higher yielding crops

...de suffer from Iron and/or Zinc deficiencies. Food consumption studies suggest that doubling the Iron in rice can increase the Iron intake of the poor by 50 percent. Rice is a staple food in many of the countries with widespread Iron deficiencies in human diets. Guerinot's lab has previously identified the es...

Transgenic goat's milk offers hope for tackling children's intestinal disease

... the pigs, the study demonstrates clearly that the consumption of pasteurized goat's milk containing human lysozyme can impact the bacterial makeup of the digestive tract in these two distinct animal models," Maga said. "It is likely that the differences observed in the two species were due to the fact that goat...

DOE publishes research roadmap for developing cleaner fuels

... displacing 30 percent of 2004 transportation fuel consumption with biofuels by 2030. This goal was set in response to the President's Advanced Energy Initiative. The roadmap identifies the research required for overcoming challenges to the large-scale production of cellulosic ethanol to help meet this goal, i...
