Other highlights in the August 3 JNCI

...ghlights in the August 3 JNCI include a study that finds body size associated with the risk of myeloid leukemia, the identification of a potential colon cancer biomarker, an evaluation of the revised American Joint Committee on Cancer (AJCC) tumornodemetastasis staging system and its use after neoadjuvant ...

Weapon performance determines mating success in the collared lizard

...fitness than body size and weapon size. The study finds that bite-force performance was a strong predictor of reproductive success. However, no size measure was correlated with any estimate of mating success or with potential reproductive output. These results counter the conventional wisdom that bigger i...

Study reveals new information on the direct and indirect mate choice in lekking animals

...n the August 2005 issue of The American Naturalist finds that female great snipes are not attracted to centrally located males or previously popular sites on mating arenas (leks). The findings, which question the widespread beliefs about the lek mating system, were gathered by a team of Norwegian and Swedi...

Defective sweet taste receptor gene shapes cat cuisine

... Research program at the Waltham Centre. "Waltham finds it critical to understand these unique characteristics of the cat in order to make foods that they not only enjoy but that also meet their unique nutritional needs." Parallel studies showed that the defect is specific to the gene coding for the T1R2 ...

Engineers create optoelectronic tweezers to round up cells, microparticles

...Berkeley Sensor and Actuator Center. "A technician finds the cell of interest under a microscope and literally cuts out the piece of glass where the cell is located, taking care not to harm the sample." "Our design has a strong practical advantage in that, unlike optical tweezers, a simple light source, su...

Japanese team finds inhibition of excitatory and inhibitory synaptic transmission In an in vitro study, a multi-center Japanese team led by Atsushi Soya focused on the supraoptic nucleus (SON) where vasopressin and oxytocin are synthesized. They found that a synthesize...

Environment more than genes determines child's social aggressiveness

...July/August issue of the journal Child Development finds that this form of aggression, usually an outgrowth of physical aggression, is related more to a child's environment than to his or her genetic background, suggesting that intervention could have a significant effect. Study researchers from the Univer...

UF study finds cell mutations that lead to apoptosis may contribute to aging in mammals

...lished in this Friday's issue of Science magazine, finds that accumulation of mitochondrial mutations that promote apoptosis, or programmed cell death, may be a central mechanism driving aging and may be unrelated to the release of free radicals, previously thought to cause aging. This may be because of an...

Study: Predatory dinosaurs had bird-like pulmonary system

...keleton in areas such as the neck, chest and hips, finds similarities between the vertebral column of dinosaurs and birds that point to a common soft tissue system as the culprit. Though probably not identical to living birds, "it's nothing like the crocodile system as we know it," O'Connor said. "The pulm...

Good connections are everything

...if one starts from an ordered network pattern, one finds that this ordered pattern is very robust with respect to perturbations of randomly chosen nodes but rather sensitive with respect to selective perturbations of the highly connected nodes. In fact, the relative fraction of highly connected nodes that ...

Revueltosaurus skeleton unearthed at Petrified Forest upsets dinosaur tale

... University of California. Parker's initial fossil finds were crocodilian-like armor, but he didn't realize they were from Revueltosaurus until the next day, when he brought a colleague to the site and she picked up a jaw with teeth. During May and June of 2004, Parker, Irmis and their coauthors excavated ...

CBEN: Buckyball aggregates are soluble, antibacterial

...er for Biological and Environmental Nanotechnology finds that the molecules spontaneously clump together upon contact with water, forming nanoparticles that are both soluble and toxic to bacteria. The research challenges conventional wisdom: since buckyballs are notoriously insoluble by themselves, most sc...

Single cell recognition research at UCLA/Caltech finds a Halle Berry neuron

...ch team led by neuroscientists at UCLA and Caltech finds that individual neurons are able to recognize people, landmarks and objects even letter strings of names. The findings suggest a consistent, sparse and explicit code that may play a role in transforming complex visual representations into long-term...

Study: Harmless virus kills some cancers

...with a helper virus in order to replicate. When it finds a helper virus, such as HPV, AAV2 disrupts the life cycle of the host and induces apoptosis, a type of cell death. "Even without co-mingling with another virus, AAV2 seems to be able to infect and express itself in other types of cancer cells also d...

Researchers find evidence of photosynthesis deep within the ocean

...SU's chemistry and biochemistry department. "Life finds a way," Blankenship said of the plucky bacteria that were found in a vent field called 9 North off the coast of Mexico. The bacteria apparently live in the razor thin interface between the extremely hot water (350 C) coming from a flange vent and the...

Research zeros in on bipolar disorder genes, link with thyroid condition

...o finding the elusive gene or genes. Another study finds an association between an abnormal thyroid condition and bipolar disorder, pointing to the possibility that a simple blood test could help identify those at risk. To further investigate more specific genetic linkages, Marion Leboyer, M.D., Ph.D., of...

When in danger humans are similar to a deer in the headlights

The mere picture of an injured or mutilated human induces this reaction. When viewing these unpleasant images, the study's participants froze as their heart rate decel...

Phorboxazole A is a potent toxin that in the laboratory, can inhibit the growth of a wide range of tumor cell types even at very low conc...

Lactose intolerance linked to ancestral environment

...ey can't digest it. A new Cornell University study finds that it is primarily people whose ancestors came from places where dairy herds could be raised safely and economically, such as in Europe, who have developed the ability to digest milk. On the other hand, most adults whose ancestors lived in very hot...
