200,000 Malaria Deaths Preventable Annually, says U of T Researcher

*Deaths in India vastly underestimated*

Professor Prabhat Jha of medicine and an international team of researchers from India, Canada and the U.K. say their new studty shows the number of premature deaths from malaria in India has been vastly underestimated.

The new study is of a nationally representative sample of all deaths from any cause in India, asking family members to describe the fatal illness. Its results show that malaria accounts for about 200,000 (2 lakh) premature deaths before age 70 in India (including 80,000 children below age 15 and 120,000 adults). Previous estimates of malaria deaths were less than 10 per cent of this new figure. (more…)

Soot From Space Tourism Rockets Could Spur Climate Change

WASHINGTON—Rocket exhaust could become a significant contributor to global climate change in coming decades, according to a new study. The research finds that soot emitted by rockets — not their carbon dioxide emissions — has the greater potential to contribute to global climate change in coming decades. (more…)

Vegetation plays an unexpectedly large role in cleansing the atmosphere, a new study finds. (more…)

Climate Change May Create Tipping Points for Populations, Not Just Species

*Researchers measure survival, reproduction of thousands of arctic and alpine plants over six years*

As Earth’s climate warms, species are expected to shift their geographical ranges away from the equator or to higher elevations.

While scientists have documented such shifts for many plants and animals, the ranges of others seem stable. (more…)

Subprimes Were Not The Culprit In Most Mortgage Meltdowns

ANN ARBOR, Mich. — Subprime mortgages were not the main reason behind the housing crisis that started in 2009 and continues to bedevil the faltering U.S. economy, according to a University of Michigan study. (more…)

The Promise of Ion Beam Cancer Therapy

For certain kinds of cancer, the most effective therapy does not use x-rays or gamma rays but beams of ions, the electrically charged cores of atoms, including hydrogen ions (protons) and heavier ions such as carbon and neon. (more…)

COLLEGE PARK, Md — Scientists at the University of Maryland and Tulane University have developed a computational model of a swimming fish that is the first to address the interaction of both internal and external forces on locomotion. The interdisciplinary research team simulated how the fish’s flexible body bends, depending on both the forces from the fluid moving around it as well as the muscles inside. Understanding these interactions, even in fish, will help design medical prosthetics for humans that work with the body’s natural mechanics, rather than against them. This research is published in the October 18, 2010 online early edition of the Proceedings of the National Academy of Sciences. (more…)

MADE IN IBM LABS: IBM Inventors Create Warning System to Accurately Analyze, Assess and Predict Natural Disasters

ARMONK, N.Y. – 22 Oct 2010: IBM (NYSE: IBM) inventors have developed a patented natural disaster warning system, which uses analytics to improve the effectiveness and timeliness of post-event rescue efforts in cities and other locations where efficient emergency response is essential following a natural disaster. It also offers a means to accurately predict the location and timing of subsequent catastrophic events, which will further aid evacuation efforts. (more…)
