(12/14/2006) Africa may be able to feed just 25% of its population by 2025 if soil degradation on the continent continues at its current pace, according to a water expert presenting at an upcoming United Nations University (UNU) conference on desertification in Algiers, Algeria. Karl Harmsen, Director of UNU's Ghana-based Institute for Natural Resources in Africa, says that should soil conditions continue to decline in Africa, nearly 75% of the continent could come to rely on some sort of food aid by 2025.
Goodbye to the Baiji
(12/14/2006) After a short illness spurred by pollution, overfishing, boat traffic, and obstructions like dams, the Baiji was declared 'functionally extinct' last night. As a species, the river dolphin found only in China's Yangtze River was 20 million years. The Baiji is survived by other river dolphins, all themselves threatened, in the Ganges, Indus, Amazon, Orinoco, and La Plata rivers. No memorial service will be held.
Mammals may have flown before birds
(12/14/2006) Mammals may have flown before birds according to a fossil discovery by scientists working in China. Working in the Inner Mongolian region of China, a team of Chinese and American scientists discovered a 125 million year fossil that provides evidence that mammals were capable of gliding flight some 70 million years earlier than previously believed.
Forests need good soil to sequester more carbon
(12/14/2006) Soil nutrition is key to helping forests absorb more carbon under elevated CO2 conditions according to new research by scientists with the USDA Forest Service and Duke University. "The researchers found that trees can only increase wood growth from elevated CO2 if there is enough leaf area to support that growth," reported the Southern Research Station of the USDA Forest Service in a statement. "Leaf area, in turn, is limited by soil nutrition; without adequate soil nutrition, trees respond to elevated CO2 by transferring carbon below ground, then recycling it back to the atmospheric through respiration."
Monkey trials for medical research should continue in Britain
(12/13/2006) British scientists support the use of primates in medical research to improve human health and reduce deaths from disease but only if no alternatives are available according to a report by the Academy of Medical Sciences. The report, which examines the scientific basis for recent, current and future use of non-human primates in biological and medical research, comes as a poll by the journal Nature reveals that most researchers have no ethical misgivings about the role of animals in their work.
Circumcision reduces HIV/AIDS infection in men
(12/13/2006) Medical circumcision of men reduces their risk of acquiring HIV during heterosexual intercourse by 53 percent according to a University of Illinois at Chicago study. The results were so compelling researchers stopped the trial early to protect the health of participants. The study's safety board recommended that all men enrolled in the study who remain uncircumcised be offered circumcision.
Tigers can recover given protection, adequate food supplies
(12/13/2006) A new study says that if tigers are protected and have sufficient access to abundant prey, their populations can quickly stabilize. The findings have implications for conservation of the world's largest cat species which is fast-disappearing due to poaching for the animal parts trade.
Yellow Sea biodiversity needs protection says WWF

Asian pollution fuels rain in Australia
(12/12/2006) A new study says that the haze produced by fires in southeast Asia causes increased rainfall in Australia by lowering regional ocean temperatures. Particulate matter in the upper atmosphere has been shown to reflect sunlight, hence lowering temperatures.
President Museveni again moves against Uganda's forests
(12/12/2006) Ugandan president Yoweri Museveni has again taken action against rainforest conservation in Uganda, moving to hand a protected forest reserve over to private agricultural interests intent on clearing trees, according to a report from Reuters.
Who pays for Amazon rainforest conservation?
(12/12/2006) Last Monday, Brazil created the world's largest rainforest protected area in the northern Amazon. Covering more than 15 million hectares (57,915 square miles) -- or an area larger than England -- the network of seven new protected reserves has been met with praise by environmental groups. Instrumental in the development of the conservation project has been an organization that most people wouldn't associate with rainforest conservation but certainly should: the Gordon and Betty Moore Foundation.
ESA seeks to better understand impact of oceans on climate
(12/11/2006) The European Space Agency (ESA) said it is backing two projects that aim to better understand the impact of oceans on climate.
Hotspot conservation will not protect global biodiversity
(12/11/2006) The concept of biological hotspots has served as a fundamental principle guiding conservation efforts over the past generation. A new study, published in the Dec. 15 online edition of the Proceedings of the National Academy of Sciences (PNAS), argues this may be a mistake and that conservation efforts based on hotspots will not effectively preserve biodiversity.
Unknown species of lizard discovered in Borneo
(12/11/2006) A previously unknown species of lizard was discovered in Borneo by Chris Austin, assistant curator of herpetology at Louisiana State University's Museum of Natural Science. Photos and the scientific name of the lizard, which was discovered while Austin was conducting field research in Sarawak, will be unveiled in the March 2007 edition of Journal of Herpetology.
Melting glaciers, not ice sheets, primarily responsible for rising sea levels
(12/11/2006) A new study says that melting glaciers are contributing more to the global rise in sea levels than melting ice sheets in Greenland and Antarctica. Of the estimated 650 billion tons of ice lost to the oceans annually, some 400 billion tons comes from the melting of small glaciers and icecaps, according to Professor Tad Pfeffer of the Institute of Arctic and Alpine Research at the University of Colorado at Boulder. Only 250 billion tons -- or less than 40 percent -- comes from the melting of the Greenland and Antarctic ice sheets.
Global warming could save NASA millions in fuel costs
(12/11/2006) Carbon dioxide emissions produced from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017, according scientists from the National Center for Atmospheric Research (NCAR) and Pennsylvania State University (PSU).

