Pollution detector designed to protect heritage sites
November 11, 2013 09:06 AM - Joshua Howgego, SciDevNet
A simple detector could help conservators at World Heritage sites in the developing world understand and protect against atmospheric pollutants that can damage valuable artifacts. The pollutant-measuring device has been prototyped by Henoc Agbota, an engineer at University College London, United Kingdom, and presented last week (30 October) at a conference marking the end of a five-year funding programme for heritage science run from the university.
Exploration urged to discover new rice species
November 8, 2013 08:50 AM - Lotuslei Dimagiba, SciDevNet
More exploration is needed to discover new wild varieties of rice, before they are lost to science forever, heard the 7th International Rice Genetics Symposium held this week (5-8 November) in Manila, the Philippines. There are still many unexplored places and a danger of losing undiscovered rice species that "might be very important for future rice" breakthroughs, said Robert Henry, director of the research institute Queensland Alliance for Agriculture and Food Innovation. Henry, who was speaking at the symposium organized by the International Rice Research Institute (IRRI), said a lot of biodiversity is being lost because of the rapid pace of development. This means exploration is in a race with this biodiversity loss.
Scientists start to tap marine microbes for biotech use
November 5, 2013 10:36 AM - Michelle Dobrovolny, SciDevNet
[PARIS] The hot, brackish waters of French Polynesia’s lagoons in the Pacific could harbour microbes with huge commercial potential, including for drug creation or to produce alternatives to plastics, say researchers. The extreme conditions found in some Polynesian aquatic ecosystems, which are often characterised by high temperatures and salinity, mean that unique marine bacteria have evolved there.
Nitrogen fixation helps double some African farm yields
November 5, 2013 08:59 AM - Joris Tielens, SciDevNet
A large-scale research and development project has shown that giving farmers resources and advice on nitrogen fixation through legume plants can double yields and boost incomes in Africa. But not all farmers are benefiting from this practice due to a lack of access to inputs, such as fertilizers says Ken Giller, the leader of the N2Africa project, as a second phase to widen access to the initiative is announced with US$25.3 million funding from the Bill & Melinda Gates Foundation for the next five years.
Impacts of climate change on soils
November 1, 2013 06:13 AM - Ollivier Girard/CIFOR, SciDevNet
The increased aridity expected this century as a result of climate change may disrupt the balance of key soil nutrients with a knock-on effect on soil fertility threatening livelihoods of more than two billion people, a study finds. The drop in nitrogen and carbon concentrations that occurs as soils become dryer could have serious effects on ecosystem services such as food production, carbon storage and biodiversity, according to the Nature paper published today.
Climate change to disrupt soil nutrients in drylands

Kazakhstan nuclear test site clean up success
October 27, 2013 08:32 AM - Paul Lowe / Panos, SciDevNet
A Soviet-era nuclear test site in Kazakhstan was cleaned up through a collaborative international project that could provide lessons for tackling other dangerous nuclear sites across the globe, a report reveals. The report, entitled 'Plutonium Mountain', documents how international scientific cooperation was important for securing nuclear waste from the site. It was released in August by the Belfer Center for Science and International Affairs at Harvard University, United States. The Semipalatinsk test site, which spans an area about the size of Belgium, lies in a remote part of eastern Kazakhstan. It embodied the post-Cold War risk of 'loose nukes' -- the threat that terrorists or rogue states could obtain nuclear fissile materials — according to the report.
Lack of nanotech regulations leaves developing world exposed
October 25, 2013 01:18 PM - Lou Del Bello, SciDevNet
Nanotechnology is a promising field, but a lack of regulation means there is uncertainty over the safety of its implementation, particularly in developing countries. This week I received some unexpected insights on nanotechnology and its relationship with industry in different parts of the world.
A ground-breaking, legally-binding global treaty on reducing mercury pollution has been signed by 92 countries. The treaty spells "the beginning of the end of mercury as a threat to human health and the environment", UN Environment Programme (UNEP) executive director Achim Steiner, told a diplomatic meeting in Japan earlier this month (10-11 October) where the treaty was signed. But much work remains to provide the funding and technical and scientific advice needed to implement the treaty, and to expand mercury monitoring capacity worldwide, experts say.
Record temperatures set to reach tropics first
October 10, 2013 03:21 PM - Diane Desotelle, MN Sea Grant, SciDevNet
Tropical regions will be the first to experience unprecedented climate change, leading to significant upheaval for biodiversity and communities, according to a study published in Nature today. Regions near the equator will be subject to mean temperatures hotter than anything experienced on record an average of 15 years before the rest of the world, putting a strain on their rich biodiversity, which is adapted to stable climate conditions, finds the study.
