... complexes available and probably the set with the highest quality," Aloy says. "Most proteomics studies in the past have shown whether molecules interact or not, in a 'yes/no' way. The completeness of this data lets us see how likely any particular molecule is to bind to another. By combining such measureme...

"These workers represent a medically underserved population that is at risk for bo...

A link is found between morphine addiction and the tendency to explore

...hildren, who are going through the period with the highest risk," explains Doctor Nadal. To determine a rat's level of addiction to morphine, the researchers used the place-conditioning technique. In these tests, a special cage is used that has two very different compartments, with a distinct colour, feel a...

2005 was the warmest year in a century

...ace Studies (GISS) in New York City noted that the highest global annual average surface temperature in more than a century was recorded in their analysis for the 2005 calendar year. Some other research groups that study climate change rank 2005 as the second warmest year, based on comparisons through Novem...

...rning and memory performance. Because ghrelin is highest in the circulation during the day and when the stomach is empty, these results also indicate that learning may be most effective before meal-time. "Based on our observations in animal models, a practical recommendation could be that children may ben...

H5N1 avian flu virus vaccine induces immune responses in healthy adults

Cortex matures faster in youth with highest IQ

...s by the teen years, the superior group showed the highest rates of change. "Brainy children are not cleverer solely by virtue of having more or less gray matter at any one age," explained Rapoport. "Rather, IQ is related to the dynamics of cortex maturation."The observed differences are consistent with fi...

In Xenopus eggs, however, Fanconi proteins are stockpiled in preparation for the rapid divisions that occur after fertilization. Plus, the divisions occur at the same time, or synchronously, allowing naturally regulated sta...

Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm

In an effort to identify risk factors with a genetic foundation, the researchers took the unconventional approach of starting from scratch and not looking at genes already known or suspected to be involved in heart rhythm. "Studying individu...

They will also investigate how the project contributes to the debate about the ethics of stem cell research. In particular, they will consider how potential benefits of these stem cell therapies can be weighed agains...

Parents need to be educated about HPV vaccinations for daughters

Tragically, its regions of highest incidence are those in which preventative screening cannot be provided due to lack of resources, and those least well equipped to treat the condition for the same reason. "In more affluent well-developed countries, cervical screening by means of c...

Birth defects: 8 million annually worldwide

... Dr. Howson says. "Such comparisons show that the highest birth defects prevalence is found among the world's poorest countries, whereas many of the lowest rates are found among the world's wealthier countries." Worldwide, the birth prevalence of all genetic birth defects combined range from a high of 82 p...

Human trial proves ricin vaccine safe, induces neutralizing antibodies; further tests planned

...five of the individuals in the group receiving the highest vaccine dose produced ricin-neutralizing antibodies in their blood, indicating their immune systems had responded. Four of five in the intermediate dose group produced antibodies, while one of five in the lowest dose group did so. The human-produce...

NASA's AURA satellite peers into Earth's ozone hole

The level was 102 Dobson Units (the system of measurement designated to gauge ozone thickness). That is approximately one-half as thick as the layer before 1980 during th...

'Computer-chemistry' yields new insight into a puzzle of cell division

...different software program that could identify the highest and lowest places on the molecules' surfaces, and where "highest" on one might fit into the "deepest" on the other. "That's not easy, because there is no point of reference on those complicated shapes," Rudolph said. The researchers finally winnowed...

Patients' risk of developing tuberculosis more than doubled if HAART did not successfully control their HIV. Patients were also more likely to develop TB if they were...
