Purdue scientists may have found key to halting spinal cord damage

...rested in." Further research will be necessary to determine how great a role acrolein actually plays in the process of secondary spinal cord damage, but Shi said that once this role is clarified, drugs that counter acrolein's effects could join the other approaches to treating spinal cord injury under develop...

Environmental chemical cocktail may sabotage sperm

...at further investigations should be carried out to determine whether such environmental compounds might contribute to a decrease in human fertility. Other scientists have investigated the negative impact of environmental chemicals on testis function, resulting in reduced numbers of sperm being produced, but th...

Study: Harmless virus kills some cancers

...hough we suspect it is, more studies are needed to determine if the mechanism through which AAV2 destroys cancer cells is the same." Scientists often refer to cancer cells as deregulated, meaning they are no longer acting or communicating like normal, healthy cells. It appears that AAV2 is able to recognize c...

Can our genes tell the story of our divergence?

...nism to avoid cancer. Future studies will have to determine whether these explanations - of an evolutionary arms race - prove plausible. We're a long way from understanding why we're so different from our closest primate cousins, but this study provides plenty of tools, and hypotheses, to mine the tiny differ...

Why are coyotes getting more aggressive?

... to fear humans without harming them. "We need to determine what people are doing, for example, to encourage coyotes into their yards, such as feeding dogs or cats outdoors and leaving the dishes out or leaving animals out at night," says Curtis. The DEC estimates that 20,000-30,000 coyotes make the Empire S...
