Fungal factories may save hemlock forests

...all this white growth?" Costa says in his UVM lab, tracing his finger above the soft flat needles. "That's mycelium and likely as not there are spores at the end of each of those." To the untrained eye, the fungus he and Grassano are growing looks much like the pest they hope it will fight. Hiding on the und...

Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers

A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today. The study was undertaken in the UK by scientists at Imperial College London and the Z...

Studies yield insight into the numerical brain

...plications. "Developmental studies should focus on tracing the emergence of numerical representation in the brain, investigating in particular at which stage such a representational divergence appears. Such findings could contribute significantly both to the field of numerical cognition research and rehabili...

Bones in motion: Brown scientists to create new 3-D X-ray system

... a torn knee ligament or an evolutionary biologist tracing the disappearance of digits in pigs would face a difficult task. To see the exact position and movement of bones and the ligaments, tendons and cartilage that surround them, would require cutting into flesh ?not a desirable option. The new system,...

...ing in the current that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week. The team, led by Alberto Naveira Garabato of the National Oceanography Centre, Southampton (formerly based at the University of East Anglia), has discovered...