Butterfly biomimicry improves communications technology
(12/11/2006) A new DARPA-sponsored study says that biomimicry of butterfly wings can help researchers build complex photonic integrated circuits to improve communications technology. "By replicating the complex micron- and nanometer-scale photonic structures that help give butterfly wings their color, researchers have demonstrated a new technique that uses biotemplates for fabricating nanoscale structures that could serve as optical waveguides, optical splitters and other building blocks of photonic integrated circuits," stated a release from the Georgia Institute of Technology.
Nuclear war could cause global cooling (i.e. block global warming)
(12/11/2006) Nuclear war would disrupt global climate for at least a decade according to new research presented Dec. 11 at the annual meeting of American Geophysical Union in San Francisco. The research, based on findings from historic volcano eruptions, found that a small-scale, regional nuclear war could produce millions of tons of 'soot' particles that could block solar radiation, in effect, cooling the planet.

4-pound lobster discovered off coast of Madagascar
(12/11/2006) Researchers with the Census of Marine Life discovered a 1.8 kg (4 lb) rock lobster that lives off the coast of Madagascar. Named Palinurus barbarae, the beast is half a meter (one-and-a-half feet) long.
500 species found in census of marine life
(12/11/2006) Some 500 previously unknown species of marine life were discovered during the latest Census of Marine Life (CoML), a research effort involving some 2000 researchers from 80 countries. The discoveries, made during 19 ocean expeditions in 2006, included a gigantic 1-centimeter in diameter single-celled organism in the Nazare Canyon off Portugal, a "blonde-haired" lobster near Easter Island, a "chewing" squid, and a four-pound (1.8 kg) lobster off Madagascar.
UN says man's global warming impact lower than thought
(12/10/2006) When it is released in 2007, the UN Intergovernmental Panel on Climate Change (IPCC) will report that man's impact on global climate is less than previously believed according to a story published in the Sunday edition of the UK-based Telegraph. The Telegraph says that the report will reduce its estimate of man's role in global warming by 25 percent. However, the IPCC will still project global temperatures to climb by 4.5 C druing the next century and rising sea levels, albiet by half the amount -- 17 inches instead of 34 inches by 2100 -- projected by the IPCC's 2001 report. It will also note that atmospheric carbon dioxide levels have continued to climb over the past five years but that the overall human effect on global warming since the industrial revolution has been dampened by cooling caused by particulate matter and aerosol sprays, which accumulate in the upper atmosphere and reflect heat from the sun.
The Vaquita, the world's smallest cetacean, dives toward extinction
(12/10/2006) Accidental death in fishing nets is driving the world's smallest cetacean, the Vaquita (Phocoena sinus), towards extinction, according to a new study published in the current issue of Mammal Review, the official scientific periodical of the Mammal Society.

Ebola kills thousands of gorillas in African park
(12/07/2006) The Ebola virus, a nasty hemorrhagic fever that causes massive organ failure and bleeding, is killing thousands of endangered gorillas across Central African forests according to new research published in the journal Science. While the findings suggests that even in strictly protected wildlife sanctuaries gorillas are not safe, the research provides insight on how to control Ebola outbreaks among wild gorillas (Gorilla gorilla) and chimpanzees (Pan troglodytes).
Past global warming suggests massive temperature shift in our future
(12/07/2006) If past climate change is any indication, Earth could be in store for some significant global warming according to research published in the December 8, 2006, issue of the journal Science. The work suggests that climate change skeptics may be fighting a losing cause. The study, led by Mark Pagani, associate professor of geology and geophysics at Yale, looked at an episode of rapid climate change that occurred some 55 million years ago. Known as the Paleocene-Eocene Thermal Maximum (PETM), the period was marked by a rapid rise in greenhouse gases that heated Earth by roughly 9 F (5 C), in less than 10,000 years. The climate warming caused widespread changes including mass extinction in the world's oceans due to acidification and shifts of plant communities due to changes in rainfall. The era helped set the stage for the "Age of Mammals," which included the first appearance of modern primates.
Biomimicry of native prairie yields more bioenergy than corn ethanol
(12/07/2006) Diverse mixtures of plants that mimic the native prairie ecosystem are a better source of biofuels than corn grain ethanol or soybean biodiesel according to a new paper published in the Dec. 8 issue of the journal Science. Led by David Tilman, a biology professor at the University of Minnesota, the research shows that "mixtures of native perennial grasses and other flowering plants provide more usable energy per acre than corn grain ethanol or soybean biodiesel and are far better for the environment," according to a release from the University of Minnesota.
Bioprospecting links health and biodiversity conservation in Panama
(12/07/2006) The difference between bioprospecting and biopiracy as at times controversial, but a program run by the Smithsonian Tropical Research Institute (STRI) suggests that training professionals in high-biodiversity regions can help bring benefits to local populations while promoting biodiversity conservation. The program, called the International Cooperative Biodiversity Groups (ICBG), is profiled in the December issue of the journal BioScience.

