IADR/AADR Journal of Dental Research releases large studies on osteonecrosis of the jaw

Two large studies on osteonecrosis of the jaw (ONJ) published in the IADR/AADR Journal of Dental Research investigate risk factors and prevalence. The studies found that bisphosphonate use is strongly associated with ONJ, and patients with oral bisphosphonates are 15.5 times more likely to have ONJ.

Firefly glow: Berkeley Lab scientists develop a hydrogen peroxide probe based on firefly luciferin

Researchers have developed a new bioluminescent probe that enables real-time detection of hydrogen peroxide levels in mice, allowing for the tracking of infectious diseases or cancerous tumors without harm. The PCL-1 probe has provided evidence that hydrogen peroxide is continuously produced even in healthy animals.

CeBIT 2011: Administration in the cloud

A study by Fraunhofer-Gesellschaft and Hertie School of Governance explores the benefits and risks of cloud computing for public administration in Germany. Researchers are developing application scenarios for interoperable use of cloud-computing technologies, while also creating a Cloud Computing Test Laboratory to test security concepts.

Kids with ADHD much more likely to develop substance abuse problems as they age

A comprehensive review of 27 long-term studies found that children with ADHD are two to three times more likely to develop serious substance abuse problems in adolescence and adulthood. The research, published in Clinical Psychology Review, analyzed data from approximately 4,100 children with ADHD and 6,800 without the disorder.

Web experts ask scientists to use the Web to improve understanding, sharing of their data in science

Researchers Peter Fox and James Hendler outline a new vision for scientific data visualization, encouraging scientists to adopt web-based approaches. They highlight the advantages of interactive and dynamic visualizations, such as those found on the web, which can facilitate collaboration, reduce costs, and increase accessibility.

Stroke medicines still unaffordable for some survivors, according to University of Michigan research

Young, uninsured, or Medicare Part D participants face challenges affording medications after stroke, leading to increased risk of future strokes and cardiovascular disease. The study highlights the need for healthcare professionals to screen for cost-related barriers and improve access to affordable medications for post-stroke patients.

Researchers map out ice sheets shrinking during Ice Age

A set of maps created by the University of Sheffield have illustrated the pattern and speed of shrinkage of the large ice sheet that covered the British Isles during the last Ice Age. The maps use new information on glacial landforms, such as moraines and drumlins, to predict future ice losses in Greenland and Antarctica.

Study shows that defensive military alliances enhance peace

A new study by Rice University researchers found that countries with defensive military alliances are less likely to be attacked, and these alliances do not increase the likelihood of aggression. The study analyzed defense agreements from 1816 to 2001 and suggests that such alliances can make war and militarized conflicts shorter.

44-year-old mystery of how fleas jump resolved

Researchers at Cambridge University have finally resolved the debate on how fleas jump, discovering that they push off with their toes. The team used high-speed cameras and mathematical modeling to analyze flea jumps, finding that both the tarsus and trochanter were involved in the jumping process.

Common insecticide used in homes associated with delayed mental development of young children

A study by Columbia University's Mailman School of Public Health found a significant association between piperonyl butoxide, a common additive in pyrethroid formulations, and delayed mental development in young children. Children exposed to higher levels of PBO showed lower cognitive scores, similar to the impact of lead exposure.

Most stroke patients don't get clot-busting treatment in timely manner, study finds

Researchers found that less than one-third of acute stroke patients treated with clot-busting drug tPA receive it within 60 minutes of hospital arrival. Timely tPA administration is linked to lower in-hospital mortality and fewer complications, with every 15-minute reduction associated with a 5% lower risk of death.

WSU researcher designs multilingual instruction materials for world's largest mall

A WSU researcher designed an instructional process to train over 300 employees from diverse countries in custodial duties at the Dubai Mall. The project resulted in a high success rate and has been recognized as a model for efficient, cross-cultural instructional design.
