Jülich scientists have discovered the mechanism behind Parkinsonian tremor and developed a new deep brain pacemaker to disrupt it. The device influences disturbed neurons in the core region of the brain, causing irregular rhythms that break down diseased modes.
Researchers have developed an analytical method using Empirical Mode Decomposition (EMD) to classify a wider range of heart sounds than skilled physicians can. The EMD system, trained with AI algorithms, outperforms conventional methods in identifying murmurs and other anomalies.
Researchers at Washington University in St. Louis found that humans inspect objects more thoroughly when their hands are near them, indicating a new insight into brain wiring that could impact rehabilitative therapy techniques and prosthetic design.
Researchers identified 39 histone modifications and a core set of 17 associated with active genes. These combinations, known as 'backbone sets,' were found to be present in more than a quarter of promoter regions, suggesting specific meanings for specific patterns of modification.
Using an engineered virus, UCLA researchers locate prostate cancer cells in the pelvic lymph nodes, where it spreads first before invading other organs. The discovery may lead to more effective diagnostic and therapeutic approaches for advanced prostate cancer.
Researchers used fMRI scans to study children's responses to pain and found that their brains showed similar activation patterns to adults. The study also discovered additional brain regions activated when children saw someone intentionally hurt by another individual.
Researchers have discovered that a natural compound from magnolia cones can block a previously 'undruggable' pathway for cancer growth. This finding could lead to the development of new treatments by making tumors more sensitive to traditional chemotherapy drugs.
Researchers at University of Western Ontario found a link between brain ventricle size and cognitive impairment in Alzheimer's patients. They suggest that MRI scans can measure ventricle changes to provide earlier diagnosis and assess treatment effectiveness.
Rice University will establish its first Ph.D. program in sociology, focusing on Houston's social environment and its implications for modern cities. The graduate studies will integrate academic and public sociology through explorations of human society in major urban environments.
A new study by University of Illinois and Harvard University researchers found that non-parental care of infants is associated with higher rates of overweight and unfavorable feeding practices. Infants in child-care settings were more likely to be overfed or underfed, leading to weight gain.
The newly established Solar Power Laboratory aims to advance solar energy research and development while improving the efficiency of solar electric power systems. Researchers will collaborate with industry partners to accelerate the expansion of Arizona's renewable energy economy.
A study published in the journal Addiction found that sexual behavior counseling during drug addiction treatment can decrease risky sexual behavior and HIV transmission in Russian substance-dependent individuals. The PREVENT program, a behavioral intervention, was effective in increasing safe sex among participants.
A landmark study found that college environments with easy access to alcohol, weak control policies, and lax enforcement contribute to binge drinking. Colleges with restrictive policies and substance-free housing options have lower binge drinking levels.
The CSIRO report 'Fuel for thought' explores the challenges and opportunities in reducing greenhouse gas emissions from the transport sector. It suggests that Australia's fuel mix will include expanded use of diesel, gaseous fuels and hybrid electric vehicles to address economic risks associated with rising oil prices and climate change.
The UCSF School of Nursing will continue its research and training activities related to personal care services, focusing on workforce issues and improving access to services for people with disabilities. The center's work aims to provide support for individuals to live and work independently in their community.
Numerous studies have documented adverse effects of lead on wildlife, particularly waterbirds and scavenging species, due to ingested lead shot, bullets, and fishing sinkers. The use of lead ammunition remains common despite bans on waterfowl hunting, with upland game and scavenging birds continuing to be exposed.
