An ancient human skull and a jawbone found a few meters apart in a cave in northern Laos add to the evidence that early modern humans were physically quite diverse, researchers report in PLOS ONE.
An experimental drug rapidly shrinks most tumors in a mouse model of human breast cancer, researchers report in the Proceedings of the National Academy of Sciences. When mice were treated with the experimental drug, BHPI, “the tumors immediately stopped growing and began shrinking rapidly,” said University of Illinois biochemistry professor and senior author David Shapiro. “In just 10 days, 48 out of the 52 tumors stopped growing, and most shrank 30 to 50 percent.”
Using high-performance computing and genetic engineering to boost the photosynthetic efficiency of plants offers the best hope of increasing crop yields enough to feed a planet expected to have 9.5 billion people on it by 2050, researchers report in the journal Cell.
A genetic study of papaya sex chromosomes reveals that the hermaphrodite version of the plant, which is of most use to growers, arose as a result of human selection, most likely by the ancient Maya some 4,000 years ago.
Subsistence farmers in Africa, the Americas and the Caribbean are learning how to construct raised planting beds and install drip irrigation systems to boost their agricultural productivity, conserve water and perhaps even halt the rapid advance of desertification in some drought-prone regions.
Two University of Illinois professors have been elected fellows of the American Academy of Microbiology. Steven Blanke and Bryan White are among the 79 microbiologists chosen by their peers for this honor.
