EARTH: 5 outstanding questions in Earth science

What are today's biggest unanswered questions in earth science? In the July issue of EARTH Magazine, experts from a variety of disciplines weigh in on what they consider to be the biggest unsolved mysteries across the geosciences and how they think we may solve them.

Efforts to develop new drugs that hopefully will never be used

Concerns about terrorist attacks, the prospect of a rogue nation using nuclear weapons and the Fukushima power plant accident in Japan are fostering efforts to develop a new family of drugs that everyone hopes will never be used, according to an article in the current edition of Chemical & Engineering News, the weekly news magazine of the American Chemical Society, the world's largest scientific...

Finding brings scientists 1 step closer to Parkinson's drug

The Van Andel Institute announces that researchers at Lund University in Sweden have published a study detailing how Parkinson's disease spreads through the brain. Experiments in rat models uncover a process previously used to explain mad cow disease, in which misfolded proteins travel from sick to healthy cells. This model has never before been identified so clearly in a living organism, and the...

Half of inhaled diesel soot gets stuck in the lungs

The exhaust from diesel-fueled vehicles, wood fires and coal-driven power stations contains small particles of soot that flow out into the atmosphere. The soot is a scourge for the climate but also for human health. Now for the first time, researchers have studied in detail how diesel soot gets stuck in the lungs. The results show that more than half of all inhaled soot particles remain in the...

Immune response to heart attack worsens atherosclerosis, increases future risk

A heart attack doesn't just damage heart muscle tissue by cutting off its blood supply, it also sets off an inflammatory cascade that worsens underlying atherosclerosis, actively increasing the risk for a future heart attack. These findings from a study receiving advance online publication in Nature suggest an important new therapeutic strategy for preventing heart attacks and strokes, both of...

Injecting life-saving oxygen into a vein

Patients unable to breathe because of acute lung failure or an obstructed airway need another way to get oxygen to their blood -- and fast -- to avoid cardiac arrest and brain injury. A team led by researchers at Boston Children's Hospital has designed tiny, gas-filled microparticles that can be injected directly into the bloodstream to quickly oxygenate the blood.

Innovative technique enables scientists to learn more about elusive exoplanet

One of the first planets discovered outside of the Solar System, Tau Bootis b, has eluded numerous attempts to measure the light coming from its atmosphere and so has remained something of a mystery. Now, for the first time, an international team has used an innovative technique to unravel direct light from the exoplanet itself to reveal its mass and orbit. Their results will be reported in Nature...

Math goes to the movies

Dr. Robert Bridson of the University of British Columbia will talk about the math and physics behind a broad range of 3D special effects used in movies and computer animations at the Hyatt Regency Minneapolis from 6:15-7:15 p.m. on Wednesday, July 11.

Mining cleanup benefits from Texas A&M expertise

When Atlantic Richfield Co. was tasked with cleaning up a major superfund site it had purchased in Montana, Dr. Frank Hons, a Texas A&M University professor, got a call to assist the company's consultants, Pioneer Technical Services.Hons, a soil and crop science professor, spent two years leading a Texas A&M team studying revegetation solutions on land impacted by 100 years of copper mining,...

Most new pesticides have roots in natural substances

Scientists who search for new pesticides for use in humanity's battle of the bugs and other threats to the food supply have been learning lessons from Mother Nature, according to a new analysis. It concludes that more than two out of every three new pesticide active ingredients approved in recent years had roots in natural substances produced in plants or animals. The article appears in ACS'...

NASA observes the Waldo Canyon Fire, Colorado

NASA satellites continue to provide coverage of the smoke and heat signatures generated from wildfires raging in the western United States. The Waldo Canyon Fire is threatening populated areas, and is located near Colorado Springs, Colo.

New animal model for rheumatoid arthritis

Researchers have created the first animal model that spontaneously develops rheumatoid arthritis (RA) and is predisposed towards hardening of the arteries. This model is considered of critical importance because patients with RA are at increased risk for heart attack and other premature cardiovascular events, but scientists don't know why.