Earthquake prediction, however brief, could save lives
(12/05/2006) Could a few seconds warning of an impending strong earthquake be of practical use in mitigating its effects? Scientists, engineers, and first responders say yes, and now such warnings may be possible. Researchers in Italy have analyzed seismic signals from over 200 moderate to strong earthquakes, ranging from magnitude 4.0 to 7.4, and they conclude that the waves generated in the first few seconds of an earthquake (the primary, or P, waves) carry sufficient information to determine its magnitude and destructive potential.
Temperatures in European Alps at 1,300-year high
(12/05/2006) Temperatures in the European Alps are at the warmest point in 1,300 years according to the head of a European Union climate study.
Switchgrass-based ethanol could cost $1 per gallon, reduce foreign oil dependence
(12/05/2006) Genetic engineering of switchgrass, a native prairie plant, could reduce the price of ethanol to $1 per gallon according to a plant geneticist at the University of Rhode Island.
Brazil creates world's largest rainforest reserve
(12/05/2006) Brazil created the world's largest expanse of protected tropical rainforest in Para, the state where American nun Dorothy Stang was murdered after trying to protect land rights of rural poor. The network of seven new protected areas covers an expanse of 15 million hectares (57,915 square miles) -- or an area larger than England -- and links to existing reserves to form a vast conservation corridor in the northern Amazon, one of the most biodiverse regions on the planet.
Nairobi talks made progress on forest conservation for global warming emissions credits
(12/05/2006) Tropical deforestation is one of the largest sources of human-produced greenhouse gases yet it has no place in existing climate agreements. This has been a point of contention in negotiations as the United States has objected to some developing countries -- notably Brazil and Indonesia -- to be getting an apparent "free ride" on deforestation-related emissions in addition to emissions from fossil fuel sources. Recent negotiations have looked at this issue from a different perspective, one where developing countries would be paid by industrialized countries for reducing their deforestation rates. Globally the payoff could be immense, extending well beyond helping mitigate global warming emissions to safeguard biodiversity and important ecological services. Leading scientists have called such plans a "win-win" scenario for all parties and even the World Bank and U.N. have voiced support for the concept.
Green computing - Dell releases energy-saving server
(12/05/2006) Dell released a premium line of energy-efficient servers that consume considerably less power than regular models, joining a list of firms that offer consumers 'greener' products.
California crop production could plunge due to global warming
(12/05/2006) Higher temperatures could cause a 40 percent drop in some of California's most popular crops by mid-century according to new research in the journal Agricultural and Forest Meteorology. Almonds, walnuts, oranges, avocados and table grape could be especially affected.
Fighting air pollution could feed the hungry in India
(12/05/2006) Reducing human-generated air pollution could create agricultural benefits in India according to research published by University of California scientists in the current online issue of the journal Proceedings of the National Academy of Sciences (PNAS).
Moray eels and groupers hunt together
(12/05/2006) Moray eels and groupers hunt together according to research published in the December 5 issue of PLoS Biology. A team of researchers lead by Redouan Bshary, a biologist at the University of Neuchatel in Switzerland, found that moray eels and groupers practice cooperative hunting in Red Sea coral reefs -- behvaior not before described outside primates and birds. The hunting habits of groupers, which are diurnal (day-active) predators that hunt in open water, are markedly different from moral eels, which are evasive nocturnal hunters that sneak through reef crevices in an attempt to ambush and corner prey. As such prey have distinctly different evasive behvaior when confronted by groupers versus morays.
Another large tsunami could hit Indonesia soon
(12/05/2006) Researchers at the University of Southern California (USC) and California Institute of Technology (Caltech) say that the Indonesian island of Sumatra could be due for another large tsunami like the one that devastated the island on December 26, 2004. Their research is published in the December 4 Proceedings of the National Academy of Sciences.
Logging roads lead to disease, social breakdown in Ecuador rainforest communities
(12/04/2006) Logging roads are linked to increased incidence of diarrheal disease and new social problems among communities along the Ecuadorian coast, according to a new study published in the Online Early Edition of Proceedings of the National Academy of Sciences (PNAS) for the week of December 4-8, 2006. Lead by Joseph Eisenberg, assistant professor of epidemiology at the University of Michigan School of Public Health, an international team of researchers examined diarrheal infections and social networks in 21 villages recently connected to a new government-constructed road network in the Choco rainforest of coastal Ecuador. They found that the new roads bring colonists to the region and allow villagers to travel more easily between villages and larger cities. Increased mobility increases the spread of bacteria, viruses and parasites according to Eisenberg.
Neanderthal life was miserable suggests new evidence
(12/04/2006) New analysis of 43,000-year-old samples of Neanderthal remains from Spain's Iberian Peninsula suggest our relatives eked out a meager existence, possibly supplemented by cannibalism. The results are published in the early online edition of the Proceedings of the National Academy of Sciences (PNAS) for the week of December 4-8, 2006.
