A controversial decision in 2011 to blow up Mississippi River levees reduced the risk of flooding in a city upstream, lowering the height of the rain-swollen river just before it reached its peak, according to a newly published computer modeling analysis led by UC Irvine scientists.

The work focused on a Missouri agricultural area called the New Madrid Floodway that was inundated when the levees were detonated. The researchers found that the region would have flooded anyway if the river had been allowed to overtop the levee banks. And separate modeling showed that the resulting damage to crops and buildings would have been similar either way, though the detonations did shift the damage zone toward Missouri and away from Illinois and Kentucky.

Are humans born with the ability to solve problems or is it something we learn along the way? A research group at the Department of Physics and Astronomy, Aarhus University, is working to find answers to this question.

The research group has developed a computer game called Quantum Moves, which has been played 400,000 times by ordinary people. This has provided unique and deep insight into the human brain's ability to solve problems. The game involves moving atoms around on the screen and scoring points by finding the best way to do so.

If kidney cancer is diagnosed early -- before it spreads -- 80 percent of patients survive. However, finding it early has been among the disease's greatest challenges.

Now, researchers at Washington University School of Medicine in St. Louis have developed a noninvasive method to screen for kidney cancer that involves measuring the presence of proteins in the urine.

The findings are reported March 19 in the journal JAMA Oncology.

The researchers found that the protein biomarkers were more than 95 percent accurate in identifying early-stage kidney cancers. In addition, there were no false positives caused by non-cancerous kidney disease.

"These biomarkers are very sensitive and specific to kidney cancer," said senior author Evan D. Kharasch, MD, PhD.

Scientists have turned to the opossum to develop a promising new and inexpensive antidote for poisonous snake bites. They predict it could save thousands of lives worldwide without the side effects of current treatments.

Worldwide, an estimated 421,000 cases of poisonous snake bites and 20,000 deaths from these bites occur yearly, according to the International Society on Toxicology.

The place of religions and belief systems, especially Christianity, in the school curriculum is a sensitive issue provoking much discussion and debate in Australia.

The issue came to head in Britain last year with what has been titled the “Trojan Horse affair”. A small number of Islamic schools were investigated about the types of values being taught. The investigations led to Prime Minister David Cameron arguing that all schools must teach what it means to be British.

Scientists at the University of Cambridge have successfully created 'mini-lungs' using stem cells derived from skin cells of patients with cystic fibrosis, and have shown that these can be used to test potential new drugs for this debilitating lung disease.

The research is one of a number of studies that have used stem cells - the body's master cells - to grow 'organoids', 3D clusters of cells that mimic the behaviour and function of specific organs within the body. Other recent examples have been 'mini-brains' to study Alzheimer's disease and 'mini-livers' to model liver disease. Scientists use the technique to model how diseases occur and to screen for potential drugs; they are an alternative to the use of animals in research.
