Two LSU professors are working to develop survivable sensor networks that can collect valuable data during disasters, which could be used in environmental monitoring, healthcare, and national security projects. The researchers also aim to ensure secure data transmission through methods like anonymous email tracking.
A research team led by OHSU scientists is studying metal homeostasis and its disruption in human cells, focusing on copper and iron concentrations. The project aims to understand the regulation of metals in cells and their impact on disease progression.
A mathematical model helps determine necessary mosquito control levels to prevent West Nile virus outbreaks, reducing economic and environmental damage. The model takes into account regional factors such as mosquito life span and crow biology.
Researchers developed a new ultrasound probe at Mayo Clinic that allows for better visualization of PFO defects, enabling more effective closure with catheter techniques. The results show a 93% success rate in closing the defect without complications.
A new interdisciplinary brain research project has been launched at the University of Illinois, using a $1.5 million Keck Foundation grant to develop tools for understanding and correcting problems in brain circuitry. The goal is to identify natural chemical signatures to restore proper wiring and functioning in malfunctioning brains.
A Stanford team has developed a simplified method for generating siRNA molecules to disable genes, overcoming the technique's limitations in expense and labor. The new protocol allows researchers to create libraries of siRNA molecules for all known genes, enabling the identification of genes that play critical roles in stem cell function.
The chemical industry is expected to experience increased production and demand, leading to historic levels of growth in the US, Canada, and Asia-Pacific. In contrast, European chemical industries are forecasted to exhibit modest growth due to economic constraints.
A randomized, double-blind study found that dietary supplements containing ephedra and caffeine increased the QTc interval duration and systolic blood pressure in healthy volunteers. The authors recommend patients avoid these supplements until more information is known about their safety.
A study published in PLOS Biology discovered a common genetic signature linked to the progression of various cancers, including prostate and liver cell carcinomas. Patients with tumors carrying this signature had an increased risk of metastasis and death compared to those without it.
A study led by Bruce Lahn found that the Abnormal Spindle-Like Microcephaly Associated (ASPM) gene shows strong evidence of accelerated evolutionary changes in the primate lineage leading to humans. These changes are most prominent after humans parted ways from chimpanzees, suggesting a possible key role for ASPM in human brain evolution.
A University of Illinois study highlights the growing tension between farmers and newcomers to rural areas like Elburn, Kane County. Farmers see farmland as a means of livelihood and family heritage, while newcomers view it as public amenity. This clash is leading to erosion of community trust and decline in farming practices.
A study of Medicare-eligible patients with lung, breast, colorectal, and gastrointestinal tumors found a rise in chemotherapy use and emergency room admissions near death. However, an increase in hospice care usage suggests that improved palliative services may reduce aggressive end-of-life treatment.
Research suggests that direct-quality indicators based on patient mortality are more effective in selecting high-performing hospitals for VLBW infants. The study found that hospitals with lower past mortality rates had significantly better outcomes, implying that volume-based standards may not accurately predict quality.
A joint research effort discovered Mars-like soils in Chile's Atacama Desert, which are depleted in organic materials and would have been missed by NASA's Viking missions. The team found that the conditions in this environment represent a limit for microbial life on Earth.
Native C4 plants faced disastrous consequences during prolonged severe droughts in the middle Holocene, contrary to expectations. Weedy C3 plants adapted well due to their ability to exploit limited water resources, highlighting a key difference between C3 and C4 plant responses.
Researchers successfully remyelinated nearly entire mouse brains with human stem cells, producing thousands of times more myelin than previous experiments. This breakthrough offers potential treatment for diseases like Canavan disease and Tay-Sachs disease.
Researchers have identified wound-healing genes that are active in prostate and liver cancers, which are more aggressive and likely to spread. This discovery could lead to personalized treatment options by matching patients with specific drugs targeting these abnormal proteins.
A recent study found that hospital procedural volume is only modestly associated with risk-adjusted CABG mortality rates, suggesting that other measures are needed to assess quality. Low-volume hospitals often achieve excellent outcomes despite operating on higher-risk patients.
The Environmental Polymorphism Registry aims to investigate the interaction between genes and environment. Researchers will analyze DNA samples from 20,000 participants to identify genetic variants associated with environmental exposure.
The Stanford University Program on Energy and Sustainable Development has received a grant from BP to accelerate research on market-based policies addressing global warming. The partnership aims to complement technical research with similar work on the legal, political, and institutional dimensions of energy value derivation.
The system uses computer models to predict impacts of cities on regional and global land and atmospheric processes. By incorporating local energy and water cycles, predictions can be applied to climate and weather forecasting, agricultural management, and hazard mitigation.
