UC Riverside psychologist explores human perception, finds 'wow factor'

...l motivated by theoretical questions rather than a quest for a particular application, Rosenblum said, but real-world considerations are important. "We discuss practical applications in papers so engineers can use them in the work they do, whether it's designing computer software or rehabilitation program...

A step forward in the fight against bacterial infections

... results of this research are very relevant to the quest for new therapeutics for bacterial infections. The mutant mice display a combination of important characteristics: they are resistant to LPS, but they still recognize and destroy pathogens. The limited quantity of type 1 interferons enables the mice ...

Study fishes out new role for prostaglandins

... colon cancer, DuBois explained. "We've been on a quest for the last 10 years to understand why such a simple drug leads to such a significant reduction in cancer risk," he said. "There are several parts to that puzzle. This (finding) may be one piece." Zebrafish models may seem like a step back from th...

ANU scientists crack DNA replication mystery

New genes implicated in rheumatoid arthritis

...rence among siblings seems to be random. In the quest to identify disease-specific gene expression profiles in patients with RA, researchers at the University of Michigan Medical Center turned to an ideal population: genetically identical, disease-discordant twins. The July issue of Arthritis & Rhe...

NHGRI announces latest sequencing targets

...us leucogenys), setting the stage for completing a quest to sequence the genome of at least one non-human primate genome from each of the major positions along the evolutionary primate tree and making available an essential resource for researchers unraveling the genetic factors involved in human health an...

Research highlights how bacteria produce energy

...h a high (86%) yield. This is the first step in a quest to develop bacteria that can breakdown and ferment cellulose biomass directly to ethanol. "Currently ethanol is produced primarily from sugarcane or cornstarch, but much more biomass in the whole plant, including stems and leaves, can be converted t...

Protein-coated dental implants could improve bone regeneration

...ö says. "For the past 20 years, there has been a quest to regenerate tissues around teeth that are lost due to periodontal disease," he says. "I've looked at multiple approaches to achieve regeneration, including bone grafts, root conditioning and membrane devices for directed tissue growth, all resultin...

Study shows frogs can play key role in stem cell research

...it will become an important research tool in their quest to understand and, ultimately, treat disease using stem cells. The results of their study are published in the current edition of the journal Development. The key protein in humans, called Oct4, which governs the process of unlimited division of ste...

Plague proteome reveals proteins linked to infection

... and can guide drug and vaccine designers in their quest to disrupt the microbe’s ability to infect. Y. pestis is the bacterium that caused the infamous Black Death plagues. Fleas are vectors for the disease and can spread it to rodent and human hosts. This study mimicked environmental conditions of Y....

Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

...w radiation causes cognitive impairment, part of a quest for biological countermeasures to reduce radiation-related cognitive impairment. The NASA-funded $14-million research project could not only help eliminate the risks to astronauts, it could unravel the biomechanics of brain damage, potentially bene...

Microbe fixes nitrogen at a blistering 92 C

...mperatures"'" says Baross, who’s been on a 20-year quest to find just such a microbe. Archaea are single-celled organisms that live under extreme environmental conditions, such as the high temperatures and crushing pressures below the seafloor. If heat-loving archaea were the first life on the planet, they...

Most important actors in the growth process of neurons identified

...clerosis (ALS), or Multiple Sclerosis (MS). In the quest for possible cures for these diseases, it is important that we understand how connections are established between neurons. Neurons have a number of long thin offshoots - called axons - that conduct electrical impulses. These primary elements of i...

New system could drastically reduce herbicide use

...d robot with 20/20 vision, on a search-and-destroy quest for weeds, will soon be moving up and down the crop rows at the experimental fields at the University of Illinois. What's more, this robot has the potential to control weeds while significantly reducing herbicide use. The robot uses GPS for navigati...

...ssful." Swaroop sees several next steps in his quest to find treatments for retinal and macular degeneration. His research team will continue to study the properties of photoreceptor cells and mouse models to learn more about the process of transplantation and functional integration. He hopes that he ...

Solution to bacterial mystery promises new drugs

A 25-year quest to identify the first biochemical step that many disease-causing bacteria use to build their membranes has led to a discovery that holds promise for effective, new antibiotics against these bacteria, according to investigators at St. Jude Children's ...

NASA snow data helps maintain nation's largest, oldest bison herd
