Physicist cracks women's random but always lucky choice of X chromosome

...ctory apparatus. Coming at the problem from the perspective of a physicist Dr Nicodemi has found an explanation for the random selection based on thermodynamics. Research has already shown that at the key moment in this process both X chromosomes are brought close together within the cell. The Warwick researc...

New findings challenge established views on human genome

... DNA sequences that have a functional impact. “Our perspective of transcription and genes may have to evolve,” the researchers state in their Nature paper, noting the network model of the genome “poses some interesting mechanistic questions” that have yet to be answered. Other surprises in the ENCODE data ha...

Researchers publish first marsupial genome sequence

...me sequence also provides researchers with a fresh perspective on the evolutionary origins of the human genome. It sheds light on the genetic differences between placental mammals, such as humans, mice and dogs, and marsupial mammals, such as opossums and kangaroos. "Marsupials are the closest living relativ...

Scripps research study shows humans and plants share common regulatory pathway

...these pathogenic effects. Our study provides a new perspective on the Nod1 pathway in mammalian cells as well as the value of drawing on plant studies of R protein pathways to better understand the pathogen recognition functions of these proteins." The Nod proteins recognize invasive bacteria, specifically d...

Imaging pinpoints brain regions that 'see the future'

...ing memories of specific body movements and visual perspective changes ?data stored as we navigated through similar settings in the past. These findings, McDermott suggests, offer strong support for a relatively recent theory of memory, which posits that remembering the past and envisioning the future draw up...

Imaging techniques permit scientists to follow a day -- or four -- in the life of a cell

...s technique allows researchers to gain a long-term perspective on events in the lives of cells. ...

Analysis of rhesus monkey genome uncovers genetic differences with humans, chimps

...enome is invaluable because it gives researchers a perspective to observe what has been added or deleted in each primate genome during evolution of rhesus, chimp, and the human from their common ancestors ," said Richard Gibbs, Ph.D., director of Baylor College of Medicine's Human Genome Sequencing Center in Hou...

Microbes start immune response by sneaking inside cells

...t triggers the immune response. That creates a new perspective for developing new drugs,?says senior author Gabriel Nunez, M.D., the Paul H. de Kruif professor of pathology at the U-M Medical School and a member of the U-M Comprehensive Cancer Center. For years, scientists have believed that when bacteria inv...

Rotavirus can spread beyond the intestine

Researchers find hepatitis A and hepatitis C attack same protein to block immune defenses

...comes persistent. These results thus provide a new perspective on the chronicity of hepatitis C, which is a highly relevant virus clinically." Hepatitis C has received far more research attention than hepatitis A in recent years, according to Lemon, largely because of hepatitis C’s chronic nature and the lack...

Scientists map key landmarks in human genome

UF scientists discover new genus of frogmouth bird in Solomon Islands

...ts, rodents, small birds ?and yes, even frogs. For perspective on the scale of evolutionary difference between genera, consider that modern humans and Neanderthals are different species within the same genus (Homo), while chimpanzees are our living relatives from a closely related genus (Pan), but that we share ...

Opening windows may be the best way of preventing transmission of airborne infection

... provided the greatest protection. In a related perspective article Peter Wilson, from University College London, concludes that although “natural ventilation is not an easy solution for patients in countries where winters are cold ?the current practice of sealing in the local environment is probably the wron...

Fishy cooperation

...ntelligence is from an evolutionary and ecological perspective focused on the tasks that each species faces in nature. In this regard, these two reef predators show us that if it comes to survival, highly intelligent solutions are within the reach of animals as different from us as fish. (Watch a grouper signal ...

Sea urchin genome suprisingly similar to man and may hold key to cures

...oser to human and vertebrates from an evolutionary perspective than other more widely studied animal models, such as fruit fly or worms. The purple sea urchin, in fact, has 7,000 genes in common with humans, including genes associated with Parkinson’s, Alzheimer’s and Huntington’s diseases and muscular dystrophy...

Carnegie Mellon scientists use 'green' approach to transform plastics manufacturing

...medical implants would be acceptable from a health perspective because they contain so little copper. However, if the target application -- such as a coating for a biomedical stent -- absolutely requires the removal of residual catalyst, companies will now have much less of it to take out, significantly lowering...

What's next for gene therapy? Plastic

... biologists. Polymer scientists can bring a unique perspective that I think will lead to new advances." Long's graduate student, John M. Layman of Richmond, Va., will share information regarding star-shaped, or highly-branched, molecules, which are extremely effective at transfection. Long's group has demonstr...

Study offers window into human behavior, brain disease

... "I think it's fascinating from an evolutionary perspective that we have these new neurons that are involved in social behavior that are selectively vulnerable in the second major degenerative disorder." Notably, VENs are located in regions of the brain that are in a good position to transmit raw emotional...

Blood transfusion-transmitted infections: A global perspective

...thor Dr. Eleftherios Vamvakas of Ottawa, puts into perspective the continuing risk of transfusion-transmitted infections as well as the possible safety interventions that might reduce that risk even further, particularly those due to emerging agents including variant Creutzfeldt-Jakob disease (vCJD) the human co...
