  • Vitamin C may stop leukemia from progressing
    New research finds that high-dose vitamin C can genetically 'reprogram' leukemic cells to mature and die normally, instead of replicating to cause cancer. ... Read more...

  • Jumping genes made us human, but can they cause disease?
    Ancient bacteria and viruses left their traces all over our DNA. This may have given us an edge in our quest to become human, but it comes at a price. ... Read more...

  • Should we transplant pig organs into humans? | Chas Newkey-Burden and Susan Watts
    With a breakthrough in gene editing, the prospect of breeding animals to harvest their organs looms. Chas Newkey-Burden and Susan Watts go head to headPigs are intelligent creatures with social instincts and emotional depth. We are so closely related to them that their hearts can replace our own. But what sort of person would kill a relative for spare parts? Related: Gene editing to remove viruses brings transplant organs from pigs a step closer ... Read more...

  • Ethnicity is not something dictated by people’s genes | Letters
    John Collis on the limitations of DNA testing, Peter McKenna on the Romans and race, and Alun Thomas on West Midlands historyDNA testing to determine people’s origins (DNA uncovers villagers’ exotic heritage, 11 August) should come with a major health warning as interpretations are based on false scientific methodologies.First, there is a confusion between two types of data. Our DNA is what we inherit from our parents and, until recently at least, could not be ... Read more...

  • Last minute guide to the total solar eclipse
    In exactly a week, a total eclipse will be visible, spanning along a narrow path through the United States. In readiness for the event on 21 August 2017, we asked physicist and eclipse-chaser professor Frank Close eight questions about eclipses, and how to watch them. What is a solar eclipse? The moon is 400 times smaller than the sun, but it’s also 400 times closer to earth, which means that remarkably, the two bodies appear ... Read more...

  • Ecosystem-based mitigation and adaptation
    Payments for ecosystem services (PES), also known as payments for environmental services (or benefits), are incentives offered to farmers or landowners in compensation for proper land-management that provides ecological services. Among these benefits we can mention conserving animal and plant species, protecting hydric resources, conserving natural scenery, and storing carbon. Costa Rica is a pioneer in PES schemes. Since 1997 approximately one million hectares of forest have been part of these ‘payments for ecosystem services’ ... Read more...

  • DNA testing for immigration and family reunification?
    During the past decade, immigrants accounted for 47% of the increase in the US workforce and 70% in Europe. Family reunification is one of the main forms of immigration in many countries. However, in recent times, immigration has become increasingly regulated with many countries encouraging stricter vetting measures. In this climate, countries’ laws and policies applicable to family reunification seek a balance between an individual’s right to a family life and a country’s right to ... Read more...
