three apples

An apple a day could keep obesity away

Apples, especially Granny Smiths, promote friendly bacteria

Apples, especially Granny Smith apples, may help prevent disorders associated with obesity, new research published in the journal Food Chemistry says. “We know that, in general, apples are a good source of these non-digestible compounds but there are differences in varieties,” said Washington State University food scientist Giuliana Noratto, the study’s lead researcher, in a

Even just a little dairy is good for you: researchers

Taiwanese who eat no dairy have higher blood pressure than those who do


A little dairy food daily, even for those who haven’t traditionally consumed it, may reduce the risk of heart disease or stroke, say researchers at Australia’s Monash University. A study of nearly 4,000 Taiwanese was led by Professor Mark Wahlqvist. “In a dominantly Chinese food culture, unaccustomed to dairy foods, consuming them up to seven

Conflicts threaten plant genetic resources

Highest concentration of important wild crop relatives 
is in Syria and Lebanon

Future crop-breeding improvements could be hampered by conflict in the world’s war zones, say researchers from the University of Birmingham in the U.K. Many of today’s most important crops evolved from wild ancestors in the “Fertile Crescent” of the Middle East, arcing around the Arabian desert from Jordan, Palestine, Israel, Syria, Lebanon, Turkey and ending

Possibilities include bananas with more vitamin A or apples that don’t brown when cut.

Genetically edited, not genetically modified?

Avoiding introduction of genes from other organisms 
could alleviate consumer concerns

Recent advances that allow the precise editing of genomes now raise the possibility that fruit and other crops might be genetically improved without the need to introduce foreign genes, according to researchers writing in the Cell Press publication Trends in Biotechnology on Aug. 13. With awareness of what makes these biotechnologies new and different, genetically

Drought causes land to rise like uncoiled spring

Scientists used GPS technology to track uplift from 
recent massive loss of water

The severe drought gripping the western United States in recent years is changing the landscape well beyond localized effects of water restrictions and browning lawns. Scientists at Scripps Institution of Oceanography at UC San Diego have now discovered that the growing, broad-scale loss of water is causing the entire western U.S. to rise up like

Tire makers are turning dandelions into rubber

Dutch biologist Ingrid van der Meer often meets with disbelief when she talks about her work on dandelions and how it could secure the future of road transport. The reaction is understandable, given most people regard the yellow flowers as pesky intruders in their gardens rather than a promising source of rubber for tires. “People

Population control — just let the males take over

Unlike sterilized males, GM versions are good 
performers but run out of females

Scientists at the University of East Anglia and Oxitec Ltd. in the U.K. say they have a new way to control a damaging crop pest — release males genetically engineered to father only male offspring. The scientists conducted greenhouse research with the Mediterranean fruit fly, which damages 300 types of cultivated and wild fruits, vegetables

Pork council spokesman says incoming 
president might have been talking turkey

The incoming president of the National Pork Producers Council in the U.S. was arrested July 23 when officers at a congressional office building found a loaded 9-mm Ruger handgun in his bag, the Washington Post reports. Ronald William Prestage, 59, who lives in Camden, S.C., was charged with carrying a handgun outside a home or


Horses communicate with their eyes and mobile ears

Horses communicate with their eyes and mobile ears

Study also challenges notion that animals with eyes on the sides of their heads cannot glean 
information from each other

Horses are sensitive to the facial expressions and attention of other horses, including the direction of the eyes and ears. The findings, reported in the Cell Press journal Current Biology on August 4, are a reminder for us humans to look beyond our own limitations and recognize that other species may communicate in ways that

Moose saliva causes rapid decline in toxicity

York University researchers have found a surprisingly effective way to fight against a certain species of toxic grass fungus — moose saliva. Their paper published this month in Biology Letters shows that moose and reindeer saliva slows growth and reduces toxicity of a fungus in red fescue. “Plants have evolved defence mechanisms to protect themselves,
