New technology eliminates plant toxins

A team of researchers from the University of Copenhagen have developed a method to hinder unwanted toxins from entering the edible parts of plants such as the oilseed rape, which will make it suitable for animal feed.

Out of Europe

Researchers show that access to clean water might not reduce the incidence of dysentry as a country becomes more developed. As countries become more industrialized, and improve health, lifestyle and access to clean water, the numbers of infections with dysentery-causing Shigella flexneri decline. However, incidence of another form of the dysentery-causing bacterium, Shigella sonnei, increase with...

Researchers discover new mechanism behind resistance to cancer treatment

Developing resistance to chemotherapy is a nearly universal consequence for cancer patients with solid tumors -- such as those of the breast, prostate, lung and colon -- that have metastasized, or spread, throughout the body. A team of scientists led by Fred Hutchinson Cancer Research Center has discovered a key factor that drives this drug resistance -- information that ultimately may be used to...

White blood cells mediate insulin resistance

Researchers at the University of California, San Diego School of Medicine say neutrophils, an abundant type of white blood cell typically tasked with attacking bacteria and other foreign invaders, also plays an unexpected role in mediating insulin resistance -- the central characteristic of type 2 diabetes, which afflicts an estimated 26 million Americans.

New study links current events to climate change

The relentless, weather-gone-crazy type of heat that has blistered the United States and other parts of the world in recent years is so rare that it can't be anything but man-made global warming, says a new statistical analysis from a top government...

Love and other animals

Like the male antechinus mouse, the oversexed often fail to find loveAt just 11 months, the male antechinus mouse reaches sexual maturity. He searches his territory every night, hoping to satisfy his voracious sexual appetite. The escalating hormones lead him to 12-hour sexual encounters and mating sprees that span up to four days (all without stopping to eat, drink or rest with his...

New study ties global warming to recent year heat

An analysis by a top government scientist says the extreme heat and drought seen in the U.S., Europe and other regions in recent years must be global warming. Specifically the study by NASA scientist James Hansen blames climate change for last year's drought in Texas and Oklahoma, the 2010 heat wave in Russia and the 2003 European heat wave that led to tens of thousands of...
