NAU researchers chirping over discovery of new cricket genus

...nder way at the USGS. He is developing methods for detecting caves using thermal remote sensing technologies. Once procedures are developed, these techniques ultimately will be used to find caves on Mars. Once his team identifies Martian caves, robotic cave explorers will be developed to search for life under ...

Do angry men get noticed?

...ork suggests that although males are biased toward detecting threatening faces, and females are more attuned to...in short, angry men get noticed. The advantage for detecting angry male faces is consistent with the notion that human perceptual processes have been shaped by e...

Thermal imaging shatters arousal gender gap myth

...on their temperature. Because of its usefulness in detecting warm objects in the dark, most people know it as the technology used in night vision goggles for military operations. Previously, sex researchers have measured arousal with instruments that require genital contact and manipulation. Binik fo...

Sandia research to focus on early detection of harmful algal blooms

...irtually every coastal region. Current methods for detecting the poisonous toxins characteristic of the blooms ...d under this effort will be equally well suited to detecting algal toxins in freshwater sources and complements other ongoing research at Sandia. Sandia's Water ...

Elasticity imaging identifies cancers and reduces breast biopsies

...icipates that elasticity imaging will also help in detecting cancers, but did not evaluate that capability for this study. Dr. Barr and colleagues are planning to expand their research in an international, multicenter trial beginning in January 2007. ...

A new understanding of how cells defend themselves against bacterial pore-forming toxins

...e a sort of roving security force inside the cell, detecting a variety of danger signals such as bacterial RNA or bits of bacterial flagellin. The inflammasomes join together and activate a protein, caspase-1, that in turn triggers an inflammatory response. Van der Goot and her colleagues found that in addi...

Cancer stem cells linked to radiation resistance

...les for specific proteins that are responsible for detecting DNA damage. Using cell samples taken from both study models, the team examined the DNA damage checkpoint response both before and after use of ionizing radiation treatments by testing for activation of the key proteins that detect DNA damage. The res...

Professors to develop hand-held pathogen testing device

...developing a portable, hand-held device capable of detecting up to 50 microbial threat agents in air, water and food. "This device will give us the ability to measure pathogens in a manner and at a price that really matters for human health," Hashsham said. "If we can screen for all pathogens together, we c...

Bitter taste identifies poisons in foods

...dings show that our taste receptors are capable of detecting toxins in the natural setting of the fruit and vegetable plant matrix," said senior author Paul Breslin, a Monell sensory scientist. Glucosinolates act as anti-thyroid compounds. The thyroid converts iodine into thyroid hormones, which are essenti...

Two central mysteries in genome inheritance solved at UCSD

...rmation," said Desai. Cells avoid such a fate by detecting errors in attachment to the spindle, breaking down these defective attachments and starting over. But until now, scientists did not understand how cells detected such an error. Sharsti Sandall, a graduate student in the Biomedical Sciences Progra...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

...ntainment, if done quickly, within a day or two of detecting the first smallpox case, would contain a large attack if up to 500 people were infected," said Longini, a member of the Public Health Sciences Division at the Hutchinson Center and a professor of biostatistics at the University of Washington School o...

UCLA researchers unravel a mystery about DNA

...ese studies," Ebright said. "These methods involve detecting and manipulating single molecules, one at a time -- a breakthrough in its own right." "The study of molecular machines, the dynamics of their moving parts and their translocation on molecular tracks is of great interest to nanotechnologists at the...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

... journal Nano Letters ?could save lives by rapidly detecting a naturally occurring disease outbreak or bioterrorism attack. "It saves days to weeks," said lead author Ralph Tripp, Georgia Research Alliance Eminent Scholar in Vaccine Development at the UGA College of Veterinary Medicine. "You could actually ...

Climate experts search for answers in the oceans

...the surrounding ocean waters, providing a means of detecting these tiny organisms from space with dedicated ocean colour sensors. "Because phytoplankton are a major influence on the amount of carbon in the atmosphere and are sensitive to environmental changes, it is important to monitor and model them into...

Faster, more accurate tuberculosis test developed

...d light microscope for 40 days. The sensitivity of detecting TB was 97.8 percent for MODS culture, 89 percent for automated mycobacterial culture and 84 percent for Lowenstein-Jensen culture, when compared to each other. The median time for detection of TB was 7 days for MODS culture, 13 days for automated myc...

Small, smaller, smallest -- The plight of the vaquita

...06 or 2007 would have a probability of only 11% of detecting a 3%/year decline and a 16% probability of detecting a 10%/year decline. Achieving an acceptable probability (e.g. 95%) of detecting a 3% decline would r...

Scientists design simple dipstick test for cocaine, other drugs

...mpaign have developed a simple "dipstick" test for detecting cocaine and other drugs in saliva, urine or blood serum. The test is based upon DNA-gold nanoparticle technology, and can be packaged in user-friendly kits similar to those used for home pregnancy tests. "Building upon our earlier work with lead (Pb...

Train your brain to hear your friends at a party

...ility and by the end of the period were as good at detecting the location of the sounds as they were before being fitted with an earplug. Something in their brain was changing or adapting to the new situation and they were learning to compensate for the hearing loss. Irving said: "When we switch on a bri...

Molecules in blood foretell development of preeclampsia

...of only one or the other." Dr. Levine added that detecting high levels of both soluble endoglin and sFlt1 early in pregnancy might be especially helpful in predicting the later development of preeclampsia. Detecting high levels of these molecules might also help in distinguishing preeclampsia from chronic h...

Molecular 'marker' on stem cells aids research, perhaps therapies

...velopmental Biology and of molecular biology, said detecting SSEA-4 will aid in singling out the mesenchymal stem cells, or MSCs, for more detailed scientific study as well as for possible medical applications. The cells have shown promise in early clinical studies elsewhere, where scientists tested their use ...
