Researchers at the UCSD School of Medicine, led by Ajit Varki, M.D., have shown a new mechanism for how human consumption of red meat and milk products could contribute to the increased risk of cancerous tumors. Their findings, which suggest that inflammation resulting from a molecule introduced through consumption of these foods could promote tumor growth, are published online this week in advance of print publication PNAS.

Confusion of the senses can lead to serious consequences for airplane pilots. This perception problem, known as spatial disorientation, is also a major concern for astronaut pilots, especially those who will perform lunar landings. Scientists and engineers with the National Space Biomedical Research Institute are developing a tool that will provide real-time assistance to pilots during spatial disorientation events in Earth’s atmosphere and in space.

A study released by researchers at the Columbia Center for Children’s Environmental Health at Columbia University’s Mailman School of Public Health shows that developing antibodies to cockroach and mouse proteins is associated with a greater risk for wheeze, hay fever, and eczema in preschool urban children as young as three years of age. The study is the first to focus on the links between antibody responses to cockroach and mouse proteins and respiratory and allergic symptoms in such a young age group.

A new cross-Canada study has found that breast and prostate cancer treatment can foster bone loss. In the online edition of the Journal of Clinical Oncology, the scientists explain how loss of bone mass might affect 46,000 people diagnosed with breast and prostate cancer each year and place them at increased risk for osteoporosis and fractures.

Electroshock weapons, such as stun guns and other similar devices that temporarily incapacitate a person by delivering a high-voltage, low-current electric shock, have helped law enforcement officers safely subdue dangerous or violent persons for years. Researchers at NIST are working toward a standard method for accurately assessing the electrical output of these devices, the results of which can be used in establishing baselines for future medical and safety studies.

Extremely small nanoscale particles are released by common kitchen appliances in abundant amounts, greatly outnumbering the previously detected, larger-size nanoparticles emitted by these appliances, according to new findings by NIST researchers.

Scientists at NIST have developed a radical new method of focusing a stream of ions into a point as small as one nanometer, a versatile ion source that is expected to have broad application in nanotechnology both for carving smaller features on semiconductors than now are possible and for nondestructive imaging of nanoscale structures with finer resolution than currently possible with electron microscopes.
