T-rays: New imaging technology spotlighted by American Chemical Society

...hoto-excited reactions, information that cannot be acquired with any other technique. "We have also devised a system that captures the THz pulse emitted during rapid intramolecular charge transfer using two different dye molecules," he said. "In the future we will use this method to probe photosynthetic and b...

Sooner is better with cochlear implants, Stanford scientist shows

...th cochlear implants were able to meld their newly acquired hearing capability with their ability to read lips. In other words, did their brains process speech the same way as people who are born with the ability to hear? In the Dec. 5 online edition of the Proceedings of the National Academy of Sciences, th...

Performing monkeys in Asia carry viruses that could jump species to humans

...e animal markets where many performing monkeys are acquired by their trainers. The markets typically bring together many different species of wild monkeys, as well as many other types of animals, in very close, unnatural quarters and unsanitary conditions. "The market is a condensed area for mixing species ...

Fitting in: Newly evolved genes adopt a variety of strategies to remain in the gene pool

...ies: (1) back-up, where a duplicate gene copy has acquired the ability to compensate in the absence of the other copy, (2) subfunctionalization, where a duplicate copy has evolved a completely new, non-overlapping function, (3) regulation, where the differential regulation of duplicates fine-tunes pathway us...

Wild Gorillas Handy with a Stick

...ng detached objects as tools. However the gorillas acquired their skills, these observations suggest that the intelligence required for tool use evolved before the gorilla lineage split off from humans and the other great apes—providing further evidence that intelligence is not unique to humans. ...

Novel protein complex enables survival in hostile environment

... developed in another organism and the methanogens acquired the sulfite reduction gene via horizontal transfer from that entity," Mukhopadhyay said.

NIAID researchers show how promising TB drug works

...ogether, while the remaining two mutants evidently acquired resistance to PA-824 through a mutation that made the protein unable to bind to the drug, Dr. Barry says. With the discovery of the specific protein that interacts with PA-824, Dr. Barry and colleagues, including researchers at the Novartis Institut...

Wright bros. upstaged! Dinos invented biplanes

...began to stay aloft longer by gliding, and finally acquired powered flight. As those abilities developed, feathers became larger and more specialized, providing greater lift and thrust. The Chinese feathered dinosaurs show these transitional stages of flight. In contrast, the ground-up theory has a thero...

Sudden change in social status triggers genetic response in male fish, study finds

... top fish now and will vigorously defend his newly acquired breeding grounds. "We found that when the dominating male is removed, the subordinate male perceives an opportunity to advance in social status and responds both behaviorally and by turning on genes that ultimately make him capable of reproducing,"...

Study provides insight into cellular defenses against genetic mutation

...late for an essential protein because the mRNA has acquired a nonsense codon. "Our study is important because we have determined for the first time that the mRNA-binding protein CBP80 tells the NMD system which mRNAs to review for nonsense codons," according to Lynne E. Maquat, Ph.D., professor of Biochemist...

Scientists crack 40-year-old DNA puzzle and point to 'hot soup' at the origin of life

... this suggests that heat prevented them from being acquired by the code at some point in the past. One possible reason for this is that the Last Universal Common Ancestor (LUCA), which evolved into all life on earth, lived in a hot sulphurous pool or thermal vent. As it moved into cooler conditions, it was a...

Emerging staph strains found to be increasingly deadly and deceptive

...emic of MRSA in the community." S. aureus strains acquired in health-care settings can be challenging to resolve because of antibiotic resistance, which limits the choices for treatment. But the situation can become more serious with the newer community-acquired strains, says Dr. DeLeo. "We do not know why c...

Prescription pain patch abuse blamed for increase in deaths

... prescription or it was purchased on the street or acquired from a friend, so it has been diverted to them," Goldberger said. Goldberger's team, which includes Mark Gold, M.D., a distinguished professor with UF's McKnight Brain Institute and chief of the division of addiction medicine, has been focused on th...

Drug resistant avian influenza viruses more common in Southeast Asia than North America

...sure refers to the extent to which an organism has acquired either a beneficial genetic trait that gives it a survival advantage in a particular environment and therefore makes the organism more likely to survive and multiply; or a trait that makes it vulnerable to something in the environment, and therefore ...

Mosquito study shows new, faster way West Nile can spread

...etween 2 and 6 percent of the recipient mosquitoes acquired the virus. In one trial, a single bite from a donor mosquito was sufficient to infect two out of 87 recipient mosquitoes. The discovery calls into question the current conception of mosquito transmission of West Nile virus and possibly other viruses...
