...del of evolution," he said. The studies also raise intriguing questions about the influence that bacteriophages have on their bacterial hosts. "We had known that bacteriophages can be intimately involved in the pathogenesis of their bacterial hosts, such as the infamous pathogenic E. coli," said Hatfull. "But i...

New potential therapy for sickle cell disease

...n -- A study from Children's Hospital Boston gives intriguing preliminary evidence that inhaling the gas nitric oxide may relieve the vaso-occlusive pain crises suffered by patients with sickle-cell disease. Appearing in the March 5 edition of JAMA, this is the first published study of inhaled nitric oxide for ...

New hints into development of osteoporosis

...raction between M-CSF and alphaV beta3 integrin is intriguing and may help explain some of the less-understood aspects of animal models of osteoporosis," Teitelbaum says. Because of this interaction, Teitelbaum and colleagues also explored whether alphaV beta3 integrin and M-CSF are involved in the same signal...

Squirrels' evolutionary 'family tree' reveals major influence of climate, geology

... South America was still presumably isolated. "The intriguing question is: where were its ancestors during that very long time since its divergence from other squirrels?" Roth asked. Other surprises include new questions about the evolutionary branching off of flying squirrels. "Our results argue against the lo...

Methane and mini-horses: Fossils reveal effects of global warming

...As the warm spell continued, the animals showed an intriguing response: they became smaller. For example, "horses from this period that had been the size of a small dog were reduced to the size of a Siamese cat," Gingerich said. When the climate returned to normal, the animals became normal size again. To under...

High sugar blood levels linked to poor memory

...ficits that occur as people age, and it raises the intriguing possibility that improving glucose tolerance could reverse some age-associated problems in cognition. The brain uses glucose almost exclusively as a fuel source. It was once generally believed that brain occupied a privileged position it could get...

Coat-color gene mutation mimics neurodegeneration of prion diseases

...oat-color gene, called Attractin , turned up some intriguing results. "Both gene mutations have been recognized as coat-color mutations for decades," said Barsh. "In the last few years, our group and others recognized that Attractin mutations affected not only hair color but also caused neurodegeneration wit...

American Physical Society March Meeting 2003

... of 2002. At session G10, researchers will present intriguing findings on the folding properties of RNA. Ranjan Mukhopadhyay ( ranjan@research.nj.nec.com ) and his colleagues at NEC Laboratories in New Jersey have found that a typical RNA sequence with its 4-letter code folds more predictably and stably than wo...

Checkpoint protein blocks chromosome breaks at fragile sites

...e have more fragile site breaks. One of the most intriguing things about fragile sites, says Glover, is that they are found in humans, primates, mice and possibly even yeast. "These are regions of DNA that are prone to breakage and difficult to replicate, so why have they been conserved by evolution for milli...

New theory explains economic growth in terms of evolutionary biology

...," said Galor. The theory generates an alternative intriguing prediction, he said. "It suggests that during the epoch of stagnation, men who were from a physiological viewpoint moderately fertile (men with a moderate sperm count), and who were therefore induced by nature to invest more in the quality of their o...

Even green pond scum can suffer from jet lag

...otes controls only 5 to 10 percent. Johnson has an intriguing idea about how this bacterial clock might work. It takes advantage of the fact that blue-green algae's chromosome takes the form of a circle, rather than long linear molecules as is the case in higher organisms. Double-stranded DNA can exist in two b...

Scientists discover ancient protein and DNA sequences in the same fossil

Mole-rat Methuselahs push evolutionary theory of aging

...ed have helped zookeepers worldwide to display the intriguing creatures for the education of the general public. In nature, naked mole-rats are known to live at least 10 years. "We think they live longer in the laboratory than they do in the wild because they're safer here, but they're pretty safe in nature, to...

Bloodworm's way with copper likely provides paradigm for new materials

...er mineral as well as with bound copper ions is an intriguing concept per se but may also serve as a design prototype for new materials that need to be hard, lightweight, and durable." In addition, they found the non-mineral form of copper on the surface of the jaw canal through which venom is injected. That ...

A red flag for lethal prostate cancer

...g clinical outcome than any other factor." Another intriguing finding reported in the Nature paper was the use of a new technique called RNA interference to inhibit production of EZH2 protein in cancer cells. RNA is the messenger molecule that copies DNA's genetic instructions and delivers them to the cell's pr...

Researchers discover genes that control regulatory functions in malaria mosquitoes

...ive insulin-like peptides. The scientists followed intriguing hints that Plasmodium appears to use insulin from either the female mosquito or the vertebrate blood meal for its own development, metabolism and reproduction. The importance of that connection could be crucial to understanding how the parasites are ...

Advances in 'micro' RNA exploring process of life

...On this frontier of biology, experts say, the most intriguing new component is micro-RNA, a minuscule type of regulatory molecule that had seemed insignificant even in the extraordinarily tiny, microscopic world of cell biology. The first micro-RNA, in fact, was only discovered in 1993 and at the time was thoug...

Dinosaur ancestor's vision possibly nocturnal

...ort dim-light vision. "This is consistent with the intriguing though controversial possibility that nocturnal, not diurnal, life histories may have been the ancestral state in amniotes, which are birds, reptiles and mammals whose embryos are protected with a fluid-filled sac," says Belinda S.W. Chang, Ph.D., fi...
