The innovation addresses second-generation bioethanol challenges, enabling more efficient and sustainable production.
Scientists are using various imaging techniques, including MRI and CT scans, to study chronic obstructive pulmonary disease (COPD) and develop a better understanding of the disease. The research aims to categorize COPD patients into two major groups based on airway dysfunction and lung tissue damage.
Researchers found that adding a genetic sonogram to non-invasive prenatal screening increases the detection rate of Down syndrome by up to 98%, while decreasing false positive rates. This maximizes the capacity for noninvasive detection with currently available technology.
NJIT researchers are awarded nearly $4.3 million in NSF funding to improve the Big Bear Solar Observatory and study various aspects of solar energy, including its impact on terrestrial telecommunications and power systems.
Researchers discovered a new antioxidant system that shields single cysteine residues from oxidative harm, reducing cancer and heart disease risk
Researchers will study the entire power plant system to identify opportunities for energy and cost savings in carbon capture and compression. The goal is to recover heat generated during compression and use it to improve power plant efficiency.
Scientists have identified a gene, AEG-1, that plays a pivotal role in two processes essential for tumor development, growth, and progression to metastasis. The gene's expression is involved in oncogenic transformation and angiogenesis, critical steps for tumor progression.
The European Society of Cardiology will hold a Joint Scientific Forum on optimal diabetes management in Beijing, Shanghai, and Guangzhou. Experts will explore the link between diabetes and heart disease, and discuss treatment strategies for Asian patients.
Researchers developed an Android app called PowerTutor to help users compare the power consumption of different applications. The app provides real-time information on how phone components use power, enabling users to make informed decisions about their device's energy efficiency.
Researchers found a direct connection between childhood psychological trauma and accelerated reduction in telomere size, which promotes cellular stability. Telomeres typically shorten with age, but the study shows that childhood abuse can accelerate this process.
Researchers have discovered how a 'genetic symphony' of genes affects plant development, enabling potential disease resistance and increased yields. The study found that combining different ACS genes regulates ethylene production, which impacts various aspects of plant growth.
A large-scale genetic analysis of 17,296 women identified 43 genetic loci contributing to lipoprotein metabolism, providing new insights into the molecular basis of cardiovascular disease. The study also quantifies the contribution of common genetic variation to plasma lipoprotein concentrations.
