Historical records are often used to learn about ancestry but a new approach, using genetics, is currently being applied. In a recent study, published in PLOS Genetics, scientists from the Stanford University School of Medicine and the University of Miami Miller School of Medicine compared patterns of genetic variation found in populations in and around the Caribbean. They were able to discern an influx of European genes into the native population that occurred within a generation of...

Mixe-Zoquean Cultures May Have Had Multiple Culinary Uses For Chili Peppers
2013-11-14 10:22:30

Public Library of Science Chili peppers may have been used to make spicy beverages thousands of years ago in Mexico, according to new research published November 13 in the open-access journal PLOS ONE by Terry Powis at Kennesaw State University and colleagues from other institutions. Capsicum species are usually referred to as chili peppers, and their uses are well known in the history of Spain and Portugal. There are relatively few sites in Mesoamerica, Central America, and South...

Mechanism Through Which The Expression Of Genes Is Controlled Revealed
2013-10-30 08:58:05

Public Library of Science A new study by Weill Cornell Medical College scientists reveals a mechanism through which the expression of genes is controlled – a finding that highlights genetic mutations that can impair the timing of gene expression. Such mutations can affect the co-ordination of key events that are required for stepwise development of an organism, and can also give rise to cancer by turning on genes at the wrong time. The study, published October 29 in the open access...

Living Stone Plant Employs New Way To Improve Underground Photosynthesis
2013-10-24 08:33:07

Public Library of Science A unique plant that lives underground uses multiple mechanisms to boost photosynthesis and offers new insights into how plants adapt to extreme conditions, according to new research published October 23 in the open-access journal PLOS ONE, by Katie Field and colleagues at the University of Sheffield and other institutions. Lithops are a type of South African "living stone," a mostly underground plant that lives in extremely dry conditions. This underground life...

Are scientists any good at judging the importance of the scientific work of others? According to a study published 8 October in the open access journal PLOS Biology (with an accompanying editorial), scientists are unreliable judges of the importance of fellow researchers' published papers. The article's lead author, Professor Adam Eyre-Walker of the University of Sussex, says: "Scientists are probably the best judges of science, but they are pretty bad at it." Prof. Eyre-Walker and Dr...

Increasing Crop Yield, Decreasing Food Consumption Needed To Slow, Reverse Deforestation
2013-10-09 09:09:27

Public Library of Science Feeding a growing global population while also slowing or reversing global deforestation may only be possible if agricultural yields rise and/or per capita food consumption declines over the next century, according to historic global food consumption and land use trends. Published October 9, 2013, in the open-access journal PLOS ONE by Chris Pagnutti, Chris Bauch, and Madhur Anand from the University of Guelph, this research underscores the long-term challenge of...

Higher measures of aerobic fitness linked to better recall of learned information Physical fitness can boost learning and memory in children, particularly when initial learning on a task is more challenging, according to research published September 11 in the open access journal PLOS ONE by Lauren Raine and colleagues from the University of Illinois at Urbana-Champaign. Forty-eight children aged nine to ten were asked to memorize names and locations on a fictitious map, either only by...

Public Library of Science Humpback whale populations are on the rise in the coastal fjords of British Columbia, doubling in size from 2004 to 2011, according to results published September 18 in the open access journal PLOS ONE by Erin Ashe from the Sea Mammal Research Unit at the University of St. Andrews and colleagues from other institutions. Researchers estimated abundance of Pacific humpback whales (Megaptera novaeangliae) using photo-identification surveillance of identifiable...

Tarantula Venom Protein May Serve As Bioinsecticide For Cotton Crop Pests
2013-09-12 10:10:21

Public Library of Science Spider venoms are usually toxic when injected into prey, but a new protein discovered in the venom of Australian tarantulas can also kill prey insects that consume the venom orally. The protein is strongly insecticidal to the cotton bollworm, an important agricultural pest, according to research published September 11 in the open access journal PLOS ONE by Glenn King and Maggie Hardy from the Institute of Molecular Bioscience at the University of Queensland,...
