Scientist warns of threat to last stronghold of endangered turtle

...st Africa, the focus of this study. With fishing yields decreasing in European seas the EU has struck up a number of agreements with African nations to fish their waters. Amazingly, most EU fishing concessions don't even incorporate compulsory bycatch monitoring programmes. Scientists from the Universit...

New lab technique churns out fungus' potential cancer fighter

... complicated chemical synthesis process that still yields only a minute amount," he says. "Now, after five years of effort, we've worked out a process that lets researchers finally produce enough rasfonin to really start investigating how it functions, and how we might harness it to fight cancer." In 2000,...

New genetic test for breast cancer

...tient will benefit from chemotherapy. "This test yields what is called a recurrence score. For about 55 percent of women, the recurrence score is greater than 25 or less than 11. In these cases, the test clearly indicates the most effective therapy: a combination of chemotherapy and hormones for women ...

The brain's executive is an 'event planner'

...n is significant, said the researchers, because it yields new basic insight into a central function of behavioral planning in this higher brain region, called the lateral prefrontal cortex (PFC). The researchers, led by Hajime Mushiake of Tohoku University School of Medicine, reported their findings in th...

Interfering RNA silences genes in 'slippery' immune cells

...netic sequences to regulate the gene activity that yields an siRNA. After the researchers tested a variety of SECs to determine which is the most effective, they inserted the desired SEC into a vector, a biological agent that inserts itself into a target cell's nucleus more efficiently than an unaccompanied...

Plant diseases threaten chocolate production worldwide

...oetz. "In this region, either disease could reduce yields by an additional one million more metric tons per year," he said. New insights and current research on cacao diseases, as well as resistance to and management of the diseases, will be addressed during the Cacao Diseases: Important Threats to Chocol...

Salk scientists untangle steroid hormone signaling in plants

Carrière suggests that yields were similar across cotton types because the additional insecticide applications on the non-Bt fields cut down on the damage from whiteflies and western tarnished plant bugs. To see what factors affected insect biodiversity in the cotton fields, th...

Fight weeds with plant pathogens

...o agricultural productivity. Weeds can reduce crop yields by as much as 12 percent (causing up to $32 billion in losses), based on the potential value of all U.S. crops of approximately $267 billion/year. Weeds also pose serious ecological problems. Invasive weeds are capable of altering ecosystem processes...
