Bobbing birds do it for a reason

...he motion of their bodies, and thereby enables the accurate detection of objects such as food items. The motion associated with the head-bobbing behavior consists of alternate phases of holding the head still and rapidly thrusting it forward during each step. This behavior, found in birds but in no other ver...

Cousin of Asian super termite invades Florida

...searchers and pest control officials try to get an accurate estimate of the new termite's range in South Florida, the Formosan termite continues to spread its destruction across Florida and much of the southeastern United States. First identified by UF/IFAS researchers in Miami-Dade and Broward counties in t...

Research into how prions act in the brain could hold the key to defeating diseases

...eriorate rapidly. There is currently no simple and accurate way to diagnose types of prion disease such as vCJD, no effective way of managing or treating patients and no cure is yet in sight. Estimates of the numbers of people at risk from primary exposure to meat infected products and possible risk from sec...

Whole-body MRI Takes Less Than 20 Min To Scan A Patient's Entire Body For Cancer Spread To Bone

...ermany, also found that whole-body MRI is fast and accurate for discovering bone metastases. However, they discovered that whole-body FDG-PET is superior to whole-body MRI in for staging lymph nodes, soft-tissue tumors and metastasis in the internal organs. For that study, the researchers scanned 120 patient...

Insects, viruses could hold key for better human teamwork in disasters

Climatologists discover deep-sea secret

...search published today in Science will enable more accurate forecasts to be made on how the oceans will react to climate change. The scientists have observed that at several periods in history when the temperature has increased in the northern hemisphere, the southern hemisphere has entered a cooling period,...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

...s through activation of the p53 pathway. Having an accurate view of how p53 is regulated will allow the development of specific drugs that unleash the killing power of p53 by interfering with its negative regulators. Our cells are vulnerable to DNA breaks caused by UV light, ionizing radiation, toxic chemica...

Team Invents Device For Weighing Individual Molecules

...hydrogen atoms can be weighed. Such an intricately accurate method of determining atomic-scale masses would be quite useful in areas such as quantum optics, in which individual atoms are manipulated. The next step for Roukes' team at Caltech is to engineer the interfaces so that individual biological molecul...

The making and breaking of microtubules

...nt to find their goals -- a process crucial to the accurate deployment of spindles during cell division, for example -- and how drugs can be designed and targeted to put a monkey wrench into the growth of cancer cells. "Nucleotide-dependent bending flexibility of tubulin regulates microtubule assembly," by H...

Program finds lost genes in nematode genome

...WINSCAN analysis of C. Elegans is able to use more accurate models of intron length than previous analyses. Th... process is 15 times slower than the typical, less accurate methods. Being able to define intron length has implications for the human genome, which is much lar...

Study shows humans have ability to track odors, much like bloodhounds

...s task, I could look at the brain and tell you how accurate he or she would be on every trial and on the task overall," Sobel said. "So the fact that we have this predictive value in the data really suggests that we have actually successfully captured the mechanism." What's more, another area of the brain ou...

Scalpel-free surgery could reduce risk of HIV and hepatitis exposure for health care workers

...nd C among patients presenting for surgery, a more accurate incidence of disease is measured within a community, bypassing the selection bias of traditional statistics of known infected patients presenting to primary care clinics. Furthermore, the authors report that blood-borne pathogens are associated with ...

In the SIGGRAPH installation, the representations are rendered in a 40-foot wide and 12-foot tall space by five video projectors, with the figures for human genes/proteins shown along a vertical ...

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'

...h they cross-registered with the PET scans to give accurate information on exactly which brain regions were active. Because carfentanil competes with the brain's natural endogenous opioid painkillers for space on nerve cell receptors, the PET scans can be used to see how active the opioid system and mu-opio...

Woods Hole Research Center plans controlled burn in Amazon rainforest

According to Nepstad, "One of the discoveries from our first year of burning is that forest understor...

Carnegie Mellon University research reveals how cells process large genes

Important messages require accurate transmission. Big genes are especially challenging because they combine many coding segments (exons) that lie between long stretches of non-coding elements (introns). During processing, introns are snipped out and exons pasted together to form a temp...
