Why don't we know more about Lake Ellsworth? Because it's a frozen lake. Buried under two miles of ice. In Antarctica.

But Northumbria glaciologist Dr John Woodward, together with experts from the British Antarctic Survey and Edinburgh University, will spend five months working in sub zero conditions to unlock some of its secrets and discover what life may exist there.

More than 150 subglacial lakes have been identified in Antarctica, cut off from the outside world by thick caps of ice for tens or even hundreds of thousands of years. Any life forms will have had to adapt to complete darkness, very few nutrients, crushing water pressures and isolation from the atmosphere.

Most people who have tried to install new computer software are happy to know that a common set of default options is available. For many, they will work fine and customization is only required in a few instances, which leads to less technical support, frustration and downtime.

Can that same computer software model work in health care?

In an opinion article in the September 28 issue of the New England Journal of Medicine, lead author Scott D. Halpern, M.D., a fellow in the division of Pulmonary, Allergy and Critical Care Medicine in the University of Pennsylvania Health System, and colleagues, argue that these concepts applied by marketers should also be used by the medical community to benefit patients.

New research from the Max Planck Institute of Evolutionary Anthropology in Leipzig shows that, unlike humans, chimpanzees do not show a willingness to make fair offers and reject unfair ones. The research, conducted by Keith Jensen, Josep Call and Michael Tomasello, used a modification of one of the most widely used and accepted economic tools, the ultimatum game.

In the ultimatum game - developed by Werner Güth, now at the Max Planck Institute for Economics in Jena - one person, the proposer, is given money by an experimenter. That proposer can then divide the "mana from heaven" with a second person, the responder. The responder is not powerless - if he accepts the division, both people take home the offered amounts. But if he rejects it, both get nothing.

That question may be answered as scientists study the recently mapped genetic makeup of a fungus that spawns the worst cereal grains disease known and also can produce toxins potentially fatal to people and livestock.

The fungus, which is especially destructive to wheat and barley, has resulted in an estimated $10 billion in damage to U.S. crops over the past 10 years. The scientists who sequenced the fungus' genes said that the genome will help them discover what makes this particular pathogen so harmful, what triggers the process that spreads the fungus and why various fungi attack specific plants.

University of Utah scientists discovered a strange method of reproduction in primitive plants named cycads: The plants heat up and emit a toxic odor to drive pollen-covered insects out of male cycad cones, and then use a milder odor to draw the bugs into female cones so the plants are pollinated.

The unusual form of sexual reproduction used by some species of cycads – primeval plants known as “living fossils” – may represent an intermediate step in the evolution of plant pollination, the researchers say.

Thousands of new kinds of marine microbes have been discovered at two deep-sea hydrothermal vents off the Oregon coast by scientists at the MBL (Marine Biological Laboratory) and University of Washington’s Joint Institute for the Study of Atmosphere and Ocean. Their findings, published in the October 5 issue of the journal Science, are the result of the most comprehensive, comparative study to date of deep-sea microbial communities that are responsible for cycling carbon, nitrogen, and sulfur to help keep Earth habitable.

Using a new analytical technique called “454 tag sequencing,” the scientists surveyed one million DNA sequences of bacteria and archaea, two of the three major domains of life.
