Rodent social behavior encoded in junk DNA

...re their young. "If you think of brain circuits as locked rooms, the vasopressin receptor as a lock on the door, and vasopressin as the key that fits it, only those circuits that have the receptors can be 'opened' or influenced by the hormone," added Hammock. "An animal's response to vasopressin thus depend...

MUHC scientists describe genetic resistance to rampant virus

...iller cells and the pathogens they fight have been locked in an evolutionary arms race for millions of years in an attempt to overwhelm each other. Dr. Vidal and her team have spent the past 10 years studying CMV-resistant mouse strains in an attempt to describe the nature of their genetic resistance. "This...

Precise timing enabled pig-to-rat transplants to cure diabetes

... can become virtually any cell type, primordia are locked into becoming a particular cell type or one of a particular set of cell types that make up an organ. In their earlier studies, Hammerman and Rogers had shown that transplantation of pig pancreatic primordia into diabetic rats cures their diabetes p...

Rice, Iowa state biologists search for 'half-fusion'

...yers, but they do not exchange any material that's locked inside. Hemifusion has been observed in non-biological membranes containing no proteins, but has been difficult to detect with SNARE proteins. McNew and his Iowa State colleagues, Yeon-Kyun Shin, Zengliu Su, Fan Zhang and Yibin Xu, developed an ingen...

Natural tumor suppressor in body discovered by UCSD medical researchers

...it has been activated. Since the Akt molecule is locked in the "on" position when it has phosphate on it, the UCSD team reasoned that there must be another molecule that will strip off the phosphate and lock Akt in the "off" position. The scientists conducted a database search of the human genome for a p...

Growth in the sea comes down to a struggle for iron

.... Soil contains lots of iron, but most of it stays locked up in minerals, as accessible to microorganisms as the gold in Fort Knox. Bacteria and fungi have learned to scavenge some of this iron by building a trap. They create molecules called siderophores that are able to lock up iron. And in many cases, on...

Tiny particles could solve billion-dollar problem

...nd on the surface of the particle instead of being locked away inside the metal where they cannot interact with other chemicals. For example, in the bulk palladium, less than 4 percent of the palladium atoms were on surface of the particle. Pure palladium nanoparticles had 24 percent of the metal on the sur...

How do cells travel through our bodies?

...cell movement. Most cells in the body are normally locked to their neighbors, tightly embedded in a tissue. Their connections to their neighbors depend on fibers built from long chains of a protein called actin. For an embryo to form properly, certain types of cells have to immigrate to new locations, where...

UCSD medical researchers discover molecular pathway that turns a juvenile heart into an adult heart

.../SF2 had shortened contractive fiber that appeared locked in a contracted state, leading to sudden death. When ASF/SF2 was normal, heart development progressed normally. "The cascade of molecular events that we have uncovered are directly relevant to understanding heart physiology during development, and ma...

New method to measure ancient land elevation developed by Field Museum scientist

World's top theoretical physicists converge to consider 'future of physics'

...s enabled access from the exterior, they had to be locked at other times. So a physicist working at, say, 6:00 p.m. had to leave via the principal entrance and walk halfway round the building to sit in the courtyard after hours. Most afternoons, sunlight baking the courtyard made it an inhospitable space ...
