Scientists fed the tomatoes to mice that lacked the ability to remove low-density lipoprotein (LDL or bad cholesterol) from their blood and readily developed inflammation and atherosclerosis when consuming a high-fat diet.
The researchers found that mice that ate the peptide-enhanced tomatoes which accounted for 2. 2 percent of their Western-style high-fat diet had significantly lower levels of inflammation;

Unchecked the pest burrows into potato roots to feed obstructing nutrients and causing stunted growth wilted leaves and other symptoms that can eventually kill the plant.
Now however U s. Department of agriculture (USDA) and cooperating scientists are evaluating new ways to control G. pallida using naturally occurring chemicals called egg-hatching factors.
According to lead scientist Roy Navarre with USDA's Agricultural research service (ARS) the egg-hatching factors are exuded actually chemicals from the roots of potato and certain other solanaceous plants into surrounding soil.
There the chemicals stimulate G. pallida eggs to hatch Normally this helps ensure the survival of emerging juvenile nematodes.
But Navarre's approach calls for using the chemicals to trick the eggs into hatching
However the eggs are encased in cysts that can resist fumigation according to Navarre who works at the ARS Vegetable and Forage Crops Research Laboratory in Prosser Wash.
He is exploring two approaches to force the eggs to hatch in the absence of a host:

#Bees get a buzz from flower nectar containing caffeineyou may need a cup of coffee to kick start the day
but it seems honeybees also get their buzz from drinking flower nectar containing caffeine. Publishing in Science researchers have shown that caffeine improves a honeybee's memory
In tests honeybees feeding on a sugar solution containing caffeine which occurs naturally in the nectar of coffee
and citrus flowers were three times more likely to remember a flower's scent than those feeding on just sugar.
Study leader Dr Geraldine Wright Reader in Neuroethology at Newcastle University explained that the effect of caffeine benefits both the honeybee and the plant:
In turn bees that have fed on caffeine-laced nectar are laden with coffee pollen and these bees search for other coffee plants to find more nectar leading to better pollination.
So caffeine in nectar is likely to improve the bee's foraging prowess while providing the plant with a more faithful pollinator.
In the study researchers found that the nectar of Citrus and Coffea species often contained low doses of caffeine.
They included'robusta'coffee species mainly used to produce freeze-dried coffee and'arabica'used for espresso and filter coffee.
so we were surprised to find it in the nectar. However it occurs at a dose that's too low for the bees to taste
Typically the nectar in the flower of a coffee plant contains almost as much caffeine as a cup of instant coffee.
Dr Julie Mustard a contributor to the study from Arizona State university explains further: Although human and honeybee brains obviously have lots of differences
Phytase breaks down phytic acid and helps pigs digest more of the nutrient. The phytase enzyme has a hefty price tag for farmers
or destroyed when farmers mix feed. The Enviropig was created to solve this problem. The transgenic pig synthesizes phytase in its salivary glands eliminating the need for additional supplements or enzymes in the feed.
By digesting more phosphorus the Enviropig also produces less phosphorus in its waste. The enzyme is secreted in the saliva
and functions in a similar fashion to that of phytase included in the diet said Dr. Cecil Forsberg Professor Emeritus Department of Molecular
Though no studies indicate a food safety risk from genetically modified Enviropig pork meat from the Enviropig is not yet available for human consumption.

#Pancakes with a side of math: A physiological model for sap exudation in maple treesfor many of us maple syrup is an essential part of breakfast--a staple accompaniment to pancakes
and waffles--but rarely do we think about the complicated and little-understood physiological aspects of syrup production.
Each spring maple growers in temperate regions around the world collect sap from sugar maple trees
which is one of the first steps in producing this delicious condiment. However the mechanisms behind sap exudation--processes that trigger pressure differences causing sap to flow--in maple trees are a topic of much debate.
Sugars are produced in the leaves of the maple tree by photosynthesis with the help of absorbed water carbon dioxide
In the period between this dormant state and the active growing season (during cold nights with below-freezing temperatures followed by mild warm days with above-freezing conditions) the stored starch is converted into sugar
Osmotic pressure which exists due to differences in sugar concentration between different components of the vascular tissue helps maintain stable gas bubbles
and appreciate the opportunity to interact regularly with maple syrup producers. These are people that come from a surprising variety of backgrounds ranging from farmers to retired teachers to construction company owners including very few scientists
Nonetheless we find that maple syrup producers have a real enthusiasm for our work and are excited by the potential for mathematics to contribute to their understanding of very practical problems for the industry.

Results from the study show that the labelling of game meat in South africa is very poor with different species being substituted almost 80%of the time.
In South africa game meat biltong (air dried strips) is big business with over 10000 wildlife farms

Coprolites (preserved fecal material) provide the best direct evidence of prehistoric diet. Among 62 coprolites analyzed of all types--34 human 16 domesticated dog and others from various animals--43 (or 69 percent) contained maize starch grains phytoliths
Coprolites also showed that fish mostly anchovies did provide the primary protein in the diet but not the calories.
