Detecting Cancer with Lasers Has Limited Use, Say Mu Researchers

COLUMBIA, Mo. — One person dies every hour from melanoma skin cancer in the United States, according to the American Cancer Society. A technique known as photoacoustics can find some forms of melanoma even if only a few cancerous cells exist, but a recent study by University of Missouri researchers found that the technique was limited in its ability to identify other types of cancer. Attaching markers, called enhancers, to cancer cells could improve the ability of photoacoustics to find other types of cancer and could save lives thanks to faster diagnoses, but the technique is in its early stages.

“Eventually, a photoacoustic scan could become a routine part of a medical exam,” said Luis Polo-Parada, assistant professor of pharmacology and physiology and resident investigator at the MU Dalton Cardiovascular Research Center. “The technique doesn’t use X-rays like current methods of looking for cancer. It could also allow for much earlier detection of cancer. Now, a cancerous growth is undetectable until it reaches approximately one cubic centimeter in size. Photoacoustics could potentially find cancerous growths of only a few cells. Unfortunately, our research shows that, besides some cases of melanoma, the diagnostic use of photoacoustics still has major limitations. To overcome this problem, the use of photoacoustic enhancers like gold, carbon nanotubes or dyed nanoparticles is needed.” (more…)

SAN FRANCISCO – June 23, 2011 – A collection of students who want to change the world with technology pitched their ideas to Silicon Valley industry experts, academics, and media on Wednesday.

Several teams of students who will participate in the July Imagine Cup 2011 Worldwide Finals in New York City got to first showcase their projects to people who could help them refine their concepts, find markets for their ideas, and eventually find investors to provide the money they will need to turn their ideas turn into viable businesses.

Researchers from the Georgia Tech Research Institute (GTRI) are helping to automate human resource information systems for health care professionals in two African nations, Kenya and Zimbabwe.

In collaboration with Emory University’s Lillian Carter Center for International Nursing and the Task Force for Global Health, GTRI is evaluating and advising on computer systems developed to provide information for better human resource management, policy development and health planning. (more…)

Crocodiles 168 Times More Dangerous Than Sharks

The fears connected with shark attacks are stronger in the world today than those related to much more dangerous predators – crocodiles. However, crocodiles pose a greater threat to humans than sharks do.

A crocodile snatched Hendrik Coetzee, a South African guide, 35, from his kayak while he led an American expedition into the heart of Congo last week. Two American tourists could only watch the scene in horror as the guide was killed and eaten by the predator. They paddled to safety unharmed. Coetzee’s body has not been recovered.

Stories about croc attacks are just as terrible as they are hopeless. Experts say that it is possible to stay to fight off a shark, but it is much more difficult or even impossible to rescue themselves from an attacking croc. (more…)

EAST LANSING, Mich. — While Asian carp, gypsy moths and zebra mussels hog invasive-species headlines, many invisible invaders are altering ecosystems and flourishing outside of the limelight.

A study by Elena Litchman, Michigan State University associate professor of ecology, sheds light on why invasive microbial invaders shouldn’t be overlooked or underestimated.

“Invasive microbes have many of the same traits as their larger, ‘macro’ counterparts and have the potential to significantly impact terrestrial and aquatic ecosystems,” said Litchman, whose research appears in the December issue of Ecology Letters. “Global change can exacerbate microbial invasions, so they will likely increase in the future.” (more…)

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…)

ANN ARBOR, Mich.—There are hundreds of millions of new cases of malaria annually, but much of what scientists believe about preventing the spread of malaria in urban settings is mistaken, a new University of Michigan study suggests.
