Scientists poised to win the race against rust disease and beyond

Tue, 20/02/2018 - 22:03
In a race to prevent and control rust disease epidemics, scientists have positioned themselves to better understand how rust fungi infect crops and evolve virulence.

Researchers challenge claims that sugar industry shifted blame to fat

Thu, 15/02/2018 - 19:17
In recent years, high-profile claims in the academic literature and popular press have alleged that the sugar industry paid scientists in the 1960s to play down the link between sugar and heart disease and emphasize instead the dangers of dietary fat. Historians challenge those claims through a careful examination of the evidence.

Eating yogurt may reduce cardiovascular disease risk

Thu, 15/02/2018 - 19:17
A new study suggests that higher yogurt intake is associated with lower cardiovascular disease risk among hypertensive men and women.

Clean plates much more common when we eat at home

Wed, 14/02/2018 - 19:57
When people eat at home, there's typically not much left on their plates - and that means there's likely less going to landfills, according to new research.

Problems with herbicide-resistant weeds become crystal clear

Wed, 14/02/2018 - 14:38
Herbicide-resistant weeds are threatening food security, but researchers are one step closer to a solution after a new discovery. They have now uncovered how penoxsulam, the active ingredient in the world's largest-selling rice herbicide, works.

Graphene on toast, anyone?

Tue, 13/02/2018 - 17:32
The same scientists who introduced laser-induced graphene have enhanced their technique to produce what may become a new class of edible electronics.

Efforts are needed to tap into the potential of nutraceuticals

Tue, 13/02/2018 - 13:44
A growing demand exists for nutraceuticals, which seem to reside in the grey area between pharmaceuticals and food.

Global warming could cause key culinary crops to release seeds prematurely

Mon, 12/02/2018 - 17:12
Climate change is threatening crop yields worldwide, yet little is known about how global warming will confuse normal plant physiology. Researchers now show that higher temperatures accelerate seed dispersal in crop species belonging to the cabbage and mustard plant family, limiting reproductive success, and this effect is mediated by a gene called INDEHISCENT.

Organic food provides significant environmental benefits to plant-rich diets

Fri, 09/02/2018 - 15:07
A study of the diets of 34,000 people confirms that a diet high in fruit and vegetables is better for the planet than one high in animal products. The study also finds that organic food provides significant, additional climate benefits for plant-based diets, but not for diets with only moderate contribution from plant products. This is the first-ever study to look at the environmental impacts of both food choices and farm production systems.

Termites' unique gut 'factory' key to global domination

Thu, 08/02/2018 - 17:09
Termites have achieved ecological dominance and now some ingredients for their success have been determined to lie in their unique gut microbiome 'factories' -- which enable the creatures to eat wood and other material relatively free of competition. New research shows the majority of termite gut microorganisms is not found in any other animals and that they are not only inherited from parents but are also shared across colonies and among distantly related termite species.

Sick bees eat healthier

Wed, 07/02/2018 - 16:01
Scientists have shown that sick bees try to look after themselves by eating healthy food.

Mouse study reveals what happens in the gut after too much fructose

Tue, 06/02/2018 - 19:06
Researchers report that in mice, fructose, a sugar found in fruit, is processed mainly in the small intestine, not in the liver as had previously been suspected. Sugary drinks and processed high-sugar foods overwhelm the small intestine and spill into the liver for processing. Additionally, the authors learned that the ability of the small intestine to process fructose is higher after a meal.

Farmed seafood and livestock stack up differently using alternate feed efficiency measure

Tue, 06/02/2018 - 15:58
A new study found that, contrary to widely held assumptions, farmed fish and shrimp convert protein and calories in feed to edible seafood at rates similar to livestock (i.e., cattle, pigs, and chickens)

Vitamin A in cattle fodder is potentially protecting against cow's milk allergy

Tue, 06/02/2018 - 15:03
Infants can develop an allergy to cow's milk that usually subsides by adulthood but may increase risk for developing other allergic diseases. The allergic reaction can, however, be prevented by two components of cow's milk interacting together, as researchers now describe. Loading of vitamin A metabolite retinoic acid to the important milk protein beta-lactoglobulin in cow's milk can prevent allergic reaction against the protein.

More robust listeria risk assessment by including heat-injured cells

Tue, 06/02/2018 - 14:15
Developing assessment models that more accurately predict the risk of Listeria contamination, particularly with regard to heat-injured cells, will help food manufacturers enhance food safety protocols—and protect consumers from foodborne pathogens.

Even small changes within an ecosystem can have detrimental effects

Thu, 01/02/2018 - 22:33
A mutualistic relationship between species in an ecosystem allows for the ecosystem to thrive, but the lack of this relationship could lead to the collapse of the entire system. New research reveals that interactions between relatively small organisms are crucial to mutualistic relationships in an ecosystem dominated by much larger organisms, including trees and elephants.

Norway rats trade different commodities

Thu, 01/02/2018 - 22:31
Researchers have shown for the first time in an experiment that also non-human animals exchange different kind of favors. Humans commonly trade different commodities, which is considered a core competence of our species. However, this capacity is not exclusively human as Norway rats exchange different commodities, too. They strictly follow the principle "tit for tat" -- even when paying with different currencies, such as grooming or food provisioning.

Central Valley soil emissions a large source of California's nitrogen oxide pollution

Wed, 31/01/2018 - 21:03
A previously unrecognized source of nitrogen oxide is contributing up to about 40 percent of the NOx emissions in California, according to a new study. The study traces the emissions to fertilized soils in the Central Valley region.

The science behind the fizz: How the bubbles make the beverage

Wed, 31/01/2018 - 16:03
From popping a bottle of champagne for a celebration to cracking open a soda while watching the Super Bowl, everyone is familiar with fizz. But little is known about the chemistry behind the bubbles. Now, one group sheds some light on how carbonation can affect the creaminess and smoothness of beverages.

Bananas are some of the worst food waste culprits, study shows

Tue, 30/01/2018 - 14:14
A recent study shows that seven products account for almost half the fruit and vegetables wasted by retailers. Potentially, food waste can be drastically limited by focusing on these products.
