One of the ultimate goals of Mars exploration is to bring samples from the surface to Earth, especially those that could be examined for evidence of life on the Red Planet.
Such an undertaking would be expensive and the samples risk contamination during their journey to Earth. So, one option ... Read More
A Biosecurity Research Institute study has found important results in the fight against Zika virus: Culex mosquitoes do not appear to transmit Zika virus.
Researchers at Kansas State University's Biosecurity Research Institute studied Culex species mosquitoes from across the country, includin... Read More
For the past several decades, farmers have been abandoning their plows in favor of a practice known as no-till agriculture. Today, about one-third of U.S. farmers are no longer tilling their fields, and still more are practicing conservation tillage—using equipment that only disturbs the soil to... Read More
U.S. public health officials are bracing for a wave of babies with severe Zika-related birth defects. The latest official numbers suggest 808 pregnant women in the U.S. appear to have been infected with Zika. Yet doctors are also steeling themselves for the possibility of birth abnormalities in ...

For decades a deadly fungus has been slaughtering amphibians around the world, driving many to the brink of extinction or even beyond.
But now one frog’s recovery shows that, with a little luck and habitat preservation, some amphibians may be able to evolve resistance to the fungus.
In lab... Read More
A team of scientists has created a genetic map of all possible receptors the human immune system might generate—also known as the immunome.
The project involved a mind-boggling data set.
“If we were on a treasure hunt, where the cure to many illnesses is the buried treasure, then we’ve jus... Read More
A team of Chinese investigators has discovered a gene for resistance to β-lactamase antibiotics, in the pathogenic marine bacterium, Vibrio parahaemolyticus. The β-lactamase gene, blaVEB-2, has never before been found in V. parahaemolyticus, and in fact, has been found almost exclusively in non-... Read More
