Are humans causing cancer in wild animals?

Mon, 21/05/2018 - 19:38
As humans, we know that some of our activities can cause cancer to develop in our bodies. Smoking, poor diets, pollution, chemicals used as additives in food and personal hygiene products, and even too much sun can contribute to an increased risk of cancer. But, are human activities also causing cancer in wild animals? Researchers think so and are urgently calling for research into this topic.

Mediterranean diet may blunt air pollution's ill health effects

Mon, 21/05/2018 - 18:18
Eating a Mediterranean diet may protect people from some of the harm of long-term exposure to air pollution, and reduce their risk of dying from heart attacks, stroke and other causes of death, according to new research.

Battling bubbles: How plants protect themselves from killer fungus

Thu, 17/05/2018 - 19:25
In the battle between plants and pathogens, molecules called small RNAs are coveted weapons used by both invaders and defenders. Researchers report how plants package and deliver the sRNAs they use to fight back against plant pathogens. The study focused on Botrytis cinerea, a fungus that causes a grey mold disease in strawberries, tomatoes, and almost all fruits, vegetables, and many flowers.

Keep saying yes to fish twice a week for heart health

Thu, 17/05/2018 - 13:18
A new scientific advisory reaffirms the recommendation to eat two servings of fish per week.

For older adults, a better diet may prevent brain shrinkage

Wed, 16/05/2018 - 21:25
People who eat a diet rich in vegetables, fruit, nuts and fish may have bigger brains, according to a new study.

Beef peptides block bitter tastes

Wed, 16/05/2018 - 17:37
From burgers to steaks, beef has a long history of being a delicious part of dinner. But what if that pleasant experience of eating beef could extend beyond the dinner plate? Now, one group reports that beef protein, when broken down into peptides, can block bitter taste receptors on the tongue. Such peptides could someday be used to make other foods and even medicines taste better.

A high-fiber diet protects mice against the flu virus

Tue, 15/05/2018 - 16:38
Dietary fiber increases survival in influenza-infected mice by setting the immune system at a healthy level of responsiveness, according to a preclinical study published May 15 in the journal Immunity. A high-fiber diet blunts harmful, excessive immune responses in the lungs while boosting antiviral immunity by activating T cells. These dual benefits were mediated by changes in the composition of gut bacteria.

Wasps drum to alert one another of food nearby

Tue, 15/05/2018 - 16:35
New research shows wasps have their own way of communicating to each other about mealtimes -- drumming on their gaster (or abdomen) to let each other know that there's food nearby. For nearly five decades, researchers thought the gastral drumming was a signal of hunger. These findings are the first evidence that wasps have complex communication about food, just as ants, bees, termites, and other social insects.

Increased overweight in children of mothers who drank coffee while pregnant

Fri, 11/05/2018 - 15:23
A new study shows that even moderate coffee consumption during pregnancy, one to two cups per day, is related to a risk of overweight or obesity in school age children. It has not been clearly shown if caffeine is the direct cause of the overweight, but the relationship, alone, has caused researchers to encourage increased caution.

Food-carrying ants use collective problem solving to get through or around obstacles

Thu, 10/05/2018 - 20:02
Ants working together to carry a large piece of food get around obstacles by switching between two types of motion: one that favors squeezing the morsel through a hole and another to seek a path around the barrier.

What gives bees their sweet tooth?

Thu, 10/05/2018 - 20:00
Scientists have discovered bees linger on a flower, emptying it of nectar, because they have sugar-sensing taste neurons which work together to prolong the pleasure of the sweetness.

Dietary seaweed used to manipulate gut bacteria in mice

Wed, 09/05/2018 - 18:54
Scientists working with laboratory mice have shown that it's possible to favor the engraftment of one gut bacterial strain over others by manipulating the mice's diet. The researchers also have shown it's possible to control how much a bacterium grows in the intestine by calibrating the amount of a specific carbohydrate in each mouse's water or food.

Infant growth patterns affected by type of protein consumed

Wed, 09/05/2018 - 15:50
A new study has determined that protein intake from solid foods has a significant impact on infant growth during the first year of life. The study tested whether dairy-based or meat-based protein in an infant's diet contributed to growth and weight gain.

Shiga toxin-producing E. coli found in food

Wed, 09/05/2018 - 15:49
Escherichia coli (E. coli) is a germ that occurs naturally in the gut of mammals and birds, as well as in the human intestinal flora. However, certain E. coli types can cause severe diarrhea in humans. These virulent E. coli types include Shiga toxin-producing E. coli (STEC), also known as Verotoxin-producing E. coli (VTEC).

Machine learning flags emerging pathogens

Tue, 08/05/2018 - 19:50
A new machine learning tool that can detect whether emerging strains of the bacterium, Salmonella are more likely to cause dangerous bloodstream infections rather than food poisoning has been developed. The tool greatly speeds up the process for identifying the genetic changes underlying new invasive types of Salmonella that are of public health concern.

Emojis used to develop a modern face scale for product testing

Tue, 08/05/2018 - 16:17
A new study finds that emojis are a viable alternative to words when it comes to accurately measuring how kids feel about food, products and other experiences. With that discovery, researchers developed an emoji scale that may help companies better test products in non-Western cultures.

Symptoms of osteoarthritis may be lessened with simple changes to the diet

Tue, 08/05/2018 - 14:49
One gram of fish oil a day could help reduce the pain of patients with osteoarthritis, a new study finds. Researchers also found that a reduction of weight for overweight and obese patients and the introduction of exercise tailored to mobility could also help ease the symptoms of osteoarthritis.

Importing food damages domestic environment

Mon, 07/05/2018 - 20:30
Trees falling as fragile forests become cropland is a visual shorthand for the environmental costs exporting countries pay to meet lucrative global demands for food. Yet a new study reveals a counterintuitive truth: Importing food also damages homeland ecology. In this week's Proceedings of the National Academy of Sciences, researchers at Michigan State University and their colleagues show that the decisions domestic farmers must make as imported food changes the crop market can damage the environment.

Genetics help make a weed a weed

Mon, 07/05/2018 - 16:18
New research finds that the success of weedy and invasive plants like the Jerusalem artichoke lies in their genes.

Eggs not linked to cardiovascular risk, despite conflicting advice

Mon, 07/05/2018 - 12:42
Eating up to 12 eggs a week does not increase cardiovascular risk factors in people with pre-diabetes or type 2 diabetes, new research finds -- despite conflicting dietary advice continuing around the world.
